[1] Quarterly amounts may not add to annual amounts due to the effect of rounding on a quarterly basis.

[3] For the third quarter, net income includes a $26.0 million gain on our previously held interest in Deer Park upon the acquisition of an additional one-third interest in August 2013, and the consolidation of Deer Park into our financial statements.
[4] In 2014 and 2013, adjustments of the noncontrolling interest were made as a result of increases in the Company's ownership of the Operating Partnership from additional units received in connection with the Company's issuance of common shares upon exercise of options, share-based compensation and the issuance of common shares upon exchange of Class A common limited partnership units.
