SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Consolidation: The accompanying condensed consolidated financial statements include the accounts of Akorn, Inc. and its wholly-owned domestic and foreign subsidiaries. All inter-company transactions, balances and long-term intercompany loans or notes have been eliminated in consolidation, and the financial statements of Akorn India Private Limited ("AIPL") and Akorn AG (formerly "Excelvision AG" or "Hettlingen") have been translated from Indian Rupees to U.S. Dollars and Swiss Francs to U.S. dollars, respectively, based on the currency translation rates in effect either during the period or as of the date of consolidation, as applicable. The Company has no involvement with variable interest entities. Use of Estimates: The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and 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 materially from those estimates. Significant estimates and assumptions for the Company may relate to the allowances for chargebacks, rebates and administrative fees, product returns, coupons, promotions and doubtful accounts, as well as the reserve for slow-moving and obsolete inventories, the carrying value and lives of intangible assets, the useful lives of fixed assets, the carrying value of deferred income tax assets and liabilities, the assumptions underlying share-based compensation, accrued but unreported employee benefit costs and assumptions underlying the accounting for business combinations. Revenue Recognition: Revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the sales price is fixed or determinable, and collectability is reasonably assured. Revenue from product sales are recognized when title and risk of loss have passed to the customer. Provision for estimated chargebacks, rebates and administrative fees, discounts, managed care rebates, product returns and doubtful accounts is made at the time of sale and is analyzed and adjusted, if necessary, at each balance sheet date. Freight: The Company records amounts billed to customers for shipping and handling as revenue, and records shipping and handling expense related to product sales as cost of sales. Cash and Cash Equivalents: The Company considers all unrestricted, highly liquid investments with maturity of three months or less when acquired, to be cash and cash equivalents. Accounts Receivable: Trade accounts receivables are stated at their net realizable value. The nature of the Company’s business involves, in the ordinary course, significant judgments and estimates relating to chargebacks, coupon redemption, product returns, rebates, discounts given to customers and allowances for doubtful accounts. Depending on the products, the customers, the specific terms of national supply contracts and the particular arrangements with the Company’s wholesaler customers, certain rebates, chargebacks and other credits are recorded as deductions to the Company’s trade accounts receivable. Unless otherwise noted, the provisions and allowances for the following customer deductions are reflected in the accompanying condensed consolidated financial statements as reductions of revenues and trade accounts receivable, respectively. Chargebacks : The Company enters into contractual agreements with certain third parties such as retailers, hospitals, group-purchasing organizations (“GPOs”) and managed care organizations to sell certain products at predetermined prices. Similarly, we maintain an allowance for rebates and discounts related to billbacks, wholesaler fee for service contracts, GPO administrative fees, government programs, prompt payment and other adjustments with certain customers. Most of the parties have elected to have these contracts administered through wholesalers that buy the product from the Company and subsequently sell it to these third parties. As noted elsewhere, these wholesalers represent a significant percentage of the Company’s gross sales. When a wholesaler sells products to one of these third parties that are subject to a contractual price agreement, the difference between the price paid to the Company by the wholesaler and the price under the specific contract is charged back to the Company by the wholesaler. This process typically takes no more than four to six weeks, but for some products may extend out to twelve weeks. The Company tracks sales and submitted chargebacks by product number and contract for each wholesaler. Utilizing this information, the Company estimates a chargeback percentage for each product and records an allowance as a reduction to gross sales when the Company records its sale of the products. The Company reduces the chargeback allowance when a chargeback request from a wholesaler is processed. Actual chargebacks processed by the Company can vary materially from period to period based upon actual sales volume through the wholesalers. However, the Company’s provision for chargebacks is fully reserved for at the time when sales revenues are recognized. Management obtains product inventory reports from certain wholesalers to aid in analyzing the reasonableness of the chargeback allowance and to monitor whether wholesaler inventory levels do not significantly exceed