Organization, Consolidation and Presentation of Financial Statements [Abstract]

Organization and Business

The consolidated financial statements included herein have been prepared by RBC Bearings Incorporated, a Delaware corporation (collectively with its subsidiaries, the “Company”), without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. The April 2, 2016 fiscal year end balance sheet data have been derived from the Company’s audited financial statements, but do not include all disclosures required by generally accepted accounting principles in the United States. The interim financial statements included with this report have been prepared on a consistent basis with the Company’s audited financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended April 2, 2016.

These statements reflect all adjustments, accruals and estimates consisting only of items of a normal recurring nature, which are, in the opinion of management, necessary for the fair presentation of the consolidated financial condition and consolidated results of operations for the interim periods presented. These financial statements should be read in conjunction with the Company’s audited financial statements and notes thereto included in the Annual Report on Form 10-K.

The results of operations for the three month period ended December 31, 2016 are not necessarily indicative of the operating results for the entire fiscal year ending April 1, 2017. The three month periods ended December 31, 2016 and December 26, 2015 each include 13 weeks. The amounts shown are in thousands, unless otherwise indicated.

Critical Accounting Policies

Revenue Recognition. In accordance with SEC Staff Accounting Bulletin 101 "Revenue Recognition in Financial Statements as amended by Staff Accounting Bulletin 104,” we recognize revenues principally from the sale of products at the point of passage of title, which is at the time of shipment, except for certain customers for which it occurs when the products reach their destination.

We also recognize revenue on a Ship-In-Place basis for two customers who have required that we hold the product after final production is complete. In this case, a written agreement has been executed (at the customer’s request) whereby the customer accepts the risk of loss for product that is invoiced under the Ship-In-Place arrangement. For each transaction for which revenue is recognized under a Ship-In-Place arrangement, all final manufacturing inspections have been completed and customer acceptance has been obtained. In the three months ended December 31, 2016, 2.9% of the Company’s total net sales was recognized under Ship-In-Place transactions.

Adoption of Recent Accounting Pronouncements

In October 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards update (“ASU") No. 2016-16, “Income Taxes”, in an effort to improve the accounting for the income tax consequences of intra-equity transfers of assets other than inventory. Current GAAP prohibits the recognition of current and deferred income taxes for an intra-entity asset transfer until the asset has been sold to an outside party. This ASU establishes the requirement that an entity recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. This ASU is effective for public companies for the financial statements issued for annual periods beginning after December 15, 2017 and interim periods within those annual periods. Earlier application is permitted as of the beginning of an interim or annual reporting period, with any adjustments reflected as of the beginning of the fiscal year of adoption. 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 August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows”, which addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. This ASU is effective for public companies for the financial statements issued for annual periods beginning after December 15, 2017 and interim periods within those annual periods. Earlier application is permitted as of the beginning of an interim or annual reporting period, with any adjustments reflected as of the beginning of the fiscal year of adoption. The Company has not determined the effect that the adoption of the pronouncement may have on its statements of cash flows.

