NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

(in thousands, except claim amounts)

1. Unaudited Condensed Consolidated Financial Statements

The condensed consolidated balance sheet as of March 31, 2015 and the condensed consolidated statements of operations, comprehensive income and cash flows for the three months ended March 31, 2015 and 2014 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, 2015 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 Issued Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (FASB) issued ASU 2014-09, Revenue from Contracts with Customers, which provides a common revenue standard for U.S. GAAP and IFRS. The guidance establishes principles for reporting information about the nature, amount, timing and uncertainty of revenue and cash flows arising from a company’s contracts with customers. It requires companies to apply a five-step model when recognizing revenue relating to the transfer of goods or services to customers in an amount that reflects the consideration that the company expects to be entitled to receive for those goods and services. It also requires comprehensive disclosures regarding revenue recognition. The guidance becomes effective January 1, 2017. The Corporation is currently evaluating the impact that the guidance will have on its financial position, operating results and liquidity.

2. Inventories

At March 31, 2015 and December 31, 2014, approximately 60% and 52%, 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:

	March 31, 2015		December 31, 2014
Raw materials	$	16,958	$	15,076
Work-in-process		24,304		20,544
Finished goods		10,800		8,201
Supplies		10,607		10,892
	$	62,669	$	54,713

3. Property, Plant and Equipment

Property, plant and equipment were comprised of the following:

	March 31, 2015			December 31, 2014
Land and land improvements	$	5,223		$	5,209
Buildings		44,485			44,610
Machinery and equipment		258,204			259,406
Construction-in-progress		4,390			2,374
Other		8,760			8,716
		321,062			320,315
Accumulated depreciation		(172,939	)		(170,476	)
	$	148,123		$	149,839

7

Land and buildings of Union Electric Steel UK Limited (“UES-UK”) equal to approximately $2,996 (£2,022) at March 31, 2015 are held as collateral by the trustees of the UES-UK defined benefit pension plan (see Note 5).

4. Other Current Liabilities

Other current liabilities were comprised of the following:

	March 31,  2015		December 31,  2014
Customer-related liabilities	$	12,356	$	11,539
Accrued sales commissions		1,563		1,623
Income taxes payable		41		1,717
Other		7,686		7,329
	$	21,646	$	22,208

Included in customer-related liabilities are costs expected to be incurred with respect to product warranties. Changes in the liability for product warranty claims consisted of the following:

	Three Months Ended March 31,
	2015			2014
Balance at beginning of the period	$	6,672		$	6,899
Satisfaction of warranty claims		(331	)		(731	)
Provision for warranty claims		748			605
Other, primarily impact from changes in foreign currency exchange rates		(153	)		24
Balance at end of the period	$	6,936		$	6,797

5. Pension and Other Postretirement Benefits

Contributions were as follows:

	Three Months Ended March 31,
	2015		2014
U.K. defined benefit pension plan	$	427	$	466
Other postretirement benefits (e.g. net payments)	$	164	$	137
U.K. defined contribution pension plan	$	96	$	92

During the first quarter of 2015, the Executive Committee of the Board of Directors elected to freeze a portion of the U.S. defined benefit pension plan effective July 1, 2015 and replace it with a defined contribution plan which will include employer contributions. The plan change resulted in a remeasurement of the plan liability as of March 31, 2015, reducing the liability by approximately $9,300 and resulting in a curtailment charge of $1,217. Additionally, as a result of the remeasurement, the discount rate was changed from 4.10% to 4.00% increasing the liability by approximately $2,800.

8

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

	Three Months Ended March 31,
U.S. Defined Benefit Pension Plan	2015			2014
Service cost	$	1,130		$	1,000

Interest cost		112			227
Amortization of prior service cost		(168	)		5
Amortization of actuarial loss		58			4
Net benefit costs	$	77		$	500

6. Commitments and Contingent Liabilities

Outstanding standby and commercial letters of credit as of March 31, 2015 approximated $19,157, the majority of which serve as collateral for the Industrial Revenue Bond debt.

In 2010, UES-UK was awarded a government grant of approximately $1,083 (£680) toward the purchase and installation of certain machinery and equipment. 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.

See Note 7 for derivative instruments, Note 12 for litigation and Note 13 for environmental matters.

7. Derivative Instruments

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. As of March 31, 2015, approximately $14,903 of anticipated foreign-denominated sales has been hedged which are covered by cash flow and fair value contracts settling at various dates through May 2016. The fair value of assets held as collateral for the fair value contracts as of March 31, 2015 approximated $741.

Additionally, certain of the divisions of the Air and Liquid Processing segment are 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. At March 31, 2015, approximately 57% or $2,520 of anticipated copper purchases over the next nine months and 38% or $458 of anticipated aluminum purchases over the next six months are hedged.

