The U.S. banking industry is particularly affected by the year 2000 problem because nearly every aspect of the business is dependent on computer systems for processing transactions and providing information. Technology is an integral part of the banks' interconnected information systems, where they exchange data daily with their customers, correspondents, vendors, other financial institutions, clearing houses, and corporate borrowers. Therefore, any malfunctions caused by the century date change could have an impact on a bank's ability to meet its obligations. Or, malfunctions could have an impact on the ability of others to meet their obligations to the bank. Some examples of bank systems where year 2000 problems may emerge include:
Lending systems: To calculate interest payments, due dates, and past due amounts;
Investment systems: To calculate accretions, amortization, and yields;
Deposit systems: To calculate interest payments, overdrafts, and other fees;
Accounting systems: To calculate accruals, depreciations; income and expenses;
Fiduciary systems: To perform portfolio analysis, stock transfers; and calculate dividends and maturity dates;
Management information systems: To integrate information by time period (p. 3).
