Answer:
convexity = 37.6306
Explanation:
given data:
maturity time = 7 years
yield to maturity (y) = 8% = 0.08
coupon bond = 6%
price= $89.59 ( gotten from the summation of pv(cf) from the table attached below )
t = time
convexity can be found using this formula
[tex]= \frac{1}{p(1+y)^2} * summation of (t +t^2) * pv(cf)[/tex]
= [tex]\frac{1}{89.59*(1.08)^2} * 3932.310[/tex] = 37.6306
Valentine is a producer in a monopoly industry. Her demand curve and total cost curve are given as follows: Q = 160 - 4P ; TC = 4Q. The price of her product will be:
Answer: b) $22
Explanation:
A Monopoly will maximise output where Marginal Revenue equals Marginal cost.
Marginal revenue (MR) is the differential of Total revenue.
= (dTR/dQ ) 40Q - 0.25Q^2
= 40 - 0.5Q
Marginal Cost is the differential of Total cost.
= dTC/dQ
= 4
MR = MC
40 - 0.5Q = 4
36 = 0.5Q
Q = 72 units is the maximising quantity.
Price
Q = 160 - 4P
72 = 160 - 4P
4P = 160 -72
4P = 88
P = $22

West Corp. issued 14-year bonds 2 years ago at a coupon rate of 9.8 percent. The bonds make semiannual payments. If these bonds currently sell for 103 percent of par value, what is the YTM?
Answer:
The answer is 9.38%
Explanation:
This is a semiannual paying coupon. And it means West Corp pays interest twice a year.
N(Number of periods) = 24 periods ( [14years - 2 years ago] x 2)
I/Y(Yield to maturity) = ?
PV(present value or market price) = $1,030 ( 103% x $1,000)
PMT( coupon payment) = $49 ( [9.8 percent÷ 2] x $1,000)
FV( Future value or par value) = $1,000.
We are using a Financial calculator for this.
N= 24; PV = 1.030; PMT = 49; FV= $1,000; CPT I/Y= 4.69
Therefore, the Yield-to-maturity of the bond for annual is 9.38% (4.69% x 2)

17,000 units of product A should be processed further.
Explanation:
Preparation of analysis that shows whether 17,000 units of Product A should be processed further or not.
Sell Process further
Sales $490,000 $1,228,000
Relevant costs
Additional cost to process further $300,000
Total relevant costs $300,000
Income (loss) $490,000 $928,000
Calculation for sales after processing further
Sales after processing further = (5,400 x $104) + (11,900 x $56)
Sales after processing further= $561,600 + $666,400
Sales after processing further= $1,228,000
Calculation for Net incremental income
Net incremental income = $928,000 - $490,000
Net incremental income= $438,000
Therefore 17,000 units of product A should be processed further.
Company A is considering a merger with Company B. A has 43,000 shares outstanding at a market price of $32 a share. B has 12,800 shares outstanding priced at $44 a share. The merger is expected to create $5,400 of synergy. What will be the total value of the merged firm?
A) $568,600
B) $1,376,000
C) $446,073
D) $563,200
E) $1,381,400
Answer: $1381400
Explanation:
From the question, we are informed that Company A is considering a merger with Company B and that A has 43,000 shares outstanding at a market price of $32 a share while B has 12,800 shares outstanding priced at $44 a share and the merger is expected to create $5,400 of synergy.
The total value of the merged firm will be:
= (43,000 × $32) + (12,800 × $44) + $5,400 - $563,200
= $1,376,000 + $563,200 + $5,400 - $563,200
= $1,944,600 - $563,200
= $1,381,400

The choices do not provide any clue for further explanation. However, one can identify that the promise to assume a debt is a contract. For most business contracts to be enforceable, there is the need for the promise to be in writing. This provides a documented evidence which can be tendered in the court of law. It is a known adage that a short pen is greater than a long memory. So, exchange of promises or consideration is better done in writing form than orally.
Consider the following spreadsheet. The objective is to minimize the total cost of assigning jobs to machines. A job can be assigned to only one machine and a machine can be assigned only one job. All jobs must be assigned. Cells B3:F7 contain the assignment costs of jobs to machines. Cells B12:F16 contain the decision variables. a) What formula should be placed in cell I3
Available Options Are:
A. =SUM(G12:G16).
B. =SUMPRODUCT(B3:F7, B12:F16)
C. SUMPRODUCT(B3:F7, B12:F16).
D. =SUM(B12:F16)
Answer:
Option B. =SUMPRODUCT(B3:F7, B12:F16)
Explanation:
Here we need summation of two rows B3:F7 and B12:F16. The formula that we will use will be SUMPRODUCT. To calculate sum product in I3 we will edit equal sign first and then "SUMPRODUCT(,)". Then complete the rows that we want to add. Before the coma sign we will place the first row which is B3:F7 and after the coma sign we will place the second row which is B12:F16. In this way we would compute the summation of values present in both rows.
This means that only Option B is correct here.
Option A is not correct because it is the summation of cells present in a single column which doesn't include any cost item assigned. Hence it is incorrect as the formula must be the summation of 2 rows.
Option C is incorrect because it doesn't includes equal sign at the start.
Option D is incorrect because it is only the sum of a single row B12:F16, hence it is incorrect.

