Accounting Policies [Abstract]
Basis of Presentation	2. Basis of Presentation The Company’s consolidated financial statements refer to Herbalife Ltd. and its subsidiaries. New Accounting 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) In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date , which deferred the effective date of ASU No. 2014-09 for all entities by one year to annual reporting periods beginning after December 15, 2017. In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers (Topic 606), Principal versus Agent Considerations (Reporting Revenue versus Net) , which clarifies the implementation guidance on principal versus agent considerations in the new revenue recognition standard. ASU 2016-08 clarifies how an entity should identify the unit of accounting (i.e. the specified good or service) for the principal versus agent evaluation and how it should apply the control principle to certain types of arrangements. In April 2016, the FASB issued ASU 2016-10, Revenue from Contracts with Customers (Topic 606), Identifying Performance Obligations and Licensing , which clarifies the implementation guidance on how an entity should identify performance obligations in contracts with customers, and how it should account for licensing arrangements with customers. In May 2016, the FASB issued ASU 2016-12, Narrow-Scope Improvements and Practical Expedients , 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 In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements — Going Concern (Subtopic 205-40) In July 2015, the FASB issued ASU No. 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements. In November 2015, the FASB issued ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes 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 In February 2016, the FASB issued ASU No. 2016-02, Leases (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. A modified retrospective approach must be applied for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The Company is evaluating the potential impact of this adoption on its consolidated financial statements, however, increases in both assets and liabilities are expected. 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 In March 2016, the FASB issued ASU No. 2016-05, Derivatives and Hedging (Topic 815): Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships The adoption of this guidance will not have a material impact on the Company’s consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-06, Derivatives and Hedging (Topic 815): Contingent Put and Call Options in Debt Instruments Derivatives and Hedging The adoption of this guidance will not have a material impact on the Company’s consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, Compensation — Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting Income Taxes 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, 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 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 amendments in this update are effective for reporting periods beginning after December 15, 2017, with early adoption permitted. The Company is evaluating the potential impact of this adoption on its 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 Consolidation In October 2016, the FASB issued ASU No. 2016-17, Consolidation (Topic 810): Interests Held Through Related Parties That Are Under Common Control This ASU changes how a single decision maker will consider its indirect interests when performing the primary beneficiary analysis under the variable interest entity, or VIE, model. The amendments in this update require that a single decision maker consider the indirect interest held by a related party under common control on a proportionate basis, not in its entirety as previously required. The amendments in this update do not change the characteristics of a primary beneficiary in the VIE model. The amendments of this ASU are effective for reporting periods beginning after December 15, 2016, with early adoption permitted. 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 amendments of this ASU are effective for reporting periods beginning after December 15, 2017, with early adoption permitted. In January 2017, the FASB issued ASU No. 2017-04, Intangibles — Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment Significant Accounting Policies Consolidation Policy The consolidated financial statements include the accounts of Herbalife 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 Forward Exchange Contracts and Interest Rate Swaps 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 also previously entered into interest rate swaps in managing its interest rate risk on its variable rate credit facility. The Company does not use the contracts for trading purposes. In accordance with FASB Accounting Standards Codification, or ASC, Topic 815, Derivatives and Hedging 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, 2016 and December 31, 2015, 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 $51.8 million and $49.3 million as of December 31, 2016 and 2015, respectively. Substantially all of the receivables from credit card companies were current as of December 31, 2016 and 2015. Although receivables from importers can be significant, 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, 2016, 2015, and 2014, the Company recorded $1.0 million, $3.7 million, and $2.2 million, respectively, in bad-debt expense related to allowances for the Company’s receivables. As of December 31, 2016 and 2015, the Company’s allowance for doubtful accounts was $1.3 million and $1.5 million, respectively. As of December 31, 2016 and 2015, 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 available-for-sale investments are based on prices of similar assets traded in active markets and observable yield curves; • The fair value of option and forward contracts are based on dealer quotes; and • The Company’s variable rate revolving credit facility is recorded at carrying value and is considered to approximate its fair value. The Company’s convertible senior notes issued in February 2014, or the Convertible Notes, are recorded at carrying value, and their fair value is determined 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 Notes trading price, volatility and dividend yield as of December 31, 2016, 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 Convertible Notes. See Note 4, Long-Term Debt Inventories Inventories are stated at the 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 $7.9 million, $8.5 million, and $6.8 million for the years ended December 31, 2016, 2015 and 2014, respectively. As of December 31, 2016 and 2015, the Company’s remaining unamortized debt issuance cost was $11.9 million and $19.8 million, respectively. Long-Lived Assets At December 31, 2016 and 2015, the Company’s net property, plant and equipment consisted of the following (in millions): December 31, 2016 2015 Property, plant and equipment — at cost: Land and Building $ 51.0 $ 22.2 Furniture and fixtures 25.9 25.0 Equipment 719.8 652.4 Building and leasehold improvements 185.7 177.0 982.4 876.6 Less: accumulated depreciation and amortization (604.4 ) (537.4 ) Net property, plant and equipment $ 378.0 $ 339.2 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, 2016 and 2015, these amounts have been reflected in property, plant and equipment on the Company’s accompanying consolidated balance sheets. Depreciation of furniture, fixtures, and equipment (includes 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, was $145.7 million and $140.2 million as of December 31, 2016 and 2015, 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 $80.7 million, $82.5 million, and $81.5 million, for the years ended December 31, 2016, 2015, and 2014, 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 uses 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 uses 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, 2016, 2015, and 2014, there were no additions to goodwill or marketing related intangible assets or impairments of goodwill or marketing related intangible assets. At December 31, 2016 and 2015, 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, 2016 and 2015, the goodwill balance was $89.9 million and $91.8 million, respectively. The decreases in goodwill during the years ended December 31, 2016 and 2015 were due to cumulative translation adjustments. Other Assets Other assets on the Company’s accompanying consolidated balance sheets include long-term deferred tax assets of $155.2 million and $7.8 million at December 31, 2016 and 2015, respectively. As noted above in Note 2, Basis of Presentation , the 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. See Note 12, Income Taxes, 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. 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. Components of accumulated other comprehensive income (loss) consisted of the following (in millions): December 31, 2016 2015 2014 Foreign currency translation adjustment, net of tax $ (215.5 ) $ (183.0 ) $ (96.4 ) Unrealized gain on derivatives, net of tax 10.4 17.4 18.0 Unrealized gain on available-for-sale investments, net of tax — 0.1 0.2 Total accumulated other comprehensive loss $ (205.1 ) $ (165.5 ) $ (78.2 ) 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. During the year ended December 31, 2016, the Company recognized government grant income of approximately $34.2 million in other operating income within its consolidated statements of income, related to its regional headquarters and distribution centers within China. To conform with the current period presentation, for the year ended December 31, 2015, $6.5 million in government grant income in China has been reclassified from selling, general, and administrative expenses to other operating income within its consolidated statements of income. The Company did not recognize any such grant income in the year ended December 31, 2014. 