Significant Accounting Policies

2. Significant Accounting Policies

The Company’s significant accounting policies are detailed in “Note 2 - Summary of Significant Accounting Policies” of our Annual Report on Form 10-K for the year ended March 31, 2018. Significant changes to our accounting policies as a result of adopting new accounting standards are discussed below.

Recent Accounting Standards Adopted

In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers (Topic 606). The Company adopted this standard on April 1, 2018. This new guidance provides a five-step model to determine when and how revenue is recognized, and requires an entity to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.

A contract with a customer exists when there is commitment and approval from both parties involved, the rights of the parties are identified, payment terms are defined, the contract has commercial substance and collectability of consideration is probable. The Company has determined that the contract with the customer is established when the customer purchase order is accepted or acknowledged. Long-term agreements (LTAs) are used by the Company and certain of its customers to reduce their supply uncertainty for a period of time, typically multiple years. While these LTAs define commercial terms including pricing, termination rights and other contractual requirements, they do not represent the contract with the customer for revenue recognition purposes.

When the Company accepts or acknowledges the customer purchase order, the type of good or service is defined on a line-by-line basis. Individual performance obligations are established by virtue of the individual line items identified on the sales order acknowledgment at the time of issuance. The majority of the Company’s revenue relates to the sale of goods and contains a single performance obligation for each distinct good. The remainder of the Company’s revenue from customers is generated from services performed. These services include repair and refurbishment work performed on customer-controlled assets as well as design and test work. The performance obligations for these services are also identified on the sales order acknowledgement at the time of issuance on a line-by-line basis.

Transaction price reflects the amount of consideration that the Company expects to be entitled to in exchange for transferred goods or services. A contract’s transaction price is allocated to each distinct performance obligation and revenue is recognized as the performance obligation is satisfied. For the majority of our contracts, the Company may provide distinct goods or services, in which case we separate the contract into more than one performance obligation (i.e., a good or service is individually listed in a contract or sold individually to a customer). The Company generally sells products and services with observable standalone selling prices.

The performance obligations for the majority of RBC’s product sales are satisfied at the point in time in which the products are shipped, consistent with the pattern of revenue recognition under the previous accounting standard. The Company has determined that the customer obtains control upon shipment of the product based on the shipping terms (either when it ships from RBC’s dock or when the product arrives at the customer’s dock) and recognizes revenue accordingly. Once a product has shipped, the customer is able to direct the use of, and obtain substantially all of the remaining benefits from, the asset. Approximately 94% of the Company’s revenue was recognized in this manner based on sales for the three and nine-month periods ended December 29, 2018, respectively.

The Company has determined performance obligations are satisfied over time for customer contracts where RBC provides services to customers and also for a limited number of product sales. RBC has determined revenue recognition over time is appropriate for our service revenue contracts as they create or enhance an asset that the customer controls throughout the duration of the contract. Approximately 6% of the Company’s revenue was recognized in this manner based on sales for the three and nine-month periods ended December 29, 2018, respectively. Revenue recognition over time is appropriate for customer contracts with product sales in which the product sold has no alternative use to RBC without significant economic loss and an enforceable right to payment exists, including a normal profit margin from the customer, in the event of contract termination. These types of contracts comprised less than 1% of total sales for both the three and nine-month periods ended December 29, 2018, respectively. For both of these types of contracts, revenue is recognized over time based on the extent of progress towards completion of the performance obligation. The Company utilizes the cost-to-cost measure of progress for over-time revenue recognition contracts as we believe this measure best depicts the transfer of control to the customer, which occurs as we incur costs on contracts. Revenues, including profits, are recorded proportionally as costs are incurred. Costs to fulfill include labor, materials, subcontractors’ costs, and other direct and indirect costs.

Contract costs are the incremental costs of obtaining and fulfilling a contract (i.e., costs that would not have been incurred if the contract had not been obtained) to provide goods and services to customers. Contract costs largely consist of design and development costs for molds, dies and other tools that RBC will own and that will be used in producing the products under the supply arrangements. These contract costs are amortized to expense on a systematic and rational basis over a period consistent with the transfer to the customer of the goods or services to which the asset relates. Costs incurred to obtain a contract are primarily related to sales commissions and are expensed as incurred as they are generally not tied to specific customer contracts. These costs are included within selling, general and administrative costs on the consolidated statements of operations.

In certain contracts, the Company facilitates shipping and handling activities after control has transferred to the customer. The Company has elected to record all shipping and handling activities as costs to fulfill a contract. In situations where the shipping and handling costs have not been incurred at the time revenue is recognized, the estimated shipping and handling costs are accrued.

