Net book value (NBV) is the value of an asset as recorded on a company's balance sheet after accounting for accumulated depreciation or amortization. It represents the remaining value of an asset that has not yet been fully depreciated or amortized. NBV is an important measure for financial reporting and analysis.

Net cash flows refer to the difference between the total amount of cash a company receives and the total amount it spends during a specific time period. Positive net cash flows mean the company is generating more cash than it spends, while negative net cash flows mean the company is spending more cash than it generates. Net cash flows are an important measure of a company's financial health and performance.

Net Financial Obligations (NFO) refer to the total amount of financial liabilities a company owes, minus its liquid financial assets.

Net Invested Capital (NIC) refers to the total amount of capital that has been invested in a business by its owners and creditors, net of any cash and cash equivalents.

Net Operating Assets (NOA) refer to the total operating assets of a company minus its operating liabilities.

Net present value (NPV) is a financial measure used to compare the present value of expected cash inflows to the present value of expected cash outflows for an investment or project. It considers the time value of money, meaning that a dollar received in the future is worth less than a dollar received today. If the net present value is positive, it means the investment is expected to be profitable, while a negative net present value indicates that it's not profitable. NPV is an important tool for evaluating investment projects.
