DBRS Limited (DBRS Morningstar) assigned a provisional rating of A (low) with a Stable trend to Sun Life Financial Inc.'s (SLF or the Company) Limited Recourse Capital Notes Series 2021-1 (Subordinated Indebtedness).

DBRS Morningstar assigned the rating equal to the Company's Issuer Rating of A (high) less two rating notches, which is consistent with DBRS Morningstar's notching approach for capital instruments issued by insurance holding companies. This is one notch below the rating of SLF's Subordinated Unsecured Debentures.

RATING DRIVERS

Given the already high rating level and uncertain macroeconomic environment, a ratings upgrade is unlikely in the near term. In the longer term, an upgrade could arise from continued progress with SLF's business diversification strategy while maintaining a conservative risk profile, as well as from an improvement in asset quality, including having a larger proportion of higher-rated bonds (rated 'A' or higher) in its investment portfolio.

The ratings would be downgraded if the Canadian business, a strong contributor to overall results, were to report a sustained decline in earnings, indicating a weakened franchise. Moreover, a substantial decline in regulatory capital levels or a sustained deterioration in financial leverage over 30% would result in a downgrade.
