Fannie Mae said today that it would make a $59.4 billion payment to the U.S. Treasury next month after reporting a $58.7 billion first-quarter profit thanks to a big tax benefit the bailed-out mortgage-finance company booked after determining it would generate profits in the coming years, the Wall Street Journal reported today. Fannie recognized $50.6 billion in tax benefits during the first quarter, in addition to pre-tax income of $8.1 billion during the period. That compared to a $2.7 billion gain during the year-earlier period. The tax boost stemmed from reversing write-downs of its deferred-tax assets, which are unused tax credits and deductions that can offset future tax bills but which are worthless if a company is not expected to turn a profit and have taxable income. The mortgage-finance company began writing down the tax benefits in 2008 as rising mortgage defaults threatened to wipe out thin capital reserves.
