Summary Of Significant Accounting Policies

2. Summary of Significant Accounting Policies

General

The consolidated financial statements include the accounts of RBC Bearings Incorporated, Roller Bearing Company of America, Inc. ("RBCA") and its wholly-owned subsidiaries, Industrial Tectonics Bearings Corporation ("ITB"), RBC Linear Precision Products, Inc. ("LPP"), RBC Nice Bearings, Inc. ("Nice"), RBC Precision Products - Bremen, Inc. ("Bremen (MBC)"), RBC Precision Products - Plymouth, Inc. ("Plymouth"), RBC Lubron Bearings Systems, Inc. ("Lubron"), Schaublin Holdings S.A. and its wholly-owned subsidiaries ("Schaublin"), RBC de Mexico S DE RL DE CV ("Mexico"), RBC Oklahoma, Inc. ("RBC Oklahoma"), RBC Aircraft Products, Inc. ("API"), Shanghai Representative office of Roller Bearing Company of America, Inc. ("RBC Shanghai"), RBC Southwest Products, Inc. ("SWP"), All Power Manufacturing Co. ("All Power"), RBC Bearings U.K. Limited and its wholly-owned subsidiary Phoenix Bearings Limited ("Phoenix") and RBC CBS Coastal Bearing Services LLC ("CBS"), as well as its Transport Dynamics ("TDC"), Heim ("Heim"), Engineered Components ("ECD"), A.I.D. Company ("AID"), BEMD Company ("BEMD") and PIC Design ("PIC Design") divisions of RBCA. U.S. Bearings ("USB") is a division of SWP and Schaublin USA is a division of Nice. All intercompany balances and transactions have been eliminated in consolidation.

The Company has a fiscal year consisting of 52 or 53 weeks, ending on the Saturday closest to March 31. Based on this policy, fiscal years 2012 and 2011 contained 52 weeks and fiscal year 2010 contained 53 weeks. The Company's net sales and operating income were approximately 1.9% higher in fiscal 2010 as a result of the extra week. The amounts are shown in thousands, unless otherwise indicated.

The Company has performed a review of subsequent events through the date of filing.

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles 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 the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Estimates are used for, but not limited to, the accounting for the allowance for doubtful accounts, valuation of inventories, accrued expenses, depreciation and amortization, income taxes and tax reserves, pension and postretirement obligations and the valuation of options.

Cash and Cash Equivalents

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

Inventory

Inventories are stated at the lower of cost or market, using the first-in, first-out method. A reserve against inventory is recorded for obsolete and slow-moving inventory within each class of inventory.

Shipping and Handling

The sales price billed to customers includes shipping and handling, which is included in net sales. The costs to the Company for shipping and handling are included in cost of sales.

Property, Plant and Equipment

Property, plant and equipment are recorded at cost. Depreciation and amortization of property, plant and equipment, including equipment under capital leases, is provided for by the straight-line method over the estimated useful lives of the respective assets or the lease term, if shorter. Depreciation of assets under capital leases is reported within depreciation and amortization. The cost of equipment under capital leases is equal to the lower of the net present value of the minimum lease payments or the fair market value of the leased equipment at the inception of the lease. Expenditures for normal maintenance and repairs are charged to expense as incurred.

The estimated useful lives of the Company's property, plant and equipment follows:

Buildings and improvements	20-30 years
Machinery and equipment	3-15 years
Leasehold improvements	Shorter of the term of lease or estimated useful life

Recognition of Revenue and Accounts Receivable and Concentration of Credit Risk

The Company recognizes revenue only after the following four basic criteria are met:

Persuasive evidence of an arrangement exists;

Delivery has occurred or services have been rendered;

The seller's price to the buyer is fixed or determinable; and

Collectability is reasonably assured.

Revenue is recognized upon the passage of title, which generally is at the time of shipment, except for certain customers for which it occurs when the products reach their destination. Accounts receivable, net of applicable allowances, is recorded when goods are shipped.

The Company sells to a large number of OEMs and distributors who service the aftermarket. The Company's credit risk associated with accounts receivable is minimized due to its customer base and wide geographic dispersion. The Company performs ongoing credit evaluations of its customers' financial condition and generally does not require collateral or charge interest on outstanding amounts. The Company had no concentrations of credit risk with any one customer greater than 5% and 4% of accounts receivables at March 31, 2012 and April 2, 2011, respectively.

Short-Term Investments

The Company held investments in high grade corporate bonds which were classified in the accompanying consolidated balance sheets based upon the long or short term nature of the investment and the Company's intent and ability to hold to maturity. Investment returns comprise dividends, interest, and gains and losses. The investments are required to be recorded at fair value and are classified as available for sale, with all unrealized gains and losses included in accumulated other comprehensive income, net of applicable taxes and other adjustments. The Company regularly reviews investment securities for impairment using both qualitative and quantitative criteria. As of March 31, 2012, the Company did not hold any short-term investments.

Allowance for Doubtful Accounts

The Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. The Company reviews the collectability of its receivables on an ongoing basis taking into account a combination of factors. The Company reviews potential problems, such as past due accounts, a bankruptcy filing or deterioration in the customer's financial condition, to ensure the Company is adequately accrued for potential loss. Accounts are considered past due based on when payment was originally due. If a customer's situation changes, such as a bankruptcy or creditworthiness, or there is a change in the current economic climate, the Company may modify its estimate of the allowance for doubtful accounts. The Company will write-off accounts receivable after reasonable collection efforts have been made and the accounts are deemed uncollectible.

Goodwill

Goodwill (representing the excess of the amount paid to acquire a company over the estimated fair value of the net assets acquired) is not amortized but instead is tested for impairment annually, or when events or circumstances indicate that its value may have declined. This determination of any goodwill impairment is made at the reporting unit level and consists of two steps. First, the Company determines the fair value of a reporting unit and compares it to its carrying amount. Second, if the carrying amount of the reporting unit exceeds its fair value, an impairment loss is recognized for any excess of the carrying amount of the reporting unit's goodwill over the goodwill's implied fair value. The fair value of the Company's reporting units is calculated by comparing the combination of the net present value of future cash flows method (Level 3 inputs) and a market approach method to the reporting units' carrying value. The Company utilizes discount rates determined by management to be similar with the level of risk in its current business model. The Company performs the annual impairment testing during the fourth quarter of each fiscal year and has determined that, to date, no impairment of goodwill exists. Although no changes are expected, if the actual results of the Company are less favorable than the assumptions the Company makes regarding estimated cash flows, the Company may be required to record an impairment charge in the future.

Deferred Financing Costs

Deferred financing costs are amortized by the effective interest method over the lives of the related credit agreements.

Derivative Financial Instruments

The Company utilizes forward contracts and average rate options to mitigate the impact of currency fluctuations on monetary assets and liabilities denominated in currencies other than the applicable functional currency as well as on forecasted transactions denominated in currencies other than the applicable functional currency. The Company does not engage in other uses of these financial instruments. For a financial instrument to qualify as a hedge, the Company must be exposed to interest rate or price risk, and the financial instrument must reduce the exposure and be designated as a hedge. Financial instruments qualifying for hedge accounting must maintain a high correlation between the hedging instrument and the item being hedged, both at inception and throughout the hedged period. The Company measures the effectiveness of the hedging relationship at the inception of the hedge and quarterly at a minimum.

If derivative financial instruments qualify as fair value hedges, the gain or loss on the instrument and the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in current earnings during the period of the change in fair values. For derivative financial instruments that qualify as cash flow hedges (i.e., hedging the exposure to variability in expected future cash flows that is attributable to a particular risk), the effective portion of the gain or loss on the derivative instrument is reported as a component of other comprehensive income and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. The ineffective portion of a cash flow hedge, if any, is determined based on the dollar-offset method (i.e., the gain or loss on the derivative financial instrument in excess of the cumulative change in the present value of future cash flows of the hedged item) and is recognized in current earnings during the period of change. As long as hedge effectiveness is maintained, interest rate swap arrangements and foreign currency exchange agreements qualify for hedge accounting as cash flow hedges.

All derivatives are recorded in the Consolidated Balance Sheets at their fair values. Changes in fair values of derivatives are recorded in each period in comprehensive income, since the derivative is designated and qualifies as a cash flow hedge.

Income Taxes

The Company accounts for income taxes using the liability method, which requires it to recognize a current tax liability or asset for current taxes payable or refundable and a deferred tax liability or asset for the estimated future tax effects of temporary differences between the financial statement and tax reporting bases of assets and liabilities to the extent that they are realizable. Deferred tax expense (benefit) results from the net change in deferred tax assets and liabilities during the year. A valuation allowance is recorded to reduce deferred tax assets to the amount that is more likely than not to be realized.

Temporary differences relate primarily to the timing of deductions for depreciation, goodwill amortization relating to the acquisition of operating divisions, basis differences arising from acquisition accounting, pension and retirement benefits, and various accrued and prepaid expenses. Deferred tax assets and liabilities are recorded at the rates expected to be in effect when the temporary differences are expected to reverse.

Net Income Per Common Share

Basic net income per common share is computed by dividing net income available to common stockholders by the weighted-average number of common shares outstanding.

Diluted net income per common share is computed by dividing net income by the sum of the weighted-average number of common shares, dilutive common share equivalents then outstanding using the treasury stock method. Common share equivalents consist of the incremental common shares issuable upon the exercise of stock options.

The table below reflects the calculation of weighted-average shares outstanding for each year presented as well as the computation of basic and diluted net income per common share:


	Fiscal Year Ended
	March 31, 2012		April 2, 2011		April 3, 2010
Net income	$	49,997	$	34,868	$	24,385
Denominator:
Denominator for basic net income per common share—weighted-average shares		21,880,554		21,678,626		21,590,421
Effect of dilution due to employee stock options		510,360		400,085		156,661
Denominator for diluted net income per common share—adjusted weighted-average shares		22,390,914		22,078,711		21,747,082
Basic net income per common share	$	2.28	$	1.61	$	1.13
Diluted net income per common share	$	2.23	$	1.58	$	1.12

At March 31, 2012, 200,900 employee stock options and 700 restricted shares have been excluded from the calculation of diluted earnings per share. At April 2, 2011, 8,000 employee stock options have been excluded from the calculation of diluted earnings per share. At April 3, 2010, 1,114,700 employee stock options and 98,185 restricted shares were excluded from the calculation of diluted earnings per share. The inclusion of these employee stock options and restricted shares would be anti-dilutive.

Impairment of Long-Lived Assets

The Company assesses the net realizable value of its long-lived assets and evaluates such assets for impairment whenever indicators of impairment are present. For amortizable long-lived assets to be held and used, if indicators of impairment are present, management determines whether the sum of the estimated undiscounted future cash flows is less than the carrying amount. The amount of asset impairment, if any, is based on the excess of the carrying amount over its fair value, which is estimated based on projected discounted future operating cash flows using a discount rate reflecting the Company's average cost of funds. To date, no indicators of impairment exist.

Long-lived assets to be disposed of by sale or other means are reported at the lower of carrying amount or fair value, less costs to sell.

Foreign Currency Translation and Transactions

Assets and liabilities of the Company's foreign operations are translated into U.S. dollars using the exchange rate in effect at the balance sheet date. Results of operations are translated using the average exchange rate prevailing throughout the period. The effects of exchange rate fluctuations on translating foreign currency assets and liabilities into U.S. dollars are included in accumulated other comprehensive income (loss), while gains and losses resulting from foreign currency transactions, which were not material for any of the fiscal years presented, are included in other non-operating expense (income). Net income of the Company's foreign operations for fiscal 2012, 2011 and 2010 amounted to $7,778, $4,705 and $3,310, respectively. Net assets of the Company's foreign operations were $73,230 and $63,928 at March 31, 2012 and April 2, 2011, respectively.

Fair Value of Measurements

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). Inputs used to measure fair value are within a hierarchy consisting of three levels. Level 1 inputs represent unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 inputs represent unadjusted quoted prices in active markets for similar assets or liabilities, or unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability. Level 3 inputs represent unobservable inputs for the asset or liability. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

The financial assets and liabilities that are measured on a recurring basis at March 31, 2012 consist of the Company's forward contracts and average rate options. The Company has measured the fair value of these forward contracts and average rate options using observable market inputs such as spot and forward rates (as provided by the financial institution with which these instruments has been executed). Based on these inputs, these instruments are classified as Level 2 on the valuation hierarchy.

The carrying amounts reported in the balance sheet for cash, accounts receivable, prepaids and other current assets, and accounts payable and accruals approximate their fair value due to their short-term nature.

