4. Long-Term Debt

Long-term debt consists of the following:

Senior Secured Credit Facility

On March 9, 2011, the Company entered into a $700.0 million senior secured revolving credit facility, or the Credit Facility, with a syndicate of financial institutions as lenders and terminated its prior senior secured credit facility, or the Prior Credit Facility. The Credit Facility has a five year maturity and expires on March 9, 2016. Based on the Company’s consolidated leverage ratio, U.S. dollar borrowings under the Credit Facility bear interest at either LIBOR plus the applicable margin between 1.50% and 2.50% or the base rate plus the applicable margin between 0.50% and 1.50%. The base rate under the Credit Facility represents the highest of the Federal Funds Rate plus 0.50%, one-month LIBOR plus 1.00%, and the prime rate offered by Bank of America. The Company, based on its consolidated leverage ratio, pays a commitment fee between 0.25% and 0.50% per annum on the unused portion of the Credit Facility. The Credit Facility also permits the Company to borrow limited amounts in Mexican Peso and Euro currencies based on variable rates.

In March 2011, the Company used $196.0 million in U.S. dollar borrowings under the Credit Facility to repay all amounts outstanding under the Prior Credit Facility. The Company incurred approximately $5.7 million of debt issuance costs in connection with the Credit Facility. These debt issuance costs were recorded as deferred financing costs on the Company’s consolidated balance sheet and are being amortized over the term of the Credit Facility.

On July 26, 2012, the Company amended the Credit Facility to include a $500.0 million term loan with a syndicate of financial institutions as lenders, or the Term Loan. The Term Loan is a part of the Credit Facility and is in addition to the Company’s current revolving credit facility. The Term Loan matures on March 9, 2016. The Company will make regular scheduled payments for the Term Loan consisting of both principal and interest components. Based on the Company’s consolidated leverage ratio, the Term Loan bears interest at either LIBOR plus the applicable margin between 1.50% and 2.50% or the base rate plus the applicable margin between 0.50% and 1.50% which are the same terms as the Company’s revolving credit facility.

In July 2012, the Company used all $500.0 million of the borrowings under the Term Loan to pay down amounts outstanding under the Company’s revolving credit facility. The Company incurred approximately $4.5 million of debt issuance costs in connection with the Term Loan. The debt issuance costs are recorded as deferred financing costs on the Company’s consolidated balance sheet and will be amortized over the life of the Term Loan.

In February 2014, in connection with issuing the $1.15 billion Convertible Notes described below, the Company amended the Credit Facility. Pursuant to this amendment, the Company amended the terms of the Credit Facility to provide for technical amendments to the indebtedness, asset sale and dividend covenants and the cross-default event of default to accommodate the issuance of the Convertible Notes and the capped call and prepaid forward share repurchase transactions described in greater detail in Note 10, Shareholders’ Equity. The amendment also increased by 0.50% the highest applicable margin payable by Herbalife in the event that Herbalife’s consolidated total leverage ratio is equal to or exceeds 2.50 to 1.00 and increased the permitted consolidated total leverage ratio of Herbalife under the Credit Facility. The Company incurred approximately $2.3 million of debt issuance costs in connection with the amendment. The debt issuance costs are recorded as deferred financing costs on the Company’s consolidated balance sheet and will be amortized over the life of the Credit Facility. On March 31, 2014 and December 31, 2013, the weighted average interest rate for borrowings under the Credit Facility, including borrowings under the Term Loan, was 3.16% and 2.17%, respectively.

The Credit Facility requires the Company to comply with a leverage ratio and a coverage ratio. In addition, the Credit Facility contains customary 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. As of March 31, 2014, and December 31, 2013, the Company was compliant with its debt covenants under the Credit Facility.

During the three months ended March 31, 2014, the Company repaid a total amount of $18.8 million under the Credit Facility. As of March 31, 2014, and December 31, 2013, the U.S. dollar amount outstanding under the Credit Facility was $912.5 million and $931.3 million, respectively. Of the $912.5 million U.S. dollar amount outstanding under the Credit Facility as of March 31, 2014, $412.5 million was outstanding on the Term Loan and $500.0 million was outstanding on the revolving credit facility. Of the $931.3 million U.S. dollar amount outstanding under the Credit Facility as of December 31, 2013, $431.3 million was outstanding on the Term Loan and $500.0 million was outstanding on the revolving credit facility. There were no outstanding foreign currency borrowings as of March 31, 2014 and December 31, 2013 under the Credit Facility.

