AMERICAN TOWER CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) Asset Retirement Obligations—The Company complies with the provisions of SFAS No.143, “Accounting for Asset Retirement Obligations” (SFAS No.143) and the provisions of Financial Accounting Standards Board (FASB) Interpretation No.47 “Accounting for Conditional Asset Retirement Obligations” (FIN No.47).
Both pronouncements address the financial accounting and reporting requirements for conditional obligations associated with the Company’s legal obligation to retire tangible long-lived assets and the related asset retirement costs.
The fair value of a liability for asset retirement obligations is recognized in the period in which it is incurred and can be reasonably estimated.
Such asset retirement costs are capitalized as part of the carrying amount of the related long-lived asset and depreciated over the asset’s estimated useful life.
Fair value estimates of liabilities for asset retirement obligations generally involve discounting of estimated future cash flows.
Periodic accretion of such liabilities due to the passage of time is recorded as an operating expense.
The Company has certain legal obligations related to tower assets which fall within the scope of SFAS No.143 and FIN No.47, principally obligations to remediate leased land on which certain of the Company’s tower assets are located.
The significant assumptions used in estimating the Company’s aggregate asset retirement obligation are: timing of tower removals; cost of tower removals; timing and number of land lease renewals; expected inflation rates; and creditadjusted risk-free interest rates that approximate the Company’s incremental borrowing rate.
The adoption of FIN No.47 primarily resulted in the acceleration of settlement date assumptions, as FIN No.47 precludes the Company from considering non-contractual lease renewal periods in determining its settlement date assumptions.
The Company adopted the provisions of SFAS No.143 as of January 1, 2003 and the provisions of FIN No.47 as of December 31, 2005.
Upon adoption of the provisions of FIN No.47, the Company recognized a $35.5 million charge (net of an $11.7 million tax benefit) as a cumulative effect of a change in accounting principle in the consolidated statement of operations for the year ended December 31, 2005.
In addition, the adoption of FIN No.47 resulted in an increase to the tower assets included in property and equipment, net of $66.9 million.
Had the Company adopted the provisions of FIN No.47 as of January 1, 2004, the aggregate asset retirement obligation as of January 1, 2004 and December 31, 2004 would have approximated $92.9 million and $99.5 million, respectively.
Had the Company adopted the provisions of FIN No.47 in prior periods, net loss for the year ended December 31, 2004 would have been approximately $(0.3) million and basic and diluted net loss per share for the year ended December 31, 2004 would have been approximately $(1.17).
The Company’s asset retirement obligation is included in other long-term liabilities in the accompanying consolidated balance sheets.
The changes in the carrying value of the Company’s asset retirement obligations for years ended December 31, 2006, 2005 and 2004 are as follows (in thousands):
## Table 0 ##
Fair Value of Financial Instruments—The carrying values of the Company’s financial instruments, with the exception of long-term obligations, including current portion, reasonably approximate the related fair values as of December 31, 2006 and 2005.

As of December 31, 2005, the carrying amount and fair value of long-term obligations, including current portion, were $3.6 billion and

RISK MANAGEMENT As a financial services company, our business is exposed to certain risks.
The identification, mitigation and management of existing and potential risks is critical to effective enterprise risk management.
There are certain risks inherent to our industry (e. g.  execution of transactions) and certain risks that will surface through the conduct of our business operations.
We seek to monitor and manage our significant risk exposures by operating under a set of Board-approved limits and by monitoring certain risk indicators.
Our governance framework requires regular reporting on metrics, significant risks and exposures to senior management and the Board of Directors.
Our risk management framework, as described below, is in compliance with all applicable requirements.
We have a Board-approved Enterprise Risk Appetite Statement (RAS) that is provided to all employees.
The RAS specifies significant risk exposures and addresses the Company's tolerance of those risks, which are categorized as follows, with further information provided below
