Refurbishing PPE

Hello Sir

During the year the company spent $0.75m on refurbishing its stores to improve the customer experience. All of this expenditure has been recognised in the statement of financial position as property, plant and equipment.

The questing asking for the audit risk and response.

I straightly said : There is risk that the PPE and depreciation are overstated and the repairs expense is understated .

And for the response :Review the list of the refurbishing items and expenses and inspecting the related invoices and documents to check the nature of these items if they can be recognized as assets and discussing with the management if these items have been correctly recognized as assets.
If the assets addition is correctly done then matching the assets register with the financial statement figure of PPE which should have included the .75m of addition .
Recalculate the depreciation base on the new total of PPE and check if the depreciation was correctly debited to the profit and loss and the PPE is shown correctly in the financial statement after deducting the accumulated depreciation .

Can you see please how am I handling this audit risk.

Thanks
