Sun Life Financial Inc.
Sun Life sells insurance, retirement savings, and health plans, and manages investments for people and institutions.
Sun Life is a Canadian financial company that sells protection and savings to ordinary people and to big organizations. If you buy life insurance, a health plan through your employer, or a retirement product that pays you income for life, there is a good chance a company like Sun Life is behind it. It also runs an asset management arm that invests money on behalf of pension funds, governments, and individuals.
The business splits into a few main parts. In Canada, it is one of the big names in group benefits — the dental, drug, and disability coverage that employers hand to workers — plus individual life insurance and retirement savings. In the United States, it focuses on specialty health and dental benefits, along with stop-loss insurance, which protects employers from unusually large medical claims. Its asset manager, MFS Investment Management, runs mutual funds and institutional portfolios, and it also has growing operations in Asia selling insurance and savings products. On top of that, Sun Life has a division that lends money to mid-sized companies and invests in real estate and infrastructure. How does it make money? Insurance customers pay premiums, and the company pays out claims. The gap between what it collects and what it pays — plus the investment returns on the money it holds in the meantime — is the profit. In asset management, it earns fees based on how much money it manages. That fee stream is steady and scales nicely, but it swings with markets: when stocks fall, assets shrink and fees fall with them. Insurance is the opposite — slow, boring, and reliable, which is exactly what makes it valuable.
Sun Life is a mature, dividend-paying company. It returns a big chunk of its spare cash to shareholders through dividends and share buybacks, and it has spent years trimming its footprint — it sold its UK business and much of its annuities book — to focus on Canada, the US, Asia, and asset management. Its main competition comes from other big Canadian insurers like Manulife Financial and Great-West Lifeco, as well as US health insurers, and its asset manager competes with giants like BlackRock. The biggest risks are low interest rates, which squeeze insurance profits, and market crashes, which hit the asset management fees.
