This empirical research takes notice of the ratio of break-even point as an important determinant of volatility or uncertainty risk of corporate earnings, and compares the merits and demerits among the eight models designed for the distinction of variable and fixed operating expenses using the total expense amount method and the least square method based on annual or quarterly financial statements. The identified best model is the least square method applied to the 8 quarter periods data from the quarterly financial statements of current and preceding year.
