Basis of Presentation

2. Basis of Presentation

The Company’s consolidated financial statements refer to Herbalife Nutrition Ltd. and its subsidiaries.

On April 24, 2018, the Company’s shareholders approved a two-for-one stock split of the Company’s common shares. On May 14, 2018, shareholders of record received one additional share for each share held as of May 7, 2018. All share and per share amounts herein have been restated to reflect the stock split.

Recently Adopted Pronouncements

In May 2014, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, No. 2014-09, Revenue from Contracts with Customers (Topic 606). The new revenue recognition standard provides a five-step analysis of contracts to determine when and how revenue is recognized. The core principle is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In August 2015, the FASB deferred the effective date of ASU No. 2014-09 for all entities by one year to annual reporting periods beginning after December 15, 2017. The FASB has issued several updates subsequently, including implementation guidance on principal versus agent considerations, on how an entity should account for licensing arrangements with customers, and to improve guidance on assessing collectability, presentation of sales taxes, noncash consideration, and contract modifications and completed contracts at transition. The amendments in this series of updates shall be applied either retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. The Company adopted FASB Accounting Standards Codification, or ASC, Topic 606, Revenue from Contracts with Customers, or ASC 606, with a date of initial application of January 1, 2018 using the modified retrospective method applied to all contracts existing as of January 1, 2018. Results for reporting periods beginning January 1, 2018 and thereafter are presented under ASC 606, while prior period amounts have not been adjusted and continue to be reported in accordance with FASB ASC Topic 605, Revenue Recognition, or ASC 605. The Company recorded a net reduction of $2.3 million to beginning retained earnings as of January 1, 2018 due to the cumulative impact of adopting ASC 606 resulting from revenue recognition timing differences related to the transfer of control of products sold through certain of the Company’s third-party importers which are not material. The cumulative impact to opening balance sheet accounts was not material. Additionally, certain third-party importer fees have changed classification from a reduction to revenue to selling, general, and administrative expense under ASC 606. For more information on the transitional impact of adopting ASC 606, see the section entitled “Revenue Recognition” below.

In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments — Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The updated guidance enhances the reporting model for financial instruments by modifying how entities measure and recognize equity investments and present changes in the fair value of financial liabilities, and by simplifying the disclosure guidance for financial instruments. The adoption of this guidance during the first quarter of 2018 did not have a material impact on the Company’s consolidated financial statements.

In March 2016, the FASB issued ASU No. 2016-04, Liabilities — Extinguishments of Liabilities (Subtopic 405-20): Recognition of Breakage for Certain Prepaid Stored-Value Products. This ASU requires entities that sell prepaid stored-value products redeemable for goods, services or cash at third-party merchants to recognize breakage (i.e. the value that is ultimately not redeemed by the consumer) in a way that is consistent with how it will be recognized under the new revenue recognition standard. Under prior U.S. GAAP, there was diversity in practice in how entities accounted for breakage that resulted when a consumer did not redeem the entire product balance. This ASU clarifies that an entity’s liability for prepaid stored-value products within its scope meets the definition of a financial liability. The adoption of this guidance during the first quarter of 2018 did not have a material impact on the Company’s consolidated financial statements.

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. This ASU provides clarification on eight specific cash flow issues regarding presentation and classification in the statement of cash flows with the objective of reducing the existing diversity in practice. The adoption of this guidance during the first quarter of 2018 did not have a material impact on the Company’s consolidated financial statements.

In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory. This ASU requires that entities recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The amendments in this update do not change U.S. GAAP for the pre-tax effects of an intra-entity asset transfer under Topic 810, Consolidation, or for an intra-entity transfer of inventory. The adoption of this guidance during the first quarter of 2018 did not have a material impact on the Company’s consolidated financial statements.

In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. This ASU requires that restricted cash and restricted cash equivalents be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period amounts shown on the statements of cash flows. The adoption of this guidance during the first quarter of 2018 resulted in a change in the presentation of restricted cash and restricted cash equivalents in the Company’s consolidated statements of cash flows for all periods presented. Other than this change, the adoption of this guidance did not have a material impact on the Company’s consolidated financial statements.

In May 2017, the FASB issued ASU No. 2017-09, Compensation — Stock Compensation (Topic 718): Scope of Modification Accounting. This ASU provides additional guidance for when a company should apply modification accounting when there is a change in either the terms or conditions of a share-based payment award. Specifically, a company should not apply modification accounting if the fair value, vesting conditions, and classification of the award remains the same immediately before and after the modification. The adoption of this guidance during the first quarter of 2018 did not have a material impact on the Company’s consolidated financial statements.

New Accounting Pronouncements

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) and subsequently issued additional updates to Topic 842. The updated guidance requires lessees to recognize a lease liability and a right-of-use asset, measured at the present value of the future minimum lease payments, at the lease commencement date. Recognition, measurement and presentation of expenses will depend on classification as a finance or operating lease. The amendments also require certain quantitative and qualitative disclosures. ASU 2016-02 is effective for all interim and annual reporting periods beginning after December 15, 2018, with early adoption permitted. As currently issued, the update requires entities to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach or allows entities to initially apply the new lease standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The Company has performed a comprehensive review in order to determine what changes were required to support the adoption of this new standard. During the first quarter of 2019, the Company will complete its implementation of its processes and policies to support the new lease accounting and reporting requirements. The Company plans to adopt the new standard on the adoption date with an application date of January 1, 2019 and recognize a cumulative-effect adjustment to the opening balance of retained earnings, if any, in the period of adoption. Based on its lease portfolio as of January 1, 2019, the Company preliminarily estimates the impact of adopting ASU 2016-02 to increase both its total assets and total liabilities in the range of $150 million to $200 million. The Company does not anticipate the adoption of this guidance to have a material impact on its consolidated statements of income. The Company continues to finalize the implementation of new processes and the assessment of the impact of this adoption on its consolidated financial statements; therefore, the preliminary estimated impacts disclosed can change and the final impact will be known once the adoption is completed during the first quarter of 2019.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instrument — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This ASU changes the impairment model for most financial assets, requiring the use of an expected loss model which requires entities to estimate the lifetime expected credit loss on financial assets measured at amortized cost. Such credit losses will be recorded as an allowance to offset the amortized cost of the financial asset, resulting in a net presentation of the amount expected to be collected on the financial asset. In addition, credit losses relating to available-for-sale debt securities will now be recorded through an allowance for credit losses rather than as a direct write-down to the security. The amendments in this update are effective for reporting periods beginning after December 15, 2019, with early adoption permitted for reporting periods beginning after December 15, 2018. The Company is evaluating the potential impact of this adoption on its consolidated financial statements.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles — Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This ASU simplifies the test for goodwill impairment by removing Step 2 from the goodwill impairment test. Companies will now perform the goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount, recognizing an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value not to exceed the total amount of goodwill allocated to that reporting unit. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The amendments in this update are effective for goodwill impairment tests in fiscal years beginning after December 15, 2019, with early adoption permitted for goodwill impairment tests performed after January 1, 2017. The Company is evaluating the potential impact of this adoption on its consolidated financial statements.

In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities. This ASU improves the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements and makes certain targeted improvements to simplify the application of existing hedge accounting guidance. The amendments in this update are effective for reporting periods beginning after December 15, 2018, with early adoption permitted. The adoption of this guidance will not have a material impact on the Company’s consolidated financial statements.

In February 2018, the FASB issued ASU No. 2018-02, Income Statement — Reporting Comprehensive Income (Topic 220). This ASU allows a reclassification from accumulated other comprehensive income to retained earnings for tax effects of items within accumulated other comprehensive income, or stranded tax effects, resulting from the Tax Cuts and Jobs Act and requires certain disclosures about those stranded tax effects. The amendments in this update are effective for reporting periods beginning after December 15, 2018, with early adoption permitted.

The Company is evaluating the potential impact of this adoption on its consolidated financial statements.

Significant Accounting Policies

Consolidation Policy

The consolidated financial statements include the accounts of Herbalife Nutrition Ltd. and its subsidiaries. All significant intercompany transactions and accounts have been eliminated.

Foreign Currency Translation and Transactions

In the majority of the countries that the Company operates, the functional currency is the local currency. The Company’s foreign subsidiaries’ asset and liability accounts are translated for consolidated financial reporting purposes into U.S. dollar amounts at year-end exchange rates. Revenue and expense accounts are translated at the average rates during the year. Foreign exchange translation adjustments are included in accumulated other comprehensive loss on the accompanying consolidated balance sheets. Foreign currency transaction gains and losses, which include the cost of foreign currency derivative contracts and the related settlement gains and losses but excluding certain foreign currency derivatives designated as cash flow hedges as discussed in Note 11, Derivative Instruments and Hedging Activities, are included in selling, general, and administrative expenses within the accompanying consolidated statements of income. The Company recorded net foreign currency transaction losses of $17.3 million, $13.7 million, and $11.4 million, for the years ended December 31, 2018, 2017, and 2016, respectively.

Forward Exchange Contracts

The Company enters into foreign currency derivatives, primarily comprised of foreign currency forward contracts, in managing its foreign exchange risk on sales to Members, inventory purchases denominated in foreign currencies, and intercompany transactions and loans. The Company does not use the contracts for trading purposes.

In accordance with FASB ASC Topic 815, Derivatives and Hedging, or ASC 815, the Company designates certain of its derivative instruments as cash flow hedges and formally documents its hedge relationships, including identification of the hedging instruments and the hedged items, as well as its risk management objectives and strategies for undertaking the hedge transaction, at the time the derivative contract is executed. The Company assesses the effectiveness of the hedge both at inception and on an ongoing basis and determines whether the hedge is highly or perfectly effective in offsetting changes in cash flows of the hedged item. The Company records the effective portion of changes in the estimated fair value in accumulated other comprehensive loss and subsequently reclassifies the related amount of accumulated other comprehensive loss to earnings when the hedged item and underlying transaction impacts earnings. If it is determined that a derivative has ceased to be a highly effective hedge, the Company will discontinue hedge accounting for such transaction. For derivatives that are not designated as hedges, all changes in estimated fair value are recognized in the consolidated statements of income.

Cash and Cash Equivalents

The Company considers all highly liquid investments purchased with a maturity of three months or less to be cash equivalents. Cash and cash equivalents are comprised primarily of foreign and domestic bank accounts, and money market funds. These cash and cash equivalents are valued based on Level 1 inputs which consist of quoted prices in active markets. To reduce its credit risk, the Company monitors the credit standing of the financial institutions that hold the Company’s cash and cash equivalents.

The Company has a cash pooling arrangement with a financial institution for cash management purposes. This cash pooling arrangement allows certain of the Company’s participating subsidiaries to withdraw cash from this financial institution based upon the Company’s aggregate cash deposits held by subsidiaries who participate in the cash pooling arrangement. To the extent any participating location on an individual basis is in an overdraft position, these overdrafts will be recorded as liabilities and reflected as financing activities in the Company’s consolidated balance sheets and consolidated statement of cash flows, respectively. As of December 31, 2018 and 2017, the Company did not owe any amounts to this financial institution.

Accounts Receivable

Accounts receivable consist principally of receivables from credit card companies, arising from the sale of products to the Company’s Members, and receivables from importers, who are utilized in a limited number of countries to sell products to Members. The Company believes the concentration of its collection risk related to its credit card receivables is diminished due to the geographic dispersion of its receivables. The receivables from credit card companies were $52.7 million and $68.1 million as of December 31, 2018 and 2017, respectively. Substantially all of the receivables from credit card companies were current as of December 31, 2018 and 2017. For the Company’s receivables from its importers, the Company performs ongoing credit evaluations of its importers and maintains an allowance for potential credit losses. The Company considers customer credit-worthiness, past and current transaction history with the customer, contractual terms, current economic industry trends, and changes in customer payment terms when determining whether collectability is reasonably assured and whether to record allowances for its receivables. If the financial condition of the Company’s customers deteriorates and adversely affects their ability to make payments, additional allowances will be recorded. The Company believes that it provides adequate allowances for receivables from its Members and importers which are not material to its consolidated financial statements. During the years ended December 31, 2018, 2017, and 2016, the Company recorded $1.2 million, $0.9 million, and $1.0 million, respectively, in bad-debt expense related to allowances for the Company’s receivables. As of December 31, 2018 and 2017, the Company’s allowance for doubtful accounts was $1.5 million and $1.2 million, respectively. As of December 31, 2018 and 2017, the majority of the Company’s total outstanding accounts receivable were current.

