"On March 20, 2013, TPL filed a petition under Chapter 11 of the United States Bankruptcy Code (see Note 8). We have been appointed to the creditors’ committee and will be closely monitoring the progress in this matter as it relates to our interest in PDS. In the event that we provide funding to PDS that is not reciprocated by TPL, which would result in our having a larger ownership percentage in PDS, we will have a controlling financial interest in PDS, in which case, we will consolidate PDS in our consolidated financial statements. If we determine that it is appropriate to consolidate PDS, we would measure the assets, liabilities and noncontrolling interests of PDS at their fair values at the date that we have the controlling financial interest."