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 financial statements 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 in the Company’s consolidated statements of income. Advertising Advertising costs, including Company sponsorships, are expensed as incurred and amounted to approximately $64.8 million, $66.1 million, and $69.7 million for the years ended December 31, 2016, 2015, and 2014, respectively. These expenses are included in selling, general and administrative expenses in the accompanying consolidated statements of income. Earnings Per Share Basic earnings per share represents net income for the period common shares were outstanding, 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 options, SARs and stock units. The following are the common share amounts used to compute the basic and diluted earnings per share for each period (in millions): Year Ended December 31, 2016 2015 2014 Weighted average shares used in basic computations 83.0 82.6 86.3 Dilutive effect of exercise of equity grants outstanding 3.1 2.7 4.5 Weighted average shares used in diluted computations 86.1 85.3 90.8 There were an aggregate of 4.5 million, 5.4 million, and 2.7 million of equity grants, consisting of stock options, SARs, and stock units that were outstanding during the years ended December 31, 2016, 2015, and 2014, 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 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 initial conversion price of $86.28 per share. For the years ended December 31, 2016, 2015, and 2014, the 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 Convertible Notes exceeded the average market price of the Company’s common shares for the years ended December 31, 2016, 2015, and 2014. The initial conversion rate and conversion price is described further in Note 4, Long-Term Debt The Capped Call Transactions executed in connection with the issuance of the Convertible Notes are excluded from the calculation of diluted earnings per share because their impact is always anti-dilutive. Revenue Recognition The Company generally recognizes revenue upon delivery and when both the title and risk and rewards pass to the Member or importer, or as products are sold Non-Cash Investing and Financing Activities During the years ended December 31, 2016, 2015 and 2014, the Company recorded $12.7 million, $12.3 million, and $12.3 million, respectively, of non-cash capital expenditures. In addition, during the year ended December 31, 2015, the Company recorded $15.0 million of a non-cash release of deposits in escrow that were used to reduce the Company’s accrued expense liability. During the years ended December 31, 2016 and 2015, the Company recorded $20.8 million and $17.3 million of non-cash borrowings that were used to finance software maintenance. Additionally, see Note 8, Shareholders’ (Deficit) Equity 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. Venezuela The adverse operating environment in Venezuela continues to be challenging for the Company’s Venezuela business, with high inflation, pricing limitations, importation restrictions, and foreign exchange restrictions. Foreign exchange controls in Venezuela continue to limit Herbalife Venezuela’s ability to repatriate earnings and settle its intercompany shipment obligations at any official rate. As a result, this has continued to significantly limit Herbalife Venezuela’s ability to acquire its U.S. dollar denominated raw materials and finished good inventory. Despite these currency exchange restrictions, the Company continues to control Herbalife Venezuela and its operations. Venezuela’s inflation rate as measured using the blended National Consumer Price Index and Consumer Price Index rate exceeded a three-year cumulative inflation rate of 100% as of December 31, 2009. Accordingly, effective January 1, 2010, Venezuela was considered a highly inflationary economy. Pursuant to the highly inflationary basis of accounting under U.S. GAAP, Herbalife Venezuela changed its functional currency from the Bolivar to the U.S. dollar and the Company no longer translates Herbalife Venezuela’s financial statements as its functional currency is the U.S. dollar. During the years ended December 31, 2016, 2015, and 2014, the Company recognized foreign exchange losses and other related charges of $7.2 million, $42.8 million and $229.0 million within its consolidated statements of income related to its Venezuelan operations, respectively. Herbalife Venezuela’s net sales represented less than 1% for the years ended December 31, 2016 and 2015 and approximately 3% of the Company’s consolidated net sales for the year ended December 31, 2014, and its total assets represented less than 1% of the Company’s consolidated total assets as of December 31, 2016 and 2015. As of December 31, 2016 and 2015, Herbalife Venezuela’s cash and cash equivalents primarily consisted of Bolivar-denominated cash of approximately $0.8 million and $7.7 million, respectively.

Long-Term Debt	4. Long-Term Debt Long-term debt consists of the following (in millions): December 31, 2016 2015 Senior secured credit facility, carrying value(1) $ 410.0 $ 639.5 Convertible senior notes, carrying value of liability component 1,024.8 982.5 Other 13.1 — Total 1,447.9 1,622.0 Less: current portion 9.5 229.5 Long-term portion $ 1,438.4 $ 1,392.5 (1) On February 15, 2017, the Company entered into a new credit facility and repaid the $410.0 million outstanding balance under its senior secured credit facility, as described in Note 15, Subsequent Events Debt 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. 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 on the Company’s consolidated balance sheets 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 was a part of the Credit Facility and was in addition to the Company’s current 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. These debt issuance costs were recorded on the Company’s consolidated balance sheets and amortized over the life of the Term Loan. The Term Loan matured on March 9, 2016 and was repaid in full. 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 senior notes described below and the capped call and prepaid forward share repurchase transactions described in greater detail in Note 8, Shareholders’ (Deficit) Equity On May 4, 2015, the Company amended its Credit Facility to extend the maturity date of its 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 the Term Loan and revolving credit facility, respectively. Additionally, the Company’s $700 million borrowing capacity on its 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. The total available borrowing capacity under the revolving credit facility was $425.0 million as of December 31, 2016. Prior to March 9, 2016, the interest rates on the Company’s borrowings under the 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 Credit Facility increased by 2.00% such that borrowings under the Credit Facility now bear 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. The debt issuance costs are recorded on the Company’s consolidated balance sheets and are being amortized over the life of the revolving credit facility. The base rate under the Credit Facility represents the highest of the Federal Funds Rate plus 0.50%, the 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 0.40% 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. All obligations under the Credit Facility are unconditionally guaranteed by certain of the Company’s subsidiaries and are secured by substantially all of the assets of the U.S. subsidiaries of the parent company, Herbalife Ltd. and by certain assets of certain foreign subsidiaries of Herbalife Ltd. 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. The Credit Facility restricts the Company’s ability to pay dividends or repurchase its common shares to a maximum of $233.0 million until maturity and for every one dollar of share repurchase or dividend paid, the revolving credit facility’s borrowing capacity is permanently decreased by two dollars. The Credit Facility also provides for the grant of security interest on certain additional assets of the Company and its subsidiaries. The Company is also required to maintain a minimum balance of $200.0 million of consolidated cash and cash equivalents. As of December 31, 2016 and 2015, the Company was compliant with its debt covenants under the Credit Facility. On December 31, 2016 and December 31, 2015, the weighted-average interest rate for borrowings under the Credit Facility was 4.29% and 2.78%, respectively. During 2016, the Company borrowed an aggregate amount of $200.0 million and paid a total amount of $429.7 million under the Credit Facility. During 2015, the Company did not make any borrowings and paid a total amount of $210.3 million under the Credit Facility. During 2014, the Company borrowed an aggregate amount of $50.0 million and paid a total amount of $131.3 million under the Credit Facility. As of December 31, 2016, the U.S. dollar amount outstanding under the revolving credit facility was $410.0 million. As of December 31, 2015, the U.S. dollar amount outstanding under the Credit Facility was $639.7 million, which consisted of $229.7 million outstanding on the Term Loan and $410.0 million outstanding on the revolving credit facility. There were no outstanding foreign currency borrowings as of December 31, 2016 and December 31, 2015 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 December 31, 2016 and 2015, 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 13, Fair Value Measurements 