TACO TRUCK ROUND-UP! Year-End Budget Variance Analysis Your taco truck continues to make tacos, but around June this year, due to preliminary market research results, your truck decided to also make tortillas for distribution to upscale grocery stores. At year-end, your team is performing a budget analysis. For your main stream of income, tacos, you find no significant variances and plan few changes for the upcoming year. However, an in-depth analysis of the tortilla distribution business is warranted, as it is new, and your team needs to decide whether or not to continue with this side of the business. Your truck has two direct-cost categories: direct materials and direct manufacturing labor. Variable manufacturing overhead is allocated to products on the basis of standard direct manufacturing labor-hours. Following is some budget data you compiled earlier in the year: You also have the following information for year-end: Your truck also allocates fixed manufacturing overhead to products on the basis of standard direct manufacturing labor-hours. For the current year, fixed manufacturing overhead was budgeted at $3.00 per direct manufacturing labor-hour. Actual fixed manufacturing overhead incurred during the year was $294,000. Suggested To Do: 1. What is the allocation base used for allocating variable manufacturing overhead? (That is, for how many direct manufacturing labor-hours are you budgeting?) 2. Prepare a variance analysis of variable manufacturing overhead. 3. Discuss the variable OH variances you have calculated and give possible explanations for them. 4. Prepare a variance analysis of fixed manufacturing overhead cost. 5. Is fixed overhead underallocated or overallocated? By what amount
