Maturities

The amortized cost and fair value of held-to-maturity, available-for-sale and trading fixed maturity securities at December 31, 2018, by contractual maturity, are shown in the following table. Actual maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. Asset-backed securities, mortgage-backed securities and collateralized mortgage obligations may be subject to prepayment risk and are therefore not categorized by contractual maturity.

Our investment portfolio includes trading securities with embedded derivatives. These securities are primarily convertible securities which are recorded at fair value. Income or loss, including the change in the fair value of these trading securities, is recognized currently in earnings as a component of net realized investment gains and losses. Our portfolio of trading securities had a fair value of $13,240 and $16,842 at December 31, 2018 and 2017, respectively.

We continually monitor the difference between our cost basis and the estimated fair value of our investments. Our accounting policy for impairment recognition requires other-than-temporary impairment ("OTTI") charges to be recorded when we determine that it is more likely than not that we will be unable to collect all amounts due according to the contractual terms of the fixed maturity security. Impairment charges on investments are recorded based on the fair value of the investments at the measurement date or based on the value calculated using a discounted cash flow model. Credit-related impairments on fixed maturity securities that we do not plan to sell, and for which we are not more likely than not to be required to sell, are recognized in net income. Any non-credit related impairment is recognized as a component of other comprehensive income. Factors considered in evaluating whether a decline in value is other-than-temporary include: the length of time and the extent to which fair value has been less than cost; the financial condition and near-term prospects of the issuer; our intention to hold the investment; and the likelihood that we will be required to sell the investment.

The tables on the following pages summarize our fixed maturity and equity securities that were in an unrealized loss position at December 31, 2018 and 2017 for continuing operations and discontinued operations. The securities are presented by the length of time they have been continuously in an unrealized loss position. It is possible that we could recognize OTTI charges in future periods on securities held at December 31, 2018 if future events or information cause us to determine that a decline in fair value is other-than-temporary.

We have evaluated the near-term prospects of the issuers of our fixed maturity securities in relation to the severity and duration of the unrealized loss and determined that these losses did not warrant the recognition of an OTTI charge in 2018, 2017 or 2016. All fixed maturity securities in the investment portfolio continue to pay the expected coupon payments under the contractual terms of the securities. We believe the unrealized depreciation in value of other securities in our fixed maturity portfolio is primarily attributable to changes in market interest rates and not the credit quality of the issuer. We have no intention to sell and it is more likely than not that we will not be required to sell these securities until the fair value recovers to at least equal to our cost basis or the securities mature.
