Answer:
Estimated manufacturing overhead rate= $0.00327 per engagement revenue.
Step-by-step explanation:
We use normal absorption costing, with corporate overhead costs allocated to engagements using engagement revenues as the allocation base. The engagement expenses for Clarent was $1,219,990. Our estimated total 2011 engagement revenues equaled $373,000,000.
Estimated manufacturing overhead rate= total estimated overhead costs for the period/ total amount of allocation base
Estimated manufacturing overhead rate= 1,219,990/373,000,000= 0.00327 per engagement revenue.