The carrying amounts of the Company's borrowings under its JP Morgan Credit Agreement and Swiss Credit Facility approximate fair value, as these obligations have interest rates which vary in conjunction with current market conditions.

Accumulated Other Comprehensive Income (Loss)

The components of comprehensive income (loss) that relate to the Company are net income, derivatives, foreign currency translation adjustments and pension plan and postretirement benefits, all of which are presented in the consolidated statements of stockholders' equity and comprehensive income (loss).

The following summarizes the activity within each component of accumulated other comprehensive income (loss):


	Currency Translation			Fair Value of Derivatives			Pension and Postretirement Liability			Investments			Total

Balance at March 31, 2012	$	8,090		$	(14	)	$	(7,007	)	$	—		$	1,069

Stock-Based Compensation

The Company recognizes compensation cost relating to all share-based payment transactions in the financial statements based upon the grant-date fair value of the instruments issued over the requisite service period. The fair value of each option grant was estimated on the date of grant using the Black-Scholes pricing model.

Recent Accounting Pronouncements

In October 2009, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2009-13, "Multiple-Deliverable Revenue Arrangements." This ASU establishes the accounting and reporting guidance for arrangements including multiple revenue-generating activities. This ASU provides amendments to the criteria for separating deliverables, measuring and allocating arrangement consideration to one or more units of accounting. The amendments in this ASU also establish a selling price hierarchy for determining the selling price of a deliverable. Significantly enhanced disclosures are also required to provide information about a vendor's multiple-deliverable revenue arrangements, including information about the nature and terms, significant deliverables, and its performance within arrangements. The amendments also require disclosure of the significant judgments made and changes to those judgments and how the application of the relative selling-price method affects the timing or amount of revenue recognition. The amendments in this ASU are effective prospectively for revenue arrangements entered into or materially modified in the fiscal years beginning on or after June 15, 2010. Early application is permitted. This new ASU did not have an impact on the determination or reporting of the Company's financial results for its fiscal year ended March 31, 2012.

In May 2011, the FASB issued ASU No. 2011-04, "Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs." This update, which will become effective for interim and annual periods beginning after December 15, 2011, requires additional disclosures about the transfers between Level 1 and Level 2 of the fair value hierarchy, the sensitivity of unobservable inputs to the fair value measurements within Level 3 of the fair value hierarchy, and disclosure of the categorization by level of the fair value hierarchy for items for which fair value disclosure is required but that are not measured at fair value in the statement of financial position. The adoption of this ASU did not have an impact on the Company's consolidated financial statements.

In September 2011, the FASB issued ASU No. 2011-05, "Presentation of Comprehensive Income." This update requires that an entity elect to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The entity is required to present on the face of the financial statements reclassification adjustments for items that are reclassified from other comprehensive income to net income in the statement(s) where the components of net income and the components of other comprehensive income are presented. The amendments in this update should be applied retrospectively and are effective for public companies for fiscal years, and interim periods within those years, beginning after December 15, 2011. The adoption of this ASU is not expected to have a material impact on the Company's consolidated financial statements.

In September 2011, the FASB issued ASU 2011-08, "Intangibles – Goodwill and Other (Topic 350) – Testing Goodwill for Impairment (revised standard)." The revised standard is intended to reduce the costs and complexity of the annual goodwill impairment test by providing entities an option to perform a "qualitative" assessment to determine whether further impairment testing is necessary. This ASU is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. The Company will consider this new guidance as it conducts its annual goodwill impairment testing in its fiscal year beginning April 1, 2012 but no material impact is expected.

In December 2011, the FASB issued ASU 2011-12, "Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in ASU 2011-05". This ASU defers the requirement in ASU 2011-05 that companies present reclassification adjustments for each component of accumulated other comprehensive income (AOCI) in both net income and other comprehensive income (OCI) on the face of the financial statements. The effective dates of ASU 2011-12 are consistent with the effective dates of ASU 2011-05, which is effective for public companies for fiscal years, and interim periods within those years, beginning after December 15, 2011. The adoption of this ASU is not expected to have a material impact on the Company's consolidated financial statements.

Acquisitions And Dispositions	12 Months Ended
Acquisitions And Dispositions	Mar. 31, 2012
Acquisitions And Dispositions [Abstract]
Acquisitions And Dispositions	3. Acquisitions and Dispositions On June 28, 2010, RBC France SAS, a subsidiary of Schaublin SA, sold certain assets relating to its J. Bovagnet sales branch. The assets sold included the trade name, inventory, equipment, and a building. Simultaneously, Schaublin SA entered into a long-term distribution agreement for the continued distribution of Schaublin products by the J. Bovagnet sales operation into a defined territory. A gain in the amount of $1,066 was realized from the sale of the assets in fiscal 2011. On September 29, 2009, Lubron acquired certain assets of Lubron Bearing Systems, a manufacturer of highly engineered self-lubricating bearings used in bridge building, power generation, subsea oil production and earthquake seismic isolation, located in Huntington Beach, California for $2,976. The purchase price included $1,943 in cash, a $775 note payable and the assumption of certain liabilities. The purchase price allocation is as follows: inventory ($103), fixed assets ($829), goodwill ($1,713) and intangible assets ($331). The products associated with the acquisition are complementary with products already provided by other Company businesses. Lubron is included in the Plain Bearings segment.

Short-Term Investments	12 Months Ended
Short-Term Investments	Mar. 31, 2012
Short-Term Investments [Abstract]
Short-Term Investments	4. Short-term Investments Short-term investments include corporate bonds that are classified as available-for-sale expected to be sold within the next twelve months. These bonds, with an amortized basis of $0 and $3,804 at March 31, 2012 and April 2, 2011 respectively, were measured at fair value by using quoted prices in active markets for identical assets and were classified as Level 1 of the valuation hierarchy. All such bonds reached their respective maturities as of July 2011. Corporate bonds in the amount of $3,799 were either sold or matured during the fiscal year ended March 31, 2012. As a result, the Company recognized a gain of $84 which was recorded in other non-operating expense in the fiscal period ended March 31, 2012.

