Objective of the workpaper

Allocate the common costs between joint products on a rational and consistent basis after deducting the net realisable value of an immaterial by-product, then determine the cost of inventories under the retail method or the standard cost method and assess how closely the result approximates cost.

Each case that uses this template opens in the mission workspace: data, analysis, calculation, entries, conclusion and review, with your progress saved.

6 instances from the cases: the calculations and entries below are run by the calculation engine.

File and entity
Joint production and retail: by-product and retail method
Case tasks documented here
  • How do you analyse the sawing process and the basis for allocating joint costs?
  • Calculate the net realisable value of the sawdust and the cost of the beams and planks.
  • Can the retail method be used at the store and with which percentage?
  • Calculate the cost of the store's inventories by department and in total.

Inputs

Inputs
  • Production process and products obtained simultaneously (joint products, by-product)

    Text

  • Common costs of the process up to the split-off point, not separately identifiable by product

    Number

    900,000

  • Net realisable value of the immaterial by-product

    Number

    26,000

  • Joint products and allocation basis (one row per product, key PRODUCT_1, PRODUCT_2 or PRODUCT_3)

    Table

    PRODUCT_1 · BEAMS · 600,000 | PRODUCT_2 · PLANKS · 400,000

  • Product whose allocated cost is detailed

    Choice

    Joint product 1

    Joint product 1 / Joint product 2 / Joint product 3

  • Sales value of the inventory of the department

    Number

  • Cost percentage of the sales value (100 − gross margin percentage retained)

    Number

    The gross margin percentage is the one appropriate to the department and takes into account items marked down below their original selling price; an average percentage for each department is often used (para. 22). The figure is a datum of the entity, never set by the standard.

  • Inventories measured at standard cost

    Number

  • Estimated actual cost, to assess how closely the result approximates cost

    Number

  • Evidence obtained and referenced (category, document reference)

Joint products and by-product

Analysis

IAS 2 §14

  • Conditions for allocating joint costs

    Checklist

    • A single process produces more than one product simultaneously (joint products, or a main product and a by-product)
    • Costs of conversion of each product not separately identifiable
    • Allocation on a rational and consistent basis
    • Immaterial by-product measured at net realisable value, deducted from the cost of the main product
4

Techniques for the measurement of cost

Analysis

IAS 2 §21IAS 2 §22

  • Conditions for using the techniques

    Checklist

    • Technique used for convenience, its results approximating cost
    • Standard costs based on normal levels of materials and supplies, labour, efficiency and capacity utilisation
    • Standard costs regularly reviewed and revised where necessary
    • Retail method: large numbers of rapidly changing items with similar margins
    • Gross margin percentage taking into account items marked down

Allocation and cost by technique

Calculations

IAS 2 §14IAS 2 §22

  • Net realisable value of the by-product deducted from the common costs

    Calculation

    26,000

    Common costs of the process up to the split-off point, not separately identifiable by product ; Net realisable value of the immaterial by-product ; Joint products and allocation basis (one row per product, key PRODUCT_1, PRODUCT_2 or PRODUCT_3) ; Product whose allocated cost is detailed

  • Costs allocated to the joint products

    Calculation

    874,000

    Common costs of the process up to the split-off point, not separately identifiable by product ; Net realisable value of the immaterial by-product ; Joint products and allocation basis (one row per product, key PRODUCT_1, PRODUCT_2 or PRODUCT_3) ; Product whose allocated cost is detailed

  • Cost allocated to the product detailed

    Calculation

    524,400

    Common costs of the process up to the split-off point, not separately identifiable by product ; Net realisable value of the immaterial by-product ; Joint products and allocation basis (one row per product, key PRODUCT_1, PRODUCT_2 or PRODUCT_3) ; Product whose allocated cost is detailed

    The engine first deducts the net realisable value of the by-product, then allocates the balance in proportion to the basis entered for each product. The row key must match the product chosen. The basis retained (relative sales value at the split-off point or at completion, for example) is a documented choice of the entity (para. 14). Calculation convention (teaching assumption): when there are several joint products, the net realisable value of the by-product is deducted from the common costs before allocation; para. 14 refers to the cost of the main product.

  • Cost of inventories under the retail method

    Calculation

    Sales value of the inventory of the department ; Cost percentage of the sales value (100 − gross margin percentage retained)

  • Gross margin deducted from the sales value

    Calculation

    Sales value of the inventory of the department ; Cost percentage of the sales value (100 − gross margin percentage retained)

Allocation basis and technique retained

Judgment

IAS 2 §14IAS 2 §21IAS 2 §22

  • Basis for allocating joint costs

    JudgmentRequired

    Relative sales value at the split-off point

    Relative sales value at the split-off point / Relative sales value at completion / Other rational and consistent basis, documented / Not applicable: no joint production

  • Rationale: facts relied on, analysis, alternative rejected

    TextRequired

  • Cost measurement technique retained

    JudgmentRequired

    Actual cost: technique rejected (results not approximating cost, or not used)

    Standard cost method, results approximating cost / Retail method, results approximating cost / Actual cost: technique rejected (results not approximating cost, or not used)

    The standard sets no numerical threshold for approximation: compare the result of the technique with the estimated actual cost and document the assessment (para. 21).

  • Rationale: facts relied on, analysis, alternative rejected
