Evaluating the underlying risks in our credit portfolio involves a multitude of factors including but not limited to our
assessment of the issuer's or borrower's business activities, assets, products, market position, financial condition, and
future prospects. We incorporate the assessment of the NRSROs in assigning credit ratings and we incorporate the rating
methodologies of our specialist external managers in assigning loan ratings to portfolio holdings. We perform extensive
internal assessments of the credit risks for all our portfolio holdings and potential new investments, which includes using
analyses provided by our specialist external managers. For assets managed by external asset managers, we provide
investment and credit risk parameters that must be used when making investment decisions and require ongoing
monitoring and reporting from the asset managers on significant changes in credit risks within the portfolio.