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 are senior unsecured obligations which rank effectively subordinated to any of our 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 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, or 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 the Company’s 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 issuance costs during the first quarter of 2014 relating to the issuance of the Convertible Notes. Of the $26.6 million issuance costs incurred, $21.5 million and $5.1 million were recorded as debt issuance costs and as additional paid-in capital, respectively, in proportion to the allocation of the proceeds of the Convertible Notes. The $21.5 million of debt issuance costs recorded 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 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 December 31, 2016, the outstanding principal on the Convertible Notes was $1.15 billion, the unamortized debt discount and debt issuance costs was $125.2 million, and the carrying amount of the liability component was $1,024.8 million, which was recorded to long-term debt within the Company’s consolidated balance sheet as reflected in the table above within this Note. As of December 31, 2015, the outstanding principal on the Convertible Notes was $1.15 billion, the unamortized debt discount and debt issuance costs was $167.6 million, and the carrying amount of the liability component was $982.5 million, which was recorded to long-term debt within the Company’s consolidated balance sheet as reflected in the table above within this Note. As of December 31, 2016, the fair value of the liability component relating to the Convertible Notes was approximately $961.3 million. As of December 31, 2015, the fair value of the liability component relating to the Convertible Notes was approximately $795.9 million. At December 31, 2016 and 2015, the Company determined the fair value of the liability component of the 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 Convertible Notes. Most of these inputs are primarily considered Level 2 and Level 3 inputs. 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. 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 8, Shareholders’ (Deficit) Equity During the years ended December 31, 2016, 2015, and 2014, the Company recognized $65.3 million, $61.7 million, and $55.1 million of interest expense relating to the Convertible Notes, respectively, which included $38.6 million, $35.7 million, and $30.8 million relating to non-cash interest expense relating to the debt discount, respectively, and $3.8 million, $3.2 million, $3.3 million relating to amortization of deferred financing costs, respectively. The Company’s total interest expense, including the Credit Facility, was $99.3 million, $100.5 million, and $91.7 million, for the years ended December 31, 2016, 2015, and 2014, respectively, which was recognized within its consolidated statement of income. As of December 31, 2016, annual scheduled principal payments of debt were: $419.5 million; $2.9 million; $1,150.4 million; and $0.3 million for the years ended December 31, 2017, 2018, 2019 and 2020, respectively. Certain vendors and government agencies may require letters of credit or similar guaranteeing arrangements to be issued or executed. As of December 31, 2016, the Company had $36.7 million of issued but undrawn letters of credit or similar arrangements, which included the Mexico 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 $4.8 million, $4.3 million, and $3.5 million during the years ended December 31, 2016, 2015, and 2014, 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 $5.8 million, $5.5 million, and $7.5 million for the years ended December 31, 2016, 2015, and 2014, 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 expense for the two non-qualified deferred compensation plans, excluding participant contributions, was $3.6 million, $0.1 million, and $1.7 million for the years ended December 31, 2016, 2015, and 2014, respectively. The total long-term deferred compensation liability under the two deferred compensation plans was $50.0 million and $43.6 million at December 31, 2016 and 2015, respectively. 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 $30.6 million and $29.3 million as of December 31, 2016 and 2015, respectively.

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. Tax Matters On May 7, 2010, the Company received an assessment from the Mexican Tax Administration Service in an amount equivalent to approximately $56 million, translated at the December 31, 2016 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. Litigation of the appeal is ongoing. The Company believes that it has meritorious defenses if the assessment is reissued. The Company has not recognized a loss as the Company does not believe a loss is probable. 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 $14.2 million, translated at the December 31, 2016 spot rate, related to that period. 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. The Company issued a surety bond in the amount of $15.8 million, translated at the December 31, 2016 spot rate, through an insurance company to guarantee payment of the tax assessment as required while the Company pursues an appeal of the assessment. Litigation in this case is currently ongoing. The Company has not recognized a loss as the Company does not believe a loss is probable. The Mexican Customs Service has challenged the customs classification codes used by the Company for certain importations. A change in the customs classification codes would require the payment of additional VAT and other taxes for those importations. The Company believes that the customs classification codes used for the importation of these products were correct and has generally prevailed in such cases through an administrative appeal. The Company expects to challenge any further assessments as they are received. Most of the products that were the subject of the dispute have since been reformulated to avoid potential additional assessments related to future importations of product. 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. In March 2015, the Company commenced litigation in the Tax Court of Mexico to reclaim the VAT refund pertaining specifically to the July 2013 period. In July 2016, the Company withdrew its VAT refund claim as it has elected to apply this immaterial amount against certain future tax liabilities. As of December 31, 2016, the Company had $44.0 million of Mexico VAT related assets, of which $35.5 million was within non-current other assets and $8.5 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. The Company has not recognized any losses related to these VAT related assets as the Company does not believe a loss is probable. On March 26, 2015, the Office of the President of Mexico issued a decree relating to the application of VAT to Nutritional Supplements. The Company continues to believe its application of the VAT law in Mexico is correct. At December 31, 2016, the Company has not recognized any losses as the Company, based on its current analysis and guidance from its advisors, does not believe a loss is probable. The Company continues to evaluate and monitor its situation as it develops, including whether it will make any changes to its operations in Mexico. The Company has not recognized a loss with respect to any of these Mexican matters as the Company, based on its analysis and guidance from its advisors, does not believe a loss is probable. Further, 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 the assessment is re-issued or would have meritorious defenses if any additional assessment is issued. As previously disclosed, the Mexican Tax Administration Service has requested information related to the Company’s 2010 year. This information has been provided and the Tax Administration Service has now completed its income tax audit related to the 2010 year. The Tax Administration Service is now discussing its preliminary findings with the Company. It is possible that the Company could receive a final assessment from the Tax Administration Service after these discussions are completed. The Company believes that it has recognized an appropriate amount of income tax expense with respect to its Mexican operations during the 2010 year. The Company believes that it has meritorious defenses if a formal assessment is issued by the Tax Administration Service. 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 Tax Administration Service. The Company received a tax assessment in September 2009 from the Federal Revenue Office of Brazil in an amount equivalent to approximately $2.2 million, translated at the December 31, 2016 spot rate, related to withholding/contributions based on payments to the Company’s Members during 2004. On December 28, 2010, the Company appealed this tax assessment to the Administrative Council of Tax Appeals (2nd level administrative appeal). The Company believes it has meritorious defenses and it has not recognized a loss as the Company does not believe a loss is probable. On March 6, 2014, the Company was notified of a similar audit of the 2011 year. In January 2016, the Company received a tax assessment for an amount equivalent to approximately $5.4 million, translated at the December 31, 2016 spot rate, related to contributions based on payments to the Company’s Members during 2011. The Company has not accrued a loss for the majority of the assessment because the Company does not believe a loss is probable. The Company filed a first level administrative appeal against most of the assessment on February 23, 2016. The Company’s Brazilian subsidiary pays ICMS-ST taxes on its product purchases, similar to VAT. The Company believes it will be able to utilize or recover these ICMS-ST credits in the future. The Company had $16.0 million, translated at the December 31, 2016 spot rate, of Brazil ICMS-ST related assets within other assets on its consolidated balance sheet. 