You lend a friend $, which your friend will repay in equal annual end-of-year payments of $, with the first payment to be r

Vadim26 [7]

Answer: 18%

Explanation:

The payments that your friend will make are an annuity as they are constant. This means that the loan amount of $15,000 is the present value of the annuity.

To find the rate of return, use the factor tables.

Present value of annuity = Annuity * Present value interest factor of annuity, 14 years, ?%

15,000 = 3,000 * Present value interest factor of annuity, 14 years, ?%

Present value interest factor of annuity, 14 years, ?% = 15,000 / 3,000

Present value interest factor of annuity, 14 years, ?% = 5.0

Go to the present value of annuity factor table and find out what interest rate intersects with 14 periods such that the factor is 5.0.

That rate is 18%.

Rate of return is therefore 18%.

Glavine Company issues 6,000 shares of its $5 par value common stock having a fair value of $25 per share and 9,000 shares of it

almond37 [142]

Answer:

Market value of common stocks (6,000 x $25) = 150,000

Market value of preferred stocks (9,000 x $20) = 180,000

Market value of the company 330,000

Proceeds allocated to common stocks

= $150,000/$330,000 x $312,000

= $141,818

The correct answer is B

Explanation:

The market value of the company is the aggregate of market value of common stocks and market value of preferred stocks.The market value of each stock is equal to number of each stock outstanding multiplied by market price per share. Thus, the proceeds allocated to common stock equals the market value of equity divided by market value of the company multiplied by the lump sum.

A stock has an expected return of 11 percent, its beta is 1.20, and the risk-free rate is 4.4 percent. What must the expected re

Drupady [299]

Answer:

Expected market return = 9.8%

Explanation:

The expected return on the market can be worked out using the Capital Asset Pricing Model.

<em>The capital asset pricing model is a risk-based model. Here, the return on equity is dependent on the level of reaction of the the equity to changes in the return on a market portfolio. These changes are captured as systematic risk. The magnitude by which a stock is affected by systematic risk is measured by beta. </em>

Under CAPM, Ke= Rf + β(Rm-Rf)

Rf-risk-free rate (treasury bill rate)- 4.4%

β= Beta - 1.20

Rm= Return on market.- ?

Applying this model, we have

11%= 4.4%+ (R-4.4%)×1.20

0.11-0.044= 1.20×(R-0.04)

0.07 = 1.20R-0.048

Collect like terms

0.07+0.048 = 1.2R

Divide both sides by 1.20

R= (0.07+0.048)/1.20

R=9.83%

Expected market return = 9.8%
