NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

1.    Basis of Presentation and Significant Accounting Policies

The Condensed Consolidated Financial Statements of IDEX Corporation (“IDEX” or the “Company”) have been prepared in accordance with the instructions to Form 10-Q under the Securities Exchange Act of 1934, as amended. The statements are unaudited but include all adjustments, consisting only of recurring items, except as noted, that the Company considers necessary for a fair presentation of the information set forth herein. The results of operations for the three months ended March 31, 2012 are not necessarily indicative of the results to be expected for the entire year.

The condensed consolidated financial statements and Management’s Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2011.

Adoption of New Accounting Standards

In May 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2011-04 which was issued to provide a consistent definition of fair value and ensure that the fair value measurement and disclosure requirements are similar between U.S. Generally Accepted Accounting Principles (“GAAP”) and International Financial Reporting Standards (“IFRS”). ASU 2011-04 changes certain fair value measurement principles and enhances the disclosure requirements particularly for Level 3 fair value measurements. The Company adopted this guidance on January 1, 2012, and its adoption did not impact the consolidated financial position, results of operations or cash flows of the Company.

In June 2011, FASB issued ASU 2011-05 “Presentation of Comprehensive Income” (“ASU 2011-05”). ASU 2011-05 allows an entity to present components of net income and other comprehensive income in one continuous statement, referred to as the statement of comprehensive income, or in two separate, but consecutive statements. The new guidance eliminates the current option to report other comprehensive income and its components in the statement of changes in equity. While ASU 2011-05 changes the presentation of comprehensive income, there are no changes to the components that are recognized in net income or other comprehensive income under current accounting guidance. In December 2011, FASB issued ASU 2011-12 “Comprehensive Income (Topic 220); Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05” (“ASU 2011-12”). ASU 2011-12 deferred certain aspects of ASU 2011-05. The new guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. The adoption of ASU 2011-05 and the deferrals in ASU 2011-12 did not impact the consolidated financial position, results of operations or cash flows of the Company.

2.    Restructuring

During 2011, the Company began recording restructuring costs as a result of initiatives that support the implementation of key strategic efforts designed to facilitate long-term sustainable growth through cost reduction actions, primarily consisting of employee reductions and facility rationalization. The costs incurred related to these initiatives are included in Restructuring expenses in the Consolidated Statements of Operations while the restructuring accruals are included in Accrued expenses in our Consolidated Balance Sheets.

During the three months ended March 31, 2012, the Company recorded $4.9 million of pre-tax restructuring expenses related to its 2011 restructuring initiative for employee severance related to employee reductions across various functional areas as well as facility rationalization. The 2011 restructuring initiatives included severance benefits for 337 employees.

5.    Earnings Per Common Share

Earnings per common share (“EPS”) are computed by dividing net income by the weighted average number of shares of common stock (basic) plus common stock equivalents outstanding (diluted) during the period. Common stock equivalents consist of stock options, which have been included in the calculation of weighted average shares outstanding using the treasury stock method, unvested shares, and shares issuable in connection with certain deferred compensation agreements (“DCUs”).

ASC 260 “Earnings Per Share”, concludes that all outstanding unvested share-based payment awards that contain rights to nonforfeitable dividends participate in undistributed earnings with common shareholders. If awards are considered participating securities, the Company is required to apply the two-class method of computing basic and diluted earnings per share. The Company has determined that its outstanding unvested shares are participating securities. Accordingly, earnings per common share are computed using the two-class method prescribed by ASC 260. Net income attributable to common shareholders was reduced by $0.2 million and $0.4 million for the three months ended March 31, 2012 and 2011, respectively.

Basic weighted average shares reconciles to diluted weighted average shares as follows:

	Three Months Ended March 31,
	2012		2011
	(In thousands)
Basic weighted average common shares outstanding		82,804		81,430
Dilutive effect of stock options, unvested shares, and DCUs		1,098		1,818
Diluted weighted average common shares outstanding		83,902		83,248

Options to purchase approximately 1.3 million and 0.7 million shares of common stock for the three months ended March 31, 2012 and 2011, respectively, were not included in the computation of diluted EPS because the exercise price was greater than the average market price of the Company’s common stock and, therefore, the effect of their inclusion would be antidilutive.

6.    Inventories

The components of inventories as of March 31, 2012 and December 31, 2011 were:

	March 31, 2012		December 31, 2011
	(In thousands)
Raw materials and component parts	$	155,253	$	155,577

Total	$	253,564	$	254,258

Inventories are stated at the lower of cost or market. Cost, which includes material, labor, and factory overhead, is determined on a FIFO basis.

7.    Goodwill and Intangible Assets

The changes in the carrying amount of goodwill for the three months ended March 31, 2012, by reportable business segment, were as follows:

	Fluid & Metering Technologies		Health & Science Technologies		Fire &  Safety/ Diversified Products		Total
Balance at December 31, 2011(1)	$	541,640	$	648,906	$	240,820	$	1,431,366
Acquisition adjustments		—		1,424		—		1,424
Foreign currency translation		3,856		1,511		4,003		9,370
Balance at March 31, 2012	$	545,496	$	651,841	$	244,823	$	1,442,160

(1) Revised to reflect the movement of the Dispensing Equipment segment to the Fire & Safety/Diversified Products segment and the transfer of $20.6 million of goodwill related to the movement of our Trebor business unit within the Health & Science Technologies segment to the Fluid & Metering Technologies segment.

ASC 350 “Goodwill and Other Intangible Assets” requires that goodwill be tested for impairment at the reporting unit level on an annual basis and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of the reporting unit below its carrying value. Annually on October 31, goodwill and other acquired intangible assets with indefinite lives are tested for impairment. The Company concluded that the fair value of each of the reporting units was in excess of the carrying value as of October 31, 2011. The Company did not consider there to be any triggering event that would require an interim impairment assessment, therefore none of the goodwill or other acquired intangible assets with indefinite lives were tested for impairment during the three months ended March 31, 2012.

The following table provides the gross carrying value and accumulated amortization for each major class of intangible asset at March 31, 2012 and December 31, 2011:

10.    Borrowings

Borrowings at March 31, 2012 and December 31, 2011 consisted of the following:

	March 31, 2012		December 31, 2011
	(In thousands)
Revolving Facility	$	11,181	$	50,798
4.2% Senior Notes, due December 2021		349,143		349,125
4.5% Senior Notes, due December 2020		298,588		298,555

Less current portion		3,796		2,444
Total long-term borrowings	$	769,850	$	806,366

On June 27, 2011, the Company entered into a credit agreement (the “Credit Agreement”) along with certain of its subsidiaries, as borrowers (the “Borrowers”), with Bank of America, N.A., as administrative agent, swing line lender and an issuer of letters of credit, and other lenders party thereto. The Credit Agreement replaced the Company’s previous $600.0 million credit facility, which was due to expire in December 2011.

The Credit Agreement consists of a revolving Credit Facility in an aggregate principal amount of $700.0 million with a maturity date of June 27, 2016. The maturity date may be extended under certain conditions for an additional one-year term prior to the second anniversary of the initial closing date of June 27, 2011. Up to $75.0 million of the Revolving Facility is available for the issuance of letters of credit. Additionally, up to $25.0 million of the Revolving Facility is available to the Company for swing line loans, available on a same-day basis.

Proceeds of the Revolving Facility are available for use by the Borrowers for working capital and other general corporate purposes, including refinancing existing debt of the Company and its subsidiaries. The Company may request increases in the lending commitments under the Credit Agreement, but the aggregate lending commitments may not exceed $950.0 million. The Company has the right, subject to certain conditions set forth in the Credit Agreement, to designate certain foreign subsidiaries of the Company as borrowers under the Credit Agreement. In connection with any such designation, the Company is required to guarantee the obligations of any such subsidiaries under the Credit Agreement. Under the Credit Agreement, Fluid Management Europe B.V., (“FME”) and IDEX UK Ltd. (“IDEX UK”) were approved by the lenders as designated borrowers. At March 31, 2012, FME had no borrowings under the Revolving Facility, while IDEX UK’s borrowings under the Revolving Facility were £2.0 million ($3.2 million). As IDEX UK’s borrowings under the Revolving Facility are British Pound denominated and the cash flows that will be used to make payments of principal and interest are predominately generated in British Pounds, the Company does not anticipate any significant foreign exchange gains or losses in servicing this debt.

Borrowings under the Revolving Facility bear interest, at either an alternate base rate or an adjusted LIBOR rate plus, an applicable margin. Such applicable margin is based on the Company’s senior, unsecured, long-term debt rating and can range from .875% to 1.70%. Based on the Company’s credit rating at March 31, 2012, the applicable margin was 1.05%. Interest is payable (a) in the case of base rate loans, quarterly, and (b) in the case of LIBOR rate loans, on the maturity date of the borrowing, or quarterly from the effective date for borrowings exceeding three months. An annual Revolving Facility fee, also based on the Company’s credit rating, is currently 20 basis points and is payable quarterly.

The Credit Agreement contains affirmative and negative covenants that the Company believes are usual and customary for senior unsecured credit agreements, including a financial covenant requiring the maintenance of a 3.25 to 1.0 or lower leverage ratio, which is the ratio of the Company’s consolidated total debt to its consolidated EBITDA, each as defined in the Credit Agreement.

The Credit Agreement also contains customary events of default (subject to grace periods, as appropriate) including among others: nonpayment of principal, interest or fees; breach of the representations or warranties in any material respect; breach of the financial, affirmative or negative covenants; payment default on, or acceleration of, other material indebtedness; bankruptcy or insolvency; material judgments entered against the Company or any of its subsidiaries; certain specified events under the Employee Retirement Income Security Act of 1974, as amended; certain changes in control of the Company; and the invalidity or unenforceability of the Credit Agreement or other documents associated with the Credit Agreement.

At March 31, 2012, there was $11.2 million outstanding under the Revolving Facility with $7.0 million of outstanding letters of credit. The net available borrowing capacity under the Revolving Facility at March 31, 2012, was approximately $681.8 million.

On June 9, 2010, the Company completed a private placement of €81.0 million ($96.8 million) aggregate principal amount of 2.58% Series 2010 Senior Euro Notes due June 9, 2015 (“2.58% Senior Euro Notes”) pursuant to a Master Note Purchase Agreement, dated June 9, 2010 (the “Purchase Agreement”). The Purchase Agreement provides for the issuance of additional series of notes in the future, provided that the aggregate principal amount outstanding under the agreement at any time does not exceed $750.0 million. The 2.58% Senior Euro Notes bear interest at a rate of 2.58% per annum, which is payable semi-annually in arrears on each June 9^th and December 9^th and will mature on June 9, 2015. The 2.58% Senior Euro Notes are unsecured obligations of the Company and rank pari passu in right of payment with all of the Company’s other senior debt. The Company may at any time prepay all or any portion of the 2.58% Senior Euro Notes; provided that any such portion is greater than 5% of the aggregate principal amount of Notes then outstanding under the Purchase Agreement. In the event of a prepayment, the Company would be required to pay an amount equal to par plus accrued interest plus a make-whole premium. The Purchase Agreement contains certain covenants that restrict the Company’s ability to, among other things, transfer or sell assets, create liens and engage in certain mergers or consolidations. In addition, the Company must comply with a leverage ratio and interest coverage ratio as set forth in the Purchase Agreement. The Purchase Agreement provides for customary events of default. In the case of an event of default arising from specified events of bankruptcy or insolvency, all outstanding 2.58% Senior Euro Notes will become due and payable immediately without further action or notice. In the case of payment events of defaults, any holder of the 2.58% Senior Euro Notes affected thereby may declare all the 2.58% Senior Euro Notes held by it due and payable immediately. In the case of any other event of default, a majority of the holders of the 2.58% Senior Euro Notes may declare all the 2.58% Senior Euro Notes to be due and payable immediately.

On December 6, 2010, the Company completed a public offering of $300.0 million 4.5% senior notes due December 15, 2020 (“4.5% Senior Notes”). The net proceeds from the offering of $295.7 million, after deducting the $1.6 million issuance discount, the $1.9 million underwriting commission and $0.8 million offering expenses, were used to repay $250.0 million of outstanding bank indebtedness, with the balance used for general corporate purposes. The 4.5% Senior Notes bear interest at a rate of 4.5% per annum, which is payable semi-annually in arrears on each June 15^th and December 15^th. The Company may redeem all or a portion of the 4.5% Senior Notes at any time prior to maturity at the redemption prices set forth in the Note Indenture governing the 4.5% Senior Notes. The Company may issue additional debt from time to time pursuant to the Indenture. The Indenture and 4.5% Senior Notes contain covenants that limit the Company’s ability to, among other things, incur certain liens securing indebtedness, engage in certain sale-leaseback transactions, and enter into certain

14

IDEX CORPORATION AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

(unaudited)

consolidations, mergers, conveyances, transfers or leases of all or substantially all the Company’s assets. The terms of the 4.5% Senior Notes also require the Company to make an offer to repurchase the 4.5% Senior Notes upon a change of control triggering event (as defined in the Indenture) at a price equal to 101% of their principal amount plus accrued and unpaid interest, if any.

On December 9, 2011, the Company completed a public offering of $350.0 million 4.2% senior notes due December 15, 2021 (“4.2% Senior Notes”). The net proceeds from the offering of $346.2 million, after deducting the $0.9 million issuance discount, the $2.3 million underwriting commission and $0.6 million offering expenses, were used to repay $306.0 million of outstanding bank indebtedness, with the balance used for general corporate purposes. The 4.2% Senior Notes bear interest at a rate of 4.2% per annum, which is payable semi-annually in arrears on each June 15^th and December 15^th. The Company may redeem all or a portion of the 4.2% Senior Notes at any time prior to maturity at the redemption prices set forth in the Note Indenture governing the 4.2% Senior Notes. The Company may issue additional debt from time to time pursuant to the Indenture. The Indenture and 4.2% Senior Notes contain covenants that limit the Company’s ability to, among other things, incur certain liens securing indebtedness, engage in certain sale-leaseback transactions, and enter into certain consolidations, mergers, conveyances, transfers or leases of all or substantially all the Company’s assets. The terms of the 4.2% Senior Notes also require the Company to make an offer to repurchase the 4.2% Senior Notes upon a change of control triggering event (as defined in the Indenture) at a price equal to 101% of their principal amount plus accrued and unpaid interest, if any.

Other borrowings of $7.0 million at March 31, 2012 were comprised of capital leases as well as debt at international locations maintained for working capital purposes. Interest is payable on the outstanding debt balances at the international locations at rates ranging from 1.5% to 5.2% per annum.

There are two key financial covenants that the Company is required to maintain in connection with the Revolving Facility and 2.58% Senior Euro Notes. The most restrictive financial covenants under these debt instruments require a minimum interest coverage ratio of 3.0 to 1 and a maximum leverage ratio of 3.25 to 1. At March 31, 2012, the Company was in compliance with both of these financial covenants. There are no financial covenants relating to the 4.5% Senior Notes or 4.2% Senior Notes.

11.    Derivative Instruments

The Company enters into cash flow hedges to reduce the exposure to variability in certain expected future cash flows. The type of cash flow hedges the Company enters into includes foreign currency contracts and interest rate exchange agreements that effectively convert a portion of floating-rate debt to fixed-rate debt and are designed to reduce the impact of interest rate changes on future interest expense.

The effective portion of gains or losses on interest rate exchange agreements is reported in accumulated other comprehensive income (loss) in shareholders’ equity and reclassified into net income in the same period or periods in which the hedged transaction affects net income. The remaining gain or loss in excess of the cumulative change in the present value of future cash flows or the hedged item, if any, is recognized into net income during the period of change.

Fair values relating to derivative financial instruments reflect the estimated amounts that the Company would receive or pay to sell or buy the contracts based on quoted market prices of comparable contracts at each balance sheet date.

On April 15, 2010, the Company entered into a forward starting interest rate contract with a notional amount of $300.0 million with a settlement date in December 2010. This contract was entered into in anticipation of the

15

IDEX CORPORATION AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

(unaudited)

issuance of the 4.5% Senior Notes and was designed to lock in the market interest rate as of April 15, 2010. In December 2010, the Company settled and paid this interest rate contract for $31.0 million. The $31.0 million is being amortized into interest expense over the 10 year term of the 4.5% Senior Notes, which results in an effective interest rate of 5.8%.

On July 12, 2011, the Company entered into a forward starting interest rate contract with a notional amount of $350.0 million and a settlement date of September 30, 2011. This contract was entered into in anticipation of the issuance of the 4.2% Senior Notes and was designed to lock in the market interest rate as of July 12, 2011. On September 29, 2011, the Company settled this interest rate contract for $34.7 million with a payment made on October 3, 2011. Simultaneously, the Company entered into a separate interest rate contract with a notional amount of $350.0 million and a settlement date of February 28, 2012. The contract was entered into in anticipation of the expected issuance of the 4.2% Senior Notes and was designed to maintain the market rate as of July 12, 2011. In December 2011, the Company settled and paid the September interest rate contract for $4.0 million, resulting in a total settlement of $38.7 million. Of the $38.7 million, $0.8 was recognized as other expense in 2011 and the balance of $37.9 million is being amortized into interest expense over the 10 year term of the 4.2% Senior Notes, which results in an effective interest rate of 5.3%.

As of March 31, 2012, the Company did not have any interest rate contracts outstanding.

The following table summarizes the gain (loss) recognized and the amounts and location of income (expense) and gain (loss) reclassified into income for interest rate contracts and foreign currency contracts for March 31, 2012 and 2011:

	Gain (Loss) Recognized  in Other Comprehensive Income					(Expense) and Gain Reclassified into Income
	Three Months Ended March 31,											Income Statement Caption

Interest rate agreements	$	—	$	955		$	(1,925	)	$	(1,560	)		Interest expense
Foreign exchange contracts		—		(55	)		—			120			Sales

Approximately $7.6 million of the pre-tax amount included in accumulated other comprehensive income (loss) in shareholders’ equity at March 31, 2012 will be recognized to net income over the next 12 months as the underlying hedged transactions are realized.

12.    Fair Value Measurements

ASC 820 “Fair Value Measurements and Disclosures” defines fair value, provides guidance for measuring fair value and requires certain disclosures. This standard discusses valuation techniques, such as the market approach (comparable market prices), the income approach (present value of future income or cash flow), and the cost approach (cost to replace the service capacity of an asset or replacement cost). The standard utilizes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The following is a brief description of those three levels:

• Level 1: Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities.

16

IDEX CORPORATION AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

(unaudited)

• Level 2: Inputs, other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active.

• Level 3: Unobservable inputs that reflect the reporting entity’s own assumptions.

The following table summarizes the basis used to measure the Company’s financial assets and (liabilities) at fair value on a recurring basis in the balance sheet at March 31, 2012 and December 31, 2011:

	Basis of Fair Value Measurements
	Balance at March 31,  2012			Level 1		Level 2		Level 3
	(In thousands)
Money market investment	$	15,402		$	15,402	$	—	$	—
Available for sale securities		3,326			3,326		—		—
Contingent consideration		(1,500	)		—		—		(1,500	)

	Basis of Fair Value Measurements
	Balance at December 31, 2011			Level 1		Level 2		Level 3
	(In thousands)
Money market investment	$	11,899		$	11,899	$	—	$	—
Available for sale securities		2,785			2,785		—		—
Contingent consideration		(3,000	)		—		—		(3,000	)

There were no transfers of assets or liabilities between Level 1 and Level 2 during the first three months of 2012 or 2011.