In June 2018, the FASB issued ASU No. 2018-07, Compensation – Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting, as part of its simplification initiative. This update will expand the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. This ASU also clarifies that Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. This update is effective for public companies for fiscal years beginning after December 15, 2018, including interim periods within that year. Early adoption is permitted, but no earlier than a company’s adoption of Topic 606. The Company has early adopted this ASU in the second quarter of fiscal 2019 and it did not have a material impact on the Company’s consolidated financial statements.

In May 2017, the FASB issued ASU No. 2017-09, Compensation – Stock Compensation (Topic 718): Scope of Modification Accounting, in an effort to reduce diversity in practice as it relates to applying modification accounting for changes to the terms and conditions of share-based payment awards. This ASU was effective for public companies for financial statements issued for annual periods beginning after December 15, 2017, including interim periods within those annual periods. Early adoption was permitted. The Company adopted this ASU on April 1, 2018 and it did not have a material impact on the Company’s consolidated financial statements.

In March 2017, the FASB issued ASU No. 2017-07, Compensation – Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, in an effort to improve the presentation of these costs within the income statement. Prior to this ASU, all components of both net periodic pension cost and net periodic postretirement cost were included within the same line items as other compensation costs arising from services rendered by pertinent employees during the period on the income statement. This ASU requires entities to include only the service cost component within those line items and all other components are to be included within other non-operating expense. In addition, only the service cost component would be eligible for capitalization when applicable (for example, as a cost of internally manufactured inventory or a self-constructed asset). The amendments in this ASU should be applied retrospectively for the presentation of the service cost component and the other components of net periodic pension cost and net periodic postretirement benefit cost in the income statement and prospectively, on and after the effective date, for the capitalization of the service cost component of net periodic pension cost and net periodic postretirement benefit in assets. This ASU was effective for public companies for the financial statements issued for annual periods beginning after December 15, 2017, including interim periods within those annual periods. A practical expedient allows the Company to use the amount disclosed for net periodic benefit costs for the prior comparative periods as the estimation basis for applying the retrospective presentation requirements. The Company retrospectively adopted the ASU on April 1, 2018 and utilized this practical expedient. The adoption of this ASU resulted in the reclassification of $159 of net periodic benefit cost from compensation costs ($107 included within cost of sales and $52 within other, net) to other non-operating expense on the consolidated statement of operations for the three-month period ended December 30, 2017 and $477 of net periodic benefit cost from compensation costs ($321 included within cost of sales and $156 within other, net) to other non-operating expense on the consolidated statement of operations for the nine-month period ended December 30, 2017.

In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory, in an effort to improve the accounting for the income tax consequences of intra-entity transfers of assets other than inventory. Previous GAAP prohibited 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 established 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 was 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 adoption was 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 adopted this ASU on April 1, 2018 and it did not have a material impact on the Company’s consolidated financial statements.

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. This ASU was 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 adoption was 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 adopted this ASU on April 1, 2018 and it did not have a material impact on the Company’s consolidated financial statements.

Recent Accounting Standards Yet to Be Adopted

In February 2018, the FASB issued ASU No. 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income which allows companies to reclassify stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017 (TCJA or “the Act”) from accumulated other comprehensive income to retained earnings. These stranded tax effects refer to the tax amounts included in accumulated other comprehensive income at the previous 35% U.S. corporate statutory federal tax rate, for which the related deferred tax asset or liability was remeasured to the new 21% U.S. corporate statutory federal tax rate in the period of the TCJA’s enactment. The new standard is effective for fiscal years beginning after December 15, 2018, with early adoption permitted, and can be applied either in the period of adoption or retrospectively to each period impacted by the TCJA. The Company is evaluating the effect of adopting this new accounting guidance, but does not expect adoption will have a material impact on the Company’s financial position as the adjustment will be between accumulated other comprehensive income and retained earnings, both of which are components of total stockholders’ equity.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The objective of this standard update is to simplify the subsequent measurement of goodwill, eliminating Step 2 from the goodwill impairment test. Under this ASU, an entity should perform its annual goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity would recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value, assuming the loss recognized does not exceed the total amount of goodwill for the reporting unit. The standard update is effective for fiscal years beginning after December 15, 2019. Early adoption is permitted. The adoption of this ASU is not expected to have a material impact on the Company’s consolidated financial statements.

