A local credit union offers two types of savings accounts, regular rate and split rate . The regular rate account pays dividends on the account balance at the end of each quarter – funds withdrawn during the quarter earn no dividends. There is no minimum balance on the regular rate account. Regular rate accounts may be insured. Insured accounts pay 5.75 percent annual interest. Uninsured regular rate accounts pay 6.00 percent annual interest. For split rate accounts, dividends are paid monthly on the average daily balance for the month. Daily balances go up and down according to deposits and withdrawals. The average daily balance is determined by adding each day’s closing balance and dividing this sum by the number of days in the month. If the average daily balance is less than $25, then no dividend is paid. Otherwise, if the average daily balance is $25 or more,6 percent per annum is paid on the first $500, 6.5 percent on the next $1,500 , and 7 percent on funds over $2,000. There is no insurance on split rate accounts. 1. Describe the rules for creating a context diagram. 2. Make a basic list of dos and don’ts when developing DFDs. 3.
