[1] A history of operating losses in recent years has led to uncertainty with respect to the Company’s ability to realize certain net deferred tax assets, and as a result, the Company recorded increased valuation allowances of $24.5 million, $4.2 million and $0.3 million, in the second, third and fourth quarters of fiscal 2014, respectively, against its U.S. net deferred tax assets.

[2] As a result of the expiration of the applicable statute of limitations relating to the tax audits in the U.S. for years 2008 through 2010, the Company recorded tax benefits of $9.0 million and $39.0 million, in the third quarter of fiscal 2014 and 2013, respectively.
