Scenario

DoEpicStuff started as a 3 person start-up. Two of these three people wrote code. Each coder would create database tables as needed. There was no naming convention for the database tables or the fields of the table. There was no established process for checking whether the two tables had fields in common and in that case whether they had the same name or the same data type. The coders were free to add columns to (or even drop columns from) each others tables. This caused unexpected code failures.

DoEpicStuff managed to get funding from investors and added more staff very quickly. The new coders would write code that reference tables created by the earlier two employees. Their code often contained bugs because they assumed data that referred to a certain field would contain the same type of data in another field with the same name in a different table. They also acquired some new contracts which required handling sensitive information. The CEO instructed each employee as to what data in which tables they could access, but there was no mechanism for enforcing it.

DoEpicStuff acquired some valuable data repositories from another start-up, BellyUp, that had just gone bankrupt. Data from BellyUp was also referenced in some of the code. But there was no effort made to ascertain the data quality of this data. Indeed, the data collected by DoEpicStuff overlapped with some of the data from BellyUp but no effort was made to determine which of the over-lapping data was more current or which should be trusted. Individual coders decided on a ad-hoc basis whether to use data from BellyUp or from DoEpicStuff.

Some of the coders aggregated data manually from some of the tables and entered them into other tables. But after a while no one could remember where this aggregated data came from. Because of employee turnover it was unclear who had done which part of the aggregation.

The sales and marketing team of DoEpicStuff needed to prepare some marketing material and needed accurate statistics to be included in the marketing material. But they had no one to turn to find out which data was accurate and current.

1. Identify as many problems as possible with how DoEpicStuff manages its data assets, with a one or two sentence explanation of why you think each problem you have identified is a problem.
2. Provide a suggestion for a set of data governance policies that will fix the data management problems you have identified in Step 1. For each policy you recommend, clearly identify the problems it will fix and with a two or three sentence justification for why you think it will fix these problems.

1. Suppose we have two sets of prediction for the inflation rate for next year: one from a random sample of Fortune 500 firms and another from a random sample of university economists. At 0.05 level can it be claimed that on the average university educators are predicting a higher inflation rate for next year than the major private businesses?

You are a CIMA (Chartered Institute of Management Accountants) member who is a non-executive director of a large services company. The board of directors meets on a monthly basis to discuss the quarterly forecast and other business issues.It is the responsibility of the finance director to distribute papers at least two weeks prior to the date of the meeting. These papers should first be signed off by the CEO. Recently documents have only been received a day before the meeting. You have raised this with the finance director who has stated the delay is due to the sign-off by the CEO. You do not feel that you are given sufficient time to review the papers, and also believe the information that is available is not complete and therefore difficult to fully appraise. The CEO is a very dominant character and many members of the board are nervous about broaching the matter. What would you do?

You will be conducting research for Mcdonald and providing analysis on how the economy is doing. You are going to act as a consultant and provide economic research using 2-3 different data indicators/points. You are going to find two relevant economic data indicators(examples, unemployment rate, inflation rate, employment rate, GDP, producer price index….etc) that are relevant to your industry and evaluate how the industry is going to be doing in the next 6 months given the economic data and forecasts that you have evaluated. You are going to be consulting with the CEO to give him your predictions and what he should plan on doing in his job given the current economic situation. Make sure that you are clear and concise with the data indicator that you selected and why you selected it. You will need to make sure to focus on how the data indicator will focus on the industry that you selected and the decisions that businesses will be facing in the upcoming months with your advice. The CEO is relying on your evaluations to make sure that his company does well. You will be graded on the quality of your argument to the CEO, use of data indicators and application to industry, analysis of content

You manage a company located in the U.S. and the profits you report to your shareholders are in $US. Today your company signed a contract with a Canadian company to import computer parts from Canada with delivery 6 months from today and with the price of the parts in Canadian dollars. You will use these parts to build computers in the U.S. and sell the computers to a Japanese company. You have also signed a contract with the Japanese company today specifying the price per computer in Japanese yen for delivery in one year. There are future contracts in Canadian dollars and in Japanese yen, both priced in U.S. dollars per unit of foreign currency (e.g. $1.3 per Canadian dollar and $.01 per yen). Explain the exchange rate risks your company faces and how you would hedge these risks using futures contracts

In this problem, assume that the distribution of differences is approximately normal. Note: For degrees of freedom d.f. not in the Student's t table, use the closest d.f. that is smaller. In some situations, this choice of d.f. may increase the P-value by a small amount and therefore produce a slightly more "conservative" answer.

Are America's top chief executive officers (CEOs) really worth all that money? One way to answer this question is to look at row B, the annual company percentage increase in revenue, versus row A, the CEO's annual percentage salary increase in that same company. Suppose a random sample of companies yielded the following data:

Do these data indicate that the population mean percentage increase in corporate revenue (row B) is different from the population mean percentage increase in CEO salary? Use a 5% level of significance. (Let d = B − A.)

(a) What is the level of significance?


State the null and alternate hypotheses.

