(3) GOODWILL

The Company’s goodwill balance was $1,844.1 million and $1,840.2 million as of September 30, 2017 and June 30, 2017, respectively.

The Company’s reporting units are comprised of its strategic product groups (“SPG” or “SPGs”). Effective January 1, 2017, the Company implemented organizational changes which had an impact on the composition of the Company’s SPGs. The change in structure had the impact of consolidating and/or regrouping existing SPGs, disaggregating the legacy Zayo Canada SPG among the existing SPGs and a creating a new Allstream and IP Transit SPG (See Note 12 – Segment Reporting). In connection with the organizational change, goodwill was re-allocated to the Company’s SPG’s on a relative fair value basis. The Company completed an assessment immediately prior to and after the organizational change at the SPG level and determined that it is more likely than not that the fair value of the Company’s reporting units is greater than their carrying amounts.

As of September 30, 2017, the Company’s SPGs were comprised of the following: Fiber Solutions, Zayo Wavelength Services (“Waves”), Zayo IP Transit Services (“IP Transit”), Zayo SONET Services (“SONET”), Zayo Ethernet Services (“Ethernet”), Enterprise Private and Connectivity (“EPIC”), Zayo Cloud Services (“Cloud”), Zayo Colocation (“zColo"), Allstream and Other (primarily Zayo Professional Services).