Fair Value of Financial Instruments

The Company applies the provisions of FASB authoritative guidance as it applies to its financial and non-financial assets and liabilities. The FASB authoritative guidance clarifies the definition of fair value, prescribes methods for measuring fair value, establishes a fair value hierarchy based on the inputs used to measure fair value, and expands disclosures about fair value measurements.

The Company has estimated the fair value of its financial instruments using the following methods and assumptions:

•

The carrying amounts of cash and cash equivalents, receivables and accounts payable approximate fair value due to the short-term maturities of these instruments;

•

The fair value of option and forward contracts are based on dealer quotes;

•

The Company’s variable rate revolving credit facility is recorded at carrying value and is considered to approximate its fair value;

•

The outstanding borrowings on the Company’s term loan A under its senior secured credit facility are recorded at carrying value, and their fair value is determined by utilizing over-the-counter market quotes for similar instruments;

•

The outstanding borrowings on the Company’s term loan B under its senior secured credit facility are recorded at carrying value, and their fair value is determined by utilizing over-the-counter market quotes;

•

The Company’s convertible senior notes issued in February 2014, or the 2019 Convertible Notes, and convertible senior notes issued in March 2018, or the 2024 Convertible Notes, are recorded at carrying value, and their fair values are determined using two valuation methods as described further in Note 4, Long-Term Debt;

•

The Company’s senior notes issued in August 2018, or the 2026 Notes, are recorded at carrying value, and their fair value is determined by utilizing over-the-counter market quotes and yield curves; and

•

The fair value of the non-transferable contractual contingent value right, or CVR, provided to participants in connection with the modified Dutch auction tender offer completed in October 2017 is based on a lattice model, which includes inputs such as the underlying stock price, strike price, time to expiration, and dividend yield, as well as the probability of a going-private transaction. See Note 8, Shareholders’ Deficit, for a further description of the tender offer and the CVR.

Inventories

Inventories are stated at lower of cost (primarily on the first-in, first-out basis) and net realizable value.

Debt Issuance Costs

Debt issuance costs represent fees and expenses related to the borrowing of the Company’s long-term debt and are amortized over the term of the related debt using the effective interest method. Debt issuance costs, except for the Company’s revolving credit facility, are recorded as a reduction to debt (contra-liability) within the Company’s consolidated balance sheets. Total amortization expense related to debt issuance costs were $7.3 million, $8.4 million, and $7.9 million for the years ended December 31, 2018, 2017, and 2016, respectively. As of December 31, 2018 and 2017, the Company’s remaining unamortized debt issuance costs were $26.5 million and $26.2 million, respectively.

Long-Lived Assets

As of December 31, 2018 and 2017, the Company’s net property, plant and, equipment consisted of the following:

	December 31,
	2018			2017
	(in millions)
Property, plant, and equipment, at cost:
Land and buildings	$	51.1		$	51.0
Furniture and fixtures		26.1			26.7
Equipment		849.4			803.5
Building and leasehold improvements		198.5			199.0
Total property, plant, and equipment, at cost		1,125.1			1,080.2
Less: accumulated depreciation and amortization		(765.1	)		(702.7	)
Property, plant, and equipment, at cost, net of accumulated depreciation and amortization	$	360.0		$	377.5

In December 2012, the Company purchased an approximate 800,000 square foot facility in Winston-Salem, North Carolina, for approximately $22.2 million. The Company allocated $18.8 million and $3.4 million between buildings and land respectively, based on their relative fair values. In April 2016, the Company purchased one of its office buildings in Torrance, California, which it had previously leased, for approximately $29.6 million. The Company allocated $16.9 million and $11.6 million, which was net of the deferred rent liability of $1.1 million, between buildings and land, respectively, based on their relative fair values. As of December 31, 2018 and 2017, these amounts have been reflected in Property, plant and equipment within the Company’s accompanying consolidated balance sheets.

Depreciation of furniture, fixtures, and equipment (including computer hardware and software) is computed on a straight-line basis over the estimated useful lives of the related assets, which range from three to ten years. The Company capitalizes eligible costs to acquire or develop internal-use software that are incurred subsequent to the preliminary project stage. Computer hardware and software, the majority of which is comprised of capitalized internal-use software costs, were $163.2 million and $157.3 million as of December 31, 2018 and 2017, respectively, net of accumulated depreciation. Leasehold improvements are amortized on a straight-line basis over the life of the related asset or the term of the lease, whichever is shorter. Buildings are depreciated over 40 years. Building improvements are generally depreciated over ten to fifteen years. Land is not depreciated. Depreciation and amortization expenses recorded to Selling, general, and administrative expenses totaled $80.8 million, $80.1 million, and $80.7 million, for the years ended December 31, 2018, 2017, and 2016, respectively.

Long-lived assets are reviewed for impairment based on undiscounted cash flows whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Measurement of an impairment loss is based on the estimated fair value of the asset.

Goodwill and marketing-related intangible assets with indefinite lives are evaluated on an annual basis for impairment or more frequently if events or changes in circumstances indicate that the asset might be impaired. For goodwill, the Company performed a qualitative assessment during the fourth quarter of 2018 and determined that it is not likely that the fair value of each reporting unit is less than its respective carrying value. If it is determined that it is more likely than not that the fair value of a reporting unit is less than its carrying amount or if a qualitative assessment is not performed, then the Company would perform the two-step goodwill impairment test as required, in which it would use a discounted cash flow approach to estimate the fair value of a reporting unit. If the fair value of the reporting unit is less than the carrying value, then the implied fair value of the goodwill must be determined. If the implied fair value of the goodwill is less than its carrying value, then a goodwill impairment amount is recorded for the difference. For the marketing-related intangible assets, the Company performed a qualitative assessment during the fourth quarter of 2018 and determined that it is not likely that the fair value of the assets is less than their carrying value. If it is determined that it is more likely than not that the fair value of the assets is less than their carrying amount or if a qualitative assessment is not performed, then the Company would perform the quantitative impairment test as required, in which it would use a discounted cash flow model under the relief-from-royalty method in order to determine the fair value. If the fair value is less than its carrying value, then an impairment amount is recorded for the difference. During the years ended December 31, 2018, 2017, and 2016, there were no additions to goodwill or marketing-related intangible assets or impairments of goodwill or marketing-related intangible assets. As of both December 31, 2018 and 2017, the marketing-related intangible asset balance was $310.0 million which consisted of the Company’s trademark, trade name, and marketing franchise. As of December 31, 2018 and 2017, the goodwill balance was $92.9 million and $96.9 million, respectively. The decrease in goodwill during the year ended December 31, 2018 was due to cumulative translation adjustments.

Restricted Cash

The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported within the Company’s consolidated balance sheets that sum to the total of the same such amounts shown in the Company’s consolidated statements of cash flows:

	December 31,
	2018		2017
	(in millions)
Cash and cash equivalents	$	1,198.9	$	1,278.8
Restricted cash included in Prepaid expenses and other current assets		3.3		4.0
Restricted cash included in Other assets		12.8		12.7
Total cash, cash equivalents, and restricted cash shown in the statement of cash flows	$	1,215.0	$	1,295.5

The majority of the Company’s consolidated restricted cash is held by certain of its foreign entities and consists of cash deposits that are required due to the business operating requirements in those jurisdictions.

Income Taxes

Income tax expense includes income taxes payable for the current year and the change in deferred income tax assets and liabilities for the future tax consequences of events that have been recognized in the Company’s financial statements or income tax returns. A valuation allowance is recognized to reduce the carrying value of deferred income tax assets if it is believed to be more likely than not that a component of the deferred income tax assets will not be realized.

The Company accounts for uncertainty in income taxes in accordance with FASB authoritative guidance which clarifies the accounting and reporting for uncertainties in income taxes recognized in an enterprise’s financial statements. This guidance prescribes a comprehensive model for the financial statement recognition, measurement, presentation and disclosure of uncertain tax positions taken or expected to be taken in income tax returns.

On December 22, 2017, the U.S. enacted the 2017 Tax Cuts and Jobs Act which contained several key tax provisions that affected the Company, including, but not limited to, a one-time mandatory transition tax on accumulated foreign earnings, changes in the sourcing and calculation of foreign income, and a reduction of the corporate income tax rate to 21% effective January 1, 2018. The Company was required to recognize the effect of the tax law changes in the period of enactment, such as determining the transition tax, remeasuring its U.S. deferred tax assets and liabilities as well as reassessing the net realizability of its deferred tax assets and liabilities. In December 2017, the SEC staff issued Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act, which allowed the Company to record provisional amounts during a measurement period not to extend beyond one year of the enactment date. See Note 12, Income Taxes, for a further description on income taxes and the impact of the U.S. Tax Reform. The Company has made an accounting policy election to account for global intangible low-taxed income as a period cost if and when incurred.

Royalty Overrides

Certain Members may earn commissions, called royalty overrides which include production bonuses, based on retail sales volume. Royalty overrides are based on the retail sales volume of certain other Members who are sponsored directly or indirectly by the Member. Royalty overrides are recorded when the products are delivered and revenue is recognized. The royalty overrides are compensation to Members for services rendered including the development, retention and the improved productivity of their sales organizations. As such royalty overrides are classified as an operating expense. Non-U.S. royalty override checks that have aged, for a variety of reasons, beyond a certainty of being paid, are taken back into income. Management has estimated this period of certainty to be three years worldwide.

Distributor Compensation – U.S.

In the U.S., distributor compensation, including Royalty overrides, is capped if the Company does not meet an annual requirement as described in the consent order discussed in more detail in Note 7, Contingencies. On a periodic basis, the Company evaluates if this requirement will be achieved by year-end to determine if a cap on distributor compensation will be required, and then determines the appropriate amount of distributor compensation expense, which may vary in each reporting period. The Company determined that the cap to distributor compensation will not be applicable for the year ended December 31, 2018 as the annual requirement was met.

Comprehensive Income

Comprehensive income consists of net income, foreign currency translation adjustments, the effective portion of the unrealized gains or losses on derivatives, and unrealized gains or losses on available-for-sale investments. See Note 8, Shareholders’ Deficit, for the description and detail of the components of accumulated other comprehensive loss.

Operating Leases

The Company leases most of its physical properties under operating leases. Certain lease agreements generally include rent holidays and tenant improvement allowances. The Company recognizes rent holiday periods on a straight-line basis over the lease term beginning when the Company has the right to the leased space. The Company also records tenant improvement allowances and rent holidays as deferred rent liabilities and amortizes the deferred rent over the terms of the lease to rent expense.

Research and Development

The Company’s research and development is performed by in-house staff and outside consultants. For all periods presented, research and development costs were expensed as incurred and were not material.

Other Operating Income

To encourage local investment and operations, governments in various China provinces conduct grant programs. The Company applied for and received several such grants in China. Government grants are recorded into income when a legal right to the grant exists, there is a reasonable assurance that the grant proceeds will be received, and the substantive conditions under which the grants were provided have been met. Generally, these substantive conditions are the Company maintaining operations and paying certain taxes in the relevant province and obtaining government approval by completing an annual application process. The Company believes the continuing obligation with respect to the funds is a general requirement that they are used only for its business in China. The Company recognized government grant income of approximately $29.8 million, $50.8 million, and $34.2 million during the years ended December 31, 2018, 2017, and 2016, respectively, in other operating income within its consolidated statements of income, related to its regional headquarters and distribution centers within China. The Company intends to continue applying for government grants in China when programs are available; however, there is no assurance that the Company will receive grants in future periods.

On October 30, 2016, an arbitration tribunal awarded the Company approximately $29.7 million in connection with the re-audit of the Company’s 2010 to 2012 financial statements after the resignation of KPMG as the Company’s independent registered public accounting firm. This amount has been recognized in other operating income within the Company’s consolidated statement of income for the year ended December 31, 2016.

Professional Fees

The Company expenses professional fees, including legal fees, as incurred. These professional fees are included in selling, general, and administrative expenses within the Company’s consolidated statements of income.

Advertising

Advertising costs, including Company sponsorships, are expensed as incurred and amounted to approximately $41.1 million, $55.7 million, and $64.8 million for the years ended December 31, 2018, 2017, and 2016, respectively. These expenses are included in selling, general, and administrative expenses within the Company’s consolidated statements of income.

