Income Taxes	5. Income Taxes We have determined that due to a variety of reasons, we are currently unable to estimate our annual effective tax rate during our interim periods, which would be applied to our pre-tax ordinary income. We are calculating our effective income tax rate using a year-to-date income tax calculation. Our income tax expense differs from the statutory federal tax rate of 35% and related statutory state tax rates, primarily due to the reversal of our deferred tax liabilities related to the tax amortization of our FCC broadcasting licenses and the establishment of a valuation allowance on substantially all of our deferred tax assets. We file federal, state and local income tax returns in the United States and Puerto Rico. The tax years that remain subject to assessment of additional liabilities by the United States federal, state, and local tax authorities are 2009 through 2012. The tax years that remain subject to assessment of additional liabilities by the Puerto Rico tax authority are 2008 through 2012. Based on our evaluation, we have concluded that there are no significant uncertain tax positions requiring recognition in our consolidated financial statements as of March 31, 2013.
