Income Taxes	5. Income Taxes We are calculating our effective income tax rate using a year-to-date income tax calculation, with the exception of one of our Puerto Rico subsidiaries for which we calculate the income tax expense based on our projected effective tax rate. Our income tax expense differs from the statutory federal tax rate of 35% and related statutory state tax rates, primarily due to the change in the valuation allowance on substantially all of our deferred tax assets with the exception of one of our Puerto Rico subsidiaries.

The tax years that remain subject to assessment of additional liabilities by the Puerto Rico tax authority are 2011 through 2014. From time to time, we have been and are subject to certain legal proceedings and claims that have arisen in the ordinary course of business, including an audit by a State tax authority (the “State”) for the income tax years from December 31, 2007 through 2009, which was settled and closed. The State audit did not result in a significant impact, as our tax positions were sustained. The State audit resulted in an additional tax liability of approximately $0.1 million, plus interest, related to capital taxes and not based on income. We do not anticipate the result of this audit to impact subsequent open tax years with the State, and thus have not set up a reserve. Based on our evaluation, we have concluded that there are no significant uncertain tax positions requiring recognition in our consolidated financial statements as of June 30, 2015 and December 31, 2014.

5. Income Taxes

We are calculating our effective income tax rate using a year-to-date income tax calculation, with the exception of one of our Puerto Rico subsidiaries for which we calculate the income tax expense based on our projected effective tax rate. Our income tax expense differs from the statutory federal tax rate of 35% and related statutory state tax rates, primarily due to the change in the valuation allowance on substantially all of our deferred tax assets with the exception of one of our Puerto Rico subsidiaries.

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 tax authorities are 2011 through 2014. The tax years that remain subject to assessment of additional liabilities by state and local tax authorities are 2010 through 2014. The tax years that remain subject to assessment of additional liabilities by the Puerto Rico tax authority are 2011 through 2014.

From time to time, we have been and are subject to certain legal proceedings and claims that have arisen in the ordinary course of business, including an audit by a State tax authority (the “State”) for the income tax years from December 31, 2007 through 2009, which was settled and closed. The State audit did not result in a significant impact, as our tax positions were sustained. The State audit resulted in an additional tax liability of approximately $0.1 million, plus interest, related to capital taxes and not based on income. We do not anticipate the result of this audit to impact subsequent open tax years with the State, and thus have not set up a reserve.

Based on our evaluation, we have concluded that there are no significant uncertain tax positions requiring recognition in our consolidated financial statements as of June 30, 2015 and December 31, 2014.
