The following is a reconciliation of the federal tax calculated at the statutory rate of 35% to the actual income taxes provided (in thousands):

Temporary differences comprising deferred taxes on the Consolidated Balance Sheets are as follows (in thousands):

A deferred tax valuation allowance is required when it is more likely than not that all or a portion of deferred tax assets will not be realized. At June 30, 2011, the Company had provided a valuation allowance for potential capital loss carryovers resulting from excess tax basis in certain of its equity investments. During fiscal 2012, the Company determined that the valuation allowance was no longer necessary as a result of the Company’s unrealized gain on its CCXI investment. The Company has the intent and ability to sell a portion of its CCXI investment and realize a long-term capital gain to offset losses on its investments in unconsolidated entities. The Company believes that it is more likely than not that the recorded deferred tax assets will be realized.

During fiscal 2013, the Company’s R&D Europe subsidiary declared and paid a dividend of £20 million ($30.7 million) to the Company. The £20 million R&D Europe earnings had previously been taxed in the U.S. and therefore, no additional U.S. tax resulted from the repatriation. Undistributed earnings of the Company’s foreign subsidiaries amounted to approximately $144 million as of June 30, 2013. Deferred taxes have not been provided on such undistributed earnings, as the Company has either paid U.S. taxes on the undistributed earnings or intends to indefinitely reinvest the undistributed earnings in the foreign operations.

A summary of changes in unrecognized tax benefits is as follows (in thousands):

The gross unrecognized tax benefit balance as of June 30, 2013, 2012 and 2011 includes $1,000, $2,000 and $3,000, respectively, of unrecognized tax benefits that, if recognized, would affect the effective tax rate. Accrued interest and penalties were not material at June 30, 2013 and 2012.

The Company does not believe it is reasonably possible that the total amounts of unrecognized tax benefits will significantly increase or decrease in the next twelve months. The Company has files income tax returns in the U.S federal tax jurisdiction, the states of Minnesota, Massachusetts and California, and several jurisdictions outside the U.S. U.S. tax returns for 2010 and subsequent years remain open to examination by the tax authorities. The Company’s major non-U.S. tax jurisdictions are the United Kingdom, France and Germany, which have tax years open to examination for 2010 and subsequent years, and China, which has calendar year 2013 open to examination.
