Report of Independent Accountants To the Participants and Plan Administrator of the Wisconsin Electric Power Company Employee Retirement Savings Plan In our opinion, the accompanying statements of net assets available for benefits and the related statements of changes in net assets available for benefits present fairly, in all material respects, the net assets available for benefits of the Wisconsin Electric Power Company Employee Retirement Savings Plan (the "Plan") at December 31, 1999 and 1998, and the changes in net assets available for benefits for the years then ended, in conformity with accounting principles generally accepted in the United States. These financial statements are the responsibility of the Plan's management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these statements in accordance with auditing standards generally accepted in the United States, which require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for the opinion expressed above. Our audits were performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule of Assets Held for Investment Purposes at End of Year is presented for the purpose of additional analysis and is not a required part of the basic financial statements but is supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. This supplemental schedule is the responsibility of the Plan's management. The supplemental schedule has been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole. /s/PricewaterhouseCoopers LLP - ------------------------------------------ PRICEWATERHOUSECOOPERS LLP Milwaukee, Wisconsin June 7, 2000 Wisconsin Electric Power Company Employee Retirement Savings Plan Statements of Net Assets Available for Benefits December 31, 1999 and 1998 - -------------------------------------------------------------------------------- 1999 1998 ------------ ------------ Assets Investments (See Note 3) $552,629,548 $460,763,002 Cash 685,121 1,335,145 ------------ ------------ Net assets available for benefits $553,314,669 $462,098,147 ============ ============ <FN> The accompanying notes are an integral part of these financial statements. </FN> Wisconsin Electric Power Company Employee Retirement Savings Plan Statements of Changes in Net Assets Available for Benefits For the Years Ended December 31, 1999 and 1998 - -------------------------------------------------------------------------------- 1999 1998 ------------ ------------ Additions - --------- Additions to net assets attributed to: Investment income: Interest and dividends $35,794,997 $23,316,534 Net appreciation in fair value of investments 20,383,798 36,488,660 ------------ ------------ 56,178,795 59,805,194 ------------ ------------ Contributions: Participants' 32,058,293 30,229,463 Employer's 8,559,449 7,793,332 ------------ ------------ 40,617,742 38,022,795 ------------ ------------ Total additions 96,796,537 97,827,989 Deductions - ---------- Deductions from net assets attributed to: Administrative expenses 40,401 30,300 Benefits paid to participants 14,858,902 14,236,649 ------------ ------------ Total deductions 14,899,303 14,266,949 ------------ ------------ Net increase prior to plan transfer 81,897,234 83,561,040 Transfer from another plan (See Note 1) 9,319,288 - ------------ ------------ Net increase 91,216,522 83,561,040 Net assets available for benefits: Beginning of year 462,098,147 378,537,107 ------------ ------------ End of year $553,314,669 $462,098,147 ============ ============ <FN> The accompanying notes are an integral part of these financial statements. </FN> Wisconsin Electric Power Company Employee Retirement Savings Plan Notes to Financial Statements December 31, 1999 and 1998 - -------------------------------------------------------------------- 1. Description of the Plan The following description of the Wisconsin Electric Power Company ("WE" or the "Company") Employee Retirement Savings Plan ("ERSP" or the "Plan") provides only general information. Participants should refer to the plan agreement for a more comprehensive description of the Plan's provisions. General The Plan is a defined contribution plan covering all employees of WE who are projected to complete at least 1,000 hours of service within one year from hire date. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 ("ERISA"). During 1999, the Plan was amended to reflect the merger of the Bargaining Unit Savings Plan of Edison Sault Electric Company and the Employee Incentive and Stock Plan of Edison Sault Electric Company. Net assets totaling $9,319,288 were transferred to the Plan. Contributions Contributions are subject to certain limitations of the Internal Revenue Code ("IRC"). Participants are allowed to make a pre-tax contribution of up to 20% of their base wages, as defined in the Plan. Participants are also allowed to contribute to the Plan on a post tax basis and may contribute amounts representing distributions from other qualified defined benefit or defined contribution plans. The Company matches 50% of the first 6% of wages up to a maximum contribution of 3% of qualified compensation, as defined in the Plan. All employer contributions are initially invested in the Wisconsin Energy Corporation ("WEC") Common Stock Fund. Participant Accounts Each participant's account is credited with the participant's contribution and allocations of (a) the Company's contribution and (b) Plan earnings. Allocations of plan earnings are based on participant account balances in relation to total fund account balances as defined in the Plan. Earnings on investments are not taxed while such amounts accumulate in the Plan. The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested account balance. Forfeited balances of terminated participants' nonvested accounts are used to reduce future employer contributions. Vesting Participants are immediately vested in their contributions plus actual earnings thereon. Vesting in the Company's matching contribution portion of their account plus actual earnings thereon occurs after the participant achieves 1,000 hours of service. Investment Options Participant contributions may be allocated, in whole percentages, to any of various investment options offered by the Plan. Participants may change their investment options daily. The value of participant investments in the Blended Rate Income Fund grows through earnings at negotiated interest rates, while investment growth (loss) in mutual funds results from dividends plus a net increase (decrease) in the market value of securities in the fund. Participant Withdrawals and Terminations The full value of