Basis Of Presentation

Basis Of Presentation	3 Months Ended
	Dec. 02, 2017
Basis Of Presentation	Note 1. Basis of Presentation  The accompanying condensed consolidated financial statements include MSC Industrial Direct Co., Inc. (“MSC”) and all of its subsidiaries (hereinafter referred to collectively as the “Company”). All intercompany balances and transactions have been eliminated in consolidation.  The unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by accounting principles generally accepted in the United States for complete financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation (consisting of normal recurring adjustments) have been included. Operating results for the thirteen- week period ended December 2, 2017 is not necessarily indicative of the results that may be expected for the fiscal year ending September 1, 2018 . For further information, refer to the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 2, 2017 .   The Company’s fiscal year ends on the Saturday closest to August 31 of each year. Unless the context requires otherwise, references to years contained herein pertain to the Company’s fiscal year. The Company’s 2018 fiscal year will be a 52 -week accounting period that will end on September 1, 2018 and its 2017 fiscal year was a 52 -week accounting period that ended on September 2, 2017 .  There have been no changes to significant accounting policies since September 2, 2017. As a result of the Company’s adoption of Accounting Standards Update (“ASU”) No. 2016-09, Improvements to Employee Share-Based Payment Accounting in the second quarter of fiscal 2017, adjustments were recorded to the thirteen-week period ended December 3, 2016, which was the beginning of the annual period of adoption.  Recently Adopted Accounting Pronouncements  Share-based Payments  In March 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting, which includes provisions intended to simplify various aspects related to how share-based payments are accounted for and presented in the financial statements. The Company early adopted ASU 2016-09 in the second quarter of fiscal 2017, which required us to reflect any adjustments as of September 4 , 2016, the beginning of the annual period that includes the interim period of adoption. Prior fiscal year periods were not retrospectively adjusted.  Adoption of the new standard affected our previously reported fiscal first quarter of 2017 net income per share as follows:     Thirteen Weeks Ended  December 3, 2016  As Reported As Adjusted Condensed Consolidated Statements of Income: (in thousands, except per share data)  Provision for income taxes $ 33,442 $ 33,257  Net income $ 54,103 $ 54,288 Per share information: Net income per common share:  Basic $ 0.96 $ 0.96  Diluted $ 0.95 $ 0.96 Weighted average shares used in computing net income per common share:  Basic 56,381 56,381  Diluted 56,572 56,608  Deferred Taxes  In November 2015, the FASB issued ASU No. 2015-17, Balance Sheet Classification of Deferred Taxes. This update requires an entity to classify deferred tax liabilities and assets as non-current within a classified balance sheet. ASU 2015-17 is effective for annual reporting periods, and interim periods therein, beginning after December 15, 2016. This update may be applied either prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. The FASB allowed early adoption of this standard and, therefore, the Company prospectively adopted ASU 2015-17 during its first quarter of fiscal 2017. As a result of adopting this standard, $46,627 of deferred income taxes that were previously presented as a current asset are now included within long-term liabilities, as the Company was in a net deferred tax liability position in its first quarter of fiscal 2017 which was the time of adoption. Prior periods were not retrospectively adjusted.  Simplifying the Measurement of Inventory  In July 201 5, the FASB issued ASU No. 201 5-11, Simplifying the Measurement of Inventory ( Topic 330), which requires an entity to measure inventory at the lower of cost and net realizable value, which consists of the estimated selling prices in the ordinary course of business, less reasonably predictable cost s of completion, disposal, and transportation. For public entities, the updated guidance is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The guidance is to be applied prospectively with earlier application permitted as of the beginning of an interim or annual reporting period. The Company adopted ASU 2015-11 during the first quarter of fiscal 2018 and the adoption did not have any impact on its consolidated financial statements.  Accounting Pronouncements Not Yet Adopted  Goodwill Impairment  In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment . ASU 2017-04 simplifies the subsequent measurement of goodwill by eliminating Step 2 in the goodwill impairment test that required an entity to calculate the implied fair value of goodwill. An entity will now apply a one-step quantitative test and record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value. ASU 2017-04 will be applied prospectively and is effective for annual and interim goodwill impairment tests conducted in fiscal years beginning after December 15, 2019 . The new standard is effective for the Company for its fiscal 2021 fourth quarter goodwill impai rment test. Early adoption is permitted for annual and interim goodwill impairment testing dates after January 1, 2017. The Company does not expect the adoption of ASU 2017-04 to have a material impact on its consolidated financial statements.  Business Combinations  In January 2017, the FASB issued ASU No. 2017-01, Business Combinations – Clarifying the Definition of a Business. ASU 2017-01 clarifies the definition of a business to assist entities with evaluating when a set of transferred assets and activities is considered a business. The amendment is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The new standard is effective for the Company for its fiscal year 2019, with early adoption permitted. The amendments are to be applied prospectively to business combinations that occur after the effective date.  Leases  In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), to increase transparency and comparability by providing additional information to users of financial statements regarding an entity’s leasing activities. ASU 2016-02 requires reporting entities to recognize lease assets and lease liabilities on the balance sheet for substantially all lease arrangements. ASU 2016-02 is effective for annual reporting periods, and interim periods therein, beginning after December 15, 2018. The new standard is effective for the Company for its fiscal year 2020. The guidance will be applied on a modified retrospective basis beginning with the earliest period presented. The Company is currently evaluating this standard to determine the impact of adoption on its consolidated financial statements.  Revenue from Contracts with Customers  In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in GAAP when it becomes effective. The new standard is effective for the Company for its fiscal year 2019. Early adoption is permitted. The standard permits the use of either the retrospective or cumulative effect transition method. To date, the Company has performed a preliminary detailed review of key contracts and compared historical accounting policies and practices to the new standard. While the Company is still evaluating this standard, it is not expected that this standard will have a material impact on the Company’s consolidated financial statements. The Company will continue to evaluate ASU 2014-09 and other amendments and related interpretive guidance through the date of adoption. The Company expects to adopt ASU 2014-09 under the modified retrospective approach in the first quarter of fiscal 2019.

