INTERSTATE POWER COMPANY Summarized Financial Information The March 31, 1996 financial statements included herein have been prepared by the company, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. The accounting policies followed by the company are set forth in Note 1 to the company's financial statements in the 1995 Form 10-K/A. It is suggested that these condensed financial statements be read in conjunction with the financial statements and the notes thereto included in the company's Form 10-K/A for the year ended December 31, 1995. In the opinion of the company, the financial statements reflect all adjustments, consisting only of normal recurring accruals, necessary to fairly state the results of operations. INTERSTATE POWER COMPANY PART I - FINANCIAL INFORMATION Item 2. Management's Discussion and Analysis The company's results of operations and financial condition are affected by numerous factors, including weather, sales, and the amount of changes in customer rates. The dividend of $2.08 per share annually and $0.52 per quarter has been maintained. EARNINGS PER SHARE for the first quarter of 1996 were $0.93 compared to $0.74 for the corresponding period in 1995. Major contributors to the improved earnings were increased electric and gas sales due to colder weather, and rate increases in the Iowa electric, Iowa gas and Minnesota gas jurisdictions. The ELECTRIC MARGIN (revenue less cost of fuel and purchased power) for the first quarter of 1996 was $36.9 million compared to $34.9 million for the first quarter of 1995. The electric margin for the first quarter of 1996 reflects a 4.7% increase in residential sales, and a $6.6 million annual electric rate increase which became effective June 29, 1995. Three Months Ended March 31 ELECTRIC SALES (Mwh) 1996 1995 % Change Residential 281,350 268,769 4.7 Commercial 188,455 187,415 0.6 Industrial 774,179 768,701 0.7 Interchange 37,183 4,973 N/A Sales for Resale 61,022 64,049 (4.7) Other 15,663 15,537 0.8 Total Electric Sales 1,357,852 1,309,444 3.7 The 4.7% increase in sales to residential customers is primarily a result of cold weather this year. Residential electric heat usage was up 8.9%. Sales to commercial and industrial customers, which are less weather sensitive, increased 0.6% and 0.7%, respectively. The 4.7% decline in sales for resale is primarily attributable to reduced non-firm sales to one municipal resale customer. The higher interchange sales reflect the increased power marketing activities resulting in long-distance transmission of electric power, a trend which is expected to continue. Three Months Ended March 31 ELECTRIC REVENUES (000'S) 1996 1995 % Change Residential 20,052 19,185 4.5 Commercial 11,864 11,760 0.9 Industrial 28,635 28,235 1.4 Interchange 727 106 N/A Sales for Resale 2,065 2,188 (5.6) Other 2,572 2,329 10.4 Total Electric Revenues 65,915 63,803 3.3 The increase in residential, commercial and industrial electric revenues for the first quarter of 1996 compared to 1995 was due to the Iowa electric rate increase effective June 29, 1995, and the increase in residential kwh sales. The rate increase contributed approximately $0.04 per share to improved earnings and increased residential sales contributed approximately $0.03 per share. The increase in interchange sales did not significantly affect the electric margin nor net income, as the margin on such sales applicable to the Iowa jurisdiction is flowed back to customers through the fuel adjustment clause. The GAS MARGIN (revenue less purchased gas) for the first quarter of 1996 was $9.7 million compared to $9.0 million for the same period in 1995. Factors in the improved gas margin include the increased temperature sensitive sales to residential and commercial customers, and rate increases in the Iowa and Minnesota gas jurisdictions. Interim Iowa gas rates in an annual amount of $1.3 million were implemented October 20, 1995, while interim Minnesota gas rates in an annual amount of $1.5 million were implemented June 30, 1995. The Iowa and Minnesota gas rates increases contributed $0.5 million and $0.7 million, respectively, to the first quarter of 1996 gas margin. COST OF GAS SOLD increased $1.5 million, or 15.2%, during the first quarter of 1996 compared to the same period in 1995 primarily due to the 7.4% increase in volumes sold and a 3.7% increase in the unit cost of gas due to colder weather. Three Months Ended March 31 GAS DELIVERIES (MMcf) 1996 1995 % Change Residential 2,484 2,231 11.3 Commercial 1,403 1,275 10.0 Industrial 387 467 (17.1) Other 5 11 N/A Total Gas Sales 4,279 3,984 7.4 Gas Transportation 6,701 6,616 1.3 Total Gas Deliveries 10,980 10,600 3.6 The increase in residential and commercial gas sales is mainly a result of 11.4% colder temperatures in 1996. Although industrial sales were down, volumes transported to industrial customers increased, resulting in total industrial deliveries of approximately the same level for the first quarter of 1996 and the first quarter of 1995. Three Months Ended March 31 GAS REVENUES (000's) 1996 1995 % Change Residential $12,496 $11,053 13.1 Commercial 6,441 5,657 13.9 Industrial 1,482 1,587 (6.6) Other 49 59 N/A Total Gas Sales Revenues 20,468 18,356 