Earnings Per Share

Basic earnings per share represents net income divided by the weighted-average number of common shares outstanding for the period. Diluted earnings per share represents net income divided by the weighted-average number of common shares outstanding, inclusive of the effect of dilutive securities, such as outstanding stock appreciation rights, or SARs, stock units, and convertible notes.

The following are the common share amounts used to compute the basic and diluted earnings per share for each period:

	Year Ended December 31,
	2018		2017		2016
	(in millions)
Weighted-average shares used in basic computations		140.2		158.5		166.1
Dilutive effect of exercise of equity grants outstanding		6.3		7.2		6.1
Dilutive effect of 2019 Convertible Notes		3.0		—		—
Weighted-average shares used in diluted computations		149.5		165.7		172.2

There were an aggregate of 1.4 million, 6.9 million, and 9.1 million of equity grants, consisting of SARs and stock units that were outstanding during the years ended December 31, 2018, 2017, and 2016, respectively, but were not included in the computation of diluted earnings per share because their effect would be anti-dilutive or the performance condition of the award had not been satisfied.

Since the Company will settle the principal amount of its 2019 Convertible Notes in cash and settle the conversion feature for the amount above the conversion price in common shares, or the conversion spread, the Company uses the treasury stock method for calculating any potential dilutive effect of the conversion spread on diluted earnings per share, if applicable. The conversion spread will have a dilutive impact on diluted earnings per share when the average market price of the Company’s common shares for a given period exceeds the conversion price of the 2019 Convertible Notes. The dilutive impact for the year ended December 31, 2018 is disclosed in the table above. For the years ended December 31, 2017 and 2016, the 2019 Convertible Notes have been excluded from the computation of diluted earnings per share, as the effect would be anti-dilutive since the conversion price of the 2019 Convertible Notes exceeded the average market price of the Company’s common shares for the years ended December 31, 2017 and 2016. The initial conversion rate and conversion price for the 2019 Convertible Notes are described further in Note 4, Long-Term Debt.

For the 2024 Convertible Notes, the Company has the intent and ability to settle the principal amount in cash and intends to settle the conversion feature for the amount above the conversion price, or the conversion spread, in common shares. The Company uses the treasury stock method for calculating any potential dilutive effect of the conversion spread on diluted earnings per share, if applicable. The conversion spread will have a dilutive impact on diluted earnings per share when the average market price of the Company’s common shares for a given period exceeds the conversion price of the 2024 Convertible Notes. For the year ended December 31, 2018, the 2024 Convertible Notes have been excluded from the computation of diluted earnings per share, as the effect would be anti-dilutive since the conversion price of the 2024 Convertible Notes exceeded the average market price of the Company’s common shares for the year ended December 31, 2018. The initial conversion rate and conversion price for the 2024 Convertible Notes are described further in Note 4, Long-Term Debt.

The capped call transactions executed in connection with the issuance of the 2019 Convertible Notes are excluded from the calculation of diluted earnings per share because their impact is always anti-dilutive. Additionally, the prepaid forward share repurchase transactions executed in connection with the issuance of the 2019 Convertible Notes are treated as retired shares for basic and diluted EPS purposes. See Note 8, Shareholders’ Deficit, for additional discussion regarding the Capped Call Transactions and Forward Transactions.

See Note 8, Shareholders’ Deficit, for a discussion of how common shares repurchased by the Company’s indirect wholly-owned subsidiary are treated under U.S. GAAP.

As a result of applying ASC 606, the impact to the Company’s consolidated balance sheet as of December 31, 2018 was as follows:

	December 31, 2018
	As reported			Impact due to ASC 606			Without adoption
	(in millions)

Total liabilities and shareholders’ deficit		2,789.8			4.4			2,794.2

As a result of applying ASC 606, the impact to the Company’s consolidated statement of income for the year ended December 31, 2018 was as follows:

	Year Ended December 31,
	2018
	As reported			Impact due to ASC 606			Without adoption
	(in millions)

As a result of applying ASC 606, the impact to the Company’s consolidated statement of cash flows as of December 31, 2018 was not material.

The Company’s net sales consist of product sales. In general, the Company's performance obligation is to transfer its products to its Members. The Company generally recognizes revenue when product is delivered to its Members. For China Independent Service Providers and for third-party importers utilized in certain other countries where sales historically have not been material, the Company recognizes revenue based on the Company’s estimate of when the service provider or third-party importer sells the products because the Company is deemed to be the principal party of these product sales under ASC 606 due to the additional selling and operating requirements relating to pricing of products, conducting business with physical locations, and other selling and marketing activities required of the service providers and third-party importers; this timing difference relating to the Company recognizing revenues when these third-party entities sell the products compared to when the Company delivers the products to them did not have a material impact to the Company’s consolidated net sales for the periods presented.

The Company’s Members, excluding its China Independent Service Providers, may receive distributor allowances, which are comprised of discounts, rebates and wholesale commission payments from the Company. Distributor allowances resulting from the Company’s sales of its products to its Members are recorded against net sales because the distributor allowances represent discounts from the suggested retail price.

The Company compensates its sales leader Members with royalty overrides for services rendered, relating to the development, retention, and management of their sales organizations. Royalty overrides are payable based on achieved sales volume. Royalty overrides are classified as an operating expense reflecting the services provided to the Company. The Company compensates its China Independent Service Providers and third-party importers utilized in certain other countries for providing marketing, selling, and customer support services. Under ASC 606, as the Company is the principal party of the product sales as described above, the service fees payable to China Independent Service Providers and the compensation received by third-party importers for the services they provide are recorded in selling, general, and administrative expenses within the Company’s consolidated statements of income. For the periods presented under ASC 605, the service fees payable to its China Independent Service Providers were similarly recognized in selling, general, and administrative expenses within the Company’s consolidated statements of income as they are under ASC 606. However, under ASC 605, the compensation received by third-party importers for the services they provide, which represents the discount provided to them, was recorded as a reduction to net sales, which differs from the treatment under ASC 606 as described above. This change in the accounting treatment under ASC 606 of the compensation for services provided by the Company’s third-party importers did not impact the Company’s consolidated net income and was not material to the Company’s consolidated net sales for the periods presented.

The Company recognizes revenue when it delivers products to its United States Members; distributor allowances, inclusive of discounts and wholesale commissions, are recorded as a reduction to net sales; and royalty overrides are classified as an operating expense.

Shipping and handling services relating to product sales are recognized as fulfillment activities on the Company’s performance obligation to transfer products and are therefore recorded within net sales as part of product sales and are not considered as separate revenues under ASC 606. Shipping and handling revenues related to product sales were $248.0 million, $227.4 million, and $244.2 million for the years ended December 31, 2018, 2017, and 2016, respectively, and represent less than 6% of the Company’s consolidated net sales during each of those years. Shipping and handling costs paid by the Company are included in cost of sales.

The Company presents sales taxes collected from customers on a net basis.

The Company generally receives the net sales price in cash or through credit card payments at the point of sale.

The Company records advance sales deposits when payment is received but revenue has not yet been recognized. In the majority of the Company’s markets, advance sales deposits are generally recorded to income when the product is delivered to its Members. Additionally, advance sales deposits also include deferred revenues due to the timing of revenue recognition for products sold through China Independent Service Providers. The estimated deferral period for advance sales deposits is generally within one week. During the year ended December 31, 2018, the Company recognized substantially all of the revenues that were included within advance sales deposits as of December 31, 2017 and any remaining such balance was not material as of December 31, 2018. Advance sales deposits are included in other current liabilities on the Company’s consolidated balance sheets. See Note 14, Detail of Certain Balance Sheet Accounts, for further information.

In general, if a Member returns product to the Company on a timely basis, they may obtain replacement product from the Company for such returned products. In addition, in general the Company maintains a buyback program pursuant to which it will repurchase products sold to a Member who has decided to leave the business. Allowances for product returns, primarily in connection with the Company’s buyback program, are provided at the time the sale is recorded. This accrual is based upon historical return rates for each country and the relevant return pattern, which reflects anticipated returns to be received over a period of up to 12 months following the original sale. Allowances for product returns were $4.9 million and $3.9 million as of December 31, 2018 and 2017, respectively.

The Company’s products are grouped in five principal categories: weight management; targeted nutrition; energy, sports, and fitness; outer nutrition; and literature and promotional items. However, the effect of economic factors on the nature, amount, timing, and uncertainty of revenue recognition and cash flows are similar among all five product categories. The Company defines its operating segments through six geographic regions. The effect of economic factors on the nature, amount, timing, and uncertainty of revenue recognition and cash flows are similar among the regions with the Company’s Primary Reporting Segment. See Note 10, Segment Information, for further information on the Company’s reportable segments and the Company’s presentation of disaggregated revenue by reportable segment.

Non-Cash Investing and Financing Activities

During the years ended December 31, 2018, 2017, and 2016, the Company recorded $10.2 million, $10.1 million, and $12.7 million, respectively, of non-cash capital expenditures.

During the year ended December 31, 2018, the Company did not record any non-cash borrowings that were used to finance software maintenance. During the years ended December 31, 2017 and 2016, the Company recorded $2.3 million and $20.8 million, respectively, of non-cash borrowings that were used to finance software maintenance. Additionally, see Note 8, Shareholders’ Deficit, for information on the Company’s non-cash financing activities related to the CVR provided to the participants of the October 2017 modified Dutch auction tender offer, as well as share repurchases for which payment was made subsequent to year end.

Share-Based Payments

The Company accounts for share-based compensation in accordance with FASB authoritative guidance which requires the measurement of share-based compensation expense for all share-based payment awards made to employees. The Company measures share-based compensation cost at the grant date, based on the fair value of the award. The Company recognizes share-based compensation expense for service condition awards on a straight-line basis over the employee’s requisite service period. The Company recognizes share-based compensation expense for performance condition awards over the vesting term using the graded vesting method.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions. Such estimates and assumptions affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The Company evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, which the Company believes to be reasonable under the circumstances. The Company adjusts such estimates and assumptions when facts and circumstances dictate. Illiquid credit markets, volatile equity, and foreign currency have combined to increase the uncertainty inherent in such estimates and assumptions. As future events and their effects cannot be determined with precision, actual results could differ from these estimates. Changes in estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods.

Senior Secured Credit Facility

On March 9, 2011, the Company entered into a senior secured credit facility, or the 2011 Credit Facility, which initially consisted of a $700.0 million revolving credit facility, or the 2011 Revolving Credit Facility, with a syndicate of financial institutions as lenders. The 2011 Credit Facility was subsequently amended on July 26, 2012 to include a $500.0 million term loan, or the 2011 Term Loan, with a syndicate of financial institutions as lenders. On May 4, 2015, the Company amended the 2011 Credit Facility to extend the maturity date of the 2011 Revolving Credit Facility by one year to March 9, 2017. The 2011 Term Loan matured on March 9, 2016 and the $229.7 million outstanding was repaid in full. Prior to its termination, the 2011 Term Loan most recently bore interest at either LIBOR plus the applicable margin between 2.00% and 3.00% or the base rate plus the applicable margin between 1.00% and 2.00%, based on the Company’s consolidated leverage ratio. The Company terminated the 2011 Revolving Credit Facility on February 15, 2017 and the $410.0 million outstanding was repaid in full. Prior to its termination, the 2011 Revolving Credit Facility most recently bore interest at either LIBOR plus the applicable margin between 4.00% and 5.00% or the base rate plus the applicable margin between 3.00% and 4.00%, based on the Company’s consolidated leverage ratio.

On February 15, 2017, the Company entered into a $1,450.0 million senior secured credit facility, or the 2017 Credit Facility, consisting of a $1,300.0 million term loan B, or the 2017 Term Loan B, and a $150.0 million revolving credit facility, or the 2017 Revolving Credit Facility, with a syndicate of financial institutions as lenders. The 2017 Revolving Credit Facility was to mature on February 15, 2022 and the 2017 Term Loan B was to mature on February 15, 2023. The 2017 Credit Facility was amended, effective March 16, 2018, to make certain technical amendments in connection with the offering of the 2024 Convertible Notes, as defined below. The Company terminated the 2017 Credit Facility on August 16, 2018 and the $1,178.1 million outstanding was repaid in full. Prior to its termination, the 2017 Term Loan B most recently bore interest at either the eurocurrency rate plus a margin of 5.50% or the base rate plus a margin of 4.50%, and the 2017 Revolving Credit Facility most recently bore interest at either the eurocurrency rate plus a margin of either 4.50% or 4.75% or the base rate plus a margin of either 3.50% or 3.75%, based on the Company’s consolidated leverage ratio. The eurocurrency rate was based on adjusted LIBOR and was subject to a floor of 0.75%. The base rate represented the highest of the Federal Funds Rate plus 0.50%, one-month adjusted LIBOR plus 1.00%, and the prime rate set by Credit Suisse, and was subject to a floor of 1.75%.

