This document discusses different types of leverage used in business - operating, financial, and combined leverage. Operating leverage is related to fixed operating costs and how they magnify changes in sales on earnings. Financial leverage uses fixed financing costs to magnify the effect on earnings per share. Combined leverage is the product of operating and financial leverage. Degrees of leverage are defined to quantify the effects. Indifference points are discussed as the earnings level where leveraged vs unleveraged financing plans yield equal shareholder returns. Analysis of earnings-per-share for different financing options is based on expected earnings levels relative to the indifference point.
