Note 3. Goodwill

Goodwill is tested for impairment on an annual basis and between annual tests if indicators of potential impairment exist. The date of our annual impairment test is October 1. A change in our reportable segments, more fully described herein in Note 1, resulted in a change in the composition of our reporting units, which is the unit of accounting for goodwill. Accordingly, we reallocated goodwill between our Residential Services, ResCare HomeCare, Education and Training Services and Pharmacy Services reporting units using the relative fair value approach. A summary of changes to goodwill during the nine months ended September 30, 2013 is as follows:
