Wilson Products uses standard costing. It allocates manufacturing overhead (both variable and fixed) to products on the basis of

standard direct manufacturing labor-hours (DLH). Wilson Products develops its manufacturing overhead rate from the current annual budget. The manufacturing overhead budget for 2014 is based on budgeted output of 672,000 units, requiring 3,360,000 DLH. The company is able to schedule production uniformly throughout the year.
A total of 72,000 output units requiring 321,000 DLH was produced during May 2014. Manufacturing overhead (MOH) costs incurred for May amounted to $ 355,800. The actual costs, compared with the annual budget and 1/12 of the annual budget, are as follows:
