A) MarketB) LiquidityC) BusinessD) Inflation

Answers

Answer:

B) Liquidity

Explanation:

Liquidity is the ability of quickly buy or sell a stock without any price change.

Liquidity in a small-capitalization stock that has low trading volume is generally low that causes a problem for traders.

Hence, the correct answer is B) Liquidity.

The production budget shows expected unit sales of 40000. Beginning finished goods units are 3800. Required production units are 41600. What are the desired ending finished goods units

Answers

Answer:

desired ending inventory= 5,400 units

Explanation:

Giving the following information:

Sales= 40,000 units

Beginning finished goods= 3,800 units

Production= 41,600 units

To calculate the desired ending inventory, we need to use the following formula:

Production= sales + desired ending inventory - beginning inventory

41,600= 40,000 + desired ending inventory - 3,800

41,600 + 3,800 - 40,000= desired ending inventory

desired ending inventory= 5,400 units

The stock pays a dividend of $2 per year and its price is $80. If the market return is 7% and the risk-free rate is 1%, what is the stock beta? A. 0.4 B. 0.5 C. 0.25 D. 0.1

Answers

Answer:

The beta of the stock is 0.25 and option C is the correct answer.

Explanation:

The current price of a stock which pays a constant dividend can be determined using the zero growth dividend model of DDM. The formula to calculate the price under this model is,

P0 = Dividend / r

Where,

r is the required rate of return on the stock

As we already know the value of P0 and Dividend, we can plug in these values in the formula and calculate the value of r.

80 = 2 / r

80 * r = 2

r = 2 / 80

r = 2.5% or 0.025

The required rate of return can also be calculated using the CAPM equation. The formula for r under CAPM is,

r = rRF + Beta * (rM - rRF)

Where,

rRF is the risk free raterM is the return on market

To calculate beta, we will input the values for r, rRf and rM in the CAPM equation.

Let beta be x.

0.025 = 0.01 + x * (0.07 - 0.01)

0.025 - 0.01 = x * 0.06

0.015 / 0.06 = x

x = 0.25

Thus, beta is 0.25

What is the payback period for each project?

Answers

Answer:

Project A 2.22 years

Project B 3.05 years

Explanation:

Calculation for the payback period for each project

Project A

First step is to calculate for the amount received in 2 years

Amount received=$18,500+24,800

Amount received =$43,300

Second step is to calculate for the amount not received

Amount not received =$48,000-$43,300

Amount not received =$4,700

Third step is to find out when the remaining amount will be received.

=$4,700/$20,500

=$0.22 years

Last step

Payback period=2+0.22 years

Payback period =2.22 years

The payback period for project A will be 2.22 years

Project B

First step is to calculate for the amount received in 3 years

Amount received=$20,500+$25,500+$33,500

Amount received =$79,500

Second step is to calculate for the amount not received

Amount not received =$93,000-$79,500

Amount not received =$13,500

Third step is to find out when the remaining amount will be received.

=$13,500/$247,000

=$0.05 years

Last step

Payback period=3+0.05 years

Payback period =3.05years

The payback period for project B will be 3.05 years

Knowledge Check 01 On December 31, 2019, Wintergreen, Inc., issued $150,000 of 7 percent, 10-year bonds at a discount of $10,125. The bonds pay interest semiannually. Wintergreen uses the straight-line bond amortization method. The entry to record each interest payment includes a debit to Bond Interest Expense for $5,756, a credit to Discount on Bonds Payable for $506, and a credit to Cash for $5,250. At December 31, 2020, the carrying value of the bonds will equal _____.

Answers

Answer:

Carrying value of bond = $140,887 .50

Explanation:

Balance in discount on bonds account as on Dec 31, 2019 = Total discount on bonds - amortized discount on 30 June, 2019 - discount amortized on Dec 31, 2019

= $10,125 - $506.25 -$506.25

= $9,112.50

Carrying value of the bond = Face value of bond - Balance in discount on bonds account.

= $150,000 - $9,112.50

= $140,887 .50

Note:

Amortization of discount on bonds = Total discount on bond / total number of interest payments

= $10125/(10×2)

= $10125/20

= $506.25

Which of the following is the best description of the product life cycle of this product?

a. Long, level beginning, and rapid ascent
b. High initial sales followed by slow decline
c. High introductory sales followed by rapid decline
d. Rapid growth followed by rapid decline
e. Moderately slow introduction, followed by modest growth, gradually leveling off

Answers

Answer: Moderately slow introduction, followed by modest growth, gradually leveling off

Explanation:

The product life cycle is the time a product takes from the introduction stage to the decline stage when it's off the market.

