| Electrical Infrastructure |  | Oil Gas & Chemical |  | Storage Solutions |  | Industrial |  | Total
| (In thousands)
Net balance at June 30, 2017 | $ | 42,152 |  |  | $ | 33,604 |  |  | $ | 16,764 |  |  | $ | 20,981 |  |  | $ | 113,501 |
Translation adjustment (1) | 234 |  |  | — |  |  | 81 |  |  | 44 |  |  | 359 |
Net balance at September 30, 2017 | $ | 42,386 |  |  | $ | 33,604 |  |  | $ | 16,845 |  |  | $ | 21,025 |  |  | $ | 113,860 |
(1) | The translation adjustments relate to the periodic translation of Canadian Dollar and South Korean Won denominated goodwill recorded as a part of prior acquisitions in Canada and South Korea, in which the local currency was determined to be the functional currency.
We performed our annual goodwill impairment test as of May 31, 2017, which resulted in no impairment. However, the aggregate difference between the fair values of our reporting units and their carrying amounts decreased significantly since the previous year's test as a result of market conditions at that time. The fair value of one reporting unit (carrying value of goodwill of $8.0 million) only exceeded its carrying amount by 9%. The valuation model for this reporting unit assumed the award of a significant project prior to the end of the second fiscal quarter, with project work to commence shortly thereafter. This project award was subsequently obtained during the first fiscal quarter of 2018, which resolved the previous contingency. In addition, operating results for the Company during the three months ended September 30, 2017, including updated forecasts for the remainder of the year, do not indicate the existence of any goodwill impairment. The Company will continue to monitor its operating results and forecasts for indicators of impairment and perform additional tests as needed. Other Intangible Assets Information on the carrying value of other intangible assets is as follows:
