About these figures
Turnover
Money taken from sales in the year, before any costs.
Profit before tax
What was left after the year’s costs, before corporation tax. A minus figure is a loss.
Net assets, or total equity
Everything the company owns minus everything it owes. A minus figure means it owes more than it owns.
Total assets and total liabilities
Everything the company owns, and everything it owes, on the last day of the year. The gap between them is its net assets.
Cash at bank
Money in the company’s accounts on the last day of the year.
Owed within a year, owed after a year
Debts and bills due in the next twelve months, and those due later.