customer demand. The Company assesses the reasonableness of its chargeback allowance by applying a product chargeback percentage that is based on a combination of historical activity and future price and mix expectations to the quantities of inventory on hand at the wholesalers according to wholesaler inventory reports. In addition, the Company estimates the percentage of gross sales that were generated through direct and indirect sales channels and the percentage of contract vs. non-contract revenue in the period, as these each affect the estimated reserve calculation. In accordance with its accounting policy, the Company estimates the percentage amount of wholesaler inventory that will ultimately be sold to third parties that are subject to contractual price agreements based on a trend of such sales through wholesalers. The Company uses this percentage estimate until historical trends indicate that a revision should be made. On an ongoing basis, the Company evaluates its actual chargeback rate experience, and new trends are factored into its estimates each quarter as market conditions change. For the three months ended September 30, 2016, the Company incurred a chargeback provision of $347.1 million , or 44.1% of gross sales of $787.8 million , compared to $272.3 million , or 43.0% of gross sales of $633.6 million in the prior year period. We note that the dollar and percentage increase in the comparative period was the result of gross sale increases and product mix shifts to products with higher chargeback expense percentages. The Company ensures that this rate as a percentage of gross sales is reasonable through inspection of contractual obligations, review of historical trends and evaluation of recent activity. Furthermore, other events that could materially alter chargeback rates include: changes in product pricing as a result of competitive market dynamics or negotiations with customers, changes in demand for specific products due to external factors such as competitor supply position or consumer preferences, customer shifts in buying patterns from direct to indirect through wholesalers, which could either individually or in the aggregate increase or decrease the chargeback rate depending on the direction and velocity of the change(s). To better understand the impact of changes in chargeback reserve based on circumstances that are not fully outside of the Company’s control, for instance, the ratio of sales subject to chargeback to indirect sales, the Company performs a sensitivity analysis. Holding all other assumptions constant, for a 360 basis point (“BP”) change in the ratio of sales subject to chargeback to indirect sales would increase by $0.7 million or decrease by $2.6 million if the ratio increases or decreases, respectively. Fundamentally, the BP change calculation is determined based on the 6-month trend of the average ratio of sales subject to chargeback to indirect sales. Due to the competitive generic pharmaceutical industry and our recent experience with wholesalers’ strategy and shifts in contacted and non-contracted indirect sales, we believe that the 6-month trend of the average ratio of sales subject to chargeback to indirect sales provides a representative basis for sensitivity analysis. However, the average change in the ratio of sales subject to chargeback to indirect sales in the last 6 months is immaterial. Accordingly, the BP change calculation for September 2016 is based on the difference between the lowest and highest ratio of sales subject to chargeback to indirect sales during the last 6 months. As of and for the year to date period ended September 30, 2016, the Company determined that in order to more closely align with internal analysis of associated reserves it would adjust the allowances disclosure to separately report rebates from chargebacks and rebates for both net trade accounts receivable and gross sale adjustments and to consolidate administrative and other fees with rebates for purposes of reporting of gross to net revenue reserves. All prior period information, including as of and for the three and nine months ended September 30, 2015 have been recasted to reflect this disclosure change. Rebates, Administrative and Other Fees : The Company maintains an allowance for rebates, administrative and other fees, related to contracts and other rebate programs that it has in place with certain customers. Rebate, administrative and other fee percentages vary by product and by volume purchased by each eligible customer. The Company tracks sales by product number for each eligible customer and then applies the applicable rebate, administrative and other fee percentage, using both historical trends and actual experience to estimate its rebate, administrative fees and other allowances. The Company reduces gross sales and increases the rebate, administrative and other fees allowance by the estimated rebate, administrative and other fee amounts when the Company sells its products to eligible customers. The Company reduces these allowances when it processes a customer request for a rebate. At each balance sheet date, the Company analyzes the allowance for rebates, administrative and other fees against actual