- Definition

Tabular disclosure of available-for-sale securities which consist of all investments in certain debt and equity securities neither classified as trading or held-to-maturity securities. A debt security represents a creditor relationship with an enterprise. Debt securities include, among other items, US Treasury securities, US government securities, municipal securities, corporate bonds, convertible debt, commercial paper, and all securitized debt instruments. An equity security represents an ownership interest in an enterprise or the right to acquire or dispose of an ownership interest in an enterprise at fixed or determinable prices. Equity securities include, among other things, common stock, certain preferred stock, warrant rights, call options, and put options, but do not include convertible debt.

Debt [Abstract]

Debt

11. Debt

On November 30, 2010, the Company and RBCA terminated the previous credit agreement and the related credit, security and ancillary agreements, and entered into a new credit agreement (the "JP Morgan Credit Agreement") and related security and guaranty agreements with certain banks, J.P. Morgan Chase Bank, N.A., as Administrative Agent, and J.P. Morgan Chase Bank, N.A. and KeyBank National Association as Co-Lead Arrangers and Joint Lead Book Runners. The JP Morgan Credit Agreement provides RBCA, as borrower, with a $150,000 five-year senior secured revolving credit facility which can be increased by up to $100,000, in increments of $25,000, under certain circumstances and subject to certain conditions (including the receipt from one or more lenders of the additional commitment).

Amounts outstanding under the JP Morgan Credit Agreement generally bear interest at the prime rate or LIBOR plus a specified margin, depending on the type of borrowing being made. The applicable margin is based upon the Company's consolidated ratio of net debt to adjusted EBITDA from time to time. As of March 31, 2012, the Company's margin is 0.5% for prime rate loans and 1.5% for LIBOR rate loans.

On November 30, 2010, the Company borrowed approximately $30,000 under the JP Morgan Credit Agreement and used such funds to repay the approximately $30,000 balance outstanding under the KeyBank Credit Agreement. Amounts outstanding under the new credit agreement are generally due and payable on the expiration date of November 30, 2015. The Company may elect to prepay some or all of the outstanding balance from time to time without penalty.

The JP Morgan Credit Agreement requires the Company to comply with various covenants, including among other things, financial covenants to maintain the following: (1) a ratio of consolidated net debt to adjusted EBITDA not to exceed 3.25 to 1; and (2) a consolidated fixed charge coverage ratio not to exceed 1.5 to 1. The credit agreement allows the Company to, among other things, make distributions to shareholders, repurchase its stock, incur other debt or liens, or acquire or dispose of assets provided that the Company complies with certain requirements and limitations of the agreement. As of March 31, 2012, the Company was in compliance with all such covenants.

Approximately $5,771 of the JP Morgan Credit Agreement is being utilized to provide letters of credit to secure RBCA's obligations relating to certain insurance programs. As of March 31, 2012, RBCA had the ability to borrow up to an additional $144,229 under the JP Morgan Credit Agreement.

On January 8, 2008, the Company entered into an interest rate swap agreement with a total notional value of $30,000 to hedge a portion of its variable rate debt. Under the terms of the agreement, the Company paid interest at a fixed rate (3.64%) and received interest at variable rates. The fair value of this swap at April 2, 2011 was a liability of $240, included in other current liabilities, and was measured using observable market inputs such as yield curves. Based on these inputs, the swap was classified as a Level 2 of the valuation hierarchy. This instrument was designated and qualified as a cash flow hedge. Accordingly, the gain or loss on the hedging instrument was recognized in other comprehensive income and reclassified into earnings contemporaneously with the earnings effect of the hedged transaction. Earnings effect and the hedged item are reported in interest expense. This swap agreement expired on June 24, 2011.

On October 27, 2008, Schaublin entered into a new bank credit facility with Credit Suisse (the "Swiss Credit Facility") which replaced the prior bank credit facility of December 8, 2003 and its amendment of November 8, 2004. This facility provides for up to 4,000 Swiss francs, or $4,428, of revolving credit loans and letters of credit. Borrowings under the Swiss Credit Facility bear interest at Credit Suisse's prevailing prime bank rate. As of March 31, 2012, there were no borrowings under the Swiss Credit Facility.

The balances payable under all borrowing facilities are as follows:


	March 31, 2012		April 2, 2011
JP Morgan Credit Agreement
Five-year senior secured revolving credit facility; amounts outstanding bear interest at LIBOR (0.25% plus a margin of 1.50% at April 2, 2011)	$	—	$	30,000

Total Debt		1,041		31,296
Less: Current Portion		1,041		30,546
Long-Term Debt	$	—	$	750

The current portion of long-term debt as of March 31, 2012 includes a $291 note payable related to the acquisition of Lubron and a $750 note payable related to the AllPower acquisition. During the first quarter of fiscal 2012, the Company paid off the $30,000 outstanding under the revolving credit facility. As a result, the $30,000 borrowing was included in the current portion of long-term debt as of April 2, 2011, along with a $546 note payable related to the acquisition of Lubron.

- Definition

The entire disclosure for information about short-term and long-term debt arrangements, which includes amounts of borrowings under each line of credit, note payable, commercial paper issue, bonds indenture, debenture issue, own-share lending arrangements and any other contractual agreement to repay funds, and about the underlying arrangements, rationale for a classification as long-term, including repayment terms, interest rates, collateral provided, restrictions on use of assets and activities, whether or not in compliance with debt covenants, and other matters important to users of the financial statements, such as the effects of refinancing and noncompliance with debt covenants.

Pension Plans

13. Pension Plans

At March 31, 2012, the Company has one consolidated noncontributory defined benefit pension plan covering union employees in its Heim division plant in Fairfield, Connecticut, its Bremen subsidiary plant in Plymouth, Indiana and former union employees of the Tyson subsidiary in Glasgow, Kentucky and the Nice subsidiary in Kulpsville, Pennsylvania.

Plan assets are comprised primarily of equity and fixed income investments, as follows:


	March 31, 2012		April 2, 2011
Cash and cash equivalents	$	916	$	688
U.S. equity mutual funds		14,026		13,166
Fixed income mutual funds		5,662		5,589
	$	20,604	$	19,443

The fair value of the above investments is determined using quoted market prices of identical instruments. Therefore, the valuation inputs within the fair value hierarchy established by ASC820 are classified as Level 1.

The plan provides benefits of stated amounts based on a combination of an employee's age and years of service. The Company uses a March 31 measurement date for its plan.

The following tables set forth the funded status of the Company's defined benefit pension plan and the amount recognized in the balance sheet at March 31, 2012 and April 2, 2011:


	March 31, 2012			April 2, 2011

Non-current liabilities		(4,839	)		(2,985	)

Amounts recognized in accumulated other comprehensive loss:

Prior service cost	$	170	$	218
Net actuarial loss		10,563		8,022
Accumulated other comprehensive loss	$	10,733	$	8,240

Amounts included in accumulated other comprehensive loss expected to be recognized as components of net periodic benefit cost in 2013:

Prior service cost	$	47
Net actuarial loss		1,093
Total	$	1,140

Benefits under the union plans are not a function of employees' salaries; thus, the accumulated benefit obligation equals the projected benefit obligation.

The following table sets forth net periodic benefit cost of the Company's plan for the three fiscal years in the period ended March 31, 2012:


	Fiscal Year Ended
	March 31, 2012			April 2, 2011			April 3, 2010
Components of net periodic benefit cost:
Service cost	$	359		$	336		$	307
Interest cost		1,166			1,212			1,280
Expected return on plan assets		(1,534	)		(1,525	)		(1,574	)
Amortization of prior service cost		47			53			49
Amortization of losses		822			412			25
Additional amount recognized due to curtailment		—			—			(8	)
Net periodic benefit cost	$	860		$	488		$	79

The assumptions used in determining the net periodic benefit cost information are as follows:


	FY 2012			FY 2011			FY 2010
Discount rate		5.30	%		6.00	%		7.00	%
Expected long-term rate of return on plan assets		8.25	%		8.25	%		8.25	%

The discount rate used in determining the funded status as of March 31, 2012 and April 2, 2011 was 4.20% and 5.30%, respectively.

In developing the overall expected long-term return on plan assets assumption, a building block approach was used in which rates of return in excess of inflation were considered separately for equity securities and debt securities. The excess returns were weighted by the representative target allocation and added along with an appropriate rate of inflation to develop the overall expected long-term return on plan assets assumption.

The Company's investment program objective is to achieve a rate of return on plan assets which will fund the plan liabilities and provide for required benefits while avoiding undue exposure to risk to the plan and increases in funding requirements. The Company's target allocation of plan assets was 60% equity and 40% fixed income as of March 31, 2012 and April 2, 2011.

The following benefit payments, which reflect future service as appropriate, are expected to be paid. The benefit payments are based on the same assumptions used to measure the Company's benefit obligation at the end of fiscal 2012.

2013	$	1,468
2014		1,532
2015		1,565
2016		1,643
2017		1,643
2018-2022		8,442

One of the Company's foreign operations, Schaublin, sponsors a pension plan for its approximately 129 employees in conformance with Swiss pension law. The plan is funded with a reputable (S&P rating AA-) Swiss insurer. Through the insurance contract, the Company has effectively transferred all investment and mortality risk to the insurance company, which guarantees the federally mandated annual rate of return and the conversion rate at retirement. As a result, the plan has no unfunded liability; the interest cost is exactly offset by actual return. Thus, the net periodic cost is equal to the amount of annual premium paid by the Company. For fiscal years 2012, 2011 and 2010, the Company made contribution and premium payments equal to $765, $621 and $644, respectively.

The Company also has a defined contribution plan under Section 401(k) of the Internal Revenue Code for all of its employees not covered by a collective bargaining agreement. The Company had temporarily suspended the employer contribution to this plan effective January 1, 2009. At the beginning of fiscal year 2011, the Company resumed employer contributions which equaled 10% of the first 3.5% of eligible employee compensation. Employer contributions under this plan amounted to $338, $316 and $0 in fiscal 2012, 2011 and 2010, respectively.

Effective September 1, 1996, the Company adopted a non-qualified Supplemental Executive Retirement Plan ("SERP") for a select group of highly compensated management employees designated by the Board of Directors of the Company. The SERP allowed eligible employees to elect to defer, until termination of their employment, the receipt of up to 25% of their salary. In August 2008, the plan was modified, allowing eligible employees to elect to defer up to 75% of their current salary and up to 100% of bonus compensation. The Company had temporarily suspended the employer contribution to this plan effective January 1, 2009 and contributions remained suspended during fiscal 2010 and fiscal 2011. At the beginning of fiscal year 2012, the Company resumed employer contributions which equaled the lesser of 25% of the deferrals, or 1.75% of the employee's annual salary, which vest in full after one year of service following the effective date of the SERP. Employer contributions under this plan amounted to $123 in fiscal 2012.

The Company measures its plans as of the last day of the fiscal year.

The plans contractually limit the benefit to be provided for certain groups of current and future retirees. As a result, there is no health care trend associated with these groups. The discount rate used in determining the accumulated postretirement benefit obligation was 4.20% at March 31, 2012 and 5.30% at April 2, 2011. The discount rate used in determining the net periodic benefit cost was 5.30% for fiscal 2012, 6.00% for fiscal 2011 and 7.00% for fiscal 2010. The RP-2000 Combined Mortality Table was used to determine the postretirement net periodic benefit costs in fiscal 2012, 2011 and 2010.

Net deferred tax assets	$	4,421		$	2,554

A valuation allowance has been recorded on certain state net operating losses as it is more likely than not that these losses will not be utilized.

The Company has determined that its undistributed foreign earnings of approximately $52,500 at March 31, 2012 will be re-invested indefinitely based upon the need for cash in its foreign operations, potential foreign acquisitions and the Company's inability to remit cash back to the United States under its current foreign debt obligations. Schaublin had a tax holiday which expired in March 2010 that provided a 75% reduction of the statutory rate relating to its Swiss facility. This resulted in a tax benefit of approximately $1,000 in fiscal 2010. Schaublin has received a new favorable tax arrangement in Switzerland pertaining to the acceleration of depreciation which results in a tax benefit of approximately $795 in fiscal 2012.

As the Company's undistributed earnings in foreign subsidiaries are considered to be reinvested indefinitely, no provision for U.S. federal and state income taxes has been provided. Upon repatriation of those earnings, in the form of dividends or otherwise, the Company would be subject to both U.S. income taxes (subject to an adjustment of foreign tax credits) and withholding taxes payable to various foreign countries. Determination of the amount of unrecognized deferred U.S. income tax liability is not practicable due to the complexities associated with its hypothetical calculation.

At March 31, 2012, the Company has state net operating losses in different jurisdictions at varying amounts up to $17,749, which expire at various dates through 2026.

The Company files income tax returns in the U.S. federal jurisdiction, and various states and foreign jurisdictions. With few exceptions, the Company is no longer subject to state or foreign income tax examinations by tax authorities for years ending before March 31, 2002. The Company is no longer subject to U.S. federal tax examination by the Internal Revenue Service for years ending before March 31, 2006. A U.S. federal tax examination by the Internal Revenue Service for the years ended March 31, 2007 and March 31, 2008 was substantially completed during fiscal 2011. As a result, the Company recognized certain previously unrecognized tax benefits of $576 in fiscal 2011 on the basis that the related tax positions have been effectively settled.

A reconciliation of the beginning and ending amount of unrecognized tax benefits are as follows:

Balance at April 3, 2010	$	8,209
Increases for tax positions taken during the current period		1,355
Decrease due to a settlement with taxing authorities		(576	)
Balance at April 2, 2011		8,988
Increases for tax positions taken during the current period		986
Balance at March 31, 2012	$	9,974

The increase in tax positions is a result of federal tax credits and state income taxes. The decrease in tax positions in the Company's fiscal year ending April 2, 2011 is due to the conclusion of an IRS audit. Substantially all of the Company's unrecognized tax benefits would impact the effective tax rate if recognized.

The Company recognizes the interest and penalties accrued related to unrecognized tax benefits in income tax expense. The Company recognized charges of $166 and $529 of interest and penalties on its statement of operations for the fiscal years ended March 31, 2012 and April 2, 2011, respectively. The Company has approximately $1,233 and $1,068 of accrued interest and penalties at March 31, 2012 and April 2, 2011, respectively.

The Company believes it is reasonably possible that some of its unrecognized tax positions may be effectively settled by the end of the Company's fiscal year ending March 30, 2013 due to the closing of audits and the statute of limitations expiring in varying jurisdictions. The decrease, pertaining primarily to credits and state tax, is estimated to be between $5,400 and $5,800.

The American Recovery and Reinvestment Act of 2009 provides for a new Advanced Energy Manufacturing Credit under Internal Revenue Code 48C ("Section 48C credit"). This 30% investment credit on qualified property is a collaborative effort of the Internal Revenue Service and the Department of Energy. Its purpose is to encourage the re-equipment, expansion, or establishment of a manufacturing facility for the production of qualified advanced energy property. This Section 48C credit is generally allowed in the taxable year in which the eligible property is placed in service by the taxpayer. On January 7, 2010, the Company was notified by the Internal Revenue Service that it has received an award of $4,200 related to the recently completed investment in the Company's Houston, Texas facility. This facility was placed in service by the Company in fiscal 2010. As such, the net benefit of this credit was recorded in fiscal 2010.

Stock Option Plans

2001 Stock Option Plan

The RBC Bearings Incorporated (f/k/a Roller Bearing Holding Company, Inc.) 2001 Stock Option Plan was adopted in fiscal 2002 and amended and restated on October 24, 2003. The terms of the 2001 Stock Option Plan provide for the grant of options to purchase up to 1,008,553 shares of common stock to officers and employees of, and consultants (including members of the board of directors) to, the Company and its subsidiaries selected by the CEO to participate in the plan. Options granted may be either incentive stock options (under Section 422 of the Internal Revenue Code) or non-qualified stock options. The 2001 Stock Option Plan, which expired in July 2011, was governed by the Company's board of directors or a committee to which the board of directors delegates its responsibilities. As of March 31, 2012, there were outstanding options to purchase 11,200 shares of common stock granted under the 2001 Stock Option Plan, all of which were exercisable. As of August 15, 2005, the 2001 Stock Option Plan was frozen and no additional stock options will be awarded pursuant to the Plan.

2005 Long-Term Incentive Plan

The 2005 Long-Term Incentive Plan provides for grants of stock options, stock appreciation rights, restricted stock and performance awards. Directors, officers and other employees and persons who engage in services for the Company are eligible for grants under the plan. The purpose of the plan is to provide these individuals with incentives to maximize stockholder value and otherwise contribute to the Company's success and to enable the Company to attract, retain and reward the best available persons for positions of responsibility.

1,139,170 shares of common stock were authorized for issuance under the plan, subject to adjustment in the event of a reorganization, stock split, merger or similar change in the Company's corporate structure or in the outstanding shares of common stock. An amendment to increase the number of shares available for issuance under the 2005 Long-Term Incentive Plan from 1,139,170 to 1,639,170 was approved by shareholder vote in September 2006. A further amendment to increase the number of shares available for issuance under the 2005 Long-Term Incentive Plan from 1,639,170 to 2,239,170 was approved by shareholder vote in September 2007. The Company may grant shares of restricted stock to its employees and directors in the future under the plan. The Company's compensation committee will administer the plan. The Company's board of directors also has the authority to administer the plan and to take all actions that the compensation committee is otherwise authorized to take under the plan. The terms and conditions of each award made under the plan, including vesting requirements, is set forth consistent with the plan in a written agreement with the grantee.

Stock Options. Under the 2005 Long-Term Incentive Plan, the compensation committee or the board may approve the award of grants of incentive stock options and other non-qualified stock options. The compensation committee also has the authority to approve the grant of options that will become fully vested and exercisable automatically upon a change in control. The compensation committee may not, however, approve an award to any one person in any calendar year options to purchase common stock equal to more than 10% of the total number of shares authorized under the plan, and it may not approve an award of incentive options first exercisable in any calendar year whose underlying shares have a fair market value greater than $100,000 determined at the time of grant. The compensation committee will approve the exercise price and term of any option in its discretion; however, the exercise price may not be less than 100% of the fair market value of a share of common stock on the date of grant. In the case of any incentive stock option, the option must be exercised within 10 years of the date of grant. The exercise price of an incentive option awarded to a person who owns stock constituting more than 10% of the Company's voting power may not be less than 110% of such fair market value on such date and the option must be exercised within five years of the date of grant. As of March 31, 2012, there were outstanding options to purchase 1,728,668 shares of common stock granted under the 2005 Long-Term Incentive Plan, 1,247,796 of which were exercisable.

Restricted Stock. Under the 2005 Long-Term Incentive Plan, the compensation committee may approve the award of restricted stock subject to the conditions and restrictions, and for the duration that it determines in its discretion. As of March 31, 2012, there were 152,212 shares of restricted stock outstanding.

