As you learned more and more about the complexity of the HRM role, what do you view as the most challenging aspect of HRM in the international context? How do you view the impact of expatriates on your role in HRM?
Answer:
The interpretation including its question would be characterized in the explanatory segment elsewhere here.
Explanation:
(a)
The cultural divide is perhaps the most compelling as that of the complexities of corporation dramatically change in something like a foreign environment. Besides example, a thumbs-up gesture, which would be a complimentary sign throughout the West as well as the US, seems to have a different meaning in several other cultural groups and therefore is construed as bad-mannered throughout Asian countries like Thailand, whereby the significance has been less than that of trying to stick someone's hard to both the West.(b)
The negative effect of ex-pats mostly on the position of HRM would be that individuals start making the importance of HRM so much enlightening. The HR seems to be essential for safeguarding expatriates and then for the HR to safeguard foreign nationals, this should understand the ways of foreign residents such that the HR could even start educating other staff mostly on cultural values of migrants.Candice is a jewelry shop owner, specializing in beaded necklaces.

Warner Clothing is considering the introduction of a new baseball cap for sales by local vendors. The company has collected the following price and cost characteristics.
Sales price $15 per unit
Variable costs 5 per unit
Fixed costs 50,000 per month
Required:
a. What number must Warner sell per month to break even?
b. What number must Warner sell per month to make an operating profit of $34,000 and $8,400. Assume that the company plans to sell 9,000 units per month. Consider requirements (b), (c), and (d) independently of each other.
c. What will be the operating profit?
d. What is the impact on operating profit if the sales price decreases by 10 percent? Increases by 20 percent?
Answer:
a. 5,000 units
b. 8,400 units and 5,840 units
c. $40,000
d. decrease of operating profit by 22.50 % and increase of operating profit by 45.00%
Explanation:
Breakeven point is level at which a firm makes neither profit nor loss
Break even units = Fixed Costs ÷ Contribution per unit
Break even units = 5,000 units
Units to achieve target profit = Target Profit + Fixed Costs ÷ Contribution per unit
Units to achieve profit of $34,000 = 8,400 units
Units to achieve profit of $8,400 = 5,840 units
Operating Profit = Contribution - Fixed Costs
= $40,000
The effect on change of operating profit can be best shown by calculation of the Degree of Operating Leverage (DOL)
DOL = Contribution ÷ Profit
= 2.25
Sales decreases of 10 percent = decrease of operating profit by 22.50 % (10 % × 2.25)
Sales Increases of 20 percent = increase of operating profit by 45.00% (20%× 2.25)
Total Manufacturing Cost, Income Statement, Unit Cost, and Selling Price
Two inventors, recently organized as Innovation, Inc., consult you regarding a planned new product.They have estimates of the costs of materials, labor, overhead, and other expenses for 2016 but need to know how much to charge for each unit to earn a profit in 2016 equal to 15% of their estimated total long-term investment of $560,000 (ignore income taxes).
Their plans indicate that each unit of the new product requires the following:
Direct Material 4 lb. of a material costing $7 per lb.
Direct labor 2 hrs. of a metal former's time at $15.40 per hr. 0.6 hr. of an assembler's time at $11.20 per hr.
Major items of production overhead would be annual rent of $65,044 for a factory building, $40,124 rent for machinery, and $30,380 of indirect material. Other production overhead is estimated to be $326,592. Selling expenses are an estimated 30% of total sales, and non-factory administrative expenses are 20% of total sales.
The consensus at Innovation is that during 2016 10,000 units of product should be produced for selling and another 2.000 units should be produced for the next years beginning inventory. Also, an extra 3,000 pounds of material will be purchased as beginning inventory for the next year. Because of the nature of the manufacturing process, all units started must be completed, so work in process inventories are negligible.
Required
Incorporate the above data into a schedule of estimated total manufacturing costs and compute the unit production cost for 2016.
Answer:
1. Total manufacturing costs = $1,248,380
2. Unit production cost = $104.03 ($1,248,380/12,000)
Explanation:
a) Data and Calculations:
Long-term investment = $560,000
Expected annual profit = $84,000 ($560,000*15%)
Cost of direct materials per unit = $28 (4lb *$7)
Cost of direct labor per unit = $37.52 (2*$15.40) + (0.6*$11.20)
Total manufacturing overheads:
Rent for factory building = $65,044
Rent for machinery 40,124
Indirect materials 30,380
Other overheads 326,592
Total production overheads $462,140
Production:
Units sold = 10,000 units
Ending inventory of finished goods = 2,000 units
Total production for the year = 12,000 units
Direct materials purchase = 12,000 * 4 + 3,000 pounds = 51,000
Estimating the total manufacturing costs:
Direct materials costs = $357,000 ($28 * 12,750) or ($7 * 51,000)
less Ending inventory of raw materials = $21,000
Cost of direct materials used = $336,000 ($28 * 12,000 units)
Cost of direct labor = $450,240 ($37.52 * 12,000)
Production overhead = $462,140
Total manufacturing costs = $1,248,380
Cost per unit = $104.03 ($1,248,380/12,000)

