Net Income Per Unit

Basic net income per unit is derived by dividing net income by the basic weighted average number of units outstanding for each year. Diluted net income per unit is derived by adjusting net income for the assumed dilutive effect of compensatory options (“Net income - diluted”) and dividing by the diluted weighted average number of units outstanding for each year.
