Bank of Oklahoma Financial Realizes Revenue Enhancement and Cost Reduction Through Carreker-Antinori's

(Dallas, TX April 23, 1999) - At the Bank Administration Institute’s (BAI) Transaction Processing Conference in Miami Beach, Paul "Mike" Elvir, EVP, Bank of Oklahoma (NADAQ:BOKF) and Mike Inman, Managing Principal, Carreker-Antinori, Inc. (NASDAQ:CANI) presented the results of a recent consulting engagement Carreker-Antinori performed for the bank. By combining new technologies and best practices, Carreker-Antinori was able to reengineer Bank of Oklahoma (BOK) operations, resulting in new revenues and reduced operating costs for the bank.

"What this ultimately means for us is that Carreker-Antinori’s services have created an opportunity to improve our efficiency ratio and enhance shareholder value," says Elvir. After extensively evaluating the bank’s priorities, processes and market presence, Carreker-Antinori was able to identify revenue enhancements utilizing market segmentation, and by re-deploying non-earning assets and optimizing BOK’s reserve and cash disposition.

Commenting on how BOK enhanced revenue through market segmentation and cost reduction, Inman says, "In order for the bank and Carreker-Antinori to fully understand BOK’s market segmentation potential, we asked them to engage in a step-by-step process whereby components of price, elements of sensitivity and untapped opportunities were identified. For example, the first step was to gain insight into customer needs and their price sensitivities by defining key customer float and earnings credit sensitivities, creating and account analysis database, analyzing the customer mix and interviewing the bank’s product manager sales force."

In order to reduce BOK’s non-earning assets, Carreker-Antinori assisted the bank in reducing its reserveable liabilities and cash inventories. Carreker-Antinori identified opportunities to reduce the bank’s reserve requirements below cash levels, creating an excess cash position. To help the bank reduce this excess cash, Carreker-Antinori used a two-step process. The first involved a review of the bank’s branches, vaults and ATMs, which resulted in the identification of tactical cash reductions. The expected cash reductions are estimated at 10-15 percent. However, without a tool for ongoing management of cash inventories, cash reductions are likely non-sustainable. Therefore, step two involved the implementation of the CashTrackerÔ system, an automated cash tracking tool that provides cash consumption reports/graphs and target cash inventory levels. It is expected that BOK will sustain a 25+ percent cash reduction.

"We are pleased with Carreker-Antinori’s recommendations and expect to significantly enhance the bank’s opportunity for revenue growth and cost reduction," says Elvir. "Going forward, our competitive challenges, as well as merger and acquisition opportunities will only increase, resulting in a continued focus on the bank’s efficiency ratio. We look forward to partnering with Carreker-Antinori to assist us in identifying and leveraging these future endeavors."
