[1] Amounts for all periods presented differ from each respective Form 10-Q filing due to our acquisition of a controlling interest in New ARL on October 2, 2013, which is an entity under common control and which we consolidated on an as-if-pooling basis.

[2] We consolidated the results of CVR effective May 5, 2012.

[3] Basic and diluted income per LP unit is computed separately for each quarter and therefore, the sum of such quarterly per LP unit amounts may differ from the total for the year.
