Income Taxes

Provision for income taxes increased $6,936,918 to $8,840,782 during the three-month period ended March 31, 2014, as compared to the same period ended in 2013. The increase in income taxes was due to increased net income, which reflected $19,652,778 in milestone and contract revenue associated with our U.S. license agreement for MONOVISC (see the previous discussion under Note 10). The provisions for the periods ended March 31, 2014 and 2013 were based on effective tax rates of 37% and 38%, respectively. The decrease in the effective tax rate for the period ended 2014, as compared to the same period ended in 2013, was driven primarily by the tax benefits associated with the increase in production activities combined with the benefits associated with increased stock option exercise activity.

The Company files income tax returns in the U.S. on a federal basis, in certain U.S. states, and in Italy. The associated tax filings remain subject to examination by applicable tax authorities for a certain length of time following the tax year to which those filings relate. Our 2010 through the present tax years remain subject to examination by the IRS and other taxing authorities for U.S. federal and state tax purposes. The 2009 through the present tax years remain subject to examination by the appropriate governmental authorities in Italy.

In connection with the preparation of the financial statements, the Company performed an analysis to ascertain if it was more likely than not that it would be able to utilize, in future periods, the net deferred tax assets associated with its net operating loss carryforward. We have concluded that the positive evidence outweighs the negative evidence and, thus, those deferred tax assets are realizable on a “more likely than not” basis. As such, we have not recorded a valuation allowance at March 31, 2014 or December 31, 2013, respectively.
