Unum Group

Martha Davies Leiper has served as Executive Vice President and Chief Investment Officer since 2018. She oversees the general account investment portfolio, which exceeds $40 billion and supports the company's group disability, life, and supplemental health reserves. Leiper reports directly to CEO Richard P. McKenney and manages a team responsible for asset-liability matching, credit research, and commercial mortgage origination.

The portfolio is managed on a liability-driven basis, with asset allocations designed to match the duration and cash-flow profile of Unum's long-tail disability and life insurance claims. Investment-grade corporate bonds represent the largest allocation, followed by commercial mortgage loans, private placements, and structured securities. The firm benchmarks against liability cash flows rather than market indices, reflecting a statutory accounting framework where carrying value and book yield take priority over mark-to-market returns.

Yes, though alternatives represent a smaller portion of the general account relative to fixed income. Unum participates in private credit, middle-market direct lending, real estate equity, and limited partnership interests in select alternative funds. The commercial mortgage loan portfolio — a significant allocation — is originated directly by the firm's internal real estate team, targeting stabilized, income-producing industrial and multifamily properties.

As a state-regulated insurer governed by NAIC risk-based capital rules and rating agency surveillance, Unum must maintain specific capital ratios and asset quality thresholds. This regulatory framework creates a buy-and-maintain orientation: the firm acts as a steady, price-insensitive provider of private placement and commercial mortgage capital, prioritizing durable income and credit quality over total-return volatility.

The Unum Group Foundation is a corporate-funded vehicle separate from the general account investment portfolio. It directs grants toward education, workforce development, and community health initiatives in Chattanooga, Portland, Maine, and other operating locations. Foundation assets are managed independently and do not commingle with insurance reserves.

Public filings indicate Unum participates in limited partnerships and private placement transactions alongside other institutional investors, though explicit co-investment programs — where the firm invests in individual deals alongside a GP outside of a fund structure — are not prominently disclosed. The direct commercial mortgage origination program functions as the firm's primary vehicle for deal-level investment discretion.

The investment portfolio is primarily US-domiciled, consistent with the liability profile of Unum's American policyholders. The firm's UK subsidiary, Unum Limited, maintains a separate, locally regulated investment portfolio for its European operations, headquartered in Dorking, Surrey. The US general account commercial mortgage exposure is concentrated in the Southeast, Northeast, and select industrial markets nationally.
