Net Income Per Common Share

Earnings Per Share [Abstract]

Net Income Per Common Share

1. 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
	June 30, 2012		July 2, 2011

Net income	$	17,164	$	10,712

Denominator for basic net income per common share—weighted-average shares outstanding		22,030,272		21,833,754
Effect of dilution due to employee stock options		566,132		474,844
Denominator for diluted net income per common share — weighted-average shares outstanding		22,596,404		22,308,598

Basic net income per common share	$	0.78	$	0.49

Diluted net income per common share	$	0.76	$	0.48

At June 30, 2012, 200,900 employee stock options and 700 restricted shares have been excluded from the calculation of diluted earnings per share. At July 2, 2011, 8,000 employee stock options and no 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.

2. 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.

- 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.

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 June 30, 2012, 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 June 30, 2012, the Company was in compliance with all such covenants.

Approximately $5,545 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 June 30, 2012, RBCA had the ability to borrow up to an additional $144,455 under the JP Morgan Credit Agreement.

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 $4,187, 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 June 30, 2012, 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 [Abstract]

Income Taxes

6. 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, 2002. The Company is no longer subject to U.S. federal tax examination by the Internal Revenue Service for years ending before March 31, 2006. A U.S. federal tax examination by the Internal Revenue Service for the years ended March 31, 2007 and March 31, 2008 was substantially completed during fiscal 2011.

The effective income tax rates for the three month periods ended June 30, 2012 and July 2, 2011 were 31.6% and 34.5%, respectively. In addition to discrete items, the effective income tax rates for these periods 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 three month period ended June 30, 2012 of 31.6% includes the reversal of unrecognized tax benefits associated with the conclusion of state income tax audits of $862. The effective income tax rate without these discrete items would have been 35.0%. The Company believes it is reasonably possible that some of its unrecognized tax positions may be effectively settled within the next twelve months due to the closing of audits and the statute of limitations expiring in varying jurisdictions. The decrease, pertaining primarily to credits and state tax, is estimated to be between $5,900 and $6,300.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Segment Information [Abstract]

Segment Information

7. 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.

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 and Hedging Activities Disclosure [Abstract]

Derivative Instruments

8. 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 June 30, 2012, the expected net impact of existing gains or losses to be reclassified from AOCI into earnings in the next twelve months is not material.

Notional amounts of the derivative financial instruments qualifying and designated as hedges were $419 at June 30, 2012 and $1,401 at March 31, 2012. These financial instruments have maturities that extend to October 2012. Unrealized losses (gains) related to derivative financial instruments were immaterial at June 30, 2012 and July 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.
