Note 1.  General

 

Amphastar Pharmaceuticals, Inc., a California corporation, was incorporated in February 1996 and merged with and into Amphastar Pharmaceuticals, Inc., a Delaware corporation, in July 2004 (together with its subsidiaries, hereinafter referred to as “the Company”). The Company is a specialty pharmaceutical company that primarily develops, manufactures, markets, and sells generic and proprietary injectable, inhalation, and intranasal products, including products with high technical barriers to market entry. Additionally, the Company sells insulin active pharmaceutical ingredient, or API, products. Most of the Company’s products are used in hospital or urgent care clinical settings and are primarily contracted and distributed through group purchasing organizations and drug wholesalers. The Company’s insulin API products are sold to other pharmaceutical companies for use in their own products and are being used by the Company in the development of injectable finished pharmaceutical products. The Company’s inhalation products will be primarily distributed through drug retailers when they are brought to market.

 

The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements of the Company for the year ended December 31, 2017, and the notes thereto as filed with the Securities and Exchange Commission, or SEC, in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with generally accepted accounting principles, or GAAP, have been condensed or omitted from the accompanying condensed consolidated financial statements. The accompanying year-end condensed consolidated balance sheet was derived from the audited financial statements. The accompanying interim financial statements are unaudited, but reflect all adjustments which are, in the opinion of management, necessary for a fair statement of the Company’s consolidated financial position, results of operations, comprehensive income (loss) and cash flows for the periods presented. Unless otherwise noted, all such adjustments are of a normal, recurring nature. The Company’s results of operations, comprehensive income (loss) and cash flows for the interim periods are not necessarily indicative of the results of operations and cash flows that it may achieve in future periods.

 

Note 2.  Summary of Significant Accounting Policies

 

Basis of Presentation

 

The unaudited condensed consolidated financial statements include the accounts of the Company and its subsidiaries, and are prepared in accordance with the requirements of the SEC for interim reporting. The Company’s subsidiaries include: (1) International Medication Systems, Limited, or IMS, (2) Armstrong Pharmaceuticals, Inc., or Armstrong, (3) Amphastar Nanjing Pharmaceuticals Inc., or ANP, (4) Nanjing Letop Fine Chemistry Co., Ltd., or Letop, (5) Nanjing Hanxin Pharmaceutical Technology Co., Ltd, or Hanxin, (6) Nanjing Baixin Trading Co. Ltd., or Baixin, (7) Amphastar France Pharmaceuticals, S.A.S., or AFP, (8) Amphastar UK Ltd., or AUK, and (9) International Medication Systems (UK) Limited, or IMS UK.

 

In July 2018, ANP completed a private placement of its common equity interest to accredited investors for aggregate gross proceeds of approximately $57.2 million, of which $26.2 million has been received by ANP as of September 30, 2018. The investors are required to complete their contributions in cash by December 31, 2018. The Company has retained approximately 58% of the equity interest in ANP immediately after the private placement and continues to consolidate the financial results of ANP with the Company’s results of operations. ANP’s net income or loss after July 2, 2018, was attributed to the Company in accordance with the Company’s equity interest of approximately 58% in ANP.

 

During the quarter ended September 30, 2018, the Company identified errors in its accounting primarily related to the depreciation of certain leasehold improvements within property, plant and equipment. The errors were not material to any of the Company’s prior period annual or interim financial statements. However, for comparative purposes, the Company has revised the prior period condensed consolidated financial statements included herein. As a result, the net income for the three and nine months ended September 30, 2017 was reduced by $0.1 million and $0.2 million, respectively. The

errors did not result in a change to the basic or diluted net income per share for the three months ended September 30, 2017. The basic net income per share for the nine months ended September 30, 2017, was reduced by $0.01. The error did not result in a change to the diluted net income per share for the nine months ended September 30, 2017. The balances of property, plant, and equipment, net and retained earnings as of December 31, 2017, were reduced by $4.8 million and $3.6 million, respectively. The error did not result in a change to the net cash provided by operating activities in the Company’s condensed consolidated statement of cash flows for the nine months ended September 30, 2017. The Company will revise additional financial statements and disclosures as applicable in future filings.

 

Use of Estimates

 

The preparation of condensed consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results could differ from those estimates. The principal accounting estimates include determination of allowances for doubtful accounts and discounts, provision for chargebacks and rebates, provision for product returns, adjustment of inventory to their net realizable values, impairment of long-lived and intangible assets and goodwill, self-insured claims, workers’ compensation liabilities, litigation reserves, stock price volatilities for share-based compensation expense, valuation allowances for deferred tax assets, and liabilities for uncertain income tax positions.

