- Your firm has been the auditor of Caribild Products, a listed company, for a number of years. The engagement partner has asked you to describe the matters you would consider when planning the audit for the year ended 31January 2022. During recent visit to the company you obtained the following information: (a) The management accounts for the 10 months to 30 November 2021 show a revenue of $260 million and profit before tax of $8 million. Assume sales and profits accrue evenly throughout the year. In the year ended 31 January 2021 Caribild Products had sales of $220 million and profit before tax of $16 million. (b) The company installed a new computerised inventory control system which has operated from 1 June 2021. As the inventory control system records inventory movements and current inventory quantities, the company is proposing: (i) To use the inventory quantities on the computer to value the inventory at the year-end (ii) Not to carry out an inventory count at the year-end (c)…arrow_forwardDevelop and implement a complex and scientific project for an organisation of your choice. please include report include the following: Introduction Background research to the project The 5 basic phases in the project management process Project Initiation Project Planning Project Execution Project Monitoring and Controlling Project Closing Conclusionarrow_forwardNot use ai pleasearrow_forward
- Sam's Pet Hotel operates 51 weeks per year, 6 days per week, and uses a continuous review inventory system. It purchases kitty litter for $11.00 per bag. The following information is available about these bags: > Demand 95 bags/week > Order cost $52.00/order > Annual holding cost = 25 percent of cost > Desired cycle-service level = 80 percent >Lead time 4 weeks (24 working days) > Standard deviation of weekly demand = 15 bags > Current on-hand inventory is 320 bags, with no open orders or backorders. a. Suppose that the weekly demand forecast of 95 bags is incorrect and actual demand averages only 75 bags per week. How much higher will total costs be, owing to the distorted EOQ caused by this forecast error? The costs will be $ higher owing to the error in EOQ.

C Consider the following m... As discussed in Section 8.3, the Markowitz model uses the variance of the portfolio as the measure of risk. However, variance includes deviations both below and above the mean return. Semivariance includes only deviations below the mean and is considered by many to be a better measure of risk. (a) Develop a model that minimizes semivariance for the Hauck Financial data given in the file HauckData with a required return of 10%. Assume that the five planning scenarios in the Hauck Financial Services model are equally likely to occur. Hint: Modify model (8.10)-(8.19).