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 Sao Paulo has audited the Company for the 2013 and 2014 tax years. During July 2016, for the State of Sao Paulo, the Company received an assessment in the aggregate amount of approximately $49.4 million, translated at the December 31, 2016 spot rate, relating to various ICMS issues for its 2013 tax year and it is possible the Company could receive a similar assessment for its 2014 tax year. In August 2016, the Company filed a first level administrative appeal which was denied in February 2017. The Company plans to file further appeals. The Company has not recognized a loss as the Company does not believe a loss is probable. The Company has also received assessments from other states in Brazil. During the fourth quarter of 2015, the Company filed appeals with state judicial courts against three of the assessments relating to other states in Brazil. The Company had issued surety bonds in the aggregate amount of $10.8 million, translated at the December 31, 2016 spot rate, through an insurance company to guarantee payment of the three 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 $9.4 million, translated at the December 31, 2016 spot rate, from several 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 $5.1 million, translated at the December 31, 2016 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 $29.7 million translated at the December 31, 2016 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. 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 of approximately $2.1 million translated at the December 31, 2016 spot rate, 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. The Company could receive similar assessments covering other years. The Company disputes the allegations raised in the assessment and intends to timely appeal the assessment. The Company has not recognized a loss as it does not believe a loss is probable. U.S. Federal Trade Commission Consent Order As previously disclosed, the Company received from the U.S. Federal Trade Commission, or the FTC, a Civil Investigative Demand, or a CID, relating to the FTC’s confidential investigation of whether the Company has complied with federal law in the advertising, marketing, or sale of business opportunities. On July 15, 2016, the Company and 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, upon final approval by the Court. 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 agreed to make, through its wholly owned subsidiary Herbalife International of America, Inc., a $200 million payment to the FTC within seven days of entry of the Consent Order. The $200 million settlement amount is recognized in selling, general and administrative expenses within the Company’s consolidated statements of income for the year ended December 31, 2016 and was paid in July 2016. Additionally, pursuant to the Consent Order, the Company has agreed to implement certain new procedures and enhance certain existing procedures in the U.S., most of which the Company will have 10 months from the Effective Date to implement. Among other requirements, 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 $15 million. The SEC and the Department of Justice have requested from the Company documents and other information relating to the Company’s anti-corruption compliance in China and the Company is conducting its own review. The Company is cooperating with the government and cannot predict the eventual scope, duration, or outcome of the matter at this time. Since late 2012, a short seller has made and continues to make allegations regarding the Company and its network marketing program. The Company believes these allegations are without merit and is vigorously defending itself against such claims, including proactively reaching out to governmental authorities about what the Company believes is manipulative activity with respect to its securities. Because of these allegations, the Company and others have received and may receive additional regulatory and governmental inquiries. For example, the Company has previously disclosed inquiries from the FTC, Securities and Exchange Commission and other governmental authorities. In the future, governmental authorities may determine to seek information from the Company and other persons relating to these same or other allegations. If the Company believes any governmental or regulatory inquiry or investigation is or becomes material it will be disclosed individually. Consistent with its policies, the Company has cooperated and will continue to fully cooperate with any governmental or regulatory inquiries or investigations. These 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.

Equity [Abstract]
Shareholders' (Deficit) Equity	8. Shareholders’ (Deficit) Equity The Company had 93.1 million, 92.7 million, and 92.2 million common shares outstanding at December 31, 2016, 2015, and 2014, 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, 2016. 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 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 Ltd.’s available distributable reserves under Cayman Islands law, restrictions imposed by the 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 Credit Facility permits payments of dividends up to a specified cap as long as no default or event of default exists and the consolidated leverage ratio specified in the Credit Facility is not exceeded. See Note 4, Long-Term Debt 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 aggregate amount of dividends paid and declared during the fiscal year ended December 31, 2014 was approximately $30.4 million. The Company did not pay or declare any dividends during the fiscal years ended December 31, 2016 and 2015. During the year ended December 31, 2014, the Company received $3.4 million of dividends primarily relating to the Forward Transactions described below which was recorded directly to its (accumulated deficit) retained earnings. The Company did not receive any dividends during the years ended December 31, 2016 and 2015. Share Repurchases On July 30, 2012, the Company announced that its board of directors authorized a new $1 billion share repurchase program that will expire on June 30, 2017. On February 3, 2014, the Company announced that its board of directors authorized an increase in the existing share repurchase authorization to an available balance of $1.5 billion. This share repurchase program allows the Company to repurchase its common shares, at such times and prices as determined by the Company’s management as market conditions warrant, and to the extent Herbalife Ltd.’s distributable reserves are available under Cayman Islands law. The Credit Facility permits the Company to repurchase its common shares up to a specified cap as long as no default or event of default exists and the consolidated leverage ratio specified in the Credit Facility is not exceeded. See Note 4, Long-Term Debt , for further information on restrictions concerning the Company’s ability to repurchase its common shares Subsequent Events senior secured credit facility 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, or the Forward Counterparties, pursuant to which the Company purchased approximately 9.9 million common shares for settlement on or around the August 15, 2019 maturity date for the 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 Convertible Notes, including swaps, relating to the common shares by which holders of the Convertible Notes establish short positions relating to the common shares and otherwise hedge their investments in the Convertible Notes concurrently with, or shortly after, the pricing of the Convertible Notes. As a result of the Forward Transactions, the Company’s total shareholders’ (deficit) equity within its consolidated balance sheet was reduced 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) retained earnings and additional paid-in-capital, respectively, within total shareholders’ (deficit) equity. 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, 2016, 2015 and 2014, the Company recognized $6.5 million, $6.5 million and $5.8 million, respectively, of non-cash interest expense within its consolidated statement of income relating to amortization of these non-cash issuance costs. On May 6, 2014, the Company entered into an agreement with Merrill Lynch International to repurchase $266.0 million of its common shares, or the Repurchase Agreement, which expired on June 30, 2014. Under the terms of the Repurchase Agreement, the Company paid $266.0 million on May 7, 2014, and received an aggregate 4.3 million of its common shares under the Repurchase Agreement during May and June 2014. The total number of common shares repurchased under the Repurchase Agreement was determined generally upon a discounted volume-weighted average share price of the Company’s common shares over the course of the Repurchase Agreement. The Company did not repurchase any of its common shares in the open market during the years ended December 31, 2016 and 2015. During the year ended December 31, 2014, the Company repurchased 19.7 million of its common shares through open market purchases, the Repurchase Agreement, and the Forward Transactions at an aggregate cost of approximately $1,267.1 million, or an average cost of $64.25 per share. The approximate 9.9 million common shares effectively repurchased through the Forward Transactions are treated as retired shares for basic and diluted EPS purposes although they remain legally outstanding. During the years ended December 31, 2016, 2015, and 2014, the Company also withheld shares on its vested RSUs and exercised SARs relating to its share-based compensation plans, which are treated as share repurchases in the Company’s consolidated financial statements as discussed further below. As of December 31, 2016, the remaining authorized capacity under the Company’s share repurchase program was $232.9 million inclusive of reductions for the Forward Transactions. The Company reflects the aggregate purchase price of its common shares repurchased as a reduction to (increase in) shareholders’ (deficit) equity. The Company allocated the purchase price of the repurchased shares to (accumulated deficit) retained earnings, common shares and additional paid-in-capital. 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 minimum 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. Capped Call Transactions In connection with the issuance of Convertible Notes, the Company 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. The Capped Call Transactions are expected generally to reduce the potential dilution upon conversion of the 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 $86.28 per common share, with such reduction of potential dilution subject to a cap based on the cap price initially set at $120.79 per common share. 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.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