In September 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments, which changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The new guidance will replace the current incurred loss approach with an expected loss model. The new expected credit loss impairment model will apply to most financial assets measured at amortized cost and certain other instruments, including trade and other receivables, loans, held-to-maturity debt instruments, net investments in leases, loan commitments and standby letters of credit. Upon initial recognition of the exposure, the expected credit loss model requires entities to estimate the credit losses expected over the life of an exposure (or pool of exposures). The estimate of expected credit losses should consider historical information, current information and reasonable and supportable forecasts, including estimates of prepayments. Financial instruments with similar risk characteristics should be grouped together when estimating expected credit losses. ASU 2016-13 does not prescribe a specific method to make the estimate, so its application will require significant judgment. This ASU is effective for public companies in fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company is currently evaluating the effect that the adoption of this ASU will have on the Company’s consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The core principle of this ASU 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 and early adoption is permitted. The Company has formed an implementation team to assess its leases as defined under the new accounting standard and anticipates making certain changes to existing processes, policies and systems during implementation. The Company anticipates the amended guidance will have a material impact on its assets and liabilities due to the addition of right-of-use assets and lease liabilities to the balance sheet; however, it does not expect the amended guidance to have a material impact on its cash flows, results of operations or debt covenant compliance.

Other new pronouncements issued but not effective until after March 30, 2019 are not expected to have a material impact on our financial position, results of operations or liquidity.

Adoption Method and Impact

The Company adopted ASC 606 using the modified retrospective method and applied the related provisions to all open contracts. The Company recognized the cumulative effect of initially applying the new revenue standard as an adjustment to the opening balance of retained earnings. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. As a result of adoption, the Company recognized a $277 decrease to retained earnings at the beginning of the 2019 fiscal year for the cumulative effect of adoption of this standard, representing the impact to prior results had the over-time revenue recognition model been applied to service contracts. Contract assets of $1,323 and contract liabilities of $754 were recorded, along with an $847 reduction to work-in-process inventory as a result of the ASC 606 adoption using the modified retrospective method.

In addition, as a result of the accounting changes resulting from this new accounting standard, sales, operating income and net income for the three-month period ended December 29, 2018 increased by $1,132, $615 and $523, respectively. For the nine-month period ended December 29, 2018, sales, operating income and net income increased by $2,002, $1,075 and $897, respectively. Basic and diluted net income per common share each increased by $0.02 and $0.04 for the three and nine-month periods ended December 29, 2018, respectively, as revenue from service contracts was accelerated into these periods as a result of the change to an over-time revenue recognition model. On the consolidated balance sheet, work-in-process inventory was $1,404 lower at December 29, 2018 than it would have been under the previous accounting guidance. In addition, prepaids and other current assets, accrued expenses and other current liabilities, and retained earnings increased by $2,449, $313 and $620, respectively. The changes in other current assets and accrued expenses were directly related to the activity within the customer contract assets and liabilities.

Disaggregation of Revenue

The Company operates in four business segments with similar economic characteristics, including nature of the products and production processes, distribution patterns and classes of customers. Revenue is disaggregated within these business segments by our two principal end markets: aerospace and industrial. Comparative information of the Company’s overall revenues for the three and nine-month periods ended December 29, 2018 and December 30, 2017 are as follows:

In addition to disaggregating revenue by segment and principal end markets, the Company believes information about the timing of transfer of goods or services, type of customer and distinguishing service revenue from product sales is also relevant. Refer to Note 2 – “Significant Accounting Policies” for further details.

Remaining Performance Obligations

Remaining performance obligations represent the transaction price of orders meeting the definition of a contract in the new revenue standard for which work has not been performed or has been partially performed and excludes unexercised contract options. The duration of the majority of our contracts, as defined by ASC 606, is less than one year. The Company has elected to apply the practical expedient, which allows companies to exclude remaining performance obligations with an original expected duration of one year or less. Performance obligations having a duration of more than one year are concentrated in contracts for certain products and services provided to the U.S. government or its contractors. The aggregate amount of the transaction price allocated to remaining performance obligations for such contracts with a duration of more than one year was approximately $217,562 at December 29, 2018. The Company expects to recognize revenue on approximately 67% and 94% of the remaining performance obligations over the next 12 and 24 months, respectively, with the remainder recognized thereafter.

Contract Balances

The timing of revenue recognition, invoicing and cash collections affect accounts receivable, unbilled receivables (contract assets) and customer advances and deposits (contract liabilities) on the consolidated balance sheets.

Contract Assets (Unbilled Receivables) - Pursuant to the over-time revenue recognition model, revenue may be recognized prior to the customer being invoiced. An unbilled receivable is recorded to reflect revenue that is recognized when (1) the cost-to-cost method is applied and (2) such revenue exceeds the amount invoiced to the customer.

Contract Liabilities (Deferred Revenue) - The Company may receive a customer advance or deposit, or have an unconditional right to receive a customer advance, prior to revenue being recognized. Since the performance obligations related to such advances may not have been satisfied, a contract liability is established. Contract liabilities are included within accrued expenses and other current liabilities or other non-current liabilities on the consolidated balance sheets until the respective revenue is recognized. Advance payments are not considered a significant financing component as the timing of the transfer of the related goods or services is at the discretion of the customer.

These assets and liabilities are reported on the consolidated balance sheet on an individual contract basis at the end of each reporting period. As of December 29, 2018 and March 31, 2018, accounts receivable with customers, net, were $116,673 and $116,890, respectively. The tables below represent a roll-forward of contract assets and contract liabilities for the nine-month period ended December 29, 2018:

4. 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:

$6,691 of goodwill was included in the net loss on the sale of the Miami division during the third quarter of fiscal 2019. Miami was previously included within the Engineered Products (“EP”) Reporting Unit (“RU”). When a business within an RU is sold, the Company is required to perform an interim goodwill impairment test on that RU which consists of two steps. First, the Company determines the fair value of the RU and compares it to its carrying amount. Second, if the carrying amount of the RU exceeds its fair value, an impairment loss is recognized for any excess of the carrying amount of the RU’s goodwill over the goodwill’s implied fair value. The Company conducted this interim test over the EP RU as of the date of sale (November 28, 2018) using the same approach used during our most recent annual test (the income approach, also known as the discounted cash flow method). 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 RU in determining the appropriate discount rate to be used. The discount rate utilized for the EP RU for our interim test was 11.0% and 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 terminal growth rate used for our interim test was 2.5%. The Company has determined that, to date, no impairment of goodwill exists and fair value of the EP RU exceeded the carrying value in total by approximately 21.9%. A decrease of 1.0% in our terminal growth rate would not result in impairment of goodwill for the EP RU. An increase of 1.0% in our discount rate would not result in impairment of goodwill for the EP RU. The Company will perform the annual impairment testing during the fourth quarter of fiscal 2019 for all of the Company’s RUs. 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.

Credit Facility

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 Company’s prior credit agreement with JP Morgan. The Credit Agreement provides the Company with a $200,000 term loan (the “Term Loan”) and a $350,000 revolving credit facility (the “Revolver”). The Term Loan and the Revolver (the “Facilities”) expire on April 24, 2020.

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 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 0.00% for base rate loans and 1.00% for LIBOR loans.

On May 31, 2018, the Company paid off the remaining balance of the Term Loan. $987 in unamortized debt issuance costs associated with the Term Loan were written off at the time of payoff and were recorded within other non-operating expense on the consolidated statements of operations.

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 greater than 3.50 to 1; and (2) a consolidated interest coverage ratio of at least 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 Credit Agreement. As of December 29, 2018, the Company was in compliance with all such covenants.

The Company’s domestic subsidiaries are parties to a Guarantee to guarantee the Company’s obligations under the Credit Agreement. The Company’s obligations under the Credit Agreement and the domestic subsidiaries’ guarantee are secured by a pledge of substantially all of the domestic assets of the Company and its domestic subsidiaries.

Approximately $3,990 of the Revolver is being utilized to provide letters of credit to secure the Company’s obligations relating to certain insurance programs. As of December 29, 2018, $1,201 in unamortized debt issuance costs remain. As of December 29, 2018, the Company has the ability to borrow up to an additional $236,760 under the Revolver.

Other Notes Payable

On October 1, 2012, one of our foreign divisions, Schaublin, purchased the land and building, that 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 29, 2018 was 6,394 CHF, or $6,502.

Income Tax Disclosure [Abstract]

Income Taxes

10. 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 April 2, 2005. The Company is no longer subject to U.S. federal tax examination by the Internal Revenue Service for years ending before March 29, 2015. A U.S. federal tax examination by the Internal Revenue Service for the year ended March 30, 2013 was effectively settled in fiscal 2016.

The effective income tax rates for the three month periods ended December 29, 2018 and December 30, 2017, were 15.0% and 23.9%. The reduction in the effective income tax rate for the three months ended December 29, 2018 as compared with the prior year period reflects the net benefits of the Tax Cut and Jobs Act (“TCJA” or “the Act”), which reduced the U.S. statutory rate from 35% to 21% for tax years beginning in 2018 and made other changes to the U.S. federal income tax laws affecting both domestic and foreign income. The reduction in the effective income tax rate includes a benefit associated with the sale of the Miami division, a tax benefit associated with the decrease in the Company’s unrecognized tax positions related to the statute of limitations expiration, and a benefit associated with share-based compensation. The effective tax rate was also increased by a tax expense associated with withholding tax on a one-time repatriation of cash from the Company’s foreign operations during the three months ended December 29, 2018.

The TCJA was signed into law on December 22, 2017 revising the U.S. corporate income tax. Changes included, but were not limited to, the reduction of the U.S. federal corporate rate from 35% to 21%, the elimination of certain deductions and imposing one-time net charge related to the taxation of undistributed foreign earnings. Also on December 22, 2017, the SEC issued Staff Accounting Bulletin No. 118 (“SAB 118”) to address the application of U.S. GAAP in situations where a registrant does not have the necessary information available, prepared or analyzed in reasonable detail to complete the accounting for certain income tax effects of the Act. SAB 118 allowed companies to record provisional estimates during a measurement period not extending beyond one year from the TCJA enactment date.

For the year ended March 31, 2018 the Company recognized as components of income tax expense $9,166 for the one-time net charge related to the taxation of undistributed foreign earnings and $9,318 tax benefit related to the remeasurement of U.S. deferred tax balances to reflect the new U.S. corporate income tax rate. As of December 22, 2018, we have completed the accounting for all impacts of the TCJA and there have been no changes to previously recorded amounts.

No additional income tax provision has been made on any remaining undistributed foreign earnings not subject to the one-time net charge related to the taxation of unremitted foreign earnings or any additional outside basis difference as these amounts continue to be indefinitely reinvested in foreign operations.

One of the international tax law changes provided for with the TCJA relates to the taxation of a corporation’s global intangible low-taxed income (“GILTI”) for tax years beginning after December 31, 2017. The Company has evaluated this provision of the TCJA and the application of ASC 740, and does not believe that GILTI will have a significant impact.

An additional tax law change provided under the TCJA introduced new rules for the treatment of certain foreign income, including foreign derived intangible income (“FDII”) for tax years beginning after December 31, 2017. The Company has evaluated this provision of the TCJA and believes the FDII results in a favorable impact on the application of ASC 740.

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 (fiscal 2018 only), the U.S. credit for increasing research activities which decrease the rate, and state income taxes which increases the rate.

The effective income tax rate for the three-month period ended December 29, 2018 of 15.0% includes $4,048 of tax benefit associated with the sale of the Miami division. The third quarter provision was also impacted by $1,469 of tax benefit associated with the decrease in the Company’s unrecognized tax positions, pertaining primarily to the statute of limitations expiration of items associated with the consolidation and restructuring of the Company’s U.K. manufacturing facility. The third quarter provision also includes $943 tax expense associated with withholding tax on a one-time repatriation of cash from the Company’s foreign operations and $558 of tax benefits associated with share-based compensation. The effective income tax rate without discrete items for the three-month period ended December 29, 2018 would have been 22.3%. The effective income tax rate for the three-month period ended December 30, 2017 of 23.9% was impacted by one-time adjustments associated with the enactment of the TCJA. Included in these adjustments was an estimated charge of $9,491 associated with the repatriation transition tax and an estimated benefit of $8,708 associated with the revaluation of our deferred tax liabilities. The TCJA also impacted the third quarter provision with a benefit from the lower blended statutory tax rate of 31.5% and by $1,238 of tax benefit associated with share-based compensation. The effective income tax rate without discrete items for the three-month period ended December 30, 2017 would have been 25.3%. 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 in the Company’s unrecognized tax positions, pertaining primarily to credits and state tax, is estimated to be approximately $356.

The effective income tax rate for the nine-month period ended December 29, 2018 of 14.6% includes a benefit of $4,048 million associated with the sale of the Miami division. The effective tax rate was also impacted by $1,510 of tax benefit associated with the decrease of the Company’s unrecognized tax positions, pertaining primarily to the consolidation and restructuring of the Company’s U.K. manufacturing facility. The effective rate was also impacted by $943 of tax expense associated with withholding tax on a one-time repatriation of cash from the Company’s foreign operations and $5,063 associated with share-based compensation. The effective income tax rate without this benefit and other items for the nine-month period ended December 29, 2018 would have been 21.6%. The effective income tax rate for the nine-month period ended December 30, 2017 of 28.0% was impacted by one-time adjustments associated with the enactment of the TCJA. These adjustments were mainly comprised of a charge of $9,491 for the repatriation transition tax and a benefit of $8,708 associated with the revaluation of our deferred tax liabilities. The effective income tax rate also benefited from a lower blended statutory tax rate of 31.5% as a result of the enactment of the TCJA and $3,916 tax benefit associated with share-based compensation. The effective income tax rate without discrete items for the three-month period ended December 30, 2017 would have been 33.0%.