In determining the fair value of the Company’s contingent consideration upon acquisition of AT Films, the Company used a probability weighted estimate adjusted for the time value of money. In February 2012, the Company paid $1.5 million on the contingent consideration arrangement. The maximum remaining liability is $1.5 million, which is reflected in Accrued expenses and is expected to be paid in the first quarter of 2013.

The carrying value of our cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximates their fair values because of the short term nature of these instruments. At March 31, 2012, the fair value of our Revolving Facility, 2.58% Senior Euro Notes, 4.5% Senior Notes and 4.2% Senior Notes, based on quoted market prices and current market rates for debt with similar credit risk and maturity, was approximately $785.5 million compared to the carrying value of $766.7 million. This fair value measurement is classified as Level 2 within the fair value hierarchy since it is determined based upon significant inputs observable in the market, including interest rates on recent financing transactions to entities with a credit rating similar to ours.

13.    Common and Preferred Stock

On December 6, 2011, the Company announced that its Board of Directors increased the authorized level for repurchases of its common stock by approximately $50.0 million. The increased authorization will be added to the approximately $75.0 million that remains available from the existing authorization approved by the Board of Directors on April 21, 2008, resulting in a total authorized repurchase amount of $125.0 million. Since the inception of this program, the Company has purchased a total of 0.2 million shares at a cost of approximately $10.2 million.

17

IDEX CORPORATION AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

(unaudited)

At March 31, 2012 and December 31, 2011, the Company had 150 million shares of authorized common stock, with a par value of $.01 per share, and 5 million shares of authorized preferred stock, with a par value of $.01 per share. No preferred stock was issued at March 31, 2012 and December 31, 2011.

14.    Share-Based Compensation

During the three months ended for both March 31, 2012 and 2011, the Company granted approximately 0.7 million stock options and 0.2 million unvested shares, respectively.

Weighted average option fair values and assumptions for the periods specified are disclosed in the following table:

	Three Months Ended March 31,
	2012	2011
Weighted average fair value of option grants	$11.47	$12.34
Dividend yield	1.57%	1.46%
Volatility	32.01%	32.76%
Risk-free forward interest rate	0.17% - 3.98%	0.28% - 5.62%
Expected life (in years)	5.98	6.18

The assumptions are as follows:

• The Company estimated volatility using its historical share price performance over the contractual term of the option.

• The Company uses historical data to estimate the expected life of the option. The expected life assumption for the three months ended March 31, 2012 and 2011 is an output of the Binomial lattice option-pricing model, which incorporates vesting provisions, rate of voluntary exercise and rate of post-vesting termination over the contractual life of the option to define expected employee behavior.

• The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for periods within the contractual life of the option. For the three months ended March 31, 2012 and 2011, we present the range of risk-free one-year forward rates, derived from the U.S. treasury yield curve, utilized in the Binomial lattice option-pricing model.

• The expected dividend yield is based on the Company’s current dividend yield as the best estimate of projected dividend yield for periods within the contractual life of the option.

The Company’s policy is to recognize compensation cost on a straight-line basis over the requisite service period for the entire award. Additionally, the Company’s general policy is to issue authorized and unissued shares of common stock to satisfy stock option exercises or grants of unvested shares.

As of March 31, 2012, there was $12.6 million of total unrecognized compensation cost related to stock options that is expected to be recognized over a weighted-average period of 1.6 years, and $14.0 million of total unrecognized compensation cost related to unvested shares that is expected to be recognized over a weighted-average period of 1.3 years.

The Company previously disclosed in its financial statements for the year ended December 31, 2011, that it expected to contribute approximately $9.4 million to its pension plans and $0.9 million to its other postretirement benefit plans in 2012. As of March 31, 2012, $3.6 million of contributions have been made to the pension plans and $0.1 million have been made to its other postretirement benefit plans. The Company presently anticipates contributing up to an additional $6.6 million in 2012 to fund its pension plans and other postretirement benefit plans.

16.    Legal Proceedings

The Company is party to various legal proceedings arising in the ordinary course of business, none of which are expected to have a material adverse effect on its business, financial condition, results of operations or cash flows.

17.    Income Taxes

The Company’s provision for income taxes is based upon estimated annual tax rates for the year applied to federal, state and foreign income. The provision for income taxes decreased to $21.9 million in the first quarter of 2012 from $22.4 million in the first quarter of 2011. The effective tax rate decreased to 29.5% for the first quarter of 2012 compared to 31.8% in the first quarter of 2011 due to the mix of global pre-tax income among jurisdictions, a decrease in the amount of disallowed executive compensation expense and as a result of recent acquisitions.

The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction, and various state and foreign jurisdictions. Due to the potential for resolution of federal, state and foreign examinations, and the expiration of various statutes of limitation, it is reasonably possible that the Company’s gross unrecognized tax benefits balance may change within the next twelve months by a range of zero to $1.6 million.

18.    Subsequent Events

On April 11, 2012, the Company acquired Precision Photonics Corporation (“PPC”) for cash consideration of approximately $20.5 million. PPC, located in Boulder, Colorado, specializes in optical components and coatings for applications in the fields of scientific research, aerospace, telecommunications and electronics manufacturing. PPC will operate as part of the Optics and Photonics platform within the Health & Science Technologies Segment.

On April 30, 2012, the Company acquired ERC for cash consideration of approximately $20.0 million (¥1.65 billion) from MH Capital Partners II, L.P. ERC is a leader in the manufacture of gas liquid separations and detection solutions for the life science, analytical instrumentation and clinical chemistry markets. ERC’s pioneering products include in-line membrane vacuum degassing solutions, refractive index detectors and ozone generation systems. ERC’s original equipment degassing solutions are considered the “standard” for many of the world’s leading instrument producers. Located in Kawaguchi, Japan, ERC has annual revenues of approximately $27.0 million (¥2.14 billion) and will operate within the Health and Science Technologies Segment.

Results of Operations

The following is a discussion and analysis of our results of operations for the three month periods ended March 31, 2012 and 2011. Segment operating income excludes unallocated corporate operating expenses. Certain prior year amounts have been revised to include the Dispensing Equipment Segment as part of the Fire & Safety/Diversified Products Segment and to reflect the movement of our Trebor business unit from the Health & Science Technologies Segment to the Fluid & Metering Technologies Segment.

In this report, references to organic sales, a non-GAAP measure, refers to sales from continuing operations calculated according to generally accepted accounting principles in the United States but excludes (1) sales from acquired businesses during the first twelve months of ownership and (2) the impact of foreign currency translation. The portion of sales attributable to foreign currency translation is calculated as the difference between (a) the period-to-period change in organic sales and (b) the period-to-period change in organic sales after applying prior period foreign exchange rates to the current year period. Management believes that reporting organic sales provides useful information to investors by helping identify underlying growth trends in our business and facilitating easier comparisons of our revenue performance with prior and future periods and to our peers. The Company excludes the effect of foreign currency translation from organic sales because foreign currency translation is not under management’s control, is subject to volatility and can obscure underlying business trends. The Company excludes the effect of acquisitions because the nature, size, and number of acquisitions can vary dramatically from period to period and between the Company and its peers and can also obscure underlying business trends and make comparisons of long-term performance difficult.

Management’s primary measurement of segment performance is sales, operating income, and operating margin. In addition, due to the highly acquisitive nature of the Company, the determination of operating income includes amortization of acquired intangible assets and, as a result, management reviews depreciation and amortization as a percentage of sales. These measures are monitored by management and significant changes in operating results versus current trends in end markets and variances from forecasts are analyzed with segment management.

Consolidated Results

	Three Months Ended March 31,
	2012			2011
	(in thousands)
Net sales	$	489,417		$	427,089
Operating income		84,569			77,721
Operating margin		17.3	%		18.2	%
Depreciation and amortization	$	19,190		$	15,622
Depreciation and amortization as a percentage of net sales		3.9	%		3.7	%

Sales in the three months ended March 31, 2012 were $489.4 million, a 15% increase from the comparable period last year. This increase reflects a 6% increase in organic sales, 10% from acquisitions (AT Films —January 2011, Microfluidics — March 2011 and CVI MG — June 2011) and 1% unfavorable foreign currency translation. International sales represented approximately 52% of total sales in the current period compared with 51% in the same period in 2011.

For the first quarter of 2012, Fluid & Metering Technologies contributed 44% of sales and 46% of operating income; Health & Science Technologies accounted for 35% of sales and 31% of operating income; and Fire & Safety/Diversified Products represented 21% of sales and 23% of operating income.

22

Gross profit of $202.9 million in the first quarter of 2012 increased $24.2 million, or 14%, from 2011. Gross profit as a percent of sales, or gross margins, was 41.5% in the first quarter of 2012 and 41.8% in 2011. The decrease in gross margin primarily reflects product mix, partially offset by higher volume.

Selling, general and administrative (“SG&A”) expenses increased to $113.4 million in the first quarter of 2012 from $101.0 million in 2011. The $12.4 million increase reflects approximately $12.7 million for incremental costs from new acquisitions, partially offset by a decrease in volume related expenses of $0.3 million. As a percentage of sales, SG&A expenses were 23.2% for 2012 and 23.6% for 2011.

During the three months ended March 31, 2012, the Company recorded pre-tax restructuring expenses totaling $4.9 million. These restructuring expenses were mainly attributable to employee severance related to employee reductions across various functional areas and facility rationalization resulting from the Company’s cost savings initiatives.

Operating income of $84.6 million in the first quarter of 2012 was up from the $77.7 million recorded in 2011, primarily reflecting an increase in volume and improved productivity. Operating income as a percent of sales, or operating margin, of 17.3% in the first quarter 2012 was down from 18.2% in 2011 primarily due to increased expenses from restructuring-related charges and the dilutive impact from acquisitions, partially offset by volume leverage and productivity.

Other income of $0.1 million in 2012 was higher than the $0.9 million loss recorded in 2011, primarily due to higher losses on foreign currency transactions in 2011.

Interest expense increased to $10.7 million in 2012 from $6.5 million in 2011. The increase was principally due to higher debt levels issued in conjunction with the CVI MG acquisition and higher interest rates associated with fixed rate debt.

The provision for income taxes is based upon estimated annual tax rates for the year applied to federal, state and foreign income. The provision for income taxes decreased to $21.9 million, resulting in an effective tax rate of 29.5%, in the first quarter of 2012 compared to $22.4 million, an effective tax rate of 31.8%, in the first quarter of 2011. The decrease was due to the mix of global pre-tax income among jurisdictions as well as a decrease in the amount of disallowed executive compensation expense, and as a result of recent acquisitions.

Net income for the current quarter of $52.2 million increased from the $48.0 million earned in 2011. Diluted earnings per share in the first quarter of 2012 of $0.62 increased $0.05, or 9%, compared with 2011.

Fluid & Metering Technologies Segment

	Three Months Ended March 31,
	2012			2011
	(in thousands)
Net sales	$	212,718		$	199,674
Operating income		44,526			41,852
Operating margin		20.9	%		21.0	%
Depreciation and amortization	$	7,540		$	7,998
Depreciation and amortization as a percentage of net sales		3.5	%		4.0	%

Sales of $212.7 million increased $13.0 million, or 7% in the first quarter of 2012 compared with 2011. This reflects 8% organic growth and 1% unfavorable foreign currency translation. The increase in organic sales was largely attributed to strong growth across our Energy platform; CFP platform; and our Agricultural group. In the first quarter of 2012, organic sales increased approximately 7% domestically and 8% internationally. Organic sales to customers outside the U.S. were approximately 47% of total segment sales during the first quarter of 2012, compared with 45% in 2011.

23

Sales within our Energy platform increased compared to the first quarter of 2011, due to strong demand for systems used in upstream and downstream oil and gas applications both domestically and internationally. Additionally, large Energy project sales to emerging markets drove international sales growth, partially offset by weakness in the European downstream markets due to general economic conditions. Domestic sales growth within Energy was driven by the transportation end markets and strength in our distribution channel, partially offset by slower demand for LPG and home heating oil due to warmer climate conditions. Sales within our CFP platform increased compared to the first quarter of 2011 on strong general industrial and chemical demand in both our OEM and distributor channels in North America and Asia. In addition, CFP sales growth accelerated in emerging markets as our investments in India and China continue to pay off. Sales within our Agriculture group increased due to robust demand driven by favorable weather patterns in North America. Offsetting the sales increases above was a decrease in sales within our Water and Waste Water platform, as the platform continues to experience ongoing municipal water end market softness due to municipal funding headwinds.

Operating income of $44.5 million in the first quarter of 2012 was up from the $41.9 million recorded in 2011 principally due to volume leverage, productivity, and benefits from prior period restructuring activities. Operating margin of 20.9% in the first quarter of 2012 was down slightly from 21.0% in 2011, primarily due to $2.7 million of current period restructuring expenses and increased costs associated with service contracts.

Health & Science Technologies Segment

	Three Months Ended March 31,
	2012			2011
	(in thousands)
Net sales	$	173,786		$	129,234
Operating income		30,270			29,499
Operating margin		17.4	%		22.8	%
Depreciation and amortization	$	9,461		$	4,984
Depreciation and amortization as a percentage of net sales		5.4	%		3.9	%

Sales of $173.8 million increased $44.6 million, or 35% in the first quarter of 2012 compared with 2011. This reflects 2% organic growth and 33% growth from acquisitions (AT Films, Microfluidics and CVI MG). In the first quarter of 2012, organic sales decreased 1% domestically and increased 4% internationally. Organic sales to customers outside the U.S. were approximately 52% of total segment sales in the first quarter of 2012, compared with 48% in 2011.

Sales within our Material Process Technologies platform increased compared to the first quarter of 2011 due a full quarter of sales from Microfluidics acquired in March 2011, strength in the Asian pharmaceutical markets, and large project orders received in the second half of 2011, which shipped during the first quarter of 2012. Sales within our Scientific Fluidics platform decreased compared to the first quarter of 2011 due to slowed instrumentation end markets driven by National Institutes of Health (NIH) funding concerns and inventory reduction programs by our customers, partially offset by modest growth in the Life Sciences end market. Sales within our Containment group increased compared to the first quarter of 2011 due to strong distributor sales and an upturn in the diesel and gas engine markets. Sales within our Optics and Photonics platform increased compared to the first quarter of 2011 primarily as a result of our CVI MG acquisition. However, sales within our Optics and Photonics platform are less than anticipated due to headwinds in the defense and semiconductor end markets. Sales at our Industrial group decreased compared to the first quarter of 2011 due to lower sales to distributors and slower sales into automotive end markets.

Operating income of $30.3 million in the first quarter of 2012 was up from the $29.5 million recorded in 2011, primarily due to acquisitions and productivity from prior period restructuring actions, partially offset by $1.5 million of current period restructuring charges. Operating margin of 17.4% in the first quarter of 2012 was down from 22.8% in 2011, due to the dilutive impact from acquisitions and $1.5 million of current period restructuring charges.

Fire & Safety/Diversified Products Segment

	Three Months Ended March 31,
	2012			2011
	(in thousands)
Net sales	$	104,050		$	98,887
Operating income		23,688			21,142
Operating margin		22.8	%		21.4	%
Depreciation and amortization	$	7,540		$	7,998
Depreciation and amortization as a percentage of net sales		7.2	%		8.1	%

Sales of $104.1 million increased $5.2 million, or 5% in the first quarter of 2012 compared with the first quarter of 2011. This reflects 7% organic growth and 2% unfavorable foreign currency translation. In the first quarter of 2012, organic sales increased 20% domestically and decreased 1% internationally. Organic sales to customers outside the U.S. were approximately 60% of total segment sales in the first quarter of 2012, compared with 64% in 2011.

Sales within our Dispensing group increased on strength in our core North American markets with additional contribution from Europe and emerging markets. The sales increase within our Band-It group was driven by general North American industrial market improvement and product innovation. The Band-It group participates in diverse end markets and continues to grow faster than their served markets. Sales within our Fire Suppression group increased as a result of geographic expansions into Eastern Europe and Asian markets and through the penetration into product adjacencies. Sales within our Rescue group increased as a result of robust demand for our rescue tools within emerging markets. In addition, the North American market for rescue tools saw record sales driven by our eDraulic product introduction.

Operating income and operating margin of $23.7 million and 22.8%, respectively, were higher than the $21.1 million and 21.4% recorded in the first quarter of 2011, primarily due to volume leverage and productivity. In addition, structural actions taken over the past year have enabled margin expansion and leverage. Operating margin was negatively impacted by $0.5 million of current quarter restructuring charges related to facility rationalization within our Dispensing group.

Liquidity and Capital Resources

At March 31, 2012, working capital was $579.8 million and the current ratio was 3.3 to 1. Cash flows from operating activities for the first three months of 2012 increased $29.6 million, or 102%, to $58.7 million compared to the first three months of 2011 mainly due to increased volume.

Cash flows provided by operating activities were more than adequate to fund capital expenditures of $8.5 million and $11.4 million in the first three months of 2012 and 2011, respectively. Capital expenditures were generally for machinery and equipment that improved productivity and tooling to support the Company’s global sourcing initiatives, although a portion was for business system technology and replacement of equipment and facilities. Management believes that the Company has sufficient capacity in its plants and equipment to meet expected needs for future growth.

The Company maintains the Revolving Facility, which is a $700.0 million unsecured, multi-currency bank credit facility expiring on June 27, 2016. At March 31, 2012, there was $11.2 million outstanding under the Revolving Facility and outstanding letters of credit totaled approximately $7.0 million. The net available borrowing capacity under the Revolving Facility at March 31, 2012, was approximately $681.8 million. Borrowings under the Revolving Facility bear interest, at either an alternate base rate or an adjusted LIBOR rate plus, in each case, an applicable margin. Such applicable margin is based on the Company’s senior, unsecured, long-term debt rating and can range from .875% to 1.70%. Based on the Company’s credit rating at March 31, 2012, the applicable margin was 1.05%. Interest is payable (a) in the case of base rate loans, quarterly, and (b) in

25

the case of LIBOR rate loans, on the maturity date of the borrowing, or quarterly from the effective date for borrowings exceeding three months. An annual Revolving Facility fee, also based on the Company’s credit rating, is currently 20 basis points and is payable quarterly.

On June 9, 2010, the Company completed a private placement of €81.0 million ($96.8 million) aggregate principal amount of 2.58% Series 2010 Senior Euro Notes due June 9, 2015 (“2.58% Senior Euro Notes”) pursuant to a Master Note Purchase Agreement, dated June 9, 2010 (the “Purchase Agreement”). The Purchase Agreement provides for the issuance of additional series of notes in the future, provided that the aggregate principal amount outstanding under the agreement at any time does not exceed $750.0 million. The 2.58% Senior Euro Notes bear interest at a rate of 2.58% per annum, which is payable semi-annually in arrears on each June 9^th and December 9^th and will mature on June 9, 2015. The 2.58% Senior Euro Notes are unsecured obligations of the Company and rank pari passu in right of payment with all of the Company’s other senior debt. The Company may at any time prepay all or any portion of the 2.58% Senior Euro Notes; provided that any such portion is greater than 5% of the aggregate principal amount of Notes then outstanding under the Purchase Agreement. In the event of a prepayment, the Company would be required to pay an amount equal to par plus accrued interest plus a make-whole premium. The Purchase Agreement contains certain covenants that restrict the Company’s ability to, among other things, transfer or sell assets, create liens and engage in certain mergers or consolidations. In addition, the Company must comply with a leverage ratio and interest coverage ratio as set forth in the Purchase Agreement. The Purchase Agreement provides for customary events of default. In the case of an event of default arising from specified events of bankruptcy or insolvency, all outstanding 2.58% Senior Euro Notes will become due and payable immediately without further action or notice. In the case of payment events of defaults, any holder of the 2.58% Senior Euro Notes affected thereby may declare all the 2.58% Senior Euro Notes held by it due and payable immediately. In the case of any other event of default, a majority of the holders of the 2.58% Senior Euro Notes may declare all the 2.58% Senior Euro Notes to be due and payable immediately.

On December 6, 2010, the Company completed a public offering of $300.0 million 4.5% senior notes due December 15, 2020 (“4.5% Senior Notes”). The net proceeds from the offering of $295.7 million, after deducting the $1.6 million issuance discount, the $1.9 million underwriting commission and $0.8 million offering expenses, were used to repay $250.0 million of outstanding bank indebtedness, with the balance used for general corporate purposes. The 4.5% Senior Notes bear interest at a rate of 4.5% per annum, which is payable semi-annually in arrears on each June 15^th and December 15^th. The Company may redeem all or a portion of the 4.5% Senior Notes at any time prior to maturity at the redemption prices set forth in the Note Indenture governing the 4.5% Senior Notes. The Company may issue additional debt from time to time pursuant to the Indenture. The Indenture and 4.5% Senior Notes contain covenants that limit the Company’s ability to, among other things, incur certain liens securing indebtedness, engage in certain sale-leaseback transactions, and enter into certain consolidations, mergers, conveyances, transfers or leases of all or substantially all the Company’s assets. The terms of the 4.5% Senior Notes also require the Company to make an offer to repurchase the 4.5% Senior Notes upon a change of control triggering event (as defined in the Indenture) at a price equal to 101% of their principal amount plus accrued and unpaid interest, if any.

On December 9, 2011, the Company completed a public offering of $350.0 million 4.2% senior notes due December 15, 2021 (“4.2% Senior Notes”). The net proceeds from the offering of $346.2 million, after deducting the $0.9 million issuance discount, the $2.3 million underwriting commission and $0.6 million offering expenses, were used to repay $306.0 million of outstanding bank indebtedness, with the balance used for general corporate purposes. The 4.2% Senior Notes bear interest at a rate of 4.2% per annum, which is payable semi-annually in arrears on each June 15^th and December 15^th. The Company may redeem all or a portion of the 4.2% Senior Notes at any time prior to maturity at the redemption prices set forth in the Note Indenture governing the 4.2% Senior Notes. The Company may issue additional debt from time to time pursuant to the Indenture. The Indenture and 4.2% Senior Notes contain covenants that limit the Company’s ability to, among other things, incur certain liens securing indebtedness, engage in certain sale-leaseback transactions, and enter into certain consolidations, mergers, conveyances, transfers or leases of all or substantially all the Company’s assets. The terms of the 4.2% Senior Notes also require the Company to make an offer to repurchase the 4.2% Senior Notes

26

upon a change of control triggering event (as defined in the Indenture) at a price equal to 101% of their principal amount plus accrued and unpaid interest, if any.

On April 15, 2010, the Company entered into a forward starting interest rate contract with a notional amount of $300.0 million with a settlement date in December 2010. This contract was entered into in anticipation of the issuance of the 4.5% Senior Notes and was designed to lock in the market interest rate as of April 15, 2010. In December 2010, the Company settled and paid this interest rate contract for $31.0 million. The $31.0 million is being amortized into interest expense over the 10 year term of the 4.5% Senior Notes, which results in an effective interest rate of 5.8%.

On July 12, 2011, the Company entered into a forward starting interest rate contract with a notional amount of $350.0 million and a settlement date of September 30, 2011. This contract was entered into in anticipation of the issuance of the 4.2% Senior Notes and was designed to lock in the market interest rate as of July 12, 2011. On September 29, 2011, the Company settled this interest rate contract for $34.7 million with a payment made on October 3, 2011. Simultaneously, the Company entered into a separate interest rate contract with a notional amount of $350.0 million and a settlement date of February 28, 2012. The contract was entered into in anticipation of the expected issuance of the 4.2% Senior Notes and was designed to maintain the market rate as of July 12, 2011. In December 2011, the Company settled and paid the September interest rate contract for $4.0 million, resulting in a total settlement of $38.7 million. Of the $38.7 million, $0.8 was recognized as other expense in 2011 and the balance of $37.9 million is being amortized into interest expense over the 10 year term of the 4.2% Senior Notes, which results in an effective interest rate of 5.3%.

There are two key financial covenants that the Company is required to maintain in connection with the Revolving Facility and 2.58% Senior Euro Notes. The most restrictive financial covenants under these debt instruments require a minimum interest coverage ratio of 3.0 to 1 and a maximum leverage ratio of 3.25 to 1. At March 31, 2012, the Company was in compliance with both of these financial covenants, as the Company’s interest coverage ratio was 11.8 to 1 and the leverage ratio was 2.0 to 1. There are no financial covenants relating to the 4.5% Senior Notes or 4.2% Senior Notes.

On December 6, 2011, the Company announced that its Board of Directors increased the authorized level for repurchases of its common stock by approximately $50.0 million. The increased authorization will be added to the approximately $75.0 million that remains available from the existing authorization approved by the Board of Directors on April 21, 2008, resulting in a total authorized repurchase amount of $125.0 million. As of March 31, 2012, 0.2 million shares have been purchased at a cost of $10.2 million.

The Company believes current cash and cash that will be generated from operations will be sufficient to meet its operating cash requirements, planned capital expenditures, interest on all borrowings, pension and postretirement funding requirements, authorized share repurchases and annual dividend payments to holders of the Company’s stock for the remainder of 2012 and 2013. Additionally, in the event that suitable businesses are available for acquisition upon acceptable terms, the Company may obtain all or a portion of the financing for these acquisitions through the incurrence of additional borrowings. As of March 31, 2012, $11.2 million is outstanding under the Revolving Facility.

Item 3.    Quantitative and Qualitative Disclosures About Market Risk.

The Company is subject to market risk associated with changes in foreign currency exchange rates and interest rates. The Company may, from time to time, enter into foreign currency forward contracts and interest rate swaps on its debt when it believes there is a financial advantage in doing so. A treasury risk management policy, adopted by the Board of Directors, describes the procedures and controls over derivative financial and commodity instruments, including foreign currency forward contracts and interest rate swaps. Under the policy, the Company does not use derivative financial or commodity instruments for trading purposes, and the use of these instruments is subject to strict approvals by senior officers. Typically, the use of derivative instruments is limited to foreign currency forward contracts and interest rate swaps on the Company’s outstanding long-term debt.

27

The Company’s foreign currency exchange rate risk is limited principally to the Euro, British Pound, Canadian Dollar and Chinese Renminbi. The Company manages its foreign exchange risk principally through invoicing customers in the same currency as the source of products. The effect of transaction gains and losses is reported within other income (expense)-net on the Consolidated Statements of Operations.

The Company’s interest rate exposure is primarily related to the $773.6 million of total debt outstanding at March 31, 2012. Approximately 2% of the debt is priced at interest rates that float with the market. A 50 basis point movement in the interest rate on the floating rate debt would result in an approximate $0.1 million annualized increase or decrease in interest expense and cash flows. The remaining debt is fixed rate debt.

Item 4.    Controls and Procedures.

The Company maintains disclosure controls and procedures that are designed to ensure that information required to be disclosed in the Company’s Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information 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.

As required by Rule 13a-15(b) promulgated under the Securities Exchange Act, the Company carried out an evaluation, under the supervision and with the participation of the Company’s management, including the Company’s Chief Executive Officer and the Company’s Chief Financial Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures as of the end of the period covered by this report. Based on the foregoing, the Company’s Chief Executive Officer and Chief Financial Officer concluded as of March 31, 2012, that the Company’s disclosure controls and procedures were effective.

There has been no change in the Company’s internal controls over financial reporting during the Company’s most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, the Company’s internal controls over financial reporting.

PART II. OTHER INFORMATION

Item 1.    Legal Proceedings.

The Company and seven of its subsidiaries are presently named as defendants in a number of lawsuits claiming various asbestos-related personal injuries, allegedly as a result of exposure to products manufactured with components that contained asbestos. Such components were acquired from third party suppliers, and were not manufactured by any of the subsidiaries. To date, the majority of the Company’s settlements and legal costs, except for costs of coordination, administration, insurance investigation and a portion of defense costs, have been covered in full by insurance, subject to applicable deductibles. However, the Company cannot predict whether and to what extent insurance will be available to continue to cover such settlements and legal costs, or how insurers may respond to claims that are tendered to them. Claims have been filed in jurisdictions throughout the United States. Most of the claims resolved to date have been dismissed without payment. The balance have been settled for various insignificant amounts. Only one case has been tried, resulting in a verdict for the Company’s business unit. No provision has been made in the financial statements of the Company, other than for insurance deductibles in the ordinary course, and the Company does not currently believe the asbestos-related claims will have a material adverse effect on the Company’s business, financial position, results of operations or cash flow.

