[1] During the fourth quarter of 2013, we recorded income tax expense of $10.0 million related to prior quarters. This included U.S. tax on the sale of Canadian properties of $6.4 million and dividends from a Canadian joint venture of $3.6 million. This amount recorded in the fourth quarter was not material to prior quarters and, accordingly, the prior quarters have not been revised. On an after-tax basis, these items resulted in decreases to net income and diluted EPS of $10.0 million and $0.15, respectively.
