Asset-liability ratio: it must be lower than 70%, preferably lower than 55%. Asset-liability ratio is the percentage of total liabilities divided by total assets, which is the proportional relationship between total liabilities and total assets. The asset-liability ratio reflects how much of the total assets are financed by borrowing, and can also measure the extent to which enterprises protect the interests of creditors in the liquidation process.

The calculation formula is: asset-liability ratio = (total liabilities/total assets) * 100%.
