EXXONMOBIL SAVINGS PLAN

NOTES TO FINANCIAL STATEMENTS

Note 1:  Description of the Plan

General

Active participants in the ExxonMobil Savings Plan ("Plan") are eligible employees of Exxon Mobil Corporation ("ExxonMobil" or the “Company") and certain affiliated employers.  The terms and conditions of the Plan are contained in the ExxonMobil Benefit Plans Common Provisions document, the ExxonMobil Savings Plan document, and the ExxonMobil Savings Trust document (collectively, the "Plan Document").  The Plan is an "employee pension benefit plan" described in Section 3(2) of the Employee Retirement Income Security Act of 1974 ("ERISA") and also a "defined contribution plan" described in Section 3(34) of ERISA.  In addition, effective February 8, 2002, the entire Plan was designated an Employee Stock Ownership Plan ("ESOP").

Contributions

The Plan permits participant contributions that range from 6% to 20% of each participant’s eligible pay.  The Company matches only the minimum 6% contribution in an amount equal to 7% of a participant’s eligible pay.

Employees who are at least age 50 during the plan year and who maximize their regular pretax contributions may elect to make additional pretax contributions.  

Vesting

Participants are immediately vested in their contributions and all earnings.  Company contributions vest at 100% upon the earliest of completion of 3 years of vesting service, reaching age 65 while employed, or upon death while an employee.

Forfeitures

During 2010, employer contributions totaling $0.7 million were forfeited by terminating employees and used to offset future employer contributions.

Other Plan Provisions

Other Plan provisions including eligibility, enrollment, participation, forfeiture, loans, benefit payments (including withdrawals and distributions), and investment options are described in the Plan Document.

Plan Termination

The Company may terminate or amend the Plan at any time.  In the event of termination, the net assets of the Plan will be distributed in accordance with ERISA.

EXXONMOBIL SAVINGS PLAN

NOTES TO FINANCIAL STATEMENTS

Note 2:  Summary of Significant Accounting Policies

Basis of Accounting

The financial statements of the Plan are presented on the accrual basis.  Benefit payments are reported when paid.

Authoritative guidance clarifying the classification and measurement of participant loans by defined contribution pension plans requires participant loans to be classified as notes receivable from participants rather than as investments, as previously required.  Participant loans are measured at their unpaid principal balance plus any accrued but unpaid interest.  Such loans have been reclassified accordingly for the periods presented.  Net assets available for benefits were not affected.

Investment Valuation and Income Recognition

Investments are stated at fair value as described in Note 7.

Under the terms of its trust agreement, the Plan engaged in an authorized form of security lending activities during the years ended December 31, 2010 and 2009.  In accordance with the Securities Lending Agreement, the market value of the collateral held is required to be 100% of the market value of government securities lent and 102% for all other securities lent.  The fair value of ExxonMobil Common Assets fund securities on loan was $215 million and $225 million, at December 31, 2010 and 2009, respectively.  The securities on loan are reflected in the Statement of Net Assets Available for Benefits and the Schedule of Assets (Held at End of Year) at December 31, 2010 and 2009.  The value of cash collateral obtained and reinvested in short term investments is reflected as a liability on the Plan’s financial statements.

Purchases and sales of securities are recorded on a trade-date basis.  Dividends are recorded on the ex-dividend date.

Net appreciation and depreciation in the current value of investments includes realized gains and losses on investments sold or disposed of during the year and unrealized gains and losses on investments held at year end.

The Plan is subject to normal risks associated with international and domestic debt and equity markets, including the investment in ExxonMobil common stock.

Transfers-in include participant-initiated rollovers of certain distributions from other tax-qualified plans into the Plan.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets available for benefits and liabilities and disclosure of contingent liabilities at the date of the financial statements and the reported amounts of changes in net assets available for benefits during the reporting period.  Actual results could differ from those estimates.

NOTES TO FINANCIAL STATEMENTS

Note 3:  Party-in-Interest Transactions

During 2010, certain Plan investments were units of various funds managed by The Northern Trust Company.  The Northern Trust Company also provided custodial services to the Plan during the plan year and, therefore, purchases and sales of these investments qualified as party-in-interest transactions.

Note 4:  Tax Status

The Internal Revenue Service has determined and informed the Plan administrators by a letter dated May 19, 2011, that the Plan is qualified and the trust established under the Plan is tax-exempt under the appropriate sections of the Internal Revenue Code, provided that pre-approved amendments are adopted timely.  The Plan has been amended since requesting the determination letter.  However, counsel for the Company believes that these amendments have not adversely affected the Plan's qualified status and the related trust's tax-exempt status as of the financial statement date.

Note 5:  Expenses

Investment income from all sources is stated net of administrative expenses, which include brokerage fees on purchases and sales of ExxonMobil common stock and management fees.  Plan administration expenses, to the extent not paid by the Company, are charged to and paid from the Plan's assets.  Administrative expenses are recorded when incurred.

Note 6:  Investments

The following presents investments that represent 5 percent or more of the Plan's net assets available for benefits.

NOTES TO FINANCIAL STATEMENTS

Note 6:  Investments (continued)

During 2010, the Plan's investments (including gains and losses on investments bought and sold, as well as held during the year) appreciated in value by $1,393 million as follows:

		(millions of dollars)

	ExxonMobil common stock	$  849
	Common collective trusts	556
	Government securities	(12	)
	Corporate debt securities	(1	)
	Other	1
		$1,393

Note 7:  Assets Measured at Fair Value on a Recurring Basis

The authoritative guidance for fair value measurements provides a framework for measuring fair value. The framework establishes a three-level fair value hierarchy based on the nature of the information used to measure fair value.  The terms “Level 1” and “Level 2” are accounting terms that refer to different methods of valuing assets.  The terms do not represent the relative risk or credit quality of an investment.  The fair value hierarchies for the Plan assets are not a measure of the ability of the Plan to meet plan benefit obligations.

The following tables set forth by level, within the fair value hierarchy, the Plan's assets at fair value:

Report of Independent Registered Public Accounting Firm

To the Participants and Administrators of the ExxonMobil Savings Plan:

In our opinion, the accompanying statements of net assets available for benefits and the related statement of changes in net assets available for benefits present fairly, in all material respects, the net assets available for benefits of the ExxonMobil Savings Plan (the “Plan”) at December 31, 2010 and 2009 and the changes in net assets available for benefits for the year ended December 31, 2010 in conformity with accounting principles generally accepted in the United States of America.  These financial statements are the responsibility of the Plan’s management.  Our responsibility is to express an opinion on these financial statements based on our audits.  We conducted our audits of these statements in accordance with the standards of the Public Company Accounting Oversight Board (United States).  Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement.  An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation.  We believe that our audits provide a reasonable basis for our opinion.

Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole.  The supplemental Schedule of Assets (Held At End of Year) is presented for the purpose of additional analysis and is not a required part of the basic financial statements but is supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974.  This supplemental schedule is the responsibility of the Plan's management.  The supplemental schedule has been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole.
