Revenue from Contract with Customer [Abstract]

REVENUE

REVENUE

Revenue from Contracts with Customers

The Company’s net product sales consist of (i) EXPAREL in the U.S., the European Union, or E.U., and the U.K.; (ii) ZILRETTA in the U.S.; (iii) iovera° in the U.S., Canada and the E.U. and (iv) sales of, and royalties on, its bupivacaine liposome injectable suspension for veterinary use. Royalty revenues are from the Company’s collaborative licensing agreements. The Company does not consider revenue from sources other than sales of EXPAREL and ZILRETTA to be material sources of its consolidated revenue. As such, the following disclosure only relates to revenue associated with net EXPAREL and ZILRETTA product sales.

Net Product Sales

The Company sells EXPAREL through a drop-ship program under which orders are processed through wholesalers based on orders of the product placed by end-users, namely hospitals, ambulatory surgery centers and healthcare provider offices. EXPAREL is delivered directly to the end-user without the wholesaler ever taking physical possession of the product. The Company primarily sells ZILRETTA to specialty distributors and a specialty pharmacy, who then subsequently resell ZILRETTA to physicians, clinics and certain medical centers or hospitals. The Company also contracts directly with healthcare providers and intermediaries such as GPOs. Product revenue is recognized when control of the promised goods are transferred to the customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for transferring those goods. EXPAREL and ZILRETTA revenue is recorded at the time the product is transferred to the customer.

Revenues from sales of products are recorded net of returns allowances, prompt payment discounts, service fees, government rebates, volume rebates and chargebacks. These reserves are based on estimates of the amounts earned or to be claimed on the related sales. These amounts are treated as variable consideration, estimated and recognized as a reduction of the transaction price at the time of the sale, using the most likely amount method, except for returns, which is based on the expected value method. The Company includes these estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized for such transaction will not occur, or when the uncertainty associated with the variable consideration is resolved. The calculation of some of these items requires management to make estimates based on sales data, historical return data, contracts, statutory requirements and other related information that may become known in the future.

Accounts Receivable

The majority of accounts receivable arise from product sales and represent amounts due from wholesalers, hospitals, ambulatory surgery centers, specialty distributors, specialty pharmacy, GPOs and doctors. Payment terms generally range from zero to 97 days from the date of the transaction, and accordingly, there is no significant financing component.

Performance Obligations

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account in Accounting Standards Codification, or ASC, 606. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied.

At contract inception, the Company assesses the goods promised in its contracts with customers and identifies a performance obligation for each promise to transfer to the customer a good that is distinct. When identifying individual performance obligations, the Company considers all goods promised in the contract regardless of whether explicitly stated in the customer contract or implied by customary business practices. The Company’s contracts with customers require it to transfer an individual distinct product, which represents a single performance obligation. The Company’s performance obligation with respect to its product sales is satisfied at a point in time, which transfers control upon delivery of EXPAREL and ZILRETTA to its customers. The Company considers control to have transferred upon delivery because the customer has legal title to the asset, physical possession of the asset has been transferred, the customer has significant risks and rewards of ownership of the asset, and the Company has a present right to payment at that time.