rebates processed and makes necessary adjustments as appropriate. The actual amounts processed can vary materially from period to period as discussed below. The allowances for rebates, administrative and other fees further takes into consideration price adjustments which are credits issued to reflect increases or decreases in the invoice or contract prices of the Company’s products. In the case of a price decrease, a credit may be given for product remaining in customer’s inventories at the time of the price reduction. Contractual price protection results in a similar credit when the invoice or contract prices of the Company’s products increase, effectively allowing customers to purchase products at previous prices for a specified period of time. Amounts recorded for estimated shelf-stock adjustments and price protections are based upon specified terms with direct customers, estimated changes in market prices, and estimates of inventory held by customers. The Company regularly monitors these and other factors and evaluates the reserve as additional information becomes available. Similar to rebates, the reserve for administrative and other fees represent those amounts processed related to contracts and other fee programs which have been in place with certain entities, but they are settled through cash payment to these entities and accordingly are accounted for as a current liability. Otherwise, administrative and other fees operate similarly to rebates. For the three month period ended September 30, 2016 the Company incurred a rebate, administrative and other fees provision of $130.4 million , or 16.6% of gross sales of $787.8 million , compared to $83.1 million , or 13.1% of gross sales of $633.6 million in the prior year period. We note that the dollar and percentage increase in the comparative period was the result of gross sale increases and product mix shifts to products with higher rebate, administrative and other fee expense percentages. The Company ensures that this rate as a percentage of gross sales is reasonable through inspection of contractual obligations, review of historical trends and evaluation of recent activity. Furthermore, other events that could materially alter rebate, administrative and other fee rates include: changes in product pricing as a result of competitive market dynamics or negotiations with customers, changes in demand for specific products due to external factors such as competitor supply position or consumer preferences, customer shifts in buying patterns from direct to indirect through wholesalers, which could either individually or in the aggregate increase or decrease the rebate rate depending on the direction and velocity of the change(s). To better understand the impact of changes in rebate, administrative and other fee reserves based on circumstances that are not fully outside of the Company’s control, for instance, the ratio of sales subject to rebate, administrative and other fees to indirect sales, the Company performs a sensitivity analysis. Holding all other assumptions constant, for a 360 BP change in the ratio of sales subject to rebate, administrative and other fees to indirect sales would increase by $0.1 million or decrease by $0.5 million if the ratio increases or decreases, respectively. Fundamentally, the BP change calculation is determined based on the 6-month trend of the average ratio of sales subject to rebate, administrative and other fees to indirect sales. Due to the competitive generic pharmaceutical industry and our recent experience with wholesalers’ strategy and shifts in contracted and non-contracted indirect sales, we believe that the 6-month trend of the average ratio of sales subject to rebate, administrative and other fees to indirect sales provides a representative basis for sensitivity analysis. However, the average change in the ratio of sales subject to rebate, administrative and other fees to indirect sales in the last 6 months is immaterial. Accordingly, the 360 BP change calculation for September 2016 is based on the difference between the lowest and highest ratio of sales subject to rebate, administrative and other fees to indirect sales during the last 6 months. Sales Returns: Certain of the Company’s products are sold with the customer having the right to return the product within specified periods. Provisions are made at the time of sale based upon historical experience. Historical factors such as one-time recall events as well as pending new developments like competitive product approvals or significant pricing movement that may impact the expected level of returns are taken into account to determine the appropriate reserve estimate at each balance sheet date. As part of the evaluation of the reserve required, the Company considers actual returns to date that are in process, the expected impact of any product recalls and the amount of wholesaler’s inventory to assess the magnitude of unconsumed product that may result in sales returns to the Company in the future. The sales returns level can be impacted by factors such as overall market demand and market competition and availability for substitute products which can increase or decrease the pull through for