Contract Assets and Liabilities

We receive payments from our collaboration partners based on billing schedules established in each contract. Amounts are recorded as accounts receivable when our right to consideration is unconditional. We may also recognize revenue in advance of the contractual billing schedule and such amounts are recorded, net of any allowance for credit losses, as a contract asset when recognized. Contract assets, which are presented in prepaid expenses and other current assets in the accompanying Condensed Consolidated Balance Sheets, were $0 and $1.1 million as of March 31, 2020 and December 31, 2019, respectively. We may be required to defer recognition of revenue for upfront and milestone payments until we perform our obligations under these arrangements, and such amounts are recorded as deferred revenue upon receipt or when due. Contract liabilities were $15.4 million and $6.6 million as of March 31, 2020 and December 31, 2019, respectively. The current portion of the contract liabilities, which are presented in other current liabilities in the accompanying Condensed Consolidated Balance Sheets, were $1.3 million and $0 as of March 31, 2020 and December 31, 2019, respectively. The remainder of the contract liabilities are presented in long-term portion of deferred revenue in the accompanying Condensed Consolidated Balance Sheets. For those contracts that have multiple performance obligations, contract assets and liabilities are reported on a net basis at the contract level.

Significant changes in contract assets during the three months ended March 31, 2020, as compared to December 31, 2019, include the impact of a $10.0 million milestone from Takeda Pharmaceutical Company Limited (Takeda) which was achieved, invoiced and collected during the period.

During the three months ended March 31, 2020 and 2019, we recognized $1.6 million and $1.3 million, respectively, in revenues that were included in the beginning deferred revenue balance for those years.

During the three months ended March 31, 2020 and 2019, we recognized $18.8 million and $25.3 million, respectively, in revenues for performance obligations satisfied in previous periods. Such revenues primarily related to

milestone and royalty payments allocated to our license performance obligations of our collaborations with Ipsen, Takeda and Daiichi Sankyo.

As of March 31, 2020, $65.1 million of the transaction price was allocated to performance obligations that had not yet been satisfied, which was considered in the determination of contract assets and liabilities. See “Note 3. Collaboration Agreements - Cabozantinib Commercial Collaborations - Performance Obligations and Transaction Prices for our Ipsen and Takeda Collaborations” to our Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2019 for information about the expected timing to satisfy these performance obligations.
