During the first quarter of 2014, the Company determined it was more likely than not that a portion of the federal and state net operating losses it expects to generate in 2014 will not be realized based on projections of future taxable income. Accordingly, the estimated annual effective rate for the year ended December 31, 2014 includes a valuation allowance for that portion. In applying the estimated annual effective rate to earnings, the Company increased its valuation allowance by $18.3 million for the three months ended June 30, 2014 and $42.1 million for the six months ended June 30, 2014 relating to federal and state net operating losses.
