Assume a security matures for $10,000 five years and seven months from today. Assume also that the security makes semiannual payments with the final semiannual payment also occurring five years and seven months from today. The next payment will equal $100 and subsequent payments will fall by 2% each. Finally, assume that the APR on investments with comparable risk equals 3.5% per year with monthly compounding. 

What is the most you should pay for this security today?