Segment Reporting [Abstract]

Reportable Segments

11. 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 are aggregated as reportable segments as they have similar economic characteristics, including nature of the products and production processes, distribution patterns and classes of customers.

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.

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.

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.

Restructuring and Related Activities [Abstract]

Integration and Restructuring of Operations

12. Integration and Restructuring of Operations

On November 28, 2018, the Company sold its Avborne Accessory Group, Inc. subsidiary (“Miami division”) for a sales price of $22,284, subject to a final working capital adjustment. The Miami division, which is based in Miami, Florida, provides maintenance, repair and overhaul services (“MRO”) for a wide variety of aircraft accessories. As a result of the transaction, the Company recorded an after-tax loss of $12,754 associated with the restructuring in the third quarter of fiscal 2019 attributable to the Engineered Products segment. The $12,754 loss was comprised of $22,284 of proceeds received less transaction costs of $1,690, charges associated with goodwill of $6,691, intangible assets of $20,373 and other net assets of $10,332, partially offset by a $4,048 tax benefit. The pre-tax loss of $16,802 was recognized within other, net within the consolidated statement of operations. Prior to the transaction, the Franklin, IN division, which was previously included within Avborne Accessory Group, Inc., was transferred to a separate subsidiary of the Company named Airtomic LLC.

In the second quarter of fiscal 2018, the Company reached a decision to restructure its manufacturing operation in Montreal, Canada. After completing its obligations, the Company closed its RBC Canada location and consolidated certain residual assets into other locations. As a result, the Company recorded an after-tax charge of $5,577 associated with the restructuring in the second quarter of fiscal 2018 attributable to the Engineered Products segment. The $5,577 charge included a $1,337 impairment of fixed assets and a $5,157 impairment of intangible assets offset by a $917 tax benefit. The impairment charges were recognized within other, net within the consolidated statement of operations. The Company determined that the market approach was the most appropriate method to estimate the fair value of the fixed assets using comparable sales data and actual quotes from potential buyers in the market place. The fixed assets were comprised of land, a building, machinery and equipment. The Company assessed the fair value of the intangible assets in accordance with ASC 360-10, which were comprised of customer relationships, product approvals, tradenames and trademarks. These fair value measurements were classified as Level 3 in the valuation hierarchy. In the third and fourth quarters of fiscal 2018, the Company incurred restructuring charges of $1,091 and $100, respectively, comprised primarily of employee termination costs and building maintenance costs. These costs were recorded within other, net within the consolidated statement of operations and are all attributable to the Engineered Products segment. The impact from restructuring in fiscal 2019 has been immaterial. The total cumulative impact resulting from the restructuring was $6,743 in after-tax charges, all attributable to the Engineered Products segment.

Subsequent Events

13. Subsequent Events

On January 31, 2019, the Company amended the Credit 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. The Credit Agreement as so amended (the “Amended Credit Agreement”) now provides the Company with a $250,000 revolving credit facility (the “New Revolver”). The New Revolver expires on January 31, 2024.

Amounts outstanding under the New Revolver 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 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 0.00% for base rate loans and 0.75% for LIBOR loans.

The Amended Credit Agreement requires the Company to comply with various covenants, including among other things, a financial covenant to maintain a ratio of consolidated net debt to adjusted EBITDA not greater than 3.50 to 1. The Amended 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 Amended Credit Agreement. The Company is currently in compliance with all such covenants.

