Commitments and Contingencies

We lease certain facilities, pipelines and rights of way under operating leases, most of which contain renewal options. The right of way agreements have various termination dates through 2053.

As of December 31, 2011, the minimum future rental commitments under operating leases having non-cancelable lease terms in excess of one year are as follows:

	(In thousands)
Years Ending December 31,
2012	$	6,668
2013	6,665
2014	6,609
2015	6,609
2016	6,608
Thereafter	3,795
Total	$	36,954

Rental expense charged to operations was $7.4 million, $7.1 million and $7.1 million for the years ended December 31, 2011, 2010 and 2009, respectively.

We are a party to various legal and regulatory proceedings, none of which we believe will have a material adverse impact on our financial condition, results of operations or cash flows.
