What are the Loans & assets and Lending tabs on Tax?

Loans & assets is facts for the accountant: who lent to whom, the balance, rate, interest charged and paid, and the 12-month and 9-month dates; and the year's fixed-asset additions with a suggested capital-allowance class and the invoice behind each. 'Loans cannot be read yet' gives the reason. Lending asks which companies could lend spare cash to the trading companies at a market rate, from the same engine. Both are estimates for planning.
