When assessing our intent to sell a debt security, or if it is more likely than not we will be required to sell a debt security before recovery of its cost basis, we evaluate facts and circumstances such as, but not limited to, decisions to reposition our security portfolio, sales of securities to meet cash flow needs and sales of securities to capitalize on favorable pricing. Management considers the following as part of the evaluation:
We further monitor the cash flows of all of our fixed maturity AFS securities backed by mortgages on an ongoing basis. We also perform detailed analysis on all of our subprime, Alt-A, non-agency residential MBS and on a significant percentage of our fixed maturity AFS securities backed by pools of commercial mortgages. The detailed analysis includes revising projected cash flows by updating the cash flows for actual cash received and applying assumptions with respect to expected defaults, foreclosures and recoveries in the future. These revised projected cash flows are then compared to the amount of credit enhancement (subordination) in the structure to determine whether the amortized cost of the security is recoverable. If it is not recoverable, we record an impairment of the security.
ASU 2018-12, Targeted Improvements to the Accounting for Long-Duration Contracts and related amendments
As of December 31, 2019, the unrealized losses associated with our hybrid and redeemable preferred securities were attributable primarily to wider credit spreads caused by illiquidity in the market and subordination within the capital structure, as well as credit risk of underlying issuers. For our hybrid and redeemable preferred securities, we evaluated the financial performance of the underlying issuers based upon credit performance and investment ratings and determined that we expected to recover the entire amortized cost of each temporarily-impaired security.
Failure of the issuer of the security to make scheduled payments;
We recognize the OTTI attributed to the noncredit portion as a separate component in OCI referred to as unrealized OTTI on fixed maturity AFS securities.
The weighted average discount rate was determined based on a corporate yield curve as of December 31, 2019, and projected benefit obligation cash flows. The expected return on plan assets was determined based on historical and expected future returns of the various asset categories, using the plans’ target plan allocation. We reevaluate these assumptions each plan year.
(8)The mortality rate is based on a combination of company and industry experience, adjusted for improvement factors.
We provide products and services and report results through our Annuities, Retirement Plan Services, Life Insurance and Group Protection segments. As discussed in Note 3, we completed the acquisition of Liberty Life during the second quarter of 2018. Related results are included within the Group Protection segment. We also have Other Operations, which includes the financial data for operations that are not directly related to the business segments. Our reporting segments reflect the manner by which our chief operating decision makers view and manage the business. The following is a brief description of these segments and Other Operations.