sales of the Company’s products and ultimately impact the level of sales returns. For the three month period ended September 30, 2016, the Company incurred a return provision of $8.0 million , or 1.0% of gross sales of $787.8 million , compared to $7.7 million , or 1.2% of gross sales of $633.6 million in the prior year period. We note that the dollar increase and percentage decrease in the comparative period was the result of gross sale increases partially offset by product mix shifts to products with lower return rates. The Company ensures that this rate as a percentage of gross sales is reasonable through inspection of historical trends and evaluation of recent activity. Furthermore, other events that could materially alter return rates include: acquisitions and integration activities that consolidate dissimilar contract terms and could decrease the return rate as typically the Company purchases smaller entities with less contracting power and integrates those product sales to Akorn contracts; changes in demand driven by customer's acquisitions and integrations, loss of contract status, or consumer preference for available substitutes; and consumer demand shifts by products, which could either increase or decrease the return rate depending on the product or products specifically demanded and ultimately returned. To better understand the impact of changes in return reserve based on certain circumstances, the Company performs a sensitivity analysis. Holding all other assumptions constant, for an average 1.25 month change in the lag from the time of sale to the time the product return is processed, this change would result in an increase of $4.5 million or decrease of $6.1 million of the return reserve expense if the lag increases or decreases, respectively. The average 1.25 months change in the lag from the time of sale to the time the product return is processed was determined based on the average variances of the last 3-month historical activities. Due to the change in the volume and type of products sold by the Company in the recent past, we have determined that the lag calculation represents a reasonable basis for sensitivity analysis. Allowance for Coupons, Promotions and Co-Pay discount cards: The Company issues coupons from time to time that are redeemable against certain of our Consumer Health products. Upon release of coupons into the market, the Company records an estimate of the dollar value of coupons expected to be redeemed. This estimate is based on historical experience and is adjusted as needed based on actual redemptions. In addition to couponing, from time to time the Company authorizes various retailers to run in-store promotional sales of its products. Upon receiving confirmation that a promotion was run, the Company accrues an estimate of the dollar amount expected to be owed back to the retailer. This estimate is trued up to actual upon receipt of the invoice from the retailer. Additionally, the Company provides consumer co-pay discount cards, administered through outside agents to provide discounted products when redeemed. Upon release of the cards into the market, the Company records an estimate of the dollar value of co-pay discounts expected to be utilized. This estimate is based on historical experience and is adjusted as needed based on actual usage. Doubtful Accounts: Provisions for doubtful accounts, which reflect trade receivable balances owed to the Company that are believed to be uncollectible, are recorded as a component of selling, general and administrative ("SG&A") expenses. In estimating the allowance for doubtful accounts, the Company considers its historical experience with collections and write-offs, the credit quality of its customers and any recent or anticipated changes thereto, and the outstanding balances and past due amounts from its customers. Note that in the ordinary course of business, and consistent with our peers, we may from time to time offer extended payment terms to our customers as an incentive for new product launches and in other circumstances in accordance with industry practices. These extended payment terms do not represent a significant risk to the collectability of accounts receivable as of the period-end and are evaluated in accordance with Accounting Standards Codification ("ASC") 605 - Revenue Recognition as applicable. Accounts are considered past due when they remain uncollected beyond the due date specified in the applicable contract or on the applicable invoice, whichever is deemed to take precedence. Advertising and Promotional Allowances to Customers: The Company routinely sells its over-the-counter Consumer Health products to major retail drug chains. From time to time, the Company may arrange for these retailers to run in-store promotional sales of the Company’s products. The Company reserves an estimate of the dollar amount owed back to the retailer, recording this amount as a reduction to revenue at the later of the date on which the revenue is recognized or the date the sales incentive is offered. When the actual invoice for the sales promotion is received from the retailer, the Company adjusts its estimate accordingly. Advertising and promotional expenses paid to