Answer:
liquidity risk
Step-by-step explanation:
Liquidity risk refers to the risk associated with not being able to fulfill short term debts and obligations. Liquid assets are those assets that can be easily converted to cash, e.g. T-bills, publicly traded stocks.
Illiquid assets are those that cannot be easily converted to cash, e.g. real estate property. It doesn't mean that they are a bad investment, but if the company needs cash fast, they need to look somewhere else.
