Segment Disclosures [Abstract]

Segment Disclosures

Note 13. Segment Disclosures

Our reportable segments are Williams Partners, Williams NGL & Petchem Services, andAccess Midstream Partners. All remaining business activities are included in Other. (See Note 1.)

Performance Measurement

We currently evaluate 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. Intersegment revenues are generally accounted for at current market prices as if the sales were to unaffiliated third parties.

The following table reflects the reconciliation of segment revenues and segment profit (loss) to revenues and operating income (loss) as reported in the Consolidated Statement of Income and total assets by reportable segment