Hudson Corporation will pay a dividend of $5.00 per share next year. The company pledges to increase its dividend by 7.80 percent per year indefinitely.
If you require a return of 5.40 percent on your investment, how much will you pay for the company's stock today?
a. $150.86
b. $157.14
c. $163.43
d. $152.12
e. $36.72
Answer:
$157.14
Explanation:
Calculation for how much will you pay for the company's stock today
Using this formula
P0 = D1 / (Ke - g)
Where,
P0 = Price of Share
D1 = Current Dividend=$3.30
Ke = Cost of Equity=5.40%
g = growth rate=3.30%
Let plug in the formula
P0 = $3.30/ (5.40%-3.30%)
P0 = $3.30/0.021
P0= $157.14
Therefore the amount that you will pay for the company's stock today will be $157.14

In December Year 4, Mill Co. began including one coupon in each package of candy that it sells and offering a toy in exchange for $.30 and one coupon. The toys cost Mill $.80 each. Eventually, 70% of the coupons will be redeemed. During December, Mill sold 100,000 packages of candy and 15,000 coupons were redeemed. In its Year 4 income statement, what amount should Mill report as Premium Expense?
Answer:
$35,000
Explanation:
Sine Mill expects that 70% of the coupons will be redeemed, their premium expense should equal 70% x 100,000 packages x ($0.80 - $0.30) = $35,000
the journal entry to record the issuing of the discount coupons should be:
Dr Premium (or toy coupons, or marketing) expense 35,000
Cr Toy coupons liability 35,000
Since 15,000 were redeemed in December, the adjusting entry should be:
December 31, year 4
Dr Toy coupons liability 7,500
Cr Toys inventory 7,500
g. How does the equation for valuing a bond change if semiannual payments are made? Find the value of a 10-year, semiannual payment, 10% coupon bond if the nominal rd 13%. Ehrhardt, Michael C.. Corporate Finance: A Focused Approach (p. 236). Cengage Learning. Kindle Edition.
Answer:
$834.73
Explanation:
the market value of the bonds is calculated by adding the present value of its maturity value (face value) + the present value of its coupon payments. The discount rate will be the market rate instead of the coupon rate:
PV of face value = $1,000 / (1 + 6.5%)²⁰ = $283.80
PV of coupon payments = $50 x 11.01851 (PV annuity factor, 6.5%, 20 periods) = $550.93
the bond's market value = $283.80 + $550.93 = $834.73