The Company is also party to various other legal proceedings arising in the ordinary course of business, none of which is expected to have a material adverse effect on its business, financial condition, results of operations or cash flow.

Item 2.    Unregistered Sales of Equity Securities and Use of Proceeds.

The following table provides information about Company purchases of its common stock during the quarter ended March 31, 2012:

Period	Total Number of Shares Purchased		Average Price Paid per  Share		Total Number of Shares Purchased as Part of Publicly Announced Plans or Programs(1)	Maximum Dollar Value that  May Yet be Purchased Under the Plans or Programs(1)

(1) On December 6, 2011, the Company announced that its Board of Directors had increased the authorized level for repurchases of its common stock by approximately $50.0 million. The increased authorization was added to the approximately $75.0 million that remains available from the existing authorization approved by the Board of Directors on April 21, 2008, resulting in a total authorized repurchase amount of $125.0 million.

PERSONAL AND CONFIDENTIAL VIA EMAIL

July 18,2005

Mr. Heath A. Mitts

Dear Heath:

We are pleased to confirm our offer to you for the position of Vice President, Corporate Finance for IDEX Corporation. The position will be based at the corporate headquarters in Northbrook, Illinois. In this position, you will report directly to Dominic Romeo, Vice President and Chief Financial Officer.

The following terms apply:

• Your annual base salary will be $225,000, payable on a biweekly basis at the rate of $8,653.85 per pay period. You will be eligible for a review of your salary with consideration for an increase on January 1, 2006. While we hope that you have a long and mutually beneficial relationship with IDEX, your employment will not be for any fixed term or definite period and may be terminated at any time.

• You will be eligible for participation in our Management Incentive Compensation Plan (MICP), which provides an annual incentive earnings opportunity based on company and personal performance. You will be placed in Salary Range 22 with a target level of incentive compensation of 50% of your annual base pay in effect at the beginning of the plan year. The actual payout under the plan could be from 0% to 130% of base salary depending upon the performance of IDEX and your individual performance.

• You will be eligible for the full range of ChoiceComp benefits for IDEX employees at the Northbrook headquarters, including the IDEX Defined Contribution Retirement Plan, IDEX Corporation Supplemental Executive Retirement Plan (benefits in excess of the IRS limits), 401 (k) IDEX Savings Plan, medical and dental coverage, short-term and long-term disability coverage, life insurance, and enhanced one million-dollar business travel accident coverage. A ChoiceComp folder describing our flexible benefit plan is enclosed. You will be eligible for medical coverage on the first of the month following your employment date.

• Subject to approval of our Board of Directors, we expect to award you annual equity grants under the IDEX Incentive Award Plan. This plan is designed to provide an incentive and reward to key employees who are in a position to make substantial contributions to the success of the company. A combination of stock options and restricted stock is normally awarded to Officers at the Annual Shareholders’ Meeting in March. For the March 2006 grant, you shall receive the equivalent of a minimum of 12,000 stock options, which approximates $150,000 in expected value, with a portion delivered in restricted stock at a conversion rate of approximately 3 to 1.

Letter to Mr. Heath A. Mitts

July 18,2005 Page Two

• Effective January 1, 2006, you will be eligible to participate in the IDEX Deferred Compensation Plan for Officers, which provides an alternative to defer income and subsequent earnings on that income until after retirement.

• As an IDEX officer, you are eligible to use a company-provided car under the IDEX Car Policy with a target value of $34,000 including tax, title, and license. You will be subject to taxable income for the personal use of this car under current IRS regulations. We will assist you to place the order through Wheels, Inc., which supplies our company cars.

• You will be eligible for three (3) weeks of vacation annually. Additionally, the IDEX Holiday schedule typically contains 14 paid holidays, including a shutdown period during the December holiday season.

• You will be eligible for the complete provisions of the IDEX moving policy, as it applies to current employees, including temporary living, closing costs for the purchase of a Chicago-area home, and payment of moving expenses not otherwise reimbursed by PerkinElmer upon your repatriation from Singapore. A copy of the moving policy is attached.

In addition, you will be provided tax preparation services relating to your foreign assignment and repatriation, for 2005 and 2006, should PerkinElmer not provide this support.

• As a special sign-on incentive to offset your unvested stock options at PerkinElmer, an initial equity grant will be awarded to you on your start date in the amount of 3,500 shares of restricted stock and 20,000 stock options. The initial price at which the options are granted will be the fair market value on the day immediately prior to the effective date of the grant. Option vesting will occur ratably over four years; restricted shares will cliff vest on the fourth anniversary of the grant.

• As a replacement for your forfeited 2005 PerkinElmer annual bonus, we have agreed to pay you up to $57,000. In addition, for 2005, we will guarantee that the combination of this replacement bonus and your prorata 2005 MICP award from IDEX will be no less than $100,000. This payment will be made during February 2006 at the time of normal MICP award payouts, subject to confirmation that you forfeited your entire 2005 PerkinElmer award.

• As discussed with you, we expect that IDEX will continue to grow and prosper as an independent publicly-owned company. However, in the event of a “Change in Control,” as defined in the 2005 Incentive Award Plan, that results in your termination from service within 24 months of the Change in Control, the Company would be obligated to pay your salary at the rate then in effect and your then current target MICP bonus for a minimum of 24 months following the date of termination. This payment would not be applicable in the event of your resignation.

Dear Heath:

As part of our ongoing review of our executive compensation programs, IDEX Corporation seeks to ensure that executives are provided market competitive protection benefits.

Based upon the results of that review, and while we fully expect that IDEX will continue to grow and prosper as an independent publicly-traded company, we are offering the following levels of benefit based upon your role as Vice President, Corporate Finance for IDEX Corporation in the case of unforeseen circumstances.

Such benefit will not be applicable in the event of your voluntary termination.

• All other provisions of your current IDEX compensation and benefits programs remain the same.

Please indicate your acceptance of these provisions below.

Heath, we appreciate your contributions to IDEX and wish you continuing success.

Sincerely

Income Taxes [Abstract]

Income Taxes

17.    Income Taxes

The Company's provision for income taxes is based upon estimated annual tax rates for the year applied to federal, state and foreign income. The provision for income taxes decreased to $21.9 million in the first quarter of 2012 from $22.4 million in the first quarter of 2011. The effective tax rate decreased to 29.5% for the first quarter of 2012 compared to 31.8% in the first quarter of 2011 due to the mix of global pre-tax income among jurisdictions, a decrease in the amount of disallowed executive compensation expense and as a result of recent acquisitions.

The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction, and various state and foreign jurisdictions. Due to the potential for resolution of federal, state and foreign examinations, and the expiration of various statutes of limitation, it is reasonably possible that the Company's gross unrecognized tax benefits balance may change within the next twelve months by a range of zero to $1.6 million.

Basis Of Presentation And Significant Accounting Policies [Abstract]

Basis Of Presentation And Significant Accounting Policies

1.    Basis of Presentation and Significant Accounting Policies

The Condensed Consolidated Financial Statements of IDEX Corporation ("IDEX" or the "Company") have been prepared in accordance with the instructions to Form 10-Q under the Securities Exchange Act of 1934, as amended. The statements are unaudited but include all adjustments, consisting only of recurring items, except as noted, that the Company considers necessary for a fair presentation of the information set forth herein. The results of operations for the three months ended March 31, 2012 are not necessarily indicative of the results to be expected for the entire year.

The condensed consolidated financial statements and Management's Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2011.

Adoption of New Accounting Standards

In May 2011, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2011-04 which was issued to provide a consistent definition of fair value and ensure that the fair value measurement and disclosure requirements are similar between U.S. Generally Accepted Accounting Principles ("GAAP") and International Financial Reporting Standards ("IFRS"). ASU 2011-04 changes certain fair value measurement principles and enhances the disclosure requirements particularly for Level 3 fair value measurements. The Company adopted this guidance on January 1, 2012, and its adoption did not impact the consolidated financial position, results of operations or cash flows of the Company.

In June 2011, FASB issued ASU 2011-05 "Presentation of Comprehensive Income" ("ASU 2011-05"). ASU 2011-05 allows an entity to present components of net income and other comprehensive income in one continuous statement, referred to as the statement of comprehensive income, or in two separate, but consecutive statements. The new guidance eliminates the current option to report other comprehensive income and its components in the statement of changes in equity. While ASU 2011-05 changes the presentation of comprehensive income, there are no changes to the components that are recognized in net income or other comprehensive income under current accounting guidance. In December 2011, FASB issued ASU 2011-12 "Comprehensive Income (Topic 220); Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05" ("ASU 2011-12"). ASU 2011-12 deferred certain aspects of ASU 2011-05. The new guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. The adoption of ASU 2011-05 and the deferrals in ASU 2011-12 did not impact the consolidated financial position, results of operations or cash flows of the Company.

Share-Based Compensation [Abstract]

Share-Based Compensation

14.    Share-Based Compensation

During the three months ended for both March 31, 2012 and 2011, the Company granted approximately 0.7 million stock options and 0.2 million unvested shares, respectively.

Weighted average option fair values and assumptions for the periods specified are disclosed in the following table:

	Three Months Ended March 31,
	2012	2011
Weighted average fair value of option grants	$11.47	$12.34
Dividend yield	1.57%	1.46%
Volatility	32.01%	32.76%
Risk-free forward interest rate	0.17% - 3.98%	0.28% - 5.62%
Expected life (in years)	5.98	6.18

The assumptions are as follows:

• The Company estimated volatility using its historical share price performance over the contractual term of the option.