customers are expensed as incurred in accordance with ASC 605-50 - Customer Payments and Incentives . Inventories: Inventories are stated at the lower of cost (average cost method) or market. The Company maintains an allowance for slow-moving and obsolete inventory as well as inventory where the cost is in excess of its net realizable value. For finished goods inventory, the Company estimates the amount of inventory that may not be sold prior to its expiration or is slow moving based upon review of recent sales activity and wholesaler inventory information. The Company also analyzes its raw material and component inventory for slow moving items. The Company capitalizes inventory costs associated with its products prior to regulatory approval when, based on management judgment, future commercialization is considered probable and future economic benefit is expected to be realized. The Company assesses the regulatory approval process and where the product stands in relation to that approval process including any known constraints or impediments to approval. The Company also considers the shelf life of the product in relation to the product timeline for approval. Intangible Assets: Intangible assets consist primarily of goodwill and in-process research and development, which are carried at initial value and subject to evaluation for impairment, and product licensing costs, trademarks and other such costs, which are capitalized and amortized on a straight-line basis over their useful lives, ranging from one year to thirty years . The Company regularly assesses its intangible assets for impairment based on several factors, including estimated fair value and anticipated cash flows. If the Company incurs additional costs to renew or extend the life of an intangible asset, such costs are added to the remaining unamortized cost of the asset, if any, and the sum is amortized over the extended remaining life of the asset. Goodwill is tested for impairment annually or more frequently if changes in circumstances or the occurrence of events suggest that impairment may exist. The Company uses widely accepted valuation techniques to determine the fair value of its reporting units used in its annual goodwill impairment analysis. The Company’s valuation is primarily based on qualitative and quantitative assessments regarding the fair value of goodwill relative to its carrying value. The Company models the fair value of the reporting unit based on projected earnings and cash flows of the reporting unit. Property, Plant and Equipment: Property, plant and equipment is stated at cost, less accumulated depreciation. Depreciation is provided using the straight-line method in amounts considered sufficient to amortize the cost of the assets to depreciation expense over their estimated useful lives or capital lease terms. If applicable, the amortization of assets under capital leases is also included within depreciation expense. Net Income Per Common Share: Basic net income per common share is based upon the weighted average common shares outstanding. Diluted net income per common share is based upon the weighted average number of common shares outstanding, including the dilutive effect, if any, of stock options, restricted stock and convertible securities using the treasury stock and if converted methods. Anti-dilutive shares are excluded from the computation of diluted net income per share. Income Taxes: Income taxes are accounted for under the asset and liability method. Deferred income tax assets and liabilities are recognized for the tax effects of temporary differences between the financial reporting and tax bases of assets and liabilities, and net operating loss and other tax credit carry-forwards. These items are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The Company records a valuation allowance to reduce the recognized deferred tax assets to the amount that is more likely than not to be realized and classifies all deferred balances as non-current assets or liabilities by tax jurisdiction in the condensed consolidated balance sheet. Fair Value of Financial Instruments: The Company applies ASC 820 - Fair Value Measurement , which establishes a framework for measuring fair value and clarifies the definition of fair value within that framework. ASC 820 - Fair Value Measurement defines fair value as an exit price, which is the price that would be received for an asset or paid to transfer a liability in the Company’s principal or most advantageous market in an orderly transaction between market participants on the measurement date. The fair value hierarchy established in ASC 820 - Fair Value Measurement generally requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Observable inputs reflect the assumptions that market participants would use in pricing the asset or liability and are developed based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the entity’s own assumptions based on market data and the entity’s judgments about the assumptions that market participants would use in pricing the asset or liability, and are to be developed based on the best information available in the circumstances. The valuation hierarchy is composed of three levels. The