Organization and Business		1	Organization and Business
	RBC Bearings Incorporated (the “Company”, collectively with its subsidiaries), is a Delaware corporation. The Company operates in four reportable business segments—roller bearings, plain bearings, ball bearings, other and corporate—in which it manufactures roller bearing components and assembled parts and designs and manufactures high-precision roller and ball bearings. The Company sells to a wide variety of original equipment manufacturers (“OEMs”) and distributors who are widely dispersed geographically. In fiscal 2015, no one customer accounted for more than 6% of the Company’s net sales as compared to no more than 7% and 6% of the Company’s net sales in fiscal 2014 and 2013, respectively. The Company’s segments are further discussed in Part II, Item 8. “Financial Statements and Supplemental Data,” Note 19 “Reportable Segments.”

	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 2015, 2014, and 2013 contained 52 weeks. The amounts are shown in thousands, unless otherwise indicated.
	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. The Company maintains its cash accounts primarily with Bank of America, N.A and Wells Fargo & Company. The balances are insured by the Federal Deposit Insurance Company up to $250. The Company has not experienced any losses in such accounts.
	Inventory
	Inventories are stated at the lower of cost or market value. Cost is determined by the first-in, first-out method. The Company accounts for inventory under a full absorption method, and records adjustments to the value of inventory based upon past sales history and forecasted plans to sell our inventories. The physical condition, including age and quality, of the inventories is also considered in establishing its valuation. These adjustments are estimates, which could vary significantly, either favorably or unfavorably, from actual requirements if future economic conditions, customer inventory levels or competitive conditions differ from our expectations.
	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 revenue is recorded.
	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 4% and 5% of accounts receivables at March 28, 2015 and March 29, 2014, respectively.
	Short-Term Investments
	Short-term investments include equity and fixed-income securities and are measured at fair value by using quoted prices in active markets and are classified as Level 1 of the valuation hierarchy.
	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 Company uses a weighting of the market approach and the income approach (discounted cash flow method) in testing goodwill for impairment. In the market approach, the Company applies performance multiples from comparable public companies, adjusted for relative risk, profitability, and growth considerations, to the reporting units to estimate fair value. The key assumptions used in the discounted cash flow method used to estimate fair value include discount rates, revenue growth rates, terminal growth rates and cash flow projections. Discount rates, growth rates and cash flow projections are the most sensitive and susceptible to change as they require significant management judgment. Discount rates are determined by using a weighted average cost of capital (“WACC”). The WACC considers market and industry data as well as Company-specific risk factors for each reporting unit in determining the appropriate discount rate to be used. The discount rate utilized for each reporting unit is indicative of the return an investor would expect to receive for investing in such a business. Terminal growth rate determination follows common methodology of capturing the present value of perpetual cash flow estimates beyond the last projected period assuming a constant WACC and long-term growth rates. 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 and fair value of the reporting units exceeded the carrying value by approximately 59%. 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. As of March 28, 2015, the Company held no derivatives.
	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 and 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:

	At March 28, 2015, 418,450 employee stock options and no restricted shares have been excluded from the calculation of diluted earnings per share. At March 29, 2014, 193,500 employee stock options and no restricted shares have been excluded from the calculation of diluted earnings per share. At March 30, 2013, 207,700 employee stock options and 300 restricted shares have been 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 other than those resulting in the restructuring charges already recorded.
	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 are included in other non-operating expense (income). Net income of the Company’s foreign operations for fiscal 2015, 2014 and 2013 amounted to $2,474, $10,045, and $6,099, respectively. Net assets of the Company’s foreign operations were $96,545 and $106,553 at March 28, 2015 and March 29, 2014, respectively.
	On January 15, 2015, the Swiss National Bank, removed its three-year-old foreign exchange cap of Swiss Francs 1.20 against the Euro. The new exchange rate was approximately 1.02 at the end of fiscal March. This change in rates has impacted the translation and remeasurement of the financial statements of our Swiss company, Schaublin S.A.. Schaublin S.A. had approximately 16.0 million Euro deposits on their balance sheet. When Euro deposits are re-measured to the functional currency of Swiss Francs, the change in exchange rate is reflected in the income statement in other non-operating expense. Based on the exchange rate at the end of fiscal March, the income statement had a negative impact of approximately $3.1 million in the fourth quarter, and was partially offset by a favorable impact of approximately $0.4 million in other comprehensive income on the balance sheet.
	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 in 2014 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 of the valuation hierarchy. As of March 28, 2015, the Company held no forward contracts or average rate options.
The carrying amounts reported in the balance sheet for cash and cash equivalents, short-term investments, accounts receivable, prepaids and other current assets, and accounts payable and accruals, and other current liabilities 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. The carrying value of the mortgage on our Schaublin building approximates fair value as the rates since entering into the mortgage in fiscal 2013 have not changed.
Accumulated Other Comprehensive Income (Loss)
The components of comprehensive income (loss) that relate to the Company are net income, 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), net of taxes:
		Currency		Pension and		Investments		Total