Based on the above scenario, the product life cycle of this product will be moderately slow introduction, followed by modest growth, gradually leveling.

This is because since it's a new product, there will be a slow introduction as people will just be getting used to the product, then as customers begin to buy the product and it's brand becomes known, there'll be a modest growth before it levels off.

changed its estimates to a total useful life of 5 years with a salvage value of $81000. What is 2021 depreciation expense?

Answers

Answer:  $162,000

Explanation:

The depreciation expense for the first 3 years up till 2021 is;

= (Cost - Salvage value)/Useful life

= ( 579,000 - 57,000) / 9

= $58,000

In 2021, the Net book value was;

= 579,000 - ( 58,000 * 3)

= 579,000 - 174,000

= $405,000

Useful life has been changed to 5 years. 3 years have already elapsed left with 2.

New salvage value is $81,000.

= (NBV - Salvage Value) / Useful life

= (405,000 - 81,000) / 2

= $162,000

Answers

Answer: C. $0

Explanation:

When including initial costs in a project's cash-flow, the relevant costs are those that henceforth will be spent on the project. Sunk costs are not to be included because they have already been incurred and cannot be recovered.

Research and Development costs have already been incurred and so are sunk costs. Hence they are not to be included in the initial cash-flow for the project.

Suppose an industry earns a rate of return of 10%, which is twice as high as that of competitive industries, 5%. How much is the price overcharge of that industry, if its capital is valued at half its annual revenue

Answers

Answer:

Let us assume that both the industries are having an investment of $100,000

The profit of the given industry which is having 10% rate of return will be $100,000 * 10% = $10,000

The other industry which is having the Rate of return of 5% will earn a profit of $100,000 * 5% = $5000.

As the capital is just half of the revenue, it signifies that the total revenue will be $200,000 . So the same value of $10,000 will be 5% of the total revenue.  On the other hand, $5,000 would be 2.5% of total revenue.

Thus, the first stated industry will charge 2.5% more than the other industry.

Potential GDP of an economy is $12 billion. Real (Actual) GDP is $20 Billion. Marginal propensity to consume is 0.75. What level of Government spending is required to achieve Full employment

Answers

Answer:

Government spending required  = $2 billion

Explanation:

The required amount of GDP to achieve the full employment GDP =

Potential GDP - Actual

that is 20 - 12 = $8 billion.

But note that a government spending of less than $8 billion would be required to achieve an increase of 8 billion in real GDP. This is so because of   expenditure multiplier effect.

The expenditure multiplier is the amount by which the aggregate output would increase with an increase in any of the expenditure components.

It is calculated as follows;

Multiplier = 1/(1-MPC)

For this question ,

Expenditure multiplier = 1/(1-0.75) = 4

This implies that $1 change in any of the aggregate expenditure would lead a $4 worth of change in GDP.

Government spending required  is determined as

Desired change in real GDP/expenditure multiplier

= $8 billion/4 = $2 billion

Government spending required  = $2 billion

Company XYZ's trial balance summarizes all the general ledger account balances with the assets and expenses on the debit side and the liabilities, equity, and income on the credit side.  It is extracted from the general ledger for all accounts that do not have equal debit and credit sides.  It is one of the ways to ensure that proper double entry system of bookkeeping has been followed.  That the two sides are in balance does not mean that the trial balance or the general ledger from which it is prepared is error-free.  It simply means that the two sides agree in total.  XYZ can prepare the trial balance at any time, not necessarily at the end of the period.

A stock is selling today for $40 per share. At the end of the year, it pays a dividend of $2 per share and sells for $44. a. What is the total rate of return on the stock?

Answers

Answer:

The total rate of return on the stock is 14%.

Explanation:

The sources of income from a stock are dividends and increase in its value. Therefore, the total rate of return on stock is calculated by dividing the addition of appreciation in the of the stock and dividends paid by the original stock price.

Therefore, the total rate of return on the stock can be calculated using the following formula:

Total rate of return = [(P1 - Po) + D] / Po .......................... (1)

Where;

P1 = Ending stock price = $44

Po = Initial stock price = $40

D = Dividend paid = $2

Substituting the values into equation (1), we have:

Total rate of return = [(44 - 40) + 2] / 44

Total rate of return = [4 + 2] / 44

Total rate of return = 6 / 44

Total rate of return = 0.14, or 14%
