Q

The Present Value of a Single Cash Flow

A

We will first look at discounting a single cash flow or amount. The cash flow can be discounted back to a present value by using a discount rate that accounts for the factors mentioned above (present consumption preference, risk, and inflation). Conversely, cash flows in the present can be compounded to arrive at an expected future cash flow.

The present value of a single cash flow can be written as follows:

Q

Present Value of a Perpetuity

A

Sometimes annuities last forever – or so we pretend. What is the value of payments that are received indefinitely, like proverbial AT&T dividends? On first reflection, you might think that a perpetual annuity would be infinite. But remember that $1 paid in 10 years is worth only pennies today (assuming normal inflation and the inherent time value of money) and $1 paid in 100 years is not worth picking up from the sidewalk.

PV
the present value (or initial principal)
Pymtn- the payment made at the end of each of an infinite number of periods
i- the discount rate for each period (assumed equal throughout)

The present value of a perpetual stream of future payments eventually reaches a limit. And, it turns out that the formula for an infinite series of equal payments, discounted by a constant discount rate, is simplicity itself:

Q

Continuous Compounding and Future Values

A

The future value (FV) of an annuity with continuous compounding formula is used to calculate the ending balance on a series of periodic payments that are compounded continuously. Understanding the future value of annuity with continuous compounding formula requires the understanding of two specific financial and mathematical concepts, which are future value of an annuity and continuous compounding.

Q

Bank Discount Yield

A

Discount yield is a measure of a bond’s percentage return. Discount yield is most frequently used to calculate the yield on short-term bonds and treasury bills sold at a discount. This yield calculation uses a 30-day month and 360-day year to simplify calculations. Discount yield is calculated by the following formula: Discount Yield = [(par value - purchase price)/par value] * [360/days to maturity]

Q

Holding Period Yield

A

The total return received from holding an asset or portfolio of assets. Holding period return/yield is calculated as the sum of all income and capital growth divided by the value at the beginning of the period being measured. Holding period return is a very basic way to measure how much return you have obtained on a particular investment. This calculation is on a per-dollar-invested basis, rather than a time basis, which makes it difficult to compare returns on different investments with different time frames. When making comparisons such as this, the annualized calculation shown above should be used.

Q

Effective Annual Yield

A

The yield after taking into account the consequences of compounding. It is computed as [1 + (stated interest/n)]n - 1; where n is the number of payments within the year. For instance, a bond’s return is 5% and is to be paid semi-annually, thus, the effective annual yield is calculated as: [1 + (.05/2)2 - 1 = 5.062%.

Q

Money Market Yield

A

The interest rate earned by investing in securities with high liquidity and maturities of less than one year such as negotiable certificates of deposit, U.S. Treasury bills and municipal notes. Money market yield is calculated by taking the holding period yield and multiplying it by a 360-day bank year divided by days to maturity. It can also be calculated using bank discount yield. Also known as “CD-equivalent yield”. To earn a money market yield, it is necessary to have a money market account. Banks offer money market accounts because they need to borrow funds on a short-term basis to meet reserve requires and to participate in interbank lending. The money market yield will be lower than the yield on stocks and bonds because of the low risk associated with money market investments.

Q

Bond Equalent Yield

A

A calculation for restating semi-annual, quarterly, or monthly discount-bond or note yields into an annual yield. For a fixed income security with a par value of $1000, the calculation is as follows: The BEY allows fixed-income securities whose payments are not annual to be compared with securities with annual yields. The BEY is the yield that is quoted in newspapers. Alternatively, if the semi-annual or quarterly yield to maturity of a bond is known, the APR calculation may be used.

