You are the audit manager of a medium-sized firm and have just received a package from Rachel Jones, the financial controller of Telechubbies Ltd, a toy manufacturer. This is your firm's first year as auditor of Telechubbies. The information contained in the statement of financial position and income statement was prepared for a board meeting and Rachel felt it might be useful to you in preparation of the forthcoming audit for the year ended 31 December 2021.

During a brief telephone call with Rachel, you made the following notes:

1. One of the conditions of the long-term loan is that the company is not to exceed a debt-to- equity ratio of 2:1 at any time. The loan is reviewed each year on 31 December.
2. Provision against inventory obsolescence is provided for at a flat rate of 10%. The amount provided in previous years was 20%. Rachel said that the company believes it has been overly conservative in previous years and 5% is a more realistic level, given the nature of its products.
3. The long-term loan receivable is from a company involved in the development and production of computer software. It is owned by one of the directors.