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 8,700,000 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. At December 31, 2016, an aggregate of approximately 5.5 million common shares remain available for future issuance under the 2014 Stock Incentive Plan. The Company’s share-based compensation plans provide for grants of stock options, stock appreciation rights, or SARs, and stock units, which are collectively referred to herein as awards. Previously, stock options generally vested quarterly over a five-year period or less, beginning on the grant date. Certain SARs vest quarterly over a five-year period beginning on the grant date. Other SARs vest annually over a three-year period. The contractual term of service condition stock options and SARs is generally ten years. Stock unit awards under the 2014 Stock Incentive Plan, or Incentive Plan Stock Units, vest annually over a three year period. Stock units awarded 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, market and performance condition awards, or service condition awards. Unless otherwise determined at the time of grant, the value of each stock unit shall be equal to one common share of Herbalife. The Company’s stock compensation awards outstanding as of December 31, 2016 include SARs and stock units. In August 2011, the Company granted SARs with market and performance conditions to its Chairman and Chief Executive Officer. These awards were to vest on December 31, 2014, subject to his continued employment through that date, the Company’s stock price appreciating and exceeding a targeted price, and the Company’s achievement of certain Volume Point performance targets. The fair value of these SARs was determined on the date of the grant using the Monte Carlo lattice model. At the end of December 31, 2014, the Chairman and Chief Executive Office remained an employee of the Company and the Company met the specified Volume Point performance targets. As the requisite service and performance conditions were met, the impact of the share-based compensation expense recorded in connection with these SARs remained in the Company’s consolidated financial statements. However, as the price of the Company’s common shares did not exceed the target price, the applicable SARs did not vest and are no longer considered outstanding. During the years ended December 31, 2016, 2015 and 2014, the Company granted SARs with performance conditions to certain employees. These awards 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. During the years ended December 31, 2016, 2015, and 2014, 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. Stock-based compensation expense is included in selling, general and administrative expenses in the consolidated statements of income. For the years ended December 31, 2016, 2015, and 2014, share-based compensation expense relating to service condition awards amounted to $23.9 million, $26.8 million, and $27.9 million, respectively. For the years ended December 31, 2016 and 2015, share-based compensation expense relating to market condition awards amounted to $0.4 million and $0.3 million, respectively. No share-based compensation expense relating to market condition awards was recognized in the year ended December 31, 2014. For the years ended December 31, 2016, 2015 and 2014, share-based compensation expense relating to performance condition awards amounted to $15.9 million, $17.8 million, and $13.3 million, respectively. No share-based compensation expense related to market and performance condition awards was recognized in the years ended December 31, 2016 and 2015. For the year ended December 31, 2014, share-based compensation expense relating to market and performance condition awards amounted to $4.5 million. For the years ended December 31, 2016, 2015, and 2014, the related income tax benefits recognized in earnings for all awards amounted to $14.8 million, $16.6 million, and $16.6 million, respectively. As of December 31, 2016, the total unrecognized compensation cost related to non-vested service condition stock awards was $31.0 million and the related weighted-average period over which it is expected to be recognized is approximately 1.8 years. As of December 31, 2016, the total unrecognized compensation cost related to non-vested performance condition awards was $17.1 million and the related weighted-average period over which it is expected to be recognized is approximately 1.6 years. As of December 31, 2016, the total unrecognized compensation cost related to non-vested market condition stock awards was $0.5 million and the related weighted-average period over which it is expected to be recognized is approximately 1.2 years. Stock units 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 are based upon the historical volatility of the Company’s common shares and it 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 stock options granted during the years ended December 31, 2016, 2015, and 2014. There were no SARs granted to independent directors during the years ended December 31, 2016, 2015 and 2014.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	11. Derivative Instruments and Hedging Activities Foreign Currency Instruments The Company designates certain foreign currency derivatives, primarily comprised of foreign currency forward contracts, as freestanding derivatives for which hedge accounting does not apply. The changes in the fair market value of these freestanding derivatives are included in selling, general and administrative expenses in the Company’s consolidated statements of income. The Company uses freestanding foreign currency derivatives to hedge foreign-currency-denominated intercompany transactions and to partially mitigate the impact of foreign currency fluctuations. The fair value of the freestanding foreign currency derivatives is based on third-party quotes. The Company’s foreign currency derivative contracts are generally executed on a monthly basis. The Company designates as cash-flow hedges those foreign currency forward contracts it enters into to hedge forecasted inventory purchases and intercompany management fees that are subject to foreign currency exposures. Forward contracts are used to hedge forecasted inventory purchases over specific months. Changes in the fair value of these forward contracts, excluding forward points, designated as cash-flow hedges are recorded as a component of accumulated other comprehensive income (loss) within shareholders’ (deficit) equity, and are recognized in cost of sales in the consolidated statement of income during the period which approximates the time the hedged inventory is sold. The Company also hedges forecasted intercompany management fees over specific months. These contracts allow the Company to sell Euros in exchange for U.S. dollars at specified contract rates. Changes in the fair value of these forward contracts designated as cash flow hedges are recorded as a component of accumulated other comprehensive income (loss) within shareholders’ (deficit) equity, and are recognized in selling, general and administrative expenses in the consolidated statement of income during the period when the hedged item and underlying transaction affect earnings. As of December 31, 2016 and December 31, 2015, the aggregate notional amounts of all foreign currency contracts outstanding designated as cash flow hedges were approximately $90.0 million and $112.8 million, respectively. At December 31, 2016, these outstanding contracts had maturity dates of less than fifteen months. The Company’s derivative financial instruments are recorded on the consolidated balance sheets at fair value based on third-party quotes. As of December 31, 2016, the Company recorded assets at fair value of $4.6 million relating to all outstanding foreign currency contracts designated as cash-flow hedges. As of December 31, 2015, the Company recorded assets at fair value of $4.2 million and liabilities at fair value of $0.5 million relating to all outstanding foreign currency contracts designated as cash-flow hedges. The Company assesses hedge effectiveness and measures hedge ineffectiveness at least quarterly. During the years ended December 31, 2016, and 2015, the ineffective portion relating to these hedges was immaterial and the hedges remained effective as of December 31, 2016, and December 31, 2015.