The 2017 Term Loan B was issued to the lenders at a 2% discount, or $26.0 million. The Company incurred approximately $22.6 million of debt issuance costs in connection with the 2017 Credit Facility. The debt issuance costs and the discount were recorded on the Company’s consolidated balance sheet and were being amortized over the life of the 2017 Credit Facility using the effective-interest method. The Company wrote off all remaining unamortized debt issuance costs and discount related to the 2017 Credit Facility upon its termination, which is included in the loss on extinguishment as described below.

On August 16, 2018, the Company entered into a new $1.25 billion senior secured credit facility, or the 2018 Credit Facility, consisting of a $250.0 million term loan A, or the 2018 Term Loan A, a $750.0 million term loan B, or the 2018 Term Loan B, and a $250.0 million revolving credit facility, or the 2018 Revolving Credit Facility. The 2018 Term Loan A and 2018 Revolving Credit Facility both mature on August 16, 2023 and the 2018 Term Loan B matures on August 18, 2025. However, the 2018 Term Loan A and 2018 Revolving Credit Facility will both mature on February 14, 2019 if the outstanding principal on the 2019 Convertible Notes, as defined below, exceeds $350.0 million and the Company exceeds certain leverage ratios on such date. In addition, the 2018 Term Loan B will mature on either: (i) May 16, 2019 if the outstanding principal on the 2019 Convertible Notes, as defined below, exceeds $350.0 million and the Company exceeds certain leverage ratios on such date; or (ii) December 15, 2023 if the outstanding principal on the 2024 Convertible Notes, as defined below, exceeds $350.0 million and the Company exceeds certain leverage ratios on such date. The Company did not exceed those certain leverage ratios as of February 14, 2019 and as such, the 2018 Term Loan A and 2018 Revolving Credit Facility will continue to mature on August 16, 2023. All obligations under the 2018 Credit Facility are unconditionally guaranteed by certain direct and indirect wholly-owned subsidiaries of Herbalife Nutrition Ltd. and secured by the equity interests of certain of Herbalife Nutrition Ltd.’s subsidiaries and substantially all of the assets of the domestic loan parties. Also on August 16, 2018, the Company issued $400 million aggregate principal amount of senior unsecured notes, or 2026 Notes as described below, and used the proceeds from the 2018 Credit Facility and the 2026 Notes to repay in full the $1,178.1 million outstanding under the 2017 Credit Facility. For accounting purposes, pursuant to FASB ASC Topic 470, Debt, or ASC 470, these transactions were accounted for as an extinguishment of the 2017 Credit Facility. The Company recognized a loss on extinguishment of $35.4 million as a result, which is recorded in other expense (income), net within the Company’s consolidated statement of income for the year ended December 31, 2018.

The 2018 Term Loan B was issued to the lenders at a 0.25% discount, or $1.9 million. The Company incurred approximately $11.7 million of debt issuance costs in connection with the 2018 Credit Facility. The discount and debt issuance costs are recorded on the Company’s consolidated balance sheet and are being amortized over the life of the 2018 Credit Facility using the effective-interest method.

Borrowings under both the 2018 Term Loan A and 2018 Revolving Credit Facility bear interest at either the eurocurrency rate plus a margin of 3.00% or the base rate plus a margin of 2.00%. Borrowings under the 2018 Term Loan B bear interest at either the eurocurrency rate plus a margin of 3.25% or the base rate plus a margin of 2.25%. The eurocurrency rate is based on adjusted LIBOR. The base rate represents the highest of the Federal Funds Rate plus 0.50%, one-month adjusted LIBOR plus 1.00%, and the prime rate quoted by The Wall Street Journal, and is subject to a floor of 1.00%. The Company is required to pay a commitment fee on the 2018 Revolving Credit Facility of 0.50% per annum on the undrawn portion of the 2018 Revolving Credit Facility. Interest is due at least quarterly on amounts outstanding under the 2018 Credit Facility.

The 2018 Credit Facility requires the Company to comply with a leverage ratio. The 2018 Credit Facility also contains affirmative and negative covenants customary for financings of this type, including, among other things, limitations or prohibitions on repurchasing common shares, declaring and paying dividends and other distributions, redeeming and repurchasing certain other indebtedness, loans and investments, additional indebtedness, liens, mergers, asset sales and transactions with affiliates. In addition, the 2018 Credit Facility contains customary events of default. As of December 31, 2018 and 2017, the Company was in compliance with its debt covenants under the 2018 Credit Facility and 2017 Credit Facility, respectively.

The 2018 Term Loan A and 2018 Term Loan B are payable in consecutive quarterly installments which began on December 31, 2018. In addition, beginning in 2020, the Company may be required to make mandatory prepayments towards the 2018 Term Loan B based on the Company’s consolidated leverage ratio and annual excess cash flows as defined under the terms of the 2018 Credit Facility. The Company is also permitted to make voluntary prepayments. On or prior to February 16, 2019, amounts voluntarily prepaid under the 2018 Term Loan A and 2018 Term Loan B will incur a prepayment premium of 1%; thereafter, amounts outstanding under the 2018 Term Loan A and 2018 Term Loan B may be voluntarily prepaid without premium or penalty, subject to customary breakage fees in connection with the prepayment of a eurocurrency loan. These prepayments, if any, will be applied against remaining quarterly installments owed under the 2018 Term Loan A and 2018 Term Loan B in order of maturity with the remaining principal due upon maturity, unless directed otherwise by the Company.

As of December 31, 2018 and 2017, the weighted-average interest rate for borrowings under the 2018 Credit Facility and 2017 Credit Facility was 6.80% and 6.79%, respectively.

During the year ended December 31, 2018, the Company borrowed an aggregate amount of $1,000.0 million under the 2018 Credit Facility and repaid a total amount of $1,231.9 million, including $5.0 million on amounts outstanding under the 2018 Credit Facility and $1,226.9 million to repay in full amounts outstanding under the 2017 Credit Facility. During the year ended December 31, 2017, the Company borrowed an aggregate amount of $1,300.0 million under the 2017 Credit Facility and repaid a total amount of $483.1 million, including $73.1 million on amounts outstanding under the 2017 Credit Facility and $410.0 million to repay in full amounts outstanding under the 2011 Credit Facility. During the year ended December 31, 2016, the Company borrowed an aggregate amount of $200.0 million and repaid a total amount of $429.7 million on amounts outstanding under the 2011 Credit Facility. As of December 31, 2018 and 2017, the U.S. dollar amount outstanding under the 2018 Credit Facility and 2017 Credit Facility was $995.0 million and $1,226.9 million, respectively. Of the $995.0 million outstanding under the 2018 Credit Facility as of December 31, 2018, $246.9 million was outstanding under the 2018 Term Loan A and $748.1 million was outstanding under the 2018 Term Loan B. Of the $1,226.9 million outstanding under the 2017 Credit Facility as of December 31, 2017, $1,226.9 million was outstanding under the 2017 Term Loan B. There were no borrowings outstanding under the 2018 Revolving Credit Facility and 2017 Revolving Credit Facility as of December 31, 2018 and 2017, respectively. There were no outstanding foreign currency borrowings as of December 31, 2018 and 2017 under the 2018 Credit Facility and 2017 Credit Facility, respectively.

During the year ended December 31, 2018, the Company recognized $83.6 million of interest expense relating to the 2018 Credit Facility and 2017 Credit Facility, which included $2.9 million relating to non-cash interest expense relating to the debt discount and $3.2 million relating to amortization of debt issuance costs. During the year ended December 31, 2017, the Company recognized $87.0 million of interest expense relating to the 2017 Credit Facility and 2011 Credit Facility, which included $4.2 million relating to non-cash interest expense relating to the debt discount and $4.4 million relating to amortization of debt issuance costs. During the year ended December 31, 2016, the Company recognized $24.1 million of interest expense relating to the 2011 Credit Facility, which included $4.1 million relating to amortization of debt issuance costs.

The fair value of the outstanding borrowings on the 2018 Term Loan A is determined by utilizing over-the-counter market quotes for similar instruments, which are considered Level 2 inputs as described in Note 12, Fair Value Measurements. As of December 31, 2018, the carrying value of the 2018 Term Loan A was $245.4 million and the fair value was approximately $240.7 million. The fair values of the outstanding borrowings under the 2018 Term Loan B and the 2017 Term Loan B are determined by utilizing over-the-counter market quotes, which are considered Level 2 inputs as described in Note 12, Fair Value Measurements. As of December 31, 2018 and 2017, the carrying amount of the 2018 Term Loan B and 2017 Term Loan B was $738.2 million and $1,190.2 million, respectively, and the fair value was approximately $729.3 million and $1,226.1 million, respectively.

Convertible Senior Notes due 2019

During February 2014, the Company initially issued $1 billion aggregate principal amount of convertible senior notes, or the 2019 Convertible Notes, in a private offering to qualified institutional buyers, pursuant to Rule 144A under the Securities Act of 1933, as amended. The Company granted an option to the initial purchasers to purchase up to an additional $150 million aggregate principal amount of 2019 Convertible Notes which was subsequently exercised in full during February 2014, resulting in a total issuance of $1.15 billion aggregate principal amount of 2019 Convertible Notes. The 2019 Convertible Notes are senior unsecured obligations which rank effectively subordinate to any of the Company’s existing and future secured indebtedness, including amounts outstanding under the 2018 Credit Facility, to the extent of the value of the assets securing such indebtedness. The 2019 Convertible Notes pay interest at a rate of 2.00% per annum payable semiannually in arrears on February 15 and August 15 of each year, beginning on August 15, 2014. The 2019 Convertible Notes mature on August 15, 2019, unless earlier repurchased or converted. The Company may not redeem the 2019 Convertible Notes prior to their stated maturity date. Holders of the 2019 Convertible Notes may convert their notes at their option under the following circumstances: (i) during any calendar quarter commencing after the calendar quarter ending March 31, 2014, if the last reported sale price of the Company’s common shares for at least 20 trading days (whether or not consecutive) in a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter exceeds 130% of the conversion price for the 2019 Convertible Notes on each applicable trading day; (ii) during the five business-day period immediately after any five consecutive trading day period, or the measurement period, in which the trading price per $1,000 principal amount of 2019 Convertible Notes for each trading day of that measurement period was less than 98% of the product of the last reported sale price of the Company’s common shares and the conversion rate for the 2019 Convertible Notes for each such day; or (iii) upon the occurrence of specified corporate events. On and after May 15, 2019, holders may convert their 2019 Convertible Notes at any time, regardless of the foregoing circumstances. Upon conversion, the 2019 Convertible Notes will be settled in cash and, if applicable, the Company’s common shares, based on the applicable conversion rate at such time. The 2019 Convertible Notes had an initial conversion rate of 23.1816 common shares per $1,000 principal amount of the 2019 Convertible Notes, or an initial conversion price of approximately $43.14 per common share, based on the retroactive adjustment due to the Company’s two-for-one stock split described in Note 2, Basis of Presentation. The conversion rate is subject to adjustment upon the occurrence of certain events and was 23.2245 common shares per $1,000 principal amount of the 2019 Convertible Notes, or a conversion price of approximately $43.06 per common share, as of December 31, 2018. As of December 31, 2018, the if-converted value of the 2019 Convertible Notes exceeded their outstanding principal amount by $249.1 million since the closing price of the Company's common shares was $58.95 compared to the conversion price of $43.06. The Company has entered into capped call transactions with respect to its common shares, which are expected generally to reduce the potential dilution upon conversion of the 2019 Convertible Notes in the event that the market price of the common shares is greater than the strike price of the capped call transactions. See Note 8, Shareholders’ Deficit, for additional discussion on the capped call transactions.

During the fourth quarter of 2018, the last reported sale price of the Company’s common shares exceeded 130% of the conversion price for the 2019 Convertible Notes for at least 20 trading days in the period of 30 consecutive trading days ending on, and including, the last trading day of the quarter. As such, the 2019 Convertible Notes will be convertible at the holders’ option during the first quarter of 2019. The Company will reclassify the difference between the aggregate principal amount and the carrying value of the 2019 Convertible Notes of approximately $18.6 million from additional paid-in capital to temporary equity on its consolidated balance sheet on January 1, 2019.

