Intangible Assets and Goodwill
The following tables summarize the carrying amounts and related accumulated amortization for intangible assets as of December 31, 2018 and September 30, 2018.
The net change in intangible assets during the three months ended December 31, 2018 was driven primarily by the acquisition of BM&M in November 2018, which included intangible assets of approximately $14, normal amortization, and foreign currency adjustments. See Note 4 for further detail on the acquisition of BM&M.
Goodwill is not amortized, but is subject to annual impairment tests. Goodwill has been assigned to reporting units. We assess the carrying value of goodwill annually, or more often if events or changes in circumstances indicate there may be impairment. Impairment testing is performed at a reporting unit level.
