Similarly, in departmental cost or profit reports the fixed costs of overhead or ser-
vice departments may be allocated to production departments as an integral part of
the production departments’ costs or else segregated in some form.
Required:
Describe absorption and marginal (or direct or variable) costing and outline the

1. Marginal costing provides for the complete segregation of fixed costs, thus         variable costing
     facilitating closer control of production costs.                                  system
2. It eliminates the distortion of interim profit statements which occur when there
     are seasonal fluctuations in sales volume although production is at a fairly
     constant level.
3. It results in cost information which is more helpful in determining the sales
     policy necessary to maximise profits.
From the accounting records the following figures were extracted: Standard cost

The budgeted fixed factory overhead for Synchrodot Ltd is £180 000 (per quarter)
for product 1 and £480 000 (per quarter) for product 2. This apportionment to prod-
uct lines is achieved by using a variety of ‘appropriate’ bases for individual expense
categories, e.g. floor space for rates, number of workstaff for supervisory salaries
etc. The fixed overhead is absorbed into production using practical capacity as the
basis and any volume variance is written off (or credited) to the Profit and Loss
Account in the quarter in which it occurs. Any planned volume variance in the
quarterly budgets is dealt with similarly. The practical capacity per quarter is 30 000
units for product 1 and 60 000 units for product 2.
  At the March board meeting the draft budgeted income statement for the
April/May/June quarter is presented for consideration. This shows the following:

The statement causes consternation at the board meeting because it seems to show
that product 2 contributes much more profit than product 1 and yet this has not
previously been apparent.

                      The Sales Director is perplexed and he points out that the budgeted sales pro-
                    gramme for the forthcoming quarter is identical with that accepted for the current
                    quarter (January/February/March) and yet the budget for the current quarter
                    shows a budgeted profit of £120 000 for each product line and the actual results
                    seem to be in line with the budget.
                      The Production Director emphasises that identical assumptions, as to unit variable
                    costs, selling prices and manufacturing efficiency, underlie both budgets but there has
                    been a change in the budgeted production pattern. He produces the following table:
                      Budgeted Production                     Product 1                 Product 2

                    He urges that the company’s budgeting procedures be overhauled as he can see no
                    reason why the quarter’s profit should be £24 000 up on the previous quarter and
                    why the net profit for product 1 should fall from £4.00 to £2.80 per unit sold,
                    whereas, for product 2 it should rise from £2.11 to £3.16.
                    You are required:
                    (a) To reconstruct the company’s budget for the January/February/March quarter.

                    (b) To restate the budgets (for both quarters) using standard marginal cost as the
                        stock valuation basis.                                                  (8 marks)
                    (c) To comment on the queries raised by the Sales Director and the Production
                        Director and on the varying profit figures disclosed by the alternative budgets.