Balance at March 28, 2015		$	-93	$	-7,677		—	$	-7,770
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 April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2015-04, “Compensation - Retirement Benefits: Practical Expedient for the Measurement Date of an Employer’s Defined Benefit Obligation and Plan Assets.” This ASU permits an entity with a fiscal year-end that doesn’t coincide with a month-end, to measure defined benefit plan assets and obligations using the month end that is closest to the entity’s fiscal year-end and apply that consistently from year to year. The practical expedient requires if a contribution or significant event occurs between the month-end date used to measure the defined benefit plan assets and an entity’s fiscal year end, the entity should adjust the measurement of the defined benefit plan assets and obligations to reflect the effects of those contributions and other significant events. This pronouncement is effective for fiscal and interim periods beginning after December 15, 2015. The adoption of this ASU is not expected to have a material impact on the Company’s consolidated financial statements.
In April 2015, the FASB issued ASU No. 2015-03, “Interest - Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs.” This ASU requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. This pronouncement is effective for fiscal and interim periods beginning after December 15, 2015. Other than requiring a different presentation within the balance sheet, the adoption of this ASU is not expected to have a material impact on the Company’s consolidated financial statements.
In January 2015, the FASB issued ASU No. 2015-01, “Income Statement-Extraordinary and Unusual Items.” This update eliminates the concept of extraordinary items and removes the requirements to separately present extraordinary events. This ASU also requires additional disclosures for items that are both unusual in nature and infrequent in occurrence. This pronouncement is effective for fiscal years and interim periods beginning after December 15, 2015. The adoption of this ASU is not expected to have a material impact on the Company’s consolidated financial statements.
In August 2014, the FASB issued ASU No. 2014-15, “Presentation of Financial Statements-Going Concern.” This update requires management to evaluate whether there are conditions or events that raise substantial doubt about an entity’s ability to continue as a going concern, and requires related footnote disclosures. This pronouncement is effective for fiscal years and interim periods beginning after December 15, 2016. The adoption of this ASU is not expected to have a material impact on the Company’s consolidated financial statements.
In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606),” to clarify existing guidance on revenue recognition. This guidance includes the required steps to achieve the core principle that a company should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. This pronouncement is effective for fiscal years and interim periods beginning after December 15, 2016 with no early adoption permitted. The Company has not determined the effect that the adoption of the pronouncement may have on its financial position and/or results of operations.
In April 2014, the FASB issued ASU No. 2014-08, “Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity.” This update requires additional disclosures about discontinued operations and amends the requirements for reporting discontinued operations. Under this ASU only disposals constituting a major financial or operational impact or that represent a strategic shift should be reported as discontinued operations. This update also requires new disclosures for individually material disposals that do not qualify as discontinued operations. This guidance was adopted by the Company at the beginning of the second quarter of fiscal 2015. The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements.
In July 2013, the FASB issued ASU No. 2013-11, “Income Taxes (Topic 740) - Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists.” This ASU requires that companies net their unrecognized tax benefits against all same-jurisdiction net operating losses or tax credits carryforwards that would be used to settle the position with a tax authority. This standard is effective for all entities that have unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists for fiscal years, and interim periods beginning after December 15, 2013. The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements.

