Segment Information

(22)  Segment Information

Puget Energy operates one business segment referred to as the regulated utility segment.  The regulated utility segment includes the account receivables securitization program which was terminated during the merger.  Puget Energy's regulated utility operation generates, purchases and sells electricity and purchases, transports and sells natural gas.  The service territory of PSE covers approximately 6,000 square miles in the state of Washington.

Non-utility business segment includes two PSE subsidiaries and Puget Energy, and is described as Other.  The PSE subsidiaries are a real estate investment and development company and a holding company for a small non-utility wholesale generator which was sold in 2010.  Reconciling items between segments are not significant.

Effective February 6, 2009, all merger related fair value adjustments were retained in Puget Energy.  Accordingly, only the financial statements of Puget Energy were adjusted to reflect the purchase accounting.  Prior to the merger, the business segment financial statements for Puget Energy and PSE were the same.