H₀: μ_d = 0; H₁: μ_d > 0H₀: μ_d > 0; H₁: μ_d = 0    H₀: μ_d = 0; H₁: μ_d < 0H₀: μ_d = 0; H₁: μ_d ≠ 0H₀: μ_d ≠ 0; H₁: μ_d = 0

(b) What sampling distribution will you use? What assumptions are you making?

The Student's t. We assume that d has an approximately normal distribution.The Student's t. We assume that d has an approximately uniform distribution.    The standard normal. We assume that d has an approximately uniform distribution.The standard normal. We assume that d has an approximately normal distribution.

What is the value of the sample test statistic? (Round your answer to three decimal places.)


(c) Find (or estimate) the P-value.

P-value > 0.5000.250 < P-value < 0.500    0.100 < P-value < 0.2500.050 < P-value < 0.1000.010 < P-value < 0.050P-value < 0.010

Sketch the sampling distribution and show the area corresponding to the P-value.

(d) Based on your answers in parts (a) to (c), will you reject or fail to reject the null hypothesis? Are the data statistically significant at level α?

Since the P-value ≤ α, we fail to reject H₀. The data are statistically significant.Since the P-value > α, we reject H₀. The data are not statistically significant.    Since the P-value > α, we fail to reject H₀. The data are not statistically significant.Since the P-value ≤ α, we reject H₀. The data are statistically significant.

(e) Interpret your conclusion in the context of the application.

Reject H₀. At the 5% level of significance, the evidence is sufficient to claim a difference in population mean percentage increases for corporate revenue and CEO salary.Reject H₀. At the 5% level of significance, the evidence is insufficient to claim a difference in population mean percentage increases for corporate revenue and CEO salary.    Fail to reject H₀. At the 5% level of significance, the evidence is insufficient to claim a difference in population mean percentage increases for corporate revenue and CEO salary.Fail to reject H₀. At the 5% level of significance, the e

Suppose that you are part of the Management team at Porsche. Suppose that it is the end of December 2019 and a novel coronavirus that causes a respiratory illness was identified in Wuhan City, Hubei Province, China. The illness was reported to the World Health Organization and there is heightened uncertainty around the Globe.

You (as part of the management team) are reviewing Porsche’s hedging strategy for the cash flows it expects to obtain from vehicle sales in North America during the calendar year 2020. Assume that Porsche’s management entertains three scenarios:

Scenario 1 (Expected): The expected volume of North American sales in 2020 is 35,000 vehicles.

Scenario 2 (Pandemic): The low-sales scenario is 50% lower than the expected sales volume.

Scenario 3 (High Growth): The high-sales scenario is 20% higher than the expected sales volume.

Assume, in each scenario, that the average sales price per vehicle is $85,000 and that all sales are realised at the end of December 2020. All variable costs incurred by producing an additional vehicle to be sold in North America in 2020 are billed in euros (€) and amount to €55,000 per vehicle. Shipping an additional vehicle to be sold in North America in 2020 are billed in € and amount to €3,000 per vehicle.

The current spot exchange rate is (bid-ask) $1.11/€ - $1.12/€ and forward bid-ask is $1.18/€ - $1.185/€. The option premium is 2.5% of US$ strike price, and option strike price is $1.085/€. Your finance team made the following forecasts about the exchange rates at the end of December 2020:

• bid-ask will be $1.45/€ - $1.465/€ if the investors (and speculators) consider the euro (€) a safe haven currency during the pandemic.
• bid-ask will be $0.88/€-$0.90/€ if the investors (and speculators) consider the U.S. dollar ($) a safe haven currency during the pandemic

1. You decided not to hedge Porsche’s currency exposure. If the expected final sales volume is

35,000, what are your total revenues

1. if the exchange rate (bid-ask) remains at $1.11/€ - $1.12/€? Let’s call this the baseline scenario.
2. if the investors consider the euro a safe haven currency during the pandemic? How does this compare to the baseline case?
3. if the investors consider the U.S. dollar a safe haven currency during the pandemic? How does this compare to the baseline case?

2. Assume that you and the Porsche’s management team decided to hedge using forward contracts. Assume that the expected final sales volume is 35,000. What are your total benefit/cost and the percentage benefit/cost from hedging (compared to no hedging)

a) if the exchange rate (bid-ask) remains at $1.11/€ - $1.12/€?

b) if the investors consider the U.S. dollar a safe haven currency during the pandemic?

Questions 1 - 6 are based on the following information: B A US multinational corporation has operations in Bolivia through which it plans to sell a new product of 500,000 cans of beans per year for the next 3 years, at a price of BOB 4 per can after incurring a variable cost of BOB 2.50 per can. The company will also incur a fixed cost of $120,000 per year. The company has invested $900,000 today in manufacturing equipment for its Bolivian operations, which will be depreciated to $0 at the end of its 3-year life. The corporation's required rate of return is 20 % and has a tax rate of 25 %. The spot rate was BOB 6.91/$ before it unexpectedly changed to BOB 7.25/$. 1. What is the value of the Bolivian operations prior to the unexpected change in the spot rate assuming the operations have a 3-year life only? (round to the nearest dollar) A). US$237,699 B). US$166,903 C). US$107,453 D). US$159,076 E). None of the above