 

Foreign Currency

 

The functional currency of the Company, its domestic subsidiaries, its Chinese subsidiary, ANP, and its U.K. subsidiary, AUK, is the U.S. dollar, or USD. ANP maintains its books of record in Chinese Yuan. These books are remeasured into the functional currency of USD using the current or historical exchange rates. The resulting currency remeasurement adjustments and other transactional foreign currency exchange gains and losses are reflected in the Company’s statements of operations. 

 

The Company’s French subsidiary, AFP, maintains its book of record in Euros. Its other Chinese subsidiaries maintain their books of record in Chinese Yuan. Its U.K. subsidiary, IMS UK, maintains its book of record in Great Britain Pounds. These local currencies have been determined to be the subsidiaries’ respective functional currencies. These books of record are translated into USD using average exchange rates during the period. Assets and liabilities are translated at the rate of exchange prevailing on the balance sheet date. Equity is translated at the prevailing rate of exchange at the date of the equity transactions. Translation adjustments are reflected in stockholders’ equity and are included as a component of other accumulated comprehensive income (loss). The unrealized gains or losses of intercompany foreign currency transactions that are of a long-term investment nature are reported in other accumulated comprehensive income (loss). The unrealized gains and losses of intercompany foreign currency transactions that are of a long-term investment nature for the three and nine months ended September 30, 2018, were $0.2 million loss and $1.0 million loss, respectively, and for the three and nine months ended September 30, 2017, were $1.1 million gain and $3.8 million gain, respectively.

 

The Company does not undertake hedging transactions to cover its foreign currency exposure.

 

Comprehensive Income (loss)

 

For the three and nine months ended September 30, 2018 and 2017, the Company included its foreign currency translation gain or loss as part of its comprehensive income (loss). 

 

Restricted Cash and Short-term Investments

 

Restricted cash and short-term investments are collateral required for the Company to effect a standby letter of credit and to qualify for workers’ compensation self-insurance and are available to meet the Company’s workers’ compensation obligations on a current basis, as needed. As of September 30, 2018 and December 31, 2017, restricted cash and short-

term investments included $1.9 million in cash and $2.3 million in certificates of deposit, respectively. The certificates of deposit have original maturities greater than three months and are classified as short-term investments.

 

Financial Instruments

 

The carrying amounts of cash and cash equivalents, short-term investments, restricted cash and short-term investments, accounts receivable, accounts payable, accrued expenses, and short-term borrowings approximate fair value due to the short maturity of these items. The majority of the Company’s long-term obligations consist of variable rate debt, and their carrying value approximates fair value as the stated borrowing rates are comparable to rates currently offered to the Company for instruments with similar maturities. The Company at times enters into fixed interest rate swap contracts to exchange the variable interest rates for fixed interest rates without the exchange of the underlying notional debt amounts. Such interest rate swap contracts are recorded at their fair values.

 

Deferred Income Taxes

 

The Company utilizes the liability method of accounting for income taxes, under which deferred taxes are determined based on the temporary differences between the financial statements and the tax basis of assets and liabilities using enacted tax rates. A valuation allowance is recorded when it is more likely than not that the deferred tax assets will not be realized. At September 30, 2018, the Company was in the process of completing its accounting for the tax effects of the enactment of the Tax Act.

 

Business Combinations

 

If an acquired set of activities and assets is capable of being operated as a business consisting of inputs and processes from the viewpoint of a market participant, the assets acquired and liabilities assumed are a business. Business combinations are accounted for using the acquisition method of accounting, which requires an acquirer to recognize the assets acquired and the liabilities assumed at the acquisition date measured at their fair values as of that date. Fair value determinations are based on discounted cash flow analyses or other valuation techniques. In determining the fair value of the assets acquired and liabilities assumed in a material acquisition, the Company may utilize appraisals from third party valuation firms to determine fair values of some or all of the assets acquired and liabilities assumed, or may complete some or all of the valuations internally. In either case, the Company takes full responsibility for the determination of the fair value of the assets acquired and liabilities assumed. The value of goodwill reflects the excess of the fair value of the consideration conveyed to the seller over the fair value of the net assets received.

 

Acquisition-related costs that the Company incurs to effect a business combination are expensed in the periods in which the costs are incurred. When the operations of the acquired businesses were not material to the Company’s condensed consolidated financial statements, no pro forma presentations were disclosed.

