The underlying securities may include commercial mortgage-backed securities, asset-backed securities, agency and non-agency residential mortgage-backed securities, collateralized mortgage obligations, and collateralized loan obligations. It may also hold agency mortgage-backed securities and fixed-rate or adjustable-rate securities. Up to 20% of the portfolio may be allocated to high-yield ratings and comparable unrated debt. Constituents are selected using a top-down and bottom-up approach, incorporating analysis of market risk, financial market conditions, real economic developments, and areas of credit excess.
