BOK FINANCIAL CORPORATION NASDAQ: BOKF For Further Information Contact: Danny M. Boyd Corporate Communications (918) 588-6348 Jim Ulrich Investor Relations (918) 588-6135 BOK FINANCIAL CORPORATION REPORTS RECORD 2002 EARNINGS Non-interest Revenue, Expansion Reinforce Growth TULSA, Okla. (Wednesday, Jan. 22, 2003)--A combination of solid loan and deposit growth, consistent increases in non-interest revenue and continued expansion in high-growth markets contributed to record earnings for BOK Financial Corporation in 2002. The Tulsa-based financial services company reported net income of $150.4 million, a 29 percent increase over 2001 and an extension of the consistent income growth experienced since the company's inception 12 years ago. For the fourth quarter, net earnings were $38.8 million, up 29 percent from the same period of 2001. Diluted earnings per share rose to $2.48 for the year, up 27 percent from the previous year. For the fourth quarter, diluted earnings per share rose 26 percent, to 63 cents. BOK Financial adopted a new accounting standard in 2002 that discontinued amortization of goodwill. If the standard had been effective during 2001, net income that year would have been $122.9 million, translating to a 22 percent increase in net income for 2002. "The company's performance in 2002 continues to validate our strategy of leveraging our market leadership in Oklahoma to expand in Texas and other high growth markets," said Stan Lybarger, the company's president and chief executive officer. "Our talented employees demonstrated once again the value of delivering nationally competitive products with community bank service." Page 2-BOKF 2002 Earnings Total revenue for 2002 rose 18 percent over the previous year. Net interest revenue, fee and commission revenue and net gains on securities and derivatives all contributed to the revenue growth. Net interest revenue was up 12 percent for the year due to growth in earning assets. Despite a soft economy, total loans grew 10 percent and deposits grew 18 percent, contributing to the growth in net interest revenue. Fee and commission revenue also rose 12 percent. The increase in fee and commission revenue was led by year-over-year increases in service charges and fees on deposit accounts (32 percent), brokerage and trading revenue (24 percent) and transaction card revenue (20 percent). Checking account overdraft protection contributed to growth in revenue from service charges and fees on deposit accounts while higher trading volume was a key factor in higher revenue from brokerage and trading activities. The continued growth in debit card use and the addition of new financial institution clients contributed to the increase in transaction card revenue. "We again demonstrated the value of our fee revenue sources that supplied 41 percent of our combined net interest and fee revenue base, which remains ahead of our peer group," Lybarger said. "A diverse revenue base from products and services that generate fees and commissions continues to contribute to consistent income growth through economic cycles." Overall, BOK Financial recognized gains on derivatives and sales of securities of $65 million, up $38 million from 2001. Of the total gains, $26 million represented gains associated with the mortgage servicing rights (MSR) hedge program. The company maintains a portfolio of securities as an economic hedge of its MSR assets in addition to securities it holds for investment and liquidity purposes. The $26 million gain from the MSR hedging strategy partially offset the $46 million provision for impairment of MSR taken in 2002 as mortgage rates hit historic lows. "The importance of our hedging strategy is evident, and if rates rise as the economy strengthens, we expect mortgage servicing valuations to rise," Lybarger said. Page 3-BOKF 2002 Earnings Net gains on the sale of other available-for-sale securities were $33 million compared to net gains of $18 million in 2001. BOK Financial followed its strategy of managing for total return during 2002. Mortgage-backed securities were sold to reduce the level of prepayment risk in the low interest rate environment. Operating expenses increased 15 percent to $426 million for the full year 2002. Excluding the provision for impairment and amortization of MSR, operating expenses were up only 4 percent. Both the impairment and amortization were extraordinarily high during 2002 as a result of record-high mortgage loan refinance activity. Data processing and communications expenses rose 18 percent for the year due to an increase in overall transaction volumes. Personnel expenses were up 12 percent for the year due to increased compensation rates and staffing and growth in incentive compensation. Total assets rose 9 percent to $12.2 billion. Loans grew to $6.9 billion during 2002. BOK Financial's Bank of Oklahoma subsidiary opened a Denver loan production office last January that posted $65 million in loans outstanding by year-end. The acquisition of Houston-based Bank of Tanglewood in October added $132 million to the loan portfolio. Overall, commercial loans grew 9 percent, commercial real estate loans 7 percent and residential mortgage loans 22 percent. "The acquisition of Bank of Tanglewood in Houston and the opening of our Denver loan production office contributed to growth in commercial lending in a soft economy," Lybarger said. "Our Denver office demonstrated once again the company's ability to leverage our strengths to target growth opportunities in neighboring states. We believe our position in middle market lending, private banking and trust services will continue to give us competitive advantages in growing markets." The quality of the loan portfolio continued to be evident. Nonperforming assets totaled $57 million or 0.84 percent of period-end loans at December 31, 2002 compared with $51 million or 0.83 percent of period end loans for the previous year end. The 2002 year-end allowance for loan losses was $116 million or 1.72 percent of period end loans and 233 percent of nonperforming loans. Net charge-offs to average loans declined to 0.33 percent for the year from 0.35 percent for the previous year. Page 4-BOKF 2002 Earnings Total deposits grew 18 percent to $8.1 billion during 2002. The increase included a $604 million growth in interest-bearing transaction deposits and $447 million in time deposits. The growth in deposits enabled BOK Financial to reduce its borrowed funds by $198 million and funded asset growth.
