Net Operating Income (NOI) A company's operating income after operating expenses are deducted, but before income taxes and interest are deducted. If this is a positive value, it is referred to as net operating income, while a negative value is called a net operating loss (NOL). Investopedia Says: NOI is often viewed as a good measure of company performance. Some believe this figure is less susceptible than other figures to manipulation by management.
