BACKGROUND On February 10, 2003, Interstate Power and Light Company (Interstate, IPL or the Company) petitioned the Minnesota Public Utilities Commission for approval of its March 31, 2004 proposed capital structure. More specifically, IPL sought approval of: o Interstate's requested March 31, 2004 capital structure with: - Common equity of 45.3 percent, - Preferred equity of 7.5 percent, and - Long-term Debt of 39.0 percent; o A contingency range of -/+25 percent range around Interstate's March 31, 2004 estimated common equity, preferred equity and long term debt; o Interstate's proposed total capitalization contingency, not to exceed 5 percent over its projected March 31, 2004 total capitalization, including $250 million of short-term debt (i.e., $2,451.8 million); and o Interstate's proposed short-term debt, not to exceed $250 million at any time during the fiscal year ending March 31, 2004. The Department's March 14, 2003 recommendation was as follows: o Approve Interstate's requested March 31, 2004 capital structure; o Approve a-/+ 10 percent range around Interstate's Pre-Equity Infusion Average common equity, preferred equity and long-term debt; Docket No. E,G001/S-03-187 Analyst assigned: Dale V. Lusti Page 2 o Approve a-/+ 10 percent range around Interstate's Post-Equity Infusion Average common equity, preferred equity and long-term debt; o Approve Interstate's total capitalization contingency, not to exceed 5 percent over its projected March 31, 2004 total capitalization, including $250 million of short-term debt (i.e., $2,451.8 million); o Approve Interstate's short-term debt, not to exceed $250 million at any time during the fiscal year ending March 31, 2004; and o Allow the Company not to seek Commission approval before issuing securities as long as issuing these securities will not result in a capital structure that is out of compliance with this Order. On March 28, 2003, the Commission approved the Department's recommendation as stated above. II. SUMMARY OF INTERSTATE'S PROPOSAL On July 22, 2003, Interstate petitioned the Commission for approval of an amendment to its March 31, 2004 proposed capital structure, effective beginning in August 2003. Due to current market conditions, IPL deems it advisable to move up its planned $35 million issuance of preferred stock from December 2003 to August 2003. If the issuance is moved up to August 2003, the preferred equity ratio in that month would likely fall outside the allowed range. As a result, IPL is seeking approval of the following new ranges for common equity, preferred stock and long-term debt: Post-Equity Infusion Revised Average August 2003 Through March 2004 Component Proposed Range Capital Structure ----------------------------------------------------------------------------- Common Equity 42.0%- 51.4% 46.7% Preferred Equity 7.6 - 9.3 8.5 Long-term Debt 36.8 - 45.0 40.9 IPL requests that the maximum total capitalization and the maximum short-term debt limits remain as previously ordered. Docket No. E,G001/S-03-187 Analyst assigned: Dale V. Lusti Page 3 III. DEPARTMENT ANALYSIS The Department believes that IPL has requested the revision to allow for the $35 million issuance of preferred stock during August 2003 rather than in December 2003 for the following two reasons: o First, IPL's parent (Alliant) infused only $119 million of common equity into IPL during July 2003 versus the anticipated $150 million identified in the initial petition which was the basis for the Commission's March 28, 2003 Order; and o Second, although IPL has not specifically identified the amount of savings, it expects that the interest rates will have increased by December 2003, thus making the issuance more costly. After discussion with the utility, the Department has determined that IPL's liquidity would not be detrimentally affected if the Commission determines not to approve IPL's requested revision. --- The Department agrees with Interstate that, absent a revision to the Commission approved capital structure, the Company would be outside its approved range for preferred equity beginning in August 2003. However, it should be noted that neither the common equity nor the long-term debt ratios would be outside the approved ranges. Similar to the Department's discussion in its March 14, 2003 Comments, the Department notes that the timing of a single equity issuance can have a large impact on the debt and equity ratios, resulting in a utility being out of compliance with its contingency ranges. Therefore, the Department agrees with Interstate that it is reasonable to modify the capital structure to reflect both the change in the timing of the preferred stock issuance as well as the most recent actual information and currently projected data. From a regulatory point of view, the use of a tightened contingency range as recommended by the Department and approved by the Commission in its Match 28, 2003 Order creates the occasional need for revisions such as this. This allows the Department and the Commission the opportunity to be fully aware of changes as they occur, and how the may affect ratepayers. As a result, the Department recommends that the Commission approve Interstate's proposed post-equity capital structure for the months August 2003 through March 2004. It should be noted that the month of August 2003, as compared to the month of July 2003 (as identified in the Commission's March 28, 2003 Order), should be the first month of the revised capital structure in that the preferred stock issuance will occur during the month of August 2003. Docket No. E,G001/S-03-187 Analyst assigned: Dale V. Lusti Page 4 One minor modification that the Department recommends is that Interstate be allowed a maximum capitalization contingency of $2,446.3 million (5 percent above its revised March 31, 2004 total capitalization of $2,329.8 million, including $250 million of short-term debt). The Department's calculation is based on the revised capitalization proposed in the filing rather than the one previously approved in the March 28, 2003 Order. IV. SUMMARY AND RECOMMENDATION The Department summarizes its recommendations to revise the Commission's March 28, 2003 Order as follows: o Approve Interstate's requested March 31, 2004 capital structure; o Approve a-/+10 percent range around Interstate's Post-Equity Infusion Average common equity, preferred equity and long-term debt; and o Approve Interstate's total capitalization contingency, not to exceed 5 percent over its revised projected March 31, 2004 total capitalization, including $250 million of short- term debt (i.e., $2,446.3 million). /jl RECEIVED Interstate Power and Light Co.
