Note 1 — The Company and Its Accounting Policies:

Graham Corporation (the “Company”), and its operating subsidiaries, is a global designer, manufacturer and supplier of vacuum and heat transfer equipment used in the chemical, petrochemical, petroleum refining, and electric power generating industries. The Company acquired Energy Steel & Supply Co. (“Energy Steel”) in December 2010. Energy Steel is a nuclear code accredited fabrication and specialty machining company which provides products to the nuclear industry. The Company’s significant accounting policies are set forth below.

The Company’s fiscal years ended March 31, 2012, 2011 and 2010 are referred to as fiscal 2012, fiscal 2011 and fiscal 2010, respectively.

Principles of consolidation and use of estimates in the preparation of financial statements

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, Energy Steel, located in Lapeer, Michigan, and Graham Vacuum and Heat Transfer Technology (Suzhou) Co., Ltd., located in China. All intercompany balances, transactions and profits are eliminated in consolidation.

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, as well as the related revenues and expenses during the reporting period. Actual amounts could differ from those estimated.

Translation of foreign currencies

Assets and liabilities of the Company’s foreign subsidiary are translated into U.S. dollars at currency exchange rates in effect at year-end and revenues and expenses are translated at average exchange rates in effect for the year. Gains and losses resulting from foreign currency transactions are included in results of operations. The Company’s sales and purchases in foreign currencies are minimal. Therefore, foreign currency transaction gains and losses are not significant. Gains and losses resulting from translation of foreign subsidiary balance sheets are included in a separate component of stockholders’ equity. Translation adjustments are not adjusted for income taxes since they relate to an investment, which is permanent in nature.

Revenue recognition

Percentage-of-Completion Method

The Company recognizes revenue on all contracts with a planned manufacturing process in excess of four weeks (which approximates 575 direct labor hours) using the percentage-of-completion method. The majority of the Company’s revenue is recognized under this methodology. The Company has established the systems and procedures essential to developing the estimates required to account for contracts using the percentage-of-completion method. The percentage-of-completion method is determined by comparing actual labor incurred to a specific date to management’s estimate of the total labor to be incurred on each contract.

Contracts in progress are reviewed monthly, and sales and earnings are adjusted in current accounting periods based on revisions in the contract value and estimated costs at completion. Losses on contracts are recognized immediately when evident to management. Revenue recognized on contracts accounted for utilizing percentage-of-completion are presented in net sales in the Consolidated Statement of Operations and unbilled revenue in the Consolidated Balance Sheets to the extent that the revenue recognized exceeds the amounts billed to customers. See “Inventories” below.

Completed Contract Method

Revenue on contracts not accounted for using the percentage-of-completion method is recognized utilizing the completed contract method. The majority of the Company’s contracts have a planned manufacturing process of less than four weeks and the results reported under this method do not vary materially from the percentage-of-completion method. The Company recognizes revenue and all related costs on these contracts upon substantial completion or shipment to the customer. Substantial completion is consistently defined as at least 95% complete with regard to direct labor hours. Customer acceptance is generally required throughout the construction process and the Company has no further obligations under the contract after the revenue is recognized.

Cash and cash equivalents

Cash and cash equivalents consist of cash and highly liquid, short-term investments with maturities at the time of purchase of three months or less.

Shipping and handling fees and costs

Shipping and handling fees billed to the customer are recorded in net sales and the related costs incurred for shipping and handling are included in cost of products sold.

Investments

Investments consist of fixed-income debt securities issued by the U.S. Treasury with original maturities of greater than three months and less than one year. All investments are classified as held-to-maturity, as the Company believes it has the intent and ability to hold the securities to maturity. The investments are stated at amortized cost which approximates fair value. All investments held by the Company at March 31, 2012 are scheduled to mature prior to July 5, 2012.

Inventories

Inventories are stated at the lower of cost or market, using the average cost method. For contracts accounted for on the completed contract method, progress payments received are netted against inventory to the extent the payment is less than the inventory balance relating to the applicable contract. Progress payments that are in excess of the corresponding inventory balance are presented as customer deposits in the Consolidated Balance Sheets. Unbilled revenue in the Consolidated Balance Sheets represents revenue recognized that has not been billed to customers on contracts accounted for on the percentage-of-completion method. For contracts accounted for on the percentage-of-completion method, progress payments are netted against unbilled revenue to the extent the payment is less than the unbilled revenue for the applicable contract. Progress payments exceeding unbilled revenue are netted against inventory to the extent the payment is less than or equal to the inventory balance relating to the applicable contract, and the excess is presented as customer deposits in the Consolidated Balance Sheets.

