Segment Disclosures

Note 18 – Segment Disclosures

Our reportable segments are Williams Partners, Williams NGL & Petchem Services, and Access Midstream Partners. All remaining business activities are included in Other. (See Note 1 – Description of Business, Basis of Presentation, and Summary of Significant Accounting Policies.)

Our segment presentation of Williams Partners is reflective of the parent-level focus by our chief operating decision-maker, considering the resource allocation and governance provisions associated with this master limited partnership structure. WPZ maintains a capital and cash management structure that is separate from ours. WPZ is self-funding and maintains its own lines of bank credit and cash management accounts. These factors, coupled with a different cost of capital from our other businesses, serve to differentiate the management of this entity as a whole.

Our segment presentation of Access Midstream Partners reflects the significant size of this investment and the economic opportunities it represents in major unconventional producing areas that add diversity to our current asset base.

Performance Measurement

We currently evaluate segment operating performance based upon Segment profit (loss) from operations, which includes Segment revenues from external and internal customers, segment costs and expenses, Equity earnings (losses) and Income (loss) from investments. General corporate expenses represent Selling, general, and administrative expenses that are not allocated to our segments. The accounting policies of the segments are the same as those described in Note 1 – Description of Business, Basis of Presentation, and Summary of Significant Accounting Policies. Intersegment revenues are generally accounted for at current market prices as if the sales were to unaffiliated third parties.

The following geographic area data includes Revenues from external customers based on product shipment origin and Long-lived assets based upon physical location.

			United States		Canada		Total
			(Millions)
Revenues from external customers:
	2013	$	6,703	$	157	$	6,860
	2012		7,335		151		7,486
	2011		7,728		202		7,930
Long-lived assets:
	2013	$	19,260	$	1,240	$	20,500
	2012		16,940		880		17,820
	2011		12,041		583		12,624

Long-lived assets are comprised of property, plant, and equipment, goodwill, and other intangible assets.

As discussed in Note 1 – Description of Business, Basis of Presentation, and Summary of Significant Accounting Policies and Note 4 – Discontinued Operations, our former exploration and production business was spun-off on December 31, 2011 and has been reported as discontinued operations in all prior periods presented. Revenues derived from intercompany sales to our former exploration and production business, previously reported as internal, are now shown as external. These sales were $310 million for the year ended 2011. In addition, costs attributable to activities with our former exploration and production business, previously reported as internal, are now shown as external. Such costs were $845 million for the year ended 2011. We continue to recognize revenue as we provide certain gathering, processing, and treating services to WPX under long term agreements.

The following table reflects the reconciliation of Segment revenues and Segment profit (loss) to Total revenues and Operating income (loss) as reported in the Consolidated Statement of Income and Other financial information related to Long-lived assets.
