Other Intangible Assets

The Company’s finite-lived intangible assets are stated at cost less accumulated amortization. The Company assesses its intangible and other long-lived assets for impairment whenever events or changes in circumstances suggest that the carrying value of an asset may not be recoverable. The Company recognizes an impairment loss for intangibles and other finite-lived assets if the carrying amount of a long-lived asset is not recoverable based on its undiscounted future cash flows. Any such impairment loss is measured as the difference between the carrying amount and the fair value of the asset. The estimation of useful lives and expected cash flows requires the Company to make significant judgments regarding future periods that are subject to some factors outside its control. Changes in these estimates can result in significant revisions to the carrying value of these assets and may result in material charges to the results of operations. The Company recorded $32.9 million of other intangible assets as a result of the acquisition of Neighborhood Diabetes. The estimated life of the acquired tradename asset is 15 years. The estimated useful life of the acquired customer relationship asset is 10 years. Intangible assets with determinable estimated lives are amortized over these lives.

The Company recorded $2.1 million of other intangible assets in the nine months ended September 30, 2015 as a result of the acquisition of its Canadian distribution business (see Footnote 3 for further description). The Company determined that the estimated useful life of the contractual relationship asset is 5 years and is amortizing the asset over the estimated lives, based on the expected cash flows of the assets, accordingly. The amortization of other intangible assets was approximately $0.5 million for the three and nine months ended September 30, 2015. Amortization expense for the year ending December 31, 2015 is expected to be approximately $1.0 million.

Other intangible assets consist of the following (in thousands):
