The instrument tables on municipal securities and loans (tables F.211 and L.211) have been revised from 2004:Q1 forward to reflect a change in data sources. Data on debt outstanding and net issuance for state and local governments, nonprofit organizations, and nonfinancial corporate business

outstanding in 2004:Q1 is $740 billion greater than previously estimated in the flow of funds accounts.
The estimate of household holdings of municipal securities and loans is revised up by about $840 billion, on average, from 2004 forward.
