Net Income Per Common Share

Earnings Per 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				Nine Months Ended
	December 28, 2013		December 29, 2012		December 28, 2013		December 29, 2012

Effect of dilution due to employee stock options		402,841		323,845		364,705		437,312
Denominator for diluted net income per common share — weighted-average shares outstanding		23,311,397		22,862,347		23,205,716		22,724,286

Basic net income per common share	$	0.56	$	0.54	$	1.84	$	2.05

Diluted net income per common share	$	0.55	$	0.53	$	1.81	$	2.01

At December 28, 2013, 193,500 employee stock options and no restricted shares have been excluded from the calculation of diluted earnings per share. At December 29, 2012, 209,500 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 unvested restricted stock shares would be anti-dilutive.

Cash and Cash Equivalents, at Carrying Value [Abstract]

Cash and Cash Equivalents

3. 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.

Short-term investments are comprised of equity securities and are measured at fair value by using quoted prices in active markets and are classified as Level 1 of the valuation hierarchy.

- 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 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 December 28, 2013 was 8,835 CHF, or $9,915.

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 Roller Bearing Company of America, Inc. (“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 December 28, 2013, 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 December 28, 2013, the Company was in compliance with all such covenants.

Approximately $4,348 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 December 28, 2013, RBCA had the ability to borrow up to an additional $145,652 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 CHF, or $4,489, 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 December 28, 2013, there were no borrowings under the Swiss Credit Facility.

The Company files income tax returns in the U.S. federal jurisdiction, 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 April 2, 2005. The Company is no longer subject to U.S. federal corporate income tax examination by the Internal Revenue Service for fiscal years ending before March 31, 2012. A U.S. federal corporate income tax examination by the Internal Revenue Service for the fiscal year ended April 2, 2011 was deemed effectively settled in the Company’s first quarter of the fiscal year ended March 29, 2014 and the statute of limitations expired for the Company’s fiscal year ended April 3, 2010 in the Company’s third quarter of the fiscal year ended March 29, 2014.

The effective income tax rates for the three month periods ended December 28, 2013 and December 29, 2012, were 34.0% and 35.1%. The effective income tax rates for the nine month periods ended December 28, 2013 and December 29, 2012 were 33.2% and 29.2%, 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 which increases the rate.

The effective income tax rate for the three month period ended December 28, 2013 of 34.0% includes discrete items of $56 which are substantially comprised of the reversal of unrecognized tax benefits associated with the expiration of statutes of limitations as well as the recognition of interest on unrecognized tax positions. The effective income tax rate for the three month period ended December 29, 2012 of 35.1% includes discrete items of $105 which are substantially comprised of the reversal of unrecognized tax benefits associated with the expiration of statutes of limitations along with the recognition of interest on unrecognized tax positions. The effective income tax rate without discrete items for the three month periods ended December 28, 2013 and December 29, 2012 would have been 34.3% and 35.6%, respectively. 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 approximately $393.

Segment Reporting [Abstract]

Reportable Segments

8. 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.

Restructuring and Related Activities [Abstract]

Restructuring of Operations

9. Restructuring of Operations

In the fourth quarter of fiscal 2013, the Company reached a decision to consolidate and restructure its large bearing manufacturing facilities and capacity. This decision was based on the Company’s intent to better align manufacturing abilities and product development. The consolidation of the Texas facility into the South Carolina operation will strengthen and bring critical engineering and manufacturing mass to the large bearing product line. The consolidation and restructuring includes: (1) consolidation of the machinery and equipment from Texas into South Carolina resulting in a certain portion being impaired and the remaining portion used to service the large bearing product offering; (2) sale or lease of the Texas building; and (3) a reduction in workforce in Texas due to the realignment. The majority of the expense associated with the consolidation and restructuring was incurred in fiscal 2013 with continued effort to sell the equipment and sell or lease the building to be completed in fiscal 2014. As a result, the Company recorded a pre-tax charge of $6,738 under operating expenses in the Other, net category of the income statement for fiscal 2013 associated with this consolidation and restructuring. This charge included $466 in employee related costs, $100 in moving and relocation costs and $6,172 impairment to fair value of certain equipment used in the manufacturing of large bearings. The Company determined that the market approach was the most appropriate method to estimate the fair value for the equipment and building using comparable sales data and actual quotes from potential buyers in the market place. These assets continue to be classified in fixed assets on the December 28, 2013 balance sheet. This analysis of fair value of assets resulted in a $6,172 impairment loss in fiscal 2013 and is attributable to the Ball Bearings segment in which all of these assets reside. The Company incurred period costs of $1,720 in the first nine months of fiscal 2014, bringing the total incurred due to the restructuring and consolidation to $8,458. The Company will continue to incur operational costs such as depreciation, utilities and maintenance until the building is sold or leased.

Acquisitions

10. Acquisitions

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 the last calendar year 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). 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 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 $766. 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 last calendar year 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 ($5,538), intangible assets ($3,904), other non-current assets ($10), other current liabilities ($2,086), and noncurrent liabilities ($1,974). 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, Roller Bearing Company of America, Inc. and RBC Southwest Products, Inc. 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. Proforma net sales and net income inclusive of WPA are not materially different from the amounts reported in the accompanying consolidated statements of operations.
