NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

The condensed consolidated balance sheet as of March 31, 2011, the condensed consolidated statements of operations for the three months ended March 31, 2011 and 2010 and the condensed consolidated statements of cash flows for the three months ended March 31, 2011 and 2010 have been prepared by Ampco-Pittsburgh Corporation (the Corporation) without audit. In the opinion of management, all adjustments, consisting of only normal and recurring adjustments necessary to present fairly the financial position, results of operations and cash flows for the periods presented, have been made. The results of operations for the three months ended March 31, 2011 are not necessarily indicative of the operating results expected for the full year.

Certain information and footnote disclosures normally included in the annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted.

Recently Implemented Accounting Pronouncements

In September 2009, the Financial Accounting Standards Board (FASB) issued ASU 2009-13, Multiple-Deliverable Revenue Arrangements, which addresses the accounting and revenue recognition of sales contracts with multiple products and/or services when such products and/or services are provided to the customer at different points in time or over different time periods. ASU 2009-13 requires the sales consideration to be allocated, at the inception of the arrangement, to each deliverable and/or service using the relative selling price method. ASU 2009-13 became effective prospectively for revenue arrangements entered into or materially modified on or after January 1, 2011 and did not have a significant impact on the operating results, financial position or liquidity of the Corporation.

At March 31, 2011 and December 31, 2010, approximately 57% and 60%, respectively, of the inventories were valued on the LIFO method with the remaining inventories valued on the FIFO method. Inventories were comprised of the following:

Contributions for the three months ended March 31, 2011 and 2010 were as follows:

Net periodic pension and other postretirement costs include the following components:

Outstanding standby and commercial letters of credit as of March 31, 2011 approximated $20,131,000, a major portion of which serves as collateral for the Industrial Revenue Bond debt.

In 2010, UES-UK was awarded a governmental grant of up to $1,325,000 (£850,000) toward the purchase and installation of certain machinery and equipment of which $484,000 (£300,000) was received in 2011 and $226,000 (£145,000) in 2010. Under the agreement, the grant is repayable if certain conditions are not met including achieving and maintaining a targeted level of employment through 2017. UES-UK’s level of employment currently exceeds and is expected to continue to exceed the targeted level of employment; accordingly, no liability has been recorded.

The Corporation’s comprehensive income (loss) consisted of:

Certain of the Corporation’s operations are subject to risk from exchange rate fluctuations in connection with sales in foreign currencies. To minimize this risk, foreign currency sales contracts are entered into which are designated as cash flow or fair value hedges and are recorded in the condensed consolidated balance sheet as either an asset or a liability measured at their fair value. The accounting for changes in the fair value of a derivative depends on the use of the derivative. To the extent that a derivative is designated and effective as a cash flow hedge of an exposure to future changes in value, the change in fair value of the derivative is deferred in accumulated other comprehensive income (loss). Any portion considered to be ineffective, including that arising from the unlikelihood of an anticipated transaction to occur, is reported as a component of earnings (other income/expense) immediately. Upon occurrence of the anticipated transaction, the derivative designated and effective as a cash flow hedge is de-designated as a fair value hedge and the change in fair value previously deferred in accumulated other comprehensive income (loss) is reclassified to earnings (net sales) with subsequent changes in fair value recorded as a component of earnings (other income/expense). To the extent that a derivative is designated and effective as a hedge of an exposure to changes in fair value, the change in the derivative’s fair value will be offset in the condensed consolidated statement of operations by the change in the fair value of the item being hedged and is recorded as a component of earnings (other income/expense).

No portion of the existing cash flow or fair value hedges is considered to be ineffective, including any ineffectiveness arising from the unlikelihood of an anticipated transaction to occur. Additionally, no amounts have been excluded from assessing the effectiveness of the hedge.

