AM Best has upgraded the Long-Term Issuer Credit Ratings (Long-Term ICR) to aa from aa- and affirmed the Financial Strength Rating (FSR) of A+ (Superior) of Sun Life Assurance Company of Canada (Sun Life) (Ontario, Canada) and Sun Life and Health Insurance Company (U.S.) (SLHIC) (Lansing, MI) “ the core insurance subsidiaries of Sun Life Financial Inc. (SLF) (Ontario, Canada) [NYSE: SLF] (collectively referred to as Sun Life Group). Concurrently, AM Best has upgraded the Long-Term ICR to a from a- and existing Long-Term Issue Credit Ratings (Long-Term IR) of SLF.

Additionally, AM Best has upgraded the FSR to A- (Excellent) from B++ (Good) and the Long-Term ICR to a- from bbb+ of Independence Life & Annuity Company (Independence) (Wilmington, DE), a strategic subsidiary of SLF, to reflect the increased strategic importance of the companys operation. Lastly, AM Best has affirmed the FSR of B++ (Good) and the Long-Term ICR of bbb+ of Professional Insurance Company (Dallas, TX), an SLF run-off subsidiary. The outlook of these Credit Ratings (ratings) is stable. (Please see below for a detailed listing of the Long-Term IRs.)

The ratings of Sun Life Group reflects its balance sheet strength, which AM Best categorizes as strongest, as well as its strong operating performance, favorable business profile and very strong enterprise risk management (ERM).

The upgrade of Sun Life Groups Long-Term ICRs reflects the continued strength and evolution of the organizations ERM capabilities in relation to its risk profile. The groups risk culture and governance is well-defined and embedded within all levels of the organization. Sun Life Group also conducts an extensive array of sensitivity and stress testing beyond what is required by regulators including impacts on earnings, regulatory capital and liquidity. The results assist the company in setting its risk appetite and tolerances, as well as to evaluate exposures versus risk limits in many different categories. AM Best expects that the groups risk management practices will continue to evolve favorably, driven by strategies and innovation in line with other leading insurers.

Sun Life Groups ERM also reflects its generally stable operating performance and solid balance sheet position. The group maintains a very strong level of risk-adjusted capitalization, as measured by Bests Capital Adequacy (BCAR), and strong liquidity throughout the organization with strong cash flows, moderate financial leverage, a liquid investment portfolio, and a significant amount of cash and short-term investments at the holding company as an additional buffer. The balance sheet also continues to be bolstered by favorable earnings in its core segments while continuing to grow overall revenue.

While the company has focused on reducing volatility within the liability structure of its product offerings in recent periods, Sun Life Groups earnings remain moderately exposed to equity market volatility and changes in interest rates, as well as fluctuations in foreign currencies. AM Best notes the continuation of net outflows within the groups asset management business in recent periods. While this has been mitigated by generally favorable equity markets during this time, the groups earnings remain susceptible to increased volatility within the financial markets.

The ratings of Independence reflect its balance sheet strength, which AM Best categorizes as very strong, as well as its marginal operating performance, very limited business profile and very strong ERM.

The rating upgrades of Independence reflect its increased strategic importance to its parent, as it is anticipated to start writing stop-loss insurance in 2020. AM Best believes that Independence will benefit from its parent companys significant experience in the stop-loss insurance market and synergies from its turnkey administrative platform.

The ratings of Professional Insurance Company reflect its balance sheet strength, which AM Best categorizes as strongest, as well as its marginal operating performance, very limited business profile and very strong ERM.
