ANSWER
a) The work I will perform in checking supplier‘s statements to the balances on the purchase ledger will include:

 I will assess the system of control in the purchases system and its credibility. This will be based on the results of my tests of control, other investigations an my

experience in previous years. Where the purchases system is reliable, I will check fewer items than if it is unreliable. If I find discrepancies in my audit tests, I will increase the sample of items I check. I will check fewer suppliers‘ statements to the purchase ledger balances if the company perform these checks and corrects discrepancies;
 Generally I will check a larger proportion of suppliers where the balances are large, or where there are a large number of transactions. Where there is no supplier‘s statements for one of these important accounts, I will either contact the supplier to confirm the balance, or ask for a statement at the year end;

 Where the balance on the supplier‘s statement is the same as the purchase ledger balance, I will record this in my working papers and carry out no further work;

 Where there are differences, these could have resulted from either goods in transit, cash in transit or other differences;

 Goods in transit are invoices on the supplier‘s statement, which are not on the client‘s purchases ledger. If these invoices have been included in the accruals, I may perform no further audit tests. However, for large value items, I will check the goods received note (GRN) to ensure they were received before the year-end. If there is no purchase accrual, I will check the date on the GRN. If the date on the GRN is after the year-end, the treatment is correct. However, if it is before the year end there is a cut off error, and management should be advised to include the value of these goods in the current years closing stock and accrual the amount payable;

 For cash in transit, I could check to the next month‘s supplier‘s statement that the cheque was on the supplier‘s sales ledger just before the year-end. An alternative procedure is to check to the bank statement the date the cheque is cleared the bank after the year-end. If there is a significant delay in clearing the cheque, this could indicate that the cheque might have been sent to the supplier after year- end. If this has been happening, the value of these cheques should be added to the year end bank balance and added to creditors at the year end since the payment was made after the year end;

 For other differences, if they are small they can be ignored. However, if they are significant I will discuss them with the client. The year end accounts should include appropriate provision to allow for such differences;

 Based on these tests, I will assess whether they provide sufficient evidence that the trade creditors and purchase accruals are correctly stated at the year-end.

b) The best place to start purchases cut-off test is from goods received notes issued immediately before and after the year- end. Generally, the test should cover a sample of items during the period of two weeks before to two weeks after the year -end.

At the stock take, I should have recorded the last goods received note number issued before the year-end. This will assist in confirming that all items purchased before the year-end are included in the stock and the liability disclosed. I will select a sample of goods received notes issued before the year- end, and follow through to the purchase invoice. For these goods I will check that:

 Either the purchase invoice has been posted to the purchase ledger before the year end or a purchase accrual has been made;

 If there are book stock records, I will check that the goods have been included in the records before the year -end.

There will be a purchases cut off error where either:

 The purchase invoice has not been posted to the purchase ledger before the year end and there is no purchase accrual; or

 The purchase invoice has been posted to the purchase ledger before the year end and there is a purchase accrual at the year end.

For goods received after the year- end, I will select a sample of goods received notes issued after the year-end, and follow through to the purchase invoice. For these goods I will check that:

 Neither the purchase invoice has been posted to the purchase ledger before the year end nor a purchase accrual been made;

 If there are perpetual stock records, I will check that the items received have not been included in the stock records before the year- end.

There will be cut off error where either:
 The purchase invoice has been posted to the purchase ledger before the year end,; or;
 There is a purchase accrual made.
c) I will perform the following work in checking sundry creditors and accruals

 I will assess the level of accruals and the system of control. If the company‘s system of determining accruals is good, I will perform less work than if the controls are weak;

 I will compare this year‘s accruals with the previous year. I will investigate any significant variances e.g. where there was an accrual in the previous year but none this year;

 The wages accrual will be checked to the payroll, the accrual should be equivalent to one weeks gross wages;

 The PAYE should be checked back to the payroll. The accrual should equal the December PAYE payable. I will check to the cash book that the accrual is equal to the payment made to the government in January 2004;

 The VAT creditor will be checked as being the net of out put VAT (VAT on sales) and Input VAT (VAT on purchases). This should be checked against the VAT paid over to the government in January 2004;

 Accrued interest on the bank loan and overdraft will be checked to be bank confirmation received. For loans, the accrued interest should be the product of the amount outstanding, the current interest rate and the time since the last charge;

 Other accruals will be checked to invoices received after the year end;

 I will consider whether there are any circumstances which have arisen during the year which may result in new accruals and I will check if these have been made.
