Increases and reductions other than accretion, reclassification and amounts paid primarily relate to changes in estimates 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 $7.6 million.
Additional information regarding asset retirement costs and accretion expense can be found in Note 5, "Consolidated Financial Statements' Components."
