Occasionally OSF will make a grant to encourage a grantee organization to broaden its base of support by requiring that the grantee match all or a part of the OSF's grant. The grantee is required to match funds at a fixed rate (e.g., for a 1:1 grant of $50,000, the grantee must raise $50,000. OSF may award a 1 to 2 contingency (1:2), meaning that for a grant of $50,000, the grantee must raise $100,000. Occasionally, a 1:3 or 1:4 match may be used. A matching award must be satisfied with cash, pledges, and sometimes in-kind assets. A matching grant can be multi-year and there may be annual caps on matching amounts for each year.
