Business Context and Reporting Period
This Form 8-K is a combined current report filed by Pinnacle West Capital Corporation and its subsidiary, Arizona Public Service Company (APS), dated February 1, 2006. The filing addresses results of operations and financial condition for the fiscal quarter and fiscal year ended December 31, 2005, and discloses a significant regulatory event regarding a general rate case.
Key Financial Metrics and Regulatory Requests
Specific revenue, profit, cash flow, and debt figures for the period ended December 31, 2005, are not contained within the text of this Form 8-K. The filing references Exhibits 99.2, 99.3, 99.7, 99.9, and 99.10 for detailed financial statements and statistical summaries.
However, the filing details a specific regulatory request by APS to the Arizona Corporation Commission (ACC) regarding annual retail electricity revenues:
- Updated Revenue Request: $453.9 million increase (21.3% increase).
- Original Revenue Request: $409.1 million increase (19.9% increase).
- Proposed Rate Base: Approximately $4.4 billion (as of September 30, 2005).
- Proposed Capital Structure: 45% long-term debt and 55% common stock equity.
- Weighted-Average Cost of Capital: 8.73% (5.41% for debt, 11.50% for equity).
Material Changes and Regulatory Updates
On January 31, 2006, APS filed updated financial schedules for its general rate case, changing the test period from the year ended December 31, 2004, to the twelve months ended September 30, 2005. This change resulted in an increased request for revenue recovery.
The primary driver for the increased request is higher fuel and purchased power costs. The breakdown of the updated request versus the original filing is as follows:
| Cost Component | Updated Request ($ Millions) | Updated Request (%) | Original Request ($ Millions) | Original Request (%) |
|---|---|---|---|---|
| Increased fuel and purchased power | $299.0 | 14.0% | $246.8 | 12.0% |
| Capital structure update | $98.3 | 4.6% | $96.8 | 4.7% |
| Rate base update (incl. Sundance Power Plant) | $46.2 | 2.2% | $42.5 | 2.1% |
| Pension funding | $41.3 | 1.9% | $41.2 | 2.0% |
| Other items | ($30.9) | (1.4%) | ($18.2) | (0.9%) |
| Total Increase | $453.9 | 21.3% | $409.1 | 19.9% |
The updated request does not include a separate Power Supply Adjustor (PSA) rate increase of approximately 5% effective February 1, 2006, or any PSA surcharges.
Guidance, Outlook, and Risks
Management Commentary: The company notes that the information provided in the exhibits is preliminary and subject to significant adjustment. Some data is based on third-party information and may contain inaccuracies.
Regulatory Risk: The requested rate increase is contingent upon approval by the ACC. If the base rate increase for fuel and purchased power costs is approved, future PSA rate adjustments or surcharges would be reduced.
Unusual Items: The filing highlights the acquisition of the Sundance Power Plant as a component of the rate base update.
Investor Verification Checklist
- Review Exhibit 99.9 (Earnings News Release) and Exhibit 99.7 for specific revenue, net income, and earnings per share figures for the quarter and year ended December 31, 2005.
- Monitor the Arizona Corporation Commission's decision on the updated general rate case filed January 31, 2006, specifically regarding the 21.3% revenue increase request.
- Verify the impact of the Sundance Power Plant acquisition on the company's rate base and future capital expenditures.
- Assess the sensitivity of future earnings to fuel and purchased power costs, given these represent the largest portion of the requested rate increase.
- Confirm the status of the Power Supply Adjustor (PSA) mechanism and how the approved base rate will interact with future PSA surcharges.