Significant Accounting Policies (Policies)	Dec. 29, 2018
Accounting Policies [Abstract]
Recent Accounting Standards Adopted	Recent Accounting Standards Adopted In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers (Topic 606). The Company adopted this standard on April 1, 2018. This new guidance provides a five-step model to determine when and how revenue is recognized, and requires an entity to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. A contract with a customer exists when there is commitment and approval from both parties involved, the rights of the parties are identified, payment terms are defined, the contract has commercial substance and collectability of consideration is probable. The Company has determined that the contract with the customer is established when the customer purchase order is accepted or acknowledged. Long-term agreements (LTAs) are used by the Company and certain of its customers to reduce their supply uncertainty for a period of time, typically multiple years. While these LTAs define commercial terms including pricing, termination rights and other contractual requirements, they do not represent the contract with the customer for revenue recognition purposes. When the Company accepts or acknowledges the customer purchase order, the type of good or service is defined on a line-by-line basis. Individual performance obligations are established by virtue of the individual line items identified on the sales order acknowledgment at the time of issuance. The majority of the Company’s revenue relates to the sale of goods and contains a single performance obligation for each distinct good. The remainder of the Company’s revenue from customers is generated from services performed. These services include repair and refurbishment work performed on customer-controlled assets as well as design and test work. The performance obligations for these services are also identified on the sales order acknowledgement at the time of issuance on a line-by-line basis. Transaction price reflects the amount of consideration that the Company expects to be entitled to in exchange for transferred goods or services. A contract’s transaction price is allocated to each distinct performance obligation and revenue is recognized as the performance obligation is satisfied. For the majority of our contracts, the Company may provide distinct goods or services, in which case we separate the contract into more than one performance obligation (i.e., a good or service is individually listed in a contract or sold individually to a customer). The Company generally sells products and services with observable standalone selling prices. The performance obligations for the majority of RBC’s product sales are satisfied at the point in time in which the products are shipped, consistent with the pattern of revenue recognition under the previous accounting standard. The Company has determined that the customer obtains control upon shipment of the product based on the shipping terms (either when it ships from RBC’s dock or when the product arrives at the customer’s dock) and recognizes revenue accordingly. Once a product has shipped, the customer is able to direct the use of, and obtain substantially all of the remaining benefits from, the asset. Approximately 94% of the Company’s revenue was recognized in this manner based on sales for the three and nine-month periods ended December 29, 2018, respectively. The Company has determined performance obligations are satisfied over time for customer contracts where RBC provides services to customers and also for a limited number of product sales. RBC has determined revenue recognition over time is appropriate for our service revenue contracts as they create or enhance an asset that the customer controls throughout the duration of the contract. Approximately 6% of the Company’s revenue was recognized in this manner based on sales for the three and nine-month periods ended December 29, 2018, respectively. Revenue recognition over time is appropriate for customer contracts with product sales in which the product sold has no alternative use to RBC without significant economic loss and an enforceable right to payment exists, including a normal profit margin from the customer, in the event of contract termination. These types of contracts comprised less than 1% of total sales for both the three and nine-month periods ended December 29, 2018, respectively. For both of these types of contracts, revenue is recognized over time based on the extent of progress towards completion of the performance obligation. The Company utilizes the cost-to-cost measure of progress for over-time revenue recognition contracts as we believe this measure best depicts the transfer of control to the customer, which occurs as we incur costs on contracts. Revenues, including profits, are recorded proportionally as costs are incurred. Costs to fulfill include labor, materials, subcontractors’ costs, and other direct and indirect costs. Contract costs are the incremental costs of obtaining and fulfilling a contract (i.e., costs that would not have been incurred if the contract had not been obtained) to provide goods and services to customers. Contract costs largely consist of design and development costs for molds, dies and other tools that RBC will own and that will be used in producing the products under the supply arrangements. These contract costs are amortized to expense on a systematic and rational basis over a period consistent with the transfer to the customer of the goods or services to which the asset relates. Costs incurred to obtain a contract are primarily related to sales commissions and are expensed as incurred as they are generally not tied to specific customer contracts. These costs are included within selling, general and administrative costs on the consolidated statements of operations. In certain contracts, the Company facilitates shipping and handling activities after control has transferred to the customer. The Company has elected to record all shipping and handling activities as costs to fulfill a contract. In situations where the shipping and handling costs have not been incurred at the time revenue is recognized, the estimated shipping and handling costs are accrued. In June 2018, the FASB issued ASU No. 2018-07, Compensation – Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting, as part of its simplification initiative. This update will expand the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. This ASU also clarifies that Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. This update is effective for public companies for fiscal years beginning after December 15, 2018, including interim periods within that year. Early adoption is permitted, but no earlier than a company’s adoption of Topic 606. The Company has early adopted this ASU in the second quarter of fiscal 2019 and it did not have a material impact on the Company’s consolidated financial statements. In May 2017, the FASB issued ASU No. 2017-09, Compensation – Stock Compensation (Topic 718): Scope of Modification Accounting, in an effort to reduce diversity in practice as it relates to applying modification accounting for changes to the terms and conditions of share-based payment awards. This ASU was effective for public companies for financial statements issued for annual periods beginning after December 15, 2017, including interim periods within those annual periods. Early adoption was permitted. The