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.

Net tangible asset value (NTAV) is a financial measure used to determine the net value of a company's physical assets, such as property and equipment, after subtracting liabilities and intangible assets. It represents the value of a company's assets that can be easily liquidated. A high NTAV indicates that a company has a strong asset base, while a low NTAV may indicate that a company is heavily reliant on intangible assets or has a high level of debt. This measure is important to assess a company's financial health and performance.

Non-amortizable intangibles are assets that cannot be gradually written off over time for accounting purposes. Non-amortizable intangibles maintain their value indefinitely and are not subject to systematic depreciation or amortization.

Non-controlling interest (NCI), also known as minority interest, refers to the portion of a subsidiary company’s equity that is not owned by the parent company. In other words, it represents the shares in a subsidiary that are held by outside investors.

Non-GAAP measures are financial metrics that do not conform to Generally Accepted Accounting Principles (GAAP). Companies use these alternative performance measures to provide a clearer picture of their financial performance, excluding items they believe are non-recurring, non-cash, or not reflective of their core operations.

Nonoperating assets are assets that are not used to generate revenue in a company's primary business operations. They are held for investment purposes or other strategic reasons, like providing liquidity or diversifying a company's portfolio. Examples include investments in stocks, bonds, and real estate. Nonoperating assets are reported separately from operating assets and can affect a company's financial performance and valuation. They are important to monitor for assessing a company's overall financial health and performance.