	On April 24, 2015, the Company acquired the Sargent Aerospace & Defense business (“Sargent”) of Dover Corporation (see also Note 20 of Notes to the Consolidated Financial Statements).
	On October 7, 2013, the Company acquired the net assets of Turbine Components Inc. (“TCI”) for approximately $3,925. Located in San Diego, California, TCI is an FAA certified aircraft gas turbine repair station and manufacturer of precision components for aerospace markets. TCI’s net sales for calendar year 2012 were approximately $4,000. The purchase price allocation is as follows: accounts receivable ($585), inventory ($125), fixed assets ($1,231), goodwill ($2,821), intangible assets ($441), other non-current assets ($127), other current liabilities ($641), and noncurrent liabilities ($766). The purchase price allocation, which resulted in goodwill of $2,821, is deductible for tax purposes. TCI is included in the Plain Bearings segment. In connection with the acquisition the Company agreed to a contract for additional contingent consideration that is dependent on the outcome of future events. The fair value of the contingent consideration as of the acquisition date was $766. The contingent consideration is based on a market valuation formula and will be payable five years from the acquisition date. The current fair value of the contingent consideration is determined to be $469 (classified as level 3 of the valuation hierarchy). Proforma net sales and net income inclusive of TCI are not materially different from the amounts reported in the accompanying consolidated statements of operations.
	On August 16, 2013, the Company acquired Climax Metal Products Company (“CMP”) located in Mentor, Ohio for $13,646. The purchase price included $10,672 in cash and $2,974 of debt. CMP is a manufacturer of precision shaft collars, rigid couplings, keyless locking devices, and bearings for the industrial markets. CMP’s net sales for the calendar year 2012 were approximately $14,100. The purchase price allocation is as follows: accounts receivable ($1,206), inventory ($4,509), other current assets ($73), fixed assets ($2,466), goodwill ($5,623), intangible assets ($3,904), other non-current assets ($10), other current liabilities ($2,171), and noncurrent liabilities ($1,974). The purchase price allocation, which resulted in goodwill of $5,623, is not deductible for tax purposes. CMP is included in the Ball Bearings segment. Proforma net sales and net income inclusive of CMP are not materially different from the amounts reported in the accompanying consolidated statements of operations.
	On March 1, 2013, RBCA and SWP acquired Western Precision Aero LLC (“WPA”), a manufacturer of precision components and gears for the aerospace and industrial markets located in Garden Grove, California for $2,628. The purchase price included $1,408 in cash and $1,220 of debt. The purchase price allocation is as follows: accounts receivable ($646), inventory ($1,369), other current assets ($66), fixed assets ($1,290), intangible assets ($645), other non-current assets ($24), other current liabilities ($1,085) and a gain on acquisition ($327). The Company believes that it was able to acquire WPA for less than the fair value of its assets because of (i) the Company’s unique position as a market leader in the aerospace and industrial bearing market and (ii) the seller’s distressed operations. This addition expands the Company’s offering to customers and expands its portfolio into the aerospace and industrial markets. WPA is included in the Plain Bearings segment.

Restructuring of Operations		8	Restructuring of Operations
	In the second quarter of fiscal 2015, the Company reached a decision to consolidate the manufacturing capacity of its United Kingdom (U.K.) facility into its other manufacturing facilities. This decision was based on the Company’s intent to better align manufacturing abilities and product development. The consolidation of this facility into the European and South Carolina operations will strengthen and bring improved manufacturing scale to those operations. As a result the Company recorded a charge of $6,382 associated with the consolidation of operations in the second quarter of fiscal 2015 attributable to the Roller Bearings segment. The $6,382 charge includes $3,707 of inventory rationalization costs, $1,319 in impairment of intangibles, $427 loss on fixed assets disposals, $286 in employee related costs and $643 of other costs related to the consolidation of operations. The inventory rationalization costs were recorded in cost of sales in the income statement. All other costs were recorded under operating expenses in the other, net category of the income statement. The pre-tax charge of $6,382 was offset with an associated tax benefit of $3,131. The Company determined that the market approach was the most appropriate method to estimate the fair value for the inventory and equipment using comparable sales data and actual quotes from potential buyers in the market place. The consolidation of the majority of operations was completed in the second quarter of fiscal 2015. Additional charges of $88 were recorded in the third quarter of fiscal 2015.
	In the fourth quarter of fiscal 2013, the Company consolidated its Texas facility into the South Carolina operation in order to strengthen and bring critical engineering and manufacturing mass to the large bearing product line. As a result, the Company recorded a pre-tax charge of $1,787 in fiscal 2014 and $6,738 in fiscal 2013 under operating expenses in the Other, net category of the income statement associated with this consolidation and restructuring. The Company leased the building to a third party in July 2014.

	In connection with the Sargent Aerospace & Defense acquisition on April 24, 2015, the Company entered into a Credit Agreement (the “Credit Agreement”) and terminated the JP Morgan Credit Agreement (see also Note 20 of Notes to the Consolidated Financial Statements).
	On October 1, 2012, Schaublin purchased the land and building, which it occupied and had been leasing, for 14,067 CHF (approximately $14,910). Schaublin obtained a 20 year fixed rate mortgage of 9,300 CHF (approximately $9,857) at an interest rate of 2.9%. The balance of the purchase price of 4,767 CHF (approximately $5,053) was paid from cash on hand. The balance on this mortgage as of March 28, 2015 was 8,138 CHF, or $8,448.
	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 28, 2015, the Company’s margin was 0.5% for prime rate loans and 1.5% for LIBOR rate loans.
	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 28, 2015, the Company was in compliance with all such covenants.
	Approximately $3,698 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 28, 2015, RBCA had the ability to borrow up to an additional $146,302 under the JP Morgan Credit Agreement, which was terminated on April 24, 2015.
	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 $4,152, 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 28, 2015, there were no borrowings under the Swiss Credit Facility.
	The balances payable under all borrowing facilities are as follows:
			March 28,		March 29,
			2015		2014
	Notes payable		$	9,198	$	10,447
	Total debt			9,198		10,447
	Less: current portion			1,233		1,274
	Long-term debt		$	7,965	$	9,173
	The current portion of long-term debt as of March 28, 2015 includes the current portion of the Schaublin mortgage and a $750 note payable related to the AllPower acquisition. The current portion of long-term debt as of March 29, 2014 includes the current portion of the Schaublin mortgage and a $750 note payable related to the AllPower acquisition.

	At March 28, 2015, 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 28,			March 29,
			2015			2014
	Cash and cash equivalents		$	9,925		$	10,288

	Fixed income mutual funds			4,791			4,573
			$	23,225		$	21,603
	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 ASC 820 are classified as Level 1 of the valuation hierarchy.
	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.

	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 28, 2015:
			Fiscal Year Ended
			March 28,			March 29,			March 30,
			2015			2014			2013
	Components of net periodic benefit cost:
	Service cost		$	265		$	287		$	392
	Interest cost			1,007			991			1,042
	Expected return on plan assets			-1,484			-1,591			-1,628
	Amortization of prior service cost			66			70			47
	Amortization of losses			1,122			1,370			1,164
	Net periodic benefit cost		$	976		$	1,127		$	1,017
	The assumptions used in determining the net periodic benefit cost information are as follows:
			FY 2015				FY 2014				FY 2013
	Discount rate			4.1	%			3.8	%			4.2	%
	Expected long-term rate of return on plan assets			7	%			7.75	%			7.75	%
	The discount rate used in determining the funded status as of March 28, 2015 and March 29, 2014 was 3.40% and 4.10%, 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 long-term target allocation of plan assets is 70% equity and 30% fixed income investments.
	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 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 2015:
	2016		$	1,606
	2017			1,661
	2018			1,684
	2019			1,713
2020			1,742
2021-2025			8,739
Although no contributions are required for fiscal 2016, the Company expects to make cash contributions in the $750 to $1,500 range.
One of the Company’s foreign operations, Schaublin, sponsors a pension plan for its approximately 158 employees in conformance with Swiss pension law. The plan is funded with a reputable (S&P rating A+) 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 2015, 2014 and 2013, the Company made contribution and premium payments equal to $885, $825 and $743, 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. Employer contributions under this plan, equal to 10% of the first 3.5% of eligible employee compensation, amounted to $576, $733 and $688 in fiscal 2015, 2014 and 2013, respectively. The amount for fiscal 2014 included a $300 discretionary match made by the Company.
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 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. Employer contributions under this plan equal 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 $177, $162 and $162 in fiscal 2015, 2014 and 2013, respectively.
The fair value of the investments in the SERP is determined using quoted market prices of identical instruments. Therefore, the valuation inputs within the fair value hierarchy established by ASC 820 are classified as Level 1 of the valuation hierarchy.

