Assume that you have entered into a fixed for fixed currency swap agreement under which every 6 months you agree to pay 3% on a notional of 110M USD and receive 4% on a notional of 100M EUR. On the date you signed the contract the spot exchange rate is 1.1 USD/EUR. Six months later the spot exchange rate is 1.05 USD/EUR. Your actual payment net of what you receive at the first payment date equals to :__________
Answers
Answer: -0.55M USD
Explanation:
The payment made will be:
= 3%/2 × 110M USD
= 0.03/2 × 110M USD
= 1.65M USD
The amount received will be:
= 4%/2 × 100M EUR
= 2% × 100M EUR
= 0.02 × 100M EUR
= 2M EUR
Since exchange rate = 1.1 USD/EUR
2M EUR = 2 × 1.1 = 2.2M USD
Therefore, net payment will be:
= 1.65M - 2.2M
= - 0.55M USD
WiseGuy Capital mutual fund has $200 million in assets and 10 million shares at the start of the year and with $250 million in assets and 11 million shares at the end of the year. During the year investors have received income distributions of $2 per share and capital gain distributions of $.25 per share. Assuming that the fund carries no debt, does not charge any load, and the total expense ratio is 2%, what is the rate of return on the fund
Answers
Answer:
The return rate on the fund is "23.75%".
Explanation:
The given values are:
In the starting of the year,
Mutual fund assets,
= $200
Share,
= 10 million
In the end of the year,
Income distribution,
= $2 per share
Capital gain distribution,
= $.25 per share
Total expense ration,
= 2%
Now,
The initial NAV will be:
= [tex]\frac{200mn}{10mn}[/tex]
= [tex]20[/tex]$
The final NAV will be:
= [tex]250-\frac{250\times 0.01}{11}[/tex]
= [tex]22.5[/tex]
hence,
The return will be:
= [tex]\frac{Change \ in \ NAV+Div+Capital \ gain \ distribution}{Initial \ NAV}[/tex]
On substituting the values, we get
= [tex]\frac{22.5-20+2+0.25}{20}[/tex]
= [tex]\frac{4.75}{20}[/tex]
= [tex]0.2375[/tex]
i.e.,
= [tex]23.75[/tex]%
Macmillan Toys Inc. is located in the nation of Ruffino near the nation of East Fenwick. Macmillan Toys is considering expanding into Rusalka. Both countries have similar consumer incomes and knowledge bases and share a common language. Also, the transportation networks between the countries are strong. Even so, the two nations have a long-standing dispute concerning the control of an area of land along their common border. Currently, Ruffino rules this land.
What would most likely prevent Macmillan Toys from expanding into Rusalka?
Answers
Answer: Political Distance
Explanation:
Political distance refers to a difference in opinion and policies as well as relations that countries have amongst themselves. In this scenario, this is the most likely bone of contention that would prevent Macmillan Toys from expanding into Rusalka.
This is because land disputes fall under political distance and can get very serious. So serious in fact that nations have gone to war over such disputes with the latest being Azerbaijan and Armenia. Macmillan Toys may therefore find it difficult to expand into the country due to this land dispute.

Coffee Klatch is an espresso stand in a downtown office building. The average selling price of a cup of coffee is $1.49 and the average variable expense per cup is $0.36. The average fixed expense per month is $1,300. Use the formula method to determine how many cups of coffee would have to be sold to attain target profits of $3,000 per month.
Answers
Answer:
See below
Explanation:
The formula method is denoted by
Unit sales to attain the targeted profit =( Target profit + Fixed expenses) / Contribution margin per unit
Target profit = $3,000 per month
Fixed expenses = $1,300
Contribution margin per unit = $1.49 - $0.36 = $1.13
Therefore, unit sales to attain targeted profit = ($3,000 + $1,300) / $1.13 = 3,805.31 units
It means that 3,805.31 cup of coffee would have to be sold to attain target profit of $3,000 per month.

Bummerland finds itself in a recession caused, as assumed in class, a sticky nominal (money) wage (W) which is too high to clear the labor market.
Bummerland has a Treasury and a "Federal Reserve" (called the Bummerb¬ank). At a meeting of officials of both agen¬cies, various antirecess¬ionary policies are considered. The economic staffs of both agencies are seriously split on issues such as how interest sensitive investment is and how interest sensitive the demand for money is. However, they are in agreement that the marginal propensity to consume (b) is .75 and the marginal propensity to hold cash (k) is .2. Bummerland has banks, but the reserve requirement is 100%, so they don't create money.

