(1)Durations shown represent our estimates as of the current reporting date of when a royalty will substantially end, which may vary by geography and may depend on clinical trial results, regulatory approvals, contractual terms, commercial developments, estimates of regulatory exclusivity and patent expiration dates (which may include estimated patent term extensions) or other factors. There can be no assurances that our royalties will expire when expected.

(2)Royalty is perpetual. We estimate royalty duration of 2039-2041 due to expected Alyftrek patent expiration and potential generic entry thereafter leading to sales decline.

(3)Royalty is perpetual. We have applied an end date of 2035 for purposes of accreting income over the royalty term, which is periodically reviewed based on our estimates of impact from biosimilars.

(4)The net carrying value by asset is presented before the allowance for credit losses. Refer to Note 9–Cumulative Allowance and the Provision for Changes in Expected Cash Flows from Financial Royalty Assets for additional information.
