Organization, Consolidation and Presentation of Financial Statements [Abstract]

Organization and Business

Basis of Presentation

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 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 1, 2017. We condensed or omitted certain information and footnote disclosures normally included in our annual audited financial statements, which we prepared in accordance with U.S. Generally Accepted Accounting Principles (U.S. GAAP). As used in this report, the terms “we”, “us”, “our”, “RBC” and the “Company”) mean RBC Bearings Incorporated and its subsidiaries, unless the context indicates another meaning.

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 30, 2017 are not necessarily indicative of the operating results for the entire fiscal year ending March 31, 2018. The three month periods ended December 30, 2017 and December 31, 2016 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 three 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 30, 2017, 1.8% of the Company’s total net sales were recognized under Ship-In-Place transactions.

Recent Accounting Pronouncements

In May 2017, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (“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 is effective for public companies for the financial statements issued for annual periods beginning after December 15, 2017, including interim periods within those annual periods. 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 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. Under current GAAP, all components of both net periodic pension cost and net periodic postretirement cost are included within selling, general and administrative costs on the income statement. This ASU would require entities to include only the service cost component within selling, general and administrative costs whereas all other components would 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 Update 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 is effective for public companies for the financial statements issued for annual periods beginning after December 15, 2017, including interim periods within those annual periods. 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 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 October 2016, the FASB issued ASU No. 2016-16, “Income Taxes (Topic 740)”, 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 (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 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. The Company adopted this standard on April 2, 2017. As a result of the adoption, the Company began recording the tax effects associated with stock-based compensation through the income statement on a prospective basis which resulted in a tax benefit of $3.9 million for the first nine months of fiscal 2018. Prior to adoption, these amounts would have been recorded as an increase to additional paid-in capital. This change may create volatility in the Company's effective tax rate. The adoption of this standard also resulted in a cumulative effect change to opening retained earnings of $1.1 million for previously unrecognized excess tax benefits.

In addition, the Company will prospectively classify all tax-related cash flows resulting from share-based payments, including the excess tax benefits related to the settlement of stock-based awards, as cash flows from operating activities in the statement of cash flows. Prior to the adoption of this standard, these were shown as cash inflows from financing activities and cash outflows from operating activities.

The adoption of the ASU also resulted in the Company removing the excess tax benefits from the assumed proceeds available to repurchase shares when calculating diluted earnings per share on a prospective basis. The revised calculation increased the diluted weighted average common shares outstanding by approximately 0.1 million shares in the period of adoption. The Company also made an accounting policy election to continue to estimate forfeitures as it did prior to adoption.

In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842).” 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, “Inventory (Topic 330): 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. The Company adopted this ASU on a prospective basis on April 2, 2017 and it did not have a material impact on the Company’s consolidated financial statements.

In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)". The objective of this standard update is to remove inconsistent practices with regards to revenue recognition between U.S. GAAP and IFRS. The standard intends to improve comparability of revenue recognition practices across entities, industries, jurisdictions and capital markets. The provisions of ASU No. 2014-09 will be effective for interim and annual periods beginning after December 15, 2017, with early adoption permitted for annual periods beginning after December 15, 2016.

The guidance permits use of either a retrospective or cumulative effect transition method. Based upon the FASB's decision to approve a one-year delay in implementation, the new standard is now effective for the Company in fiscal 2019, with early adoption permitted, but not earlier than fiscal 2018. The Company has concluded it will utilize the modified retrospective method upon adopting this standard.

The Company has substantially completed their assessment of the impact of the new standard on its business which has identified potential differences that would result from applying the requirements of the new standard to its revenue contracts. Upon adoption, the Company expects certain revenue streams currently accounted for using a point-in-time model will utilize an over-time model due to the continuous transfer of control to customers. The Company is in the process of drafting updated accounting policies and disclosures under the new guidance. The Company has not finalized the impact of reported revenues and earnings of adopting the new standard but expects to do so by the end of the fourth quarter of fiscal 2018.

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:

At December 30, 2017, no employee stock options have been excluded from the calculation of diluted earnings per share. At December 31, 2016, 449,500 employee stock options have been excluded from the calculation of diluted earnings per share. The inclusion of these employee stock options would be anti-dilutive.

The current portion of long-term debt as of both December 30, 2017 and April 1, 2017 includes the current portion of the Schaublin mortgage and the current portion of the Term Loan Facilities.

Credit Facility

In connection with the Sargent Aerospace & Defense (“Sargent”) acquisition on April 24, 2015, the Company entered into a new 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 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”). 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 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 0.00% for base rate loans and 1.00% for LIBOR rate loans. As of December 30, 2017, there was $21,750 outstanding under the Revolver and $172,500 outstanding under the Term Loan, offset by $3,324 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 be less than 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 30, 2017, 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 $3,990 of the Revolver is being utilized to provide letters of credit to secure RBCA’s obligations relating to certain insurance programs. As of December 30, 2017, RBCA has the ability to borrow up to an additional $324,260 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 30, 2017 was 6,859 CHF, or $7,027.

Income Taxes

7. 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, 2014. 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 30, 2017 and December 31, 2016 were 23.9% and 31.5%, respectively. During the third quarter, Congress passed and the President signed the Tax Cuts and Jobs Act (“TCJA”) of 2017 into law. The new law includes a number of changes in existing tax law impacting businesses including a permanent reduction in the corporate income tax rate from 35.0% to 21.0%. As a result, the blended statutory rate applied for the current fiscal year is 31.5%. As of December 30, 2017, we have not completed our accounting for the tax effects associated with the TCJA. The impacts recorded, as detailed below, represent our estimate of the impact during the current fiscal year. 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 increase the rate.

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%. The third quarter provision was also impacted by approximately $1,238 of benefit associated with the adoption of ASU 2016-09 Compensation - Stock Compensation (Topic 718) Improvements to Employee Share-Based Payment Accounting and $45 of other discrete expense related to federal and state tax filing positions. The effective income tax rate without discrete items for the three month period ended December 30, 2017 would have been 25.3%. 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 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 $531.

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 consist 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.

Integration and Restructuring of Operations

9. Integration and Restructuring of Operations

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 expects to close its RBC Canada location and consolidate certain residual assets into other locations by the end of this fiscal year. 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 includes 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 the “Other, net” line item 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 are 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 are comprised of customer relationships, product approvals, tradenames and trademarks. In the third quarter of fiscal 2018, the Company incurred restructuring charges of $1,091 comprised primarily of employee termination costs. These costs were recorded within the “Other, net” line item within the consolidated statement of operations and are all attributable to the Engineered Products segment. The cumulative restructuring charges as of the end of the third quarter of fiscal 2018, net of taxes, were $6,668. The total impact of this restructuring is expected to be between $7,000 and $7,500 in after-tax charges, all attributable to the Engineered Products segment, and is expected to conclude in the third quarter of fiscal 2019.

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 exited a few smaller product offerings and consolidated 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.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation 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 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 1, 2017. We condensed or omitted ceratin information and footnote disclosues normally included in our annual audited financial statements, which we prepared in accordance with U.S. Generally Accepted Accounting Principles (U.S. GAAP). As used in this report, the terms “we”, “us”, “our”, “RBC” and the “Company”) mean RBC Bearings Incorporated and its subsidiaries, unless the context indicates another meaning. 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 30, 2017 are not necessarily indicative of the operating results for the entire fiscal year ending March 31, 2018. The three month periods ended December 30, 2017 and December 31, 2016 each include 13 weeks. The amounts shown are in thousands, unless otherwise indicated.
Critical Accounting Policies	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 three 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 30, 2017, 1.8% of the Company’s total net sales were recognized under Ship-In-Place transactions.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2017, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (“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 is effective for public companies for the financial statements issued for annual periods beginning after December 15, 2017, including interim periods within those annual periods. 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 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. Under current GAAP, all components of both net periodic pension cost and net periodic postretirement cost are included within selling, general and administrative costs on the income statement. This ASU would require entities to include only the service cost component within selling, general and administrative costs whereas all other components would 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 Update 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 is effective for public companies for the financial statements issued for annual periods beginning after December 15, 2017, including interim periods within those annual periods. 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 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 October 2016, the FASB issued ASU No. 2016-16, “Income Taxes (Topic 740)”, 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 (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 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. The Company adopted this standard on April 2, 2017. As a result of the adoption, the Company began recording the tax effects associated with stock-based compensation through the income statement on a prospective basis which resulted in a tax benefit of $3.9 million for the first nine months of fiscal 2018. Prior to adoption, these amounts would have been recorded as an increase to additional paid-in capital. This change may create volatility in the Company's effective tax rate. The adoption of this standard also resulted in a cumulative effect change to opening retained earnings of $1.1 million for previously unrecognized excess tax benefits. In addition, the Company will prospectively classify all tax-related cash flows resulting from share-based payments, including the excess tax benefits related to the settlement of stock-based awards, as cash flows from operating activities in the statement of cash flows. Prior to the adoption of this standard, these were shown as cash inflows from financing activities and cash outflows from operating activities. The adoption of the ASU also resulted in the Company removing the excess tax benefits from the assumed proceeds available to repurchase shares when calculating diluted earnings per share on a prospective basis. The revised calculation increased the diluted weighted average common shares outstanding by approximately 0.1 million shares in the period of adoption. The Company also made an accounting policy election to continue to estimate forfeitures as it did prior to adoption. In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842).” 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, “Inventory (Topic 330): 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. The Company adopted this ASU on a prospective basis on April 2, 2017 and it did not have a material impact on the Company’s consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)". The objective of this standard update is to remove inconsistent practices with regards to revenue recognition between U.S. GAAP and IFRS. The standard intends to improve comparability of revenue recognition practices across entities, industries, jurisdictions and capital markets. The provisions of ASU No. 2014-09 will be effective for interim and annual periods beginning after December 15, 2017, with early adoption permitted for annual periods beginning after December 15, 2016. The guidance permits use of either a retrospective or cumulative effect transition method. Based upon the FASB's decision to approve a one-year delay in implementation, the new standard is now effective for the Company in fiscal 2019, with early adoption permitted, but not earlier than fiscal 2018. The Company has concluded it will utilize the modified retrospective method upon adopting this standard. The Company has substantially completed their assessment of the impact of the new standard on its business which has identified potential differences that would result from applying the requirements of the new standard to its revenue contracts. Upon adoption, the Company expects certain revenue streams currently accounted for using a point-in-time model will utilize an over-time model due to the continuous transfer of control to customers. The Company’s maintenance, repair and overhaul (MRO) revenue stream will be most impacted by this change resulting from the new standard. The Company is in the process of drafting updated accounting policies and disclosures under the new guidance. The Company has not finalized the impact of reported revenues and earnings of adopting the new standard but expects to do so by the end of the fourth quarter of fiscal 2018.
