4. Long-Term Debt

Long-term debt consists of the following:

Senior Secured Credit Facility

On May 4, 2015, the Company amended its prior senior secured credit facility, or the Prior Credit Facility, to extend the maturity date of its revolving credit facility, or the Prior Revolving Credit Facility, by one year to March 9, 2017. Pursuant to this amendment and upon execution, the Company made prepayments of approximately $20.3 million and $50.9 million on its $500.0 million term loan under the Prior Credit Facility, or the Prior Term Loan, and the Prior Revolving Credit Facility, respectively. Additionally, the Company’s $700.0 million borrowing capacity on its Prior Revolving Credit Facility was reduced by approximately $235.9 million upon execution of this amendment, and was further reduced by approximately $39.1 million on September 30, 2015, bringing the total available borrowing capacity to $425.0 million. The Prior Term Loan matured on March 9, 2016 and was repaid in full. Prior to March 9, 2016, the interest rates on the Company’s borrowings under the Prior Credit Facility remained effectively unchanged except that the minimum applicable margin was increased by 0.50% and LIBOR was subject to a minimum floor of 0.25%. After March 9, 2016, the applicable interest rates on the Company’s borrowings under the Prior Credit Facility increased by 2.00% such that borrowings under the Prior Credit Facility began bearing 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. The Company incurred approximately $6.2 million of debt issuance costs in connection with the amendment. These debt issuance costs were recorded on the Company’s condensed consolidated balance sheet and were amortized over the life of the Prior Revolving Credit Facility.

On February 15, 2017, the Company entered into a new $1,450.0 million senior secured credit facility, or the Credit Facility, consisting of a $1,300.0 million term loan B, or the Term Loan, and a $150.0 million revolving credit facility, or the Revolving Credit Facility, with a syndicate of financial institutions as lenders, or Lenders. The Revolving Credit Facility matures on February 15, 2022 and the Term Loan matures on February 15, 2023. However, if the outstanding principal on the 2019 Convertible Notes, as defined below, exceeds $250.0 million and the Company exceeds certain leverage ratios on February 14, 2019, the Revolving Credit Facility will mature on such date. In addition, if the outstanding principal on the 2019 Convertible Notes, as defined below, exceeds $250.0 million and the Company exceeds certain leverage ratios on May 16, 2019, the Term Loan will mature on such date. The Credit Facility is secured by the equity interests of certain of Herbalife Nutrition Ltd.’s subsidiaries and substantially all of the assets of the domestic loan parties. The 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 Term Loan was issued to the Lenders at a 2% discount, or $26.0 million. In connection with the Credit Facility, the Company also repaid the $410.0 million outstanding balance on its Prior Revolving Credit Facility. The Company incurred approximately $22.6 million of debt issuance costs in connection with the Credit Facility. The debt issuance costs and the discount are recorded on the Company’s condensed consolidated balance sheet and are being amortized over the life of the Credit Facility using the effective-interest method.

Borrowings under the Term Loan bear interest at either the eurocurrency rate plus a margin of 5.50% or the base rate plus a margin of 4.50%. Prior to August 15, 2017, borrowings under the Revolving Credit Facility bore interest at the eurocurrency rate plus a margin of 4.75% or the base rate plus a margin of 3.75%. After August 15, 2017, borrowings under the Revolving Credit Facility, depending on the Company’s consolidated leverage ratio, bear 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%. 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 set by Credit Suisse, and is subject to a floor of 1.75%. The eurocurrency rate is based on adjusted LIBOR and is subject to a floor of 0.75%. The Company is required to pay a commitment fee on the Revolving Facility of 0.50% per annum on the undrawn portion of the Revolving Credit Facility. Interest is due at least quarterly on amounts outstanding on the Credit Facility.

The Credit Facility requires the Company to comply with a leverage ratio. In addition, the Credit Facility contains customary events of default and covenants, including covenants that limit or restrict the Company’s ability to incur liens, incur indebtedness, make investments, dispose of assets, make certain restricted payments, pay dividends, repurchase its common shares, merge or consolidate and enter into certain transactions with affiliates. The Company is also required to maintain a minimum balance of $200.0 million of consolidated cash and cash equivalents. As of June 30, 2018 and December 31, 2017, the Company was in compliance with its debt covenants under the Credit Facility.

The Term Loan is payable in consecutive quarterly installments each in an aggregate principal amount of $24.4 million which began on June 30, 2017. In addition, the Company may be required to make mandatory prepayments towards the Term Loan based on the Company’s consolidated leverage ratio and annual excess cash flows as defined under the terms of the Credit Facility. The Company is also permitted to make voluntary prepayments. These prepayments, if any, will be applied against remaining quarterly installments owed under the Term Loan in order of maturity with the remaining principal due upon maturity.

As of June 30, 2018 and December 31, 2017, the weighted-average interest rate for borrowings under the Credit Facility was 7.34% and 6.79%, respectively.

