Securities are negotiable and exchangeable instruments that represent a financial value, and they are categorized as either debt securities, such as bonds and debentures issued by governments and corporations, or equity securities, such as common and preferred stocks, which reflect a proof of partial ownership or right in a corporation.

TAG-Value provides the valuation of a broad range of securities, which includes equity, equity and interstate options, swaps, treasuries, corporate and government bonds, mortgage-backed securities, collateralized mortgage obligations, credit derivative swaps, and many more.

TAG-Value uses diagnostic tools for valuing securities, applying a series of mathematical relationships and financial models to determine the price at which a security should be exchanged.