10.3 Gas Transportation 666 607 9.7 Total Gas Revenues $21,134 $18,963 11.5 The increase in residential and commercial revenues is primarily a result of increased sales due to colder temperatures. The rate increases contributed approximately $0.075 per share to improved earnings and increased residential sales contributed approximately $0.03 per share. Revenue from retail industrial sales decreased mainly as a result of the decreased sales. There have been no significant developments concerning FERC Order 636 transition costs since the company's discussion of this matter in the 1995 Annual Report to Stockholders. ACCOUNTS RECEIVABLE were $29.6 million at March 31, 1996 compared to $27.8 million at December 31, 1995 and $25.0 million at March 31, 1995. The increase was mainly due to the colder weather which resulted in higher revenues, and the electric and gas rate increases implemented in 1995. FUEL FOR ELECTRIC GENERATION decreased $2.1 million, or 12.3%, in the first quarter of 1996 compared to the same period in 1995. The decrease was due to a 7.3% reduction in kilowatt-hours generated by the company. The cost of gas used for generation decreased $1.0 million compared to last year. Greater quantities of gas were burned at the Fox Lake Power Plant during the first quarter of 1995 due to lower gas costs. In 1995, the company entered into new coal supply agreements which are estimated to reduce 1996 prices over 7.0% compared to 1995 prices. PURCHASED POWER EXPENSE increased $2.1 million, or 17.3%, during the first quarter of 1996 compared to 1995. This increase is primarily a result of the 27.2% increase in Kwh's. Capacity charges included in purchased power expense were $5.8 million for both the first quarter of 1996 and the first quarter of 1995. During the first quarter of 1996, the company realized revenues of $30,000 and transmission service expenses of $44,000 under the intra-pool transmission service fee requirement of the MAPP Agreement. OTHER OPERATING EXPENSE included merger related expense of approximately $0.2 million during the first quarter of 1996. Expenses totaled approximately $1.5 million for the twelve months ended March 31, 1996. See ITEM 5, OTHER INFORMATION for details concerning the merger. DEPRECIATION EXPENSE increased by $0.4 million or 4.9%. This is primarily due to increased investment in utility plant and increased depreciation rates approved by the Minnesota Public Utilities Commission in September 1995. Total INCOME TAX EXPENSE increased approximately $1.1 million during the first quarter of 1996 compared to the first quarter of 1995 mainly due to higher income. Net income before taxes was $15.5 million for the first quarter of 1996 compared to $12.6 million for the same period in 1995. OTHER INCOME for the first quarter of 1996 includes $0.4 million of energy efficiency carrying costs and curtailment credits compared to $0.3 million for the same period in 1995. The increase is primarily due to an increase in the total amount of demand side management (DSM) costs ($24.1 million at March 31, 1996 compared to $18.2 million at March 31, 1995). The 1991 and 1992 DSM costs are being recovered over a four year period beginning in October 1994. The company filed an application with the Iowa Utilities Board (IUB) on April 30, 1996 for recovery of the 1993, 1994 and 1995 DSM costs. The application seeks recovery of an annual amount of $7.3 million over a four year period. The IUB is expected to issue a final order by October 31, 1996. INTEREST ON LONG-TERM DEBT decreased approximately $0.2 million during the first quarter of 1996 compared to the same period in 1995. On May 1, 1995, $14,000,000 of 4 5/8% Series First Mortgage Bonds were retired. OTHER INTEREST EXPENSE decreased approximately $13,000 primarily due to interest on short-term borrowings. Short-term interest expense was $429,000 for the first quarter of 1996 compared to $448,000 for the first quarter of 1995. The average outstanding balance of short-term borrowings during the first quarter of 1996 was $30.3 million compared to $29.9 million during the first quarter of 1995. Interest rates for the first quarter of 1996 averaged 5.6% compared to 6.0% in 1995. AVERAGE TEMPORARY INVESTMENTS during the first quarter of 1996 were $2.9 million compared to $1.9 million in 1995. The average interest rate was 5.4% in the first quarter of 1996 compared to 5.7% in 1995. FUEL INVENTORIES were $11.9 million at March 31, 1996, compared to $19.3 million at December 31, 1995 and $15.5 million at March 31, 1995. The decline in inventories from December 31st is primarily due to normal seasonal draw-down of coal supplies during the winter when the river is closed to barge traffic. CONSTRUCTION EXPENDITURES totaled $4.8 million during both the first quarter of 1996 and the first quarter of 1995. There were no major individual construction projects during the first quarter of 1996. Construction work in progress as of March 31, 1996 totalled $3.9 million compared to $8.4 million at March 31, 1995. The 1996 and 1997 construction programs are estimated to be $32 million and $36 million, respectively. The company does not anticipate any public offerings for new debt or