MML Investment Advisers, LLC

MML Investment Advisers is an SEC-registered investment adviser and a wholly owned subsidiary of Massachusetts Mutual Life Insurance Company (MassMutual) that manages pooled investment vehicles rather than individual retail accounts. It serves as adviser to 54 open‑end MassMutual Funds and provides discretionary advisory services to trust companies operating collective investment trusts (CITs), overseeing roughly $24.5 billion in discretionary assets as of December 31, 2025.

The firm generally operates as a “Manager of Managers,” selecting, allocating among, and monitoring subadvisers who make day‑to‑day portfolio decisions, and it serves as the portfolio manager for certain Funds of Funds by determining allocations among underlying funds. Its investment due diligence combines qualitative and quantitative analysis and emphasizes subadvisers and multi‑manager sleeves designed to produce consistent risk‑return profiles across market cycles.

Distinctive features include a broad network of MassMutual affiliates that interact with the Adviser’s business: affiliated broker‑dealer and distributor entities (MML Distributors and MML Investors Services), an affiliated asset manager (Barings) that serves as a subadviser to several Funds, and a bank/trust affiliate, among others. Those affiliations are reflected in the Adviser’s operational role—providing fund administrative and shareholder servicing support, participating in commission‑recapture and recordkeeper arrangements, and overseeing affiliated subadvisers—so the firm documents and discloses related conflict‑management and oversight practices.
