Summary of Significant Accounting Policies
Summary of Significant Accounting Policies	1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation. ​ Financial Statement Presentation. ​ Use of Estimates and Assumptions in the Preparation of Financial Statements. ​ Revenue Recognition. Note 8 – Segment Information ​ We recognize revenue for our Installation segment over time as the related performance obligation is satisfied with respect to each particular order within a given customer’s contract. Progress toward complete satisfaction of the performance obligation is measured using a cost-to-cost measure of progress method. The cost input is based on the amount of material installed at that customer’s location and the associated labor costs, as compared to the total expected cost for the particular order. The total expected cost is a significant estimate in the revenue recognition process, requires judgment, and is subject to variability throughout the duration of the contract as a result of contract modifications and other circumstances impacting job completion. Generally, this results in revenue being recognized as the customer is able to receive and utilize the benefits provided by our services. Each contract contains one or more individual orders, which are based on services delivered. When material and installation services are bundled in a contract, we combine these items into one performance obligation as the overall promise is to transfer the combined item. ​ Revenue from our Specialty Distribution segment is recognized when title to products and risk of loss transfers to our customers. This represents the point in time when the customer is able to direct the use of and obtain substantially all the benefits from the product. The determination of when control is deemed transferred depends on the shipping terms that are agreed upon in the contract. ​ At time of sale, we record estimated reductions to revenue for customer programs and incentive offerings, including special pricing and other volume-based incentives based on historical experience, which is continuously adjusted. The duration of our contracts with customers is relatively short, generally less than a 90-day period, therefore there is not a significant financing component when considering the determination of the transaction price which gets allocated to the individual performance obligations, generally based on standalone selling prices. Additionally, we consider shipping costs charged to a customer as a fulfillment cost rather than a promised service and expense as incurred. Sales taxes, when incurred, are recorded as a liability and excluded from revenue on a net basis. ​ We record a contract asset when we have satisfied our performance obligation prior to billing and a contract liability when a customer payment is received prior to the satisfaction of our performance obligation. The difference between the beginning and ending balances of our contract assets and liabilities primarily results from the timing of our performance and the customer’s payment. See Note 3 – Revenue Recognition . Business Combinations ​ Cash and Cash Equivalents. ​ Receivables, net. ​ Inventories, net. ​ Inventory provisions are recorded to reduce inventory to the lower of cost or net realizable value for obsolete or slow moving inventory based on assumptions about future demand and marketability of products, the impact of new product introductions, inventory levels and turns, product spoilage, and specific identification of items such as product discontinuance, engineering/material changes, or regulatory-related changes. Our inventory reserve balances were $17.3 million and $11.2 million as of December 31, 2022 and 2021, respectively. As of December 31, 2022, and 2021, primarily all inventory consisted of finished goods. ​ Property and Equipment, net. ​ We review our property and equipment as an event occurs or circumstances change that would more likely than not reduce the fair value of the property and equipment below the carrying amount. If the carrying amount is not recoverable from its undiscounted cash flows, we would recognize an impairment loss for the difference between the carrying amount and the current fair value. Further, we evaluate the remaining useful lives of property and equipment at each reporting period to determine whether events and circumstances warrant a revision to the remaining depreciation periods. ​ Depreciation. ​ Asset Class Estimated Useful Life Buildings and land improvements 20 – 40 years Software 3 – 6 years Company vehicles 3 – 8 years Equipment 6 – 10 years ​ Leases ​ Lease payments are recognized as an expense in the consolidated statements of operations on a straight-line basis over the lease term, including future option periods the Company reasonably expects to exercise, whereby an equal amount of rent expense is attributed to each period during the term of the lease, regardless of when actual payments are made. This generally results in rent expense in excess of cash payments during the early years of a lease and rent expense less than cash payments in later years. The difference between rent expense recognized and actual rental payments is typically represented as the spread between the ROU asset and lease liability. ​ We recognize a ROU asset and a lease liability at the lease commencement date. Our leases may include options to extend or terminate the lease, which will be reflected in the calculation of the lease liability and corresponding ROU asset when it is reasonably certain that we will exercise that option. We do not recognize ROU assets and lease liabilities for short-term leases that have an initial lease term of 12 months or less. We recognize the lease payments associated with short-term leases as an expense on a straight-line basis over the lease term. ​ The lease liability is initially measured as the present value of the unpaid lease payments as of the lease commencement date. The lease liability is discounted based on our IBR at the time of modification for an existing lease or at the time of lease commencement for new leases. Our IBR includes significant assumptions regarding our secured borrowing rates obtained on equipment note issuances and adjustments for differences in the remaining lease term, underlying assets and market conditions for companies with similar credit qualities as well as interest rate index fluctuations. The ROU asset is initially measured at cost, which comprises the initial amount of the lease liability adjusted for lease payments made at or before the lease commencement date, plus any initial direct costs incurred less any lease incentives received. The ROU asset is subsequently measured throughout the lease term as the carrying amount of the lease liability, plus initial direct costs, plus (minus) any prepaid (accrued) lease payments, less the unamortized balance of lease incentives received. Certain vehicle lease agreements have residual value guarantees at the end of the lease which require us to return the asset with a specified percentage of the original or other calculated value. ​ Fair Value ​ Level 1: Quoted prices in active markets for identical assets or liabilities. ​ Level 2: Observable inputs other than Level 1 prices, such as quoted market prices for similar assets or liabilities or other inputs that are observable or can be corroborated by market data. ​ Level 3: Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions. ​ Goodwill and Other Intangible Assets. ​ Fair value for our reporting units is determined using a discounted cash flow method, which includes significant unobservable inputs (Level 3 inputs). Using the discounted cash flow method requires us to make significant estimates and assumptions, including long term projections of cash flows, market conditions, and appropriate discount rates. Our judgments are based upon historical experience, current market trends, consultations with external valuation specialists and other information. In estimating future cash flows, we rely on internally generated long-range forecasts for sales and operating profits, including capital expenditures. ​ Intangible assets with finite useful lives are amortized using the straight-line method over their estimated useful lives. We evaluate the remaining useful lives of amortizable intangible assets at each reporting period to determine whether events and circumstances warrant a revision to the remaining periods of amortization. For additional information, see Note 5 – Goodwill and Other Intangibles ​ Insurance Reserves. ​ Advertising ​ Share-based Compensation. ​ ​ ​ ​ ​ ​ Award Type: Fair Value Determination Vesting Expense Recognition‡ Expense Measurement Restricted Share Awards ​ ​ ​ ​ Service Condition Closing stock price on date of grant Ratably; 3 years Straight-line Fair value at grant date Performance Condition Closing stock price on date of grant Cliff; 3 years Straight-line; Evaluated quarterly; Market Condition Monte-Carlo Simulation Cliff; 3 years Straight-line; Fair value at grant date Stock Options† Black-Scholes Options Pricing Model Ratably; 3 or 5 years Straight-line Fair value at grant date †Stock options expire no later than 10 years after the grant date. ‡Expense is reversed if award is forfeited prior to vesting. ​ Debt Issuance Costs. ​ Income Taxes. ​ Valuation allowances are established against deferred tax assets when it is more likely than not that the realization of those deferred tax assets will not occur. In evaluating our ability to recover our deferred tax assets within the jurisdiction from which they arise, we consider all available positive and negative evidence. If, based upon all available evidence, both positive and negative, it is more likely than not (more than 50 percent likely) such deferred tax assets will not be realized, a valuation allowance is recorded. Significant weight is given to positive and negative evidence that is objectively verifiable. ​ Only those income tax positions that have a greater than 50 percent likelihood of being sustained upon examination by taxing authorities are recognized. There is an increased potential for volatility in our effective tax rate because of future changes in the income tax environment and the inherent complexities of income tax law in the various jurisdictions. Accordingly, provisions for tax-related matters, including interest and penalties, could be recorded in income tax expense in the period revised assessments are made. ​ Foreign Currency. ​ Recently Adopted Accounting Pronouncements ​ Credit Losses. ​ Contract Assets and Liabilities.

