Answer:

In a single index model:

ri - rf = α i + β i (r M - rf ) + e i

Equivalently, using excess returns:

R i = α i + β i R M + e i

The variance of the rate of return can be decomposed into the components:

The variance due to the common market factor

Bi^2stdvm^2

The variance due to firm specific unanticipated events

STDV^2(ei)

In this model

Cov(ri,rj) =BiBjSTDV

The number of parameter estimates is:

n = 60 estimates of the mean E(ri )

n = 60 estimates of the sensitivity coefficient β i

n = 60 estimates of the firm-specific variance σ2(ei )

1 estimate of the market mean E(rM )

1 estimate of the market variance

Therefore, in total, 182 estimates.

The single index model reduces the total number of required estimates from 1,890 to 182. In general, the number of parameter estimates is reduced from:

(n^2 +3n / 2) to (3n+2)

The journal entries are shown below:

1.  Cash A/c Dr $68,000

                  To Common stock                      $5,150

                   To Additional paid-in capital     $62,850

(Being the cash is received)

The common stock value is computed by

= Number of investors × number of shares × par value

= 5 investors  × 103 shares × $10

= $5,150

And, the remaining balance is transferred to additional paid-in capital

2. No journal entry required

3.  Cash A/c Dr $17,000

            To Long term note payable A/c $17,000

(being cash is borrowed for long term payable)

4.  Equipment A/c Dr $18,000

        To Cash A/c                         $1,500

        To Short term note payable $16,500

(Being equipment is purchased for cash and short term note payable)

5.  Short term Notes receivable A/c Dr $1,600

           To Cash                                                       $1,600

(Being cash is paid)

6. Store fixtures A/c Dr $19,000

            To Cash A/c                       $19,000

(being cash is paid for store fixtures)

1. A Contribution Format Income Statement for divisions:

2a. Increase monthly advertising for the West Division by $28,000 to increase its sales by 12%

                                    East          Central        West          Total

Sales                   $412,000  $670,000   $520,000 $1,602,000

Variable exp.         181,280     207,700      166,400      555,380

Contribution

          margin    $230,720    462,300    353,600    1,046,620

Fixed expenses  290,000    332,000     191,000       813,000

Non-Traceable

    Fixed Expenses                                                       338,000

Net operating Income

  (loss)               ($59,280)  $130,300  $162,600   ($104,380)

2b. How much Company's Net Operating Income Increase (Decrease) with the implementation of the above Proposal:

Net operating income before advert = $162,600

Division's net operating income after advert = $160,366

Therefore, the company's net operating loss will increase by $2,234

Explanation:

a) Wingate Company's recent monthly contribution format Income Statement:

Sales                                    $ 1,602,000

Variable expenses                    555,380

Contribution margin               1,046,620

Fixed expenses                        1,151,000

Net operating income (loss) $ (104,380)

b) Division West's Income Statement:

Sales                                 $582,400 ($520,000 x 1.12)

Variable expenses             203,034  ($181,280 x 1.12)

Contribution margin        $379,366

Fixed Expenses                 219,000 ($191,000 + 28,000)

Net Operating Income    $160,366

c) If sales value increases by 12%, the variable expenses will increase proportionately, unless there is an increase in the price, which will ultimately reduce demand, further depressing the sales value.  This is why it is called Variable Cost.  Therefore, a different result will be obtainable if the variable expenses are held constant, contrary to its behavior.