A summary of costs and estimated earnings on contracts in progress at March 31, 2012 and 2011 is as follows:

The above activity is included in the accompanying Consolidated Balance Sheets under the following captions at March 31, 2012 and 2011 or Notes to Consolidated Financial Statements:

Property, plant, equipment and depreciation

Property, plant and equipment are stated at cost net of accumulated depreciation and amortization. Major additions and improvements are capitalized, while maintenance and repairs are charged to expense as incurred. Depreciation and amortization are provided based upon the estimated useful lives, or lease term if shorter, under the straight line method. Estimated useful lives range from approximately five to eight years for office equipment, eight to twenty-five years for manufacturing equipment and forty years for buildings and improvements. Upon sale or retirement of assets, the cost and related accumulated depreciation are removed from the accounts and any resulting gain or loss is included in the results of operations.

Business combinations

The Company records its business combinations under the acquisition method of accounting. Under the acquisition method of accounting, the Company allocates the purchase price of each acquisition to the tangible and identifiable intangible assets acquired and liabilities assumed based on their respective fair values at the date of acquisition. The fair value of identifiable intangible assets is based upon detailed valuations that use various assumptions made by management. Any excess of the purchase price over the fair value of the net tangible and intangible assets acquired is allocated to goodwill. Direct acquisition-related costs are expensed as incurred.

Intangible assets

Acquired intangible assets other than goodwill consist of permits, customer relationships, tradenames and backlog. The Company amortizes its definite-lived intangible assets on a straight-line basis over their estimated useful lives. Estimated useful lives are six months for backlog and fifteen years for customer relationships. All other intangibles have indefinite lives and are not amortized.

Impairment of long-lived assets

The Company assesses the impairment of definite-lived long-lived assets or asset groups when events or changes in circumstances indicate that the carrying value may not be recoverable. Factors that are considered in deciding when to perform an impairment review include: a significant decrease in the market price of the asset or asset group; a significant adverse change in the extent or manner in which a long-lived asset or asset group is being used or in its physical condition; an accumulation of costs significantly in excess of the amount originally expected for the acquisition or construction; a current-period operating or cash flow loss combined with a history of operating or cash flow losses or a projection or forecast that demonstrates continuing losses associated with the use of a long-lived asset or asset group; or a current expectation that, more likely than not, a long-lived asset or asset group will be sold or otherwise disposed of significantly before the end of its previously estimated useful life. The term more likely than not refers to a level of likelihood that is more than 50 percent.

Recoverability potential is measured by comparing the carrying amount of the asset or asset group to its related total future undiscounted cash flows. If the carrying value is not recoverable through related cash flows, the asset or asset group is considered to be impaired. Impairment is measured by comparing the asset or asset group’s carrying amount to its fair value. When it is determined that useful lives of assets are shorter than originally estimated, and no impairment is present, the rate of depreciation is accelerated in order to fully depreciate the assets over their new shorter useful lives.

Goodwill and intangible assets with indefinite lives are tested annually for impairment. The Company assesses goodwill for impairment by comparing the fair value of its reporting units to their carrying amounts. If the fair value of a reporting unit is less than its carrying value, an impairment loss is recorded to the extent that the implied fair value of the goodwill within the reporting unit is less than its carrying value. Fair values for reporting units are determined based on discounted cash flows and market multiples. Indefinite lived intangible assets are assessed for impairment by comparing the fair value of the asset to its carrying value.

Product warranties

The Company estimates the costs that may be incurred under its product warranties and records a liability in the amount of such costs at the time revenue is recognized. The reserve for product warranties is based upon past claims experience and ongoing evaluations of any specific probable claims from customers. A reconciliation of the changes in the product warranty liability is presented in Note 6.

Research and development

Research and development costs are expensed as incurred. The Company incurred research and development costs of $3,197, $2,576 and $3,824 in fiscal 2012, fiscal 2011 and fiscal 2010, respectively.

Income taxes

The Company recognizes deferred income tax assets and liabilities for the expected future tax consequences of events that have been recognized in the Company’s financial statements or tax returns. Deferred income tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities using currently enacted tax rates. The Company evaluates the available evidence about future taxable income and other possible sources of realization of deferred income tax assets and records a valuation allowance to reduce deferred income tax assets to an amount that represents the Company’s best estimate of the amount of such deferred income tax assets that more likely than not will be realized.

The Company accounts for uncertain tax positions using a “more likely than not” recognition threshold. The evaluation of uncertain tax positions is based on factors including, but not limited to, changes in tax law, the measurement of tax positions taken or expected to be taken in tax returns, the effective resolution of matters subject to audit, new audit activity and changes in facts or circumstances related to a tax position. These tax positions are evaluated on a quarterly basis. It is the Company’s policy to recognize any interest related to uncertain tax positions in interest expense and any penalties related to uncertain tax positions in selling, general and administrative expense.

The Company files federal and state income tax returns in several U.S. and non-U.S. domestic and foreign jurisdictions. In most tax jurisdictions, returns are subject to examination by the relevant tax authorities for a number of years after the returns have been filed.