Answers
Answer:
the variable overhead efficiency variance is $1,840 unfavorable
Explanation:
The computation of the variable overhead efficiency variance is shown below:
= Standard variable overhead rate × (standard hours - actual hours)
= $4.60 × (10,600 - 11,000)
= $1,840 unfavorable
Hence, the variable overhead efficiency variance is $1,840 unfavorable
As the standard hours would be less than the actual hours so it would be unfavorable variance

Direct material budget. Inglenook Co. produces wine. The company expects to produce 2,500,000 two-liter bottles of Chablis in 2015. Inglenook purchases empty glass bottles from an outside vendor. Its target ending inventory of such bottles is 80,000; its beginning inventory is 50,000. For simplicity, ignore breakage. Compute the number of bottles to be purchased in 2015.
Answers
Answer:
2,530,000 bottles
Explanation:
Regarding the above information, we will compute the number of bottles to be purchased in 2015 as seen below
Purchase in units = Usage + Desired ending material inventory units - Beginning inventory units
Purchase in units = 2,500,000 + 80,000 - 50,000
Purchase in units = 2,530,000
Therefore, the number of bottles to be purchases in 2015 is 2,530,000
g Mad Mex just paid a dividend of $4.00. Next year they anticipate paying a dividend of $6 and then a dividend of $7 in the subsequent year. After that point, the company plans to grow dividends by at a constant 5% growth rate forever. Your required rate of return for the stock is 10%. What is the market value of the stock
Answers
Answer:
The market value of the stock is $132.73.
Explanation:
D0 = Dividend just paid = $4
D1 = Anticipated next year dividend or Year 1 dividend = $6
D2 = Dividend of in the subsequent year or Year 2 = $7
D3 = Year 3 dividend = D2 * (100% + Dividend growth rate forever) = $7 * (100% + 5%) = $7.35
Sum of present values of D1 and D2 = (D1 / (100% + required rate of return)^1) + (D2 / (100% + required rate of return)^2) = ($6 / (100% + 10%)^1) + ($7 / (100% + 10%)^2) = $11.2396694214876
Stock price in year 2 = D3 / (Required rate of return - Dividend growth rate forever) = $7.35 / (10% - 5%) = $147
Present value of Stock price in year 2 = Stock price in year 2 / (100% + required rate of return)^2 = $147 / (100% + 10%)^2 = $121.487603305785
Market value of the stock = Present value of Stock price in year 2 + Sum of present values of D1 and D2 = $121.487603305785 + $11.2396694214876 = $132.73
Therefore, the market value of the stock is $132.73.

Consider a series of end-of-period CFs spanning 2040-2050, which increase by a fixed amount each period. The amount of the first CF in the series is $149 and the increment is $76. The nominal interest rate is 1.3%; compounding occurs 5 times per year. What is the equivalent value of this series at the beginning of 2040
Answers
Answer:
The equivalent value of the series=$ 10,536.61
Explanation:
An annuity is a series of equal payment or receipt occurring for certain number of period.
The series of cash flows of $149 and the increase $76 occurring for 10 years are example of ordinary annuity.
So we can workout their present value using the formula stated below:
This is done as follows:
The Present Value of annuity = A × (1- (1+r)^(-n))/r
Present value of series of fixed amount cashflow
A- periodic cash flow-149, r- semi annual rate of interest - 1.3/5= 0.26%
n- number of period- (10×5) = 50.
Present value = 149× (1-1.0026^(-50)/0.0026=6,977.57
Present value of the increment series of cashflow
A- periodic cash flow-76, r- semi annual rate of interest - 1.3/5= 0.26%
n- number of period- (10×5) = 50.
Present value = 76× (1-1.0026^(-50)/0.0026=3,559.03
The equivalent value of the series = Present value of the fixed amount + present value of the increment= 6,977.57 + 3,559.03= 10536.61
The equivalent value of the series=$ 10,536.61

Answers
Answer:
Lump sum= $2,242,403.85
Explanation:
First, we need to calculate the future value of the annual payments using the following formula:
FV= {A*[(1+i)^n-1]}/i
A= annual payment
FV= {165,000*[(1.04^20) - 1]} / 0.04
FV= $4,913,382.97
Now, the lump sum is the present value of the annual payments:
PV= FV / (1 + i)^n
PV= 4,913,382.97 / (1.04^20)
PV= $2,242,403.85

