Total other intangible assets decreased by $5.2 million for the six months ended June 30, 2017 primarily due to amortization expense of $10.5 million for the six months ended June 30, 2017, partially offset by $3.7 million and $0.9 million of definite-lived other intangible assets related to customer intangibles from our acquisitions of Illinois video gaming terminal operators and Bally’s and Resorts, respectively, in 2017. Other intangible assets have a weighted average remaining amortization period of 5.5 years.

The Company’s intangible asset amortization expense was $5.3 million and $10.5 million, for the three and six months ended June 30, 2017, respectively, as compared to $0.5 million and $1.0 million for the three and six months ended June 30, 2016, respectively. The increase is primarily due to the intangible assets recognized with our acquisition of Rocket Speed on August 1, 2016.

The following table presents expected intangible asset amortization expense based on existing intangible assets as of June 30, 2017 (in thousands):