Company adopted this ASU on April 1, 2018 and it did not have a material impact on the Company’s consolidated financial statements. In March 2017, the FASB issued ASU No. 2017-07, Compensation – Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, in an effort to improve the presentation of these costs within the income statement. Prior to this ASU, all components of both net periodic pension cost and net periodic postretirement cost were included within the same line items as other compensation costs arising from services rendered by pertinent employees during the period on the income statement. This ASU requires entities to include only the service cost component within those line items and all other components are to be included within other non-operating expense. In addition, only the service cost component would be eligible for capitalization when applicable (for example, as a cost of internally manufactured inventory or a self-constructed asset). The amendments in this ASU should be applied retrospectively for the presentation of the service cost component and the other components of net periodic pension cost and net periodic postretirement benefit cost in the income statement and prospectively, on and after the effective date, for the capitalization of the service cost component of net periodic pension cost and net periodic postretirement benefit in assets. This ASU was effective for public companies for the financial statements issued for annual periods beginning after December 15, 2017, including interim periods within those annual periods. A practical expedient allows the Company to use the amount disclosed for net periodic benefit costs for the prior comparative periods as the estimation basis for applying the retrospective presentation requirements. The Company retrospectively adopted the ASU on April 1, 2018 and utilized this practical expedient. The adoption of this ASU resulted in the reclassification of $159 of net periodic benefit cost from compensation costs ($107 included within cost of sales and $52 within other, net) to other non-operating expense on the consolidated statement of operations for the three-month period ended December 30, 2017 and $477 of net periodic benefit cost from compensation costs ($321 included within cost of sales and $156 within other, net) to other non-operating expense on the consolidated statement of operations for the nine-month period ended December 30, 2017. In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory, in an effort to improve the accounting for the income tax consequences of intra-entity transfers of assets other than inventory. Previous GAAP prohibited 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 established 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 was 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 adoption was 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 adopted this ASU on April 1, 2018 and it did not have a material impact on the Company’s consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. This ASU was 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 adoption was 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 adopted this ASU on April 1, 2018 and it did not have a material impact on the Company’s consolidated financial statements.
Recent Accounting Standards Yet to Be Adopted	Recent Accounting Standards Yet to Be Adopted In February 2018, the FASB issued ASU No. 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income which allows companies to reclassify stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017 (TCJA or “the Act”) from accumulated other comprehensive income to retained earnings. These stranded tax effects refer to the tax amounts included in accumulated other comprehensive income at the previous 35% U.S. corporate statutory federal tax rate, for which the related deferred tax asset or liability was remeasured to the new 21% U.S. corporate statutory federal tax rate in the period of the TCJA’s enactment. The new standard is effective for fiscal years beginning after December 15, 2018, with early adoption permitted, and can be applied either in the period of adoption or retrospectively to each period impacted by the TCJA. The Company is evaluating the effect of adopting this new accounting guidance, but does not expect adoption will have a material impact on the Company’s financial position as the adjustment will be between accumulated other comprehensive income and retained earnings, both of which are components of total stockholders’ equity. In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The objective of this standard update is to simplify the subsequent measurement of goodwill, eliminating Step 2 from the goodwill impairment test. Under this ASU, an entity should perform its annual goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity would recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value, assuming the loss recognized does not exceed the total amount of goodwill for the reporting unit. The standard update is effective for fiscal years beginning after December 15, 2019. Early adoption is permitted. The adoption of this ASU is not expected to have a material impact on the Company’s consolidated financial statements. In September 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments, which changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The new guidance will replace the current incurred loss approach with an expected loss model. The new expected credit loss impairment model will apply to most financial assets measured at amortized cost and certain other instruments, including trade and other receivables, loans, held-to-maturity debt instruments, net investments in leases, loan commitments and standby letters of credit. Upon initial recognition of the exposure, the expected credit loss model requires entities to estimate the credit losses expected over the life of an exposure (or pool of exposures). The estimate of expected credit losses should consider historical information, current information and reasonable and supportable forecasts, including estimates of prepayments. Financial instruments with similar risk characteristics should be grouped together when estimating expected credit losses. ASU 2016-13 does not prescribe a specific method to make the estimate, so its application will require significant judgment. This ASU is effective for public companies in fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company is currently evaluating the effect that the adoption of this ASU will have on the Company’s consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The core principle of this ASU 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 and early adoption is permitted. The Company has formed an implementation team to assess its leases as defined under the new accounting standard and anticipates making certain changes to existing processes, policies and systems during implementation. The Company anticipates the amended guidance will have a material impact on its assets and liabilities due to the addition of right-of-use assets and lease liabilities to the balance sheet; however, it does not expect the amended guidance to have a material impact on its cash flows, results of operations or debt covenant compliance. Other new pronouncements issued but not effective until after March 30, 2019 are not expected to have a material impact on our financial position, results of operations or liquidity.
