The certificates for all long-term investments are kept in a safe deposit box at the local bank; only the president of Oakdale has access to this box. An inventory of this box was made, and all certificates were accounted for. Certificates for short-term investment are kept in a locked metal box in the accounting office. Other documents, such as long-term contracts and legal agreements, are also kept in this box. There are three keys to the box, held by the president, treasurer, and the accounting manager, The accounting manager’s key is available to all accounting personnel, should they require documents kept in this box. Certificates of investments may take up to four weeks to receive after the purchase of the investment. An electronic inventory list is kept perpetually.

The president, treasurer, and accounting manager all have passwords to access and update this inventory list. The accounting manager’s password is known by two of the accounting supervisors in case the inventory list needs to be updated when the accounting manager is not available. Documentation for two of the current short-term investments could not be located in this box the accounting manager explained that some of the investments are for such short periods of time that formal documentation is not always provided by the broker.
