Cost Acctg Lecture Inventory Management ABC

 

INVENTORY MANAGEMENT Problem 1: A 1: A television manufacturer buys wooden cabinet from outside suppliers at P400 per set. Total annual needs are 5,000 units at a rate of 20 sets per working data. The following cost data are available: Desired annual returns on inventory investment (10% @ P400) P40 Rent, Insurance, and Taxes per unit P10 Annual Carrying Costs per unit P50 Cost of Ordering P50/order Required: 1.  Using the tabular method and the following order sizes, compute the EOQ of the raw materials: (20, 40, 50, 100, 200, 300) 2.  Using the formula method, compute for the EOQ 3.  Using the computed EOQ, compute the annual ordering costs and annual carrying costs.

Problem 2: Manila uses EOQ logic to determine the order quantity for the nylon fabric its uses in the manufacturing of its flags. Forecasted monthly demand for nylon fabric is for 100,000 yards. The setup costs associated with placing and receiving each nylon fabric order is P50.00. It is estimated that the cost to carry a yard of nylon fabric in inventory for a year is P10.00. Required: 1.  Calculate the nylon fabric EOQ for Manila. 2.  Compute for the annual carrying cost of Manila using its EOQ. 3.  How much is the annual ordering cost of Manila using its EOQ? Problem 3: The following information is available a vailable for Panay Corporation: Annual demand (in units) 100,000 Working days per year 250 days Normal Lead Time in Working days 3 days Required:   Required: 1.  Compute Panay’s Re-order Re-order Point. 2.  Compute Panay’s safety stock level and re-order re -order point if based on experience its maximum lead time is 7 working days.

Problem 4: The current inventory level of a particular raw material is 4,000 units. It was determined that the company 25 days left before it needs to re-order. The annual demand of the raw material is 36,000 and there is 360 production days in a year. Required: 1.  What is the re-order point? 2.  If the normal lead time is 10 days, how many was in the safety stock? 3.  What was the maximum lead time used in determining the level of safety stock?

 

ACTIVITY BASED COSTING (ABC) Activity Based Costing  Costing  - Identifies the causal relationship between the incurrence of cost and activities, determines the underlying driver of activities, establishes cost pools related to individual drivers, develops costing rates, and applies cost to product on the basis of resources consumed (drivers (drivers). ). Definitions:   Activity - is an event, task t ask or unit of work with a specified purpose. Examp Examples les of activities are designing products and setting up machines.   Unit-level activities - These activities are performed for each unit that is i s produced. Some examples are hours of work, inspecting each item, operating a machine and performing a specific assembly task.   Batch-level activities - These activities occur each time a batch is produced. Some examples are machine setup, purchasing, scheduling, materials handling and batch inspection.   Product-sustaining activities - These activities are incurred in order to support the production of a different product from what is currently produced. Examples include product design and engineering changes.   Facility-sustaining activities - These activities are incurred to support production in general, such as security, maintenance, plant management, depreciation of the factory and property taxes.  

Cost object - is anything for f or which costs are accumulated for managerial purposes.

 

Cost driver - is anything (it can be an activity, an event or a volume of something) that causes cost to be incurred each time the driver occurs. Examples of cost drivers are set -ups, moving, number of parts, casting, packaging or handling.

Problem 1: Otto 1: Otto Boutique, a garment business, uses activity based costing and accumulates overhead costs in the following cost pools: 1.  Power 2.  Machining 3.  Direct labor 4.  Materials handling 5.  Ordering 6.  Machine set-ups 7.  Product inspections 8.  Product Design Changes 9.  Testing Routines 10. Plant Plant Supervision 11. Personnel Personnel administration 12. Security Security 13. Engineering Engineering Design Changes 14. Receiving Receiving of Supplies purchased 15. Assembly Assembly Problem 2: Consider the activities that follow. 1. Microsoft: Developing computer coding for a new spreadsheet package. 2. General Mills: Painting the office of a maintenance supervisor at a plant that produces cereal. 3. Mayo Clinic: Examining a new patient. 4. American Airlines: The 90 minutes that a Boeing 757 sits idle on the ground between flights. 5. Office Depot: Moving cases of paper from one location to another in i n the same warehouse. 6. Rolex: Attaching a watch band to the watch’s face.  face.

Required: Categorize each of the activities as either value-added or non-value added for the companies noted. Problem 3: The 3: The company is planning to use activity based costing for its external financial reports. The company’s company ’s activity cost pools and associated data for the t he coming year appear below: below:   Activity Cost Pool

Required:Compute Required: Compute the pre-determined rate for each cost pool. Problem 4: Actual 4: Actual activity for the year was as follows: Activity Cost Pool Actual Activity Machining 5,800 MHs Purchase orders 1,900 Orders Parts management 550 part types Testing 900 Tests General factory 14,700 DLHs Apply overhead using activity based costing and determine the amount of under or over applied overhead and the amount of cost of goods sold for the period. Problem 5: 5: Abby incurs about P860,000 in manufacturing overhead. The company works about 100,000 direct labor hours per month to which the previous controller has allocated overhead costs, so the overhead rate on the average is P8.60. The following information is provided to you: Cost Driver Direct Labor Hours

Amount in Pool P520,000

Amount of Activity 100,000

Number of Batches Engineering Changes Number of Parts Total Overhead Costs

160,000 60,000 120,000 P860,000

360 120 3,200

The controller asks you to analyze two product lines using the existing method of allocating overhead based on DLH, and using activity-based rates. She gives you the following data regarding two product lines. Blue is a bread and butter line that the company makes in large batches, while White is a specialty line that only a few customer buy.