	The Company, for the benefit of employees at its Heim, West Trenton, Bremen and PIC facilities and former union employees of its Tyson and Nice subsidiaries, sponsors contributory defined benefit health care plans that provide postretirement medical and life insurance benefits to union employees who have attained certain age and/or service requirements while employed by the Company. The plans are unfunded and costs are paid as incurred. Postretirement benefit obligations are included in “Accrued expenses and other current liabilities” and “Other non-current liabilities” in the consolidated balance sheet.
	The following table set forth the funded status of the Company’s postretirement benefit plans, the amount recognized in the balance sheet at March 28, 2015 and March 29, 2014:

	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 3.40% at March 28, 2015 and 4.10% at March 29, 2014. The discount rate used in determining the net periodic benefit cost was 4.10% for fiscal 2015, 3.80% for fiscal 2014, and 4.20% for fiscal 2013. To determine the postretirement net periodic benefit costs in fiscal 2015 the RP-2014 mortality table was used, and for fiscal 2014 and fiscal 2013 the RP-2000 combined mortality table was used.
	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 2015:

	A valuation allowance has been recorded on certain foreign net operating losses, state credits and state net operating losses as it is more likely than not that these items will not be utilized. For the Company’s fiscal year ended March 28, 2015 the valuation allowance decreased by $1,057 of which $1,104 pertained to a decrease of foreign net operating losses and $47 pertained to an increase of state credits and state net operating losses. For the Company’s fiscal year ended March 29, 2014 the valuation allowance increased by $390 of which $252 pertained to foreign net operating losses and $138 pertained to state credits and state net operating losses.
	The Company has determined that its undistributed foreign earnings of approximately $76,973 at March 28, 2015 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.
	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 28, 2015, the Company has state net operating losses in different jurisdictions at varying amounts up to $7,552, which expire at various dates through 2028.
	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, 2007. The Company is no longer subject to U.S. federal tax examination by the Internal Revenue Service for years ending before March 31, 2012. A U.S. federal tax examination by the Internal Revenue Service for the year ended March 30, 2013 commenced in the second quarter of fiscal 2015 and was completed during fiscal 2016. A U.S. federal tax examination by the Internal Revenue Service for the year ended March 31, 2011 was completed during fiscal 2014.
	A reconciliation of the beginning and ending amount of unrecognized tax benefits are as follows:
			March 28,		March 29,		March 30,
			2015		2014		2013
Balance, beginning of year		$	5,250	$	5,892	$	9,974
Gross increases– tax positions taken during a prior period			-139		768		592
Gross increases– tax positions taken during the current period			1,805		853		536
Decreases due to settlement with taxing authorities			-954		-1,182		-4,636
Decreases due to lapse of the applicable statute of limitations			-448		-1,081		-574
Balance, end of year		$	5,514	$	5,250	$	5,892
If recognized, substantially all of the unrecognized tax benefits for the Company’s fiscal years ended March 28, 2015 and March 29, 2014 would affect the effective income tax rate.
The Company recognizes the interest and penalties accrued related to unrecognized tax benefits in income tax expense. The Company recognized a benefit of $20 and $97 of interest and penalties on its statement of operations for the fiscal years ended March 28, 2015 and March 29, 2014, respectively. The Company has approximately $718 and $738 of accrued interest and penalties at March 28, 2015 and March 29, 2014 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 April 2, 2016 due to the closing of audits and the statute of limitations expiring in varying jurisdictions. The decrease, pertaining primarily to state credits and state tax, is estimated to be $326.

	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 (the “Board”)) 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 or a committee to which the Board delegates its responsibilities. As of March 28, 2015, there were no outstanding options under the 2001 Stock Option Plan. 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 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.
	2013 Long-Term Incentive Plan
	The 2013 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.
	1,500,000 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. 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 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 for 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 28, 2015, there were outstanding options to purchase 919,808 shares of common stock granted under the 2005 Long-Term Incentive Plan, 566,508 of which were exercisable. There were 223,750 outstanding options to purchase shares of common stock granted under the 2013 Long-Term Incentive Plan, none 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 28, 2015, there were 174,285 shares of restricted stock outstanding. Under the 2013 Long-Term Incentive Plan, there were 79,099 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.

	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 28,				March 29,				March 30,

	Risk-free interest rate			1.6	%			1.04	%			0.68	%
	Expected volatility			33.2	%			45.2	%			47.8	%
	The weighted average fair value per share of options granted was $20.15 in fiscal 2015, $20.76 in fiscal 2014 and $18.71 in fiscal 2013.
	As of March 28, 2015, there was $8,778 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 2015, 2014 and 2013 was $14,350, $9,570 and $9,138, respectively. The total intrinsic value of options exercised in fiscal 2015, 2014 and 2013 was $8,045, $6,954 and $23,698, respectively.
	Of the total awards outstanding at March 28, 2015, 1,125,203 are either fully vested or are expected to vest. These shares have a weighted average exercise price of $42.21, an intrinsic value of $37,549, and a weighted average contractual term of 4.3 years.

	The Company leases facilities under non-cancelable operating leases, which expire on various dates through September 2021, with rental expense aggregating $3,444, $3,377 and $3,886 in fiscal 2015, 2014 and 2013, respectively.
	The Company also has non-cancelable operating leases for transportation, computer and office equipment, which expire at various dates. Rental expense for fiscal 2015, 2014 and 2013 aggregated $1,439, $1,622 and $1,349, 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:
	2016		$	3,718
	2017			2,652
	2018			1,788
	2019			880
	2020			831
	2021 and thereafter			1,383
	As of March 28, 2015, approximately 11% 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 2015, 2014 and 2013, 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 2016 or 2017.
	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 ongoing. 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 28, 2015, the estimate for a loss exceeding any amounts already recognized is immaterial. The Company currently maintains insurance coverage for product liability claims.

Segment Reporting [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, the Company has not aggregated any operating segments. Within the Other reportable segment, the Company has 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 gross margin. 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.

Subsequent Events [Abstract]
Subsequent Event		20	Subsequent Event
	On April 24, 2015, the Company acquired the Sargent Aerospace & Defense business (“Sargent”) of Dover Corporation for approximately $500 million financed through a combination of cash on hand and senior debt. With headquarters in Tucson, Arizona, Sargent is a leader in precision-engineered products, solutions and repairs for aircraft airframes and engines, rotorcraft, submarines and land vehicles. Sargent manufactures sells, and services hydraulic valves and actuators, specialty bearings, specialty fasteners, seal rings & alignment joints, and precision components under leading brands including Kahr Bearing, Airtomic, Sonic Industries, Sargent Controls, and Sargent Aerospace & Defense. Annual sales are approximately $195 million and the company has over 750 employees in six facilities in three countries.
	In connection with the Sargent Aerospace & Defense acquisition on April 24, 2015, the Company entered into a Credit Agreement (the “Credit Agreement”) and related Guarantee, Pledge Agreement and Security Agreement with Wells Fargo Bank, National Association, as Administrative Agent, Collateral Agent, Swingline Lender and Letter of Credit Issuer and the other lenders party thereto and terminated the JP Morgan Credit Agreement. The Credit Agreement provides RBCA, as Borrower, with (a) a $200 million term loan facility (the “Term Loan Facility”) and (b) a $350 million revolving credit facility (the “Revolving Credit Facility” and together with the Term Loan Facility, the “Facilities”).
	Amounts outstanding under the Facilities generally bear interest at (a) a base rate determined by reference to the higher of (1) Wells Fargo’s prime lending rate, (2) the federal funds effective rate plus 1/2 of 1% and (3) the one-month LIBOR rate plus 1% or (b) LIBOR rate plus a specified margin, depending on the type of borrowing being made. The applicable margin is based on the Company’s consolidated ratio of total net debt to consolidated EBITDA from time to time. Currently, the Company’s margin is 0.50% for base rate loans and 1.50% for LIBOR rate loans.

