3. Common Stock Repurchase Program

On August 28, 2008, the Company’s Board of Directors authorized the repurchase of up to two million shares of the Company’s Common Stock. Shares are effectively retired at the time of purchase. During the six months ended June 30, 2011, the Company did not repurchase any shares under this plan. As of June 30, 2011, the Company has repurchased and retired 1,762,576 shares at an aggregate price of $65,925.

4. Dividends Paid

On March 22, 2011, the Board of Directors declared a cash dividend of $0.20 per common share payable to shareholders of record on May 2, 2011. The dividend was paid on May 16, 2011. On July 19, 2011, the Board of Directors declared a cash dividend of $0.24 per common share payable to shareholders of record on August 1, 2011. This dividend is payable on August 15, 2011.

5. Comprehensive Income

The following table sets forth the components of comprehensive income:

	Three months ended June 30,					Six months ended June 30,
		2011		2010			2011		2010
Net income	$	29,944	$	18,734		$	60,108	$	37,726
Foreign currency translation adjustment		845		(3,051	)		4,441		(1,763	)
Comprehensive income	$	30,789	$	15,683		$	64,549	$	35,963

The foreign currency translation adjustment for the three months ended June 30, 2011 and 2010 is net of deferred income tax expense of $591 and none, respectively. For the six months ended June 30, 2011 and 2010, the foreign currency translation adjustment is net of deferred income tax expense of $810 and none, respectively.

6. Stock Based Compensation

The CARBO Ceramics Inc. Omnibus Incentive Plan (the “Omnibus Incentive Plan”), which replaced the previously expired restricted stock and stock option plans, provides for granting of cash-based awards, stock options (both non-qualified and incentive) and other equity-based awards (including stock appreciation rights, phantom stock, restricted stock, restricted stock units, performance shares, deferred share units or share-denominated performance units) to employees and non-employee directors. The amount paid under the Omnibus Incentive Plan to any single participant in any calendar year with respect to any cash-based award shall not exceed $2,000. Awards may be granted with respect to a number of shares of the Company’s Common Stock that in the aggregate does not exceed 750,000 shares prior to the fifth anniversary of its effective date, plus (i) the number of shares that are forfeited, cancelled or returned, and (ii) the number of shares that are withheld from the participants to satisfy an option exercise price or minimum statutory tax withholding obligations. No more than 50,000 shares may be granted to any single participant in any calendar year. Equity-based awards may be subject to performance-based and/or service-based conditions. With respect to stock options and stock appreciation rights granted, the exercise price shall not be less than the market value of the underlying Common Stock on the date of grant. The maximum term of an option is ten years. Restricted stock awards granted generally vest (i.e., transfer and forfeiture restrictions on these shares are lifted) proportionately on each of the first three anniversaries of the grant date, but subject to certain limitations, awards may specify other vesting periods. As of June 30, 2011, 615,186 shares were available for issuance under the Omnibus Incentive Plan. Although the Company’s previous restricted stock and stock option plans have expired, outstanding options and unvested shares granted under these plans remain outstanding in accordance with their terms.

The Company also had a Director Deferred Fee Plan (the “Plan”), which terminated on January 19, 2010, that permitted non-employee directors of the Company to defer receipt of cash compensation for service as a director and to receive those fees in the form of the Company’s Common Stock on a specified later date that was on or after the director’s retirement from the Board of Directors. In January 2011, a total of 4,058 shares were issued in full payment of $171 of deferred fees remaining under the Plan to electing directors.

A summary of stock option activity and related information for the six months ended June 30, 2011 is presented below:

	Options	Weighted- Average Exercise Price	Aggregate Intrinsic Value
Outstanding at January 1, 2011	5,900	$22.04
Granted	—	—
Exercised	(3,475)	$21.83
Forfeited	—	—
Outstanding at June 30, 2011	2,425	$22.35	$341
Exercisable at June 30, 2011	2,425	$22.35	$341

As of June 30, 2011, all compensation cost related to stock options granted under the expired stock option plans has been recognized. The weighted-average remaining contractual term of options outstanding at June 30, 2011 was 1.3 years. The total intrinsic value of options exercised during the six months ended June 30, 2011 was $346.

A summary of restricted stock activity and related information for the six months ended June 30, 2011 is presented below:

	Shares	Weighted- Average Grant- Date Fair Value
Nonvested at January 1, 2011	134,276	$  51.20
Granted	54,740	$104.07
Vested	(53,321)	$  47.01
Forfeited	(2,006)	$  75.91
Nonvested at June 30, 2011	133,689	$  74.15

As of June 30, 2011, there was $6,684 of total unrecognized compensation cost, net of estimated forfeitures, related to restricted shares granted under the restricted stock plans. That cost is expected to be recognized over a weighted-average period of 1.7 years. The total fair value of shares vested during the six months ended June 30, 2011 was $2,507.

The Company also had an International Long-Term Incentive Plan that provided for granting units of stock appreciation rights (“SARs”) or phantom shares to key international employees. This plan was replaced by the Omnibus Incentive Plan. One-third of the units subject to an award vests and ceases to be forfeitable on each of the first three anniversaries of the grant date. Participants awarded units of SARs have the right to receive an amount, in cash, equal to the excess of the fair market value of a share of Common Stock as of the vesting date, or in some cases on a later exercise date chosen by the participant, over the exercise price. Participants awarded units of phantom shares are entitled to a lump sum cash payment equal to the fair market value of a share of Common Stock on the vesting date. In no event will Common Stock of the Company be issued under either plan with regard to outstanding SARs or phantom shares. As of June 30, 2011, there were 21,565 units of phantom shares granted under the plans, of which 12,153 have vested and 790 have been forfeited, with a total value of $1,405, the vested portion of which is recorded as a liability within Other Accrued Expenses.

7. Bank Borrowings

The Company has an unsecured revolving credit agreement with a bank. Under the terms of the agreement, dated January 29, 2010, the Company can borrow up to $10,000. The Company has the option of choosing either the bank’s fluctuating Base Rate or LIBOR Fixed Rate, plus an Applicable Margin, all as defined in the credit agreement. The terms of the credit agreement provide for certain affirmative and negative covenants and require the Company to maintain certain financial ratios. Commitment fees are payable quarterly at the annual rate of 0.50% of the unused line of credit.

8

8. Foreign Currencies

As of June 30, 2011, the Company’s net investment that is subject to foreign currency fluctuations totaled $88,497 and the Company has recorded cumulative foreign currency translation income of $327, net of deferred income tax expense. This cumulative translation income is included in Accumulated Other Comprehensive Income (Loss).

9. New Accounting Pronouncements

In December 2010, the Financial Accounting Standards Board (“FASB”) issued authoritative guidance on application of goodwill impairment model when a reporting unit has a zero or negative carrying amount. When a reporting unit has a zero or negative carrying value, Step 2 of the goodwill impairment test should be performed if qualitative factors indicate that it is more likely than not that a goodwill impairment exists. The guidance is effective for the Company beginning in the first quarter of fiscal 2012. The Company is currently evaluating the potential impact, if any, of the adoption of this guidance on its consolidated financial statements.

In December 2010, the FASB issued authoritative guidance on disclosure of supplementary pro forma information for business combinations. The new guidance requires that pro forma financial information should be prepared as if the business combination occurred as of the beginning of the prior annual period. The guidance is effective for the Company for business combinations with acquisition dates occurring in and from the first quarter of fiscal 2012.

In June 2011, the FASB issued ASU No. 2011-05, “Comprehensive Income (ASC Topic 220): Presentation of Comprehensive Income,” (“ASU 2011-05”) which amends current comprehensive income guidance. This accounting update eliminates the option to present the components of other comprehensive income as part of the statement of shareholders’ equity. Instead, the Company must report comprehensive income in either a single continuous statement of comprehensive income which contains two sections, net income and other comprehensive income, or in two separate but consecutive statements. ASU 2011-05 will be effective for public companies during the interim and annual periods beginning after Dec. 15, 2011 with early adoption permitted. The adoption of ASU 2011-05 will not have an impact on the Company’s consolidated financial position, results of operations or cash flows as it only requires a change in the format of the current presentation.

10. Legal Proceedings

The Company is subject to legal proceedings, claims and litigation arising in the ordinary course of business. While the outcome of these matters is currently not determinable, management does not expect that the ultimate costs to resolve these matters will have a material adverse effect on the Company’s consolidated financial position, results of operations, or cash flows.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Business

The Company generates revenue primarily through the sale of products and services to the oil and natural gas industry. The Company’s principal business consists of manufacturing and selling ceramic proppant for use primarily in the hydraulic fracturing of oil and natural gas wells. The Company recently commenced the sale of resin-coated sand, which is an alternative to both ceramic proppant and raw frac sand, in order to broaden its proppant suite of products. The Company also provides the industry’s most popular fracture simulation software FracPro^®, as well as fracture design and consulting services. In addition, the Company provides a broad range of technologies for spill prevention, containment and countermeasures, along with geotechnical monitoring.

Critical Accounting Policies

The consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States, which require the Company to make estimates and assumptions (see Note 1 to the consolidated financial statements included in the annual report on Form 10-K for the year ended December 31, 2010). The Company believes that some of its accounting policies involve a higher degree of judgment and complexity than others. As of December 31, 2010, critical accounting policies for the Company included revenue recognition, estimating the recoverability of accounts receivable, inventory valuation, accounting for income taxes and accounting for long-lived assets. These critical accounting policies are discussed more fully in the Company’s annual report on Form 10-K for the year ended December 31, 2010. There have been no changes in the Company’s evaluation of its critical accounting policies since December 31, 2010.

Results of Operations

Three Months Ended June 30, 2011

Revenues. Revenues of $149.7 million for the quarter ended June 30, 2011 increased 34% compared to $111.5 million in revenues for the same period in 2010. The increase is mainly attributed to a 23% increase in proppant sales volume and an increase in the average proppant selling price as a result of price increases. Worldwide proppant sales volume totaled 387 million pounds for the second quarter of 2011 compared to 314 million pounds for the second quarter of 2010. North American (defined as Canada and the U.S.) sales volume increased 26% largely driven by an increase in the drilling rig count in the U.S. and Canada as well as continued acceptance of the Company’s products in unconventional resource plays, including shale formations. North American proppant volumes were also favorably impacted by the availability of additional product from the Company’s recently completed third manufacturing line in Toomsboro, Georgia and increases in sales of other proppants, including CARBOBond^® resin-coated sand and ceramic proppant that meets standards published by the American Petroleum Institute (“API”) and the International Organization for Standardization (“ISO”) manufactured on an outsourced basis. International (excluding Canada) sales volume increased 10% primarily due to increased sales volumes in China. The average selling price per pound of ceramic proppant was $0.356 during the second quarter of 2011 compared to $0.322 for the same period in 2010.

Gross Profit. Gross profit for the second quarter of 2011 was $62.1 million, or 42% of revenues, compared to $41.2 million, or 37% of revenues, for the second quarter of 2010. The increase in gross profit, as well as gross profit as a percentage of revenues, were primarily the result of higher proppant sales volumes, an increase in the average proppant selling price, a change in product mix and greater contribution from the Company’s other business units, partially offset by an increase in freight costs.

Selling, General and Administrative (SG&A) and Other Operating Expenses. SG&A expenses totaled $15.8 million for the second quarter of 2011 compared to $12.1 million for the same period in 2010. As a percentage of revenues, SG&A expenses decreased to 10.6% compared to 10.8% for the second quarter of 2010. The increase in SG&A expenses primarily resulted from higher marketing, research and development, and administrative spending needed to support revenue growth. Start-up costs of $0.4 million in 2010 related to start-up of a resin-coating plant within the Company’s existing manufacturing infrastructure at the New Iberia, Louisiana facility.

Income Tax Expense. Income tax expense was $16.2 million, or 35.2% of pretax income, for the second quarter of 2011 compared to $10.0 million, or 34.8% of pretax income, for the same period last year. The $6.2 million increase is primarily due to higher pre-tax income.

Six Months Ended June 30, 2011

Revenues. Revenues of $300.5 million for the six months ended June 30, 2011 increased 28% compared to $235.0 million in revenues for the same period in 2010. Revenues increased primarily due to a 15% increase in proppant sales volume, an increase in the average proppant selling price as a result of price increases and an increase in revenues of Falcon Technologies. Worldwide proppant sales volume totaled 785 million pounds in the first six months of 2011 compared to 684 million pounds for the same period in 2010. North American (defined as Canada and the U.S.) sales volume increased 18% due primarily to an increase in the drilling rig count in the U.S. and Canada as well as continued acceptance of the Company’s products in unconventional resource plays, including shale formations. North American proppant volumes were also favorably impacted by the availability of additional product from the Company’s recently completed third manufacturing line in Toomsboro, Georgia and increases in sales of other proppants, including CARBOBond^® resin-coated sand and ceramic proppant that meets API and ISO standards and is manufactured on an outsourced basis. International (excluding Canada) sales volumes remained relatively flat as increases in China were offset by decreases in other areas. The average selling price per pound of ceramic proppant was $0.353 during the six months ended June 30, 2011 compared to $0.317 for the same period in 2010.

Gross Profit. Gross profit for the six months ended June 30, 2011 was $124.2 million, or 41% of revenues, compared to $83.8 million, or 36% of revenues, for the same period in 2010. The increase in gross profit, as well as gross profit as a percentage of revenues, were primarily the result of higher proppant sales volume, an increase in the average proppant selling price, a change in product mix and greater contribution from Falcon Technologies, partially offset by an increase in freight costs.

Selling, General and Administrative (SG&A) and Other Operating Expenses. SG&A expenses totaled $30.1 million for the six months ended June 30, 2011 compared to $25.7 million for the same period in 2010. As a percentage of revenues, SG&A expenses decreased to 10.0% compared to 10.9% for the same six-month period in 2010. The increase in SG&A expenses primarily resulted from higher marketing, research and development, and administrative spending associated with supporting revenue growth. Start-up costs of $0.5 million in 2010 related to the start-up of the resin-coating plant within the Company’s existing manufacturing infrastructure at the New Iberia, Louisiana facility. Loss on disposal or impairment of assets of $1.6 million in 2011 consists primarily of a $0.9 million impairment of goodwill related to the Company’s geotechnical monitoring business and a $0.8 million write-down of a 6% interest in an investment accounted for under the cost method as a result of the sale of the business by majority shareholders.

Other Income (Expense). Other expense for the six months ended June 30, 2011 increased $0.2 million compared to the same period in 2010. This increase is mainly attributed to losses resulting from changes in exchange rates between the functional currency and the foreign currency in which the effective transactions were denominated.

Income Tax Expense. Income tax expense was $31.9 million, or 34.7% of pretax income, for the six months ended June 30, 2011 compared to $19.7 million, or 34.3% of pretax income for the same period last year. The $12.2 million increase is primarily due to higher pre-tax income.

Liquidity and Capital Resources

At June 30, 2011, the Company had cash and cash equivalents of $53.3 million compared to cash and cash equivalents of $46.7 million at December 31, 2010. For the six months ended June 30, 2011, the Company generated $52.1 million of cash from operating activities, $1.3 million from excess tax benefits relating to stock based compensation, received $0.1 million proceeds from exercises of stock options and retained $0.7 million from the effect of exchange rate changes on cash. Uses of cash included $37.5 million of capital spending, $9.3 million of cash dividends, and $0.8 million for the repurchase of the Company’s common stock made in connection with the payment of payroll-related taxes upon the vesting of restricted stock awards.

11

The Company believes its operating results for the remainder of 2011 will continue to be influenced by the level of oil and natural gas drilling in North America. While natural gas prices remain low, the continuing shift in oilfield activity by the Company’s clients to oily, liquids-rich plays will likely keep industry activity at high levels for the remainder of 2011. Accordingly, the Company believes proppant sales volumes will closely match productive capacity for the third quarter. The Company expects to support demand increases by pursuing capacity additions in both ceramic and resin-coated sand proppant. During periods of high demand, and at the request of its customers, the Company may also continue to engage in the sale of ceramic proppant that meets API/ISO standards manufactured on an outsourced basis.

Subject to the Company’s financial condition, the amount of funds generated from operations and the level of capital expenditures, the Company’s current intention is to continue to pay quarterly dividends to holders of its common stock. On July 19, 2011, the Board of Directors declared a cash dividend of $0.24 per common share, or $5.5 million in the aggregate, to shareholders of record on August 1, 2011. That dividend is payable on August 15, 2011. The Company estimates its total capital expenditures for the remainder of 2011 will be between $80 million and $90 million. Capital expenditures for the remainder of 2011 are expected to include costs associated with completion of the previously announced construction of the Company’s fourth production line at its Toomsboro, Georgia facility, a second resin coating line at the Company’s New Iberia facility and further resin coating expansion at the Company’s recently acquired Marshfield, Wisconsin location. The Company anticipates that the Toomsboro project will be completed near the beginning of the fourth quarter of 2011 and the New Iberia project will be completed before the end of 2011, while the Marshfield expansion will be completed by the end of 2012.

The Company maintains an unsecured line of credit of $10.0 million with Wells Fargo Bank, N.A. As of June 30, 2011, there was no outstanding debt under the new credit agreement. The Company anticipates that cash on hand, cash provided by operating activities and funds available under its line of credit will be sufficient to meet planned operating expenses, tax obligations, capital expenditures and other cash needs for the next 12 months. The Company also believes that it could acquire additional debt financing, if needed. Based on these assumptions, the Company believes that its fixed costs could be met even with a moderate decrease in demand for the Company’s products.

