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).
Leverage ratios measure how leveraged a company is, and a company's degree of leverage (that is, its debt load) is often a measure of risk. When the debt ratio is high, for example, the company has a lot of debt relative to its assets.
