AMERICAN TOWER CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) For the years ended December 31, 2007 and 2006, the Company increased net deferred tax assets by $1.5 million and $7.2 million, respectively with a corresponding reduction of goodwill associated with the utilization of net operating and capital losses acquired in connection with the SpectraSite, Inc.  merger.
These deferred tax assets were assigned a full valuation allowance as part of the final SpectraSite purchase price allocation in June 2006, as evidence available at the time did not support that losses were more likely than not to be realized.
The valuation allowance decreased from $308.2 million as of December 31, 2006 to $88.2 million as of December 31, 2007.
The decrease was primarily due to a $149.6 million reclassification to the FIN 48 opening balance (related to federal and state net operating losses acquired in connection with the SpectraSite, Inc.  merger) and $45.2 million of allowance reductions during the year ended December 31, 2007 related to state net operating losses, capital loss expirations of $6.5 million and other items.
The Company’s deferred tax assets as of December 31, 2007 and 2006 in the table above do not include $74.9 million and $31.0 million, respectively, of excess tax benefits from the exercises of employee stock options that are a component of net operating losses due to the adoption of SFAS No.123R.
Total stockholders’ equity will be increased by $74.9 million if and when any such excess tax benefits are ultimately realized.
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, 2007, the Company had net federal and state operating loss carryforwards available to reduce future federal and state taxable income of approximately $1.6 billion and $2.1 billion, respectively.
If not utilized, the Company’s net operating loss carryforwards expire as follows (in thousands):
## Table 0 ##
As described in note 1, the Company adopted the provisions of FIN 48 on January 1, 2007.
As of January 1, 2007, the total amount of unrecognized tax benefits was $183.9 million of which $34.3 million would affect the effective tax rate, if recognized.
As of December 31, 2007, the total amount of unrecognized tax benefits was $59.2 million, $23.0 million of which would affect the effective tax rate, if recognized.
The Company expects the unrecognized tax benefits to change over the next 12 months if certain tax matters ultimately settle with the applicable taxing jurisdiction during this timeframe.
However, based on the status of these items and the amount of uncertainty associated with the outcome and timing of audit settlements, the

## Table 2 ##
Retirement Benefit Plan Asset Fair Values The following is a description of the valuation methodologies used for retirement benefit plan assets measured at fair value: Short-term investments: Valued at the closing price reported in the active markets in which the individual security is traded.
U. S.  government securities: Certain U. S.  government securities are valued at the closing price reported in the active markets in which the individual security is traded.
Other U. S.  government securities are valued based on inputs other than quoted prices that are observable.
Corporate debt securities: Valued based on inputs other than quoted prices that are observable.
Equity commingled trusts: Comprised of investments in equity securities held in pooled investment vehicles.
The valuations of equity commingled trusts are based on the respective net asset values which are determined by the fund daily at market close.
The net asset values are calculated based on the valuation of the underlying assets which are determined using observable inputs.
The net asset values are not publicly reported and funds are valued at the net asset value practical expedient.
Fixed income commingled trusts: Comprised of investments in fixed income securities held in pooled investment vehicles.
The valuations of fixed income commingled trusts are based on the respective net asset values which are determined by the fund daily at market close.
The net asset values are calculated based on the valuation of the underlying assets which are determined using observable inputs.
The net asset values are not publicly reported and funds are valued at the net asset value practical expedient.
Partnership units: Valued based on the year-end net asset values of the underlying partnerships.
The net asset values of the partnerships are based on the fair values of the underlying investments of the partnerships.
Quoted market prices are used to value the underlying investments of the partnerships, where the partnerships consist of the investment pools which invest primarily in common stocks.
Partnership units include partnerships, private equity investments, and real asset investments.
Partnerships primarily include long/short equity and absolute return strategies.
These investments may be redeemed monthly with notice periods ranging from 45 to 95 days.
At April 27, 2018, there are no funds in the process of liquidation.
Private equity investments consist of common stock and debt instruments of private companies.
For private equity funds, the sum of the unfunded commitments at April 27, 2018 is $168 million, and the estimated liquidation period of these funds is expected to be one to 15 years.
Real asset investments consist of commodities, derivatives, Real Estate Investment Trusts, and illiquid real estate holdings.
These investments have redemption and liquidation periods ranging from 30 days to 10 years.
At April 27, 2018, there are no real estate investments in the process of liquidation.
The Company expects to receive the proceeds over the next year.
Other valuation procedures are utilized to arrive at fair value if a quoted market price is not available for a partnership investment.
Registered investment companies: Valued at net asset values which are not publicly reported.
The net asset values are calculated based on the valuation of the underlying assets.
The underlying assets are valued at the quoted market prices of shares held by the plan at year-end in the active market on which the individual securities are traded.
Insurance contracts: Comprised of investments in collective (group) insurance contracts, consisting of individual insurance policies.
The policyholder is the employer and each member is the owner/ beneficiary of their individual insurance policy.
These policies are a part of the insurance company’s general portfolio and participate in the insurer’s profit-sharing policy on an excess yield basis.
The methods described above may produce fair values that may not be indicative of net realizable value or reflective of future fair values.
Furthermore, while the Company believes its valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine fair value of certain financial instruments could result in a different fair value measurement at the reporting date.
There were no transfers between Level 1, Level 2, or Level 3 during fiscal years 2018 or 2017.
These increases were partially offset by: ?
a $46 million net decrease in revenues due to unfavorable foreign currency effects, comprised of unfavorable effects of $36 million and $10 million related to our comparable and non-comparable store sales, respectively, primarily related to the weakening of the Euro and the Yen against the U. S.  Dollar during Fiscal 2013.
Our global average store count declined by three stores and concession shops during Fiscal 2013, as store closures associated with the Asia-Pacific Restructuring Plan at the end of Fiscal 2012 and the Rugby Closure Plan in Fiscal 2013 were largely offset by new store openings, primarily in Asia and Europe.