The Corporation previously entered into foreign currency purchase contracts to manage the volatility associated with Euro-denominated progress payments to be made for certain machinery and equipment. As of December 31, 2010, all contracts had been settled and the underlying fixed assets were placed in service.

9

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 a hedge.

At March 31, 2015, the Corporation has purchase commitments covering 34% or $2,500 of anticipated natural gas usage through March 2017 at one of its subsidiaries. The commitments qualify as normal purchases and, accordingly, are not reflected on the condensed consolidated balance sheet. Purchases of natural gas under previously existing commitments approximated $781 and $574 for the three months ended March 31, 2015 and 2014, respectively.

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

Gains (losses) on foreign exchange transactions included in other income (expense) approximated $(380) and $207 for the three months ended March 31, 2015 and 2014, respectively.

The location and fair value of the foreign currency sales contracts recorded on the condensed consolidated balance sheets were as follows:

	Location	March 31, 2015			December 31, 2014
Cash flow hedge contracts	Other current liabilities	$	14		$	6
Fair value hedge contracts	Other current assets		497			217
	Other noncurrent assets		97			15
	Other current liabilities		594			399
	Other noncurrent liabilities		0			5
Fair value hedged items	Receivables		(60	)		69
	Other current assets		510			327
	Other noncurrent assets		0			4
	Other current liabilities		378			218
	Other noncurrent liabilities		109			35

The change in the fair value of the cash flow contracts is recorded as a component of accumulated other comprehensive loss. The balances as of March 31, 2015 and 2014 and the amount recognized as and reclassified from accumulated other comprehensive loss for each of the periods is summarized below. All amounts are after-tax.

The income tax expense (benefit) associated with the various components of other comprehensive income for the three months ended March 31, 2015 and 2014 is summarized below. Foreign currency translation adjustments exclude the effect of income taxes since earnings of non-U.S. subsidiaries are deemed to be reinvested for an indefinite period of time.

	Three Months Ended March 31,

9. Stock-Based Compensation

In May 2011, the shareholders of the Corporation approved the adoption of the 2011 Omnibus Incentive Plan (“Incentive Plan”) which authorizes the issuance of up to 1,000,000 shares of the Corporation’s common stock for grants of equity-based compensation. Awards under the Incentive Plan may include incentive non-qualified stock options, stock appreciation rights, restricted shares and restricted stock units, performance awards, other stock-based awards or short-term cash incentive awards. Unexercised portions of terminated or forfeited awards are available for new awards. The Incentive Plan is administered by the Compensation Committee of the Board of Directors who has the authority to determine, within the limits of the express provisions of the Incentive Plan, the individuals to whom the awards will be granted; the nature, amount and terms of such awards; and the objectives and conditions for earning such awards. In May 2015, the Compensation Committee granted restricted stock units (RSUs) to select individuals. Each RSU represents the right to receive one share of common stock of the Corporation at a future date after the RSU has become earned and vested, subject to the terms and conditions of an RSU award agreement.

The Incentive Plan also provides for annual grants of shares of the Corporation’s common stock to non-employee directors following the Corporation’s annual shareholder meeting. Each annual director award will be for a number of shares having a fair market value equal to $25 and will be fully vested as of the grant date. In May 2015, 14,310 shares of the Corporation’s common stock were granted to the non-employee directors.

Stock-based compensation expense for the three months ended March 31, 2015 and 2014 equaled $225 and $351, respectively. The related income tax benefit recognized in the condensed consolidated statements of operations for each of the periods was approximately $79 and $123, respectively.

10. Fair Value

The Corporation’s financial assets and liabilities that are reported at fair value in the condensed consolidated balance sheets as of March 31, 2015 and December 31, 2014 were as follows:

11. Business Segments

Presented below are the net sales and income before income taxes for the Corporation’s two business segments. The increase in Other expense, including corporate costs is primarily related to corporate’s portion of the curtailment charge incurred in connection with the partial freezing of the U.S. defined benefit pension plan and foreign exchanges losses incurred in the first quarter of 2015 versus foreign exchange gains in the first quarter of 2014.

12. Litigation (claims not in thousands)

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 subsidiary (“Asbestos Liability”) and of an inactive subsidiary in dissolution. During 2013, all pending claims against the inactive subsidiary in dissolution were settled, dismissed or barred and the dissolution court issued a final order thereby concluding the dissolution proceedings. Those subsidiaries, and in some cases the Corporation, are defendants (among a number of defendants, often in excess of 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 for the three months ended March 31, 2015 and 2014 (2014 includes asbestos claims asserted against the inactive subsidiary in dissolution):

	Three Months Ended March 31,
	2015			2014
Total claims pending at the beginning of the period		8,457			8,319
New claims served		372			393
Claims dismissed		(311	)		(56	)
Claims settled		(120	)		(55	)
Total claims pending at the end of the period (1)		8,398			8,601
Gross settlement and defense costs (in 000’s)	$	5,083		$	6,585
Avg. gross settlement and defense costs per claim resolved (in 000’s)	$	11.79		$	59.32

(1) Included as “open claims” are approximately 1,645 and 1,635 claims as of March 31, 2015 and 2014, respectively, classified in various jurisdictions as “inactive” or transferred to a state or federal judicial panel on multi-district litigation, commonly referred to as the MDL.