Goodwill and Other Intangibles	5. GOODWILL AND OTHER INTANGIBLES ​ We have two reporting units which are also our operating and reporting segments: Installation and Specialty Distribution. Both reporting units contain goodwill. Assets acquired and liabilities assumed are assigned to the applicable reporting unit based on whether the acquired assets and liabilities relate to the operations of such unit and determination of its fair value. Goodwill assigned to the reporting unit is the excess of the fair value of the acquired business over the fair value of the individual assets acquired and liabilities assumed for the reporting unit. In the fourth quarters of 2022 and 2021, we performed annual assessments of our goodwill resulting in no indicators of impairment. ​ Changes in the carrying amount of goodwill for the years ended December 31, 2022 and 2021, by segment, were as follows, in thousands: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Accumulated ​ ​ ​ ​ Gross Goodwill ​ ​ ​ Fx Translation ​ Gross Goodwill ​ Impairment ​ Net Goodwill ​ ​ December 31, 2021 ​ Additions ​ Adjustment ​ December 31, 2022 ​ Losses ​ December 31, 2022 Goodwill, by segment: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Installation ​ $ 1,818,872 ​ $ 8,107 ​ $ - ​ $ 1,826,979 ​ $ (762,021) ​ $ 1,064,958 Specialty Distribution ​ 892,912 ​ 10,585 ​ ​ (1,461) ​ 902,036 ​ - ​ 902,036 Total goodwill ​ $ 2,711,784 ​ $ 18,692 ​ $ (1,461) ​ $ 2,729,015 ​ $ (762,021) ​ $ 1,966,994 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Accumulated ​ ​ ​ ​ Gross Goodwill ​ ​ ​ Fx Translation ​ Gross Goodwill ​ Impairment ​ Net Goodwill ​ ​ December 31, 2020 ​ Additions ​ Adjustment ​ December 31, 2021 ​ Losses ​ December 31, 2021 Goodwill, by segment: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Installation ​ $ 1,726,356 ​ $ 92,516 ​ $ - ​ $ 1,818,872 ​ $ (762,021) ​ $ 1,056,851 Specialty Distribution ​ 446,350 ​ 451,331 ​ ​ (4,769) ​ 892,912 ​ - ​ 892,912 Total goodwill ​ $ 2,172,706 ​ $ 543,847 ​ $ (4,769) ​ $ 2,711,784 ​ $ (762,021) ​ $ 1,949,763 ​ ​ The following table sets forth our other intangible assets, in thousands: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of December 31, ​ ​ 2022 ​ 2021 ​ 2020 Gross definite-lived intangible assets $ 782,316 ​ $ 783,843 ​ $ 252,751 Accumulated amortization ​ (167,349) ​ ​ (99,634) ​ ​ (62,146) Net definite-lived intangible assets $ 614,967 ​ $ 684,209 ​ $ 190,605 Indefinite-lived intangible assets not subject to amortization ​ - ​ ​ - ​ ​ - Other intangible asset, net ​ $ 614,967 ​ $ 684,209 ​ $ 190,605 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Amortization expense ​ $ 67,620 ​ $ 36,501 ​ $ 21,886 ​ The following table sets forth a breakout of our intangible assets as of December 31, 2022, in thousands: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Gross Definite - lived Intangible Assets Accumulated Amortization Net Definite - lived Intangible Assets Trademarks ​ ​ ​ ​ $ 44,047 ​ $ (13,513) ​ $ 30,534 Customer relationships ​ ​ ​ ​ ​ 730,550 ​ ​ (146,192) ​ ​ 584,358 Non-compete ​ ​ ​ ​ ​ 7,719 ​ ​ (7,644) ​ ​ 75 Total ​ ​ ​ ​ $ 782,316 ​ $ (167,349) ​ $ 614,967 ​ The following table sets forth a breakout of our intangible assets as of December 31, 2021, in thousands: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Gross Definite - lived Intangible Assets Accumulated Amortization Net Definite - lived Intangible Assets Trademarks ​ ​ ​ ​ $ 44,365 ​ $ (8,161) ​ $ 36,204 Customer relationships ​ ​ ​ ​ ​ 731,759 ​ ​ (84,499) ​ ​ 647,260 Non-compete ​ ​ ​ ​ ​ 7,719 ​ ​ (6,974) ​ ​ 745 Total ​ ​ ​ ​ $ 783,843 ​ $ (99,634) ​ $ 684,209 ​ The following table sets forth the amortization expense related to the definite-lived intangible assets during each of the next five years, in thousands: ​ ​ ​ ​ ​ ​ Amortization Expense 2023 ​ $ 60,870 2024 ​ ​ 60,795 2025 ​ ​ 60,795 2026 ​ ​ 60,795 2027 ​ ​ 57,516 ​

Amendment No. 3 to Credit Agreement provides a provision that replaces LIBOR with SOFR and makes other conforming changes. ​ The following table outlines the key terms of the Credit Agreement (dollars in thousands): ​ ​ ​ ​ ​ Senior secured term loan facility $ 300,000 ​ Additional delayed draw term loan $ 300,000 ​ ​ ​ ​ ​ Additional term loan and/or revolver capacity available under incremental facility (a) $ 300,000 ​ ​ ​ ​ ​ Revolving facility $ 500,000 ​ Sublimit for issuance of letters of credit under revolving facility (b) $ 100,000 ​ Sublimit for swingline loans under revolving facility (b) $ 35,000 ​ ​ ​ ​ ​ Interest rate as of December 31, 2022 ​ 5.42 % Scheduled maturity date ​ 10/7/2026 ​ (a) Additional borrowing capacity is available under the incremental facility, subject to certain terms and conditions (including existing or new lenders providing commitments in respect of such additional