Specifies the principal amount of the loan. Specifies the size and timing of the cash flows:
In dollar terms (fixed-rate borrowing) As a formula (adjustable-rate borrowing)

5.2 How to Value Bonds
Identify the size and timing of cash flows.
Discount at the correct discount rate.
If you know the price of a bond and the size and timing of cash flows, the yield to maturity(YTM) is the discount rate. Yield to maturity (YTM) is bond jargon for the discount rate that equates the price of a bond with the discounted value of its coupons and face (par) value. In other words, present value = price when r =YTM. The yield to maturity represents the current market interest rate for a bond.

Example of pure discount bonds:
What is the price of a 25-year, pure discount bond that pays $50 at maturity if the current yield-to maturity is 8 percent?
The Par Value of the bond is $1,000. Coupon payments are made semi-annually (June 30 and December 31 for this particular bond). Since the coupon rate is 6 3/8 the payment is $31.875. On January 1, 2005 the size and timing of cash flows are:
