^a Break-even points are presented as a range when multiple break-even points are relevant to the analysis. Multiple break-even points occur in some of the analyses when the new fixed costs that are incurred when a class reaches its enrollment capacity once again lift the costs above the savings. This relationship is also presented for the face-to-face program in Figure 3.
