Impairments due to credit deterioration that result in a conclusion that the present value of cash flows expected to be collected will not be sufficient to recover the amortized cost basis of the security are considered other-than-temporary. Other declines in fair value (for example, due to interest rate changes, sector credit rating changes or company-specific rating changes) that result in a conclusion that the present value of cash flows expected to be collected will not be sufficient to recover the amortized cost basis of the security also may serve as a basis to conclude that an other-than-temporary impairment has occurred. To the extent we determine that a security is deemed to have had an other-than-temporary impairment, an impairment loss is recognized. During the three months ended March 31, 2018, we recorded other-than-temporary impairment losses in earnings of $0.9 million due to our intent to sell certain corporate and state and municipal bonds at a loss. For the year ended December 31, 2017, we recorded other-than-temporary impairment losses in earnings of $1.4 million. These losses comprised $0.4 million recorded due to our intent to sell certain corporate bonds at a loss and $1.0 million recorded due to credit deterioration, which included $0.5 million related to a convertible note of a non-public company issuer included in debt securities and $0.5 million related to a privately-placed equity security. There were no credit-related impairment losses recognized in accumulated other comprehensive income (loss) during the three months ended March 31, 2018 or year ended December 31, 2017. Although we held securities in an unrealized loss position as of March 31, 2018, we did not consider those securities to be other-than-temporarily impaired as of such date. For all investment categories, the unrealized losses of 12 months or greater duration as of March 31, 2018 were generally caused by interest rate or credit spread movements since the purchase date, and as such, we expect the present value of cash flows to be collected from these securities to be sufficient to recover the amortized cost basis of these securities. As of March 31, 2018, we did not have the intent to sell any 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; therefore, we did not consider these investments to be other-than-temporarily impaired at March 31, 2018. Trading Securities The trading securities within our investment portfolio, which are recorded at fair value, consisted of the following as of the dates indicated:

______________________
(1) | Includes a de minimis amount of loaned securities under securities lending agreements that are classified as other assets in our consolidated balance sheets, as further described below.
For trading securities held at March 31, 2018, we had net unrealized losses associated with those securities of $11.4 million during the three months ended March 31, 2018, compared to net unrealized gains of $3.5 million for the three months ended March 31, 2017. For equity securities held at March 31, 2018, we had net losses of $1.8 million during the three months ended March 31, 2018. Prior to the implementation of the update to the standard for the accounting of financial instruments effective January 1, 2018, the unrealized losses associated with equity securities were classified in accumulated other comprehensive income. For the three months ended March 31, 2018, we did not transfer any securities from the available for sale or trading categories. Securities Lending Agreements During the third quarter of 2017, we commenced participation in a securities lending program whereby we loan certain securities in our investment portfolio to Borrowers for short periods of time. These securities lending agreements are collateralized financing arrangements whereby we transfer securities to third parties through an intermediary in exchange for cash or other securities. In all of our securities lending agreements, the securities we transfer to Borrowers (loaned securities) may be transferred or loaned by the Borrowers; however, we maintain effective control over all loaned securities, including: (i) retaining ownership of the securities; (ii) receiving the related investment or other income; and (iii) having the right to request the return of the loaned securities at any time. Although we report such securities at fair value within other assets in our condensed consolidated balance sheets, the detailed information regarding investments provided in this Note includes these securities. Under our securities lending agreements, the Borrower is required to provide to us collateral, consisting of cash or securities, in amounts generally equal to or exceeding (i) 102% of the value of the loaned securities (105% in the case of foreign securities) or (ii) another agreed-upon percentage not less than 100% of the market value of the loaned securities. Any cash collateral we receive may be invested in liquid assets. The Borrower generally may return the loaned securities to us at any time, which would require us to return the collateral within the standard settlement period for the loaned securities on the principal exchange or market in which the securities are traded. We manage this liquidity risk associated with cash collateral by maintaining the cash collateral in a short-term money-market fund with daily availability. The credit risk under these programs is reduced by the amounts of collateral received. On a daily basis, the value of the underlying securities that we have loaned to the Borrowers is compared to the value of cash and securities collateral we received from the Borrowers, and additional cash or securities are requested or returned, as applicable. In addition, we are indemnified against counterparty credit risk by the intermediary. Key components of our securities lending agreements at March 31, 2018 and December 31, 2017 consisted of the following:
(In thousands) | March 31, 2018 |  | December 31, 2017

(2) | Securities collateral on deposit with us from Borrowers may not be transferred or re-pledged unless the Borrower is in default, and is therefore not reflected in our condensed consolidated financial statements.
(3) | All cash collateral received has been reinvested in accordance with the securities lending agreements and is included in short-term investments in our condensed consolidated balance sheets. Amounts payable on the return of cash collateral under securities lending agreements are included within other liabilities in our condensed consolidated balance sheets.

For the three months ended March 31, 2017, the amount excludes the net change in unrealized gains and losses on equity securities. Prior to the implementation of the update to the standard for the accounting of financial instruments effective January 1, 2018, the unrealized losses associated with equity securities were classified in accumulated other comprehensive income.
