Business Context and Reporting Period
This Form 8-K, dated January 6, 2012, reports on a material definitive agreement entered into by Arizona Public Service Company (APS), a subsidiary of Pinnacle West Capital Corporation. The filing details a settlement agreement regarding APS's pending general retail rate case, which requires approval by the Arizona Corporation Commission (ACC).
Key Financial Metrics and Agreement Terms
The Settlement Agreement provides for a zero net change in base rates, structured as follows:
- Non-fuel base rate increase: $116.3 million.
- Fuel-related base rate decrease: $153.1 million (implemented by reducing the base fuel rate from $0.03757 to $0.03207 per kWh).
- Renewable Energy Surcharge transfer: Estimated $36.8 million transferred to base rates.
Key regulatory and financial parameters established in the agreement include:
- Return on Common Equity: Authorized at 10.0%.
- Capital Structure: 46.06% debt and 53.94% common equity.
- Test Year: Ended December 31, 2010, adjusted for plant in service as of March 31, 2012.
- Environmental Improvement Surcharge (EIS): Modifications allow recovery of carrying costs for environmental controls, subject to a cap producing approximately $5 million annually.
Material Changes and Stay-Out Provisions
APS has agreed to a "stay-out" period regarding future rate filings:
- No new general rate case filing before May 31, 2015.
- No request for a general retail rate increase effective prior to July 1, 2016.
Exceptions allow for rate adjustments during this period in the event of extraordinary events requiring public interest protection or significant regulatory developments materially impacting financial results. The agreement also introduces a "Lost Fixed Cost Recovery" mechanism and modifies the Power Supply Adjustor (PSA) by eliminating the 90/10 sharing provision.
Outlook, Risks, and Contingencies
Implementation Timeline: If approved by the ACC, the provisions are expected to become effective on or about July 1, 2012. An evidentiary hearing is scheduled to commence on January 26, 2012.
Regulatory Risk: The filing explicitly states that APS cannot predict whether the Settlement Agreement will be approved in the form filed. Approval by the ACC is a material contingency.
Property Tax Deferrals: The agreement includes specific deferral mechanisms for property taxes based on rate changes: 25% deferral in 2012, 50% in 2013, and 75% for 2014 and subsequent years if rates increase; 100% deferral in all years if rates decrease.
