We incurred liabilities for construction in progress that had not been paid at March 31, 2012 and December 31, 2011 of $273.0 million and $286.9 million, respectively.  Such amounts are not included under the caption "Capital expenditures" on the Unaudited Condensed Statements of Consolidated Cash Flows.

              On certain of our capital projects, third parties are obligated to reimburse us for all or a portion of project expenditures.  The majority of such arrangements are associated with projects related to pipeline construction and production well tie-ins.  These cash receipts are presented as "Contributions in aid of construction costs" within the investing activities section of our Unaudited Condensed Statements of Consolidated Cash Flows.

Proceeds from asset sales and related transactions increased $914.0 million quarter-to-quarter, primarily from the sale of 26,331,868 common units of Energy Transfer Equity during the first quarter of 2012.  See Note 7 for information regarding our investment in Energy Transfer Equity.

See Note 10 for information regarding cash amounts attributable to noncontrolling interests.
