model ans:
For a sample of individual product lines shown as held at the year end in the inventory valuation report, agree the quantities to the year-end inventory count schedule.
Agree the cost of a sample of individual product lines, including Remy Gusteau products recorded in the inventory valuation report to purchase invoices.
Compare actual sales per month of Remy Gusteau products to budgeted sales per month since February to establish how much lower actual sales are than expected sales and discuss with management.
Select a sample of items recorded in inventory, including Remy Gusteau products, and review post-year-end sales invoices compared to cost to ascertain if net realisable value (NRV) is above cost or if an adjustment is required.
If Cookit Co has not reduced its prices, perform an internet search to establish the prices currently charged by Cookit Co’s competitors for Remy Gusteau products to establish if sales are likely to occur at the prices charged by Cookit Co.
Calculate the inventory holding period and compare with the prior year. Investigate any significant differences.
Review the aged inventory report and identify any slow-moving goods, discuss with management whether an allowance in respect of these has been made or is required.
Follow up any damaged or obsolete items noted by the auditor during the inventory count, discuss with management whether the value of these goods has been adjusted.
Review board minutes for discussion on the impact of falling demand for Remy Gusteau products and whether an allowance to reduce the inventory to NRV is required.
Discuss with management whether they believe that the cost of Remy Gusteau products exceeds NRV and whether an allowance against inventory is necessary.