The Company incurred approximately $26.6 million of issuance costs during the first quarter of 2014 relating to the issuance of the 2019 Convertible Notes. Of the $26.6 million issuance costs incurred, $21.5 million and $5.1 million were recorded as debt issuance costs and additional paid-in capital, respectively, in proportion to the allocation of the proceeds of the 2019 Convertible Notes. The $21.5 million of debt issuance costs recorded on the Company’s consolidated balance sheet are being amortized over the contractual term of the 2019 Convertible Notes using the effective-interest method.

During February 2014, the $1.15 billion aggregate principal amount of the 2019 Convertible Notes were initially allocated between long-term debt, or liability component, and additional paid-in capital, or equity component, within the Company’s consolidated balance sheet at $930.9 million and $219.1 million, respectively. The liability component was measured using the nonconvertible debt interest rate. The carrying amount of the equity component representing the conversion option was determined by deducting the fair value of the liability component from the face value of the 2019 Convertible Notes as a whole. Since the Company must still settle these 2019 Convertible Notes at face value at or prior to maturity, this liability component will be accreted up to its face value resulting in additional non-cash interest expense being recognized within the Company’s consolidated statements of income while the 2019 Convertible Notes remain outstanding. The effective-interest rate on the 2019 Convertible Notes is approximately 6.2% per annum. The equity component is not remeasured as long as it continues to meet the conditions for equity classification.

During March 2018, the Company issued $550 million aggregate principal amount of new convertible senior notes due 2024, or 2024 Convertible Notes as described below, and subsequently used the proceeds, along with cash on hand, to repurchase $475.0 million of its existing 2019 Convertible Notes from a limited number of holders in privately negotiated transactions for an aggregate purchase price of $583.5 million, which included $1.0 million of accrued interest. For accounting purposes, pursuant to ASC 470, Debt, these transactions were accounted for as an extinguishment of 2019 Convertible Notes and an issuance of new 2024 Convertible Notes. The Company allocated the purchase price between the fair value of the liability component and the equity component of the 2019 Convertible Notes at $459.4 million and $123.0 million, respectively. As a result, the Company recognized $446.4 million as a reduction to long-term debt representing the carrying value of the liability component and $123.0 million as a reduction to additional paid-in capital representing the equity component of the repurchased 2019 Convertible Notes. The $13.1 million difference between the fair value and carrying value of the liability component of the repurchased 2019 Convertible Notes was recognized as a loss on extinguishment of debt as a result of the transaction and is recorded in other expense (income), net within the Company’s consolidated statement of income. The accounting impact of the new 2024 Convertible Notes is described in further detail below.

As of December 31, 2018, the remaining outstanding principal on the 2019 Convertible Notes was $675.0 million, the unamortized debt discount and debt issuance costs were $18.6 million, and the carrying amount of the liability component was $656.4 million, which was recorded to Current portion of long-term debt within the Company’s consolidated balance sheet. As of December 31, 2017, the outstanding principal on the 2019 Convertible Notes was $1.15 billion, the unamortized debt discount and debt issuance costs were $80.0 million, and the carrying amount of the liability component was $1,070.0 million, which was recorded to Long-term debt within the Company’s consolidated balance sheet. The fair value of the liability component relating to the 2019 Convertible Notes was approximately $662.1 million and $1,066.0 million as of December 31, 2018 and 2017, respectively.

During the years ended December 31, 2018, 2017, and 2016, the Company recognized $48.5 million, $68.2 million, and $65.3 million, respectively, of interest expense relating to the 2019 Convertible Notes, which included $29.8 million, $41.2 million, and $38.6 million, respectively, relating to non-cash interest expense relating to the debt discount and $2.9 million, $4.0 million, and $3.8 million, respectively, relating to amortization of debt issuance costs.

In conjunction with the issuance of the 2019 Convertible Notes, during February 2014, the Company paid approximately $685.8 million to enter into prepaid forward share repurchase transactions, or the Forward Transactions, with certain financial institutions, and paid approximately $123.8 million to enter into capped call transactions with respect to its common shares, or the Capped Call Transactions, with certain financial institutions. Subsequently, in conjunction with the repurchase of a portion of the 2019 Convertible Notes, during March 2018, the Company entered into agreements with the option counterparties to the Capped Call Transactions to terminate a portion of such existing transactions. See Note 8, Shareholders’ Deficit, for additional discussion on the Forward Transactions and Capped Call Transactions entered into in conjunction with the issuance of these 2019 Convertible Notes.

Convertible Senior Notes due 2024

During March 2018, the Company issued $550 million aggregate principal amount of convertible senior notes, or the 2024 Convertible Notes, in a private offering to qualified institutional buyers, pursuant to Rule 144A under the Securities Act of 1933, as amended. The 2024 Convertible Notes are senior unsecured obligations which rank effectively subordinate to any of the Company’s existing and future secured indebtedness, including amounts outstanding under the 2018 Credit Facility, to the extent of the value of the assets securing such indebtedness. The 2024 Convertible Notes pay interest at a rate of 2.625% per annum payable semiannually in arrears on March 15 and September 15 of each year, beginning on September 15, 2018. The 2024 Convertible Notes mature on March 15, 2024, unless redeemed, repurchased or converted in accordance with their terms prior to such date. Holders of the 2024 Convertible Notes may convert their notes at their option under the following circumstances: (i) during any calendar quarter commencing after the calendar quarter ending June 30, 2018, if the last reported sale price of the Company’s common shares for at least 20 trading days (whether or not consecutive) in a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter exceeds 130% of the conversion price for the 2024 Convertible Notes on each applicable trading day; (ii) during the five business-day period immediately after any five consecutive trading day period, or the measurement period, in which the trading price per $1,000 principal amount of 2024 Convertible Notes for each trading day of that measurement period was less than 98% of the product of the last reported sale price of the Company’s common shares and the conversion rate for the 2024 Convertible Notes for each such day; (iii) if the Company calls the 2024 Convertible Notes for redemption; or (iv) upon the occurrence of specified corporate events. On and after December 15, 2023, holders may convert their 2024 Convertible Notes at any time, regardless of the foregoing circumstances. Upon conversion, the 2024 Convertible Notes will be settled, at the Company’s election, in cash, the Company’s common shares, or a combination thereof, based on the applicable conversion rate at such time. The 2024 Convertible Notes had an initial conversion rate of 16.0056 common shares per $1,000 principal amount of the 2024 Convertible Notes, or an initial conversion price of approximately $62.48 per common share, based on the retroactive adjustment due to the Company’s two-for-one stock split described in Note 2, Basis of Presentation. The conversion rate is subject to adjustment upon the occurrence of certain events and was 16.0352 common shares per $1,000 principal amount of the 2024 Convertible Notes, or a conversion price of approximately $62.36 per common share, as of December 31, 2018.

The Company incurred approximately $12.9 million of issuance costs during the first quarter of 2018 relating to the issuance of the 2024 Convertible Notes. Of the $12.9 million issuance costs incurred, $9.6 million and $3.3 million were recorded as debt issuance costs and additional paid-in capital, respectively, in proportion to the allocation of the proceeds of the 2024 Convertible Notes. The $9.6 million of debt issuance costs, which was recorded as an additional debt discount on the Company’s consolidated balance sheet, are being amortized over the contractual term of the 2024 Convertible Notes using the effective-interest method.

During March 2018, the $550 million aggregate principal amount of the 2024 Convertible Notes were initially allocated between long-term debt, or liability component, and additional paid-in-capital, or equity component, within the Company’s consolidated balance sheet at $410.1 million and $139.9 million, respectively. The liability component was measured using the nonconvertible debt interest rate. The carrying amount of the equity component representing the conversion option was determined by deducting the fair value of the liability component from the face value of the 2024 Convertible Notes as a whole. Since the Company must still settle these 2024 Convertible Notes at face value at or prior to maturity, this liability component will be accreted up to its face value resulting in additional non-cash interest expense being recognized within the Company’s consolidated statements of income while the 2024 Convertible Notes remain outstanding. The effective-interest rate on the 2024 Convertible Notes is approximately 8.4% per annum. The equity component is not remeasured as long as it continues to meet the conditions for equity classification.

As of December 31, 2018, the outstanding principal on the 2024 Convertible Notes was $550.0 million, the unamortized debt discount and debt issuance costs were $134.0 million, and the carrying amount of the liability component was $416.0 million, which was recorded to Long-term debt within the Company’s consolidated balance sheet. The fair value of the liability component relating to the 2024 Convertible Notes was approximately $448.1 million as of December 31, 2018.

During the year ended December 31, 2018, the Company recognized $26.6 million of interest expense relating to the 2024 Convertible Notes, which included $14.5 million relating to non-cash interest expense relating to the debt discount and $1.0 million relating to amortization of debt issuance costs.

Senior Notes due 2026

During August 2018, the Company issued $400 million aggregate principal amount of senior notes, or the 2026 Notes, in a private offering in the United States to qualified institutional buyers, pursuant to Rule 144A under the Securities Act of 1933, as amended, and outside the United States pursuant to Regulation S under the Securities Act of 1933, as amended. The 2026 Notes are senior unsecured obligations which rank effectively subordinate to any of the Company’s existing and future secured indebtedness, including amounts outstanding under the 2018 Credit Facility, to the extent of the value of the assets securing such indebtedness. The 2026 Notes pay interest at a rate of 7.250% per annum payable semiannually in arrears on February 15 and August 15 of each year, beginning on February 15, 2019. The 2026 Notes mature on August 15, 2026.

At any time prior to August 15, 2021, the Company may redeem all or part of the 2026 Notes at a redemption price equal to 100% of their principal amount, plus a “make whole” premium as of the redemption date, and accrued and unpaid interest to the redemption date. In addition, at any time prior to August 15, 2021, the Company may redeem up to 40% of the aggregate principal amount of the 2026 Notes with the proceeds of one or more equity offerings, at a redemption price equal to 107.250%, plus accrued and unpaid interest. Furthermore, at any time on or after August 15, 2021, the Company may redeem all or part of the 2026 Notes at the following redemption prices, expressed as percentages of principal amount, plus accrued and unpaid interest thereon to the redemption date, if redeemed during the twelve-month period beginning on August 15 of the years indicated below:

	Percentage
2021		103.625	%
2022		101.813	%
2023 and thereafter		100.000	%

The 2026 Notes contain customary negative covenants, including, among other things, limitations or prohibitions on restricted payments, incurrence of additional indebtedness, liens, mergers, asset sales and transactions with affiliates. In addition, the 2026 Notes contain customary events of default.

The Company incurred approximately $5.4 million of issuance costs during the third quarter of 2018 relating to the issuance of the 2026 Notes. The $5.4 million of debt issuance costs, which was recorded as a debt discount on the Company’s consolidated balance sheet, are being amortized over the contractual term of the 2026 Notes using the effective-interest method.

As of December 31, 2018, the outstanding principal on the 2026 Notes was $400.0 million, the unamortized debt issuance costs were $5.2 million, and the carrying amount was $394.8 million, which was recorded to long-term debt within the Company’s consolidated balance sheet. The fair value of the 2026 Notes was approximately $394.6 million as of December 31, 2018 and was determined by utilizing over-the-counter market quotes and yield curves, which are considered Level 2 inputs as defined in Note 13, Fair Value Measurements.

During the year ended December 31, 2018, the Company recognized $11.1 million of interest expense relating to the 2026 Notes, which included $0.2 million relating to amortization of debt issuance costs.

Valuation of 2019 Convertible Notes and 2024 Convertible Notes – Level 2 and Level 3 Inputs

In order to determine the initial value of the 2019 Convertible Notes and the 2024 Convertible Notes, the Company determined the fair value of the liability component of the 2019 Convertible Notes and the 2024 Convertible Notes using two valuation methods. The Company reviewed market data that was available for publicly traded, senior, unsecured nonconvertible corporate bonds issued by companies with similar credit ratings. Assumptions used in the estimate represent what market participants would use in pricing the liability component, including market yields and credit standing to develop the straight debt yield estimate. The Company also used a lattice model, which included inputs such as stock price, the Convertible Note trading price, volatility and dividend yield to estimate the straight debt yield. The Company combined the results of the two valuation methods to determine the fair value of the liability component of the 2019 Convertible Notes and the 2024 Convertible Notes. Most of these inputs are primarily considered Level 2 and Level 3 inputs. The Company used similar valuation approaches to determine the subsequent fair value of the liability component only for disclosure purposes, which includes using a lattice model and (1) reviewing market data relating to its 2026 Notes and comparable yield curves to determine its straight debt yield estimate, or (2) reviewing market data relating to publicly traded, senior, unsecured nonconvertible corporate bonds issued by companies with similar credit ratings in order to determine its straight debt yield estimate.

