A firm has three years remaining on an existing finite project. Management is evaluating an Enhancement Opportunity (new project) that lowers SG&A expenses and reduces the amount of Required Cash necessary to complete this existing project. This Enhancement Opportunity will not materially affect COGS or any other net operating work capital accounts such as A/R, Inventory and A/P.

Projected Capital Expenditures (Capex) will be $18 million in 2019, $6 million in 2020, and $4 million in 2021. Assume that all Capex will be spent at the beginning of each year (for instance, the $18 million 2019 Capex will be spent at time = 0). Assume that you recognize operating cash flows (ie. Income statement items) in the middle of the year. Assume that the Net PP&E can be sold for $11 million at the end of 2021, and that you “recoup” (free up) the Required Cash two months after the sale of the equipment.

You estimate the WACC of this Enhancement Opportunity at 9.0%, and the relevant incremental tax rate is 21.0%. Calculate the NPV of this project.

Items 7 through 11 refer to the admission procedure for Watsamata University, a small private University in Minnesota. Watsamata University requires all applicants to complete an admission examination specifically developed for the University. The test is composed of 100 multiple-choice items. To evaluate the utility of test for admission decisions the university conducted a pilot study in which, for one year, all students who were admitted to the university took the test. The descriptive statistics from the study are presented in Table 1. The relationship between scores on the admission test and freshman year GPA is displayed in the scatter plot shown in Figure 1.

7. Using the available data, what is the reliability of this data. (5 points)

8. Using your response to item seven, what would you expect the reliability of the data to be if the number of test items were increased to 150? (5 points)

9. Construct a regression formula for this test and freshman GPA, and use it to calculate the predicted freshman year GPA for the student who scored 63 on the admissions examination. What range of scores would you predict, with 90% confidence, for this student’s first year GPA? (10 points)

10. The admissions department assumes that subsequent classes will exhibit the same pattern of performance on the admission test, and that the relationship between the admissions examination and the students’ freshman GPA is relatively stable. Watsamata University has a very simple admission procedure. If a student scores 60 or better on the admission examination, he or she is accepted. In addition students must maintain a 2.0 GPA to continue their studies at Watsamata University. Given this information, is the use of the test likely to enhance the validity of admission decisions made by Watsamata University? Justify your answer using the concepts discussed in class. (10 points)

11. Watsamata University is investigating whether or not its admission test exhibits gender bias. To do this they used the data from the pilot group. The descriptive statistics for male and female applicants, as well as the respective correlation coefficients appear Table 2.

Terephthalic acid (TPA), a raw material in the manufacture of polyester fiber, film, and soft… 1 answer below »

Terephthalic acid (TPA), a raw material in the manufacture of polyester fiber, film, and soft drink bottles, is synthesized from p-xylene (PX) in the process shown below. A fresh feed of pure liquid PX combines with a recycle stream containing PX and a solution (S) of a catalyst (a cobalt salt) in a solvent (methanol). The combined stream, which contains S and PX in a 3:1 mass ratio, is fed to a reactor in which 90% of the PX is converted to TPA. A stream of air at 25°C and 6.0 atm absolute is also fed to the reactor. The air bubbles through the liquid and the reaction given above takes place under the influence of the catalyst. A liquid stream containing un-reacted PX, dissolved TPA and all the S that entered the reactor goes to a separator in which solid TPA crystals are formed and filtered out of the solution. The filtrate, which contains all the S and PX leaving the reactor, is the recycle stream. A gas stream containing un-reacted oxygen, nitrogen, and the water formed in the reaction leaves the reactor at 105°C and 5.5 atm absolute and goes through a condenser in which essentially all the water is condensed. The uncondensed gas contains 4.0 mole% O2.

(a) Taking 100kmol TPA produced/h as a basis of calculation, draw and label a flowchart for the process.

(b) ?~What is the required fresh feed rate (k mol PX/h)?

