The effective income tax rate of a benefit of approximately 24.0% for the first half of 2014 differs from the United States federal statutory rate of a benefit of 35% principally as a result of non-deductible goodwill impairment, U.S. tax on unremitted earnings, losses in certain jurisdictions that cannot be benefited, and uncertain tax positions, partially offset by the impact of foreign rates. Compared to the United States federal statutory rate of a benefit of 35%, the effective income tax rate of a benefit of approximately 16.3% for the first half of 2013 differs principally as a result of losses in certain jurisdictions that cannot be benefited and the settlement of an uncertain tax position during the first quarter of 2013. The Company has recorded approximately $3.8 million of realized tax benefits related to deductions for share-based compensation in excess of the corresponding book expense to additional paid in capital in the first half of 2014.

The Company accounts for share-based compensation deductions on the basis that these are the last tax benefits that are utilized. As of January 1, 2014, the Company had a liability of approximately $20.8 million for unrecognized tax benefits related to various federal, foreign and state income tax matters.

As of June 28, 2014 and December 31, 2013, the amount of uncertain tax positions that will impact the Company's effective tax rate is approximately $11.5 million and $10.9 million, respectively. The difference between the total amount of uncertain tax positions and the amount that will impact the effective tax rate represents the federal tax effect of state tax items, items that offset temporary differences, and items that will result in the reduction of other tax assets. As of June 28, 2014, the Company had approximately $3.9 million in unrecognized benefits relating to various tax issues, for which the statute of limitations is expected to expire in 2014.
