Intangible Assets Estimated Fair Value Description     The impairment review completed in the fourth quarter of fiscal year 2014 indicated the fair value exceeded the carrying value of the DeVry University reporting unit by 24%. Due to the effects of continually declining enrollments, this excess margin has been rapidly declining in recent periods. A 10% decrease in the fiscal year 2015 projected operating income used in this analysis would result in no less than a 21% premium of fair value over carrying value.