14

A substantial majority of the settlement and defense costs reflected in the above table was 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.

Asbestos Insurance

The Corporation and its Air & Liquid subsidiary are parties to a series of settlement agreements (“Settlement Agreements”) with insurers that have coverage obligations for Asbestos Liability (the “Settling Insurers”). Under the Settlement Agreements, the Settling Insurers accept financial responsibility, subject to the terms and conditions of the respective agreements, including overall coverage limits, for pending and future claims for Asbestos Liability. The Settlement Agreements encompass the substantial majority of insurance policies that provide coverage for claims for Asbestos Liability.

The Settlement Agreements include acknowledgements 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 Settlement Agreements do not provide for any prioritization on access to the applicable policies or any sublimits of liability as to Howden or the Corporation and Air & Liquid, and, accordingly, Howden may access the coverage afforded by the Settling Insurers for any covered claim arising out of a Product. In general, access by Howden to the coverage afforded by the Settling Insurers for the Products will erode coverage under the Settlement Agreements available to the Corporation and Air & Liquid for Asbestos Liability.

On February 24, 2011, the Corporation and Air & Liquid 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 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. The Corporation and Air & Liquid have reached Settlement Agreements with all but two of the defendant insurers in the coverage action. Those Settlement Agreements specify the terms and conditions upon which the insurer parties are to contribute to defense and indemnity costs for claims for Asbestos Liability. One of the Settlement Agreements entered into by the Corporation and Air & Liquid also provided for the dismissal of claims, without prejudice, regarding two upper-level excess policies issued by one of the insurers. The Court has entered Orders dismissing all claims in the action filed against each other by the Corporation and Air & Liquid, on the one hand, and by the settling insurers, on the other. Howden also reached an agreement with eight domestic insurers addressing asbestos-related bodily injury claims arising from the Products, and claims as to those insurers and Howden have been dismissed. Various counterclaims, cross claims and third party claims have been filed in the litigation and remain pending although only two domestic insurers and Howden remain in the litigation as to the Corporation and Air & Liquid. On September 27, 2013, the Court issued a memorandum opinion and order granting in part and denying in part cross motions for summary judgment filed by the Corporation and Air & Liquid, Howden, and the insurer parties still in the litigation. The September 27, 2013 ruling is not a final ruling for appellate purposes, but when final it could be appealed by the parties to the litigation. At a hearing on January 13, 2015, the Court ruled that final judgment in accordance with the Court’s prior rulings will be entered in the case. Upon entry of final judgment, the Corporation, Air & Liquid, certain insurers, and Howden may appeal to the United States Court of Appeals for the Third Circuit.

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, 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 of December 31, 2006. HR&A’s analysis has been periodically updated since that time. Most recently, the HR&A analysis was updated in 2014, and additional reserves were established by the Corporation as of December 31, 2014 for Asbestos Liability claims pending or projected to be asserted through 2024. The methodology used by HR&A in its projection in 2014 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 prior estimates, relied upon and included the following factors:

• HR&A’s interpretation of a widely accepted forecast of the population likely to have been exposed to asbestos;

• epidemiological studies estimating the number of people likely to develop asbestos-related diseases;

15

• HR&A’s analysis of the number of people likely to file an asbestos-related injury claim against the subsidiaries and the Corporation based on such epidemiological data and relevant claims history from January 1, 2012 to December 8, 2014;

• an analysis of pending cases, by type of injury claimed and jurisdiction where the claim is filed;

• an analysis of claims resolution history from January 1, 2012 to December 8, 2014 to determine the average settlement value of claims, by type of injury claimed and jurisdiction of filing; and

• an adjustment for inflation in the future average settlement value of claims, at an annual inflation rate based on the Congressional Budget Office’s ten year forecast of inflation.

Using this information, HR&A estimated in 2014 the number of future claims for Asbestos Liability that would be filed through the year 2024, as well as the settlement or indemnity costs that would be incurred to resolve both pending and future unasserted claims through 2024. This methodology has been accepted by numerous courts.

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 Settlement Agreements then in effect, 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, and the nature of the underlying claims for Asbestos Liability asserted against the subsidiaries 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 consulted with a nationally-recognized insurance consulting firm it retained 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 2024. 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, 2014 for the total costs, including defense costs, for Asbestos Liability claims pending or projected to be asserted through 2024 was $189,048 of which approximately 64% was attributable to settlement costs for unasserted claims projected to be filed through 2024 and future defense costs. 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 2024. Accordingly, no reserve has been recorded for any costs that may be incurred after 2024.

The Corporation’s receivable at December 31, 2014 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 Settlement Agreements in effect through December 31, 2014, and the probable payments and reimbursements relating to the estimated indemnity and defense costs for pending and unasserted future Asbestos Liability claims, was $140,651

The following table summarizes activity relating to insurance recoveries.

	Three Months Ended March 31,
	2015			2014
Insurance receivable – asbestos, beginning of the year	$	140,651		$	110,741
Settlement and defense costs paid by insurance carriers		(3,844	)		(5,195	)
Insurance receivable – asbestos, end of the period	$	136,807		$	105,546

The insurance receivable recorded by the Corporation does not assume any recovery from insolvent carriers and a substantial majority of the insurance recoveries deemed probable was 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 difference between insurance recoveries and projected costs 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 that the subsidiaries and it may incur after 2024. 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.

16

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, compliance by relevant parties with the terms of the Settlement Agreements, the resolution of remaining 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.

13. Environmental Matters

The Corporation is currently performing certain remedial actions in connection with the sale of real estate previously owned. 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 $250 at March 31, 2015 is considered adequate based on information known to date.

ITEM 2 – MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

(in thousands, except share and per share amounts)

Executive Overview

Ampco-Pittsburgh Corporation operates in two business segments – the Forged and Cast Engineered Products segment and the Air and Liquid Processing segment. The Forged and Cast Engineered Products segment consists of Union Electric Steel Corporation (“Union Electric Steel” or “UES”) and Union Electric Steel UK Limited (“UES-UK”). Union Electric Steel produces ingot and forged products that service a wide variety of industries globally. It specializes in the production of forged hardened steel rolls used in cold rolling by producers of steel, aluminum and other metals throughout the world. In addition, it produces ingot and open die forged products (“other forging products”) which are used in the gas and oil industry and the aluminum and plastic extrusion industries. Headquartered in Carnegie, Pennsylvania with three manufacturing facilities in Pennsylvania and one in Indiana, UES is one of the largest producers of forged hardened steel rolls in the world. In addition to a few domestic competitors, several major European, South American and Asian manufacturers also compete in both the domestic and foreign markets. UES-UK produces cast rolls for hot and cold strip mills, medium/heavy section mills and plate mills in a variety of iron and steel qualities. It is located in Gateshead, England and is a major supplier of cast rolls to the metalworking industry worldwide. It primarily competes with European, Asian and North and South American companies in both the domestic and foreign markets.

The Air and Liquid Processing segment includes Aerofin, Buffalo Air Handling and Buffalo Pumps, all divisions of Air & Liquid Systems Corporation (“Air and Liquid”), a wholly-owned subsidiary of the Corporation. Aerofin produces custom-engineered finned tube heat exchange coils and related heat transfer products for a variety of industries including fossil fuel and nuclear power generation, automotive, industrial process and HVAC. Buffalo Air Handling produces large custom-designed air handling systems for commercial, institutional and industrial building markets. Buffalo Pumps manufactures centrifugal pumps for the marine defense, refrigeration and power generation industries. The segment has operations in Virginia and New York with headquarters in Pennsylvania. The segment distributes a significant portion of its products through a common independent group of sales offices located throughout the United States and Canada.

The Forged and Cast Engineered Products segment has been operating at levels below capacity due to the worldwide reduction in demand for roll product. Market conditions in the United States and the EU28 countries continue to be difficult. Business opportunities in Asia (particularly China), India and other world regions also remain difficult as a result of indigenous supply enabling purchases to be made domestically at lower pricing than offered by traditional western suppliers. In addition, the strengthening of the U.S. dollar against most major world currencies has further hampered opportunity. With the global steelmaking industry also operating below capacity and the resulting supply demand imbalance in the market place, pricing has suffered and profit margins have decreased. Asian, Indian and Eastern European roll producers have been offering aggressive pricing to gain market share in Western and Middle Eastern markets. Additionally, cost reduction requirements at most steel and aluminum producers throughout our customer base have led them to mandate severe discounts from suppliers. For 2015, we expect demand for rolls to continue to be weak and pricing pressures to remain. Ongoing efforts to diversify our customer base have resulted in expansion of our other forging products. Although currently representing a minor portion of the segment’s business activity, sales of our non-roll products are offsetting some of the effects of constraints currently affecting the roll market and utilizing available production capacity.

Union Electric Steel MG Roll Co., Ltd (“UES-MG”), the Chinese joint venture company in which a subsidiary of UES holds a 49% interest, principally manufactures and sells forged backup rolling mill rolls of a size and weight currently not able to be produced by UES. The joint venture has been adversely impacted by the global economy, with significantly depressed pricing, reduced demand and excess roll inventories of its potential customer base in China - all hindering profitability. Losses have been incurred since 2009, in which we have recognized our share (49%) in our condensed consolidated statements of operations, and are expected to continue in 2015. Additionally, the overall financial strength of the joint venture remains weak with a significant reliance on the 51% partner or entities controlled by the 51% partner to provide financing and working capital. We will continue to monitor the carrying value of this investment ($2,459 at March 31, 2015) to determine if future charges are necessary.

For the Air and Liquid Processing segment, business activity in the centrifugal pump industry continues to be strong while softness in the fossil-fueled and nuclear utility markets is negatively affecting our heat-exchange business. The focus for this segment is to develop new products while strengthening the sales distribution networks.

During the first quarter of 2015, the Executive Committee of the Board of Directors elected to freeze a portion of the U.S. defined benefit pension plan effective July 1, 2015 and replace it with a defined contribution plan which will include employer contributions. The plan change resulted in a remeasurement of the plan liability as of March 31, 2015, reducing the liability by approximately $9,300 and resulting in a curtailment charge of $1,217. Additionally, as a result of the remeasurement, the discount rate was changed from 4.10% to 4.00% increasing the liability by approximately $2,800.

Consolidated Results of Operations for the Three Months Ended March 31, 2015 and 2014

Net sales for the three months ended March 31, 2015 and 2014 were $65,087 and $62,913, respectively. Backlog approximated $159,210 at March 31, 2015 versus $167,948 as of December 31, 2014 and $180,492 as of March 31, 2014. A discussion of sales and backlog for the Corporation’s two segments is included below.

Costs of products sold, excluding depreciation, as a percentage of net sales approximated 80.0% and 79.6% for the three months ended March 31, 2015 and 2014, respectively, and includes $268 of the $1,217 curtailment charge which increased costs of products sold, excluding depreciation, as a percentage of net sales by approximately 0.5%.

Selling and administrative expenses totaled $9,396 (14.4% of net sales) and $9,006 (14.3% of net sales) for the three months ended March 31, 2015 and 2014, respectively. Selling and administrative expenses for the three months ended March 31, 2015 includes $949 of the $1,217 curtailment charge but benefited from collection of accounts receivable previously written off of approximately $750.

Income from operations for the three months ended March 31, 2015 and 2014 approximated $502 and $777, respectively. A discussion of operating results for the Corporation’s two segments is included below.

Forged and Cast Engineered Products. Net sales for the three months ended March 31, 2015 improved from a year ago by approximately $3,200 or 8% principally due to a higher volume of shipments of other forging products offset by a decrease in traditional roll shipments. Net sales were also adversely impacted by a lower weighted-average exchange rate used to translate sales of UES-UK from the British pound sterling to the U.S. dollar which reduced sales by approximately $1,300. Operating income improved from a year ago primarily due to the collection of accounts receivable previously written off of approximately $750. The change in product mix adversely impacted operating income by approximately $200. The change in the weighted-average exchange rates did not have a significant impact on operating income for the current quarter. Backlog approximated $123,109 at March 31, 2015 against $131,118 as of December 31, 2014 and $141,037 as of March 31, 2014. The decline in backlog is due to shipments outpacing new orders as a result of lower demand from roll customers who continue to operate below capacity. Approximately $29,000 of the current backlog is expected to ship after 2015.

Air and Liquid Processing. Net sales for the segment were down approximately $1,000 or 4% for the three months ended March 31, 2015 from March 31, 2014 while operating income was comparable. Net sales of heat exchange coils fell by approximately 12% due to a lower volume of shipments to the fossil-fueled utility and industrial markets. Net sales of pumps grew slightly, at approximately 2% in 2015 from 2014, on a higher volume of shipments of commercial pumps. Revenue for air handlers was comparable to a year ago. Backlog approximated $36,101 at March 31, 2015 against $36,830 as of December 31, 2014 and $39,455 as of March 31, 2014. The majority of backlog will ship in 2015.

Other income (expense) fluctuated primarily as a result of changes in foreign exchange gains and losses. For the first quarter of 2015, losses on foreign exchange transactions approximated $380 and principally resulted from the decrease in the value of the Euro against the U.S. dollar. First quarter of 2014 benefited from foreign exchange gains of approximately $207.

Effective income tax rate decreased for the three months ended March 31, 2015 in comparison to the three months ended March 31, 2014 which included the effect of reducing a state income tax rate at which certain net deferred income tax assets will be realized.

Net income and earnings per common share equaled $ 72 or $0.01 per common share for the three months ended March 31, 2015 in comparison to $78 or $0.01 per common share for the three months ended March 31, 2014.

Liquidity and Capital Resources

Net cash flows provided by (used in) operating activities increased for the three months ended March 31, 2015 when compared to the three months ended March 31, 2014. The majority of the improvement is associated with changes in working capital including lower accounts receivable.

Net cash flows used in investing activities represent primarily capital expenditures for the Forged and Cast Engineered Products segment. As of March 31, 2015, commitments for future capital expenditures approximated $6,500 which is expected to be spent over the next 12-18 months.

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

As a result of the above, cash and cash equivalents decreased $3,099 in 2015 and ended the period at $93,999 (of which approximately $11,300 is held by foreign operations) in comparison to $97,098 at December 31, 2014 (of which approximately $9,479 was held by foreign operations). Repatriation of foreign funds may result in the Corporation accruing and paying additional income tax; however, the majority of such amounts are currently deemed to be permanently reinvested and no additional provision for income tax has been made.

19

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, 2015 was approximately $8,900 (including £3,000 in the U.K. and €400 in Belgium).

The condensed consolidated balance sheet as of March 31, 2015 and the condensed consolidated statements of operations, comprehensive income and cash flows for the three months ended March 31, 2015 and 2014 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, 2015 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 Issued Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (FASB) issued ASU 2014-09, Revenue from Contracts with Customers, which provides a common revenue standard for U.S. GAAP and IFRS. The guidance establishes principles for reporting information about the nature, amount, timing and uncertainty of revenue and cash flows arising from a company’s contracts with customers. It requires companies to apply a five-step model when recognizing revenue relating to the transfer of goods or services to customers in an amount that reflects the consideration that the company expects to be entitled to receive for those goods and services. It also requires comprehensive disclosures regarding revenue recognition. The guidance becomes effective January 1, 2017. The Corporation is currently evaluating the impact that the guidance will have on its financial position, operating results and liquidity.

Litigation

Text Block [Abstract]

Litigation

12. Litigation (claims not in thousands)

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 subsidiary (“Asbestos Liability”) and of an inactive subsidiary in dissolution. During 2013, all pending claims against the inactive subsidiary in dissolution were settled, dismissed or barred and the dissolution court issued a final order thereby concluding the dissolution proceedings. Those subsidiaries, and in some cases the Corporation, are defendants (among a number of defendants, often in excess of 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 for the three months ended March 31, 2015 and 2014 (2014 includes asbestos claims asserted against the inactive subsidiary in dissolution):

	Three Months Ended March 31,
	2015			2014
Total claims pending at the beginning of the period		8,457			8,319
New claims served		372			393
Claims dismissed		(311	)		(56	)
Claims settled		(120	)		(55	)
Total claims pending at the end of the period (1)		8,398			8,601
Gross settlement and defense costs (in 000’s)	$	5,083		$	6,585
Avg. gross settlement and defense costs per claim resolved (in 000’s)	$	11.79		$	59.32

(1) Included as “open claims” are approximately 1,645 and 1,635 claims as of March 31, 2015 and 2014, respectively, classified in various jurisdictions as “inactive” or transferred to a state or federal judicial panel on multi-district litigation, commonly referred to as the MDL.

A substantial majority of the settlement and defense costs reflected in the above table was 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.

Asbestos Insurance

The Corporation and its Air & Liquid subsidiary are parties to a series of settlement agreements (“Settlement Agreements”) with insurers that have coverage obligations for Asbestos Liability (the “Settling Insurers”). Under the Settlement Agreements, the Settling Insurers accept financial responsibility, subject to the terms and conditions of the respective agreements, including overall coverage limits, for pending and future claims for Asbestos Liability. The Settlement Agreements encompass the substantial majority of insurance policies that provide coverage for claims for Asbestos Liability.

The Settlement Agreements include acknowledgements 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 Settlement Agreements do not provide for any prioritization on access to the applicable policies or any sublimits of liability as to Howden or the Corporation and Air & Liquid, and, accordingly, Howden may access the coverage afforded by the Settling Insurers for any covered claim arising out of a Product. In general, access by Howden to the coverage afforded by the Settling Insurers for the Products will erode coverage under the Settlement Agreements available to the Corporation and Air & Liquid for Asbestos Liability.