 

Recent Accounting Pronouncements

 

In February 2016, the Financial Accounting Standards Board, or FASB, issued ASU No. 2016-02, Leases, that is aimed at making leasing activities more transparent and comparable, and which requires substantially all leases be recognized by lessees on their balance sheets as a right-of-use asset and corresponding lease liability, including leases currently accounted for as operating leases. The ASU and the related clarifications subsequently issued by the FASB will become effective for the Company’s interim and annual reporting periods during the year ending December 31, 2019, and all annual and interim reporting periods thereafter. Early adoption is permitted. The Company is required to use a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements for the reporting periods in which the guidance is adopted. While the Company continues to evaluate the provisions of ASC 842 to determine how it will be affected, the primary effect of adopting the new standard will be to record right-to-use assets and obligations for current operating leases on its consolidated financial statements. Note 16

provides details on the Company’s current operating lease arrangements. The adoption of ASC 842 is not expected to have a material impact on the Company’s results of operations or cash flows.

 

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses, which is aimed at providing financial statement users with more useful information about the expected credit losses on financial instruments and other commitments to extend credit. The standard update changes the impairment model for financial assets measured at amortized cost, requiring presentation at the net amount expected to be collected. The measurement of expected credit losses requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. Available-for-sale debt securities with unrealized losses will be recorded through an allowance for credit losses. The guidance is effective for the Company’s interim and annual reporting periods during the year ending December 31, 2020. Early adoption is permitted for interim or annual periods after December 31, 2019. The Company will be required to apply the standard’s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. The Company does not believe the adoption of this accounting guidance will have a material impact on its consolidated financial statements and related disclosures.

 

In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Test for Goodwill Impairment, which eliminates the requirement to calculate the implied fair value of goodwill. An entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The update also eliminated the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. An entity is required to disclose the amount of goodwill allocated to each reporting unit with a zero or negative carrying amount of net assets. The guidance is effective for the Company’s interim and annual reporting periods during the year ending December 31, 2020, and applied on a prospective basis. Early adoption is permitted for interim and annual goodwill impairment testing dates after January 1, 2017. The Company currently does not believe that the adoption of this accounting guidance will have a material impact on its consolidated financial statements and related disclosures.

 

In August 2017, the FASB issued ASU No. 2017-12, Targeted Improvements to Accounting for Hedging Activities, which amends the hedge accounting model in ASC 815 to enable entities to better portray the economics of their risk management activities in the financial statements and enhance the transparency and understandability of hedge results. The amendments also simplify the application of hedge accounting in certain situations. The new guidance is effective for the Company’s interim and annual reporting periods during the year ending December 31, 2019. Early adoption is permitted. The Company does not believe that the adoption of this accounting guidance will have a material impact on its consolidated financial statements and related disclosures.

 

In February 2018, the FASB issued ASU No. 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which allows entities to reclassify from accumulated other comprehensive income to retained earnings stranded tax effects resulting from the Tax Act. The guidance is effective for the Company’s interim and annual reporting periods during the year ending December 31, 2019. Early adoption is permitted. The Company does not believe that the adoption of this accounting guidance will have a material impact on its consolidated financial statements and related disclosures.

 

In June 2018, the FASB issued ASU No. 2018-07, Improvements to Non-employee Share-Based Payment Accounting, which simplifies the accounting for share-based payments to non-employees by aligning it with the accounting for share-based payments to employees. The Company early adopted the guidance on July 1, 2018. The adoption did not have a material impact on its consolidated financial statements and related disclosures.

 

In August 2018, the FASB issued ASU No. 2018-13, Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement, which removes, modifies, and adds certain disclosure requirements to ASC 820, Fair Value

Measurement. The guidance is effective for the Company’s interim and annual reporting periods during the year ending December 31, 2020. Early adoption is permitted. The Company does not believe that the adoption of this accounting guidance will have a material impact on its consolidated financial statements and related disclosures.

 

In August 2018, the FASB issued ASU No. 2018-14, Disclosure Framework – Changes to the Disclosure Requirements for Defined Benefit Plans, which removes, modifies, and adds certain disclosure requirements to ASC 715-20, Defined Benefit Plans. The guidance is effective for the Company’s interim and annual reporting periods during the year ending December 31, 2021. Early adoption is permitted. The Company does not believe that the adoption of this accounting guidance will have a material impact on its consolidated financial statements and related disclosures.