Stock-based compensation

The Company records compensation costs related to stock-based awards based on the estimated fair value of the award on the grant date. Compensation cost is recognized in the Company’s Consolidated Statements of Operations over the applicable vesting period. The Company uses the Black-Scholes valuation model as the method for determining the fair value of its equity awards. For restricted stock awards, the fair market value of the award is determined based upon the closing value of the Company’s stock price on the grant date. The amount of stock-based compensation expense recognized during a period is based on the portion of the awards that are ultimately expected to vest. The Company estimates the forfeiture rate at the grant date by analyzing historical data and revises the estimates in subsequent periods if the actual forfeiture rate differs from the estimates.

Income per share data

Basic income per share is computed by dividing net income by the weighted average number of common shares outstanding for the period. Common shares outstanding include share equivalent units which are contingently issuable shares. Diluted income per share is calculated by dividing net income by the weighted average number of common shares outstanding and, when applicable, potential common shares outstanding during the period. A reconciliation of the numerators and denominators of basic and diluted income per share is presented below:

There were 14, 17 and 17 options to purchase shares of common stock at various exercise prices in fiscal 2012, fiscal 2011 and fiscal 2010, respectively, which were not included in the computation of diluted income per share as the effect would be anti-dilutive.

Cash flow statement

The Company considers all highly liquid investments with an original maturity of three months or less at the time of purchase to be cash equivalents.

Interest paid was $100 in fiscal 2012, $5 in fiscal 2011, and $4 in fiscal 2010. In addition, income taxes paid were $8,111 in fiscal 2012, $2,051 in fiscal 2011, and $3,661 in fiscal 2010.

In fiscal 2012, fiscal 2011, and fiscal 2010, non-cash activities included pension and other postretirement benefit adjustments, net of income tax, of $3,223, $707 and $2,072, respectively. Also, in fiscal 2012 and fiscal 2011, non-cash activities included the issuance of treasury stock valued at $330 and $163, respectively, to the Employee Stock Purchase Plan (See Note 12).

At March 31, 2012, 2011, and 2010, there were $13, $9, and $117, respectively, of capital purchases that were recorded in accounts payable and are not included in the caption “Purchase of property, plant and equipment” in the Consolidated Statements of Cash Flows. In fiscal 2012, fiscal 2011 and fiscal 2010, capital expenditures totaling $205, $23 and $190, respectively, were financed through the issuance of capital leases.

Accumulated other comprehensive income (loss)

Comprehensive income is comprised of net income and other comprehensive income or loss items, which are accumulated as a separate component of stockholders’ equity. For the Company, other comprehensive income or loss items include a foreign currency translation adjustment and pension and other postretirement benefit adjustments.

Fair value measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e. the “exit price”) in an orderly transaction between market participants at the measurement date. The accounting standards for fair values establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The hierarchy is broken down into three levels based on the reliability of inputs as follows:

Level 1 — Valuations based on quoted prices in active markets for identical assets or liabilities that the Company has the ability to access. Since valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these products does not entail a significant degree of judgment.

Level 2 — Valuation is determined from quoted prices for similar assets or liabilities in active markets, quoted prices for identical instruments in markets that are not active or by model-based techniques in which all significant inputs are observable in the market.

Level 3 — Valuations based on inputs that are unobservable and significant to the overall fair value measurement. The degree of judgment exercised in determining fair value is greatest for instruments categorized in Level 3.

The availability of observable inputs can vary and is affected by a wide variety of factors, including, the type of asset/liability, whether the asset/liability is established in the marketplace, and other characteristics particular to the transaction. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes the level in the fair value hierarchy within which the fair value measurement in its entirety falls is determined based on the lowest level input that is significant to the fair value measurement in its entirety.

Fair value is a market-based measure considered from the perspective of a market participant rather than an entity-specific measure. Therefore, even when market assumptions are not readily available, assumptions are required to reflect those that market participants would use in pricing the asset or liability at the measurement date.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of sales and expenses during the reporting period. Actual results could differ materially from those estimates.

Accounting and reporting changes

In the normal course of business, management evaluates all new accounting pronouncements issued by the Financial Accounting Standards Board, the Securities and Exchange Commission, the Emerging Issues Task Force, the American Institute of Certified Public Accountants or any other authoritative accounting body to determine the potential impact they may have on the Company’s consolidated financial statements. In June 2011, the FASB amended its guidance related to the presentation of other comprehensive income. The amended guidance requires the presentation of other comprehensive income and its components either (1) together with the components of net income in one continuous statement of comprehensive income or (2) as a separate statement immediately following the statement of income with equal prominence. The provisions of the amended guidance will be effective for the Company beginning in the first quarter of the fiscal year ending March 31, 2013. Management does not expect any other recently issued accounting pronouncements, which have not already been adopted, to have a material impact on the Company’s consolidated financial statements.
