$13-33$ Flexible budgets, integrated variance analysis. $($CMA$,$ adapted$)$ Clarke

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

basis of standard direct manufacturing labor$-$hours $($DLH$).$ Clarke develops its manufacturing overhead rate from

the current annual budget. The manufacturing overhead budget for $2013$ is based on budgeted output of $636,000$

units, requiring $3,816,000DLH.$ The company is able to schedule production uniformly throughout the year.

A total of $74,000$ output units requiring $318,000DLH$ was produced during May $2013.$ Manufacturing

overhead $($MOH$)$ costs incurred for May amounted to $$340,200.$ The actual costs, compared with the annual

budget and $\frac{1}{12}$ of the annual budget, are:
