The risks associated with certain of our accrued insurance claims and expenses have been reinsured, and the related IBNR receivables are recognized as noncurrent assets to the extent the related liability is classified as a noncurrent liability. See Note 7. Our reserve for uncertain tax positions is discussed in Note 12. Other asset retirement obligations include amounts related to the closure and post-closure obligations associated with our Waste Management Segment’s facility in West Texas. Our Compact and Federal LLRW disposal facilities were fully certified for operations in 2012, at which time we increased our estimated asset retirement obligation by approximately $19.1 million. We recognized accretion expense of $.7 million in 2012 and $1.7 million in 2013 on the closure and post-closure obligations. We are required to provide certain financial assurance to the Texas government agencies with respect to the decommissioning obligations related to such facility, as more fully described in Note 17. Certain of our affiliates have provided or assisted us in providing such financial assurance, as discussed in Note 16. Estimates of the ultimate cost to be incurred to settle our closure and post closure obligation require a number of assumptions, are inherently difficult to develop and the ultimate outcome may differ materially from current estimates. However, we believe our experience in the environmental services business provides a reasonable basis for estimating such costs. As additional information becomes available, cost estimates will be adjusted as necessary. It is possible that technological, regulatory or enforcement developments, the results of studies or other factors could necessitate the recording of additional liabilities which could be material. The accrued litigation settlement relates to Kronos and is discussed in Note 17. The deferred payment obligation relates to Tremont and is discussed in Notes 3 and 16.
