Federal regulators reminded banks Thursday to include new data on noninterest-bearing deposits and reverse mortgages among other additions to their fourth-quarter call reports.

The call reports, which are due to the agencies Jan. 30, must specify an institution's amount of noninterest-bearing checking deposits above the standard insurance limit of $250,000.

The Dodd-Frank Act requires total coverage of such deposits at all institutions until the end of 2012.

The Federal Deposit Insurance Corp. had been providing blanket coverage for participants in a voluntary program it started in late 2008, when wide-scale liquidity concerns led regulators to offer extensive guarantees.

But that program was set to expire Friday, which was also the start date for the mandatory coverage under Dodd-Frank.

New call-report entries require institutions to include not only the dollar amount but also the number of noninterest-bearing transaction accounts that exceed the $250,000 limit.

To reflect the new temporary coverage, the reporting requirements also adjust how institutions report total uninsured deposits.

The regulators also announced three new memorandum items related to an institution's reverse mortgages. As of Dec. 31, the information on reverse mortgages will be collected annually, the agencies said.