As of March 31, 2011, approximately $26,351,000 of anticipated foreign-denominated sales has been hedged of which $3,492,000 is covered by cash flow contracts settling at various dates through June 2012 and the remaining $22,859,000 is covered by fair value contracts settling at various dates through September 2013. As of March 31, 2011, the fair value of foreign currency sales contracts designated as cash flow hedges expecting to settle within the next 12 months approximated $108,000 and is recorded as other current assets. The fair value of the remaining cash flow contracts equaled $29,000 and is recorded as other noncurrent assets. The change in the fair value of the contracts is recorded as a component of accumulated other comprehensive income (loss) and approximated $53,000 and $281,000, net of income taxes, as of March 31, 2011 and December 31, 2010, respectively. During the three months ended March 31, 2011, approximately $(112,000), net of income taxes, was recognized as comprehensive income (loss) and $116,000, net of income taxes was released from accumulated other comprehensive income (loss). The change in the fair value will be reclassified to earnings when the projected sales occur with approximately $85,000 expected to be released to pre-tax earnings within the next 12 months. During the three months ended March 31, 2011 and 2010, approximately $183,000 and $51,000, respectively, was released to pre-tax earnings.

As of March 31, 2011, the fair value of foreign currency sales contracts designated as fair value hedges expecting to settle within the next 12 months approximated $105,000 and is recorded as other current assets. (The fair value of the related hedged item, recorded as other current liabilities, approximated $119,000.) The fair value of the remaining fair value hedges equaled $344,000 and is recorded as other noncurrent assets. (The fair value of the related hedged item, recorded as other noncurrent liabilities, approximated $406,000.) The fair value of assets held as collateral as of March 31, 2011 approximated $802,000.

Gains (losses) on foreign exchange transactions included in other income (expense) approximated $(191,000) and $920,000 for the three months ended March 31, 2011 and 2010, respectively.

In May 2009, the Corporation entered into foreign currency purchase contracts to manage the volatility associated with Euro-denominated progress payments to be made for certain machinery and equipment. The change in the fair value of the contracts is recorded as a component of accumulated other comprehensive income (loss) and approximated $323,000 and $329,000, net of income taxes, as of March 31, 2011 and December 31, 2010, respectively. All contracts were settled as of December 31, 2010; accordingly, no amounts were recognized as comprehensive income (loss) during the three months ended March 31, 2011 and $6,000 was released from accumulated other comprehensive income (loss) for the same period. The change in the fair value is being amortized to pre-tax earnings (as an offset to depreciation expense) over the life of the underlying assets. Approximately $8,000 was released to pre-tax earnings for the three months then ended and $32,000 is expected to be released to pre-tax earnings within the next 12 months.

At March 31, 2011, the Corporation has purchase commitments covering 55% or $14,700,000 of anticipated natural gas usage over approximately the next four to five years at one of its subsidiaries. The commitments qualify as normal purchases and, accordingly, are not reflected on the condensed consolidated balance sheet.

Additionally, one of the Corporation’s subsidiaries is subject to risk from increases in the price of commodities (copper and aluminum) used in the production of inventory. To minimize this risk, futures contracts are entered into which are designated as cash flow hedges. The change in fair value of the derivative is deferred in accumulated other comprehensive income (loss). Any portion considered to be ineffective, including that arising from the unlikelihood of an anticipated transaction to occur, is reported as a component of earnings (other income/expense) immediately. Upon occurrence of the anticipated transaction, the futures contract is settled and the change in fair value previously deferred in accumulated other comprehensive income (loss) is reclassified to earnings (costs of products sold) when the projected sales occur. At March 31, 2011, approximately 64% or $3,726,000 of anticipated copper purchases and 63% or $918,000 of anticipated aluminum purchases are hedged over the next six to eight months. The fair value of these contracts (both outstanding and settled) approximated $419,000 as of March 31, 2011. The change in the fair value of the contracts designated as cash flow hedges is recorded as a component of accumulated other comprehensive income (loss) and approximated $261,000 and $589,000, net of income taxes, as of March 31, 2011 and December 31, 2010, respectively. During the three months ended March 31, 2011, approximately $(14,000), net of income taxes, was recognized as comprehensive income (loss) and $314,000, net of income taxes, was released from accumulated other comprehensive income (loss). Additionally, $419,000 of the change in fair value is expected to be released to pre-tax earnings over the next 12 months. During the three months ended March 31, 2011 and 2010, approximately $504,000 and $168,000, respectively, was released to pre-tax earnings. The fair value of assets held as collateral as of March 31, 2011 approximated $463,000.

