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 in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit 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. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, such financial statements present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2000 and 1999, 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 of America. Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedules listed in the Table of Contents are presented for the purpose of additional analysis and are not a required part of the basic financial statements, but are 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. These schedules are the responsibility of the Plan's management. Such schedules have been subjected to the auditing procedures applied in our audit of the basic 2000 financial statements and, in our opinion, are fairly stated in all material respects when considered in relation to the basic financial statements taken as a whole. /s/ Deloitte & Touche LLP Boston, MA June 22, 2001 3 AMERICAN TOWER RETIREMENT SAVINGS PLAN STATEMENTS OF NET ASSETS AVAILABLE FOR BENEFITS DECEMBER 31, 2000 AND 1999 -------------------------------------------------------------------------------- 2000 1999 ---- ---- ASSETS: Investments, at fair value: Mutual funds $19,042,137 $8,982,545 Common stock 427,784 -- Participant loans 375,131 56,862 ----------- ---------- Total investments 19,845,052 9,039,407 Contributions receivable 725,052 461,892 ----------- ---------- NET ASSETS AVAILABLE FOR BENEFITS $20,570,104 $9,501,299 =========== ========== See notes to financial statements 4 AMERICAN TOWER RETIREMENT SAVINGS PLAN STATEMENTS OF CHANGES IN NET ASSETS AVAILABLE FOR BENEFITS YEARS ENDED DECEMBER 31, 2000 AND 1999 -------------------------------------------------------------------------------- 2000 1999 ----------- ---------- ADDITIONS: Investment activity: Net (depreciation) appreciation in fair value of investments $(2,024,684) $1,184,010 Dividends and interest 1,207,588 498,163 ----------- ---------- Net investment activity (817,096) 1,682,173 ----------- ---------- Contributions: Participant 10,361,677 3,538,144 Employer 1,525,372 500,622 ----------- ---------- Total contributions 11,887,049 4,038,766 ----------- ---------- Total additions 11,069,953 5,720,939 ----------- ---------- DEDUCTIONS: Benefits paid to participants (789,938) (327,175) Administrative expenses (47,837) (29,767) ----------- ---------- Total deductions (837,775) (356,942) ----------- ---------- NET INCREASE BEFORE TRANSFERS 10,232,178 5,363,997 TRANSFERS IN FROM OTHER PLANS 836,627 2,110,720 ----------- ---------- NET INCREASE 11,068,805 7,474,717 NET ASSETS AVAILABLE FOR BENEFITS: Beginning of year 9,501,299 2,026,582 ----------- ---------- End of year $20,570,104 $9,501,299 =========== ========== See notes to financial statements. 5 AMERICAN TOWER RETIREMENT SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS 1. DESCRIPTION OF THE PLAN The following description of the American Tower Retirement Savings Plan (the "Plan") provides only general information. Participants should refer to the Plan agreement for a more complete description of the Plan's provisions. GENERAL INFORMATION - The Plan, effective July 14, 1998, is a defined contribution plan available to substantially all full-time employees of American Tower Corporation and subsidiaries (the "Company"). The Company, as Plan administrator, controls and manages the operation and administration of the Plan. Fidelity Management Trust Company serves as the trustee of the Plan. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 ("ERISA"). PARTICIPANT CONTRIBUTIONS - Each year, participants may contribute up to 15% of pretax annual compensation, as defined in the Plan, subject to limits set by the Internal Revenue Code (the "Code"). Participants may also contribute amounts representing distributions from other qualified plans. EMPLOYER CONTRIBUTIONS - Each year, the Company may make discretionary matching contributions to be determined annually based on a percentage of an employee's pretax contributions. Matching contributions are subject to a maximum of 5% of an employee's eligible compensation contributed to the Plan. For 2000 and 1999, the matching contribution was 35% and 30%, respectively, of the first 5% contributed by a participant. PARTICIPANT ACCOUNTS - Each participant's account is credited with the participant's contributions and withdrawals, as applicable, and allocations of (a) the Company's contributions and (b) Plan earnings. Allocations are based on participant earnings or account balances, as defined. The benefit to which a participant is entitled is the benefit that can be provided from his or her account. VESTING - Participants are immediately vested in their contributions plus actual earnings thereon. Vesting in the Company contribution portion of their accounts (plus actual earnings thereon) is based on years of credited service. A participant will vest 20% each year until fully vested. PAYMENT OF BENEFITS - Total or partial cash distributions from the Plan are permitted upon a participant's attainment of age 59 1/2, termination of employment, retirement, death or disability. In addition, withdrawals are also permitted for certain events that result in financial hardship to the participant. A participant may make only one withdrawal in any consecutive 12-month period. FORFEITURES - Unvested employer contributions and earnings thereon that have been forfeited are initially applied against administrative expenses of the Plan. Any excess forfeitures are applied to reduce future employer contributions. 