Fannie Mae expects to miss its March 18th deadline for filing fourth-quarter financial results, Reuters reported.

The government-controlled mortgage firm notified the Securities and Exchange Commission, saying they would not file the earnings report on time. Fannie expects to post significant net income for the three months and the year ending Dec. 31. 

Fannie Mae said it needs more time to analyze its deferred tax assets, which are unused credits and deductions that can be used to cover future tax bills, in the SEC filing it submitted on Thursday.