Income Taxes	12. Income Taxes The components of income before income taxes are as follows (in millions): Year Ended December 31, 2016 2015 2014 Domestic $ (89.3 ) $ 80.9 $ 94.0 Foreign 454.0 405.5 327.3 Total $ 364.7 $ 486.4 $ 421.3 Income taxes are as follows (in millions): Year Ended December 31, 2016 2015 2014 Current: Foreign $ 127.9 $ 147.0 $ 141.7 Federal 12.4 35.4 47.4 State 0.8 3.1 8.3 141.1 185.5 197.4 Deferred: Foreign 12.5 (13.2 ) (6.0 ) Federal (47.2 ) (23.8 ) (76.5 ) State (1.7 ) (1.2 ) (2.3 ) (36.4 ) (38.2 ) (84.8 ) $ 104.7 $ 147.3 $ 112.6 The Company recognizes excess tax benefits associated with share-based compensation to shareholders’ (deficit) equity only when realized. When assessing whether excess tax benefits relating to share-based compensation have been realized, the Company follows the with-and-without approach. Under this approach, excess tax benefits related to share-based compensation are not deemed to be realized until after the utilization of all other tax benefits available to the Company, which are also subject to applicable limitations. As of December 31, 2016 and 2015, the Company had $29.6 million and $25.4 million, respectively, of unrealized excess tax benefits. The $29.6 million of excess tax benefits at December 31, 2016 relates to foreign tax credits generated and carried forward on U.S. federal income tax returns. If unused, tax credit carryforwards will expire between 2021 and 2026. The significant categories of temporary differences that gave rise to deferred tax assets and liabilities are as follows (tax effected in millions): December 31, 2016 2015 Deferred income tax assets: Accruals not currently deductible $ 85.2 $ 84.6 Tax loss and credit carryforwards of certain foreign subsidiaries 115.1 121.4 Tax loss and domestic tax credit carryforwards 102.6 76.7 Unremitted foreign earnings — 6.4 Deferred compensation plan 73.8 63.9 Accrued vacation 6.2 5.8 Inventory reserve 11.2 11.5 Other 2.5 3.4 Gross deferred income tax assets 396.6 373.7 Less: valuation allowance (115.4 ) (121.3 ) Total deferred income tax assets $ 281.2 $ 252.4 Deferred income tax liabilities: Intangible assets $ 112.2 $ 112.8 Depreciation/amortization 15.9 22.1 Unremitted foreign earnings 5.5 — Other 7.7 0.9 Total deferred income tax liabilities 141.3 135.8 Total net deferred tax assets $ 139.9 $ 116.6 Tax loss and credit carryforwards of certain foreign subsidiaries for 2016 and 2015 were $115.1 million and $121.4 million, respectively. If unused, tax loss and credit carryforwards of certain foreign subsidiaries of $81.5 million will expire between 2017 and 2026 and $33.6 million can be carried forward indefinitely. Domestic foreign tax credit carryforwards for 2016 and 2015 were $99.6 million and $76.7 million, respectively. If unused, domestic foreign tax credit carryforwards begin to expire in 2024. The domestic research and development tax credit carryforward for 2016 was $2.2 million. If unused, domestic research and development tax credit carryforwards will expire in 2036. The state tax loss carryforwards for 2016 were $0.8 million. If unused, state tax loss carryforwards will expire between 2021 and 2036. The Company’s net deferred tax asset year over year increase is primarily related to the increase of $22.9 million in excess foreign tax credits. This increase is mostly a result of the deduction of a settlement payment made to the Federal Trade Commission, which for US foreign tax credit purposes resulted in an overall domestic loss and limited the Company’s ability to claim foreign tax credits. In future taxable years as domestic source income is generated, 50% of such income will be reclassified as foreign source income as allowed and will increase the Company’s foreign tax credit limitation, thereby enabling the use of additional foreign tax credits. Although not certain, the Company believes that the utilization of the foreign tax credits carryforward of $99.6 million at December 31, 2016 is more likely than not. The Company does not have a history of foreign tax credits expiring. In addition, the Company expects that $25.7 million of foreign tax credits, resulting from the overall domestic loss, will be utilized as discussed above. Also, the Company believes that anticipated taxable income and, if needed, the potential implementation of tax planning strategies, such as the acceleration of foreign source income, should prevent foreign tax credit carryforwards from expiring. The Company recognizes valuation allowances on deferred tax assets reported if, based on the weight of the evidence it is more likely than not that some or all of the deferred tax assets will not be realized. As of December 31, 2016 and 2015 the Company held valuation allowances against net deferred tax assets of certain subsidiaries, primarily related to tax loss carryforwards, in the amount of $115.4 million and tax loss carryforwards of At December 31, 2016, the Company’s U.S. consolidated group had approximately $131.9 million of unremitted earnings that were permanently reinvested relating to certain foreign subsidiaries. In addition, at December 31, 2016, Herbalife Ltd. had approximately $2.5 billion of permanently reinvested unremitted earnings relating to its operating subsidiaries. Since these unremitted earnings have been permanently reinvested, deferred taxes were not provided on these unremitted earnings. Further, it is not practicable to determine the amount of unrecognized deferred taxes with respect to these unremitted earnings. If the Company were to remit these unremitted earnings then it would be subject to income tax on these remittances. Deferred taxes have been accrued for earnings that are not considered indefinitely reinvested. The deferred tax on the unremitted foreign earnings as of December 31, 2016 and 2015 was a deferred tax liability of $5.5 million and a deferred tax asset of $6.4 million, respectively. The applicable statutory income tax rate in the Cayman Islands was zero for Herbalife Ltd. for the years being reported. For purposes of the reconciliation between the provision for income taxes at the statutory rate and the provision for income taxes at the effective tax rate, a notional 35% tax rate is applied as follows: Year Ended December 31, 2016 2015 2014 (In millions) Tax expense at United States statutory rate $ 127.7 $ 170.2 $ 147.4 Increase (decrease) in tax resulting from: Differences between U.S. and foreign tax rates on foreign income, including withholding taxes (16.6 ) 203.1 (60.0 ) U.S. tax (benefit) on foreign income net of foreign tax credits (10.2 ) (23.9 ) (73.4 ) (Decrease) increase in valuation allowances (5.6 ) (205.6 ) 85.7 State taxes, net of federal benefit 0.3 1.7 4.1 Unrecognized tax benefits 5.3 10.1 13.0 Other 3.8 (8.3 ) (4.2 ) Total $ 104.7 $ 147.3 $ 112.6 As of December 31, 2016, the total amount of unrecognized tax benefits, including related interest and penalties was $62.0 million. If the total amount of unrecognized tax benefits was recognized, $44.8 million of unrecognized tax benefits, $9.4 million of interest and $2.1 million of penalties would impact the effective tax rate. As of December 31, 2015, the total amount of unrecognized tax benefits, including related interest and penalties was $58.0 million. If the total amount of unrecognized tax benefits was recognized, $44.1 million of unrecognized tax benefits, $7.1 million of interest and $1.5 million of penalties would impact the effective tax rate. The Company accounts for the interest and penalties generated by tax contingencies as a component of income tax expense. During the year ended December 31, 2016, the Company recorded an increase in interest and penalty expense related to uncertain tax positions of $2.7 million and $0.7 million, respectively. During the year ended December 31, 2015, the Company recorded an increase in interest and penalty expense related to uncertain