Total Debt

The Company’s total interest expense was $181.0 million, $160.8 million, and $99.3 million, for the years ended December 31, 2018, 2017, and 2016, respectively, which was recognized within its consolidated statements of income.

As of December 31, 2018, annual scheduled principal payments of debt were as follows:

Thereafter		1,660.6
Total	$	2,622.9

Certain vendors and government agencies may require letters of credit or similar guaranteeing arrangements to be issued or executed. As of December 31, 2018, the Company had $38.2 million of issued but undrawn letters of credit or similar arrangements, which included the Mexico Value Added Tax, or VAT, related surety bonds described in Note 7, Contingencies.

Employee Compensation Plans

6. Employee Compensation Plans

In the United States, the Company maintains a profit sharing plan pursuant to Sections 401(a) and (k) of the Internal Revenue Code of 1986, as amended, or the Code. The plan is available to substantially all employees who meet the length of service requirements. The Company’s contribution expense relating to this profit sharing plan was $5.7 million, $4.8 million, and $4.8 million during the years ended December 31, 2018, 2017, and 2016, respectively.

The Company has employees in international countries that are covered by various deferred compensation plans. These plans are administered based upon the legal requirements in the countries in which they are established. The Company’s compensation expenses relating to these plans were $6.6 million, $6.4 million, and $5.8 million for the years ended December 31, 2018, 2017, and 2016, respectively.

The Company has non-qualified deferred compensation plans for select groups of management: the Herbalife Management Deferred Compensation Plan and the Herbalife Senior Executive Deferred Compensation Plan. The matching contribution was 3.5% of a participant’s annual base salary in excess of the Qualified Plan annual compensation limit and the amount by which deferrals reduce 401(k) eligible pay below the IRS limit.

Each participant in either of the non-qualified deferred compensation plans discussed above has, at all times, a fully vested and non-forfeitable interest in each year’s contribution, including interest credited thereto, and in any Company matching contributions, if applicable. In connection with a participant’s election to defer an annual deferral amount, the participant may also elect to receive a short-term payout, equal to the annual deferral amount plus interest. Such amount is payable in five or more years from the first day of the year in which the annual deferral amount is actually deferred.

The total for the two non-qualified deferred compensation plans, excluding participant contributions, was a benefit of $2.7 million for the year ended December 31, 2018 and an expense of $6.7 million, and $3.6 million for the years ended December 31, 2017 and 2016, respectively. The total long-term deferred compensation liability under the two deferred compensation plans was $51.3 million and $58.1 million as of December 31, 2018 and 2017, respectively, and is included in Other non-current liabilities within the Company’s consolidated balance sheets.

The deferred compensation plans are unfunded and their benefits are paid from the general assets of the Company, except that the Company has contributed to a “rabbi trust” whose assets will be used to pay the benefits if the Company remains solvent, but can be reached by the Company’s creditors if the Company becomes insolvent. The value of the assets in the “rabbi trust” was $31.2 million and $33.6 million as of December 31, 2018 and 2017, respectively, and is included in Other assets within the Company’s consolidated balance sheets.

Commitments And Contingencies Disclosure [Abstract]

Contingencies

7. Contingencies

The Company is from time to time engaged in routine litigation. The Company regularly reviews all pending litigation matters in which it is involved and establishes reserves deemed appropriate by management for these litigation matters when a probable loss estimate can be made.

The matters described in this Note may take several years to resolve. While the Company believes it has meritorious defenses, it cannot be sure of their ultimate resolution. Although the Company may reserve amounts for certain matters that the Company believes represent the most likely outcome of the resolution of these related disputes, if the Company is incorrect in its assessment, the Company may have to record additional expenses, when it becomes probable that an increased potential liability is warranted.

Tax Matters

On May 7, 2010, the Company received an assessment from the Mexican Tax Administration Service in an amount equivalent to approximately $58.3 million, translated at the December 31, 2018 spot rate, for various items, the majority of which was VAT allegedly owed on certain of the Company’s products imported into Mexico during the years 2005 and 2006. This assessment is subject to interest and inflationary adjustments. On July 8, 2010, the Company initiated a formal administrative appeal process. On May 13, 2011, the Mexican Tax Administration Service issued a resolution on the Company’s administrative appeal. The resolution nullified the assessment. Since the Mexican Tax Administration Service can further review the tax audit findings and re-issue some or all of the original assessment, the Company commenced litigation in the Tax Court of Mexico in August 2011 to dispute the assertions made by the Mexican Tax Administration Service in the case. The Company received notification on February 6, 2015 that the Tax Court of Mexico nullified substantially all of the assessment. On March 18, 2015, the Mexican Tax Administration Service filed an appeal against the verdict with the Circuit Court. On August 27, 2015, the Circuit Court remanded the case back to the Tax Court of Mexico to reconsider a portion of the procedural decision that was adverse to the Mexican Tax Administration Service. The Company received notification on March 18, 2016 that the Tax Court of Mexico nullified a portion of the assessment and upheld a portion of the original assessment. On August 25, 2016, the Company filed a further appeal of this decision to the Circuit Court. On April 6, 2017, the Circuit Court issued a verdict with the Company prevailing on some lesser issues and the Tax Administration Service prevailing on the core issue. On May 11, 2017, the Company filed a further appeal to the Supreme Court of Mexico. On June 14, 2017, the Supreme Court of Mexico agreed to hear the appeal. On December 14, 2018, the Supreme Court of Mexico held a public hearing at which a decision was adopted in favor of the Company, revoking previous court rulings and remanding the case back to the trial court so the assessment could be nullified. The remand process administered by the Federal Tax Court concluded in favor of the Company, nullifying the VAT and Excise Tax assessment for fiscal years 2005 and 2006. The Company has not recognized a loss as the case was concluded in the Company’s favor.

The Mexican Tax Administration Service commenced audits of the Company’s Mexican subsidiaries for the period from January to September 2007 and on May 10, 2013, the Company received an assessment of approximately $14.9 million, translated at the December 31, 2018 spot rate, related to that period. This assessment is subject to interest and inflationary adjustments. On July 11, 2013, the Company filed an administrative appeal disputing the assessment. On September 22, 2014, the Mexican Tax Administration Service denied the Company’s administrative appeal. The Company commenced litigation in the Tax Court of Mexico in November 2014 to dispute the assertions made by the Mexican Tax Administration Service in the case. On January 16, 2018, the Tax Court of Mexico issued a verdict upholding the assessment issued by the Mexican Tax Administration Service. On April 16, 2018, the Company filed an appeal of this verdict, and litigation is ongoing. The Company has not recognized a loss as the Company does not believe a loss is probable. The Company issued a surety bond in the amount of $18.4 million, translated at the December 31, 2018 spot rate, through an insurance company to guarantee payment of the tax assessment as required while the Company pursues an appeal of the assessment, and the surety bond remained effective as of December 31, 2018.

The Mexican Tax Administration Service has delayed processing VAT refunds for companies operating in Mexico and the Company believes that the process for its Mexico subsidiary to receive VAT refunds may be delayed. As of December 31, 2018, the Company had $33.1 million of Mexico VAT related assets, of which $24.3 million was within non-current other assets and $8.8 million was within prepaid expenses and other current assets on its consolidated balance sheet. This amount relates to VAT payments made over various periods and the Company believes these amounts are recoverable by refund or they may be applied against certain future tax liabilities. Effective January 1, 2019, a tax reform law changed the rules concerning possible use of VAT assets, specifically providing that, for VAT balances generated after December 31, 2018, those balances could not be offset against taxes other than VAT obligations currently due. The Company has not recognized any losses related to these VAT related assets as the Company does not believe a loss is probable.

With respect to these Mexican matters, the Company is currently unable to reasonably estimate a possible loss or range of loss that could result from an unfavorable outcome if an assessment was re-issued or any additional assessments were to be issued for these or other periods. The Company believes that it has meritorious defenses if an assessment is re-issued or would have meritorious defenses if any additional assessment is issued.

The Company received a tax assessment in September 2009 from the Federal Revenue Office of Brazil related to withholding/contributions based on payments to the Company’s Members during 2004. On March 6, 2014, the Company was notified of a similar audit of the 2011 year, and in January 2016, the Company received a tax assessment related to contributions based on payments to the Company’s Members during 2011. The Company received a favorable decision from the Administrative Council of Tax Appeals for the 2004 and 2011 cases in September 2018. On October 31, 2018 and November 19, 2018, the government filed appeals relating to the 2004 and 2011 cases for which the combined total is $6.4 million, translated at the December 31, 2018 spot rate. The Company has not accrued a loss for the majority of the assessments because the Company does not believe a loss is probable. The Company is currently unable to reasonably estimate the amount of the loss that may result from an unfavorable outcome if additional assessments for other periods were to be issued.

The Company is under examination in several Brazilian states related to ICMS and ICMS-ST taxation. Some of these examinations have resulted in assessments for underpaid tax that the Company has appealed. The State of São Paulo has audited the Company for the 2013 and 2014 tax years. During July 2016, for the State of São Paulo, the Company received an assessment in the aggregate amount of approximately $41.5 million, translated at the December 31, 2018 spot rate, relating to various ICMS issues for its 2013 tax year. In August 2016, the Company filed a first-level administrative appeal which was denied in February 2017. The Company filed a further appeal on March 9, 2017. On March 20, 2018, the Court held a hearing and a verdict is currently pending. During August 2017, for the state of São Paulo, the Company received an assessment in the aggregate amount of approximately $15.4 million, translated at the December 31, 2018 spot rate, relating to various ICMS issues for its 2014 tax year. In September 2017, the Company filed a first-level administrative appeal for the 2014 tax year. During September 2018, for the State of Rio de Janeiro, the Company received an assessment in the aggregate amount of approximately $9.1 million, translated at the December 31, 2018 spot rate, relating to various ICMS-ST issues for its 2016 and 2017 tax years. On November 8, 2018, the Company filed a first-level administrative appeal. The Company has also received other ICMS tax assessments in Brazil. During the fourth quarter of 2015, the Company filed appeals with state judicial courts against three of the assessments. The Company had issued surety bonds in the aggregate amount of $11.2 million, translated at the December 31, 2018 spot rate, to guarantee payment of some of the tax assessments as required while the Company pursues the appeals. In addition, the Company has received several ICMS tax assessments in the aggregate amount of $6.3 million, translated at the December 31, 2018 spot rate, from several other Brazilian states where surety bonds have not been issued. Litigation in all these cases is currently ongoing. The Company has not recognized a loss as the Company does not believe a loss is probable.

The Company has received various tax assessments in multiple states in India for multiple years from the Indian VAT authorities in an amount equivalent to approximately $9.0 million, translated at the December 31, 2018 spot rate. These assessments are for underpaid VAT. The Company is litigating these cases at the tax administrative level and the tax tribunal levels as it believes it has meritorious defenses. The Company has not recognized a loss as it does not believe a loss is probable.

The Korea Customs Service audited the importation activities of Herbalife Korea for the period January 2011 through May 2013. The total assessment for the audit period is $31.8 million, translated at the December 31, 2018 spot rate. The Company has paid the assessment and has recognized these payments within other assets on its consolidated balance sheet. The Company lodged a first-level administrative appeal, which was denied on October 21, 2016. On January 31, 2017, the Company filed a further appeal to the National Tax Tribunal of Korea. In November 2018, the Company received an unfavorable decision from the National Tax Tribunal of Korea. In February 2019, the Company submitted an appeal to the Seoul Administrative Court. The Company disagrees with the assertions made in the assessments, as well as the calculation methodology used in the assessments. The Company has not recognized a loss as the Company does not believe a loss is probable.