In March 2016, the FASB issued ASU No. 2016-09, "Improvements to Employee Share-Based Payment Accounting" which amends ASC Topic 718, Compensation - Stock Compensation. This ASU includes provisions intended to simplify various aspects related to how share-based payments are accounted for and presented in the financial statements. This ASU is effective for public companies for the financial statements issued for annual periods beginning after December 15, 2016 and interim periods within those annual periods. Earlier application is permitted as of the beginning of an interim or annual reporting period, with any adjustments reflected as of the beginning of the fiscal year of adoption. 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 March 2016, the FASB issued ASU No. 2016-08, “Revenue from Contracts with Customers (Topic 606) – Principal versus Agent Considerations (Reporting Revenue Gross versus Net),” which amends the principal-versus-agent implementation guidance in ASU No. 2014-09 (Topic 606), “Revenue from Contracts with Customers”, issued by the FASB in May 2014. ASU No. 2016-08 clarifies the principal-versus-agent guidance in Topic 606 and requires an entity to determine whether the nature of its promise to provide goods or services to a customer is performed in a principal or agent capacity and to recognize revenue in a gross or net manner based on its principal/agent designation. ASU 2014-09 is a comprehensive new revenue recognition standard that will supersede nearly all existing revenue recognition guidance under U.S. GAAP. This update requires the Company to recognize revenue at amounts that reflect the consideration to which the Company expects to be entitled in exchange for those goods or services at the time of transfer. In doing so, the Company will need to use more judgement and make more estimates than under today’s guidance, such estimates include identifying performance obligations in the contracts, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. The Company can either apply a full retrospective adoption or a modified retrospective adoption. This ASU is effective for annual reporting periods beginning after December 15, 2017 and interim periods therein. 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 February 2016, the FASB issued ASU No. 2016-02, “Leases.” The core principal of ASU 2016-02 is that an entity should recognize on its balance sheet assets and liabilities arising from a lease. In accordance with that principle, ASU 2016-02 requires that a lessee recognize a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying leased asset for the lease term. The recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee will depend on the lease classification as a finance or operating lease. This new accounting guidance is effective for public companies for fiscal years beginning after December 15, 2018 under a modified retrospective approach and early adoption is permitted. The Company is currently evaluating the impact this adoption will have on its consolidated financial statements.

In July 2015, the FASB issued ASU No. 2015-11, “Simplifying the Measurement of Inventory.” This update requires the company to measure inventory using the lower of cost and net realizable value. Net realizable value is defined as the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. This ASU applies to companies measuring inventory using methods other than the last-in, first-out (LIFO) and retail inventory methods, including but not limited to the first-in, first-out (FIFO) or average costing methods. 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 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.

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

Effect of dilution due to employee stock awards		231,859		271,614		261,404		310,379
Denominator for diluted net income per common share — weighted-average shares outstanding		23,813,780		23,492,321		23,719,121		23,508,348

Basic net income per common share	$	0.54	$	0.73	$	2.09	$	1.94

Diluted net income per common share	$	0.54	$	0.73	$	2.07	$	1.91

At December 31, 2016, 449,500 employee stock options and 81,650 restricted shares have been excluded from the calculation of diluted earnings per share. At December 26, 2015, 444,250 employee stock options and 65,600 restricted shares have been excluded from the calculation of diluted earnings per share. The inclusion of these employee stock options and unvested restricted shares would be anti-dilutive.

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, if any, 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.

The Credit Facility

In connection with the Sargent Aerospace & Defense (“Sargent”) acquisition on April 24, 2015, the Company entered into 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 $200,000 Term Loan and (b) a $350,000 Revolver and together with the Term Loan (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 0.5% for base rate loans and 1.5% for LIBOR rate loans. As of December 31, 2016, there was $107,500 outstanding under the Revolver and $185,000 outstanding under the Term Loan, offset by $4,748 in debt issuance costs (original amount was $7,122).

The 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 3.50 to 1; and (2) a consolidated interest coverage ratio not to exceed 2.75 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 31 2016, the Company was in compliance with all such covenants.

The Company’s obligations under the Credit Agreement are secured as well as providing for a pledge of substantially all of the Company’s and RBCA’s assets. The Company and certain of its subsidiaries have also entered into a Guarantee to guarantee RBCA’s obligations under the Credit Agreement.

Approximately $3,690 of the Revolver is being utilized to provide letters of credit to secure RBCA’s obligations relating to certain insurance programs. As of December 31, 2016, RBCA has the ability to borrow up to an additional $238,810 under the Revolver.

Other Notes Payable

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 31, 2016 was 7,324 CHF, or $7,191.

Income Tax Disclosure [Abstract]

Income Taxes

7. Income Taxes

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 29, 2014. A U.S. federal corporate income tax examination by the Internal Revenue Service for the fiscal year ended March 30, 2013 was deemed effectively settled in the Company’s first quarter of fiscal 2016.

The effective income tax rates for the three month periods ended December 31, 2016 and December 26, 2015, were 31.5% and 31.5%. 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 U.S. manufacturing deduction, the U.S. credit for increasing research activities, 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 31, 2016 of 31.5% includes immaterial discrete items of $56. The effective income tax rate without discrete items for the three month period ended December 31, 2016 would have been 31.8%. The effective income tax rate for the three month period ended December 26, 2015 of 31.5% includes immaterial discrete items of $154. The effective income tax rate without discrete items for the three month period ended December 26, 2015 would have been 32.1%. 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 $314.

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.

The Company has four reportable business segments; Plain Bearings, Roller Bearings, Ball Bearings and Engineered Products, which are described below.

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. The bearings and rings businesses of Sargent are included here.

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.

Engineered Products. Engineered Products consists of highly engineered hydraulics, fasteners, collets and precision components used in aerospace, marine and industrial applications. The hydraulics, fasteners and precision components businesses of Sargent are included here.

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.

Acquisitions

9. Acquisitions

On April 24, 2015, the Company acquired Sargent from Dover Corporation for $500,000 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 engineered components under leading brands including Kahr Bearing, Airtomic, Sonic Industries, Sargent Controls and Sargent Aerospace & Defense. The Company acquired Sargent because management believes it provides complementary products and channels, and expands and enhances the Company’s product portfolio and engineering technologies. The bearings and rings businesses are included in the Plain Bearings segment. The hydraulics, fasteners and precision components businesses are included in the Engineered Products segment.

The acquisition of Sargent was accounted for as a purchase in accordance with FASB Accounting Standards Codification (“ASC”) Topic 805, Business Combinations. Assets acquired and liabilities assumed were recorded at their fair values as of the acquisition date. The fair values of identifiable intangible assets, which were primarily customer relationships, product approvals, trade names, and patents and trademarks, were based on valuations using the income approach. The excess of the purchase price over the estimated fair values of tangible assets, identifiable intangible assets and assumed liabilities was recorded as goodwill. The goodwill is attributable to expected synergies and expected growth opportunities. The purchase price allocation resulted in goodwill of $224,715. The Company estimates a majority of goodwill will be deductible for United States income tax purposes.

The purchase price allocation for Sargent was as follows:

	As of April 24, 2015
Current assets	$	3,086
Trade receivables		24,100
Inventories		49,245
Property, plant and equipment		39,907
Intangible assets		202,500
Goodwill		224,715
Total assets acquired		543,553
Accounts payable		14,900
Liabilities assumed		28,653
Net assets acquired	$	500,000

The valuation of the net assets acquired of $500,000 was classified as Level 3 in the valuation hierarchy. Level 3 inputs represent unobservable inputs for the asset or liability.

The components of intangible assets included as part of the Sargent acquisition was as follows:

	Weighted Average Amortization Period (Years)		Gross Value
Amortizable intangible assets
Customer relationships		25	$	99,800
Product approvals		25		50,500
Trademarks and tradenames		10		18,000
				168,300
Non-amortizable intangible assets
Repair station certifications		-		34,200
Intangible assets			$	202,500

Included in the Company’s results of operations for the three and nine months ended December 31, 2016 are revenues related to the Sargent acquisition of $44,837 and $138,121, respectively. Also, included for the three and nine months ended December 31, 2016 is net income of $5,671 and $14,254, respectively. Included in the Company’s results of operations for the three and nine months ended December 26, 2015 are revenues related to the Sargent acquisition of $43,862 and $123,371, respectively.

Restructuring of Operations

10. Integration and Restructuring of Industrial Operations

In the third quarter of fiscal 2017, the Company reached a decision to integrate and restructure its industrial manufacturing operation in South Carolina. The Company will exit a few smaller product offerings and consolidate two manufacturing facilities into one. These restructuring efforts will better align our manufacturing capacity and market focus. As a result, the Company recorded a charge of $7,060 associated with the restructuring in the third quarter of fiscal 2017 attributable to the Roller Bearings segment. The $7,060 charge includes $3,215 of inventory rationalization costs, $261 in impairment of intangibles, $2,402 loss on fixed assets disposals, and $1,182 exit obligation associated with a building operating lease. 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 $7,060 was offset with a tax benefit of approximately $2,222. The Company determined that the market approach was the most appropriate method to estimate the fair value for the inventory, intangible assets, equipment and building operating lease using comparable sales data and actual quotes from potential buyers in the market place.
