AMERICAN TOWER CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) Basis step-up from corporate restructuring represents the tax effects of increasing the basis for tax purposes of certain of the Company’s assets in conjunction with its spin-off from American Radio Systems Corporation, its former parent company.
At December 31, 2006, the Company had net federal and state operating loss carryforwards available to reduce future taxable income of approximately $2.1 billion and $2.5 billion, respectively.
If not utilized, the Company’s net operating loss carryforwards expire as follows (in thousands):
## Table 0 ##
SFAS No.109, “Accounting for Income Taxes,” requires that companies record a valuation allowance when it is “more likely than not that some portion or all of the deferred tax assets will not be realized.
” At December 31, 2006, the Company has provided a valuation allowance of approximately $308.2 million, including approximately $153.6 million attributable to SpectraSite, primarily related to net operating loss and capital loss carryforwards assumed as of the acquisition date.
The balance of the valuation allowance primarily relates to net state deferred tax assets.
The Company has not provided a valuation allowance for the remaining deferred tax assets, primarily its federal net operating loss carryforwards, as management believes the Company will have sufficient time to realize these federal net operating loss carryforwards during the twenty-year tax carryforward period.
Valuation allowances may be reversed if related deferred tax assets are deemed realizable based on changes in facts and circumstances relevant to the assets’ recoverability.
Approximately $148.3 million of the SpectraSite valuation allowances as of December 31, 2006 will be recorded as a reduction to goodwill if the underlying deferred tax assets are utilized.
The Company intends to recover a portion of its deferred tax asset through its federal income tax refund claims related to the carry back of certain federal net operating losses.
In June 2003 and October 2003, the Company filed federal income tax refund claims with the IRS relating to the carry back of $380.0 million of net operating losses generated prior to 2003, of which the Company initially anticipated receiving approximately $90.0 million.
Based on preliminary discussions with tax authorities, the Company revised its estimate of the net realizable value of the federal income tax refund claims during the year ended December 31, 2005, and anticipates receiving a refund of approximately $65.0 million, plus interest.
The Company expects settlement of this matter in the first half of 2007, however, there can be no assurances with respect to the timing of any refund.
Because of the uncertainty associated with the claim, the Company has not recognized any amounts related to interest.
The recoverability of the Company’s remaining net deferred tax asset has been assessed utilizing stable state (no growth) projections based on its current operations.
The projections show a significant decrease in depreciation in the later years of the carryforward period as a result of a significant portion of its assets being fully depreciated during the first fifteen years of the carryforward period.
Accordingly, the recoverability of the net deferred tax asset is not dependent on material improvements to operations, material asset sales or other non-routine transactions.
Based on its current outlook of future taxable income during the carryforward period, management believes that the net deferred tax asset will be realized.
The realization of the Company’s deferred tax assets as of December 31, 2006 will be dependent upon its ability to generate approximately $1.4 billion in taxable income from January 1, 2007 to December 31, 2026.
If the Company is unable to generate sufficient taxable income in the future, or carry back losses, as described above, it
Gross other postretirement benefit payments for the next ten years, which reflect expected future service where appropriate, and gross subsidies to be received under the Prescription Drug Act are expected to be as follows:
## Table 1 ##
Insolvency Assessments Most of the jurisdictions in which the Company is admitted to transact business require insurers doing business within the jurisdiction to participate in guaranty associations, which are organized to pay contractual benefits owed pursuant to insurance policies issued by impaired, insolvent or failed insurers.
These associations levy assessments, up to prescribed limits, on all member insurers in a particular state on the basis of the proportionate share of the premiums written by member insurers in the lines of business in which the impaired, insolvent or failed insurer engaged.
Some states permit member insurers to recover assessments paid through full or partial premium tax offsets.
Assets and liabilities held for insolvency assessments are as follows:
## Table 2 ##
(1) The Company holds a receivable from the seller of a prior acquisition in accordance with the purchase agreement.
Assessments levied against the Company were ($1) million, $2 million and $4 million for the years ended December 31, 2007, 2006 and 2005, respectively.
Effects of Inflation The Company does not believe that inflation has had a material effect on its consolidated results of operations, except insofar as inflation may affect interest rates.
Adoption of New Accounting Pronouncements Income Taxes Effective January 1, 2007, the Company adopted FIN 48.
FIN 48 clarifies the accounting for uncertainty in income tax recognized in a company’s financial statements.
FIN 48 requires companies to determine whether it is “more likely than not” that a tax position will be sustained upon examination by the appropriate taxing authorities before any part of the benefit can be recorded in the financial statements.
It also provides guidance on the recognition, measurement, and classification of income tax uncertainties, along with any related interest and penalties.
Previously recorded income tax benefits that no longer meet this standard are required to be charged to earnings in the period that such determination is made.
As a result of the implementation of FIN 48, the Company recognized a $52 million increase in the liability for unrecognized tax benefits, a $4 million decrease in the interest liability for unrecognized tax benefits, and a corresponding reduction to the January 1, 2007 balance of retained earnings of $37 million, net of $11 million of minority interest.
Insurance Contracts Effective January 1, 2007, the Company adopted SOP 05-1, Accounting by Insurance Enterprises for Deferred Acquisition Costs in Connection with Modifications or Exchanges of Insurance Contracts.
SOP 05-1 which provides guidance on accounting by insurance enterprises for DAC on internal replacements of insurance and investment contracts other than those specifically described in SFAS No.97, Accounting and Reporting by Insurance Enterprises for Certain Long-Duration Contracts and for Realized Gains and Losses from the Sale of Investments.
SOP 05-1 defines an internal replacement and is effective for internal replacements occurring in fiscal years beginning after December 15, 2006.
In addition, in February 2007, the American Institute of Certified Public Accountants (“AICPA”) issued related Technical Practice Aids (“TPAs”) to provide further clarification of SOP 05-1.
The TPAs became effective concurrently with the adoption of SOP 05-1.
As a result of the adoption of SOP 05-1 and the related TPAs, if an internal replacement modification substantially changes a contract, then the DAC is written off immediately through income and any new deferrable costs associated with the new replacement are deferred.
If a contract modification does not substantially change the contract, the DAC amortization on the original contract will continue and any acquisition costs associated with the related modification are immediately expensed.
The adoption of SOP 05-1 and the related TPAs resulted in a reduction to DAC and VOBA on January 1, 2007 and an acceleration of the amortization period relating primarily to the Company’s group life and health insurance contracts that contain certain rate reset provisions.
Prior to the adoption of SOP 05-1, DAC on such contracts was amortized over the expected renewable life of the contract.
Upon adoption
