INFORMATION TO BE INCLUDED IN THE REPORT ITEM 8.01 Other Events BOK Financial Corporation (the "Company"), through its wholly-owned subsidiary, Bank of Oklahoma, N.A. approved modifications to the retirement benefit plans offered to its employees. The objectives of these modifications are to provide competitive retirement benefits that reward long-term employee performance and provide employees with more control over their retirement savings. These modifications will become effective April 1, 2006. Changes to Company's Thrift Plans include increasing the maximum percentage of employee contribution subject to employer matching from 5% to 6% of compensation as defined by the plans, increasing the employer's matching contributions based on years of service, and implementing a maximum non-elective annual contribution of $750 for certain employees. Employer matching contributions will now range from 50 cents per dollar contributed by employees with less than four years of service to $2 per dollar contributed by employees with 15 or more years of service. In addition, the maximum after-tax employee contribution has been increased from 5% to 6% of compensation as defined by the plans. The Company also elected to curtail accruals for future service under its defined-benefit Pension Plan. Interest will continue to accrue on employees' account balances as provided by the Pension Plan. The Company will incur a charge of approximately $500,000 in the fourth quarter of 2005 for the curtailment of its Pension Plan. The combined effect of the modifications is not expected to have a significant impact on future earnings or liquidity. Signature Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
