Revenue Recognition | Note 4. Revenue Recognition ​ Product revenues, net ​ In accordance with ASC 606 Revenue from Contracts with Customers, revenue is recognized at the time that the Company’s customers obtain control of the promised goods. ​ Generally, revenue is recognized at the time of product delivery to the Company’s customers. In some cases, revenue is recognized at the time of shipment when stipulated by the terms of the sale agreements. ​ The consideration the Company receives in exchange for its goods or services is only recognized when it is probable that a significant reversal will not occur. The consideration to which the Company expects to be entitled includes a stated list price, less various forms of variable consideration. The Company makes significant estimates for related variable consideration at the point of sale, including chargebacks, rebates, product returns, other discounts and allowances. ​ The Company’s payment terms vary by types and locations of customers and the products or services offered. Payment terms differ by jurisdiction and customers, but payment is generally required in a term ranging from 30 to 75 days from date of shipment or satisfaction of the performance obligation. For certain products or services and certain customer types, the Company may require payment before products are delivered or services are rendered to customers. ​ Provisions for estimated chargebacks, rebates, discounts, product returns and credit losses are made at the time of sale and are analyzed and adjusted, if necessary, at each balance sheet date. ​ Revenues derived from contract manufacturing services are recognized when third-party products are shipped to customers. ​ The Company’s accounting policy is to review each agreement involving contract development and manufacturing services to determine if there are multiple revenue-generating activities that constitute more than one unit of accounting. Revenues are recognized for each unit of accounting based on revenue recognition criteria relevant to that unit. The Company does not have any revenue arrangements with multiple performance obligations. ​ Service revenues derived from research and development contracts are recognized over time based on progress toward satisfaction of the performance obligation. For each performance obligation satisfied over time, the Company assesses the proper method to be used for revenue recognition, either an input method to measure progress toward the satisfaction of services or an output method of determining the progress of completion of performance obligation. For the three and nine months ended September 30, 2023, revenues from research and development services at ANP were $0.8 million and $2.1 million, respectively. For the three and nine months ended September 30, 2022, revenues from research and development services at ANP were $0.8 million and $2.1 million, respectively. ​ Other revenues ​ Revenues related to sales of BAQSIMI®, which was acquired on June 30, 2023 and was manufactured and sold by Lilly under the TSA during the three months ended September 30, 2023, were recorded on a net basis, similar to a royalty arrangement. ​ 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 as a component of net revenues. The following table is an analysis of the chargeback and rebate provision: ​

Beginning balance |  | $ | 26,606 |  | $ | 20,167
Provision for chargebacks and rebates | ​ |  | 200,317 | ​ |  | 147,899
Credits and payments issued to third parties | ​ |  | (201,650) | ​ |  | (144,233)
Ending balance | ​ | $ | 25,273 | ​ | $ | 23,833
​ Changes in the provision for chargebacks from period to period are primarily dependent on the Company’s sales to its wholesalers, the level of inventory held by wholesalers, and the wholesalers’ customer mix. Changes in the provision for rebates 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 20 days to 60 days after the sale to wholesalers. The provision for chargebacks and rebates is recorded within accounts receivable and/or accounts payable and accrued liabilities depending on whether the Company has the right to offset with the customer. ​ Of the provision for chargebacks and rebates as of September 30, 2023 and December 31, 2022, $18.9 million and $20.5 million were included as a reduction to accounts receivable, net, on the condensed consolidated balance sheets, respectively. The remaining provision as of September 30, 2023 and December 31, 2022 of $6.4 million and $6.1 million, respectively, which were included in accounts payable and accrued liabilities in the condensed consolidated balance sheets. ​ 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 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. ​ ​ The provision for product returns is reflected as a component of net revenues. The following table is an analysis of the product return liability: ​
​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Nine Months Ended
​ | ​ | September 30,
​ | ​ | 2023 | ​ | 2022
​ | ​ | (in thousands)
Beginning balance |  | $ | 19,451 |  | $ | 21,677
Provision for product returns | ​ |  | 2,750 | ​ |  | 3,086
Credits issued to third parties | ​ |  | (4,467) | ​ |  | (5,019)
Ending balance | ​ | $ | 17,734 | ​ | $ | 19,744
​ Of the provision for product returns as of September 30, 2023 and December 31, 2022, $12.9 million and $14.9 million, were included in accounts payable and accrued liabilities on the condensed consolidated balance sheets, respectively. The remaining provision as of September 30, 2023 and December 31, 2022 of $4.8 million and $4.6 million, were included in other long-term liabilities, respectively. For the nine months ended September 30, 2023 and 2022, the Company’s aggregate product return rate was 1.1% and 1.4% of qualified sales, respectively.
