Having abandoned their plans to create their own museum, Carol Vogel reports that Don and Doris Fisher will donate their collection to the SFMoMA which is in the middle of an expansion plan that will triple exhibition space:

The Fishers’ art — 1,100 works by major contemporary figures like Calder, de Kooning, Diebenkorn, Warhol and Lichtenstein, as well as by living artists like Cy Twombly, Ellsworth Kelly and Brice Marden — dovetails with the museum’s collection.

Under the agreement, the Fishers, who have long been trustees at the museum, will create a trust to oversee the care of the collection; the trust will be renewable after 25 years. The couple are also planning to make a significant contribution toward building the galleries, as well as a separate donation to the museum’s endowment.
