It has been reliably determined that variable overhead is a function of direct labour dollars, 2. Engineering and quality control are allocated to products based on their relative proportion of total direct labour dollars. 3. Depreciation is allocated to products based on their relative proportion of total direct labour dollars. The depreciation charge includes $125,000 of R&D costs associated with the knife- gate valve. Because this product is not likely to be launched in the near future, it was decided to expense these costs. 4. Other fixed manufacturing overhead and fixed selling and administrative expenses are allocated to products based on the number of units sold