The Corporation does not enter into derivative transactions for speculative purposes and, therefore, holds no derivative instruments for trading purposes.

Stock-based compensation expense associated for the three months ended March 31, 2011 and 2010 equaled $348,000 and $1,644,000, respectively. The related income tax benefit recognized in the condensed consolidated statement of operations for the related periods was approximately $122,000 and $575,000, respectively.

In May 2011, the Compensation Committee granted 176,250 non-qualified stock options. The options have a ten-year life and vest over a three year period.

Litigation

The Corporation and its subsidiaries are involved in various claims and lawsuits incidental to their businesses. In addition, it is also subject to asbestos litigation as described below.

Asbestos Litigation

Claims have been asserted alleging personal injury from exposure to asbestos-containing components historically used in some products of predecessors of the Corporation’s Air & Liquid Systems Corporation subsidiary (“Asbestos Liability”) and of an inactive subsidiary in dissolution and another former division of the Corporation. Those subsidiaries, and in some cases the Corporation, are defendants (among a number of defendants, typically over 50) in cases filed in various state and federal courts.

Asbestos Claims

The following table reflects approximate information about the claims for Asbestos Liability against the subsidiaries and the Corporation, along with certain asbestos claims asserted against the inactive subsidiary in dissolution and the former division, for the three months ended March 31, 2011:

A substantial majority of the settlement and defense costs reflected in the above table were reported and paid by insurers. Because claims are often filed and can be settled or dismissed in large groups, the amount and timing of settlements, as well as the number of open claims, can fluctuate significantly from period to period. In 2006, for the first time, a claim for Asbestos Liability against one of the Corporation’s subsidiaries was tried to a jury. The trial resulted in a defense verdict. Plaintiffs appealed that verdict and in 2008 the California Court of Appeals reversed the jury verdict and remanded the case back to the trial court.

Asbestos Insurance

Certain of the Corporation’s subsidiaries and the Corporation have an arrangement (the “Coverage Arrangement”) with insurers responsible for historical primary and some first-layer excess insurance coverage for Asbestos Liability (the “Paying Insurers”). Under the Coverage Arrangement, the Paying Insurers accept financial responsibility, subject to the limits of the policies and based on fixed defense percentages and specified indemnity allocation formulas, for pending and future claims for Asbestos Liability. The claims against the Corporation’s inactive subsidiary that is in dissolution proceedings, numbering approximately 480 as of March 31, 2011, are not included within the Coverage Arrangement. The one claim filed against the former division also is not included within the Coverage Arrangement. The Corporation believes that the claims against the inactive subsidiary in dissolution and the former division are immaterial.

The Coverage Arrangement includes an acknowledgement that Howden North America, Inc. (“Howden”) is entitled to coverage under policies covering Asbestos Liability for claims arising out of the historical products manufactured or distributed by Buffalo Forge, a former subsidiary of the Corporation (the “Products”). The Coverage Arrangement does not provide for any prioritization on access to the applicable policies or monetary cap other than the limits of the policies, and, accordingly, Howden may access the policies at any time for any covered claim arising out of a Product. In general, access by Howden to the policies covering the Products will erode the coverage under the policies available to the Corporation and the relevant subsidiaries for Asbestos Liability alleged to arise out of not only the Products but also other historical products of the Corporation and its subsidiaries covered by the applicable policies.

On August 4, 2009, Howden filed a lawsuit in the United States District Court for the Western District of Pennsylvania. In the lawsuit Howden raised claims against certain insurance companies that allegedly issued policies to Howden that do not cover the Corporation or its subsidiaries, and also raised claims against the Corporation and two other insurance companies that issued excess insurance policies covering certain subsidiaries of the Corporation (the “Excess Policies”), but that were not part of the Coverage Arrangement. In the

Table of Contents

lawsuit, Howden seeks, as respects the Corporation, a declaratory judgment from the court as to the respective rights and obligations of Howden, the Corporation and the insurance carriers under the Excess Policies. One of the excess carriers and the Corporation filed cross-claims against each other seeking declarations regarding their respective rights and obligations under Excess Policies issued by that carrier. The Corporation’s cross-claim also sought damages for the carrier’s failure to pay certain defense and indemnity costs. The Corporation and that carrier concluded a settlement generally consistent with the Coverage Arrangement, and all claims between that carrier and the Corporation were dismissed with prejudice on December 8, 2010. In April 2011, the Corporation and the other carrier that issued Excess Policies also concluded a settlement generally consistent with the Coverage Arrangement. The dismissal of the Corporation from this litigation is now in process.

On February 24, 2011, the Corporation and its Air & Liquid Systems Corporation subsidiary filed a lawsuit in the United States District Court for the Western District of Pennsylvania against thirteen domestic insurance companies, certain underwriters at Lloyd’s, London and certain London market insurance companies, and Howden. The lawsuit seeks a declaratory judgment regarding the respective rights and obligations of the parties under excess insurance policies not included within the Coverage Arrangement that were issued to the Corporation from 1981 through 1984 as respects claims against the Corporation and its subsidiary for Asbestos Liability and as respects asbestos bodily-injury claims against Howden arising from the Products.

Asbestos Valuations

In 2006, the Corporation retained Hamilton, Rabinovitz & Associates, Inc. (“HR&A”), a nationally recognized expert in the valuation of asbestos liabilities, to assist the Corporation in estimating the potential liability for pending and unasserted future claims for Asbestos Liability. HR&A was not requested to estimate asbestos claims against the inactive subsidiary in dissolution or the former division, which the Corporation believes are immaterial. Based on this analysis, the Corporation recorded a reserve for Asbestos Liability claims pending or projected to be asserted through 2013 as at December 31, 2006. HR&A’s analysis was updated in 2008, and additional reserves were established by the Corporation as at December 31, 2008 for Asbestos Liability claims pending or projected to be asserted through 2018. HR&A’s analysis was most recently updated in 2010, and additional reserves were established by the Corporation as at December 31, 2010 for Asbestos Liability claims pending or projected to be asserted through 2020. The methodology used by HR&A in its projection in 2010 of the operating subsidiaries’ liability for pending and unasserted potential future claims for Asbestos Liability, which is substantially the same as the methodology employed by HR&A in the 2006 and 2008 estimates, relied upon and included the following factors:

Using this information, HR&A estimated in 2010 the number of future claims for Asbestos Liability that would be filed through the year 2020, as well as the settlement or indemnity costs that would be incurred to resolve both pending and future unasserted claims through 2020. This methodology has been accepted by numerous courts. For purposes of its condensed consolidated financial statements for the three months ended March 31, 2011, the Corporation reviewed its current Asbestos Liability and ultimately utilized the estimate by HR&A completed in 2010, as updated by the Corporation to reflect its Asbestos Liability expenditures through March 31, 2011.

In conjunction with developing the aggregate liability estimate referenced above, the Corporation also developed an estimate of probable insurance recoveries for its Asbestos Liabilities. In developing the estimate, the Corporation considered HR&A’s projection for settlement or indemnity costs for Asbestos Liability and management’s projection of associated defense costs (based on the current defense to indemnity cost ratio), as well as a number of additional factors. These additional factors included the Coverage Arrangement, self-insured retentions, policy exclusions, policy limits, policy provisions regarding coverage for defense costs, attachment points, prior impairment of policies and gaps in the coverage, policy exhaustions, insolvencies among certain of the insurance carriers, the nature of the underlying claims for Asbestos Liability asserted against the subsidiaries

Table of Contents

and the Corporation as reflected in the Corporation’s asbestos claims database, as well as estimated erosion of insurance limits on account of claims against Howden arising out of the Products. In addition to consulting with the Corporation’s outside legal counsel on these insurance matters, the Corporation retained in 2010 a nationally-recognized insurance consulting firm to assist the Corporation with certain policy allocation matters that also are among the several factors considered by the Corporation when analyzing potential recoveries from relevant historical insurance for Asbestos Liabilities. Based upon all of the factors considered by the Corporation, and taking into account the Corporation’s analysis of publicly available information regarding the credit-worthiness of various insurers, the Corporation estimated the probable insurance recoveries for Asbestos Liability and defense costs through 2020. Although the Corporation believes that the assumptions employed in the insurance valuation were reasonable and previously consulted with its outside legal counsel and insurance consultant regarding those assumptions, there are other assumptions that could have been employed that would have resulted in materially lower insurance recovery projections.