• The Company uses historical data to estimate the expected life of the option. The expected life assumption for the three months ended March 31, 2012 and 2011 is an output of the Binomial lattice option-pricing model, which incorporates vesting provisions, rate of voluntary exercise and rate of post-vesting termination over the contractual life of the option to define expected employee behavior.

• The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for periods within the contractual life of the option. For the three months ended March 31, 2012 and 2011, we present the range of risk-free one-year forward rates, derived from the U.S. treasury yield curve, utilized in the Binomial lattice option-pricing model.

• The expected dividend yield is based on the Company's current dividend yield as the best estimate of projected dividend yield for periods within the contractual life of the option.

The Company's policy is to recognize compensation cost on a straight-line basis over the requisite service period for the entire award. Additionally, the Company's general policy is to issue authorized and unissued shares of common stock to satisfy stock option exercises or grants of unvested shares.

Total compensation cost for the stock options is as follows:

	Three Months Ended March 31,
	2012			2011
	(In thousands)
Cost of goods sold	$	293		$	235
Selling, general and administrative expenses		1,966			2,053
Total expense before income taxes		2,259			2,288
Income tax benefit		(708	)		(736	)
Total expense after income taxes	$	1,551		$	1,552

Total compensation cost for the unvested shares is as follows:

	Three Months Ended March 31,
	2012			2011
	(In thousands)
Cost of goods sold	$	406		$	148
Selling, general and administrative expenses		1,996			2,413
Total expense before income taxes		2,402			2,561
Income tax benefit		(663	)		(504	)
Total expense after income taxes	$	1,739		$	2,057

Classification of stock compensation cost within the Consolidated Statements of Operations is consistent with classification of cash compensation for the same employees and $0.5 million of compensation cost was capitalized as part of inventory as of March 31, 2012, while $0.2 million was capitalized as of December 31, 2011.

As of March 31, 2012, there was $12.6 million of total unrecognized compensation cost related to stock options that is expected to be recognized over a weighted-average period of 1.6 years, and $14.0 million of total unrecognized compensation cost related to unvested shares that is expected to be recognized over a weighted-average period of 1.3 years.

Less current portion		3,796		2,444
Total long-term borrowings	$	769,850	$	806,366

On June 27, 2011, the Company entered into a credit agreement (the "Credit Agreement") along with certain of its subsidiaries, as borrowers (the "Borrowers"), with Bank of America, N.A., as administrative agent, swing line lender and an issuer of letters of credit, and other lenders party thereto. The Credit Agreement replaced the Company's previous $600.0 million credit facility, which was due to expire in December 2011.

The Credit Agreement consists of a revolving Credit Facility in an aggregate principal amount of $700.0 million with a maturity date of June 27, 2016. The maturity date may be extended under certain conditions for an additional one-year term prior to the second anniversary of the initial closing date of June 27, 2011. Up to $75.0 million of the Revolving Facility is available for the issuance of letters of credit. Additionally, up to $25.0 million of the Revolving Facility is available to the Company for swing line loans, available on a same-day basis.

Proceeds of the Revolving Facility are available for use by the Borrowers for working capital and other general corporate purposes, including refinancing existing debt of the Company and its subsidiaries. The Company may request increases in the lending commitments under the Credit Agreement, but the aggregate lending commitments may not exceed $950.0 million. The Company has the right, subject to certain conditions set forth in the Credit Agreement, to designate certain foreign subsidiaries of the Company as borrowers under the Credit Agreement. In connection with any such designation, the Company is required to guarantee the obligations of any such subsidiaries under the Credit Agreement. Under the Credit Agreement, Fluid Management Europe B.V., ("FME") and IDEX UK Ltd. ("IDEX UK") were approved by the lenders as designated borrowers. At March 31, 2012, FME had no borrowings under the Revolving Facility, while IDEX UK's borrowings under the Revolving Facility were £2.0 million ($3.2 million). As IDEX UK's borrowings under the Revolving Facility are British Pound denominated and the cash flows that will be used to make payments of principal and interest are predominately generated in British Pounds, the Company does not anticipate any significant foreign exchange gains or losses in servicing this debt.

Borrowings under the Revolving Facility bear interest, at either an alternate base rate or an adjusted LIBOR rate plus, an applicable margin. Such applicable margin is based on the Company's senior, unsecured, long-term debt rating and can range from .875% to 1.70%. Based on the Company's credit rating at March 31, 2012, the applicable margin was 1.05%. Interest is payable (a) in the case of base rate loans, quarterly, and (b) in the case of LIBOR rate loans, on the maturity date of the borrowing, or quarterly from the effective date for borrowings exceeding three months. An annual Revolving Facility fee, also based on the Company's credit rating, is currently 20 basis points and is payable quarterly.

The Credit Agreement contains affirmative and negative covenants that the Company believes are usual and customary for senior unsecured credit agreements, including a financial covenant requiring the maintenance of a 3.25 to 1.0 or lower leverage ratio, which is the ratio of the Company's consolidated total debt to its consolidated EBITDA, each as defined in the Credit Agreement.

The Credit Agreement also contains customary events of default (subject to grace periods, as appropriate) including among others: nonpayment of principal, interest or fees; breach of the representations or warranties in any material respect; breach of the financial, affirmative or negative covenants; payment default on, or acceleration of, other material indebtedness; bankruptcy or insolvency; material judgments entered against the Company or any of its subsidiaries; certain specified events under the Employee Retirement Income Security Act of 1974, as amended; certain changes in control of the Company; and the invalidity or unenforceability of the Credit Agreement or other documents associated with the Credit Agreement.

At March 31, 2012, there was $11.2 million outstanding under the Revolving Facility with $7.0 million of outstanding letters of credit. The net available borrowing capacity under the Revolving Facility at March 31, 2012, was approximately $681.8 million.

On June 9, 2010, the Company completed a private placement of €81.0 million ($96.8 million) aggregate principal amount of 2.58% Series 2010 Senior Euro Notes due June 9, 2015 ("2.58% Senior Euro Notes") pursuant to a Master Note Purchase Agreement, dated June 9, 2010 (the "Purchase Agreement"). The Purchase Agreement provides for the issuance of additional series of notes in the future, provided that the aggregate principal amount outstanding under the agreement at any time does not exceed $750.0 million. The 2.58% Senior Euro Notes bear interest at a rate of 2.58% per annum, which is payable semi-annually in arrears on each June 9^th and December 9^th and will mature on June 9, 2015. The 2.58% Senior Euro Notes are unsecured obligations of the Company and rank pari passu in right of payment with all of the Company's other senior debt. The Company may at any time prepay all or any portion of the 2.58% Senior Euro Notes; provided that any such portion is greater than 5% of the aggregate principal amount of Notes then outstanding under the Purchase Agreement. In the event of a prepayment, the Company would be required to pay an amount equal to par plus accrued interest plus a make-whole premium. The Purchase Agreement contains certain covenants that restrict the Company's ability to, among other things, transfer or sell assets, create liens and engage in certain mergers or consolidations. In addition, the Company must comply with a leverage ratio and interest coverage ratio as set forth in the Purchase Agreement. The Purchase Agreement provides for customary events of default. In the case of an event of default arising from specified events of bankruptcy or insolvency, all outstanding 2.58% Senior Euro Notes will become due and payable immediately without further action or notice. In the case of payment events of defaults, any holder of the 2.58% Senior Euro Notes affected thereby may declare all the 2.58% Senior Euro Notes held by it due and payable immediately. In the case of any other event of default, a majority of the holders of the 2.58% Senior Euro Notes may declare all the 2.58% Senior Euro Notes to be due and payable immediately.

On December 6, 2010, the Company completed a public offering of $300.0 million 4.5% senior notes due December 15, 2020 ("4.5% Senior Notes"). The net proceeds from the offering of $295.7 million, after deducting the $1.6 million issuance discount, the $1.9 million underwriting commission and $0.8 million offering expenses, were used to repay $250.0 million of outstanding bank indebtedness, with the balance used for general corporate purposes. The 4.5% Senior Notes bear interest at a rate of 4.5% per annum, which is payable semi-annually in arrears on each June 15^th and December 15^th. The Company may redeem all or a portion of the 4.5% Senior Notes at any time prior to maturity at the redemption prices set forth in the Note Indenture governing the 4.5% Senior Notes. The Company may issue additional debt from time to time pursuant to the Indenture. The Indenture and 4.5% Senior Notes contain covenants that limit the Company's ability to, among other things, incur certain liens securing indebtedness, engage in certain sale-leaseback transactions, and enter into certain consolidations, mergers, conveyances, transfers or leases of all or substantially all the Company's assets. The terms of the 4.5% Senior Notes also require the Company to make an offer to repurchase the 4.5% Senior Notes upon a change of control triggering event (as defined in the Indenture) at a price equal to 101% of their principal amount plus accrued and unpaid interest, if any.

On December 9, 2011, the Company completed a public offering of $350.0 million 4.2% senior notes due December 15, 2021 ("4.2% Senior Notes"). The net proceeds from the offering of $346.2 million, after deducting the $0.9 million issuance discount, the $2.3 million underwriting commission and $0.6 million offering expenses, were used to repay $306.0 million of outstanding bank indebtedness, with the balance used for general corporate purposes. The 4.2% Senior Notes bear interest at a rate of 4.2% per annum, which is payable semi-annually in arrears on each June 15^th and December 15^th. The Company may redeem all or a portion of the 4.2% Senior Notes at any time prior to maturity at the redemption prices set forth in the Note Indenture governing the 4.2% Senior Notes. The Company may issue additional debt from time to time pursuant to the Indenture. The Indenture and 4.2% Senior Notes contain covenants that limit the Company's ability to, among other things, incur certain liens securing indebtedness, engage in certain sale-leaseback transactions, and enter into certain consolidations, mergers, conveyances, transfers or leases of all or substantially all the Company's assets. The terms of the 4.2% Senior Notes also require the Company to make an offer to repurchase the 4.2% Senior Notes upon a change of control triggering event (as defined in the Indenture) at a price equal to 101% of their principal amount plus accrued and unpaid interest, if any.

