An individual deposits an equal amount in a bank saving account every year for 10 years. He then withdraws this money in semiannual amounts of KD1000 starting from the end of the first half of year 11 until the end of year 15. The nominal interest rate for the first 5 years is 5% compounded annually. For year 6 until year 15, the nominal interest rate is 4% compounded semiannually. Calculate the annual equal amounts of deposits.
