Asset Retirement Obligation Disclosure [Abstract]

ASSET RETIREMENT OBLIGATIONS

The components of the changes in the asset retirement obligation liabilities were:



(Dollars in thousands)	Short-Term Portion			Long-Term Portion			Total
Balance at January 1, 2017	$	85		$	7,472		$	7,557
Accretion	4			276			280
Amounts paid	(129		)	—			(129		)
Asset additions recorded, net	—			26			26
Reclassifications	226			(226		)	—
Balance at June 30, 2017	$	186		$	7,548		$	7,734

The balances above were included within other current liabilities and other non-current liabilities, respectively, at June 30, 2017.

Increases and reductions other than accretion, reclassification and amounts paid primarily relate to changes in estimate of the underlying liability, specifically as it relates to updates in estimated costs to remove a transmitter and the estimated timing of removal. The cost associated with the estimated removal costs and timing refinements due to ongoing network rationalization activities is expected to accrete to a total liability of $9.0 million. The total estimated liability is based on the transmitter locations remaining after we have consolidated the number of networks we operate and assume the underlying leases continue to be renewed to that future date.

Accretion expense was $0.3 million for the six months ended June 30, 2017 and 2016. Accretion expense related solely to asset retirement obligations and was recorded based on the interest method.
