Before negotiating a long-term construction contract, build- ing contractors must carefully estimate the total cost of completin

g the project. Benzion Barlev of New York University proposed a model for total cost of a long-term contract based on the normal distribution(Journal of Business Finance and Accounting, July 1995). For one particular construction contract, Barlev assumed total cost, x, to be normally distributed with mean $850,000 and standard deviation $170,000. The revenue, R, promised to the contractor is $1,00,000.
Required:
a. The contract will be profitable if revenue exceeds total cost. What is the probability that the co ntract will be profitable for the contractor?
b. What is the probability that the project will result in a loss for the contractor?
c. Suppose the contractor has the opportunity to renegotiate the contract. What value of R should the contractor strive for in order to have a .99 probability of making a profit?

Answer:

<h3>Benzion Barlev of New York University</h3>

NEGOTIATION OF A LONG-TERM CONSTRUCTION CONTRACT

a. The probability that the contract will be profitable for the contractor is:

= 81%

b. The probability that the project will result in a loss for the contractor is:

= 19%

c. The value of R that the contractor should strive for in order to have a .99 probability of making a profit is:

= $1,246,100.

Explanation:

a) Data and Calculations:

Mean total cost (x) = $850,000

Standard deviation = $170,000

Revenue = $1,000,000

Probability of being profitable = (R - x)/std deviation

= ($1,000,000 - $850,000)/$170,000

= $150,000/$170,000

= 0.882

From Z table, 0.882 = 0.81057 = 81%

Probability of loss = 19% (100 - 81%)

To have a 99% (0.99) probability of making a profit, Z value = 2.33 from the Z table:

(R - x)/std deviation = 2.33

(R - x) = 2.33 * $170,000

= $396,100

(R - $850,000) = $396,100

R = $396,100 + $850,000

R = $1,246,100

Sophie [7]

Answer:

Job 334 total cost:    $  8,400

Unit cost: 8,400 / 200 = $  42

Explanation:

Total cost: Material + Labor + Overhead

Material: 5,000

Labor:     2,400

<u></u>

<u>Overhead:</u>

\frac{Cost\: Of \:Manufacturing \:Overhead}{Cost \:Driver}= Overhead \:Rate

We distribute the expected cost over the expected base:

expected cost: 100,000

cost driver: 40,000 labor hours

cost per hour: 100,000 / 40,000 = <u>2.5 predetermined overhead</u>

Now we multiply this rate by the hours of the job to know Applied Overhead:

job labor hours x overhead rate:

Job #334 had 2,400 labor cost / $6 rate per hour = 400 hours

400 x 2.5 = 1,000

Total cost: 5,000 + 2,400 + 1,000 = 8,400