During the course of 2016, the Company received various questions from the Greek Social Security Agency and on December 29, 2016, the Greek Social Security Agency issued an assessment with respect to Social Security Contributions on Member earnings for the 2006 year. For Social Security issues, the statute of limitations is open for 2007 and later years in Greece. Despite the assessment amount being immaterial, the Company could receive similar assessments covering other years. The Company continues to litigate the assessment. The Company has not recognized a loss as it does not believe a loss is probable. The Company is currently unable to reasonably estimate the amount of the loss that may result from an unfavorable outcome if additional assessments for other periods were to be issued.

The Italian tax authorities audited the Company for the periods 2014 and 2015. The Company has responded to the various points relating to income tax and non-income tax matters initially raised by the tax authorities to date. The Italian tax authorities are discussing certain of its preliminary findings with the Company. It is possible that the Company could receive a final assessment from the Italian authorities after these discussions. The Company believes that it has adequately accrued for income tax matters that are known to date. In regards to non-income tax matters, the Company has not recognized a loss as it does not believe a loss is probable. The Company believes that it has meritorious defenses if a formal assessment is issued by the Italian tax authorities. The Company is currently unable to reasonably estimate the amount of loss that may result from an unfavorable outcome if a formal assessment is issued by the Italian tax authorities.

During March 2018, the Chinese Customs Service began an audit of the Company’s Chinese importations covering the periods 2015 through 2017. The Company has responded to the initial questions from the Customs Service and the audit is ongoing. The Company is currently unable to determine the outcome of this audit and reasonably estimate the amount of loss if an assessment is issued.

U.S. Federal Trade Commission Consent Order

On July 15, 2016, the Company and the Federal Trade Commission, or the FTC, entered into a proposed Stipulation to Entry of Order for Permanent Injunction and Monetary Judgment, or the Consent Order. The Consent Order was lodged with the U.S. District Court for the Central District of California on July 15, 2016 and became effective on July 25, 2016, or the Effective Date. The Consent Order resolved the FTC’s multi-year investigation of the Company.

Pursuant to the Consent Order, under which the Company neither admitted nor denied the FTC’s allegations (except as to the Court having jurisdiction over the matter), the Company made, through its wholly-owned subsidiary Herbalife International of America, Inc., a $200 million payment to the FTC. Additionally, the Company implemented and continues to enhance certain existing procedures in the U.S. Among other requirements, the Consent Order requires the Company to categorize all existing and future Members in the U.S. as either “preferred members” – who are simply consumers who only wish to purchase products for their own household use, or “distributors” – who are Members who wish to resell some products or build a sales organization. The Company also agreed to compensate distributors on eligible U.S. sales within their downline organization, which include purchases by preferred members, purchases by a distributor for his or her personal consumption within allowable limits and sales of product by a distributor to his or her customers. The Consent Order also imposes restrictions on a distributor’s ability to open Nutrition Clubs in the United States. The Consent Order subjects the Company to certain audits by an independent compliance auditor for a period of seven years; imposes requirements on the Company regarding compliance certification and record creation and maintenance; and prohibits the Company, its affiliates and its distributors from making misrepresentations and misleading claims regarding, among other things, income and lavish lifestyles. The FTC and the independent compliance auditor have the right to inspect Company records and request additional compliance reports for purposes of conducting audits pursuant to the Consent Order. In September 2016, the Company and the FTC mutually selected Affiliated Monitors, Inc. to serve as the independent compliance auditor. The Company continues to monitor the impact of the Consent Order and, while the Company currently does not expect the settlement to have a long-term and materially adverse impact on its business and its Member base, the Company’s business and its Member base, particularly in the United States, may be negatively impacted. If the Company is unable to comply with the Consent Order then this could result in a material and adverse impact to the Company’s results of operations and financial condition.

Other Matters

As a marketer of foods, dietary and nutritional supplements, and other products that are ingested by consumers or applied to their bodies, the Company has been and is currently subjected to various product liability claims. The effects of these claims to date have not been material to the Company. The Company currently maintains product liability insurance with an annual deductible of $12.5 million.

As previously disclosed, the SEC and the Department of Justice (“DOJ”) have been conducting an investigation into the Company’s compliance with the Foreign Corrupt Practices Act (“FCPA”) in China, which is mainly focused on the Company’s China external affairs expenditures relating to its China business activities and the adequacy of and compliance with the Company’s internal controls relating to such expenditures. This investigation is proceeding, with the government continuing to request documents and other information relating to these matters. The Company is conducting its own review and has taken remedial and improvement measures based upon this review, including but not limited to replacement of a number of employees and enhancements of Company policies and procedures in China. The Company is continuing to cooperate and engage in discussions with the SEC and DOJ. Although a likely outcome could include a resolution or government action, the Company cannot predict the eventual scope, duration, or outcome of the government investigation at this time, including potential monetary payments, injunctions, or other relief, the results of which may be materially adverse to the Company, its financial condition, its results of operations, and its operations. At the present time, the Company is unable to reasonably estimate the amount of loss relating to this matter.

The SEC has also requested from the Company documents and other information relating to the Company’s disclosures regarding its marketing plan in China. While the Company believes this SEC investigation is nearing conclusion, and although a likely outcome could include a resolution or enforcement action, the Company cannot predict the eventual scope, duration, or outcome of this investigation at this time. The possible range of outcomes includes discussions leading to a settlement which could include a monetary payment and other relief, the filing by the SEC of a civil complaint or administrative action, or the closure of this matter without action. At the present time, the Company is unable to reasonably estimate the amount of loss relating to this matter.

On September 18, 2017, the Company and certain of its subsidiaries and Members were named as defendants in a purported class action lawsuit, titled Rodgers, et al. v Herbalife Ltd., et al. and filed in the U.S. District Court for the Southern District of Florida, which alleges violations of Florida’s Deceptive and Unfair Trade Practices statute and federal Racketeer Influenced and Corrupt Organizations statutes, unjust enrichment, and negligent misrepresentation. On August 23, 2018, the Court issued an order transferring the action to the U.S. District Court for the Central District of California as to four of the putative class plaintiffs and ordering the remaining four plaintiffs to arbitration, thereby terminating the Company defendants from the Florida action. The plaintiffs seek damages in an unspecified amount. The Company believes the lawsuit is without merit and will vigorously defend itself against the claims in the lawsuit.

In September 2017, one of the Company’s warehouses located in Mexico sustained flooding which damaged certain inventory stored within the warehouse. The Company maintains insurance coverage with third-party carriers on the affected property. As of December 31, 2018, the Company has recorded a loss relating to the damaged inventory and has recognized a combined equal and offsetting receivable and cash relating to the insurance recoveries. This event did not have a material negative impact on the Company’s Mexico operations or its consolidated financial statements.

Equity [Abstract]

Shareholders' Deficit

8. Shareholders’ Deficit

The Company had 142.8 million, 164.7 million, and 186.3 million common shares outstanding as of December 31, 2018, 2017, and 2016, respectively. In December 2004, the Company authorized 7.5 million preference shares at $0.002 par value. The 7.5 million authorized preference shares remained unissued as of December 31, 2018. Preference shares may be issued from time to time in one or more series, each of such series to have such voting powers (full or limited or without voting powers), designations, preferences and relative, participating, optional or other special rights and qualifications, limitations or restrictions as determined by the Company’s board of directors.

Dividends

On April 28, 2014, the Company announced that its board of directors approved terminating its quarterly cash dividend and instead utilizing the cash to repurchase additional common shares. The declaration of future dividends is subject to the discretion of the Company’s board of directors and will depend upon various factors, including its earnings, financial condition, Herbalife Nutrition Ltd.’s available distributable reserves under Cayman Islands law, restrictions imposed by the 2018 Credit Facility and the terms of any other indebtedness that may be outstanding, cash requirements, future prospects and other factors deemed relevant by its board of directors. The Company did not pay or declare any dividends during the fiscal years ended December 31, 2018, 2017, and 2016.

Share Repurchases

On October 30, 2018, the Company’s board of directors authorized a new five-year $1.5 billion share repurchase program that will expire on October 30, 2023, which replaced the Company’s prior share repurchase authorization that was set to expire on February 21, 2020 and had approximately $113.3 million of remaining authorized capacity when it was replaced. This share repurchase program allows the Company, which includes an indirect wholly-owned subsidiary of Herbalife Nutrition Ltd., to repurchase the Company’s common shares at such times and prices as determined by management, as market conditions warrant, and to the extent Herbalife Nutrition Ltd.’s distributable reserves are available under Cayman Islands law. The 2018 Credit Facility permits the Company to repurchase its common shares as long as no default or event of default exists and other conditions, such as specified consolidated leverage ratios, are met. As of December 31, 2018, the remaining authorized capacity under the Company’s $1.5 billion share repurchase program was $1.5 billion.

In conjunction with the issuance of the 2019 Convertible Notes during February 2014, the Company paid approximately $685.8 million to enter into Forward Transactions with certain financial institutions, or the Forward Counterparties, pursuant to which the Company purchased approximately 19.9 million common shares, at an average cost of $34.51 per share, for settlement on or around the August 15, 2019 maturity date for the 2019 Convertible Notes, subject to the ability of each Forward Counterparty to elect to settle all or a portion of its Forward Transactions early. The Forward Transactions were generally expected to facilitate privately negotiated derivative transactions between the Forward Counterparties and holders of the 2019 Convertible Notes, including swaps, relating to the common shares by which holders of the 2019 Convertible Notes establish short positions relating to the common shares and otherwise hedge their investments in the 2019 Convertible Notes concurrently with, or shortly after, the pricing of the 2019 Convertible Notes. The approximate 19.9 million common shares effectively repurchased through the Forward Transactions are treated as retired shares for basic and diluted EPS purposes. During the year ended December 31, 2018, the Forward Counterparties delivered approximately 13.9 million shares to the Company, which were subsequently retired by the Company, and as a result, the Company expensed $4.3 million of unamortized non-cash issuance costs relating to these shares, which is included in the non-cash interest expense amount disclosed below. As of December 31, 2018, approximately 6.0 million shares still remained legally outstanding.

As a result of the Forward Transactions, the Company’s total shareholders’ deficit within its consolidated balance sheet was increased by approximately $685.8 million during the first quarter of 2014, with amounts of $653.9 million and $31.9 million being allocated between accumulated deficit and additional paid-in capital, respectively, within total shareholders’ deficit. Also, upon executing the Forward Transactions, the Company recorded, at fair value, $35.8 million in non-cash issuance costs to other assets and a corresponding amount to additional paid-in capital within its consolidated balance sheet. These non-cash issuance costs will be amortized to interest expense over the contractual term of the Forward Transactions. For the years ended December 31, 2018, 2017, and 2016, the Company recognized $9.2 million, $6.5 million, and $6.5 million, respectively of non-cash interest expense within its consolidated statements of income relating to amortization of these non-cash issuance costs.

During the year ended December 31, 2018, an indirect wholly-owned subsidiary of the Company purchased 8,400 of Herbalife Nutrition Ltd.’s common shares through open-market purchases at an aggregate cost of approximately $0.3 million, or an average cost of $33.90 per share. During the year ended December 31, 2017, an indirect wholly-owned subsidiary of the Company purchased approximately 10.0 million of Herbalife Nutrition Ltd.’s common shares through open-market purchases at an aggregate cost of approximately $328.6 million, or an average cost of $32.81 per share. These share repurchases increased the Company’s total shareholders’ deficit and are reflected at cost within the Company’s accompanying consolidated balance sheets. Although these shares are owned by an indirect wholly-owned subsidiary of the Company and remain legally outstanding, they are reflected as treasury shares under U.S. GAAP and therefore reduce the number of common shares outstanding within the Company’s consolidated financial statements and the weighted-average number of common shares outstanding used in calculating earnings per share. The common shares of Herbalife Nutrition Ltd. held by the indirect wholly-owned subsidiary, however, remain outstanding on the books and records of the Company’s transfer agent and therefore still carry voting and other share rights related to ownership of the Company’s common shares, which may be exercised. So long as it is consistent with applicable laws, such shares will be voted by such subsidiary in the same manner, and to the maximum extent possible in the same proportion, as all other votes cast with respect to any matter properly submitted to a vote of Herbalife Nutrition Ltd.’s shareholders. As of both December 31, 2018 and 2017, the Company held approximately 10.0 million of treasury shares for U.S. GAAP purposes. In May 2018, the Company completed its modified Dutch auction tender offer and then subsequently paid cash to repurchase and retire a total of approximately 11.4 million of its common shares at an aggregate cost of approximately $600.0 million, or $52.50 per share. In October 2017, the Company completed its modified Dutch auction tender offer and then subsequently paid cash to repurchase and retire a total of approximately 13.5 million of its common shares at an aggregate cost of approximately $457.8 million, or $34.00 per share. In total, the Company repurchased 11.4 million and 23.5 million of its common shares at an aggregate cost of approximately $600.3 million and $786.4 million, or an average cost of $52.49 and $33.49 per share, during the years ended December 31, 2018 and 2017, respectively. The Company did not repurchase any of its common shares in the open market during the year ended December 31, 2016.