Net Income Per Share	Note 2. Net Income per Share  The Company’s non-vested restricted stock awards contain non-forfeitable rights to dividends and meet the criteria of a participating security as defined by Ac counting Standards Codification (“ASC” ) Topic 260, “ Earnings Per Share” . Under the two-class method, net income per share is computed by dividing net income allocated to common shareholders by the weighted average number of common shar es outstanding for the period. In applying the two-class method, net income is allocated to both common shares and participating securities based on their respective weighted average shares outstanding for the period.  The following table sets forth the computation of basic and diluted net income per common share under the two-class method for the thirteen weeks ended December 2, 2017 and December 3, 2016 , respectively:     Thirteen Weeks Ended  December 2, December 3,  2017 2016  Net income as reported $ 59,585 $ 54,288  Less: Distributed net income available to participating securities (34) (77)  Less: Undistributed net income available to participating securities (69) (114)  Numerator for basic net income per share:  Undistributed and distributed net income available to common shareholders $ 59,482 $ 54,097  Add: Undistributed net income allocated to participating securities 69 114  Less: Undistributed net income reallocated to participating securities (69) (114)   Numerator for diluted net income per share:  Undistributed and distributed net income available to common shareholders $ 59,482 $ 54,097  Denominator:  Weighted average shares outstanding for basic net income per share 56,287 56,381  Effect of dilutive securities 217 227  Weighted average shares outstanding for diluted net income per share 56,504 56,608  Net income per share Two-class method:  Basic $ 1.06 $ 0.96  Diluted $ 1.05 $ 0.96  Antidilutive stock options of 957 and 606 were not included in the computation of diluted earnings per share for the thirteen -week periods ended December 2, 2017 and December 3, 2016, respectively.

	Dec. 02, 2017
Stock-Based Compensation	Note 3. Stock-Based Compensation  The Company accounts for all share-based payments in accordance with ASC Topic 718, "Compensation—Stock Compensation" ("ASC 718"). S tock ‑based compensation expense included in operating expenses for the thirteen-week periods ended December 2, 2017 and December 3, 2016 was as follows:     Thirteen Weeks Ended  December 2, December 3,  2017 2016  Stock options $ 1,194 $ 1,112  Restricted share awards 902 1,322  Restricted stock units 1,754 1,042  Associate Stock Purchase Plan 44 62  Total 3,894 3,538  Deferred income tax benefit (1,480) (1,344)  Stock-based compensation expense, net $ 2,414 $ 2,194  Stock options  The fair value of each option grant is estimated on the date of grant using the Black ‑Scholes option pricing model with the following assumptions:     Thirteen Weeks Ended  December 2, December 3,  2017 2016  Expected life (in years) 4.0 4.1  Risk-free interest rate 1.87 % 1.16 %  Expected volatility 22.13 % 20.50 %  Expected dividend yield 2.30 % 2.40 %  Weighted-average grant-date fair value $12.25 $9.29  A summary of the Company’s stock option activity for the thirteen-week period ended December 2, 2017 is as follows:     Options Weighted-Average Exercise Price per Share Weighted-Average Remaining Contractual Term (in years) Aggregate Intrinsic Value  Outstanding on September 2, 2017 1,743 $ 70.88  Granted 436 79.60  Exercised (36) 66.53  Canceled/Forfeited (17) 73.25  Outstanding on December 2, 2017 2,126 $ 72.72 4.9 $ 37,520  Exercisable on December 2, 2017 959 $ 73.19 3.7 $ 16,480  The unrecognized share ‑based compensation cost related to stock option expense at December 2, 2017 was $11,149 and will be recognized over a weighted average period of 2.9 years. The total intrinsic va lue of options exercised, which represents the difference between the exercise price and market value of common stock measured at each individual exercise d ate, during the thirteen -week periods ended December 2, 2017 and December 3, 2016 was $577 and $1,596 , respectively.  Restricted share awards  A summary of the non ‑vested restricted share award (“RSA”) activity under the Company’s 2005 Omnibus Incentive Plan and 2015 Omnibus Incentive Plan for the thirteen -week period ended December 2, 2017 is as follows:      Shares Weighted-Average Grant-Date Fair Value  Non-vested restricted share awards at September 2, 2017 160 $ 80.49  Granted — —  Vested (86) 79.45  Canceled/Forfeited (1) 82.27  Non-vested restricted share awards at December 2, 2017 73 $ 81.56  The fair value of each RSA is the closing stock price on the New York Stock Exchange of the Company’s Class A common stock on the date of grant. Upon vesting, a portion of the RSA award may be withheld to satisfy the statutory income tax withholding obligation. The remaining RSAs will be settled in shares of the Company’s Class A common stock when vested. The unrecognized compensation cost related to RSAs at December 2, 2017 was $3,966 and will be recognized over a weighted average period of 1.6 years.  