tax positions of $2.0 million and $0.6 million, respectively. During the year ended December 31, 2014, the Company recorded an increase in interest and penalty expense related to uncertain tax positions of $1.9 million and $0.3 million, respectively. As of December 31, 2016, total amount of interest and penalties related to unrecognized tax benefits recognized in the statement of financial position were $9.4 million and $2.1 million, respectively. As of December 31, 2015, total amount of interest and penalties related to unrecognized tax benefits recognized in the statement of financial position were $7.1 million and $1.5 million, respectively. As of December 31, 2014, total amount of interest and penalties related to unrecognized tax benefits recognized in the statement of financial position were $5.5 million and $1.1 million respectively. The following changes occurred in the amount of unrecognized tax benefits during the years ended December 31, 2016, 2015, and 2014 (in millions): Year Ended December 31 2016 Year Ended December 31 2015 Year Ended December 31 2014 Beginning balance of unrecognized tax benefits $ 49.4 $ 40.5 $ 29.9 Additions for current year tax positions 9.3 11.3 9.4 Additions for prior year tax positions 2.0 2.5 6.1 Reductions for prior year tax positions (4.7 ) (0.6 ) (1.0 ) Reductions for audit settlements — (0.1 ) (0.1 ) Reductions for the expiration of statutes of limitation (4.2 ) (2.8 ) (2.5 ) Changes due to foreign currency translation adjustments (1.3 ) (1.4 ) (1.3 ) Ending balance of unrecognized tax benefits (excluding interest and penalties) $ 50.5 $ 49.4 $ 40.5 Interest and penalties associated with unrecognized tax benefits 11.5 8.6 6.7 Ending balance of unrecognized tax benefits (including interest and penalties) $ 62.0 $ 58.0 $ 47.2 The amount of income taxes the Company pays is subject to ongoing audits by taxing jurisdictions around the world. The Company’s estimate of the potential outcome of any uncertain tax position is subject to management’s assessment of relevant risks, facts, and circumstances existing at that time. The Company believes that it has adequately provided for these matters. However, the Company’s future results may include favorable or unfavorable adjustments to its estimates in the period the audits are resolved, which may impact the Company’s effective tax rate. As of December 31, 2016, the Company’s tax filings are generally subject to examination in major tax jurisdictions for years ending on or after December 31, 2009. The Company believes that it is reasonably possible that the amount of unrecognized tax benefits could decrease by up to approximately $11.0 million within the next twelve months. Of this possible decrease, $5.5 million would be due to the settlement of audits or resolution of administrative or judicial proceedings. The remaining possible decrease of $5.5 million would be due to the expiration of statute of limitations in various jurisdictions.

Professional Fees and Other Expenses	14. Professional Fees and Other Expenses In late 2012, a hedge fund manager publicly raised allegations regarding the legality of the Company’s network marketing program and announced that the hedge fund manager had taken a significant short position regarding the Company’s common shares, leading to intense public scrutiny and significant stock price volatility. The Company believes that the hedge fund manager’s allegations are inaccurate and misleading. The Company has engaged legal and advisory firms to assist with responding to the allegations and to perform other related services in connection to these recent events. The Company recognizes the related expenses as a part of selling, general and administrative expenses within its consolidated statement of income. For the years ended December 31, 2016, 2015, and 2014, the Company recorded approximately $12.1 million, $18.7 million, and $25.1 million, respectively, of professional fees and other expenses related to this matter.

Subsequent Events [Abstract]
Subsequent Events	15. Subsequent Events On February 15, 2017, the Company entered into a $1,450.0 million senior secured credit facility, or the New Credit Facility, consisting of a Term Loan Facility in an initial aggregate principal amount of $1,300.0 million and a Revolving Facility in an initial aggregate principal amount of $150.0 million with a syndicate of financial institutions as lenders, or Lenders. The Term Loan Facility was issued to the Lenders at a 2% discount, or $26.0 million, and the Company estimates its debt issuance cost in connection with the New Credit Facility to be approximately $23 million. The Company also repaid the $410.0 million outstanding balance on its prior Credit Facility as disclosed in Note 4, Long-Term Debt The Revolving Facility matures on February 15, 2022 and the Term Loan Facility matures on February 15, 2023. The New Credit Facility permits the Company to borrow in U.S. dollars and, subject to certain limitations, in Euros. Borrowings under the Term Loan Facility will bear interest at either the eurocurrency rate plus a margin of 5.50% or the base rate plus a margin of 4.50%. Depending on Herbalife’s total leverage ratio, borrowings under the Revolving Facility will 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%, and will initially bear interest at the eurocurrency rate plus a margin of 4.75% or the base rate plus a margin of 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. The base rate has a floor of 1.75%. The eurocurrency rate will be based on adjusted LIBOR and have a floor of 0.75%. The Company will pay a commitment fee on the Revolving Facility of 0.50% per annum on the undrawn portion of the Revolving Facility. The New Credit Facility contains affirmative, negative and financial covenants customary for financings of this type, including, among other things, limitations or prohibitions on 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 New Credit Facility contains customary events of default. On February 21, 2017, the Company’s board of directors approved a new three-year $1.5 billion share repurchase program.

Accounting Policies [Abstract]
New Accounting Pronouncements	New Accounting 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) In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date , which deferred the effective date of ASU No. 2014-09 for all entities by one year to annual reporting periods beginning after December 15, 2017. In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers (Topic 606), Principal versus Agent Considerations (Reporting Revenue versus Net) , which clarifies the implementation guidance on principal versus agent considerations in the new revenue recognition standard. ASU 2016-08 clarifies how an entity should identify the unit of accounting (i.e. the specified good or service) for the principal versus agent evaluation and how it should apply the control principle to certain types of arrangements. In April 2016, the FASB issued ASU 2016-10, Revenue from Contracts with Customers (Topic 606), Identifying Performance Obligations and Licensing , which clarifies the implementation guidance on how an entity should identify performance obligations in contracts with customers, and how it should account for licensing arrangements with customers. In May 2016, the FASB issued ASU 2016-12, Narrow-Scope Improvements and Practical Expedients , 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 In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements — Going Concern (Subtopic 205-40) In July 2015, the FASB issued ASU No. 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements. In November 2015, the FASB issued ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes 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 In February 2016, the FASB issued ASU No. 2016-02, Leases (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.

