Private Foundation donates a chunk to another qualified organization. Letter comes back from the qualified organization that goods or services were received. Goods or services were given to a non-related party. How is that handled on the 990?
Are you saying that the goods or services to the unrelated party in no way benefited or had anything to do with the PF (or its related parties)? And that therefore the acknowledgment is in error, presumably because the other organization did not understand the meaning? If so, get a corrected acknowledgment - soon.
