3-3 $10,000 today Obviously, $10,000 today. TIME VALUE TO MONEY You already recognize that there is TIME VALUE TO MONEY!! The Interest Rate $10,000 today $10,000 in 5 years Which would you prefer -- $10,000 today or $10,000 in 5 years?

3-4 Main Idea about Time Value of Money uMuMoney that the firm or an individual has in its possession today is more valuable than future payments because the money it now can be invested and earn positive returns. A bird in hand worth more than two in the bush

3-5 Why Money has Time Value? The existence of interest rates in the economy results in money with its time value. Sacrificing present ownership requires possibility of having more future ownership. Inflation in economy is one of the major cause. Risk or uncertainty of favorable outcome.

3-6 TIME INTEREST TIME allows you the opportunity to postpone consumption and earn INTEREST. Why TIME? TIME Why is TIME such an important element in your decision?

3-7 Major Importance of Time Valueof Money It is required for accounting accuracy for certain transactions such as loan amortization, lease payments, and bond interest. In order to design systems that optimize the firms cash flows. For better planning about cash collections and disbursements in a way that will enable the firm to get the greatest value from its money.

3-8 Major Importance of Time Value of Money Funding for new programs, products, and projects can be justified financially using time –value-of- money techniques. Investments in new equipment, in inventory, and in production quantities are affected by time-value- of-money techniques.

3-9 Types of Interest u Compound Interest Interest paid (earned) on any previous interest earned, as well as on the principal borrowed (lent). u Simple Interest Interest paid (earned) on only the original amount, or principal, borrowed (lent).

3-10 Simple Interest Formula Formula FormulaSI = P 0 (i)(n) SI:Simple Interest P 0 :Deposit today (t=0) i:Interest Rate per Period n:Number of Time Periods

3-11 $140 u SI = P 0 (i)(n) = $1,000(.07)(2) = $140 Simple Interest Example u Assume that you deposit $1,000 in an account earning 7% simple interest for 2 years. What is the accumulated interest at the end of the 2nd year?

3-12 FV $1,140 FV = P 0 + SI = $1,000 + $140 = $1,140 u Future Value u Future Value is the value at some future time of a present amount of money, or a series of payments, evaluated at a given interest rate. Simple Interest (FV) Future Value FV u What is the Future Value (FV) of the deposit?

3-13 The Present Value is simply the $1,000 you originally deposited. That is the value today! u Present Value u Present Value is the current value of a future amount of money, or a series of payments, evaluated at a given interest rate. Simple Interest (PV) Present Value PV u What is the Present Value (PV) of the previous problem?

3-14 FV 1 P 0 $1,000 $1,070 FV 1 = P 0 (1+i) 1 = $1,000 (1.07) = $1,070 Compound Interest You earned $70 interest on your $1,000 deposit over the first year. This is the same amount of interest you would earn under simple interest. Future Value Single Deposit (Formula)

3-15 FV 1 P 0 $1,000 $1,070 FV 1 = P 0 (1+i) 1 = $1,000 (1.07) = $1,070 FV 2 P 0 $1,000 P 0 $1,000 $1, FV 2 = FV 1 (1+i) 1 = P 0 (1+i)(1+i) = $1,000(1.07)(1.07) = P 0 (1+i) 2 = $1,000(1.07) 2 = $1, $4.90 You earned an EXTRA $4.90 in Year 2 with compound over simple interest.

3-31 Types of Annuities u Ordinary Annuity u Ordinary Annuity: Payments or receipts occur at the end of each period. u Annuity Due u Annuity Due: Payments or receipts occur at the beginning of each period. u An Annuity u An Annuity represents a series of equal payments (or receipts) occurring over a specified number of equidistant periods.

3-39 Hint on Annuity Valuation beginning end The present value of an ordinary annuity can be viewed as occurring at the beginning of the first cash flow period, whereas the future value of an annuity due can be viewed as occurring at the end of the first cash flow period.

3-40 Example for Annuity (cont.) Example-5: (P. 166) Cute Baby Company, a small producer of plastic toys, wants to determine the most it should pay to purchase a particular ordinary annuity. Find the present value if the annuity consists of cash flows of $700 at the end of each year for 5 years. The firm requires the annuity to provide a minimum return of 8%.

3-41 Perpetuity # A stream of equal payments expected to continue forever. Formula: Payment PMT PV (Perpetuity) = = Interest Rate i The present value of this special type of annuity will be required when we value perpetual bonds and preferred stock.
