Investments | Investments Fixed Maturity Securities We evaluate our available-for-sale fixed maturity securities for other-than-temporary declines based on qualitative and quantitative factors. There were no individually significant other-than-temporary impairment losses on investments during the three and nine months ended September 30, 2018 and 2017. We continue to review our investment portfolios under our impairment review policy. Given the inherent uncertainty of changes in market conditions and the significant judgments involved, there is a continuing risk that further declines in fair value may occur and additional material other-than-temporary impairment losses on investments may be recorded in future periods. A summary of current and long-term fixed maturity securities, available-for-sale, at September 30, 2018 and December 31, 2017 is as follows:
For fixed maturity securities in an unrealized loss position at September 30, 2018 and December 31, 2017, the following table summarizes the aggregate fair values and gross unrealized losses by length of time those securities have continuously been in an unrealized loss position:
The amortized cost and fair value of fixed maturity securities at September 30, 2018, by contractual maturity, are shown below. Expected maturities may differ from contractual maturities because the issuers of the securities may have the right to prepay obligations.
Proceeds from sales, maturities, calls or redemptions of fixed maturity securities and the related gross realized gains and gross realized losses for the three and nine months ended September 30, 2018 and 2017 are as follows:
In the ordinary course of business, we may sell securities at a loss for a number of reasons, including, but not limited to: (i) changes in the investment environment; (ii) expectation that the fair value could deteriorate further; (iii) desire to reduce exposure to an issuer or an industry; (iv) changes in credit quality; or (v) changes in expected cash flow. All securities sold resulting in investment gains and losses are recorded on the trade date. Realized gains and losses are determined on the basis of the cost or amortized cost of the specific securities sold. Equity Securities A summary of current and long-term equity securities at September 30, 2018 and December 31, 2017 is as follows:
The gains and losses related to equity securities for the three and nine months ended September 30, 2018 are as follows:
The gross realized gains recognized on sales of equity securities for the three and nine months ended September 30, 2017 were $96 and $120, respectively. The gross realized losses recognized on sales of equity securities for the three and nine months ended September 30, 2017 were $8 and $13, respectively. Securities Lending Programs We participate in securities lending programs whereby marketable securities in our investment portfolio are transferred to independent brokers or dealers in exchange for cash and securities collateral. The fair value of the collateral received at the time of the transactions amounted to $741 and $454 at September 30, 2018 and December 31, 2017, respectively. The value of the collateral represented 103% and 104% of the market value of the securities on loan at September 30, 2018 and December 31, 2017, respectively. We recognize the collateral as an asset under the caption “Securities lending collateral” on our consolidated balance sheets and we recognize a corresponding liability for the obligation to return the collateral to the borrower under the caption “Securities lending payable.” The securities on loan are reported in the applicable investment category on our consolidated balance sheets. The remaining contractual maturity of our securities lending agreements at September 30, 2018 is as follows:
The market value of loaned securities and that of the collateral pledged can fluctuate in non-synchronized fashions. To the extent the loaned securities' value appreciates faster or depreciates slower than the value of the collateral pledged, we are exposed to the risk of the shortfall. As a primary mitigating mechanism, the loaned securities and collateral pledged are marked to market on a daily basis and the shortfall, if any, is collected accordingly. Secondarily, the minimum collateral level is set at 102% of the value of the loaned securities, which provides a cushion before any shortfall arises. The investment of the cash collateral is subject to market risk, which is managed by limiting the investments to higher quality and shorter duration instruments. |