Answer: The Sarbanes-Oxley Act of 2002, often simply called SOX or Sarbox, is U.S. law meant to protect investors from fraudulent accounting activities by corporations.
Explanation:
The Sarbanes-Oxley Act of 2002, often simply called SOX or Sarbox, is U.S. law meant to protect investors from fraudulent accounting activities by corporations. Here are the following sections passed;
Section 302 – Corporate Responsibility for Financial Reports – Every public company is required to file periodic financial reports with the SEC, and the principal executive officer and the principal financial officer must sign each report to indicate they have reviewed it and they certify that the report does not contain any untrue statements and does not omit any material information

During 2018, Raines Umbrella Corp. had sales of $810,000. Cost of goods sold, administrative and selling expenses, and depreciation expenses were $580,000, $90,000, and $135,000, respectively. In addition, the company had an interest expense of $91,000 and a tax rate of 21 percent. (Ignore any tax loss carryforward provisions and assume interest expense is fully deductible.) Suppose the company paid out $55,000 in cash dividends. If net capital spending and net working capital was zero, and if no new stock was issued during the year, what is the net new long-term debt
Answer:
$6,000
Explanation:
The computation of the net new long term debt is as follows:
But before that following calculations to be done:
Sales $810,000
Less: COGS ($580,000)
Less: S&A Expenses ($90,000)
Less: Depreciation ($135,000)
EBIT $5,000
Less: Interest ($91,000)
Taxable Income ($86,000)
Less: Taxes(21%) $0
Net Income(loss) ($86,000)
Now
OCF = EBIT + Depreciation - Taxes
= $5,000 + $135,000 - $0
= $140,000
Change in NWC = Net capital spending = Net new equity = 0
Cash flow from assets = OCF - Change in NWC - Net capital spending
= $140,000 - $0 - $0
= $140,000
Cash flow to stockholders = Dividends - Net New Equity
= $55,000 - $0
= $55,000
Cash flow to creditors = Cash flow from assets - Cash flow to stockholders
= $140,000 - $55,000
= $85,000
Cash flow to creditors = Interest - Net new LTD
$85,000 = $91,000 - Net new LTD
So,
Net new LTD is
= $91,000 - $85,000
= $6,000

The C&C Candy Company uses machine hours to allocate manufacturing overhead. The company estimates $150,000 worth of manufacturing overhead and 3,000 machine hours. The batch ticket for Batch 127 reveals the following information:
3,000 oz of chocolate at 50 cents per ounce
400 hours of direct labor at $15 per hour
180 machine hours 82,500 candy bars produced Batch Completed July 16, 2019.
Determine the cost of one bar.
Answer:
$0.20
Explanation:
Predetermined overhead rate = Estimated manufacturing overhead / Machine hours = 150000/3000 = 50
Applied overhead = Machine hours worked * Predetermined overhead rate = 180 * $50 = 9000
Direct material $1,500 (3,000*0.50)
Direct labor $6,000 (400 hours*$15)
Manufacturing overhead $9000
Total cost $16,500
Number of units = 82500 candy bars
So, the Unit cost = Total cost / Number of units = $16,500/82,500 units = 0.20
So, the cost of one bar is $0.20
Provide examples that serve to explain the differences among the following terms: (1) corporate responsibility; (2) corporate social initiatives; (3) corporate philanthropy
Answer: See explanation
Explanation:
Corporate responsibility is when an organization helps the society at large by contributing its own quota to the society and addressing certain social issues in such society. Example include giving scholarship to students.
Corporate social initiatives are used by organizations to address social problems, increase opportunities for the deprived, promote environmental justice etc. Examples include reduction in the carbon footprints and the improvement in labor policies.
Corporate philanthropy is when's business seeks the welfare of others and promote it. This is normally done through donation.
Mullineaux Corporation has a target capital structure of 60 percent common stock, 5 percent preferred stock, and 35 percent debt. Its cost of equity is 12 percent, the cost of preferred stock is 5 percent, and the pretax cost of debt is 7 percent. The relevant tax rate is 35 percent.
a. What is Mullineaux's WACC?
b. The companies president has approached you about Mullineaux's capital structure. He wants to know why the company doesn't use more preferred stock financing because it costs less than debt. What would you tell the president?
Answer:
a. Mullineaux's WACC = 0.60*12 + 0.05*5 + 0.35*7*(1 - 0.35)
WACC = 7.2 + 0.25 + 0.35*7*0.65
WACC = 7.2 + 0.25 + 1.5925
WACC = 9.0425%
WACC = 9.04%
b. After tax cost of debt = 7*(1 - 0.35)
After tax cost of debt = 7*0.65
After tax cost of debt = 4.55%
So since after tax cost of debt of 4.55% is less than the preferred cost of 5%, company should use debt in its capital structure.
Many influential economists, politicians, and business leaders think that a shift toward a more integrated and interdependent global economy is a good thing. There is evidence to support the theory that falling barriers to international trade and investment drive the global economy toward greater prosperity. There are, however, critics who argue against globalization. Anecdotes, evidence, and arguments can be collected to support each side of the debate.
International businesses need to understand the nature of the globalization debate and observe how their own practices may act in support of or against globalization. Understanding how each side sees the issues can lead toward better solutions to the problems caused by globalization.
Evaluate the issues listed on the left. Decide whether the issue is an Argument For Globalization or an Argument Against Globalization and who or what is being affected by the issue. Drag the issue to the appropriate column in the chart.

