We are evaluating a project that costs $1.68 million, has a six-year life, and has no salvage value. Assume that depreciation is

Answer:

Best-Case Worst-Case

NPV NPV

PV of cash inflows $2,897,706 $3,187,477

PV of project cost $1,680,000 $1,848,000 ($1,680,000 * 1.1)

NPV $1,217,706 $1,339,477

Explanation:

a) Data and Calculations:

Initial project cost = $1.68 million

Project's estimated life = 6 years

Salvage value = $0

Depreciation expense = $280,000 ($1.68 million/6)

Income Statement:

Sales revenue (90,000 * $37.95) = $3,415,500

Cost of goods sold:

Variable cost (90,000 * $23.20) = 2,088,000

Gross profit = $1,327,500

Fixed costs = 815,000

Income before tax = $512,500

Income tax (21% of $512,500) = 107,625

Net income = $404,875

Add depreciation expense 280,000

Annual cash inflows = $684,875

PV annuity factor for 6 years at 11% = 4.231

PV of annual cash inflows of $684,875= $2,897,706 ($684,875 * 4.231)

Annual cash inflows = $753,363 ($684,875 * 1.1)

PV of annual cash inflows of $753,363 = $3,187,477 ($753,363 * 4.231)

Stock Y has a beta of 1.2 and an expected return of 12.1%. Stock Z had a beta of 0.8 and an expected return of 7.85%. The risk-f

levacccp [35]

Answer:

Since the expected return and required return are different for both Stock X and Z, we say that they are not correctly priced

Explanation:

To determine whether or not the stocks are correctly priced ,

we have to compare the required return and the expected return on each of them.

Required return = Rf +β (Rm-Rf)

Note that Rm-Rf is also known as market risk premium

Stock Y Stock Z

Required return 2.4% + 1.2(7.2%) 2.4% + 0.8(7.2%)

= 11% = 8.2%

Expected return 12.1% 7.85%

Since the expected return and required return are different for both Stock X and Z, we say that they are not correctly priced

Purchases *16,800

Requisitions 18,400

Ending 6,600

We solve for purchases:

6,600 + 18,400 - 8,200 = 16,800

WIP Inventory

Beginning 7,700

Materials 18,400

Labor 13,700

Overhead 8,200

Transferred Out 39,700*

Ending 8,300

The transferred-out from WIP inventory is the transferred-in for Finished Goods

Sergio [31]

Answer:

P0 = $51.9956 rounded off to $52.00

Explanation:

The two stage growth model of DDM will be used to calculate the price of a stock whose dividends are expected to grow over time with two different growth rates. The DDM values a stock based on the present value of the expected future dividends from the stock.

The formula for price of the stock today under this model is,

P0 = D0 * (1+g1) / (1+r) + D0 * (1+g1)^2 / (1+r)^2 + ... + D0 * (1+g1)^n / (1+r)^n + [ (D0 * (1+g1)^n * (1+g2) / (r - g2)) / (1+r)^n ]

Where,

D0 is the dividend today or most recently paid dividend

g1 is the initial growth rate which is 20%

g2 is the constant growth rate which is 8%

r is the required rate of return

P0 = 2.5 * (1+0.2) / (1+0.15) + 2.5 * (1+0.2)^2 / (1+0.15)^2 +

2.5 * (1+0.2)^3 / (1+0.15)^3 +

[(2.5 * (1+0.2)^3 * (1+0.08) / (0.15 - 0.08) / (1+0.15)^3)

P0 = $51.9956 rounded off to $52.00
