Corona Asset Management XVIII won Fannie Mae’s fourth Community Impact Pool of nonperforming loans. Last week’s announcement represented the first time that the pool was sold to a private equity firm instead of a nonprofit group. The Community Impact Pool is structured to encourage nonprofits, as well as smaller investors and minority- and women-owned businesses. It’s designed to include geographically focused, high-occupancy collateral where bidders have a longer than usual time to participate in hopes of attracting diverse participation. Fannie began marketing this particular pool to possible bidders back in June with Bank of America Merrill Lynch and CastleOak Securities, L.P.
