Significant accounting policies

In June 2016, the Financial Accounting Standards Board, or FASB issued Accounting Standards Update, or ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), which introduces new guidance for the accounting for credit losses on instruments within its scope. The new guidance introduces an approach based on expected losses to estimate credit losses on certain types of financial instruments. Credit losses relating to available-for-sale debt securities will also be recorded through an allowance for credit losses rather than as a reduction in the amortized cost basis of the securities. The guidance is effective for fiscal years beginning after December 31, 2019, including interim periods within those years.

In the quarter ended March 31, 2020, we adopted ASU 2016-13, which eliminated the concept of other-than-temporary impairments and required credit losses on debt securities to be recorded through an allowance for credit losses instead of as a reduction in the amortized cost basis of the securities. Application of the amendments is through a cumulative-effect adjustment to retained earnings as of the effective date. Based upon our analysis, the adoption of this final rule did not have a material impact on the financial statements.

Liability related to sale of future revenue

We treat the sale of future revenue to RPI as a debt financing, as we have significant continuing involvement in the generation of the cash flows. As result, we recorded the proceeds from this transaction as a liability related to the sale of future revenue to be amortized to interest expense using the effective interest rate method over the life of the arrangement.

The liability related to sale of future revenue and the related interest expense are based on our current estimates of future royalties expected to be paid over the life of the arrangement. We will periodically assess the expected royalty payments using a combination of internal projections and forecasts from external sources. To the extent our future estimates of royalty payments are greater or less than previous estimates or the estimated timing of such payments is materially different than its previous estimates, we will prospectively recognize related non-cash interest expense.

For further discussion of the sale of future revenue, refer to Note 10, Sale of Future Revenue.

Amortization of issuance costs

We treated the liability related to sale of future revenue as a debt financing. As such, the long-term liability is initially recorded at its proceeds, net of deferred costs. Issuance costs, fees directly related to the sale of future revenue, are offset against initial carrying value of the long-term liability and are amortized on a straight-line basis over the remaining patent life of the product to an operating expense.

There have been no other material changes to the significant accounting policies previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2019.

Recent accounting pronouncements

Other accounting standards that have been issued by the FASB or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on our financial statements upon adoption.
