Both GSEs are expected to need a draw from the U.S. Treasury, thanks to the passage of the Tax Cuts and Jobs Act that will reduce the corporate tax rate and result in $15.3 billion in one-time charges for the pair. With the tax rate being reduced from 35 percent to 21 percent, the GSEs now have to measure their net deferred tax assets using the new rate. According to recent Securities and Exchange Commission filings, Fannie Mae expects to take a one-time charge of $10.0 billion and Freddie Mac is bracing for a $5.3 billion charge.
