Question 3 [40%]

The Seri Bayu Heights apartment complex uses the following system for processing security deposits and rental payments:

When a tenant signs a lease and pays a security deposit, the manager creates a data sheet on the tenant which includes name, apartment number, phone number, permanent address (if other than the new apartment), amount of rent, amount of security deposit, move-in date, length of lease, pet deposit (if any), and person to notify in case of an emergency. The manager sends this form to the data processing (DP)department to be entered on-line into the accounts receivable (A/R) file. The manager also gives a receipt and a copy of the lease to the tenant.

A card is created with the tenant's name, apartment number, amount due, and amount paid from the A/R file and send back to the manager. The manager then attaches the security deposit cheque to the card.

**This card and cheque are sent to A/R department where daily deposits are batched and the cheques are deposited into the proper bank account. The cards that came in with the cheques are sorted by name alphabetically and will be entered into a computer. The cards are read, a daily cash report is generated, and the A/R file is updated. At the end of the month, new cards are generated for each tenant. As the tenants pay the rent due, a card is pulled for each tenant and attached to the cheque or money order payment**. The same procedure (from ** to **) is followed for the rent payment as well as the security deposit.

On the tenth day of the month, a delinquent list will be generated by the A/R department from the A/R file. The list includes all tenants who have some balance due on their account. The manager sends a notice to each delinquent tenant along with an overdue charge.
