GOODWILL AND INTANGIBLE ASSETS
GOODWILL AND INTANGIBLE ASSETS
Intangible assets other than goodwill and indefinite lived intangible assets are amortized over their estimated useful lives, which range between two and eighteen years, on either a straight-line basis or proportionately to the benefit being realized. We periodically review the estimated useful lives of our intangible assets and review such assets for impairment, based on estimated future cash flows, whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable. If an intangible asset is considered to be impaired, the amount of the impairment will equal the excess of the carrying value over the fair value of the asset.
We consider our business to be a single operating segment entity, and a single reporting unit engaged in the development, manufacture and sale on a global basis of medical devices for vascular access, peripheral vascular disease, oncology and surgery.
Goodwill and other intangible assets that have indefinite useful lives are not amortized, but rather, are tested for impairment annually or more frequently if impairment indicators arise. Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in each business combination. Goodwill and intangible assets have been recorded at either incurred or allocated costs based on respective fair market values at the date of acquisition.
For goodwill, the impairment test requires a comparison of the estimated fair value of the reporting unit to which the goodwill is assigned to the sum of the carrying value of the assets and liabilities of that unit. If the sum of the carrying value of the assets and liabilities of a reporting unit exceeds the fair value of the reporting unit, the carrying value of the reporting unit’s goodwill is reduced to its implied fair value through an adjustment to the goodwill balance, resulting in an impairment charge.
To determine fair value of our single reporting unit we utilized a market-based approach and an income approach. We determined the discounted cash flow as the best indicator to determine fair value and therefore assigned a weight of 75% with the remaining 25% assigned to the market approach.
Under the market-based approach, we utilized information of our Company as well as publicly available information of certain peer companies within our industry to determine earnings multiples (EBITDA).
Under the income approach, we determined fair value based on estimated future cash flows of the reporting unit, discounted by our estimated weighted-average cost of capital, which reflects the overall level of inherent risk of a reporting unit and the rate of return an outside investor would expect to earn. We used a discount rate of 12.5% to calculate the fair value of our reporting unit.
Use of the income approach in determining the fair value of a reporting unit requires the use of significant estimates and assumptions, including revenue growth rates, operating margins, discount rates and future market conditions, among others. These assumptions are highly sensitive and changes in these estimates could result in impairment. We applied gross margin assumptions, showing improvement over historical trends, improvements over historical trends of revenue of certain product lines and used a capitalization rate of 8.5% to calculate the terminal value of our reporting unit.
We completed our annual goodwill impairment test of our single reporting unit as of December 31, 2015. Our assessment of goodwill impairment indicated that the fair value of our reporting unit exceeded its carrying value and therefore goodwill was not impaired. The fair value of our reporting unit exceeded its carrying value by 9.2%.
At times our stock market capitalization has been lower than our shareholders’ equity or book value. However, our reporting unit has continued to generate significant cash flows from operations, and we expect to continue to do so in fiscal 2016 and beyond. Furthermore, we believe that a reasonable potential buyer would offer a control premium for our business that would adequately cover the difference between our stock market capitalization and our book value. The implied control premium in our annual goodwill impairment test as of December 31, 2015 is comparable to premiums identified in recent acquisitions of companies of similar size and in similar industries.
Even though we determined that there was no goodwill impairment as of December 31, 2015, the future occurrence of a potential indicator of impairment, such as a significant adverse change in legal, regulatory, business or economic conditions or a more-likely-than-not expectation that the reporting unit or a significant portion of the reporting unit will be sold or disposed of, would require an interim assessment for the reporting unit prior to the next required annual assessment as of December 31, 2016. We continued to assess impairment through May 31, 2016 and noted no events that would be considered a triggering event.
It is not possible at this time to determine if any such future impairment charge would result or, if it does, whether such charge would be material. Events that could, in the future, result in impairment include, but are not limited to, declining sales for a significant product or in a significant geographic region.

During fiscal 2015, goodwill and deferred tax liabilities were adjusted by $0.8 million due to the receipt of a New York State tax grant that was not correctly accounted for as part of purchase accounting in fiscal 2012.  The Company has determined that this adjustment was not material to any current or prior annual or interim periods.