During the three months ended March 31, 2018, the Company repaid a total amount of $24.4 million on amounts outstanding under the Credit Facility. During the three months ended June 30, 2018, the Company repaid a total amount of $24.4 million on amounts outstanding under the Credit Facility. During the three months ended March 31, 2017, the Company repaid a total amount of $410.0 million to repay in full amounts outstanding under the Prior Revolving Credit Facility. During the three months ended June 30, 2017, the Company repaid a total amount of $24.4 million on amounts outstanding under the Credit Facility. As of June 30, 2018 and December 31, 2017, the U.S. dollar amount outstanding under the Term Loan was $1,178.1 million and $1,226.9 million, respectively. There were no borrowings outstanding under the Revolving Credit Facility as of June 30, 2018 and December 31, 2017. There were no outstanding foreign currency borrowings as of June 30, 2018 and December 31, 2017 under the Credit Facility.

During the three months ended June 30, 2018 and 2017, the Company recognized $24.5 million and $23.4 million, respectively, of interest expense relating to the Term Loan, which included $1.2 million and $1.2 million, respectively, relating to non-cash interest expense relating to the debt discount and $0.7 million and $0.8 million, respectively, relating to amortization of debt issuance costs. During the six months ended June 30, 2018 and 2017, the Company recognized $48.2 million and $34.6 million, respectively, of interest expense relating to the Term Loan, which included $2.3 million and $1.8 million, respectively, relating to non-cash interest expense relating to the debt discount and $1.5 million and $1.2 million, respectively, relating to amortization of debt issuance costs.

The fair value of the outstanding borrowings on the Term Loan is determined by utilizing over-the-counter market quotes, which are considered Level 2 inputs as described in Note 12, Fair Value Measurements. As of June 30, 2018 and December 31, 2017, the carrying amount of the Term Loan was $1,145.3 million and $1,190.2 million, respectively, and the fair value was approximately $1,189.2 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 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, Significant Accounting Policies. 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 June 30, 2018.

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 condensed consolidated balance sheet is 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 condensed 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 condensed 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, net within the Company’s condensed consolidated statement of income. The accounting impact of the new 2024 Convertible Notes is described in further detail below.

As of June 30, 2018, the remaining outstanding principal on the 2019 Convertible Notes was $675.0 million, the unamortized debt discount and debt issuance costs were $33.0 million, and the carrying amount of the liability component was $642.0 million, which was recorded to current portion of long-term debt within the Company’s condensed consolidated balance sheet, as holders may convert their 2019 Convertible Notes at any time on and after May 15, 2019 as described above within this Note. 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 condensed consolidated balance sheet. The fair value of the liability component relating to the 2019 Convertible Notes was approximately $637.7 million and $1,066.0 million as of June 30, 2018 and December 31, 2017, respectively.

During the three months ended June 30, 2018 and 2017, the Company recognized $10.4 million and $17.0 million, respectively, of interest expense relating to the 2019 Convertible Notes, which included $6.4 million and $10.2 million, respectively, relating to non-cash interest expense relating to the debt discount and $0.6 million and $1.0 million, respectively, relating to amortization of debt issuance costs. During the six months ended June 30, 2018 and 2017, the Company recognized $27.4 million and $33.7 million, respectively, of interest expense relating to the 2019 Convertible Notes, which included $16.8 million and $20.2 million, respectively, relating to non-cash interest expense relating to the debt discount and $1.6 million and $2.0 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 10, 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 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, Significant Accounting Policies. 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 June 30, 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, is 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 June 30, 2018, the outstanding principal on the 2024 Convertible Notes was $550.0 million, the unamortized debt discount and debt issuance costs were $144.2 million, and the carrying amount of the liability component was $405.8 million, which was recorded to long-term debt within the Company’s condensed consolidated balance sheet. The fair value of the liability component relating to the 2024 Convertible Notes was approximately $423.2 million as of June 30, 2018.

During the three months ended June 30, 2018, the Company recognized $8.5 million of interest expense relating to the 2024 Convertible Notes, which included $4.5 million relating to non-cash interest expense relating to the debt discount and $0.3 million relating to amortization of debt issuance costs. During the six months ended June 30, 2018, the Company recognized $9.3 million of interest expense relating to the 2024 Convertible Notes, which included $5.0 million relating to non-cash interest expense relating to the debt discount and $0.3 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.

Total Debt

The Company’s total interest expense was $49.1 million and $41.9 million for the three months ended June 30, 2018 and 2017, respectively, and $93.7 million and $74.4 million for the six months ended June 30, 2018 and 2017, respectively, which was recognized within its condensed consolidated statements of income.

As of June 30, 2018, annual scheduled principal payments of debt were as follows:

Certain vendors and government agencies may require letters of credit or similar guaranteeing arrangements to be issued or executed. As of June 30, 2018, the Company had $37.5 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 5, Contingencies.
