In some cases, those nonprofits closing their doors are not weak in terms of profile or contributions. What they share, however, is a fatal vulnerability in their funding mix, where the loss of one funding source can bring the system crashing down. This may happen only gradually, and the causes may differ: a key state contract may be cut, earned income may dry up, a major funder may decide an organization is no longer a priority. But in each case, the effect is much the same. Once a funding vacuum opens up, organizational leadership is stuck with a decision: is recovery possible, and is recovery worth it?
