As for DeVry (DV, Financial) (which only the Worldwide Fund owns), our intrinsic value estimate was impaired as we underestimated the extent of the decline of the BTM (Business, Technology, Management) segment. We note, however, that the overwhelming majority of DeVry’s profits come from its healthcare schools (Nursing, Veterinary, and Physicians) where student loan defaults have been negligible.
