(a)

During the three months ended June 30, 2013, we began applying regulatory accounting to another one of our pipeline systems due to a newly negotiated long-term tolling agreement approved by the system’s regulator that went into effect in April 2013. The primary impact of applying regulatory accounting, was the reclassification of approximately $362 million of current and long-term deferred credits to regulatory liabilities, of which $115 million remains classified as current. We expect this regulatory liability to be refunded to rate-payers over approximately the next four years.
