Advanced Cost Management

Problem 1 - Tessmer Manufacturing Company produces inventory in a highly automated assembly plant in Olathe, KS.  The automated system is in its first year of operation and management is still unsure of the best way to estimate the overhead costs of operations for budgetary purposes.  For the first six months of operation, the following data was collected:

                                           Machine-hours      Kilowatt-hours     Total Overhead Costs

        January                              3,800                  4,520,000                       $138,000

        February                             3,650                  4,340,000                        136,800

        March                                3,900                   4,500,000                       139,200

        April                                  3,300                   4,290,000                       136,800

        May                                  3,250                   4,200,000                       126,000

        June                                 3,100                   4,120,000                       120,000

Question 1: Use the high-low method to determine the estimating cost function with machine-hours as the cost driver.  (five points)

Question 2: Use the high-low method to determine the estimating cost function with kilowatt-hours as the cost driver.  (five points)

Question 3:  For July, the company ran the machines for 3,000 hours and used 4,000,000 kilowatt-hours of power.  The overhead costs totaled $114,000.  Which cost driver was the best predictor for July?  (five points)

Problem 2 - Louder Company manufactures part MNO used in several of its truck models.  A total of 10,000 units are produced each year with production costs as follows:

Direct materials                                 $ 45,000

Direct manufacturing labor                     15,000

Variable support costs                          35,000

Fixed support costs                              25,000

Total costs                                      $120,000

Louder Company has the option of purchasing part MNO from an outside supplier at $11.20 per unit.  If MNO is outsourced, 40% of the fixed costs cannot be immediately converted to other uses.

Question 1:  What amount of the MNO production costs is avoidable? (five points) 

Question 2:  Should the company outsource MNO?  Why or why not?  (five points)


Question 3: What other items should the company consider before outsourcing any of the parts it manufactures?  (five points)
