In 2017, Congress enacted a bill that 1) reduced the corporate tax rate from 35% to 21% and 2) allowed the immediate write-off of capital spending. 3) disallowed the expensing of interest paid on debt. Discuss at a high level, how each of these changes will likely affect your valuations. (e.g. stock price, P/E ratio, ROR, WACC).

Research has shown that several biases can have an effect on performance appraisals. Choose three of the bias effects described in your readings (e.g., similar-to-me, physical attractiveness, age, etc.), and describe how an a organization can make systemic changes (i.e., do not just suggest that individuals change their thinking) to avoid these bias effects in performance appraisals.

Conch Republic Electronics is a midsized electronics manufacturer located in Key West, Florida. The company president is Shelly Couts, who inherited the company. The company originally repaired radios and other household appliances when it was founded more than 70 years ago. Over the years, the company expanded, and it is now a reputable manufacturer of various specialty electronic items. Jay McCanless, a recent MBA graduate, has been hired by the company in its finance department. One of the major revenue-producing items manufactured by Conch Republic is a smartphone. Conch republic currently has one smartphone model on the market and sales have been excellent. The smartphone is a unique item in that it comes in a variety of tropical colors and is preprogrammed to play Jimmy Buffett music. However, as with any electronic item, technology changes rapidly, and the current smartphone has limited features in comparison with new models. Conch Republic spent $1.2 million to develop a prototype for a new smartphone that has all the features of the existing one but adds new features such as Wifi tethering. The company has spent a further $250,000 for a marketing study to determine the expected sales figures for the new smartphone. Conch Republic can manufacture the new smartphone for $210 each in variable costs. Fixed costs for the operation are estimated to run $5.3 million per year. The estimated sales volumes are 64,000, 106,000, 87,000, 78,000, and 54,000 per year for each of the next five years, respectively. The unit price of the new smartphone will be $515. The necessary equipment can be purchased for $38.5 million and will be depreciated on a seven-year MACRS schedule. It is believed the value of the equipment in five years will be $5.8 million. Net working capital for the smartphones will be 20 percent of sales and will occur with the timing of the cash flows for the year (i.e., there is no initial outlay for NWC). Changes in NWC thus will occur first in year 1 with the first year’s sales. Conch Republic has a 22 percent corporate tax rate and a required return of 12 percent. Shelly has asked Jay to prepare a report that answers the following questions:

6) what is the payback period of the project?

7) What is the profitability index of the project?

8) What is the IRR of the project?

9) What is the NPV of the project?

10) How sensitive is the NPV to changes in the price of the new smartphone?

11) How sensitive id the NPV to changes in the quantity sold?

12) Should Conch Republic produce the new smartphone?

Kaelea, Inc., has no debt outstanding and a total market value of $165,000. Earnings before interest and taxes, EBIT, are projected to be $9,900 if economic conditions are normal. If there is strong expansion in the economy, then EBIT will be 24 percent higher. If there is a recession, then EBIT will be 31 percent lower. The company is considering a $46,500 debt issue with an interest rate of 5 percent. The proceeds will be used to repurchase shares of stock. There are currently 5,500 shares outstanding. Assume the company has a market-to-book ratio of 1.0.

Scenario

You are the nurse working triage in the emergency department (ED). This afternoon a woman brings in her father, ALI, a 72-year-old who is a retired doctor. The daughter reports that over the past several months she has noticed her father has progressively had problems with his mental capacity. These changes have developed gradually but seem to be getting worse. At times he is alert, and at other times he seems disoriented, depressed, and tearful. He is forgetting things and doing things out of the ordinary, such as placing the milk in the cupboard and sugar in the refrigerator. He had difficulty finding objects in the kitchen and at times forgets where his room is.

This morning he thought it was nighttime and wondered what his daughter was doing at his house. He could not pour his coffee, and he seems to be getting more agitated. ALI reports that he has been having memory problems for the past year and at times has difficulty remembering the names of family members and friends.

A review of his past medical history (PMH) is significant for hypercholesterolemia and coronary artery disease (CAD). He had a myocardial infarction (MI) 5 years ago. ALI’s vital signs (VS) today are all within normal limits (WNL).

To investigate the fluid mechanics of swimming, twenty swimmers each swam a specified distance in a water-filled pool and in a pool where the water was thickened with food grade guar gum to create a syrup-like consistency. Velocity, in meters per second, was recorded and the results are given in the table below.

The researchers concluded that swimming in guar syrup does not change mean swimming speed. Are the given data consistent with this conclusion? Carry out a hypothesis test using a 0.01 significance level. (Use μ_d = μ_water − μ_{guar syrup}.)

State the appropriate null and alternative hypotheses. (Multiple Choice, pick one of these choices)

A)

H₀: μ_d = 0

H_a: μ_d > 0

B)

H₀: μ_d = 0

H_a: μ_d ≠ 0

C)   

H₀: μ_d < 0

H_a: μ_d = 0

D)

H₀: μ_d ≠ 0

H_a: μ_d = 0

E)

H₀: μ_d = 0

H_a: μ_d < 0

Find the test statistic and P-value. (Round your test statistic to one decimal place and your P-value to three decimal places.)

t=

P-value=

State the conclusion in the problem context.(Multiple Choice, pick one of these choices)

A-We fail to reject H₀. The data provide convincing evidence that swimming in guar syrup changes mean swimming speed.

B-We reject H₀. The data provide convincing evidence that swimming in guar syrup changes mean swimming speed.   

C-We fail to reject H₀. The data do not provide convincing evidence that swimming in guar syrup changes mean swimming speed.

D-We reject H₀. The data do not provide convincing evidence that swimming in guar syrup changes mean swimming speed.

A) Refer to the diagram on “Speed Control of a Shunt Wound DC Motor.

Suppose the no load voltage V = 90V, R_a + R₁ = 4 ohms, R_sh + R_F = 130 ohms, and the motor runs at a rated speed of 1000 RPM when I_L = 4 amps. What is the back EMF V_B in volts when the motor runs at I_L = 6 amps?

Note: Type a 1-decimal number, rounded off to the nearest 0.1

B) How do you know that the compound motor provides good speed control at the no-load condition?

1) The torque speed curve is flat near zero torque. This means that small changes in load do not appreciably change the speed.

2) The torque speed curve is flat near zero torque. This means that large changes in load do not appreciably change the speed.

3) The torque speed curve has a large slope near zero torque. This means that large changes in load lead to very small changes in speed.

4) The compound motor runs at slow speeds when heavily loaded.

5) Items (1) and (4)

C) You are designing a new emergency brake mechanism for an automobile featuring one of the following DC motors. Which one would you choose?

1) Permanent magnet motor

2) Brushless motor

3) Servomotor

4) Compound wound motor

5) Torque motor

(D) Suppose you are building a machine where the timing sequence of two drive axes requires that they operate at precisely the same speed. What type of motor would you select: AC or DC and why?

1) You select identical DC motors because controlling frequency input gives simple and precise speed control

2) You select identical AC motors because highly accurate and reliable AC speed controllers can be bought for very cheap prices

3) You select identical DC motors because controlling voltage input gives simple and precise speed control

4) You select identical AC motors because the variance of torque and speed specs on NEMA specified motors is very small

5) It doesn’t matter whether you select an AC or a DC motor. The cost of supplying accurate speed control for either type of motor is the same.