new stock in the next two years, other than for re-establishing the Dividend Reinvestment Program whereby new shares will be purchased on the open market, beginning either in the second or third quarter of 1996. In 1993 the company adopted Statement of Financial Accounting Standards (SFAS) 106, "EMPLOYER'S ACCOUNTING FOR POSTRETIREMENT BENEFITS OTHER THAN PENSIONS". Under the provisions of SFAS 106, the estimated future cost of providing postretirement benefits will be accrued during the employees' service periods. The Iowa Utilities Board has allowed the company to recover SFAS 106 costs in its Iowa gas rates effective May 1993 and Iowa electric rates effective October 1993. As of March 31, 1996, the company has deferred approximately $2.1 million of SFAS 106 costs applicable to its Minnesota jurisdiction pending approval of the company's request for recovery of the costs in rate increase applications filed in 1995. The company filed an Iowa electric rate increase application in March 1995. The application requested an annual increase of $13.1 million. Interim rates in an annual amount of $7.1 million were placed in effect on June 29, 1995, subject to refund. A December 1995 Iowa Utilities Board (IUB) Order allowed an annual increase of $6.6 million, including a return on common equity of 11.35%. The company's original rate increase request included a return on common equity (ROE) and a management efficiency reward which totaled 13.25%. The IUB allowed a ROE of 11.35% and no efficiency reward. The lower ROE granted will not have a significant adverse impact on operating results. Revenues collected in excess of the Board's ordered level in the amount of approximately $270,000 were refunded in April 1996. The company filed a Minnesota electric rate increase application with the Minnesota Public Utilities Commission (MPUC) in June 1995. The application requested an annual increase of $4.6 million (later adjusted by the company to $3.3 million). The proposed tariffs include a seasonal rate mechanism similar to that used in the State of Iowa. Interim rates were not requested. On March 8, 1996 the MPUC received the report of the Administrative Law Judge (ALJ) hearing the case. The ALJ recommended a $2.3 million revenue increase. The major component of the $1.0 million reduction in revenue requirements is the disallowance of the Minnesota portion of 100 MW of purchased power contracts. The disallowance is similar to a ruling in a previous rate case, thus, is not expected to have any additional material adverse impact on the company's financial condition. On April 10, 1996 the Commission issued an order allowing an increase in electric rates of $2.3 million. On April 26, 1996, the company filed for reconsideration of the purchased power disallowance by the Commission. The Commission is expected to respond to the request before the end of the third quarter of 1996. The company filed an Iowa gas rate increase application in August 1995. The application requested an annual increase of $2.2 million. Interim rates in an annual amount of $1.3 million were placed in effect on October 20, 1995, subject to refund. The IUB Order dated February 21, 1996, approved the $1.1 million increase in revenue requirements for the company's Iowa gas jurisdiction. The increase represents a 3.5% increase in rates to Iowa gas customers. Iowa gas rates implemented in October 1995 did not include recovery of any future investigative or remediation costs to be incurred in the clean-up of former manufactured gas plants. The company anticipates that future investigation and remediation costs applicable to the Iowa jurisdiction, if required, will be recovered from customers after a rate filing. The company filed a Minnesota gas rate increase application in May 1995. The application requested an annual increase of $2.4 million, including a return on common equity of 11.75%. Interim rates in an annual amount of $1.5 million were placed in effect in June 1995, subject to refund. A MPUC Order issued February 29, 1996 allowed an annual increase of $2.1 million and a return on common equity of 10.75%. On March 20, 1996 the Minnesota Department of Public Service and the Office of the Attorney General both requested reconsideration of the MPUC Order. The $2.1 million increase in revenues included in the MPUC Order represented a 24% increase in rates for Minnesota gas customers. The return on equity granted by the MPUC (10.75%) is lower than expected, however, it is within a reasonable range and the lower rate will not have a material adverse impact on the company's financial condition. Final resolution of the MPUC Order is expected in 1996. The company's potential liability for coal tar waste at former manufactured gas plant sites was discussed in the 1995 Annual Report to Stockholders. With regard to the nine sites, clean-up has been completed at one site and ground water monitoring will continue for at least one more year. At another site, remediation of the site will begin in May 1996. For the remainder of the other seven sites, testing and soil sampling are continuing, but the company is unable to determine what, if any, remediation will be necessary until a later date.