An investor owns 50 shares of a stock worth $15.30 per share. Which of the following is the amount of money to cashed in half of the shares of this stock?
a. $38.250.00 .
b. $382.50
c. $76,500.00
d. $765.00
Solution :
Given that a man owns shares = 50
Cost of one share = $ 15.30
Therefore the total amount of money for 50 shares would be = 50 x 15.30
= $ 765.00
We have to find the amount of money to be cashed in half of the shares for this stock of the investor.
Therefore, half of the shares at this stock is given by :
[tex]$=\frac{765.00}{2} $[/tex]
= 382.50
Therefore the answer is $ 382.50
Hence option (a) is correct.
Give an example of one good or service produced in the United States using the command model. Justify your example using research (where did you find this).
Answer:
An example of production under the command system in the United States is that of the production of roads and passable roads throughout the nation. In this case, it is the production of a public service, and as such it is controlled by the government in all stages of its production: from the identification of the need, through the tender, the construction authorization and the supervision of the results, everything is controlled by the government. This implies that individuals or private companies cannot by their own initiative create this type of road, but rather depend exclusively on the will of the government.
Smashed Pumpkins Co. paid $160 in dividends and $589 in interest over the past year. The company increased retained earnings by $492 and had accounts payable of $630. Sales for the year were $16,370 and depreciation was $732. The tax rate was 40 percent. What was the company's EBIT
Answer: $1675.67
Explanation:
Based on the information given in the question, the company's EBIT would be calculated as:
Earnings After Tax will be:
= Retained Earnings + Dividends
= 492 + 160
= 652
Earnings Before Tax will be:
= EAT / (1 - tax rate)
= 652 / (1 - 40%)
= 652 / (1 - 0.40)
= 652/0.60
= 1086.67
EBIT would then be calculated as:
= EBT + Interest
= 1086.67 + 589
= 1675.67

This question tests your understanding of the economics of a commodity tax. Assume that in each case the demand curve slopes down from top left to bottom right and the supply curve slopes up from bottom left to top right If the government halved a commodity tax, what would not always follow?
a. The quantity traded would increase
b. The price exclusive of commodity tax that sellers receive would rise.
c. The price inclusive of commodity tax that buyers pay would fall.
d. Tax revenue would increase.
Answer:
d. Tax revenue would increase.
Explanation:
When government halved commodity tax so they divided into two parts so it is use full them to manage it separately in two different parts. So when government needs more revenue they tax some commodity on their trade. So now government collects different taxes from different parties so their tax revenue increases by that decision.

P(x = x) = (λ^x * e^-λ) / x!
P(x = 1) = (2^1 *e^-2) / 1!
P(x = 1) = (2 * 0.1353352) = 0.2706
P(x ≥ 5) = 1 - P(x < 5)
1 - P(x < 5) = 1 - [p(x = 0) + p(x = 1) + p(x = 2) + p(x = 3) + p(x = 4)]
We obtain and add the individual probabilities. To save computation time, we can use a poisson distribution calculator :
1 - P(x < 5) = 1 - (0.13534+0.27067+0.27067+0.18045+0.09022)
1 - P(x < 5) = 1 - 0.94735 = 0.05265
P(x ≥ 5) = 1 - P(x < 5) = 0.05265
Probability that no emails was received :
x = 0
P(x = 0) = (2^0 *e^-2) / 0!
P(x = 0) = (1 * 0.1353352) / 1 = 0.1353
