Immaterial Correction of Prior Period Financial Statements

Immaterial Correction of Prior Period Financial Statements

During the period ended June 30, 2013, the Company determined certain immaterial corrections were required for previously-issued financial statements as discussed below. The corrections did not impact the Company’s operating income and were not considered material to the Company’s revenues and costs for the applicable periods.

The Company determined that revenues and purchased gas costs related to a new processing arrangement were improperly reduced from revenue and purchased gas costs which resulted in equal understatements of revenues and purchased gas costs in its previously-issued financial statements for the three and nine months ended September 30, 2012. As a result both revenues and purchased gas were understated by $38.0 million and $135.4 million for the three and nine months ended September 30, 2012, respectively. The following table reflects the revenues, purchased gas costs and total operating costs and expenses as previously reported and as adjusted for the three and nine months ended September 30, 2012 (in thousands):
