“It is now fairly and widely accepted that conventional cost accounting, distorts
management's view of business through unrepresentative overhead allocation
and inappropriate product costing. This is because the traditional approach usually absorbs
overhead costs across products solely on the basis of the direct labour involved in their
manufacture. As direct labour cost expressed as a proportion of total manufacturing cost
continues to fall, this leads to more an more distortion and misrepresentation of the impact
of particular products on total overhead costs (from Financial Times)

A university offers a range of degree courses. The university's organization structure
consists of three faculties each with a number of teaching departments. In addition, there is
a university administrative/management function and a central services function.
The following cost information is available for the year ended 30 June 2002
a) Occupancy costs total Sh.15,000,000. Such costs are apportioned on the basis of area
used which is:
2. Administration/management costs:
Direct costs: Shs.17,750,000
Indirect costs: an apportionment of occupancy costs.
Direct and indirect costs are charged to degree courses on a percentage basis.
3. Faculty costs:
Direct costs: Shs. 7,000,000.
Indirect costs: an apportionment of occupancy and central services costs.
Direct and indirect costs are charged to teaching departments.
4. Teaching departments:
Direct costs: Shs. 55,250,000.
Indirect cost: an apportionment of occupancy costs and central services costs plus all
faculty costs.
Direct and indirect costs are charged to degree courses on a percentage basis.
5. Central services:
Direct costs: Sh.10,000,000
Indirect costs: an apportionment of occupancy costs.
6. Direct and indirect costs of central services have in previous years been charged to users
on a percentage basis. A study has now been completed which has estimated what user
areas would have paid external suppliers for the same services on an individual basis. For
the year ended 30 June 2002, the apportionment of central services costs is to be
recalculated in a manner which recognizes the cost/savings achieved by using the central
services facilities instead of using external service companies. This is to be done by
apportioning the overall savings to user areas in proportion to their share of the
estimated external costs.
7. The estimated external cost of service provision are as follows:
Central services are apportioned as detailed in (5) above.
The total number of graduates from the university in the year to 30 June 2002 was 2,500.
Required:
a) Prepare a flow diagram which shows the apportionment of costs to user areas. (No value needs to be shown).
b) Calculate the average cost per graduate for the year ended 30 June 2002, for the

Tritech Ltd. has semi-automatic machine process in which a number of tasks are performed.
A system of standard costing and budgetary control is in operation. The process is
controlled by machine attendants who are paid a fixed rate per hour of process time. The
process has recently been reorganized as part of an ongoing total quality management
programme in the company.
The nature of the process is such that the machines incur variable costs even during nonproductive
(idle time) hours. Non-productive hours include time spent on the rework of
products.
(Note: Gross machine hours = productive hours + non-productive hours)
The standard data for the machine process are as follows:
1. Standard non-productive (idle time) hours as a percentage of gross machine hour is
10%.
2. Standard variable machine cost per gross hour is Sh.270.
3. Standard output productivity is 100% that is one standard hour of work is expected in
each productive machine hour.
4. Machine costs are charged to production output at a rate per standard hour sufficient to
absorb the cost of the standard level of non-productive time.
Actual data for the period August to November 2002 have been summarized below:
Required:
a) Calculate the machine variances for productivity, excess idle time and expenditure for
each of the two months of September and October.
b) In order to highlight the trend of variances in the months from August to
November 2002, express each as a percentage term as follows:
i Productivity variance as a percentage of standard cost of production achieved.
ii Excess idle time variance as a percentage of expected idle time.
iii Expenditure variance as a percentage of hours paid for all standard machine cost.
c) Comment on the trend of variances in the August to November period and possible
inter-relationships. Particularly in the context of the total quality management
programme which is being implemented.

New Books Publishers (NBP) Ltd. are planning to introduce a new management accounting text
book. The company's management accountant estimates that the initial distribution
for likely sales is normal with a mean of 20,000 books. In addition, it has been determined that
there is a probability of 0.5 that the likely sales will lie between 16,000 and 24,000 books.
The textbooks will sell for Sh.1,000 per copy but the publishing company pays the author
10% of revenue in royalties while the fixed costs of printing and marketing the book are
calculated at Sh.2.5 million. Using current printing facilities, the variable production costs are
Sh.400 per book, however the NBP Ltd. Has the option of hiring a special machine for
Sh.1.4 million which will reduce the variable production costs to Sh.250 per book.

