INCOME TAXES
The effective income tax rate was 42.2% for the three months ended March 31, 2015, compared to 46.4% for the three months ended March 31, 2014. The effective tax for the three months ended March 31, 2015 includes the beneficial effect of a deferred tax asset recorded in connection with the held-for-sale classification of our Concentra subsidiary, decreasing our effective tax rate by approximately 7 percentage points, partially offset by an increase in the non-deductible health insurance industry fee from 2014. Humana Inc., our parent company, recognized the deferred tax asset for the excess of the tax basis over the book basis of its Concentra subsidiary of approximately $53 million during the first quarter of 2015 because realization of the asset in the foreseeable future was apparent with the classification as held-for-sale.
