(a) In prior periods, the undistributed earnings of our Canadian subsidiaries were not designated as permanently reinvested. As of December 31, 2011, however, management asserts that the undistributed earnings of our Canadian subsidiaries are permanently reinvested. During the current year, we recognized a deferred tax benefit of $4,023, resulting from the release of the December 31, 2010 deferred tax liability.

(b) In 2011, the “Internal Revenue Code for a New Puerto Rico” was signed into law. Under the enacted legislation, the Puerto Rico corporate income tax rate was lowered from 39% to 30%. As a result, a non-cash charge of $1,743 to income tax expense was recorded for the reduction of the Puerto Rico net deferred tax asset.
