10. Reason for difference in unit cost through both the methods:
 The Overhead cost allocation is different in both the methods
 Each method uses different cost driver
 Standard Unit Cost method uses labour cost to allocate overhead costs
 Revised unit method uses machine hours for allocation of overhead
costs
 Modern method uses each transaction to allocate each overhead
Method Valves Pumps Flow Controllers
Standard Unit Cost 37.56 63.12 56.50
Unit cost based on overhead allocation on transaction basis 37.75 48.83 100.57
Difference (0.19) 14.29 (44.07)
Revised Standard Cost 48.99 58.95 47.96
Unit cost based on overhead allocation on transaction basis 37.75 48.83 100.57
Difference 11.24 10.12 -52.61
Q2

11. Analysis:
 Based on different cost drivers used for allocating overhead costs, unt
cost in each method is different.
 Company should use transaction based method to maintain percentage
gross margin in pumps, they can even further reduce price of pumps
 Transaction method results in losses in sale of flow controller, thus
company need to increase price of Flow Controllers
 Company is not facing competition in Flow Controllers category, hence
they can increase price to achieve target of 35% gross margin
 Destin Brass could also improve process to reduce manufacturing cost
of Flow Controller
 Unit cost of Valve is same for Standard and Transaction bases method,
thus 35% gross margin is achievable
