In 2008, before-tax income for U.S. operations, including related corporate and other charges, was $10,682, compared with before-tax income of $7,794 and $9,131 in 2007 and 2006, respectively. For international operations, before-tax income was $32,275, $24,373 and $22,845 in 2008, 2007 and 2006, respectively. U.S. federal income tax expense was reduced by $198, $132 and $116 in 2008, 2007 and 2006, respectively, for business tax credits.

The reconciliation between the U.S. statutory federal income tax rate and the company's effective income tax rate is explained in the table below:

  Year ended December 31
2008 2007 2006
U.S. statutory federal income tax rate 35.0% 35.0% 35.0%
Effect of income taxes from international operations at rates different from the U.S. statutory rate 10.2 8.3 10.3
State and local taxes on income, net of U.S. federal income tax benefit 1.0 0.8 1.0
Prior-year tax adjustments (0.1) 0.3 0.9
Tax credits (0.5) (0.4) (0.4)
Effects of enacted changes in tax laws (0.6) (0.3) 0.3
Other (0.7) (1.8) (0.7)
Effective tax rate 44.3% 41.9% 46.4%

The company's effective tax rate increased from 41.9 percent in 2007 to 44.3 percent in 2008. The increase in the "Effect of income taxes from international operations at rates different from the U.S. statutory rate" from 8.3 percent in 2007 to 10.2 percent in 2008 was mainly due to a greater proportion of income being earned in 2008 in tax jurisdictions with higher tax rates. In addition, the 2007 period included a relatively low tax rate on the sale of downstream assets in Europe. The change in "Other" from a negative 1.8 percent to a negative 0.7 percent primarily related to a lower effective tax rate on the sale of the company's investment in Dynegy common stock in 2007.

The company records its deferred taxes on a tax- jurisdiction basis and classifies those net amounts as current or noncurrent based on the balance sheet classification of the related assets or liabilities. The reported deferred tax balances are composed of the following:

At December 31
2008 2007
Deferred tax liabilities    
Properties, plant and equipment $18,271 $17,310
Investments and other 2,225 1,837
Total deferred tax liabilities 20,496 19,147
Deferred tax assets    
Abandonment/environmental reserves (4,338) (3,587)
Employee benefits (3,488) (2,148)
Tax loss carryforwards (1,139) (1,603)
Deferred credits (3,933) (1,689)
Foreign tax credits (4,784) (3,138)
Inventory (260) (608)
Other accrued liabilities (445) (477)
Miscellaneous (1,732) (1,528)
Total deferred tax assets (20,119) (14,778)
Deferred tax assets valuation allowance 7,535 5,949
Total deferred taxes, net $7,912 $10,318

Deferred tax liabilities at the end of 2008 increased by approximately $1,300 from year-end 2007. The increase was primarily related to increased temporary differences for properties, plant and equipment.

Deferred tax assets increased by approximately $5,300 in 2008. The increase related primarily to deferred credits recorded for future tax benefits earned from a new field in Africa ($2,200); increased deferred tax benefits for pension related obligations ($1,300); and additional foreign tax credits arising from earnings in high-tax-rate international jurisdictions ($1,600), which were substantially offset by valuation allowances.

The overall valuation allowance relates to foreign tax credit carryforwards, tax loss carryforwards and temporary differences for which no benefit is expected to be realized. Tax loss carryforwards exist in many international jurisdictions. Whereas some of these tax loss carryforwards do not have an expiration date, others expire at various times from 2009 through 2032. Foreign tax credit carryforwards of $4,784 will expire between 2009 and 2018.

At December 31, 2008 and 2007, deferred taxes were classified in the Consolidated Balance Sheet as follows:

  At December 31
2008 2007
Prepaid expenses and other current assets $(1,130) $(1,234)
Deferred charges and other assets (2,686) (812)
Federal and other taxes on income 189 194
Noncurrent deferred income taxes 11,539 12,170
Total deferred income taxes, net $7,912 $10,318

Income taxes are not accrued for unremitted earnings of international operations that have been or are intended to be reinvested indefinitely. Undistributed earnings of international consolidated subsidiaries and affiliates for which no deferred income tax provision has been made for possible future remittances totaled $22,428 at December 31, 2008. This amount represents earnings reinvested as part of the company's ongoing international business. It is not practicable to estimate the amount of taxes that might be payable on the eventual remittance of earnings that are intended to be reinvested indefinitely. At the end of 2008, deferred income taxes were recorded for the undistributed earnings of certain international operations for which the company no longer intends to indefinitely reinvest the earnings. The company does not anticipate incurring significant additional taxes on remittances of earnings that are not indefinitely reinvested.

Uncertain Income Tax Positions

Financial Accounting Standards Board (FASB) Interpretation No. 48, Accounting for Uncertainty in Income Taxes — An Interpretation of FASB Statement No. 109 (FIN 48), provides the accounting guidance for income tax benefits that are uncertain in nature. Under FIN 48, a company recognizes a tax benefit in the financial statements for an uncertain tax position only if management's assessment is that the position is "more likely than not" (i.e., a likelihood greater than 50 percent) to be allowed by the tax jurisdiction based solely on the technical merits of the position. The term "tax position" in FIN 48 refers to a position in a previously filed tax return or a position expected to be taken in a future tax return that is reflected in measuring current or deferred income tax assets and liabilities for interim or annual periods.

The following table indicates the changes to the company's unrecognized tax benefits for the year ended December 31, 2008. The term "unrecognized tax benefits" in FIN 48 refers to the differences between a tax position taken or expected to be taken in a tax return and the benefit measured and recognized in the financial statements in accordance with the guidelines of FIN 48. Interest and penalties are not included.

2008 2007
Balance at January 1 $2,199 $2,296
Foreign currency effects (1) 19
Additions based on tax positions taken in current year 522 418
Reductions based on tax positions taken in current year (17)
Additions/reductions resulting from current year asset acquisitions/sales 175
Additions for tax positions taken in prior years 337 120
Reductions for tax positions taken in prior years (246) (225)
Settlements with taxing authorities in current year (215) (255)
Reductions as a result of a lapse of the applicable statute of limitations (58)
Reductions due to tax positions previously expected to be taken but subsequently not taken on prior year tax returns (174)
Balance at December 31 $2,696 $2,199

Although unrecognized tax benefits for individual tax positions may increase or decrease during 2009, the company believes that no change will be individually significant during 2009. Approximately 85 percent of the $2,696 of unrecognized tax benefits at December 31, 2008, would have an impact on the effective tax rate if subsequently recognized.

Tax positions for Chevron and its subsidiaries and affiliates are subject to income tax audits by many tax jurisdictions throughout the world. For the company's major tax jurisdictions, examinations of tax returns for certain prior tax years had not been completed as of December 31, 2008. For these jurisdictions, the latest years for which income tax examinations had been finalized were as follows: United States — 2003, Nigeria — 1994, Angola — 2001 and Saudi Arabia — 2003.

On the Consolidated Statement of Income, the company reports interest and penalties related to liabilities for uncertain tax positions as "Income tax expense." As of December 31, 2008, accruals of $276 for anticipated interest and penalty obligations were included on the Consolidated Balance Sheet, compared with accruals of $198 as of year-end 2007. Income tax expense associated with interest and penalties was $79 and $70 in 2008 and 2007, respectively.