Coffee Klatch is an espresso stand in a downtown office building. The average selling price of a cup of coffee is $1.49 and the average variable expense per cup is $0.24. The average fixed expense per month is $1,600. An average of 2,100 cups are sold each month. What is the CM Ratio for Coffee Klatch?
Answers
Answer:
The contribution margin ratio for Coffee Klatch is 83%.
Explanation:
Given that Coffee Klatch is an espresso stand in a downtown office building, and the average selling price of a cup of coffee is $ 1.49 and the average variable expense per cup is $ 0.24, and the average fixed expense per month is $ 1,600, to determine what is the CM Ratio for Coffee Klatch if an average of 2,100 cups are sold each month, the following calculation must be performed:
Contribution margin ratio: (sales - variable costs) / sales
((2,100 x 1.49) - (2,100 x 0.24)) / (2,100 x 1.49) = X
(3.129 - 504) / 3.129 = X
2.625 / 3.129 = X
0.83 = X
Thus, the contribution margin ratio for Coffee Klatch is 83%.

The dividend discount model (DDM) can be used to calculate the price of the stock today. DDM calculates the price of a stock based on the present value of the expected future dividends from the stock. The formula for price today under DDM is,
P0 = D1 / (1+r) + D2 / (1+r)^2 + ... + Dn / (1+r)^n + [(Dn * (1+g) / (r - g)) / (1+r)^n]
Where,
D1, D2, ... , Dn is the dividend expected in Year 1,2 and so on g is the constant growth rate in dividends r is the discount rate or required rate of return
P0 = 4.6 * (1+0.05) / (1+0.07) + 4.6 * (1+0.05) * (1+0.04) / (1+0.07)^2 +
4.6 * (1+0.05) * (1+0.04) * (1+0.03) / (1+0.07)^3 +
[(4.6 * (1+0.05) * (1+0.04) * (1+0.03) * (1+0.02) / (0.07 - 0.02)) / (1+0.07)^3]

Record the above transactions in a horizontal statements model.
Answers
Answer:
Cash + Equipment - Accumulated depreciation = Common stock + Retained = $46,460
Explanation:
Note: See the attached excel file for the horizontal statements model.
In the attached excel file, we have:
Accumulated depreciation = (Cost of cooktop or equipment - Estimated salvage value) / Expected useful life = ($39,000 - $3,200) / 5 = $2,440
From the attached excel file, the accounting equation can be proved from the balances as follows:
Cash + Equipment - Accumulated depreciation = $33,500 + 15,400 - $2,440 = $46,460
Common stock + Retained = $39,000 + $7,460 = $46,460
Therefore, we have:
Cash + Equipment - Accumulated depreciation = Common stock + Retained = $46,460

Profit from Lease Equipment (Alternative 1) = $280,000
Profit from Sell Equipment (Alternative 2) = $288,000
Differential Effects = Net gain from selling = $8,000
B. Should Plymouth Company lease (Alternative 1) or sell (Alternative 2) the equipment?
Since the net gain from selling is $8,000, Plymouth Company should sell (Alternative 2) the equipment.
The failure rate for each component of a 2-component series system is assumed to be one failure per 1,000 hours of operation, and the switch reliability of replacing a failed component with a spare one is 1.0. Given that there is a spare component, a. Calculate the reliability of the system for a period of 1,000 hours assuming no other failure is possible. b. Determine the approximate MTBF of the system. c. What is the system MTBF without the spare component
Answers
Answer:
a. The reliability of the system for a period of 1,000 hours, assuming no other failure is possible is:
= 99.9%.
b. The approximate MTBF (Mean Time Between Failures) without the spare component is:
1,000 hours.
Explanation:
a) Data and Calculations;
Failure rate of each component of a 2-component series system = 1/1,000 = 0.001
Therefore, the reliability rate = 1 - 0.001 = 0.999 = 99.9%
The switch reliability of replacing a failed component with a spare one = 1.0
The system's reliability = Mean Time Between Failure (MTBF) minus the Mean Time to Repair (MTTR)
= 1,000 - 1.0 = 999 hours out of 1,000
b)The equipment's Mean time between failures (MTBF) is the average time it takes the equipment or system to suffer a breakdown. Engineers, vendors, and system analysts use the MTBF metric to measure an equipment's performance, safety, and design reliability.