Restricted stock units  A summa ry of the Company’s non-vested Restricted Stock U nit (“RSU”) award activity for the thirteen- week period ended December 2, 2017 is as follows:     Shares Weighted-Average Grant-Date Fair Value  Non-vested restricted stock unit awards at September 2, 2017 313 $ 66.66  Granted 152 79.60  Vested (65) 65.04  Canceled/Forfeited (6) 69.90  Non-vested restricted stock unit awards at December 2, 2017 394 $ 71.88  The fair value of each RSU is the closing stock price on the New York Stock Exchange of the Company’s Class A common stock on the date of grant. Upon vesting, a portion of the RSU award may be withheld to satisfy the statutory income tax withholding obligation . The remaining RSUs will be settled in shares of the Company’s Class A common stock when vested . These awards accrue dividend equivalents on outstanding units (in the form of additional stock units) based on dividends declared on the Company’s Class A common stock and these dividend equivalents convert to unrestricted common stock on the vesting dates of the underlying RSUs . The dividend equivalents are not included in the RSU table above. The unrecognized compensation cost related to the RSUs at December 2, 2017 was $23,744 and is expected to be recognized over a weighted average period of 3.8 years.

Fair Value

Fair Value	3 Months Ended
	Dec. 02, 2017
Fair Value	Note 4. Fair Value  Fair value accounting standards define fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The following fair value hierarchy prioritizes the inputs used to measure fair value into three levels, with Level 1 being of the highest priority. The three levels of inputs used to measure fair value are as follows:   Level 1 — Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active m arkets .  Level 2 — Include other inputs that are directly or indirectly observable in the marketplace.  Level 3 — Unobservable inputs which are supported by little or no market activity.  In connection with the co nstruction of the Company’s customer fulfillment center in Columbus, Ohio, the Company entered into an arrangement during fiscal 2013 with the Columbus-Franklin County Finance Authority (“Finance Authority”) which provides savings on state and local sales taxes imposed on construction materials to entities that finance the transactions through them. Under this arrangement, the Finance Authority issued taxable bonds to finance the structure and site improvements of the Company’s c ustomer fulfillment center. The bonds ( $27,025 outstanding at both December 2, 2017 and September 2, 2017 ) are classified as available for sale securities in accordance with ASC Topic 320. The securities are recorded at fair value in Other Assets in the Condensed Consolidated Balance Sheet. The fair values of these securities are based on observable inputs in non-active markets, which are therefore classified as Level 2 in the hierarchy. The Company did not record any gains or losses on these securities during the thirteen -w eek period ended December 2, 2017 . The outstanding principal amount of each bond bears interest at the rate of 2.4% per year. Interest is payable on a semiannual basis in arrears on each interest payment date.  In addition, based on borrowing rates currently available to the Company for borrowings with similar terms, the carrying values of the Company’s capital lease obligations also approximate fair value. The fair value of the Company’s short-term and long-term deb t is estimated based on quoted market prices for the same or similar issues or on current rates offered to the Company for debt of the same remaining maturities. The carrying amount of the Company’s debt at December 2, 2017 approximates its fair value.  The Company’s financial instruments, other than those presented in the disclosure above, include cash, receivables, accounts payable, and accrued liabilities. Management believes the carrying amount of the aforementioned financial instruments is a reasonable estimate of fair value as of December 2, 2017 and September 2, 2017 due to the short-term maturity of these items.  During the thirteen weeks ended December 2, 2017 and December 3, 2016 , the Company had no measurements of non-financial assets or liabilities at fair value on a non-recurring basis subsequent to their initial recognition.