a participant's ERSP account is distributed through a lump-sum cash payment to the employee or designated beneficiary upon retirement, termination of employment or death, for account balances less than $5,000. Distributions of participant account balances of $5,000 or greater are based on participant elections in accordance with the Plan provisions. As the Plan is primarily designed to meet long-term financial needs, employees may permanently withdraw amounts from their accounts under the terms of the Plan's financial hardship withdrawal guidelines. Additionally, participants may withdraw all or a portion of the value of their after-tax contributions, however, this withdrawal is limited to once per Plan year. Participant Notes Receivable Participants may borrow from their fund accounts up to the lesser of 50% of their account balance or $50,000, reduced by the highest outstanding loan balance over the past 12 months. Loans are repayable monthly over periods not to exceed 5 years. The interest rate charged on participant loans is fixed at the beginning of each loan at prime rate plus 1%. Plan Termination Although it has not expressed any intent to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of Plan termination, participants will become 100% vested in their accounts. Administration A trustee is utilized in connection with the operation of the Plan. The Chief Financial Officer and Vice President-Finance of WE serves as the Plan Administrator. 2. Significant Accounting Policies Basis of Accounting The Plan's financial statements are prepared under the accrual basis of accounting. Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and changes therein, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates. Investment Valuation The investments of the Plan are stated at fair value, except for its investments in guaranteed investment contracts which are stated at contract value. Participant loans are stated at cost which approximates fair value. Shares of mutual funds and common stock are valued at quoted market prices on the last day of the plan year. The Plan's investments in traditional guaranteed investment contracts and synthetic guaranteed investment contracts are valued at contract value because participants may ordinarily direct the withdrawal or transfer of all or a portion of their investment at contract value. Contract value represents contributions made under the contract, plus earnings, less withdrawals and administrative expenses. The contract value of the Plan's investments in guaranteed investment contracts approximates fair value at December 31, 1999 and 1998. The average yield for the Plan's investments in guaranteed investment contracts was 6.0% and 6.3% for the years ending December 31, 1999 and 1998, respectively. The crediting interest rate was 5.9% and 5.7% as of December 31, 1999 and 1998, respectively. Risks and Uncertainties The Plan's investments are exposed to various risks, such as interest rate, market and credit risks. Due to the level of risk associated with certain investments and the level of uncertainty related to changes in the values of investments, it is at least reasonably possible that changes in risks in the near term could materially affect participants' account balances and the amounts reported in the statements of net assets available for benefits and the statements of changes in net assets available for benefits. Income Recognition The Plan presents in the statements of changes in net assets available for benefits the net appreciation in the fair value of its investments, which consists of the realized gains or losses and the unrealized appreciation (depreciation) on those investments. Interest and dividends are recorded as earned. Payments of Benefits Benefits are recorded when paid. Administrative Expenses All significant administrative expenses are paid by the Company, except for loan origination fees which are paid by the borrowing participant and charged against the fund from which the borrowings are made. Reclassifications Certain reclassifications have been made to the December 31, 1998 financial statements to conform to the presentation used in the current year. 3. Investments The following presents investments that represent 5% or more of the Plan's net assets: December 31, -------------------------------------- --- 1999 1998 ------------ ------------ WEC Common Stock, 4,702,518 and 3,496,250 shares, respectively $90,523,472 $109,914,813 Fidelity Equity Income Fund, 1,590,167 and 1,467,790 shares, respectively 85,042,129 81,535,742 Fidelity Growth Company Fund, 1,700,984 and 1,354,683 shares, respectively 143,392,914 69,115,947 Fidelity U.S. Equity Index Commingled Pool, 1,812,046 and 1,682,467 shares, respectively 76,214,639 58,617,135 During 1999 and 1998, the Plan's investments (including gains and losses on investments bought and sold, as well as held during the year) appreciated in value by $20,383,798 and $36,488,660, respectively, as follows: 1999 1998 ------------ ------------ Mutual funds $52,269,985 $14,740,045 Collective trust fund 12,984,530 12,311,002 Common stock (44,870,717) 9,437,613 ----------- ----------- $20,383,798 $36,488,660 =========== =========== 4. Tax Status The Internal Revenue Service has determined and informed the Company by a letter dated September 21, 1995, that the Plan is designed in accordance with applicable sections of the IRC. The Plan has been amended since receiving the determination letter. However, the plan administrator and the Plan's tax counsel believe that the Plan is designed and is currently being operated in compliance with the applicable requirements of the IRC. 5. Amounts Allocated to Withdrawn Participants Plan assets of $112,294,075 and $86,312,273 have been allocated to the accounts of persons who are no longer active participants of the Plan as of December 31, 1999 and 1998, respectively. 6. Unitization of the WEC Common Stock Fund The WEC Common Stock Fund is accounted for on a unitary basis. At December 31, 1999, there were 9,086,423.348 units in the fund with a net asset value of $10.04 per unit. At December 31, 1998, there were 6,812,612.273 units in the fund with a net asset value of $16.33 per unit. 7. Party-in-interest Transactions Certain plan investments represent shares of mutual funds managed by Fidelity Management Trust Company, shares of employer securities, and participant loans. These transactions are considered party-in-interest transactions. These transactions are not, however, considered prohibited transactions under 29 CFR 408(b) of the ERISA regulations.
