asset retirement obligations an asset retirement obligation represents a legal obligation associated with the retirement of a tangible long-lived asset that is incurred upon the acquisition , construction , development or normal operation of that long-lived asset .
we recognize asset retirement obligations in the period in which they are incurred , if a reasonable estimate of fair value can be made .
the asset retirement obligation is subsequently adjusted for changes in fair value .
the associated estimated asset retirement costs are capitalized as part of the carrying amount of the long-lived asset and depreciated over its useful life .

our only conditional asset retirement obligation relates to the possible future abatement of asbestos contained in certain ppg production facilities .
the asbestos in our production facilities arises from the application of normal and customary building practices in the past when the facilities were constructed .
this asbestos is encapsulated in place and , as a result , there is no current legal requirement to abate it .
inasmuch as there is no requirement to abate , we do not have any current plans or an intention to abate and therefore the timing , method and cost of future abatement , if any , are not 40 2006 ppg annual report and form 10-k 4282_txt .
