Impairment. During the three and six months ended June 30, 2020, we recorded impairment losses in earnings of $3.6 million and $4.2 million, respectively. See below for additional details on our net gains (losses) on investments and Note 1 for a discussion of our accounting policy for impairments, including our adoption of ASU 2016-13 effective January 2020. We did not have the intent to sell any additional available for sale debt securities in an unrealized loss position, and we determined that it is more likely than not that we will not be required to sell the securities before recovery of their cost basis, which may be at maturity. Securities Lending Agreements We participate in a securities lending program whereby we loan certain securities in our investment portfolio to third-party borrowers for short periods of time. Although we report such securities at fair value within other assets in our condensed consolidated balance sheets, rather than within investments, the detailed information we provide in this Note 5 includes these securities. See Note 4 for additional detail on the loaned securities, and see Notes 2 and 6 of Notes to Consolidated Financial Statements in our 2019 Form 10-K for additional information about our accounting policies with respect to our securities lending agreements and the collateral requirements thereunder, respectively. All of our securities lending agreements are classified as overnight and revolving. Securities collateral on deposit with us from third-party borrowers totaling $7.8 million and $42.4 million as of June 30, 2020 and December 31, 2019, respectively, may not be transferred or re-pledged unless the third-party borrower is in default, and is therefore not reflected in our condensed consolidated financial statements.