(c) What are the volumetric flow rates (m3/h) of the air fed to the reactor, the gas leaving the reactor, and the liquid water leaving the condenser? Assume ideal gas behavior for the two gas streams.

(d) What is the mass flow rate (kg/h) of the recycle stream?

(e) Briefly explain in your own words the functions of the oxygen, nitrogen, catalyst, and solvent in the process.

(f) In the actual process, the liquid condensate stream contains both water and PX. Speculate on what might be done with the latter stream to improve the economics of the process.

Coca-Cola is an American company that manufactures the carbonated soft drinks. It’s history date

Coca-Cola is an American company that manufactures the carbonated soft drinks. It's history dates back more than 100 years ago, when it was invented by John Pemberton as a medicine. Coca-Cola history began in 1886 when the curiosity of an Atlanta pharmacist, Dr. John S. Pemberton, led him to create a distinctive tasting soft drink that could be sold at soda fountains. It was later bought out by businessmen Asa Griggs Candler, whose mission and vision has led the company to achieve dominant status in the market of soft-drinks. The drink's name came from two of its ingredients: coca leaves and kola nuts. The company does not produce the product itself, instead they produce the concentrate which are then shipped and sold to their licensed bottlers, who hold the exclusive rights of producing the Coca-Cola drinks. After bottling, these products are supplied to the retailers, distributors, vendors, restaurants throughout the world. The company has diversified its business by producing various product mixes such as carbonated soft-drinks, fruit flavored soft-drinks, fresh fruit juices, mineral water, and energy drinks. The company is selling its brand in almost every country of the world. Currently, the company is holding a leader's position in the soft-drinks industry and is expected to retain the title for years to come as no other competitor except PepsiCo, is anywhere near Coca-Cola.

www.worldofcoca-cola.com/about-us/coca-cola-history/

The company has faced the following realities during its operations:

Political: The products of Coca-Cola are regulated by government for use of its ingredients and the company must comply with strictly, in order to carry their operations. Any change in the law can affect the operations of Coca-Cola.

Economic: Coca-Cola has its presence in most of the countries of the world. The customers of these different countries are being served according to their regional taste and requirements and Coca-Cola has customized their products in required ways. The economic position of company is mostly dependent on the beverage industry and most of it comes outside of USA. So, the company needs to carefully monitor the market conditions and requirements of customers of that particular country.

Social: Customers all over the world are becoming increasingly health conscious. They don't want to drink these fatty and sugary carbonated soft-drinks. This aspect needs to be studied by the company. Now, it has introduced recently low fat and low sugar drinks which may help the change in the desire for healthier choices for the needs of the health conscious customers.

The major conditions under which the company has to operate are:

• In many countries, it has detected that the company is using some of the ingredients above the harmful levels due to which the operations of the company came under the government regulations. Such instances should not happen in future.

• The company is facing competition from its main competitor PepsiCo and other soft-drinks manufacturers at local levels. It is required for the company to maintain the quality and taste of the products with optimum customization according to customers tastes.

• The customers are becoming health conscious recently. They tend to avoid carbonated soft-drinks and like to drink some healthy drink. The company needs to look to create products which may cater to the needs of these type of customers.

• In many countries, the latest technology of automated bottling plants may not be available, which increase the production. The company may look to provide them with latest technologies to increase the production at local levels and avoid costly transportation of its products from other places.

Back, A. (2018, July 26). Low Sugar Innovations Sweeten Coke’s Growth. Wall Street Journal – Online Edition. p. 1.

Management has had to rethink its portfolio as consumers move away from the sugary drinks that have fueled its empire. Coca-Cola has invested in juices, teas, coffees, and beverages made with organic and natural ingredients. They also have been reducing sugar, using alternative sweeteners throughout its existing portfolio, and offering smaller can sizes. Revenue was down for the year, as were profits, which took a hit from a $3.6 billion one-time charge related to tax reform.
