Business Context and Reporting Period

Key Financial Metrics
The filing text does not provide specific financial data, including revenue, profit, cash flow, margins, debt, or liquidity figures. This report focuses exclusively on a regulatory event rather than financial performance.
Material Changes
The primary material event is the ACC's unanimous approval on December 15, 2010, of a modified decoupling policy statement. This policy supports a "revenue-per-customer" methodology, which APS and other parties advocated for. This represents a change from the draft policy issued in October 2010 and establishes a framework for future rate cases.
Guidance, Outlook, and Management Commentary
- Policy Impact: Decoupling reduces the linkage between sales volumes and utility revenues, removing disincentives for utilities to promote energy-saving programs.
- Mechanism: The policy allows utilities to file decoupling proposals in their next general rate case, where differences between actual and authorized revenues are credited or collected from customers in subsequent periods.
- Future Action: APS intends to include a decoupling model consistent with this policy statement in its upcoming general rate case, which is currently expected to be filed in mid-2011.