classification within the valuation hierarchy is based on the lowest level of input that is significant to the fair value measurement. The levels within the valuation hierarchy are described below: - Level 1 —Assets and liabilities with unadjusted, quoted prices listed on active market exchanges. Inputs to the fair value measurement are observable inputs, such as quoted prices in active markets for identical assets or liabilities. The carrying value of the Company‘s cash and cash equivalents and the portion of the value of the Nicox S.A. ("Nicox") shares which are available to be traded on the exchange are considered Level 1 assets. - Level 2 —Inputs to the fair value measurement are determined using prices for recently traded assets and liabilities with similar underlying terms, as well as directly or indirectly observable inputs, such as interest rates and yield curves that are observable at commonly quoted intervals. The Company has no Level 2 assets or liabilities in any of the periods presented. - Level 3 —Inputs to the fair value measurement are unobservable inputs, such as estimates, assumptions, and valuation techniques when little or no market data exists for the assets or liabilities. The portion of the fair valuation of the available-for-sale investment held in shares of Nicox subject to a lock-up provision is considered a Level 3 asset. The additional consideration payable as a result of prior years divestitures and other insignificant contingent amounts are considered Level 3 liabilities. The following table summarizes the basis used to measure the fair values of the Company’s financial instruments (amounts in thousands): Fair Value Measurements at Reporting Date, Using: Description September 30, 2016 Quoted Prices in Active Markets for Identical Items (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Cash and cash equivalents $ 174,050 $ 174,050 $ — $ — Available-for-sale securities 1,143 1,107 — 36 Total assets $ 175,193 $ 175,157 $ — $ 36 Purchase consideration payable $ 4,987 $ — $ — $ 4,987 Total liabilities $ 4,987 $ — $ — $ 4,987 Description December 31, 2015 Quoted Prices in Active Markets for Identical Items (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Cash and cash equivalents $ 346,266 $ 346,266 $ — $ — Available-for-sale securities 5,941 4,843 — 1,098 Total assets $ 352,207 $ 351,109 $ — $ 1,098 Purchase consideration payable $ 4,967 $ — $ — $ 4,967 Total liabilities $ 4,967 $ — $ — $ 4,967 As of September 30, 2016 , the Company was carrying available-for-sale investments in shares of Nicox. These shares of Nicox were initially valued at $12.5 million discounted to reflect certain lockup provisions preventing immediate conversion of underlying shares received for the Company’s investment in an available-for-sale security, or an $1.7 million unrealized gain from the original costs basis of $10.8 million . During the years ended December 31, 2015 and 2014 the Company sold $2.6 million and $ 0.6 million , respectively of the available-for-sale securities. During the three and nine months ended September 30, 2016 the Company sold $0 and $6.0 million , respectively of the available-for-sale securities, realizing an immaterial loss through the sales and recognized a $0.4 million unrealized loss of the remaining investment as of September 30, 2016 . The remaining $1.1 million of securities are subject to certain lockup provisions and as such, the fair value of the investment is estimated using observable and unobservable inputs to discount for lack of marketability. The remaining purchase consideration payable is principally comprised of amounts owed relating to various prior years divestitures, at fair value as determined based on the underlying contracts and the Company’s subjective evaluation of the additional consideration obligation estimate. Stock-Based Compensation: Stock-based compensation cost is estimated at grant date based on the fair value of the award, and the cost is recognized as expense ratably over the vesting period. The Company uses the Black-Scholes model for estimating the grant date fair value of stock options. Determining the assumptions to be used in the model is highly subjective and requires judgment. The Company uses an expected volatility that is based on the historical volatility of its common stock. The expected life assumption is based on historical employee exercise patterns and employee post-vesting termination behavior. The risk-free interest rate for the expected term of the option is based on the average market rate on U.S. Treasury securities of similar term in effect during the quarter in which the options were granted. The dividend yield reflects the Company’s historical experience as well as future expectations over the expected term of the option. The Company estimates forfeitures at the time of grant and revises the estimate in subsequent periods, as necessary, if actual forfeitures differ from initial estimates. Business Combinations: Business combinations are accounted for in accordance with ASC 805 - Business Combinations , using the acquisition method of accounting. The acquisition method of accounting 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 co |
