Such a case is illustrated in Figure V. EF is again the market odds line. A separating equilibrium exists (&H, -L). Suppose that a firm offered the two contracts, aHf and aLf; aH' makes a loss, aLf makes a profit. High-risk types prefer aH' to &H, and low-risk types prefer aL' to L. These two contracts, if offered by a single firm together, do not make losses. The profits from aLt subsidize the losses of aHf. Thus, (KHf, aLI) upsets the equilibrium (&H, -L).