Off-Balance Sheet Arrangements

The Company had no off-balance sheet arrangements as of June 30, 2011.

Forward-Looking Information

The statements in this Form 10-Q that are not historical statements, including statements regarding our future financial and operating performance and liquidity and capital resources, are forward-looking statements within the meaning of the federal securities laws. All forward-looking statements are based on management’s current expectations and estimates, which involve risks and uncertainties that could cause actual results to differ materially from those expressed in the forward-looking statements. Among these factors are:

• changes in overall economic conditions,

• changes in the cost of raw materials and natural gas used in manufacturing our products,

• changes in demand and prices charged for our products,

• changes in the demand for, or price of, oil and natural gas,

• risks of increased competition,

• technological, manufacturing and product development risks,

• loss of key customers,

• changes in foreign and domestic government regulations, including environmental restrictions on operations and regulation of hydraulic fracturing,

• changes in foreign and domestic political and legislative risks,

• the risks of war and international and domestic terrorism,

• risks associated with foreign operations and foreign currency exchange rates and controls, and

• weather-related risks and other risks and uncertainties.

Additional factors that could affect our future results or events are described from time to time in our reports filed with the Securities and Exchange Commission (the “SEC”). See in particular our annual report on Form 10-K for the fiscal year ended December 31, 2010 under the caption “Risk Factors” and similar disclosures in subsequently filed reports with the SEC. We assume no obligation to update forward-looking statements, except as required by law.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company’s major market risk exposure is to foreign currency fluctuations that could impact its investments in China and Russia. As of June 30, 2011, the Company’s net investment that is subject to foreign currency fluctuations totaled $88.5 million and the Company has recorded cumulative foreign currency translation income of $0.3 million, net of deferred income tax expense. This cumulative translation income is included in Accumulated Other Comprehensive Income (Loss). From time to time, the Company may enter into forward foreign exchange contracts to hedge the impact of foreign currency fluctuations. There were no such foreign exchange contracts outstanding at June 30, 2011.

ITEM 4. CONTROLS AND PROCEDURES

(a) Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures are designed to ensure that information required to be disclosed in the reports filed or submitted under the Securities Exchange Act of 1934 (the “Exchange Act”) is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in the reports filed under the Exchange Act is accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

As of June 30, 2011, management carried out an evaluation, under the supervision and with the participation of the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurances of achieving their control objectives. Based upon and as of the date of that evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that the Company’s disclosure controls and procedures were effective to ensure that information required to be disclosed by the Company in the reports it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms, and to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the Company’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

(b) Changes in Internal Control over Financial Reporting

There were no changes in the Company’s internal control over financial reporting during the quarter ended June 30, 2011, that materially affected, or are reasonably likely to materially affect, those controls.

9. New Accounting Pronouncements

In December 2010, the Financial Accounting Standards Board (“FASB”) issued authoritative guidance on application of goodwill impairment model when a reporting unit has a zero or negative carrying amount. When a reporting unit has a zero or negative carrying value, Step 2 of the goodwill impairment test should be performed if qualitative factors indicate that it is more likely than not that a goodwill impairment exists. The guidance is effective for the Company beginning in the first quarter of fiscal 2012. The Company is currently evaluating the potential impact, if any, of the adoption of this guidance on its consolidated financial statements.

In December 2010, the FASB issued authoritative guidance on disclosure of supplementary pro forma information for business combinations. The new guidance requires that pro forma financial information should be prepared as if the business combination occurred as of the beginning of the prior annual period. The guidance is effective for the Company for business combinations with acquisition dates occurring in and from the first quarter of fiscal 2012.

In June 2011, the FASB issued ASU No. 2011-05, “Comprehensive Income (ASC Topic 220): Presentation of Comprehensive Income,” (“ASU 2011-05”) which amends current comprehensive income guidance. This accounting update eliminates the option to present the components of other comprehensive income as part of the statement of shareholders’ equity. Instead, the Company must report comprehensive income in either a single continuous statement of comprehensive income which contains two sections, net income and other comprehensive income, or in two separate but consecutive statements. ASU 2011-05 will be effective for public companies during the interim and annual periods beginning after Dec. 15, 2011 with early adoption permitted. The adoption of ASU 2011-05 will not have an impact on the Company’s consolidated financial position, results of operations or cash flows as it only requires a change in the format of the current presentation.

