Low Interest Rate Environment Risk: Sustained low interest rates can reduce investment income, impacting profitability and increasing the cost of maintaining policy reserves.

Actuarial and Underwriting Risk: Inaccurate assumptions in pricing policies, estimating future claims (mortality, morbidity), or managing claims can lead to higher-than-expected payouts and financial losses.

Investment Portfolio Risk: Fluctuations in equity markets, credit defaults within the bond portfolio, or declines in real estate values can negatively impact the value of Unum's investment assets and overall financial health.
