Net Income Per Common Share

Net Income Per Common Share [Abstract]

Net Income Per Common Share

2. 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 period presented as well as the computation of basic and diluted net income per common share:


	Three Months Ended				Six Months Ended
	October 1, 2011		October 2, 2010		October 1, 2011		October 2, 2010

Effect of dilution due to employee stock options		443,530		365,470		459,187		366,487
Denominator for diluted net income per common share — weighted-average shares outstanding		22,297,428		21,991,668		22,303,013		21,984,410

Diluted net income per common share	$	0.52	$	0.39	$	1.00	$	0.80

Basic weighted-average common shares do not include 81,467 and 135,480 unvested restricted stock shares at October 1, 2011 and October 2, 2010, respectively.

At October 1, 2011, 18,000 employee stock options have been excluded from the calculation of diluted earnings per share, as the inclusion of these shares would be anti-dilutive. 528,700 such options were excluded at October 2, 2010.

- Definition

The entire disclosure for cash and cash equivalent footnotes, which may include the types of deposits and money market instruments, applicable carrying amounts, restricted amounts and compensating balance arrangements. Cash and equivalents include: (1) currency on hand (2) demand deposits with banks or financial institutions (3) other kinds of accounts that have the general characteristics of demand deposits (4) short-term, highly liquid investments that are both readily convertible to known amounts of cash and so near their maturity that they present insignificant risk of changes in value because of changes in interest rates. Generally, only investments maturing within three months from the date of acquisition qualify.

Debt [Abstract]

Debt

8. Debt

The balances payable under all borrowing facilities are as follows:


	October 1, 2011		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
Notes payable		1,134		1,296
Total debt		1,134		31,296
Less: current portion		1,134		30,546
Long-term debt	$	—	$	750

On November 30, 2010, the Company 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, measured at the end of each quarter. As of October 1, 2011, the Company's margin is 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 October 1, 2011, 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 October 1, 2011, 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 $4,436, 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 October 1, 2011, there were no borrowings under the Swiss Credit Facility.

- 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.

Income Taxes	6 Months Ended
Income Taxes	Oct. 01, 2011
Income Taxes [Abstract]
Income Taxes	9. Income Taxes 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, 2004. The effective income tax rates for the three and six month periods ended October 1, 2011 and October 2, 2010 were 35.0% and 34.4% and 34.7% and 33.1%, respectively. The effective income tax rates for the three and six month periods ended October 1, 2011 and October 2, 2010 are different from the U.S. statutory rates due to a special manufacturing deduction in the U.S. and foreign income taxed at lower rates which decrease the rate, and state income taxes and an officers' compensation adjustment which increase the rate. The effective income tax rate for the six month period ended October 2, 2010 of 33.1% includes the reversal of unrecognized tax benefits associated with the conclusion of the Company's IRS audit. A U.S. federal income tax examination by the Internal Revenue Service for the years ended March 31, 2007 and March 31, 2008 was completed during fiscal 2011. The effective income tax rate for the six month period ended October 2, 2010 without this discrete item would have been 35.2%. The Company maintains reserves for certain other unrecognized tax benefits of $2,525 related to this matter based on management's judgment that the related tax positions have not yet been effectively settled. Management expects such tax positions to be settled by the end of the Company's fiscal year ending March 31, 2012 or the end of the Company's fiscal quarter ending June 30, 2012.

Segment Information

10. Segment Information

The Company has four reportable business segments engaged in the manufacture and sale of the following:

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 minor 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.

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.

Derivative Instruments	6 Months Ended
Derivative Instruments	Oct. 01, 2011
Derivative Instruments [Abstract]
Derivative Instruments	11. 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 October 1, 2011, 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 $4,255 at October 1, 2011 and $850 at April 2, 2011. These financial instruments have maturities that extend to October 2012. Unrealized gains related to derivative financial instruments were $18 and $13 at October 1, 2011 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.

- Definition

Net of tax effect change in accumulated gains and losses from derivative instruments designated and qualifying as the effective portion of cash flow hedges after taxes. A cash flow hedge is a hedge of the exposure to variability in the cash flows of a recognized asset or liability or a forecasted transaction that is attributable to a particular risk. The change includes an entity's share of an equity investee's increase or decrease in deferred hedging gains or losses. While for technical reasons this element has no balance attribute, the default assumption is a credit balance consistent with its label.
