BOK Financial Thrift Plan for Hourly Employees Notes to Financial Statements December 31, 2001 1. DESCRIPTION OF PLAN The following description of the BOK Financial Thrift Plan for Hourly Employees (the Plan) provides only general information. Participants should refer to the Summary Plan Description or the Plan document for a more complete description of the Plan's provisions. General The Plan is a defined contribution plan covering all employees of BOK Financial Corporation (BOKF) and its subsidiaries and affiliates (collectively, the Employer or Company) who have attained age 21 and one year of service (equivalent to 1,000 hours) and who are compensated on an hourly basis, except those covered under a collective bargaining agreement and those treated as independent contractors. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). Contributions Participants may elect to contribute up to 12% of their compensation (as defined by the Plan) on a pre-tax basis pursuant to a salary reduction agreement filed with the Plan administrator. In addition, participants may make after-tax contributions to the Plan. The sum of the percentage of pre-tax and after-tax contributions shall not exceed 20% of each participant's compensation. Participants may elect investment in any of ten mutual funds, self-directed common stocks or registered investment companies, and BOKF Common Stock. The Employer contributes a matching contribution to the Plan. The matching contribution may be made in cash or in shares of BOKF Common Stock. In 2001, the entire matching contribution of $24,652 was made in cash. 1. DESCRIPTION OF PLAN (CONTINUED) For 2001, the Employer matching contribution ranges from $.40 to $1.00 for each dollar of the participant's contribution, up to 5% of compensation, based on each participant's years of service as follows: Years of Service Matching Percentage -------------------------------------------------- ------------------------- Less than three years 40% At least three, but less than seven, years 60% At least seven, but less than ten, years 80% Ten or more years 100% The Employer may in its sole discretion, make an additional discretionary contribution to the Plan. There was no discretionary contribution in 2001. Participant Accounts Each participant's account is credited with the participant's contribution and allocations of (a) the Employer's contribution and (b) Plan earnings. Allocations are based on participant earnings or account balances, as defined by the Plan. The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested account. Vesting Participants vest in Employer matching contributions based upon years of service, as defined by the Plan. Participants are 100% vested upon completion of five years of service and are immediately vested in their deferred (pre-tax) contributions, after-tax contributions, and the actual earnings thereon. Loans Participants may borrow against their accounts in amounts not less than $1,000 and not to exceed the lesser of $50,000 or 50% of the participant's vested account balance. Loans will bear interest based on the current banking prime rate and may not exceed a five-year term, unless it is used to acquire the primary residence of the participant, in which case the maximum term may be 25 years. The loans are secured by the balance in the participant's account. Interest rates range from 7.5% to 9.5%. Repayment is made by payroll withholdings. 1. DESCRIPTION OF PLAN (CONTINUED) Payment of Benefits A participant who terminates employment with a vested account balance less than $5,000 will receive a lump-sum payment. If the participant has a vested balance which exceeds $5,000, the Plan will make a distribution only with the consent of the participant at any time prior to the earlier of the participant's 65th birthday or death. In lieu of a lump-sum payment, a participant who terminates employment after his or her 65th birthday or after attaining age 60 and completing 10 years of service, shall be entitled to elect monthly, quarterly, semi-annual or annual installment payments to be paid over a period not to exceed 10 years from the benefit commencement date. The installments may be accelerated at the direction of the participant. Forfeitures Forfeited balances of terminated participants' nonvested accounts are utilized to pay administrative costs or to reduce future Employer contributions. During 2001, forfeitures of $856 were used to reduce Employer matching contributions. Plan Termination The Employer expects to continue the Plan indefinitely. However, the Employer reserves the right to discontinue the Plan or to amend the Plan, in whole or in part, from time-to-time. In the event of Plan termination, participants will become 100% vested in their accounts. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Accounting The financial statements of the Plan are prepared on the accrual basis of accounting. Administrative Expenses The Employer pays all administrative expenses of the Plan, except for loan origination fees, which are paid by the participants. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) Investment Valuation and Income Recognition Shares of registered investment companies are valued at published market prices which represent the net asset value of shares held by the Plan at year-end. The BOKF common stock is valued at the quoted market price. Participant loans receivable are valued at cost which approximates fair value. Purchases and sales of securities are recorded on a trade-date basis. Dividend income is recorded on the ex-dividend date. Interest income is recorded on the accrual basis. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. 3. INVESTMENTS The Plan's investments are held by a bank administered trust fund at Bank of Oklahoma, N.A. Trust Division (the Trustee). During 2001, the Plan's investments (including investments purchased and sold, as well as held during the year) appreciated/(depreciated) in fair value as determined by quoted market prices for BOKF common stock and published market prices for registered investment companies as follows: Net Appreciation (Depreciation) in Fair Value of Investments -------------------------- BOK Financial Corporation Common Stock $15,050 Registered Investment Companies (7,651) -------------------------- $ 7,399 ========================== The fair value of individual investments that represent 5% or more of the Plan's net assets are separately identified in the financial statements. 4. INCOME TAX STATUS The Plan has received a determination letter from the Internal Revenue Service dated April 1, 2002, stating that the Plan is qualified under Section 401 of the Internal Revenue Code (the Code) and, therefore, the related trust is exempt from taxation. Once qualified, the Plan is required to operate in conformity with the Code to maintain its qualification. The Plan administrator believes the Plan is being operated in compliance with the applicable requirements of the Code and therefore, believes that the Plan is qualified and the related trust is tax exempt.