6 1. DESCRIPTION OF THE PLAN (CONTINUED) PARTICIPANT LOANS - Participants may borrow from their accounts a minimum of $1,000. The maximum amount is the lesser of one-half of a participant's vested account balance or $50,000, reduced by the highest outstanding loan balance in a participant's account during the prior 12-month period. Loans are fully secured by the participant's vested interest in his or her account. Loan terms generally range from one to 10 years. Participant loans bear interest at a rate commensurate with local prevailing rates as determined quarterly by the Plan administrator. The applicable interest rates for outstanding loans ranged from 7.5% to 9.5% as of December 31, 2000 and 1999. Principal and interest are paid ratably through semi-monthly payroll deductions. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES METHOD OF ACCOUNTING - The accompanying financial statements have been prepared on the accrual basis of accounting. Purchases and sales of securities are recorded on a trade-date basis. Dividends are recorded on the ex-dividend date. Interest is recorded when earned. USE OF ESTIMATES - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect certain reported amounts and disclosures. Accordingly, actual results may differ from those estimates. INVESTMENT VALUATION - Investments are stated at fair value based on quoted market prices. Participant loans are stated at cost, which approximates fair value. EXPENSES - All expenses are paid by the Plan or the Company, as provided for in the Plan document. PAYMENT OF BENEFITS - Benefits are recorded when paid. 3. INVESTMENTS Investments representing five percent or more of the Plan's net assets as of December 31 are as follows: 2000 1999 ---- ---- Fidelity Growth Company Fund $4,935,728 $2,976,055 Fidelity Growth & Income Portfolio 3,373,840 1,671,617 Fidelity Magellan Fund 3,019,695 1,155,605 Fidelity Retirement Money Market Portfolio 2,069,239 745,435 Spartan U.S. Equity Index Fund 2,059,015 969,910 Fidelity Worldwide Fund 1,567,018 712,939 Fidelity Puritan Fund 1,286,623 558,991 7 3. INVESTMENTS (CONTINUED) During the years ended December 31, 2000 and 1999, the Plan's investments (including gains and losses on investments bought and sold, as well as held, during the year) (depreciated) appreciated in value as follows: 2000 1999 ---- ---- Mutual funds $(2,014,931) $1,184,010 Common stock (9,753) -- ----------- ---------- Total $(2,024,684) $1,184,010 =========== ========== 4. NONPARTICIPANT-DIRECTED INVESTMENTS At December 31, 2000 and 1999, the Plan had nonparticipant-directed investments representing loans to participants in the amount of $375,131 and $56,862, respectively. The amount of interest income on loans for the years ended December 31, 2000 and 1999 was $10,168 and $2,755, respectively. 5. PLAN TERMINATION AND AMENDMENTS Although it has not expressed any intention to do so, the Board of Directors of the Company has the right under the Plan to suspend its contributions at any time and to terminate the Plan subject to the provisions set forth in ERISA. In the event of any termination of the Plan, or upon complete or partial discontinuance of contributions, the accounts of each affected participant shall become fully vested. The Board of Directors of the Company also has the right to amend the Plan, in whole or in part, subject to the provisions of ERISA. During 2000, the Plan was amended to (i) add Class A common stock of American Tower Corporation as an investment option, (ii) increase the Company's discretionary matching contribution to 35% of the first 5% of each employee's contribution for 2000, and (iii) exclude from the Plan the following classes of employees: employees covered by a collective bargaining agreement, leased employees, nonresident aliens who do not receive any U.S. source income, independent contractors, seasonal employees, student interns, and employees under student cooperative programs. 6. TAX STATUS The Plan has not yet received a determination letter from the Internal Revenue Service regarding the Plan's compliance with the applicable provisions of the Internal Revenue Code (the "Code"). However, the Company believes that the Plan is currently designed and being operated in accordance with the provisions of the Code. Accordingly, no provision for income taxes has been included in the Plan's financial statements. 7. RELATED-PARTY TRANSACTIONS The Plan's investments as of December 31, 2000 and 1999 include shares of mutual funds managed by Fidelity Management Trust Company, the plan trustee. In addition, investments include shares of common stock of American Tower Corporation, the plan sponsor. These transactions qualify as party-in- interest transactions. 8 8.
