Fannie Mae (FNMA)

[contrarian bull]

Do all businesses use DTA or is it just certain types of businesses get hammered by lower taxes that use DTA's?

Any company or individual that has a loss for the year would defer or carry over those losses into future years. Ha - after the stock market crash in 2000 I carried enough deferred tax losses to not pay a penny in state or federal income taxes for the next 4 years.... too much fun!

The Deferred Tax Asset is a way to monetize or account for those deferred/carryover losses on a balance sheet. So - only companies that issue annual reports with a balance sheet would explicitly use DTA's but any company or individual that had a tax loss would carry those over into future years.
