To accommodate surface mount technology, SMT, a completely new set of components was needed. New SMT outlines were required, and often the same components, e.g. ICs were sold in both traditional leaded packages and SMT packages.
The most well known financial leverage ratio is the debt-to-equity ratio. It is expressed as: Total debt / Total Equity. For example, if a company has $10M in debt and $20M in equity, it has a debt-to-equity ratio of 0.50 = ($10M/$20M).
The debt to equity ratio is a particularly important financial leverage ratio, in that it is used to calculate levered beta, which is sometimes referred to as equity beta. As the number of formulas, as well as variables, required to complete a specific formula increase, the more variance in results occur due to errors.