Credit Facility  In April 2017, the Company entered into a $600,000 credit facility (the “ Credit Facility”). The Credit Facility, which matures on April 14, 2022 , provides for a five -year unsecured revolving loan facility in the aggregate amount of $600,000 .  The Credit Facility permits up to $50,000 to be used to fund letters of credit. The Credit Facility also permits the Company to request one or more incremental term loan facilities and/or increase the revolving loan commitments in an aggregate amount not to exceed $300,000 . Subject to certain limitations, each such incremental term loan facility or revolving commitment increase will be on terms as agreed to by the Company, the Administrative Agent and the lenders providing such financing.  Borrowings under the Credit Facility bear interest, at the Company’s option, either at (i) the LIBOR (London Interbank Offered Rate) rate plus the applicable margin for LIBOR loans ranging from 1.00% to 1.375% , based on the Company’s consolidated leverage ratio; or (ii) the greatest of (a) the Administrative Agent’s prime rate in effect on such day, (b) the federal funds effective rate in effect on such day, plus 0.50% and (c) the LIBOR rate that would be calculated as of such day in respect of a proposed LIBOR loan with a one-month interest perio d, plus 1.00%, plus, in th e case of each of clauses (a) through (c), an applicable margin ranging from 0.00% to 0.375% , based on the Company’s consolidated leverage ratio. The Company is required to pay a quarterly undrawn fee ranging from 0.10% to 0.20% per annum on the unutilized portion of the Credit Facility, based on the Company’s consolidated leverage ratio. The Company is also required to pay quarterly letter of credit usage fees ranging between 1.00% to 1.375% (based on the Company’s consolidated leverage ratio) on the amount of the daily average outstanding letters of credit, and a quarterly fronting fee of 0.125% per annum on the undrawn and unexpired amount of each letter of credit . The weighted average applicable borrowing rate for the Company for any borrowings outstanding under the Credit Facility at December 2, 2017 was 2.46% which represents LIBOR plus 1.125% . Based on the interest period the Company selects, interest may be payable every one, two, three or six months. Interest is reset at the end of each interest period. The Company currently elects to have loans under the Credit Facility bear interest based on LIBOR with one -month interest periods.  During the thirteen -w eek period ended December 2, 2017 , the Company borrowed $24,000 and repaid $65,000 under the revolving loan facility.  Private Placement Debt  In July 201 6, in connection with the Company’s “modified Dutch auction” tender offer, the Company completed the issuance and sale of the following unsecured senior notes (collectively “Private Placement Debt”):  · $75,000 aggregate principal amount of 2.65% Senior Notes, Series A, due July 28, 2023 (“Senior notes, series A”); and · $100,000 aggregate principal amount of 2.90% Senior Notes, Series B, due July 28, 2026 (“Senior notes, series B”).  The Private Placement Debt is due, in full, on the stated maturity dates. Interest is payable semiannually at the fixed stated interest rates.  The Credit Facility and Private Placement Debt contain several restrictive covenants including the requirement that the Company maintain a maximum consolidated leverage ratio of total indebtedness to EBITDA (earnings before interest expense, taxes, depreciation, amortization and stock-based compensation) of no more than 3.00 to 1.00 (or, at the election of the Company after it consummates a material acquisition, a four-quarter temporary increase to 3.50 to1.00) , and a minimum consolidated interest coverage ratio of EBITDA to total interest expense of at least 3.00 to 1.00, during the term s of the Credit Facility and Private Placement Debt.  At December 2, 2017 , the Company was in compliance with the operating and financial covenants of the Credit Facility and Private Placement Debt.  Capital Lease and Financing Obligations  In connection with the construction of the Company’s customer fulfillment center in Columbus, Ohio, the Finance Authority holds the title to the building and entered into a long-term lease with the Company. The lease has a 20 -year term with a prepayment option without penalty between 7 and 20 years. At the end of the lease term, the building’s title is transferred to the Company for a nominal amount when the principal of and interest on the bonds have been fully paid. The lease has been classified as a capital lease in accordance with ASC Topic 840. At December 2, 2017 and September 2, 2017 , the capital lease obligation was approximately $27,025 .  From time to time, the Company enters into capital leases and financing arrangements with vendors to purchase certain IT equipment or software. The equipment or software acquired from these vendors is paid over a specified period of time based on the terms agreed upon. During the thirteen-week period ended December 2, 2017, the Company entered into a financing obligation for certain software totaling $721 . The gross amount of property and equipment acquired under this financing obligation at December 2, 2017 was approximately $721 . Related accumulated amortization totaled $120 as of December 2, 2017.