In connection with the Company’s October 2017 modified Dutch auction tender offer, the Company incurred $1.6 million in transaction costs and also provided a non-transferable contractual CVR for each share tendered, allowing participants in the tender offer to receive a contingent cash payment in the event Herbalife is acquired in a going-private transaction (as defined in the CVR Agreement) within two years of the commencement of the tender offer. The initial fair value of the CVR was $7.3 million, which was recorded as a liability in the fourth quarter of 2017 with a corresponding decrease to shareholders’ equity. In determining the initial fair value of the CVR, the Company used a lattice model, which included inputs such as the underlying stock price, strike price, time to expiration, and dividend yield. Subsequent changes in the fair value of the CVR liability, using a similar valuation approach as the initial fair value determination, are recognized within the Company's consolidated balance sheet with corresponding gains or losses being recognized in other expense (income), net within the Company's consolidated statements of income during each reporting period until the CVR expires in August 2019 or is terminated due to a going-private transaction, which is also incorporated in the valuation of the CVR; this going-private probability input is considered to be a Level 3 input in the fair value hierarchy and any increase or decrease in this input could have significantly impacted the fair value of the CVR as of the reporting date. Any subsequent increase or decrease in this input or other inputs described above in subsequent valuations could significantly impact the fair value of the CVR. The Company recognized an $8.8 million loss in other expense (income), net within its consolidated statement of income during the year ended December 31, 2018 due to the change in the fair value of the CVR, which was primarily driven by an increase in the market price of the Company’s common shares, partially offset by a decrease in the probability of a going-private transaction as a result of the shortening term of the CVR before it expires pursuant to its terms. The Company recognized a $0.4 million gain in other expense (income), net within its consolidated statement of income during the year ended December 31, 2017 due to the change in the fair value of the CVR. As of December 31, 2018 and 2017, the fair value of the CVR was $15.7 million and $6.9 million, respectively.

The number of shares issued upon vesting or exercise for certain restricted stock units and SARs granted pursuant to the Company’s share-based compensation plans is net of the statutory withholding requirements that the Company pays on behalf of its employees. Although shares withheld are not issued, they are treated as common share repurchases in the Company’s consolidated financial statements, as they reduce the number of shares that would have been issued upon vesting. These shares do not count against the authorized capacity under the Company’s share repurchase program described above. During the years ended December 31, 2018, 2017, and 2016, the Company withheld shares on its vested restricted stock units and exercised SARs relating to its share-based compensation plans.

The Company reflects the aggregate purchase price of its common shares repurchased as an increase to shareholders’ deficit. The Company generally allocated the purchase price of the repurchased shares to accumulated deficit, common shares, and additional paid-in capital, with the exception of treasury shares, which are recorded separately on the Company’s consolidated balance sheets.

For the years ended December 31, 2018, 2017, and 2016, the Company’s share repurchases, inclusive of transaction costs and the issuance of the CVR, were $600.7 million, $795.3 million, and none, respectively, under the Company’s share repurchase programs, and $145.4 million, $60.4 million, and $13.2 million, respectively, due to shares withheld for tax purposes related to the Company’s share-based compensation plans. For the years ended December 31, 2018, 2017, and 2016, the Company’s total share repurchases, including shares withheld for tax purposes, were $746.1 million, $855.7 million, and $13.2 million, respectively, and have been recorded as an increase to shareholders’ deficit within the Company’s consolidated balance sheets. The Company recorded $750.3 million of total share repurchases within financing activities on its consolidated statement of cash flows for the year ended December 31, 2018, which includes $4.2 million of share repurchases that were reflected as an increase to shareholders’ deficit within the Company’s consolidated balance sheet as of December 31, 2017 but were subsequently paid during the year ended December 31, 2018. The Company recorded $844.2 million of total share repurchases within financing activities on its consolidated statement of cash flows for the year ended December 31, 2017, which excludes $4.2 million of share repurchases for which payment was made subsequent to the year end and therefore reflected as a liability within the Company’s consolidated balance sheet as of December 31, 2017, and the $7.3 million initial fair value of the CVR.

Capped Call Transactions

In February 2014, in connection with the issuance of the 2019 Convertible Notes, the Company paid approximately $123.8 million to enter into Capped Call Transactions with certain financial institutions. The Capped Call Transactions are expected generally to reduce the potential dilution upon conversion of the 2019 Convertible Notes in the event that the market price of the common shares is greater than the strike price of the Capped Call Transactions, initially set at $43.14 per common share based on the retroactive adjustment due to the Company’s two-for-one stock split described in Note 2, Basis of Presentation, with such reduction of potential dilution subject to a cap based on the cap price initially set at $60.39 per common share based on the retroactive adjustment due to the Company’s two-for-one stock split described in Note 2, Basis of Presentation. The strike price and cap price are subject to certain adjustments under the terms of the Capped Call Transactions. Therefore, as a result of executing the Capped Call Transactions, the Company in effect will only be exposed to potential net dilution once the market price of its common shares exceeds the adjusted cap price. As of December 31, 2018, the weighted-average adjusted cap price was approximately $54.30 per common share. As a result of the Capped Call Transactions, the Company’s additional paid-in capital within shareholders’ deficit on its consolidated balance sheet was reduced by $123.8 million during the first quarter of 2014.

During March 2018, in connection with the Company’s repurchase of a portion of the 2019 Convertible Notes, the Company entered into partial settlement agreements with the option counterparties to the Capped Call Transactions to terminate a portion of such existing transactions, in each case, in a notional amount corresponding to the aggregate principal amount of 2019 Convertible Notes that were repurchased. As a result of terminating a portion of the Capped Call Transactions, which were in a favorable position, the Company received $55.9 million in cash and recognized an offsetting increase to additional paid-in capital as of December 31, 2018.

Share-Based Compensation

9. Share-Based Compensation

The Company has four share-based compensation plans: the Amended and Restated Herbalife Ltd. 2005 Stock Incentive Plan, or the 2005 Stock Incentive Plan, the Amended and Restated Herbalife Ltd. 2014 Stock Incentive Plan, or the 2014 Stock Incentive Plan, the Amended and Restated Herbalife Ltd. Independent Directors Deferred Compensation and Stock Unit Plan, or the Independent Director Stock Unit Plan, and the Amended and Restated Non-Management Directors Compensation Plan, or the Non-Management Directors Plan. The 2014 Stock Incentive Plan replaced the 2005 Stock Incentive Plan and after the adoption thereof, no additional awards were made under the 2005 Stock Incentive Plan. The terms of the 2014 Stock Incentive Plan are substantially similar to the terms of the 2005 Stock Incentive Plan. The 2014 Stock Incentive Plan authorizes the issuance of 17,400,000 common shares pursuant to awards granted under the plan, plus any shares that remained available for issuance under the 2005 Stock Incentive Plan as of April 29, 2014. The purpose of the Independent Directors Stock Unit Plan and the Non-Management Directors Plan is to facilitate equity ownership in the Company by its directors through equity awards. As of December 31, 2018, an aggregate of approximately 6.3 million common shares remain available for future issuance under the 2014 Stock Incentive Plan.

The Company’s share-based compensation plans generally provide for grants of stock options, SARs, and stock unit awards, which are collectively referred to herein as awards. Certain SARs generally vest annually over a three-year period. The contractual term of stock options and SARs is generally ten years. Certain stock unit awards under the 2014 Stock Incentive Plan vest annually over a three year period. Certain stock unit awards subject to service and performance conditions vest after the passage of a performance period as determined by the compensation committee of the Company’s board of directors. Stock unit awards granted to directors generally vest over a one-year period.

Awards can be subject to the following: market and service conditions, or market condition awards; performance and service conditions, or performance condition awards; market, service and performance conditions, or market and performance condition awards; or be subject only to continued service with the Company, or service condition awards. All awards granted by the Company are market condition awards, performance condition awards, or service condition awards. Unless otherwise determined at the time of grant, upon vesting, each stock unit award represents the right to receive one common share. For stock unit awards, the Company issues new shares, net of shares withheld for tax purposes, when vested. For SARs, the Company issues new shares based on the intrinsic value when exercised, net of shares withheld for tax purposes. The Company’s stock compensation awards outstanding as of December 31, 2018 include SARs and stock unit awards.

There were no SARs with performance conditions granted during the year ended December 31, 2018. During the years ended December 31, 2017 and 2016, the Company granted SARs with performance conditions to certain employees. These awards generally vest 20% in the first succeeding year, 20% in the second succeeding year, and 60% in the third succeeding year, subject to achievement of certain sales leader retention metrics. The fair value of these SARs was determined on the date of grant using the Black-Scholes-Merton option pricing model. The compensation expense for these grants is recognized over the vesting term using the graded vesting method.

There were no SARs with service conditions granted during the year ended December 31, 2018. During the years ended December 31, 2017 and 2016, the Company granted SARs with service conditions to certain employees. The fair value of these SARs was determined on the date of grant using the Black-Scholes-Merton option pricing model. The compensation expense for these grants is recognized over the vesting term using the straight line method.

During the years ended December 31, 2018 and 2017, the Company granted performance stock unit awards to certain executives, which will vest on December 31, 2020 and December 31, 2019, respectively, subject to their continued employment through that date and the achievement of certain performance conditions. The performance conditions include targets for local currency net sales, Volume Points, adjusted earnings before interest and taxes, and adjusted earnings per share. These performance stock unit awards can vest at between 0% and 200% of the target award based on the achievement of the performance conditions.

During the years ended December 31, 2018 and 2017, the Company granted stock unit awards with service conditions to directors and certain employees.

Share-based compensation expense is included in selling, general, and administrative expenses within the Company’s consolidated statements of income. The Company’s policy is to estimate the number of forfeitures expected to occur. For the years ended December 31, 2018, 2017, and 2016, share-based compensation expense relating to service condition awards amounted to $26.2 million, $24.4 million, and $23.9 million, respectively. For the years ended December 31, 2018, 2017, and 2016, share-based compensation expense relating to market condition awards amounted to less than $0.1 million, $1.3 million, and $0.4 million, respectively. For the years ended December 31, 2018, 2017, and 2016, share-based compensation expense relating to performance condition awards amounted to $9.2 million, $16.4 million, and $15.9 million, respectively. For the years ended December 31, 2018, 2017, and 2016, the related income tax benefits recognized in earnings for all awards amounted to $8.1 million, $9.4 million, and $14.8 million, respectively. Excess tax benefits on share-based compensation arrangements totaled $53.1 million, $31.1 million, and $0.4 million for the years ended December 31, 2018, 2017, and 2016, respectively.

As of December 31, 2018, the total unrecognized compensation cost related to non-vested service condition stock awards was $38.0 million and the related weighted-average period over which it is expected to be recognized is approximately 1.3 years. As of December 31, 2018, the total unrecognized compensation cost related to non-vested performance condition awards was $11.2 million and the related weighted-average period over which it is expected to be recognized is approximately 1.6 years.

Stock unit awards are valued at the market value on the date of grant. The fair value of service condition SARs and performance condition SARs are estimated on the date of grant using the Black-Scholes-Merton option-pricing model. The fair value of SARs with market conditions or with market and performance conditions are estimated on the date of grant using the Monte Carlo lattice model. The Company calculates the expected term of its SARs based on historical data. All groups of employees have been determined to have similar historical exercise patterns for valuation purposes. The expected volatility of the SARs is based upon the historical volatility of the Company’s common shares and is also validated against the volatility rates of a peer group of companies. The risk free interest rate is based on the implied yield on a U.S. Treasury zero-coupon issue with a remaining term equal to the expected term of the SARs. The expected dividend yield assumption is based on the Company’s historical and expected amount of dividend payouts.

There were no SARs granted during the year ended December 31, 2018. There were no SARs granted to independent directors during the years ended December 31, 2017, and 2016.

The following table summarizes the weighted-average assumptions used in the calculation of the fair value for service condition SARs awards for the years ended December 31, 2017, and 2016:

		Year Ended December 31,
		2017