borrowing capacity). (b) Use of the sublimits for the issuance of letters of credit and swingline loans reduces the availability under the revolving facility. ​ Interest payable on borrowings under the Credit Agreement is based on an applicable margin rate plus, at our option, either: ​ ● A base rate determined by reference to the highest of either (i) the federal funds rate plus 0.50 percent, (ii) BofA’s “prime rate,” and (iii) the SOFR rate for U.S. dollar deposits with a term of one month , plus 1.00 percent; or ​ ● A SOFR rate determined by reference to the costs of funds for deposits in U.S. dollars for the interest period relevant to such borrowings, subject to a floor of 0% . ​ The applicable margin rate is determined based on our Secured Leverage Ratio. In the case of base rate borrowings, the applicable margin rate ranges from 0.00 percent to 1.50 percent and in the case of SOFR rate borrowings, the applicable margin ranges from 1.00 percent to 2.50 percent. Borrowings under the Credit Agreement are prepayable at the Company’s option without premium or penalty. The Company is required to make prepayments with the net cash proceeds of certain asset sales and certain extraordinary receipts. ​ Revolving Facility ​ The Company has outstanding standby letters of credit that secure our financial obligations related to our workers’ compensation, general insurance, and auto liability programs. These standby letters of credit, as well as any outstanding amount borrowed under our revolving facility, reduce the availability under the revolving facility. The following table summarizes our availability under the revolving facility, in thousands: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of December 31, ​ 2022 2021 Revolving facility ​ $ 500,000 ​ $ 500,000 Less: standby letters of credit ​ ​ (67,689) ​ ​ (69,936) Availability under revolving facility ​ $ 432,311 ​ $ 430,064 ​ We are required to pay commitment fees to the Lenders in respect of any unutilized commitments. The commitment fees range from 0.15 percent to 0.275 percent per annum, depending on our Secured Leverage Ratio. We must also pay customary fees on outstanding letters of credit. ​ 3.625% Senior Notes ​ The 3.625% Senior Notes are $400.0 million senior unsecured obligations and bear interest at 3.625% per year, payable semiannually in arrears on March 15 and September 15, beginning on September 15, 2021. The 3.625% Senior Notes mature on March 15, 2029, unless redeemed early or repurchased. If we undergo a change in control, we must make an offer to repurchase all of the 3.625% Senior Notes then outstanding at a repurchase price equal to 101% of their aggregate principal amount, plus accrued and unpaid interest (if any) to, but not including, the repurchase date. ​ The Company may redeem the 3.625% Senior Notes, in whole or in part, at any time on or after March 15, 2024 at the redemption prices specified in the notes. The Company may also redeem all or part of the 3.625% Senior Notes at any time prior to March 15, 2024 at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus the Applicable Premium (as defined in the notes), as of, and accrued and unpaid interest to, the redemption date. Additionally, the Company may redeem up to 40% of the aggregate principal amount of the 3.625% Senior Notes prior to March 15, 2024 with the net cash proceeds of certain sales of its capital stock at 103.625% of the principal amount of the notes, plus accrued and unpaid interest, if any, to the date of redemption only if, after the redemption, at least 60% of the aggregate principal amount of the notes originally issued remains outstanding. ​ 4.125% Senior Notes ​ The 4.125% Senior Notes are $500.0 million senior unsecured obligations and bear interest at 4.125% per year, payable semiannually in arrears on February 15 and August 15, beginning on August 15, 2022. The 4.125% Senior Notes mature on February 15, 2032, unless redeemed early or repurchased. If we undergo a change in control, we must make an offer to repurchase all of the 4.125% Senior Notes then outstanding at a repurchase price equal to 101% of their aggregate principal amount, plus accrued and unpaid interest (if any) to, but not including, the repurchase date. ​ The Company may redeem the 4.125% Senior Notes, in whole or in part, at any time on or after October 15, 2026 at the redemption prices specified in the notes plus accrued and unpaid interest if redeemed during the 12 month period commencing on October 15 of the years set for: 2026 – 102.063%, 2027 – 101.375%, 2028 – 100.688%, 2029 and thereafter – 100.000%. The Company may also redeem a make-whole redemption of the 4.125% Senior Notes at any time prior to October 15, 2026 at the treasury rate plus 50 basis points. Additionally, the Company may redeem up to 40% of the aggregate