On February 24, 2011, the Corporation and Air & Liquid 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 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. The Corporation and Air & Liquid have reached Settlement Agreements with all but two of the defendant insurers in the coverage action. Those Settlement Agreements specify the terms and conditions upon which the insurer parties are to contribute to defense and indemnity costs for claims for Asbestos Liability. One of the Settlement Agreements entered into by the Corporation and Air & Liquid also provided for the dismissal of claims, without prejudice, regarding two upper-level excess policies issued by one of the insurers. The Court has entered Orders dismissing all claims in the action filed against each other by the Corporation and Air & Liquid, on the one hand, and by the settling insurers, on the other. Howden also reached an agreement with eight domestic insurers addressing asbestos-related bodily injury claims arising from the Products, and claims as to those insurers and Howden have been dismissed. Various counterclaims, cross claims and third party claims have been filed in the litigation and remain pending although only two domestic insurers and Howden remain in the litigation as to the Corporation and Air & Liquid. On September 27, 2013, the Court issued a memorandum opinion and order granting in part and denying in part cross motions for summary judgment filed by the Corporation and Air & Liquid, Howden, and the insurer parties still in the litigation. The September 27, 2013 ruling is not a final ruling for appellate purposes, but when final it could be appealed by the parties to the litigation. At a hearing on January 13, 2015, the Court ruled that final judgment in accordance with the Court’s prior rulings will be entered in the case. Upon entry of final judgment, the Corporation, Air & Liquid, certain insurers, and Howden may appeal to the United States Court of Appeals for the Third Circuit.

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, 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 of December 31, 2006. HR&A’s analysis has been periodically updated since that time. Most recently, the HR&A analysis was updated in 2014, and additional reserves were established by the Corporation as of December 31, 2014 for Asbestos Liability claims pending or projected to be asserted through 2024. The methodology used by HR&A in its projection in 2014 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 prior estimates, relied upon and included the following factors:

• HR&A’s interpretation of a widely accepted forecast of the population likely to have been exposed to asbestos;

• epidemiological studies estimating the number of people likely to develop asbestos-related diseases;

• HR&A’s analysis of the number of people likely to file an asbestos-related injury claim against the subsidiaries and the Corporation based on such epidemiological data and relevant claims history from January 1, 2012 to December 8, 2014;

• an analysis of pending cases, by type of injury claimed and jurisdiction where the claim is filed;

• an analysis of claims resolution history from January 1, 2012 to December 8, 2014 to determine the average settlement value of claims, by type of injury claimed and jurisdiction of filing; and

• an adjustment for inflation in the future average settlement value of claims, at an annual inflation rate based on the Congressional Budget Office’s ten year forecast of inflation.

Using this information, HR&A estimated in 2014 the number of future claims for Asbestos Liability that would be filed through the year 2024, as well as the settlement or indemnity costs that would be incurred to resolve both pending and future unasserted claims through 2024. This methodology has been accepted by numerous courts.

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 Settlement Agreements then in effect, 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, and the nature of the underlying claims for Asbestos Liability asserted against the subsidiaries 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 consulted with a nationally-recognized insurance consulting firm it retained 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 2024. 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, 2014 for the total costs, including defense costs, for Asbestos Liability claims pending or projected to be asserted through 2024 was $189,048 of which approximately 64% was attributable to settlement costs for unasserted claims projected to be filed through 2024 and future defense costs. 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 2024. Accordingly, no reserve has been recorded for any costs that may be incurred after 2024.

The Corporation’s receivable at December 31, 2014 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 Settlement Agreements in effect through December 31, 2014, and the probable payments and reimbursements relating to the estimated indemnity and defense costs for pending and unasserted future Asbestos Liability claims, was $140,651

The following table summarizes activity relating to insurance recoveries.

	Three Months Ended March 31,
	2015			2014
Insurance receivable – asbestos, beginning of the year	$	140,651		$	110,741
Settlement and defense costs paid by insurance carriers		(3,844	)		(5,195	)
Insurance receivable – asbestos, end of the period	$	136,807		$	105,546

The insurance receivable recorded by the Corporation does not assume any recovery from insolvent carriers and a substantial majority of the insurance recoveries deemed probable was 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 difference between insurance recoveries and projected costs 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 that the subsidiaries and it may incur after 2024. 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, compliance by relevant parties with the terms of the Settlement Agreements, the resolution of remaining 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.

Commitments and Contingent Liabilities

6. Commitments and Contingent Liabilities

Outstanding standby and commercial letters of credit as of March 31, 2015 approximated $19,157, the majority of which serve as collateral for the Industrial Revenue Bond debt.

In 2010, UES-UK was awarded a government grant of approximately $1,083 (£680) toward the purchase and installation of certain machinery and equipment. 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.