Other borrowings of $7.0 million at March 31, 2012 were comprised of capital leases as well as debt at international locations maintained for working capital purposes. Interest is payable on the outstanding debt balances at the international locations at rates ranging from 1.5% to 5.2% per annum.

There are two key financial covenants that the Company is required to maintain in connection with the Revolving Facility and 2.58% Senior Euro Notes. The most restrictive financial covenants under these debt instruments require a minimum interest coverage ratio of 3.0 to 1 and a maximum leverage ratio of 3.25 to 1. At March 31, 2012, the Company was in compliance with both of these financial covenants. There are no financial covenants relating to the 4.5% Senior Notes or 4.2% Senior Notes.

Derivative Instruments [Abstract]

Derivative Instruments

11.    Derivative Instruments

The Company enters into cash flow hedges to reduce the exposure to variability in certain expected future cash flows. The type of cash flow hedges the Company enters into includes foreign currency contracts and interest rate exchange agreements that effectively convert a portion of floating-rate debt to fixed-rate debt and are designed to reduce the impact of interest rate changes on future interest expense.

The effective portion of gains or losses on interest rate exchange agreements is reported in accumulated other comprehensive income (loss) in shareholders' equity and reclassified into net income in the same period or periods in which the hedged transaction affects net income. The remaining gain or loss in excess of the cumulative change in the present value of future cash flows or the hedged item, if any, is recognized into net income during the period of change.

Fair values relating to derivative financial instruments reflect the estimated amounts that the Company would receive or pay to sell or buy the contracts based on quoted market prices of comparable contracts at each balance sheet date.

On April 15, 2010, the Company entered into a forward starting interest rate contract with a notional amount of $300.0 million with a settlement date in December 2010. This contract was entered into in anticipation of the issuance of the 4.5% Senior Notes and was designed to lock in the market interest rate as of April 15, 2010. In December 2010, the Company settled and paid this interest rate contract for $31.0 million. The $31.0 million is being amortized into interest expense over the 10 year term of the 4.5% Senior Notes, which results in an effective interest rate of 5.8%.

On July 12, 2011, the Company entered into a forward starting interest rate contract with a notional amount of $350.0 million and a settlement date of September 30, 2011. This contract was entered into in anticipation of the issuance of the 4.2% Senior Notes and was designed to lock in the market interest rate as of July 12, 2011. On September 29, 2011, the Company settled this interest rate contract for $34.7 million with a payment made on October 3, 2011. Simultaneously, the Company entered into a separate interest rate contract with a notional amount of $350.0 million and a settlement date of February 28, 2012. The contract was entered into in anticipation of the expected issuance of the 4.2% Senior Notes and was designed to maintain the market rate as of July 12, 2011. In December 2011, the Company settled and paid the September interest rate contract for $4.0 million, resulting in a total settlement of $38.7 million. Of the $38.7 million, $0.8 was recognized as other expense in 2011 and the balance of $37.9 million is being amortized into interest expense over the 10 year term of the 4.2% Senior Notes, which results in an effective interest rate of 5.3%.

As of March 31, 2012, the Company did not have any interest rate contracts outstanding.

The following table summarizes the gain (loss) recognized and the amounts and location of income (expense) and gain (loss) reclassified into income for interest rate contracts and foreign currency contracts for March 31, 2012 and 2011:

	Gain (Loss) Recognized  in Other Comprehensive Income					(Expense) and Gain Reclassified into Income

Approximately $7.6 million of the pre-tax amount included in accumulated other comprehensive income (loss) in shareholders' equity at March 31, 2012 will be recognized to net income over the next 12 months as the underlying hedged transactions are realized.

(1) Revised to reflect the movement of the Dispensing Equipment segment to the Fire & Safety/Diversified Products segment and the transfer of $20.6 million of goodwill related to the movement of our Trebor business unit within the Health & Science Technologies segment to the Fluid & Metering Technologies segment.

ASC 350 "Goodwill and Other Intangible Assets" requires that goodwill be tested for impairment at the reporting unit level on an annual basis and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of the reporting unit below its carrying value. Annually on October 31, goodwill and other acquired intangible assets with indefinite lives are tested for impairment. The Company concluded that the fair value of each of the reporting units was in excess of the carrying value as of October 31, 2011. The Company did not consider there to be any triggering event that would require an interim impairment assessment, therefore none of the goodwill or other acquired intangible assets with indefinite lives were tested for impairment during the three months ended March 31, 2012.

The following table provides the gross carrying value and accumulated amortization for each major class of intangible asset at March 31, 2012 and December 31, 2011:

Earnings Per Common Share

Earnings Per Common Share [Abstract]

Earnings Per Common Share

5. Earnings Per Common Share

Earnings per common share ("EPS") are computed by dividing net income by the weighted average number of shares of common stock (basic) plus common stock equivalents outstanding (diluted) during the period. Common stock equivalents consist of stock options, which have been included in the calculation of weighted average shares outstanding using the treasury stock method, unvested shares, and shares issuable in connection with certain deferred compensation agreements ("DCUs").

ASC 260 "Earnings Per Share", concludes that all outstanding unvested share-based payment awards that contain rights to nonforfeitable dividends participate in undistributed earnings with common shareholders. If awards are considered participating securities, the Company is required to apply the two-class method of computing basic and diluted earnings per share. The Company has determined that its outstanding unvested shares are participating securities. Accordingly, earnings per common share are computed using the two-class method prescribed by ASC 260. Net income attributable to common shareholders was reduced by $0.2 million and $0.4 million for the three months ended March 31, 2012 and 2011, respectively.

Basic weighted average shares reconciles to diluted weighted average shares as follows:

	Three Months Ended March 31,
	2012		2011
	(In thousands)
Basic weighted average common shares outstanding		82,804		81,430
Dilutive effect of stock options, unvested shares, and DCUs		1,098		1,818
Diluted weighted average common shares outstanding		83,902		83,248

Options to purchase approximately 1.3 million and 0.7 million shares of common stock for the three months ended March 31, 2012 and 2011, respectively, were not included in the computation of diluted EPS because the exercise price was greater than the average market price of the Company's common stock and, therefore, the effect of their inclusion would be antidilutive.

2.    Restructuring

During 2011, the Company began recording restructuring costs as a result of initiatives that support the implementation of key strategic efforts designed to facilitate long-term sustainable growth through cost reduction actions, primarily consisting of employee reductions and facility rationalization. The costs incurred related to these initiatives are included in Restructuring expenses in the Consolidated Statements of Operations while the restructuring accruals are included in Accrued expenses in our Consolidated Balance Sheets.

During the three months ended March 31, 2012, the Company recorded $4.9 million of pre-tax restructuring expenses related to its 2011 restructuring initiative for employee severance related to employee reductions across various functional areas as well as facility rationalization. The 2011 restructuring initiatives included severance benefits for 337 employees.

Pre-tax restructuring expenses, by segment, for 2012, were as follows:

	Severance Costs		Exit Costs		Total

Fair Value Measurements [Abstract]

Fair Value Measurements

12.    Fair Value Measurements

ASC 820 "Fair Value Measurements and Disclosures" defines fair value, provides guidance for measuring fair value and requires certain disclosures. This standard discusses valuation techniques, such as the market approach (comparable market prices), the income approach (present value of future income or cash flow), and the cost approach (cost to replace the service capacity of an asset or replacement cost). The standard utilizes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The following is a brief description of those three levels:

• Level 1: Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities.

• Level 2: Inputs, other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active.

• Level 3: Unobservable inputs that reflect the reporting entity's own assumptions.

The following table summarizes the basis used to measure the Company's financial assets and (liabilities) at fair value on a recurring basis in the balance sheet at March 31, 2012 and December 31, 2011:

	Basis of Fair Value Measurements
	Balance at March 31,  2012			Level 1		Level 2		Level 3
	(In thousands)
Money market investment	$	15,402		$	15,402	$	—	$	—
Available for sale securities		3,326			3,326		—		—
Contingent consideration		(1,500	)		—		—		(1,500	)

	Basis of Fair Value Measurements
	Balance at December 31, 2011			Level 1		Level 2		Level 3
	(In thousands)
Money market investment	$	11,899		$	11,899	$	—	$	—
Available for sale securities		2,785			2,785		—		—
Contingent consideration		(3,000	)		—		—		(3,000	)

There were no transfers of assets or liabilities between Level 1 and Level 2 during the first three months of 2012 or 2011.

In determining the fair value of the Company's contingent consideration upon acquisition of AT Films, the Company used a probability weighted estimate adjusted for the time value of money. In February 2012, the Company paid $1.5 million on the contingent consideration arrangement. The maximum remaining liability is $1.5 million, which is reflected in Accrued expenses and is expected to be paid in the first quarter of 2013.

The carrying value of our cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximates their fair values because of the short term nature of these instruments. At March 31, 2012, the fair value of our Revolving Facility, 2.58% Senior Euro Notes, 4.5% Senior Notes and 4.2% Senior Notes, based on quoted market prices and current market rates for debt with similar credit risk and maturity, was approximately $785.5 million compared to the carrying value of $766.7 million. This fair value measurement is classified as Level 2 within the fair value hierarchy since it is determined based upon significant inputs observable in the market, including interest rates on recent financing transactions to entities with a credit rating similar to ours.
