The short-term portion balance above is included within Other current liabilities on the Condensed Consolidated Balance Sheet at June 30, 2020 and December 31, 2019.
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 $7.6 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 related solely to asset retirement obligations and was recorded based on the interest method.
