Lock Co makes a single product – a lock – and uses marginal costing. The standard cost card for one unit is as follows: A junior member of the accounts team produced the following variance statement for the month of May. Lock Co used 3,648 kg of materials in the period and the labour force worked – and was paid for – 1,824 hours. Until now, Lock Co has had a market share of 25%. In the month of May, however, the market faced an unexpected 10% decline in the demand for locks.