	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 2015, 2014, and 2013 contained 52 weeks. The amounts are shown in thousands, unless otherwise indicated.
Use of Estimates	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	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. The Company maintains its cash accounts primarily with Bank of America, N.A and Wells Fargo & Company. The balances are insured by the Federal Deposit Insurance Company up to $250. The Company has not experienced any losses in such accounts.
Inventory	Inventory
	Inventories are stated at the lower of cost or market value. Cost is determined by the first-in, first-out method. The Company accounts for inventory under a full absorption method, and records adjustments to the value of inventory based upon past sales history and forecasted plans to sell our inventories. The physical condition, including age and quality, of the inventories is also considered in establishing its valuation. These adjustments are estimates, which could vary significantly, either favorably or unfavorably, from actual requirements if future economic conditions, customer inventory levels or competitive conditions differ from our expectations.
Shipping and Handling	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
	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	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 revenue is recorded.
	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 4% and 5% of accounts receivables at March 28, 2015 and March 29, 2014, respectively.
Short-Term Investments	Short-Term Investments
	Short-term investments include equity and fixed-income securities and are measured at fair value by using quoted prices in active markets and are classified as Level 1 of the valuation hierarchy.
Allowance for Doubtful Accounts	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
	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 Company uses a weighting of the market approach and the income approach (discounted cash flow method) in testing goodwill for impairment. In the market approach, the Company applies performance multiples from comparable public companies, adjusted for relative risk, profitability, and growth considerations, to the reporting units to estimate fair value. The key assumptions used in the discounted cash flow method used to estimate fair value include discount rates, revenue growth rates, terminal growth rates and cash flow projections. Discount rates, growth rates and cash flow projections are the most sensitive and susceptible to change as they require significant management judgment. Discount rates are determined by using a weighted average cost of capital (“WACC”). The WACC considers market and industry data as well as Company-specific risk factors for each reporting unit in determining the appropriate discount rate to be used. The discount rate utilized for each reporting unit is indicative of the return an investor would expect to receive for investing in such a business. Terminal growth rate determination follows common methodology of capturing the present value of perpetual cash flow estimates beyond the last projected period assuming a constant WACC and long-term growth rates. 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 and fair value of the reporting units exceeded the carrying value by approximately 59%. 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
	Deferred financing costs are amortized by the effective interest method over the lives of the related credit agreements.
Derivative Financial Instruments	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. As of March 28, 2015, the Company held no derivatives.
Income Taxes	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	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 and 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 28,		March 29,		March 30,
			2015		2014		2013
	Net income		$	58,248	$	60,208	$	56,342

	Effect of dilution due to employee stock options			311,121		369,399		409,725
	Denominator for diluted net income per common share—adjusted			23,385,061		23,244,241		22,810,793
	weighted-average shares
	Basic net income per common share		$	2.52	$	2.63	$	2.52
	Diluted net income per common share		$	2.49	$	2.59	$	2.47
	At March 28, 2015, 418,450 employee stock options and no restricted shares have been excluded from the calculation of diluted earnings per share. At March 29, 2014, 193,500 employee stock options and no restricted shares have been excluded from the calculation of diluted earnings per share. At March 30, 2013, 207,700 employee stock options and 300 restricted shares have been 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	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 other than those resulting in the restructuring charges already recorded.
	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	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 are included in other non-operating expense (income). Net income of the Company’s foreign operations for fiscal 2015, 2014 and 2013 amounted to $2,474, $10,045, and $6,099, respectively. Net assets of the Company’s foreign operations were $96,545 and $106,553 at March 28, 2015 and March 29, 2014, respectively.
	On January 15, 2015, the Swiss National Bank, removed its three-year-old foreign exchange cap of Swiss Francs 1.20 against the Euro. The new exchange rate was approximately 1.02 at the end of fiscal March. This change in rates has impacted the translation and remeasurement of the financial statements of our Swiss company, Schaublin S.A.. Schaublin S.A. had approximately 16.0 million Euro deposits on their balance sheet. When Euro deposits are re-measured to the functional currency of Swiss Francs, the change in exchange rate is reflected in the income statement in other non-operating expense. Based on the exchange rate at the end of fiscal March, the income statement had a negative impact of approximately $3.1 million in the fourth quarter, and was partially offset by a favorable impact of approximately $0.4 million in other comprehensive income on the balance sheet.
Fair Value of Measurements	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 in 2014 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 of the valuation hierarchy. As of March 28, 2015, the Company held no forward contracts or average rate options.
	The carrying amounts reported in the balance sheet for cash and cash equivalents, short-term investments, accounts receivable, prepaids and other current assets, and accounts payable and accruals, and other current liabilities 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. The carrying value of the mortgage on our Schaublin building approximates fair value as the rates since entering into the mortgage in fiscal 2013 have not changed.
Accumulated Other Comprehensive Income (Loss)	Accumulated Other Comprehensive Income (Loss)
	The components of comprehensive income (loss) that relate to the Company are net income, 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), net of taxes:
			Currency		Pension and		Investments		Total