principal amount of the 4.125% Senior Notes prior to October 15, 2024 with the net cash proceeds of certain sales of its capital stock at 104.125% of the principal amount of the notes, plus accrued and unpaid interest, if any, to the date of redemption only if, after the redemption, at least 60% of the aggregate principal amount of the notes originally issued remains outstanding. ​ Equipment Notes We did not issue equipment notes during the year ended December 31, 2022. The company issued $41.6 million of equipment notes for the purpose of financing the purchase of vehicles and equipment in prior years. The Company’s equipment notes each have a five year term maturing from 2023 to 2024 and bear interest at fixed rates between 2.8% and 4.4% . ​ Covenant Compliance The indentures governing our 3.625% Senior Notes and our 4.125% Senior Notes (together, our “Senior Notes”) contain restrictive covenants that, among other things, generally limit the ability of the Company and certain of its subsidiaries (subject to certain exceptions) to (i) create liens, (ii) pay dividends, acquire shares of capital stock and make payments on subordinated debt, (iii) place limitations on distributions from certain subsidiaries, (iv) issue or sell the capital stock of certain subsidiaries, (v) sell assets, (vi) enter into transactions with affiliates and (vii) effect mergers. The indentures provide for customary events of default which include (subject in certain cases to customary grace and cure periods), among others: nonpayment of principal or interest; breach of covenants or other agreements in the indenture; defaults in failure to pay certain other indebtedness; and certain events of bankruptcy or insolvency. Generally, if an event of default occurs and is continuing under the indenture, the trustee or the holders of at least 30% in aggregate principal amount of each of our Senior Notes then outstanding may declare the principal of, premium, if any, and accrued interest on the Senior Notes subject to such declaration immediately due and payable. The Senior Notes and related guarantees have not been registered under the Securities Act of 1933, and we are not required to register either the Senior Notes or the guarantees in the future. ​ The Credit Agreement contains certain covenants that limit, among other things, the ability of the Company to incur additional indebtedness or liens; to make certain investments or loans; to make certain restricted payments; to enter into consolidations, mergers, sales of material assets, and other fundamental changes; to transact with affiliates; to enter into agreements restricting the ability of subsidiaries to incur liens or pay dividends; or to make certain accounting changes. The Credit Agreement contains customary affirmative covenants and events of default. ​ The Credit Agreement requires that we maintain a Net Leverage Ratio and minimum Interest Coverage Ratio throughout the term of the agreement. The following table outlines the key financial covenants effective for the period covered by this Quarterly Report: ​ ​ ​ ​ ​ ​ As of December 31, 2022 Maximum Net Leverage Ratio ​ 3.50:1.00 Minimum Interest Coverage Ratio ​ 3.00:1.00 Compliance as of period end ​ In Compliance ​

Revenue Recognition	Revenue Recognition. Note 8 – Segment Information ​ We recognize revenue for our Installation segment over time as the related performance obligation is satisfied with respect to each particular order within a given customer’s contract. Progress toward complete satisfaction of the performance obligation is measured using a cost-to-cost measure of progress method. The cost input is based on the amount of material installed at that customer’s location and the associated labor costs, as compared to the total expected cost for the particular order. The total expected cost is a significant estimate in the revenue recognition process, requires judgment, and is subject to variability throughout the duration of the contract as a result of contract modifications and other circumstances impacting job completion. Generally, this results in revenue being recognized as the customer is able to receive and utilize the benefits provided by our services. Each contract contains one or more individual orders, which are based on services delivered. When material and installation services are bundled in a contract, we combine these items into one performance obligation as the overall promise is to transfer the combined item. ​ Revenue from our Specialty Distribution segment is recognized when title to products and risk of loss transfers to our customers. This represents the point in time when the customer is able to direct the use of and obtain substantially all the benefits from the product. The determination of when control is deemed transferred depends on the