Stock Appreciation Rights. The compensation committee may approve the grant of stock appreciation rights, or SARs, subject to the terms and conditions contained in the plan. Under the 2005 Long-Term Incentive Plan, the exercise price of a SAR must equal the fair market value of a share of the Company's common stock on the date the SAR was granted. Upon exercise of a SAR, the grantee will receive an amount in shares of our common stock equal to the difference between the fair market value of a share of common stock on the date of exercise and the exercise price of the SAR, multiplied by the number of shares as to which the SAR is exercised.

Performance Awards. The compensation committee may approve the grant of performance awards contingent upon achievement by the grantee or by the Company, of set goals and objectives regarding specified performance criteria, over a specified performance cycle. Awards may include specific dollar-value target awards, performance units, the value of which is established at the time of grant, and/or performance shares, the value of which is equal to the fair market value of a share of common stock on the date of grant. The value of a performance award may be fixed or fluctuate on the basis of specified performance criteria. A performance award may be paid out in cash and/or shares of common stock or other securities.

Amendment and Termination of the Plan. The board may amend or terminate the 2005 Long-Term Incentive Plan at its discretion, except that no amendment will become effective without prior approval of the Company's stockholders if such approval is necessary for continued compliance with the performance-based compensation exception of Section 162(m) of the Internal Revenue Code or any stock exchange listing requirements. If not previously terminated by the board, the plan will terminate on the tenth anniversary of its adoption.

A summary of the status of the Company's stock options outstanding as of March 31, 2012 and changes during the year then ended is presented below. All cashless exercises of options and warrants are handled through an independent broker.


	Number Of Common Stock Options			Weighted Average Exercise Price		Weighted Average Contractual Life (Years)		Intrinsic Value
Outstanding, April 2, 2011		1,692,052		$	21.75		4.4	$	28,959
Awarded		201,000			37.72
Exercised		(123,684	)		22.74
Forfeitures		(29,500	)		34.57
Outstanding, March 31, 2012		1,739,868		$	23.30		3.9	$	39,716

Exercisable, March 31, 2012		1,258,996		$	20.43		3.4	$	32,354

The fair value for the Company's options was estimated at the date of grant using the Black-Scholes option pricing model with the following weighted-average assumptions, which are updated to reflect current expectations of the dividend yield, expected life, risk-free interest rate and using historical volatility to project expected volatility:


	Fiscal Year Ended
	March 31, 2012			April 2, 2011			April 3, 2010
Dividend yield		0.0	%		0.0	%		0.0	%
Expected weighted-average life (yrs.)		4.8			4.8			4.7
Risk-free interest rate		0.98	%		1.48	%		2.25	%
Expected volatility		47.6	%		47.1	%		39.8	%

The weighted average fair value per share of options granted was $15.43 in fiscal 2012, $13.50 in fiscal 2011 and $8.86 in fiscal 2010.

As of March 31, 2012, there was $5,313 of unrecognized compensation costs related to options which is expected to be recognized over a weighted average period of 3.3 years. The total fair value of options that vested in fiscal 2012, 2011 and 2010 was $12,045, $10,213 and $5,775, respectively. The total intrinsic value of options exercised in fiscal 2012, 2011 and 2010 was $2,393, $2,848 and $364, respectively.

Of the total awards outstanding at March 31, 2012, 1,719,813 are either fully vested or are expected to vest. These shares have a weighted average exercise price of $23.25, an intrinsic value of $39,354, and a weighted average contractual term of 3.9 years.

A summary of the status of the Company's restricted stock outstanding as of March 31, 2012 and changes during the year then ended is presented below.


	Number Of Restricted Stock Shares			Weighted-Average Grant Date Fair Value
Non-vested, April 2, 2011		98,095		$	26.94
Granted		115,600			37.75
Vested		(57,483	)		25.27
Forfeitures		(4,000	)		37.31
Non-vested, March 31, 2012		152,212		$	35.54

The Company recorded $1,001 (net of taxes of $595) in compensation in fiscal 2012 related to restricted stock awards. These awards were valued at the fair market value of the Company's common stock on the date of issuance and are being amortized as expense over the applicable vesting period. Unrecognized expense for restricted stock was $4,557 at March 31, 2012. This cost is expected to be recognized over a weighted average period of approximately 3.9 years.

Commitments And Contingencies [Abstract]

Commitments And Contingencies

17. Commitments and Contingencies

The Company leases facilities under non-cancelable operating leases, which expire on various dates through September 2021, with rental expense aggregating $4,627, $4,560 and $4,186 in fiscal 2012, 2011 and 2010, respectively.

The Company also has non-cancelable operating leases for transportation, computer and office equipment, which expire at various dates. Rental expense for fiscal 2012, 2011 and 2010 aggregated $1,235, $1,324 and $1,295, respectively.

Certain of the above leases are renewable while none contain material contingent rent or concession clauses.

The aggregate future minimum lease payments under operating leases are as follows:

2013	$	4,900
2014		3,983
2015		3,424
2016		1,476
2017		846
2018 and thereafter		2,422

As of March 31, 2012, approximately 12% of the Company's hourly employees in the U.S. and abroad were represented by labor unions.

The Company enters into government contracts and subcontracts that are subject to audit by the government. In the opinion of the Company's management, the results of such audits, if any, are not expected to have a material impact on the cash flows, financial condition or results of operations of the Company.

For fiscal 2012, 2011 and 2010, there were no audits by the government, the results of which, in the opinion of the Company's management, had a material impact on the cash flows, financial condition or results of operations of the Company.

The Company is subject to federal, state and local environmental laws and regulations, including those governing discharges of pollutants into the air and water, the storage, handling and disposal of wastes and the health and safety of employees. The Company also may be liable under the Comprehensive Environmental Response, Compensation, and Liability Act or similar state laws for the costs of investigation and cleanup of contamination at facilities currently or formerly owned or operated by the Company, or at other facilities at which the Company may have disposed of hazardous substances. In connection with such contamination, the Company may also be liable for natural resource damages, government penalties and claims by third parties for personal injury and property damage. Agencies responsible for enforcing these laws have authority to impose significant civil or criminal penalties for non-compliance. The Company believes it is currently in material compliance with all applicable requirements of environmental laws. The Company does not anticipate material capital expenditures for environmental compliance in fiscal years 2013 or 2014.

