Notes for this questionfrom The statement of financial position for a sole trader
Net assets are all the assets less all the liabilities. Start with non-current assets, add net current assets, then take away non-current liabilities.
For Marlow Cycles the carrying amount of the shop fittings is £8,000, net current assets are £11,000 and the bank loan is £4,000.
Net assets always equal the owner's capital. That is the accounting equation: assets less liabilities equals capital.