The fair value of the outstanding borrowings on the Company’s revolving credit facility and Term Loan approximated their carrying values as of March 31, 2014, due to their variable interest rates which reprice frequently and represent floating market rates. The fair value of the outstanding borrowings on the Company’s revolving credit facility and Term Loan are determined by utilizing Level 2 inputs as defined in Note 12, Fair Value Measurements, such as observable market interest rates and yield curves.

Convertible Senior Notes

During February 2014, the Company initially issued $1 billion aggregate principal amount of convertible senior notes, or 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 Convertible Notes which was subsequently exercised in full during February 2014, resulting in a total issuance of $1.15 billion aggregate principal amount of Convertible Notes. The 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 Convertible Notes mature on August 15, 2019, unless earlier repurchased or converted. The Company may not redeem the Convertible Notes prior to their stated maturity date. Holders of the 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 Convertible Notes on each applicable trading day; (ii) during the five business-day period immediately after any five consecutive trading day period, which we refer to as the measurement period, in which the trading price per $1,000 principal amount of Convertible Notes for each trading day of that measurement period was less than 98% of the product of the last reported sale price of our common shares and the conversion rate for the 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 Convertible Notes at any time, regardless of the foregoing circumstances. Upon conversion, the 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 Convertible Notes had an initial conversion rate of 11.5908 common shares per $1,000 principal amount of the Convertible Notes (which is equal to an initial conversion price of approximately $86.28 per common share).

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

During February 2014, the $1.15 billion proceeds received from the issuance of the 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 Convertible Notes as a whole. Since the Company must still settle these 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 Convertible Notes remain outstanding. The effective interest rate on the 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.

As of March 31, 2014, the outstanding principal on the Convertible Notes was $1.15 billion, the unamortized debt discount was $214.2 million, and the carrying amount of the liability component was $935.8 million, which was recorded to long-term debt within the Company’s condensed consolidated balance sheet as reflected in the table above within this Note. As of March 31, 2014, the fair value of the liability component relating to the Convertible Notes was approximately $871 million. At March 31, 2014, the Company determined the fair value of the liability component of the Convertible Notes by reviewing 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 interest rates, credit standing, and yield curves, all of which are defined as level 2 observable inputs. The Company also used a lattice model, which primarily included level 2 inputs such as stock price, volatility, debt yield and dividend yield rates, and level 3 inputs, such as the price of the Convertible Notes at March 31, 2014. Since the Convertible Notes are not publicly traded, the price of the Convertible Notes at March 31, 2014, was obtained from third party sources; these third party sources used level 3 inputs, including private transactions, bid and offer prices, and other market adjustments in order to determine the price of the Convertible Notes at March 31, 2014. This valuation approach was similar to the approach the Company used to determine the initial fair value of the liability component of the Convertible Notes on the February 7, 2014, issuance date except that the price of the Convertible Notes on the February 7, 2014, issuance date would not be considered a level 3 input as the Convertible Notes price paid by the market participants on the issuance date was an observable input.

In conjunction with the issuance of the 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. See Note 10, Shareholders’ Equity, for additional discussion on the Forward Transactions and Capped Call Transactions entered into in conjunction with the issuance of these Convertible Notes.

During the three months ended March 31, 2014, the Company recognized $8.8 million of interest expense relating to the Convertible Notes, which included $4.9 million relating to non-cash interest expense relating to the debt discount and $0.5 million relating to amortization of deferred financing costs. The Company’s total interest expense, including the Credit Facility, was $17.8 million and $6.8 million for the three months ended March 31, 2014 and 2013, respectively, which was recognized within its condensed consolidated statement of income.

As of March 31, 2014, the aggregate annual maturities of the Credit Facility were expected to be $62.5 million for the remainder of 2014, $100.0 million for 2015, and $750.0 million for 2016. The $1.15 billion Convertible Notes are due 2019.