Based on the analyses described above, the Corporation’s reserve at December 31, 2010 for the total costs, including defense costs, for Asbestos Liability claims pending or projected to be asserted through 2020 was $218,303,000, of which approximately 85% was attributable to settlement costs for unasserted claims projected to be filed through 2020 and future defense costs. The reserve at March 31, 2011 was $214,981,000. While it is reasonably possible that the Corporation will incur additional charges for Asbestos Liability and defense costs in excess of the amounts currently reserved, the Corporation believes that there is too much uncertainty to provide for reasonable estimation of the number of future claims, the nature of such claims and the cost to resolve them beyond 2020. Accordingly, no reserve has been recorded for any costs that may be incurred after 2020.

The Corporation’s receivable at December 31, 2010 for insurance recoveries attributable to the claims for which the Corporation’s Asbestos Liability reserve has been established, including the portion of incurred defense costs covered by the Coverage Arrangement, and the probable payments and reimbursements relating to the estimated indemnity and defense costs for pending and unasserted future Asbestos Liability claims, was $141,839,000 ($139,202,000 as of March 31, 2011). The insurance receivable recorded by the Corporation does not assume any recovery from insolvent carriers, and substantially all of the insurance recoveries deemed probable were from insurance companies rated A – (excellent) or better by A.M. Best Corporation. There can be no assurance, however, that there will not be further insolvencies among the relevant insurance carriers, or that the assumed percentage recoveries for certain carriers will prove correct. The $76,464,000 difference between insurance recoveries and projected costs at December 31, 2010 is not due to exhaustion of all insurance coverage for Asbestos Liability. The Corporation and the subsidiaries have substantial additional insurance coverage which the Corporation expects to be available for Asbestos Liability claims and defense costs the subsidiaries and it may incur after 2020. However, this insurance coverage also can be expected to have gaps creating significant shortfalls of insurance recoveries as against claims expense, which could be material in future years.

The amounts recorded by the Corporation for Asbestos Liabilities and insurance receivables rely on assumptions that are based on currently known facts and strategy. The Corporation’s actual expenses or insurance recoveries could be significantly higher or lower than those recorded if assumptions used in the Corporation’s or HR&A’s calculations vary significantly from actual results. Key variables in these assumptions are identified above and include the number and type of new claims to be filed each year, the average cost of disposing of each such new claim, average annual defense costs, the resolution of coverage issues with insurance carriers, and the solvency risk with respect to the relevant insurance carriers. Other factors that may affect the Corporation’s Asbestos Liability and ability to recover under its insurance policies include uncertainties surrounding the litigation process from jurisdiction to jurisdiction and from case to case, reforms that may be made by state and federal courts, and the passage of state or federal tort reform legislation.

The Corporation intends to evaluate its estimated Asbestos Liability and related insurance receivables as well as the underlying assumptions on a regular basis to determine whether any adjustments to the estimates are required. Due to the uncertainties surrounding asbestos litigation and insurance, these regular reviews may result in the Corporation incurring future charges; however, the Corporation is currently unable to estimate such future charges. Adjustments, if any, to the Corporation’s estimate of its recorded Asbestos Liability and/or insurance receivables could be material to operating results for the periods in which the adjustments to the liability or receivable are recorded, and to the Corporation’s liquidity and consolidated financial position.

The Corporation is currently performing certain remedial actions in connection with the sale of real estate previously owned and has been named a Potentially Responsible Party at two third-party landfill sites. In addition, as a result of the sale of a segment, the Corporation retained the liability to remediate certain environmental contamination and has agreed to indemnify the buyer against third-party claims arising from the discharge of certain contamination, the costs for which were accrued at the time of sale.

Environmental exposures are difficult to assess and estimate for numerous reasons including lack of reliable data, the multiplicity of possible solutions, the years of remedial and monitoring activity required, and identification of new sites. In the opinion of management and in consideration of advice from the Corporation’s consultants, the potential liability for all environmental proceedings of approximately $1,341,000 at March 31, 2011 is considered adequate based on information known to date.

ITEM 2 - MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Executive Overview

The Corporation operates in two business segments – Forged and Cast Rolls and Air and Liquid Processing. The Forged and Cast Rolls segment produces and sells forged-hardened steel rolls and cast iron and steel rolls to manufacturers of steel and aluminum throughout the world. Business activity for the group has been improving as a result of the global steel industry operating at higher levels when compared to the financial crisis period of 2009 with world-wide steel usage expected to increase in 2011 over 2010 levels. The U.S. Dollar and British Pound Sterling remain relatively weak against most major currencies, particularly against the Euro, thereby aiding export of rolling mill rolls for both our U.S. and U.K. operations. However, excess inventory levels within the industry continue to exist and pricing pressures from customers remain.

For the Air and Liquid Processing group, new construction spending by the institutional markets has yet to exhibit any significant signs of a recovery. The focus for these companies is to continue to search for new product lines and to strengthen their sales distribution networks.

Consolidated Results of Operations for the Three Months Ended March 31, 2011 and 2010

Net Sales. Net sales for the three months ended March 31, 2011 and 2010 were $89,068,000 and $82,326,000, respectively. Backlog approximated $357,283,000 at March 31, 2011 versus $397,030,000 as of December 31, 2010 and $467,796,000 as of March 31, 2010. A discussion of sales and backlog for the Corporation’s two segments is included below.

Costs of Products Sold. Costs of products sold, excluding depreciation, as a percentage of net sales approximated 71.2% and 69.0% for the three months ended March 31, 2011 and 2010, respectively. The increase is primarily attributable to higher direct material and fixed costs particularly for the Forged and Cast Rolls segment.

Selling and Administrative. The decrease in selling and administrative expenses is primarily due to lower stock-based compensation costs offset by higher employee-related costs. Stock-based compensation expense for the three months ended March 31, 2011 and 2010 equaled $348,000 and $1,644,000, respectively.

Depreciation. The increase in depreciation expense is associated with the assets placed in service as a result of the major capital investment program that began in 2008 for the Forged and Cast Rolls segment.

Income from Operations. Income from operations for the three months ended March 31, 2011 and 2010 approximated $12,129,000 and $11,664,000, respectively. A discussion of operating results for the Corporation’s two segments is included below.

Forged and Cast Rolls. Sales for the first quarter 2011 improved against first quarter 2010 as a result of an increase in the volume of shipments. Operating income for the three months ended March 31, 2011 was less than that for the three months ended March 31, 2010 due to higher direct material and fixed costs as well as a shift in product mix and lower pricing. Backlog approximated $308,210,000 at March 31, 2011 against $350,978,000 as of December 31, 2010 and $432,741,000 as of March 31, 2010. The decline is a result of shipments outpacing new orders as customers continue to reduce excess roll inventories which were created years ago. Approximately $137,000,000 of the current backlog is expected to ship after 2011. Additionally, the segment has commitments of approximately $45,000,000 from customers under long-term supply arrangements which will be included in backlog upon receipt of specific purchase orders closer to the requirement dates for delivery.

Air and Liquid Processing. Sales and operating income for the segment increased when compared to the three months ended March 31, 2010. Buffalo Pumps was aided by a higher volume of shipments for the U.S. Navy and Aerofin benefited from an increase in shipments to customers in the fossil fuel utility market. Buffalo Air Handling, however, continues to be impacted by lower capital spending as a result of market consolidation and state budget issues. Additionally, increased competition on projects is compressing margins for this division. As of March 31, 2011, backlog approximated $49,073,000 against $46,052,000 as of December 31, 2010 and $35,055,000 as of March 31, 2010. The improvement in backlog at March 31, 2011 against December 31, 2010 is principally attributable to Aerofin and additional orders for replacement coils for the fossil fuel utility market. The further improvement in backlog at quarter end from a year ago is due to one large order for a customer in the medical industry (Buffalo Air Handling) and a higher volume of pumps for the power generation market (Buffalo Pumps). The majority of the current backlog is expected to ship in 2011.

Other Income (Expense). The fluctuation in other income (expense) when compared to the prior year is primarily attributable to foreign exchange losses during the current year versus foreign exchange gains in the prior year.

