Q

Coefficient of Variance

A

Coefficient of Variation is a way to compare the relative variation of two or more securities. The security with the lowest CV should be chosen.

Standard Deviation divided by the mean (average). All other risk related formulas have risk (SD or Beta) measurment in the denominator and this forfula (Coefficient of Variation) has it in the numerator and has the retuns in the denominator.

CV = SD / Mean

Q

Valuation of Real Estate?

A

Property Value = NOI / Cap Rate

To get NOI, you have to Add all Operating Income to get Gross Operating Income (rent + laundry, etc.).

Then apply the Vacancy rate (usually about 7%, so you will multiply by 93% to get the Operating Income)

Then you will subtract all the costs like property taxes, property insurance, property management, utilities, administration, repairs, maintenance, etc. (No not include Financing Costs or Depreciation). This number will give you your NOI.

Q

Growth Rate

A

This is used in the Discount Dividend Model

g = ROE x RR -or- ROE = g / RR

g = growth rate

ROE = Return on Equity (ROE is calculated by net income / shareholders equity)

RR = Retained Rate of Earnings => the remaining percentage is the Dividend Payout Rate, so if the RR = 80%, then the company paid 20% in Dividends.

RR = To calculate Divedend payout ratio => take Dividend / EPS = Payout then take (1-payout ratio ) to get Retained Earnings.

EPS = Divide current dividend by the dividend payout ratio (expressed as a decimal)

P/E = Divide price per share by the earnings per share

Q

DDM Formula for Non-Constant Rates of Growth?

A

Earnings and dividends per share are expected to grow at a rate of 18% over the next three years, and a constant rate of 6% thereafter. The last dividend was $1.15. The required return is 12%. What is the price of the stock today? This is done in 3 steps.

Step 1: What is the dollar amount of the dividend at the end of the each of the first three years?

Year 1: 1.15 x 1.18 = 1.3570

Year 2: 1.3570 x 1.18 = 1.6013

Year 3: 1.6013 x 1.18 = 1.8895

Step 2: What is the value of the stock at the end of Year 3 based on the dividend at the end of Year 4? Use Constant Growth Formula here.

[1.8895*(1.06) / 0.12-0.06] = 33.380

Step 3: What is the discounted value today of the stock price and the dividend at the end of Year 3 and each of the dividends for years 1 and 2?

Use calculator and solve for NPV as an irregular cash flow:

Q

How do I calculate the Price of when a Margin Call will occur?

Question:

An investor wants to buy 100 shares of a stock on margin. The stock is selling for $40 per share. The initial margin is 55% and the maintenance margin is 35%. Assuming she can purchase the stock at the current market price, at what price will a margin call occur?

A

The formula is [(1 − initial margin) / (1 − maintenance margin)] × price of stock = margin call price.

Answer:

the formula is [(1 − .55) / (1 − .35)] × 40 = 27.69

Q

HO - Property Insurance calculation when underinsured?

A

[(insurance carried / insurance required) x loss] - deductible = maximum amount of recovery

* Coinsurance requirement is usually 80% of replacement cost. This is primarily a concern in the event of a partial loss.

Ex: Question

Andrew purchased an automotive service station seven years ago for $500,000. The building’s current replacement value is $900,000. Andrew originally insured the building for its replacement cost of $500,000 and has not increased the coverage. His policy has an 80% coinsurance clause and a $5,000 deductible. Last week a fire caused $200,000 of damage.

Payment = ((Amount of insurance owned/Amount of insurance required) × Loss) - Deductible

Amount of insurance required = $900,000 × .8 = $$720,000

(($500,000/$720,000) × $200,000) − $5,000 = $133,889

Q

SE Tax Calculation and Contribution to a SEP

A

EX: Client net profit of $130,000

SS Wage Base is $127,200

What is max contribution to a SEP for owner?

STEP 1: CALCULATE SE SUBJECT TO TAXES: Schedule C Net Income of $130,000. Subtract 7.65% of ER FICA Tax from net income or multiply it by .9235 to get ($130,000 x .9235 = $120,055)

STEP 2: CALCULATE SE TAX: Multiply $120,055 by ER + EE FICA of 15.3% for a SE Tax of $18,368.

STEP 3: BUSINESS PROFIT: $130,000

STEP 4: LESS INCOME TAX DEDUCTION ALLOWED (1/2 of SE Tax): 1/2 of SE Tax is $18,368 / 2 = $9,184

STEP 5: NET EARNINGS: $130,000 - $9,184 = $120,816

STEP 6: SEP CONTRIBUTION: Owner can only contribute 20% of $120,816 = $24,163

Q

How to calculate QP contributions for a SP when net income is over SSA limit of $127,200.

If contribute 25% to EE’s then contribute (0.25/1.25 = 0.20)

If contribute 20% to EE’s then contribute (0.20/1.20 = 0.1667)

A

STEP 1: To calculate the self-employment tax, subtract 7.65% or multiply by 0.9235 from her net earnings ($180,000 - $13,770 = $166,230)

STEP 2: Then subtract the 2017 wage base of $127,200 to calculate the remaining dollars ($166,230 - $127,200 = $39,030) that are subject only to the 2.9% Medicare rate.

STEP 3: Multiply the wage base by 15.3% for a total of $19,462 and add that to the Medicare amount ($39,030 × 2.9%) of $1,132 for a total of $20,594.

STEP 4: One-half of the self-employment tax, or $10,297 is deductible as an adjustment to income.

STEP 5: Reduce the net profit of $180,000 by $10,297 (=$169,703) and we then multiply that by Cheryl’s contribution percentage.

STEP 6: Since she contributes 20% into the money purchase plan for her employees, she would contribute 16.67% (16.67% is arrived at by taking .20/1.20 = .1667) the contribution for Cheryl would be 16.67% × $169,703 = $28,289.

Q

What is the charitable deduction when using a Charitable Lead Annuity Trust (CLAT)?

A

The charitable deduction is the PV of the income interest. The IRS will give a Table B giving a factor to use to compute the PV of income interest.

Annuity Payout x Table B factor = PV of charitable deduction

See Q below:

Henry’s will directed that $300,000 be placed in a charitable lead annuity trust (CLAT), with $40,000 per year payable for 10 years to a qualified charity, with the remainder being paid equally to his two children. The applicable interest rate for the month of Henry’s death was 8.0% and the annuity factor is 6.7101. Payments of income are to be made annually, starting one year from Henry’s death. How much of this bequest, if any, qualifies for the charitable deduction?

Answer:

Only the present value of the income interest qualifies for the charitable deduction. IRS Table B must be used to compute the present value of this income interest since the trust is to last for a term certain. The appropriate annuity factor from Table B is 6.7101, which, when multiplied by the annuity payment of $40,000, yields a present value of $268,404.
