As of June 30, 2020 and December 31, 2019, fixed maturity securities comprised approximately 84% and 83%, respectively, of the Company’s total investments. Rating agency designations are based on the availability of ratings from Nationally Recognized Statistical Rating Organizations (“NRSROs”), including Moody’s Investors Service (“Moody’s”), Standard & Poor’s Ratings Services (“S&P”) and Fitch Ratings Ltd. (“Fitch”). The Company uses the median of available ratings from Moody’s, S&P and Fitch, or if fewer than three ratings are available, the lower rating is used. When ratings from Moody’s, S&P and Fitch are unavailable, the Company may utilize ratings from other NRSROs or rate the securities internally. As of June 30, 2020 and December 31, 2019, approximately $607 million and $615 million, respectively, of securities were internally rated by Columbia Management Investment Advisers, LLC, an affiliate of the Company, using criteria similar to those used by NRSROs.

As part of the Company’s ongoing monitoring process, management determined that the change in gross unrealized losses on its Available-for-Sale securities during the six months ended June 30, 2020 is attributable to wider credit spreads, partially offset by lower interest rates. Consistent with the accounting policy described in Note 2, the Company did not recognize these unrealized losses in earnings because it was determined that such losses were due to non-credit factors. The Company does not intend to sell these

securities and does not believe that it is more likely than not that the Company will be required to sell these securities before the anticipated recovery of the remaining amortized cost basis. As of June 30, 2020, 64% of the total of Available-for-Sale securities with gross unrealized losses were considered investment grade.

⁽¹⁾ Prior to January 1, 2020, credit losses on Available-for-Sale securities were not recorded in an allowance but were recorded as a reduction of the book value of the security if the security was other-than-temporarily impaired. There is no adoption impact due to the prospective transition for Available-for-Sale securities.

Residential mortgage backed securities, commercial mortgage backed securities and asset backed securities are not due at a single maturity date. As such, these securities were not included in the maturities distribution.