Problem 16-4 Break-Even EBIT [LO1] Round Hammer is comparing two different capital structures: An all-equity plan (Plan I) and a levered plan (Plan II). Under Plan I, the company would have 195,000 shares of stock outstanding. Under Plan II, there would be 145,000 shares of stock outstanding and $2.9 million in debt outstanding. The interest rate on the debt is 7 percent, and there are no taxes. a. If EBIT is $475,000, what is the EPS for each plan? (Do not round intermediate calculations and round your answers to 2 decimal places, e.g., 32.16.) b. If EBIT is $725,000, what is the EPS for each plan? (Do not round intermediate calculations and round your answers to 2 decimal places, e.g., 32.16.) c. What is the break-even EBIT? (Do not round intermediate calculations. Enter your answer in dollars, not millions of dollars, e.g., 1,234,567.)
Answer:
a)
under plan I:
EBIT = $475,000
net income = $475,000
EPS = $475,000 / 195,000 stocks = $2.44
under plan II:
EBIT = $475,000
net income = $475,000 - ($2,900,000 x 7%) = $272,000
EPS = $272,000 / 145,000 stocks = $1.88
b)
under plan I:
EBIT = $725,000
net income = $725,000
EPS = $725,000 / 195,000 stocks = $3.72
under plan II:
EBIT = $725,000
net income = $725,000 - ($2,900,000 x 7%) = $522,000
EPS = $522,000 / 145,000 stocks = $3.60
c)
in thousands
EBIT / 195 = (EBIT - $203) / 145
145EBIT = 195EBIT - $39,585
50EBIT = $39,585
EBIT = $39,585 / 50 = $791.7 x 1,000 = $791,700
The current yield is defined as the annual interest on a bond divided by par value true or false?
Answer: False
Explanation:
The Current Yield is calculated by dividing the annual interest on a bond by the current price and not the par value. This way the current price of the bond is the one that matters.
The Current Yield is calculated based on the logic of what the investor can expect as returns for purchasing the bond at the current rate and then holding it for a year or less and so is not the return that can be expected if the bond is held till maturity.
How much total depreciation and amortization expense did Patnode record during 2015?
a. $10,000
b. $6,000
c. $3,000
d. $5,000
Answer:
d. $5,000
Explanation:
Patnode's information is missing, so I looked it up. I found the balance sheet for 2014 and 2015. Hope that it is the same question:
total depreciation expense for 2015 = change in accumulated depreciation (2015 - 2014) + change in accumulated amortization (2015 - 2014) = ($3,000 - $0) + ($3,000 - $1,000) = $3,000 + $2,000 = $5,000
A firm is producing 20 units with an average total cost of $25 and marginal cost of $15. If it were to increase production to 21 units, which of the following must occur?
a. Marginal cost would decrease.
b. Marginal cost would increase.
c. Average total cost would decrease.
d. Average total cost would increase.
Answer:
c. Average total cost would decrease.
Explanation:
At the time of more units produced by a firm for a valid reason like efficient labor, good quality tools of production etc so in this the average fixed cost is inbuilt also it is allocated to the large number of output units plus the variable cost is also decline
Therefore the average total will always decline as the level of production increased because the average total cost involves both the cost i.e. average fixed cost and the average variable cost
Hence, option C is correct
Which of the following are examples of variable cost?
(select 3 answers)
a. a radio ad
b. hourly employees
c. the yarn used to make a scarf
d. rent of an office space
e. the shampoo used to groom pets
f. internet services
Answer:
Which of the following are examples of variable cost?
hourly employees
Variable costs vary directly and proportionally to variations in the level or volume of business activity. Examples of variable costs include options (c), (d), and (e).
What is a variable cost?A variable cost is a corporate and business expense that varies in relation to the amount of product or service produced or sold.
Variable costs rise or fall in relation to a company's production or sales volume, rising as production increases and falling as production drops.
As a result, variable expenses include the yarn required to manufacture a scarf, the rent for office space, and the shampoo used to groom dogs.

Which of the following statements is CORRECT?
A) When firms are deciding on the size of stock splits--say whether to declare a 2-for-1 split or a 3-for-1 split, it is best to declare the smaller one, in this case the 2-for-1 split, because then the after-split price will be higher than if the 3-for-1 split had been used.
B) Back before the SEC was created in the 1930s, companies would declare reverse splits in order to boost their stock prices. However, this was determined to be a deceptive practice, and reverse splits are illegal today.
C) Stock splits create more administrative problems for investors than stock dividends, especially determining the tax basis of their shares when they decide to sell them, so today stock dividends are used far more often than stock splits.
D) When a company declares a stock split, the price of the stock typically declines--for example, by about 50% after a 2-for-1 split--and this necessarily reduces the total market value of the firm's equity.
E) If a firm's stock price is quite high relative to most stocks--say $500 per share--then it can declare a stock split of say 20-for-1 so as to bring the price down to something close to $25. Moreover, if the price is relatively low--say $2 per share--then it can declare a "reverse split" of say 1-for-10 so as to bring the price up to somewhere around $20 per share.
Answer: E) If a firm's stock price is quite high relative to most stocks--say $500 per share--then it can declare a stock split of say 20-for-1 so as to bring the price down to something close to $25. Moreover, if the price is relatively low--say $2 per share--then it can declare a "reverse split" of say 1-for-10 so as to bring the price up to somewhere around $20 per share.
Explanation:
Stock Splits usually occur when a company believes that its stock price is relatively high compared to most other stocks.
If the stock is $500 per share, a stock split of 20-1 would divide the stock so that it comes to;
=500/20
= $25 per share.
If the company believes that prices are too low, they can do a reverse split or a stock merge to bring the price up by merging stocks together. If Stock is trading at $2 per share, a 1 - 10 would take it up to;