Investigation and remediation of contamination is ongoing at some of the Company's sites. In particular, state agencies have been overseeing groundwater monitoring activities at the Company's facility in Hartsville, South Carolina and a corrective action plan at the Company's facility in Clayton, Georgia. At Hartsville, the Company is monitoring low levels of contaminants in the groundwater caused by former operations. Plans are currently underway to conclude remediation and monitoring activities. In connection with the purchase of the Fairfield, Connecticut facility in 1996, the Company agreed to assume responsibility for completing clean-up efforts previously initiated by the prior owner. The Company submitted data to the state that the Company believes demonstrates that no further remedial action is necessary, although the state may require additional clean-up or monitoring. In connection with the purchase of the Company's Clayton, Georgia facility, the Company agreed to take assignment of the hazardous waste permit covering such facility and to assume certain responsibilities to implement a corrective action plan concerning the remediation of certain soil and groundwater contamination present at that facility. The corrective action plan is in the early stages. Although there can be no assurance, the Company does not expect the costs associated with the above sites to be material.

There are various claims and legal proceedings against the Company relating to its operations in the normal course of business, none of which the Company believes is material to its cash flows, financial position or results of operations. The Company accrues costs associated with legal and non-income tax matters when they become probable and reasonably estimable. As of March 31, 2012, the estimate for a loss exceeding any amounts already recognized is immaterial. The Company currently maintains insurance coverage for product liability claims.

Reportable Segments [Abstract]

Reportable Segments

19. Reportable Segments

The Company operates through operating segments for which separate financial information is available, and for which operating results are evaluated regularly by the Company's chief operating decision maker in determining resource allocation and assessing performance. Those operating segments with similar economic characteristics and that meet all other required criteria, including nature of the products and production processes, distribution patterns and classes of customers, are aggregated as reportable segments. Certain other operating segments that do not exhibit the common attributes mentioned above and do not meet the quantitative thresholds for separate disclosure are combined and disclosed as "Other".

The Company has four reportable business segments, Plain Bearings, Roller Bearings, Ball Bearings and Other, which are described below. Within the Plain Bearings, Roller Bearings and Ball Bearings reportable segments, we have not aggregated any operating segments. Within the Other reportable segment, we have aggregated operating segments because they do not meet the quantitative threshold for separate disclosure.

Plain Bearings. Plain bearings are produced with either self-lubricating or metal-to-metal designs and consists of several sub-classes, including rod end bearings, spherical plain bearings and journal bearings. Unlike ball bearings, which are used in high-speed rotational applications, plain bearings are primarily used to rectify inevitable misalignments in various mechanical components.

Roller Bearings. Roller bearings are anti-friction bearings that use rollers instead of balls. The Company manufactures four basic types of roller bearings: heavy duty needle roller bearings with inner rings, tapered roller bearings, track rollers and aircraft roller bearings.

Ball Bearings. The Company manufactures four basic types of ball bearings: high precision aerospace, airframe control, thin section and commercial ball bearings which are used in high-speed rotational applications.

Other. Other consists of three operating locations that do not fall into the above segmented categories. The Company's precision machine tool collets provide effective part holding and accurate part location during machining operations. Additionally, the Company provides machining for integrated bearing assemblies and aircraft components for the commercial and defense aerospace markets and tight-tolerance, precision mechanical components for use in the motion control industry.

The accounting policies of the reportable segments are the same as those described in Part II, Item 8. "Financial Statements and Supplementary Data," Note 2 "Summary of Significant Accounting Policies." Segment performance is evaluated based on segment net sales and operating income. Items not allocated to segment operating income include corporate administrative expenses and certain other amounts. Identifiable assets by reportable segment consist of those directly identified with the segment's operations. Corporate assets consist of cash, fixed assets and certain prepaid expenses.

Derivative Instruments	12 Months Ended
Derivative Instruments	Mar. 31, 2012
Derivative Instruments [Abstract]
Derivative Instruments	20. Derivative Instruments The Company utilizes forward contracts and average rate options to mitigate the impact of currency fluctuations on monetary assets and liabilities denominated in currencies other than the applicable functional currency as well as on forecasted transactions denominated in currencies other than the applicable functional currency. These are considered derivative instruments and are recorded as either assets or liabilities which are measured at fair value using models based on observable market inputs such as spot and forward rates and are classified as Level 2 on the valuation hierarchy. For instruments that are designated and qualify as cash flow hedges, the unrealized gains or losses are reported as a component of other comprehensive income ("OCI") and are reclassified from accumulated other comprehensive income ("AOCI") into earnings on the consolidated statement of operations when the hedged transaction affects earnings. As of March 31, 2012, the expected net impact of existing gains or losses to be reclassified from AOCI into earnings in the next twelve months is not material. Notional amounts of the derivative financial instruments qualifying and designated as hedges were $1,401 at March 31, 2012 and $850 at April 2, 2011. These financial instruments have maturities that extend to October 2012. Unrealized losses (gains) related to derivative financial instruments were $12 and $(13) at March 31, 2012 and April 2, 2011, respectively.

- Definition

The entire disclosure for the entity's entire derivative instruments and hedging activities. Describes an entity's risk management strategies, derivatives in hedging activities and non-hedging derivative instruments, the assets, obligations, liabilities, revenues and expenses arising therefrom, and the amounts of and methodologies and assumptions used in determining the amounts of such items.

The Company recognizes revenue only after the following four basic criteria are met:

Persuasive evidence of an arrangement exists;

Delivery has occurred or services have been rendered;

The seller's price to the buyer is fixed or determinable; and

Collectability is reasonably assured.

Short-Term Investments

Short-Term Investments

Allowance For Doubtful Accounts

<div> Allowance for Doubtful Accounts The Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. The Company reviews the collectability of its receivables on an ongoing basis taking into account a combination of factors. The Company reviews potential problems, such as past due accounts, a bankruptcy filing or deterioration in the customer's financial condition, to ensure the Company is adequately accrued for potential loss. Accounts are considered past due based on when payment was originally due. If a customer's situation changes, such as a bankruptcy or creditworthiness, or there is a change in the current economic climate, the Company may modify its estimate of the allowance for doubtful accounts. The Company will write-off accounts receivable after reasonable collection efforts have been made and the accounts are deemed uncollectible.</div>
