1 In the past, the Larry’s Lawnmowers Ltd. (LLL) allocated indirect manufacturing costs based on direct labour hours. Recently, management has decided to pilot a system of time-driven activity-based costing to allocate these costs. The division produces two lawnmower models: Lo-cost and Deluxe. The following information has been obtained from the company’s records over the past year:
Direct labour hours incurred
Inspections per lawnmower
Time for each inspection (hrs.)
Lawnmowers packed and shipped per batch
Individual lawnmower packing time (hrs.)
Additional preparation time per batch (hrs.)
LLL employs 245 employees to perform indirect labour functions, rotating among machine setups, final inspections and shipping. Each employee is paid $50,000 per year on average, including benefits. On average, each employee works 1,600 hours per year.
200 automated production machines are leased for $14,000,000 in total each year. Each machine is available for 1,600 hours per year, including set up time. Once a machine is set up, no labour is necessary to oversee it. Machine-related information for the year is as follows:
Machine hours per lawnmower
Set up time per run (hrs.)
