## Questions

### Who runs investment decisions at MD Sass?

Martin D. Sass has served as the firm's chief investment officer since founding in 1972, making him one of the longest-tenured active portfolio managers in the U.S. The firm's investment process has historically been highly centralized, with Sass directly overseeing security selection across equity and credit portfolios. There is no publicly known investment committee structure that dilutes his decision-making authority.

### Is MD Sass primarily an equity or fixed-income manager?

MD Sass has historically operated across equity, fixed-income, real estate, and private equity, though public equities have been its most persistently visible allocation. The firm's equity strategy has focused on deep value — distressed, out-of-favor, and small-cap companies with identifiable catalysts. The credit practice invested primarily in investment-grade and high-yield corporate bonds.

### How has MD Sass's corporate structure changed over time?

In 2019, the firm executed a restructuring that separated certain business lines and associated personnel from the original legal entity (per public filings, 2019). The details of which strategies or assets remained under the MD Sass name versus moved to successor entities have not been broadly disclosed, and the firm's current operational footprint is thinner than its historical peak.

### Does MD Sass accept outside institutional capital?

Historically yes — MD Sass managed separate accounts and commingled vehicles for pension funds, endowments, and high-net-worth individuals. The firm's mutual fund offerings have closed over time, and it is not clear whether the current entity is actively soliciting new discretionary mandates. No recent fund launches or capital closes have been publicly announced.

### What is MD Sass's known posture on private investments?

MD Sass has invested in private equity and real estate through a combination of direct deals and pooled vehicles. The real estate practice focused on commercial assets in secondary U.S. markets, and the private equity book targeted control and minority positions in small-to-mid-market companies, often those already known through the public equity research process. There is no publicly available track record for a dedicated private capital fund series.
