Question

Secure

Secure makes plastic security cards that restrict access to certain locations. The standard cost card contains the following in respect of plastic:

0.04 kg at £4 per kg = £0.16

Last month, 100,000 cards were produced and 3,500 kg of plastic was used, costing a total of £18,375.

The production manager (who is also responsible for purchasing) claims that the increase in world oil prices pushed up all plastic prices by 20%, and that a world-wide standard for card readers was introduced which required a slightly larger card (and hence increased the amount of plastic needed) by 5%.

 

Required:

  • Calculate the material price and usage variance, without reference to the manager’s explanation.
  • Split each of the price and usage variances into a planning and an operating part (assuming that production manager’s explanations are reasonable).
