In each category of our fixed maturity securities described below, we do not intend to sell our investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost bases. While the losses are currently unrealized, we continue to monitor all fixed maturity securities on an on-going basis as future information may become available which could result in an allowance being recorded.

States and political subdivisions. The Company's investments in states and political subdivisions were purchased at a premium, relative to their face amount, and the contractual cash flows are guaranteed by the respective state or political subdivision. Accordingly, it is expected that the securities will not be settled at a price less than the amortized cost bases of the Company's investments.

Corporate. We did not recognize credit losses on corporate securities with unrealized losses that were due to interest rate sensitivity and changes in credit spreads. We believe that fluctuations caused by movements in interest rates and credit spreads have little bearing on the recoverability of our investments. While we are experiencing unrealized losses across several corporate sectors, the energy and automobile sectors have been impacted the most by recent economic pressures and some issuers within these sectors have been downgraded to below investment grade. We have assessed our exposure in the energy sector and believe our investments have access to sufficient liquidity to meet their debt obligations. The auto industry has been able to issue debt which has increased the liquidity of the component companies in the sector significantly. The automobile sector is included in the Consumer subtotal above.

Asset-backed. Our asset-backed securities are primarily collateralized loan obligations. We do not expect to realize any losses for these securities and see the current valuations as a result of general market conditions. All of the active asset-backed securities are rated investment grade.

The following table presents the fair values and gross unrealized losses of fixed maturity securities that are not deemed to have OTTI, aggregated by investment category and length of time that individual securities have been in a continuous loss position at December 31, 2019.
