During the nine months ended June 30, 2016, as part of the periodic assessment of useful lives of the intangible assets, the Company determined the indefinite-lived trade names, related to the Risk Management Incorporated and RMI Consulting, Inc. (the “RMI Companies”) acquisitions, were no longer considered to be indefinite. The Company is intending to phase out the use of those trade names in the future. The value of the RMI Companies’ trade names of $1.1 million was recorded in the Commercial Hedging segment. The RMI Companies’ trade names were determined to have a remaining finite useful life of approximately two years. The trade names were not deemed to be impaired, however, the value of the trade names was transferred from the indefinite-lived category to intangible assets subject to amortization and will be amortized over the estimated two year useful life. The Company recorded amortization for the trade names of $0.3 million, within 'depreciation and amortization' on the condensed consolidated income statement, during the nine months ended June 30, 2016. Amortization expense related to intangible assets was $1.2 million and $1.1 million for the nine months ended June 30, 2016 and 2015, respectively. As of June 30, 2016, the estimated future amortization expense was as follows:
(in millions) |
Fiscal 2016 (remaining three months) | $ | 0.4 |
Fiscal 2017 | 1.6 |
Fiscal 2018 | 1.0 |
Fiscal 2019 | 1.0 |
Fiscal 2020 and thereafter | 5.5 |
| $ | 9.5 |
