Portfolio composition by investment strategy We utilize two primary strategies to manage risks and returns and to position our portfolio to take advantage of market opportunities while attempting to mitigate adverse effects. As strategies and market conditions evolve, the asset allocation may change.

Market-based strategy seeks to deliver predictable earnings aligned to business needs and provide flexibility to adjust investment risk profile based on enterprise objectives and market opportunities primarily through public and private fixed income investments and public equity securities.

Performance-based strategy seeks to deliver attractive risk-adjusted returns and supplement market risk with idiosyncratic risk primarily through investments in private equity, including infrastructure investments, and real estate with a majority being limited partnerships. These investments include investee level expenses, reflecting asset level operating expenses on directly held real estate and other consolidated investments.

Fixed income securities

Fixed income securities are rated by third-party credit rating agencies or are internally rated. The Securities Valuation Office (“SVO”) of the National Association of Insurance Commissioners (“NAIC”) evaluates the fixed income securities of insurers for regulatory reporting and capital assessment purposes. The NAIC assigns securities to one of six credit quality categories defined as “NAIC designations”. In general, securities with NAIC designations of 1 and 2 are considered investment grade and securities with NAIC designations of 3 through 6 are considered below investment grade. The rating is either received from the SVO based on availability of applicable ratings from rating agencies on the NAIC Nationally Recognized Statistical Rating Organizations (“NRSRO”) provider list, including Moody’s Investors Service (“Moody’s”), S&P Global Ratings (“S&P”), Fitch Ratings (“Fitch”), or a comparable internal rating.

As a result of time lags between the funding of investments, the finalization of legal documents, and the completion of the SVO filing process, the portfolio includes certain securities that have not yet been designated by the SVO as of each balance sheet date and the categorization of these securities is based on the expected ratings indicated by internal analysis.

As of September 30, 2024, 91.4% of the consolidated fixed income securities portfolio was rated investment grade. Credit ratings below these designations are considered lower credit quality or below investment grade, which includes high yield bonds.

Market prices for certain securities may have credit spreads which imply higher or lower credit quality than the current third-party rating. Our initial investment decisions and ongoing monitoring procedures for fixed income securities are based on a due diligence process which includes, but is not limited to, an assessment of the credit quality, sector, structure, and liquidity risks of each issuer.

Fixed income portfolio monitoring is a comprehensive process to identify and evaluate each fixed income security that may require a credit loss allowance. The process includes a quarterly review of all securities to identify instances where the fair value of a security compared to its amortized cost is below internally established thresholds. For further detail on our fixed income portfolio monitoring process, see Note 5 of the condensed consolidated financial statements.