Stock Based Compensation

6. Stock Based Compensation

The CARBO Ceramics Inc. Omnibus Incentive Plan (the “Omnibus Incentive Plan”), which replaced the previously expired restricted stock and stock option plans, provides for granting of cash-based awards, stock options (both non-qualified and incentive) and other equity-based awards (including stock appreciation rights, phantom stock, restricted stock, restricted stock units, performance shares, deferred share units or share-denominated performance units) to employees and non-employee directors. The amount paid under the Omnibus Incentive Plan to any single participant in any calendar year with respect to any cash-based award shall not exceed $2,000. Awards may be granted with respect to a number of shares of the Company’s Common Stock that in the aggregate does not exceed 750,000 shares prior to the fifth anniversary of its effective date, plus (i) the number of shares that are forfeited, cancelled or returned, and (ii) the number of shares that are withheld from the participants to satisfy an option exercise price or minimum statutory tax withholding obligations. No more than 50,000 shares may be granted to any single participant in any calendar year. Equity-based awards may be subject to performance-based and/or service-based conditions. With respect to stock options and stock appreciation rights granted, the exercise price shall not be less than the market value of the underlying Common Stock on the date of grant. The maximum term of an option is ten years. Restricted stock awards granted generally vest (i.e., transfer and forfeiture restrictions on these shares are lifted) proportionately on each of the first three anniversaries of the grant date, but subject to certain limitations, awards may specify other vesting periods. As of June 30, 2011, 615,186 shares were available for issuance under the Omnibus Incentive Plan. Although the Company’s previous restricted stock and stock option plans have expired, outstanding options and unvested shares granted under these plans remain outstanding in accordance with their terms.

The Company also had a Director Deferred Fee Plan (the “Plan”), which terminated on January 19, 2010, that permitted non-employee directors of the Company to defer receipt of cash compensation for service as a director and to receive those fees in the form of the Company’s Common Stock on a specified later date that was on or after the director’s retirement from the Board of Directors. In January 2011, a total of 4,058 shares were issued in full payment of $171 of deferred fees remaining under the Plan to electing directors.

A summary of stock option activity and related information for the six months ended June 30, 2011 is presented below:

	Options	Weighted- Average Exercise Price	Aggregate Intrinsic Value
Outstanding at January 1, 2011	5,900	$22.04
Granted	—	—
Exercised	(3,475)	$21.83

Exercisable at June 30, 2011	2,425	$22.35	$341

As of June 30, 2011, all compensation cost related to stock options granted under the expired stock option plans has been recognized. The weighted-average remaining contractual term of options outstanding at June 30, 2011 was 1.3 years. The total intrinsic value of options exercised during the six months ended June 30, 2011 was $346.

A summary of restricted stock activity and related information for the six months ended June 30, 2011 is presented below:

	Shares	Weighted- Average Grant- Date Fair Value
Nonvested at January 1, 2011	134,276	$  51.20
Granted	54,740	$104.07
Vested	(53,321)	$  47.01
Forfeited	(2,006)	$  75.91
Nonvested at June 30, 2011	133,689	$  74.15

As of June 30, 2011, there was $6,684 of total unrecognized compensation cost, net of estimated forfeitures, related to restricted shares granted under the restricted stock plans. That cost is expected to be recognized over a weighted-average period of 1.7 years. The total fair value of shares vested during the six months ended June 30, 2011 was $2,507.

The Company also had an International Long-Term Incentive Plan that provided for granting units of stock appreciation rights (“SARs”) or phantom shares to key international employees. This plan was replaced by the Omnibus Incentive Plan. One-third of the units subject to an award vests and ceases to be forfeitable on each of the first three anniversaries of the grant date. Participants awarded units of SARs have the right to receive an amount, in cash, equal to the excess of the fair market value of a share of Common Stock as of the vesting date, or in some cases on a later exercise date chosen by the participant, over the exercise price. Participants awarded units of phantom shares are entitled to a lump sum cash payment equal to the fair market value of a share of Common Stock on the vesting date. In no event will Common Stock of the Company be issued under either plan with regard to outstanding SARs or phantom shares. As of June 30, 2011, there were 21,565 units of phantom shares granted under the plans, of which 12,153 have vested and 790 have been forfeited, with a total value of $1,405, the vested portion of which is recorded as a liability within Other Accrued Expenses.