Madoadoa Limited is a multi-division manufacturing company. The manufacture of M101.
One of the company‟s finished products involves two divisions; Mwanzo and
Mwisho.Mwanzo division manufactures the chassis for M101 and transfers it to Mwisho
division where it is reworked, fitted and assembled into the finished product. The two
divisions are housed in the same building whose lease is due to expire in two years‟ time.
Data on the operations of the two divisions for the year just ended is as follows:
Mr. Makini, the general manager of Mwisho division, has been considering the possibility of
sourcing the chassis from outside suppliers. He has received a quotation from Samawati
Ltd., a competitor of Mwanzo division offering to supply a minimum of 30,000 and a
maximum of 40,000 units of chassis per year for two years with adequate guarantees as to
quality and continuity of suppliers. The unit price would be Sh.22,000. Mr.Makini is of the
opinion that his division should be allowed to take all its requirement (30,000 units per year)
of chassis from Samawati Ltd., unless Mwanzo division agrees to cut the unit transfer price
to Sh.22,000. He suggests that if Mwanzo division cannot reduce the price it would be better
for it to cease operations and the space it now occupies be taken up by Mwisho division,
which is currently seeking extra warehouse space.
The summarized profit and loss accounts of the divisions for the past year ended 31
October 2001 is as follows:
You have been asked to investigate and advise on Makini‟s proposal. You have
gathered the following additional information:
The limitation of the proposed contract with Samawati Ltd. To a two-year period would be
agreeable to Madoadoa Ltd. As the lease for the factory is unlikely to be renewed in two years‟
time and there is no wish to enter into firm commitments beyond that date. If
Mwanzo division is closed, most of the work force could be productively absorbed by other
divisions of Madoadoa Ltd., which operate in the vicinity at no additional cost to those
divisions.
The manager of Mwanzo division complains that his division has to bear exceptionally
heavy depreciation charges and fixed overheads (including central office charges) which are
beyond his control. Without these expenses, he believes that Mwanzo division could match
price quoted by Samawati Ltd., and still make a reasonable profit. He also believes that with
a price of Sh.22,000, it should be possible to operate at full capacity, selling 25% of the
output in the open market. The additional output would increase the direct materials cost
and variable overhead proportionately but he estimates that the total direct labour cost
would only increase by 10%.
The plant used by Mwanzo division has a book value of Sh.150,000,000. Its current resale is
probably Sh.50,000,000. in two years it is estimated that it will have negligible value.
The storage space required by Mwisho division will probably cost Sh.10,000,000 per annum if rented.
Mwanzo division has in stock sufficient raw material for nine months‟ production if
production is continued at the same level as he has achieved last year. If this raw material is
sold off (following the decision to close Mwanzo division), it would probably fetch 25% of
its cost.
Required:
a) Mwanzo division‟s combined profit and loss account for the ensuring two-year
period on the assumption that the division continues to operate after reducing its
transfer price to Sh.22,000 and operating at full capacity as expected.
b) A statement of costs and benefits to Madoadoa Ltd. If a decision to adopt the
proposal made by Mr. Makini rather than the plan put forward by the manager of
Mwanzo division is taken.

Kamau and Njoroge are two cousins specializing in hawking business along River
road. Kamau specializes in second hand shirts while Njoroge specializes in cheap
electronic goods. However, sales have been decreasing partly due to the harsh
economic condition in Kenya and partly due to restrictions by the City Council.
Each of the cousins is considering expanding to include in their lines of business,
items on which their rivals now have a monopoly. Each knows that the other is
considering this expansion and this influences each of their decisions.
Kamau figures out that if he does not expand his business and his cousin does, it will
hurt his trade by Sh.500 of profit per day. If neither of them expands inventory to
include the extra product, Kamau thinks it will boost his net profit by Sh.500 per day
due to his superior location. If he expands and his cousin does also, he believes the
combination of location and expanded inventory will increase his profits by Sh.1,000
per day. However, if he alone expands and his cousin does not, this will result in no
net increase in business.