Net income after tax under FIFO will be greater than LIFO net income after tax by:
Change in LIFO Reserve x (1 - Tax rate)
159
When converting from LIFO to FIFO assuming rising prices:
``` Equity (retained earnings) increase by: LIFO Reserve x (1 - Tax rate) Liabilities (deferred taxes) increase by: LIFO Reserve x (Tax rate) Current assets (inventory) increase by: LIFO Reserve ```
160
Net Present Value (NPV)
Net Present Value (NPV)= (CFt / (1+r) ^ t ) - outlay ``` CFt = after-tax cash flow at time, t. r = required rate of return for the investment. This is the firm’s cost of capital adjusted for the risk inherent in the project. Outlay = investment cash outflow at t = 0. ```
161
Net Present Value (NPV)
Net Present Value (NPV)= (CFt / (1+r) ^ t ) - outlay ``` CFt = after-tax cash flow at time, t. r = required rate of return for the investment. This is the firm’s cost of capital adjusted for the risk inherent in the project. Outlay = investment cash outflow at t = 0. ```
162
Average Accounting Rate of Return (AAR)
AAR = Average net income / Average book value
163
Profitability Index
PI = PV of future cash flows / Initial investment Initial investment = 1 + NPV/ Initial investment Initial investment
164
Weighted Average Cost of Capital
WAAC= (wd)(rd)(1-t) + (wp)(rp)+(wc)(rc) Where: wd = Proportion of debt that the company uses when it raises new funds rd =Before-tax marginal cost of debt t = Company’s marginal tax rate wp = Proportion of preferred stock that the company uses when it raises new funds rp = Marginal cost of preferred stock we = Proportion of equity that the company uses when it raises new funds re = Marginal cost of equity
165
Weighted Average Cost of Capital
WAAC= (wd)(rd)(1-t) + (wp)(rp)+(wc)(rc) Where: wd = Proportion of debt that the company uses when it raises new funds rd =Before-tax marginal cost of debt t = Company’s marginal tax rate wp = Proportion of preferred stock that the company uses when it raises new funds rp = Marginal cost of preferred stock we = Proportion of equity that the company uses when it raises new funds re = Marginal cost of equity
166
Valuation of Bonds
Po= [ PMT/ (1 + rd/2) ^2 ) + FV/ (1 + rd/2) ^ n where: P0 = current market price of the bond. PMTt = interest payment in period t. rd = yield to maturity on BEY basis. n = number of periods remaining to maturity. FV = Par or maturity value of the bond
167
Dividend Discount Model
Po= D1 / re- g where: P0 = current market value of the security. D1= next year’s dividend. re = required rate of return on common equity. g = the firm’s expected constant growth rate of dividends.
168
Capital Asset Pricing Model
re = RF + Bi[E(RM) - RF]
169
Sustainable Growth Rate
g = ( 1 - D/EPS) x (ROE) | Where (1 - (D/EPS)) = Earnings retention rate
170
Bond Yield plus Risk Premium Approach
re= rd + risk premium
171
Degree of Operating Leverage
DOL = Q x (P – V) / Q x (P – V) – F ``` where: Q = Number of units sold P = Price per unit V = Variable operating cost per unit F = Fixed operating cost Q x (P – V) = Contribution margin (the amount that units sold contribute to covering fixed costs) (P – V) = Contribution margin per unit ```
172
Degree of Operating Leverage
DOL = Q x (P – V) / Q x (P – V) – F ``` where: Q = Number of units sold P = Price per unit V = Variable operating cost per unit F = Fixed operating cost Q x (P – V) = Contribution margin (the amount that units sold contribute to covering fixed costs) (P – V) = Contribution margin per unit ```
173
DFL
[Q(P – V) – F](1 – t) / [Q(P – V) – F – C](1 – t) ``` where: Q = Number of units sold P = Price per unit V = Variable operating cost per unit F = Fixed operating cost C = Fixed financial cost t = Tax rate ```
174
Degree of Total Leverage
DTL = Percentage change in net income / Percentage change in the number of units sold
175
Degree of Total Leverage
DTL = Percentage change in net income / Percentage change in the number of units sold
176
DTL
DTL = DOL x DFL
177
DTL
DTL = Q x (P – V) / [Q(P – V) – F – C] ``` where: Q = Number of units produced and sold P = Price per unit V = Variable operating cost per unit F = Fixed operating cost C = Fixed financial cost ```
178
The breakeven number of units can be calculated as:
The breakeven number of units can be calculated as: | QBE =F + C / P – V

Number of days of receiveables
Number of days of receiveables= Accounts receivable/ average day s sales on credit = accounts receivebale/ (sales on credit / 365)
185
Number of days of receiveables
Number of days of receiveables= Accounts receivable/ average day s sales on credit = accounts receivebale/ (sales on credit / 365)
186
number of days of inventory
number of days of inventory= inventory/ average days cost of goods sold = inventory/ (cost of goods sold/ 365)
187
number of days of inventory
number of days of inventory= inventory/ average days cost of goods sold = inventory/ (cost of goods sold/ 365)
188
Payables Turnover
Payables Turnover= Purchases/ Average Trade Payables
189
Purchases
Purchases = Ending inventory + COGS - Beginning inventory
190
Purchases
Purchases = Ending inventory + COGS - Beginning inventory
191
Operating Cycle
Operating Cycle= Number of Days of Inventory + Number of days of receiveables
192
Net Operating Cycle
Net Operating Cycle= Number of days of inventory + number of days of receiveable = Number of days of payables
193
% Discount
% Discount = Face value - Price / Price
194
