New study design in 2019 - not sure how applicable what I'm saying is, but I think it's still valid advice.
Don't put the characteristics/assumptions in brackets, its better to just say them directly.
For example: The $3000 spent on chairs should be recorded within the business records, because it was a transaction between the business and another firm, where the firm has gained an asset. This information is useful for decision making, hence recording the transaction upholds relevance.
The $1000 spent on the office desk for his family home on 15 June, should not be recorded in the firm's books, as it is a transaction by the owner, which is not relevant to the business, as the owner and the business are separate as per the entity principle. Recording this transaction in the firm's books would breach the entity principle, and the information would not be useful for decision making, breaching relevance.
