In preparing the accounts the following conventions and policies had been followed:

(a) The capital maintenance concept is that capital will be maintained if the cost of assets representing the initial monetary investment is recovered against operations.

(b) The concept of profit is that profit for the year is regarded as any gains arising during the year which may be distributed while maintaining the amount of the shareholders’ interest in the company at the beginning of the year.

(c) The measurement unit used is the medium of exchange.

(d) Depreciation of delivery vans is over 4 years using the straight line method.
