Income Taxes

The Company is subject to U.S. federal, state, and foreign income taxes. The Company recorded an income tax provision in its Statement of Operations of $133.4 million and $112.5 million for the three months ended June 30, 2015 and 2014, respectively, and $333.9 million and $225.0 million for the six months ended June 30, 2015 and 2014, respectively. The Company's effective tax rate was 40.7% and 53.9% for the three months ended June 30, 2015 and 2014, respectively, and 55.2% and 57.7% for the six months ended June 30, 2015 and 2014, respectively. The Company's effective tax rate for the three and six months ended June 30, 2015 was negatively impacted, compared to the U.S. federal statutory rate, by (i) losses incurred in foreign jurisdictions with rates lower than the U.S. federal statutory rate, (ii) the non-deductible Branded Prescription Drug Fee, and (iii) expiration, at the end of 2014, of the federal tax credit for increased research activities.

The Company's effective tax rate for the three and six months ended June 30, 2014 was negatively impacted by losses incurred in foreign jurisdictions with rates lower than the federal statutory rate and expiration at the end of 2013 of the federal tax credit for increased research activities. In addition, the Company's effective tax rate for the six months ended June 30, 2014 was negatively impacted by New York State tax legislation enacted in the first quarter of 2014. This tax legislation reduced the New York State income tax rate to zero percent for "qualified manufacturers", including Regeneron, effective in 2014; however, it also resulted in the Company reducing its related deferred tax assets as a discrete item in the first quarter of 2014. As a result, this tax legislation caused a net increase in the Company's effective tax rate by 3.9% for the six months ended June 30, 2014.

The Company also recorded an income tax benefit in its Statement of Comprehensive Income of $16.3 million and $18.9 million for the three and six months ended June 30, 2015, in connection with unrealized losses on available-for-sale marketable securities. For both the three and six months ended June 30, 2014, the Company recorded an income tax provision in its Statement of Comprehensive Income of $1.4 million in connection with unrealized gains on available-for-sale marketable securities.
