Revenue Recognition. The Company performs the following five steps in determining the amount of revenue to recognize as it fulfills its performance obligations under each of its agreements: (a) identify the contract(s) with a customer; (b) identify the performance obligations in the contract; (c) determine the transaction price; (d) allocate the transaction price to the performance obligations in the contract, and (e) recognize revenue when (or as) the Company satisfies the performance obligation. The Company applies this five-step model to contracts when it is probable that the Company will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. At contract inception, the Company assesses the goods or services promised within each contract and determines those that are performance obligations, and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. The Company develops assumptions that require judgment to determine the stand-alone selling price for each performance obligation identified in the contract.
Product Revenues
Product revenues consist of U.S. sales of INPEFA, which Lexicon began shipping to its customers in the U.S. in June 2023. These customers primarily include wholesalers and limited retail pharmacies. The Company is continuing to contract with certain managed care programs or pharmacy benefit managers (“PBMs”) and has legislatively mandated contracts with the federal and state governments under which rebates are provided based on product utilization. Product revenues are recognized when control is transferred to the customer upon delivery.
The Company recognizes product revenue net of applicable estimates of reserves for variable consideration using the expected value method. These estimates consider relevant factors such as current contractual and statutory requirements, industry data and forecasted customer buying and payment patterns. Net product revenue includes variable consideration only to the extent that it is probable that a significant reversal in revenue recognized will not occur in a future period. As necessary, these estimates will be adjusted in the period that such variances to actuals become known. Listed below is a further discussion of these reserves and sales return allowances:
Customer Credits. The Company’s customers are offered various forms of consideration, including allowances, service fees and prompt payment discounts. The Company records allowances, deducts the full amount of prompt payment discounts, and deducts service fees from total product sales when revenues are earned and recognized.
Rebates. Allowances for rebates include mandated discounts under the Medicaid Drug Rebate Program reflecting amounts owed after final dispensing of the product to participants. The Company’s estimates for rebates is based on statutory discount rates, third party market research data and data from sales to its customers. As rebates are generally invoiced and paid in arrears, the Company accrues an estimate of rebates based on the current quarter’s activity, plus any known unpaid prior quarter rebates.
Chargebacks. Chargebacks are discounts that occur when contracted healthcare providers purchase directly from a wholesaler. Generally, the contracted healthcare providers purchase INPEFA at a discounted price. The wholesaler, in turn, charges back to Lexicon the difference between the price paid by the wholesaler and the discounted price that the wholesaler’s customer pays for that product.
Medicare Part D Coverage Gap. The Medicare Part D prescription drug benefit mandates manufacturers to fund a portion of the Medicare Part D insurance coverage gap for prescription drugs sold to eligible patients. The Company’s estimates for the expected Medicare Part D coverage gap are based on sales data received from a third party and projections based on historical data. As funding of the coverage gap is generally invoiced and paid in arrears, the Company accrues an estimate based on the current quarter’s activity, plus any known unpaid prior quarter estimates.
Co-payment assistance. Patients with commercial insurance who meet certain eligibility requirements are eligible to receive co-payment assistance. The Company accrues a liability for co-payment assistance based on actual program participation and estimates of program redemption using data provided by third-party administrators.
Sales returns. The Company records allowances for product returns, if appropriate, as a reduction of revenue at the time product sales are recorded based on an assessment of market exclusivity of the product, the patient population and the customers’ return rights.
