a) State and explain which accounting concepts are applicable or should be followed in the following situations, giving your reasons for the concept chosen: i. A company which depends entirely on imported raw materials has been operating on a large overdraft. The non-availability of foreign exchange has made importations difficult and the bankers have also refused to consider further overdraft facilities. The directors are therefore concerned about the future success of the company and have asked the accountant to estimate how much the company's assets are worth. (2 Marks)
