It is a thermodynamic unit of measurement useful for calculating the amount of energy per mole either released or produced in a reaction. Since enthalpy is derived from pressure, volume, and internal energy, all of which are state functions, enthalpy is also a state function. Delta H, o...
Scenario analysisis one technique for calculating the EV of an investment opportunity. It uses estimated probabilities withmultivariate modelsto examine possible outcomes for a proposed investment. Scenario analysis also helps investors determine whether they are taking on an appropriate level of risk given...
Calculating the Acid-Test Ratio The numerator of the acid-test ratio can be defined in various ways, but the primary consideration should be gaining a realistic view of the company's liquid assets. Cash and cash equivalents should definitely be included, as should short-term investments, such...