 

In October 2018, the FASB issued ASU No. 2018-17, Targeted Improvements to Related Party Guidance for Variable Interest Entities, which requires indirect interests held through related parties in common control arrangements be considered on a proportional basis for determining whether fees paid to decision makers and service providers are variable interests. The guidance is effective for the Company’s interim and annual reporting periods during the year ending December 31, 2020. Early adoption is permitted. The Company currently does not believe that the adoption of this accounting guidance will have a material impact on its consolidated financial statements and related disclosures.

 

In November 2018, the FASB issued ASU No. 2018-18, Clarifying the Interaction between Topic 808 and Topic 606, which requires transactions in collaborative arrangements to be accounted for under ASC 606, Revenue from Contracts with Customers, or ASC 606, if the counterparty is a customer for a good or service that is a distinct unit of account. The amendments also preclude entities from presenting consideration from transactions with a collaborator that is not a customer together with revenue recognized from contracts with customers. The guidance is effective for the Company’s interim and annual reporting periods during the year ending December 31, 2020. Early adoption is permitted, including in any interim period.  The Company is currently evaluating the impact that the adoption of this guidance will have on its consolidated financial statements and related disclosures.

 

Note 3.  Revenue Recognition

 

In 2018, the Company adopted ASC 606 using the modified retrospective transition method. The adoption of ASC 606 did not have a material impact on the Company’s revenue recognition or on the condensed consolidated financial statements and related disclosures. Subsequent to the adoption of ASC 606 revenue is recognized at the time that the Company’s customers obtain control of the promised goods. Revenues derived from contract manufacturing services are recognized when third-party products are shipped to customers, after the customer has accepted test samples of the products to be shipped. The results for the reporting period beginning after January 1, 2018, are presented in accordance with the new standard, although comparative information continues to be reported under the accounting standards and policies in effect for those periods. For the accounting policy related to revenue recognition for the years ended prior to and on December 31, 2017, see Note 4, Revenue Recognition, to the consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2017.

 

The Company only records revenue to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved, by estimating and recording reductions to revenue for discounts, product returns, and pricing adjustments, such as wholesaler chargebacks and retailer rebates, in the same period that the related revenue is recorded.

 

Provision for Chargebacks and Rebates

 

The provision for chargebacks and rebates is a significant estimate used in the recognition of revenue. Wholesaler chargebacks relate to sales terms under which the Company agrees to reimburse wholesalers for differences between the gross sales prices at which the Company sells its products to wholesalers and the actual prices of such products that wholesalers resell under the Company’s various contractual arrangements with third parties such as hospitals and group

purchasing organizations in the United States.  Rebates include primarily amounts paid to retailers, payers, and providers in the United States, including those paid to state Medicaid programs, and are based on contractual arrangements or statutory requirements. The Company estimates chargebacks and rebates using the expected value method at the time of sale to wholesalers based on wholesaler inventory stocking levels, historic chargeback and rebate rates, and current contract pricing.

 

The provision for chargebacks and rebates is reflected in net revenues. The following table is an analysis of the chargeback and rebate provision:

 

 

Changes in the chargeback provision from period to period are primarily dependent on the Company’s sales to its wholesalers, the level of inventory held by wholesalers, and the wholesaler’s customer mix. Changes in the rebate provision from period to period are primarily dependent on retailer’s and other indirect customers’ purchases. The approach that the Company uses to estimate chargebacks has been consistently applied for all periods presented. Variations in estimates have been historically small. The Company continually monitors the provision for chargebacks and rebates and makes adjustments when it believes that the actual chargebacks and rebates may differ from the estimates. The settlement of chargebacks and rebates generally occurs within 30 days to 60 days after the sale to wholesalers. Accounts receivable and/or accounts payable and accrued liabilities are reduced and/or increased by the chargebacks and rebate amounts depending on whether the Company has the right to offset with the customer. Of the provision for chargebacks and rebates as of September 30, 2018 and December 31, 2017, $8.5 million and $6.8 million were included in accounts receivable, net, on the condensed consolidated balance sheets, respectively. The remaining provision of $11.9 million and $11.7 million were included in accounts payable and accrued liabilities, respectively.

 

Accrual for Product Returns

 

The Company offers most customers the right to return qualified excess or expired inventory for partial credit; however, API product sales are generally non-returnable. The Company’s product returns primarily consist of the returns of expired products from sales made in prior periods. Returned products cannot be resold. At the time product revenue is recognized, the Company records an accrual for product returns estimated using the expected value method. The accrual is based, in part, upon the historical relationship of product returns to sales and customer contract terms. The Company also assesses other factors that could affect product returns including market conditions, product obsolescence, and the introduction of new competition. Although these factors do not normally give the Company’s customers the right to return products outside of the regular return policy, the Company realizes that such factors could ultimately lead to increased returns. The Company analyzes these situations on a case-by-case basis and makes adjustments to the product return reserve as appropriate. As of September 30, 2018 and December 31, 2017, cumulative sales of approximately $0.6 million and $1.2 million, respectively, for one of the Company’s products were not recognized in revenues, due to insufficient information available to determine that a significant reversal of such amount will not occur when the uncertainty associated with the return refund is subsequently resolved.