Income Taxes. The effective income tax rate for each of the periods approximates 33%.

Net Income and Earnings per Common Share. As a result of the above, the Corporation’s net income for the three months ended March 31, 2011 and 2010 equaled $7,677,000 or $0.74 per common share and $8,211,000 or $0.80 per common share, respectively.

Liquidity and Capital Resources

Net cash flows provided by operating activities decreased for the three months ended March 31, 2011 when compared to the three months ended March 31, 2010. The decrease is principally due to an increase in inventories, particularly for the Forged and Cast Rolls segment, as a result of a higher volume of business activity.

Net cash flows used in investing activities decreased for the three months ended March 31, 2011 when compared to the three months ended March 31, 2010 due to substantial completion of the capital investment program for the Forged and Cast Rolls segment in 2010. In the prior year, UES-UK was awarded a governmental grant of up to $1,325,000 (£850,000) toward the purchase and installation of certain machinery and equipment of which $484,000 (£300,000) was received in 2011 and $226,000 (£145,000) in the third quarter of 2010. As of March 31, 2011, future capital expenditures approximating $15,000,000, to be spent over the next 12-18 months, have been approved.

Net cash flows used in financing activities were comparable for each of the quarters and represented primarily payment of dividends.

The effect of exchange rate changes on cash and cash equivalents is primarily attributable to the movement of the U.K. pound sterling against the U.S. dollar. For the three months ended March 31, 2011, the value of the U.K. pound sterling improved 3% against the U.S. dollar. By comparison, for the three months ended March 31, 2010, the value of the U.K. pound sterling deteriorated 6% against the U.S. dollar.

As a result of the above, cash and cash equivalents increased $951,000 in 2011 and ended the period at $70,972,000 in comparison to $70,021,000 at December 31, 2010.

Funds on hand and funds generated from future operations are expected to be sufficient to finance the operational and capital expenditure requirements of the Corporation. The Corporation also maintains short-term lines of credit and an overdraft facility in excess of the cash needs of its businesses. The total available at March 31, 2011 was approximately $9,400,000 (including £3,000,000 in the U.K. and €400,000 in Belgium).

Forward-Looking Statements

Management’s Discussion and Analysis of Financial Condition and Results of Operations and other sections of the Form 10-Q contain forward-looking statements that reflect the Corporation’s current views with respect to future events and financial performance.

Forward-looking statements are identified by the use of the words “believes,” “expects,” “anticipates,” “estimates,” “projects,” “forecasts” and other expressions that indicate future events and trends. Forward-looking statements speak only as of the date on which such statements are made, are not guarantees of future performance or expectations and involve risks and uncertainties. For the Corporation, these risks and uncertainties include, but are not limited to, those described under Item 1A, Risk Factors, of Part II of this Form 10-Q. In addition, there may be events in the future that the Corporation is not able to accurately predict or control which may cause actual results to differ materially from expectations expressed or implied by forward-looking statements. The Corporation undertakes no obligation to update any forward-looking statement whether as a result of new information, events or otherwise.

ITEM 3 – QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

There were no material changes in the Corporation’s exposure to market risk from December 31, 2010.

ITEM 4 – CONTROLS AND PROCEDURES

(a) Disclosure controls and procedures. An evaluation of the effectiveness of the Corporation’s disclosure controls and procedures as of the end of the period covered by this report was carried out under the supervision, and with the participation, of management, including the principal executive officer and principal financial officer. Disclosure controls and procedures are defined under Securities and Exchange Commission (“SEC”) rules as controls and other procedures that are designed to ensure that information required to be disclosed by a company in the reports that it files under the Exchange Act is recorded, processed, summarized and reported within the required time periods. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Exchange Act is accumulated and communicated to the issuer’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate, to allow timely decisions regarding required disclosure. Based on that evaluation, the Corporation’s management, including the principal executive officer and principal financial officer, has concluded that the Corporation’s disclosure controls and procedures were effective as of March 31, 2011.

(c) Changes in internal control over financial reporting. There were no changes in the Corporation’s internal control over financial reporting during the quarter ended March 31, 2011, that have materially affected, or are reasonably likely to materially affect, its internal control over financial reporting.