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, 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.

Consolidation Policy	Consolidation Policy The consolidated financial statements include the accounts of Herbalife Ltd. and its subsidiaries. All significant intercompany transactions and accounts have been eliminated.
Foreign Currency Translation and Transactions	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
Forward Exchange Contracts and Interest Rate Swaps	Forward Exchange Contracts and Interest Rate Swaps 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 also previously entered into interest rate swaps in managing its interest rate risk on its variable rate credit facility. The Company does not use the contracts for trading purposes. In accordance with FASB Accounting Standards Codification, or ASC, Topic 815, Derivatives and Hedging
Cash and Cash Equivalents	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, 2016 and December 31, 2015, the Company did not owe any amounts to this financial institution.
Accounts Receivable	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 $51.8 million and $49.3 million as of December 31, 2016 and 2015, respectively. Substantially all of the receivables from credit card companies were current as of December 31, 2016 and 2015. Although receivables from importers can be significant, 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, 2016, 2015, and 2014, the Company recorded $1.0 million, $3.7 million, and $2.2 million, respectively, in bad-debt expense related to allowances for the Company’s receivables. As of December 31, 2016 and 2015, the Company’s allowance for doubtful accounts was $1.3 million and $1.5 million, respectively. As of December 31, 2016 and 2015, the majority of the Company’s total outstanding accounts receivable were current.
Fair Value of Financial Instruments	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 available-for-sale investments are based on prices of similar assets traded in active markets and observable yield curves; • The fair value of option and forward contracts are based on dealer quotes; and • The Company’s variable rate revolving credit facility is recorded at carrying value and is considered to approximate its fair value. The Company’s convertible senior notes issued in February 2014, or the Convertible Notes, are recorded at carrying value, and their fair value is determined 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 Notes trading price, volatility and dividend yield as of December 31, 2016, 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 Convertible Notes. See Note 4, Long-Term Debt
Inventories	Inventories Inventories are stated at the lower of cost (primarily on the first-in, first-out basis) and net realizable value.
Debt Issuance Costs	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 $7.9 million, $8.5 million, and $6.8 million for the years ended December 31, 2016, 2015 and 2014, respectively. As of December 31, 2016 and 2015, the Company’s remaining unamortized debt issuance cost was $11.9 million and $19.8 million, respectively.
Long-Lived Assets	Long-Lived Assets At December 31, 2016 and 2015, the Company’s net property, plant and equipment consisted of the following (in millions): December 31, 2016 2015 Property, plant and equipment — at cost: Land and Building $ 51.0 $ 22.2 Furniture and fixtures 25.9 25.0 Equipment 719.8 652.4 Building and leasehold improvements 185.7 177.0 982.4 876.6 Less: accumulated depreciation and amortization (604.4 ) (537.4 ) Net property, plant and equipment $ 378.0 $ 339.2 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, 2016 and 2015, these amounts have been reflected in property, plant and equipment on the Company’s accompanying consolidated balance sheets. Depreciation of furniture, fixtures, and equipment (includes 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, was $145.7 million and $140.2 million as of December 31, 2016 and 2015, 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 $80.7 million, $82.5 million, and $81.5 million, for the years ended December 31, 2016, 2015, and 2014, 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 Intangible Assets	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 uses 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 uses 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, 2016, 2015, and 2014, there were no additions to goodwill or marketing related intangible assets or impairments of goodwill or marketing related intangible assets. At December 31, 2016 and 2015, 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, 2016 and 2015, the goodwill balance was $89.9 million and $91.8 million, respectively. The decreases in goodwill during the years ended December 31, 2016 and 2015 were due to cumulative translation adjustments.
Other Assets	Other Assets Other assets on the Company’s accompanying consolidated balance sheets include long-term deferred tax assets of $155.2 million and $7.8 million at December 31, 2016 and 2015, respectively. As noted above in Note 2, Basis of Presentation , the
Income Taxes	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. See Note 12, Income Taxes,
Royalty Overrides	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.
Comprehensive Income	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. Components of accumulated other comprehensive income (loss) consisted of the following (in millions): December 31, 2016 2015 2014 Foreign currency translation adjustment, net of tax $ (215.5 ) $ (183.0 ) $ (96.4 ) Unrealized gain on derivatives, net of tax 10.4 17.4 18.0 Unrealized gain on available-for-sale investments, net of tax — 0.1 0.2 Total accumulated other comprehensive loss $ (205.1 ) $ (165.5 ) $ (78.2 )
Operating Leases	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	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.
Professional Fees	Professional Fees The Company expenses professional fees, including legal fees, as incurred. These professional fees are included in selling, general and administrative expenses in the Company’s consolidated statements of income.
Advertising	Advertising Advertising costs, including Company sponsorships, are expensed as incurred and amounted to approximately $64.8 million, $66.1 million, and $69.7 million for the years ended December 31, 2016, 2015, and 2014, respectively. These expenses are included in selling, general and administrative expenses in the accompanying consolidated statements of income.
Earnings Per Share	Earnings Per Share Basic earnings per share represents net income for the period common shares were outstanding, 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 options, SARs and stock units. The following are the common share amounts used to compute the basic and diluted earnings per share for each period (in millions): Year Ended December 31, 2016 2015 2014 Weighted average shares used in basic computations 83.0 82.6 86.3 Dilutive effect of exercise of equity grants outstanding 3.1 2.7 4.5 Weighted average shares used in diluted computations 86.1 85.3 90.8 There were an aggregate of 4.5 million, 5.4 million, and 2.7 million of equity grants, consisting of stock options, SARs, and stock units that were outstanding during the years ended December 31, 2016, 2015, and 2014, 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 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 initial conversion price of $86.28 per share. For the years ended December 31, 2016, 2015, and 2014, the 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 Convertible Notes exceeded the average market price of the Company’s common shares for the years ended December 31, 2016, 2015, and 2014. The initial conversion rate and conversion price is described further in Note 4, Long-Term Debt The Capped Call Transactions executed in connection with the issuance of the Convertible Notes are excluded from the calculation of diluted earnings per share because their impact is always anti-dilutive.
Revenue Recognition	Revenue Recognition The Company generally recognizes revenue upon delivery and when both the title and risk and rewards pass to the Member or importer, or as products are sold
Non-Cash Investing and Financing Activities	Non-Cash Investing and Financing Activities During the years ended December 31, 2016, 2015 and 2014, the Company recorded $12.7 million, $12.3 million, and $12.3 million, respectively, of non-cash capital expenditures. In addition, during the year ended December 31, 2015, the Company recorded $15.0 million of a non-cash release of deposits in escrow that were used to reduce the Company’s accrued expense liability. During the years ended December 31, 2016 and 2015, the Company recorded $20.8 million and $17.3 million of non-cash borrowings that were used to finance software maintenance. Additionally, see Note 8, Shareholders’ (Deficit) Equity
Share-Based Payments	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	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.