 

The provision for product returns is reflected in net revenues. The following table is an analysis of product return liability:

 

 

Of the provision of product returns as of September 30, 2018 and December 31, 2017, $4.7 million and $4.1 million were included in accounts payable and accrued liabilities on the condensed consolidated balance sheets, respectively. The remaining provision of $2.1 million and $2.4 million were included in other long-term liabilities, respectively. For the nine months ended September 30, 2018 and 2017,  the Company’s aggregate product return rate was 1.3% and 1.2% of qualified sales, respectively.

 

Note 4.  Income (loss) per share attributable to Amphastar Pharmaceuticals, Inc. shareholders

 

Basic net income (loss) per share attributable to Amphastar Pharmaceuticals, Inc. shareholders is calculated based upon the weighted-average number of shares outstanding during the period. Diluted net income (loss) per share attributable to Amphastar Pharmaceuticals, Inc. shareholders gives effect to all potential dilutive shares outstanding during the period, such as stock options, non-vested restricted stock units, and shares issuable under the Company’s Employee Stock Purchase Plan, or ESPP.

 

For the three months ended September 30, 2018, options to purchase 1,273,884 shares of stock with a weighted-average exercise price of $20.46 per share were excluded in the computation of diluted net income per common share attributable to Amphastar Pharmaceuticals, Inc. shareholders because the effect from the assumed exercise of these options would be anti-dilutive.

 

As the Company reported a net loss for the nine months ended September 30, 2018, the diluted net loss per share attributable to Amphastar Pharmaceuticals, Inc. shareholders, as reported, equals the basic net loss per share attributable to Amphastar Pharmaceuticals, Inc. shareholders since the effect of the assumed exercise of stock options, vesting of non-vested RSUs, and issuance of common shares under the Company’s ESPP are anti-dilutive. Total stock options, non-vested RSUs, and shares issuable under the Company’s ESPP excluded from the nine months ended September 30, 2018, net loss per share were 10,646,602 stock options; 1,210,718 non-vested RSUs, and 60,854 shares issuable under the ESPP.

 

For the three and nine months ended September 30, 2017, options to purchase 1,162,850 and 2,424,430 shares of stock with a weighted-average exercise price of $27.87 per share and $21.93 per shares, respectively, were excluded in the computation of diluted net income per common share attributable to Amphastar Pharmaceuticals, Inc. shareholders because the effect from the assumed exercise of these options would be anti-dilutive.

 

The following table provides the calculation of basic and diluted net income (loss) per share attributable to Amphastar Pharmaceuticals, Inc. shareholders for each of the periods presented:

 

 

 

Note 5.  Segment Reporting

 

The Company’s business is the development, manufacture, and marketing of pharmaceutical products. The Company has established two reporting segments that each report to the Chief Operating Decision Maker, or CODM, as defined in ASC 280, Segment Reporting. The Company’s performance is assessed and resources are allocated by the CODM based on the following two reportable segments:

 

 

The finished pharmaceutical products segment manufactures, markets, and distributes enoxaparin, naloxone, phytonadione, lidocaine, medroxyprogesterone acetate, as well as various other critical and non-critical care drugs. The API segment manufactures and distributes recombinant human insulin API and porcine insulin API for external customers and internal product development.

Selected financial information by reporting segment is presented below:

 

 

The Company manages its business segments to the gross profit level and manages its operating and other costs on a company-wide basis. The Company does not identify total assets by segment for internal purposes, as the Company’s CODM does not assess performance, make strategic decisions, or allocate resources based on assets.

 

The amount of net revenues in the finished pharmaceutical product segment is presented below:

 

 

Discontinuation of epinephrine injection, USP vial product

 

In February 2017, the U.S. Food and Drug Administration, or FDA, requested the Company to discontinue the manufacturing and distribution of its epinephrine injection, USP vial product, which had been marketed under the “grandfather” exception to the FDA’s “Prescription Drug Wrap-Up” program. The Company discontinued selling this product in the second quarter of 2017. For the year ended December 31, 2017, the Company recognized $17.8 million in net revenues for the sale of this product.
