How we computed this
The year is the calendar year the Federal Audit Clearinghouse accepted the filing (the accepted date, checkable on fac.gov). Nonprofit auditees only, one report per organization and audit year; a resubmission supersedes the filing it replaces. Only a year that has ended is published. Median is the middle filing by federal awards spent. A firm is identified by its Clearinghouse firm identifier; a firm filed under two names is one row only when the Clearinghouse gives it one identifier.
