Final answer:
When a business has a negative net income, it is called a loss. This happens when the cost of goods sold and expenses exceed sales revenue.
Step-by-step explanation:
When a business has a negative net income, it is referred to as a loss. This occurs when the cost of goods sold and expenses are higher than the sales revenue.