Other postretirement benefits (e.g. net payments)	$	164	$	137
U.K. defined contribution pension plan	$	96	$	92

During the first quarter of 2015, the Executive Committee of the Board of Directors elected to freeze a portion of the U.S. defined benefit pension plan effective July 1, 2015 and replace it with a defined contribution plan which will include employer contributions. The plan change resulted in a remeasurement of the plan liability as of March 31, 2015, reducing the liability by approximately $9,300 and resulting in a curtailment charge of $1,217. Additionally, as a result of the remeasurement, the discount rate was changed from 4.10% to 4.00% increasing the liability by approximately $2,800.

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

Environmental Matters

13. Environmental Matters

The Corporation is currently performing certain remedial actions in connection with the sale of real estate previously owned. 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 $250 at March 31, 2015 is considered adequate based on information known to date.

Stock-Based Compensation

9. Stock-Based Compensation

In May 2011, the shareholders of the Corporation approved the adoption of the 2011 Omnibus Incentive Plan (“Incentive Plan”) which authorizes the issuance of up to 1,000,000 shares of the Corporation’s common stock for grants of equity-based compensation. Awards under the Incentive Plan may include incentive non-qualified stock options, stock appreciation rights, restricted shares and restricted stock units, performance awards, other stock-based awards or short-term cash incentive awards. Unexercised portions of terminated or forfeited awards are available for new awards. The Incentive Plan is administered by the Compensation Committee of the Board of Directors who has the authority to determine, within the limits of the express provisions of the Incentive Plan, the individuals to whom the awards will be granted; the nature, amount and terms of such awards; and the objectives and conditions for earning such awards. In May 2015, the Compensation Committee granted restricted stock units (RSUs) to select individuals. Each RSU represents the right to receive one share of common stock of the Corporation at a future date after the RSU has become earned and vested, subject to the terms and conditions of an RSU award agreement.

The Incentive Plan also provides for annual grants of shares of the Corporation’s common stock to non-employee directors following the Corporation’s annual shareholder meeting. Each annual director award will be for a number of shares having a fair market value equal to $25 and will be fully vested as of the grant date. In May 2015, 14,310 shares of the Corporation’s common stock were granted to the non-employee directors.

Stock-based compensation expense for the three months ended March 31, 2015 and 2014 equaled $225 and $351, respectively. The related income tax benefit recognized in the condensed consolidated statements of operations for each of the periods was approximately $79 and $123, respectively.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments

7. Derivative Instruments

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. As of March 31, 2015, approximately $14,903 of anticipated foreign-denominated sales has been hedged which are covered by cash flow and fair value contracts settling at various dates through May 2016. The fair value of assets held as collateral for the fair value contracts as of March 31, 2015 approximated $741.

Additionally, certain of the divisions of the Air and Liquid Processing segment are 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. At March 31, 2015, approximately 57% or $2,520 of anticipated copper purchases over the next nine months and 38% or $458 of anticipated aluminum purchases over the next six months are hedged.

The Corporation previously entered into foreign currency purchase contracts to manage the volatility associated with Euro-denominated progress payments to be made for certain machinery and equipment. As of December 31, 2010, all contracts had been settled and the underlying fixed assets were placed in service.

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 a hedge.

At March 31, 2015, the Corporation has purchase commitments covering 34% or $2,500 of anticipated natural gas usage through March 2017 at one of its subsidiaries. The commitments qualify as normal purchases and, accordingly, are not reflected on the condensed consolidated balance sheet. Purchases of natural gas under previously existing commitments approximated $781 and $574 for the three months ended March 31, 2015 and 2014, respectively.

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

Gains (losses) on foreign exchange transactions included in other income (expense) approximated $(380) and $207 for the three months ended March 31, 2015 and 2014, respectively.

The location and fair value of the foreign currency sales contracts recorded on the condensed consolidated balance sheets were as follows:

	Location	March 31, 2015			December 31, 2014
Cash flow hedge contracts	Other current liabilities	$	14		$	6
Fair value hedge contracts	Other current assets		497			217

	Other noncurrent assets		0			4
	Other current liabilities		378			218

The change in the fair value of the cash flow contracts is recorded as a component of accumulated other comprehensive loss. The balances as of March 31, 2015 and 2014 and the amount recognized as and reclassified from accumulated other comprehensive loss for each of the periods is summarized below. All amounts are after-tax.

Recently Issued Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (FASB) issued ASU 2014-09, Revenue from Contracts with Customers, which provides a common revenue standard for U.S. GAAP and IFRS. The guidance establishes principles for reporting information about the nature, amount, timing and uncertainty of revenue and cash flows arising from a company’s contracts with customers. It requires companies to apply a five-step model when recognizing revenue relating to the transfer of goods or services to customers in an amount that reflects the consideration that the company expects to be entitled to receive for those goods and services. It also requires comprehensive disclosures regarding revenue recognition. The guidance becomes effective January 1, 2017. The Corporation is currently evaluating the impact that the guidance will have on its financial position, operating results and liquidity.