Stock-Based Compensation	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	Recent Accounting Pronouncements
	In April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2015-04, “Compensation - Retirement Benefits: Practical Expedient for the Measurement Date of an Employer’s Defined Benefit Obligation and Plan Assets.” This ASU permits an entity with a fiscal year-end that doesn’t coincide with a month-end, to measure defined benefit plan assets and obligations using the month end that is closest to the entity’s fiscal year-end and apply that consistently from year to year. The practical expedient requires if a contribution or significant event occurs between the month-end date used to measure the defined benefit plan assets and an entity’s fiscal year end, the entity should adjust the measurement of the defined benefit plan assets and obligations to reflect the effects of those contributions and other significant events. This pronouncement is effective for fiscal and interim periods beginning after December 15, 2015. The adoption of this ASU is not expected to have a material impact on the Company’s consolidated financial statements.
	In April 2015, the FASB issued ASU No. 2015-03, “Interest - Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs.” This ASU requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. This pronouncement is effective for fiscal and interim periods beginning after December 15, 2015. Other than requiring a different presentation within the balance sheet, the adoption of this ASU is not expected to have a material impact on the Company’s consolidated financial statements.
	In January 2015, the FASB issued ASU No. 2015-01, “Income Statement-Extraordinary and Unusual Items.” This update eliminates the concept of extraordinary items and removes the requirements to separately present extraordinary events. This ASU also requires additional disclosures for items that are both unusual in nature and infrequent in occurrence. This pronouncement is effective for fiscal years and interim periods beginning after December 15, 2015. The adoption of this ASU is not expected to have a material impact on the Company’s consolidated financial statements.
	In August 2014, the FASB issued ASU No. 2014-15, “Presentation of Financial Statements-Going Concern.” This update requires management to evaluate whether there are conditions or events that raise substantial doubt about an entity’s ability to continue as a going concern, and requires related footnote disclosures. This pronouncement is effective for fiscal years and interim periods beginning after December 15, 2016. The adoption of this ASU is not expected to have a material impact on the Company’s consolidated financial statements.
	In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606),” to clarify existing guidance on revenue recognition. This guidance includes the required steps to achieve the core principle that a company should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. This pronouncement is effective for fiscal years and interim periods beginning after December 15, 2016 with no early adoption permitted. The Company has not determined the effect that the adoption of the pronouncement may have on its financial position and/or results of operations.
	In April 2014, the FASB issued ASU No. 2014-08, “Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity.” This update requires additional disclosures about discontinued operations and amends the requirements for reporting discontinued operations. Under this ASU only disposals constituting a major financial or operational impact or that represent a strategic shift should be reported as discontinued operations. This update also requires new disclosures for individually material disposals that do not qualify as discontinued operations. This guidance was adopted by the Company at the beginning of the second quarter of fiscal 2015. The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements.
	In July 2013, the FASB issued ASU No. 2013-11, “Income Taxes (Topic 740) - Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists.” This ASU requires that companies net their unrecognized tax benefits against all same-jurisdiction net operating losses or tax credits carryforwards that would be used to settle the position with a tax authority. This standard is effective for all entities that have unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists for fiscal years, and interim periods beginning after December 15, 2013. The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements.