shipping terms that are agreed upon in the contract. ​ At time of sale, we record estimated reductions to revenue for customer programs and incentive offerings, including special pricing and other volume-based incentives based on historical experience, which is continuously adjusted. The duration of our contracts with customers is relatively short, generally less than a 90-day period, therefore there is not a significant financing component when considering the determination of the transaction price which gets allocated to the individual performance obligations, generally based on standalone selling prices. Additionally, we consider shipping costs charged to a customer as a fulfillment cost rather than a promised service and expense as incurred. Sales taxes, when incurred, are recorded as a liability and excluded from revenue on a net basis. ​ We record a contract asset when we have satisfied our performance obligation prior to billing and a contract liability when a customer payment is received prior to the satisfaction of our performance obligation. The difference between the beginning and ending balances of our contract assets and liabilities primarily results from the timing of our performance and the customer’s payment. See Note 3 – Revenue Recognition .

Receivables, net	Receivables, net.
Inventories, net	Inventories, net. ​ Inventory provisions are recorded to reduce inventory to the lower of cost or net realizable value for obsolete or slow moving inventory based on assumptions about future demand and marketability of products, the impact of new product introductions, inventory levels and turns, product spoilage, and specific identification of items such as product discontinuance, engineering/material changes, or regulatory-related changes. Our inventory reserve balances were $17.3 million and $11.2 million as of December 31, 2022 and 2021, respectively. As of December 31, 2022, and 2021, primarily all inventory consisted of finished goods. ​
Property and Equipment, net	Property and Equipment, net. ​ We review our property and equipment as an event occurs or circumstances change that would more likely than not reduce the fair value of the property and equipment below the carrying amount. If the carrying amount is not recoverable from its undiscounted cash flows, we would recognize an impairment loss for the difference between the carrying amount and the current fair value. Further, we evaluate the remaining useful lives of property and equipment at each reporting period to determine whether events and circumstances warrant a revision to the remaining depreciation periods.
Depreciation	Depreciation. ​ Asset Class Estimated Useful Life Buildings and land improvements 20 – 40 years Software 3 – 6 years Company vehicles 3 – 8 years Equipment 6 – 10 years ​
Leases	Leases ​ Lease payments are recognized as an expense in the consolidated statements of operations on a straight-line basis over the lease term, including future option periods the Company reasonably expects to exercise, whereby an equal amount of rent expense is attributed to each period during the term of the lease, regardless of when actual payments are made. This generally results in rent expense in excess of cash payments during the early years of a lease and rent expense less than cash payments in later years. The difference between rent expense recognized and actual rental payments is typically represented as the spread between the ROU asset and lease liability. ​ We recognize a ROU asset and a lease liability at the lease commencement date. Our leases may include options to extend or terminate the lease, which will be reflected in the calculation of the lease liability and corresponding ROU asset when it is reasonably certain that we will exercise that option. We do not recognize ROU assets and lease liabilities for short-term leases that have an initial lease term of 12 months or less. We recognize the lease payments associated with short-term leases as an expense on a straight-line basis over the lease term. ​ The lease liability is initially measured as the present value of the unpaid lease payments as of the lease commencement date. The lease liability is discounted based on our IBR at the time of modification for an existing lease or at the time of lease commencement for new leases. Our IBR includes significant assumptions regarding our secured borrowing rates obtained on equipment note issuances and adjustments for differences in the remaining lease term, underlying assets and market conditions for companies with similar credit qualities as well as interest rate index fluctuations. The ROU asset is initially measured at cost, which comprises the initial amount of the lease liability adjusted for lease payments made at or before the lease commencement date, plus any initial direct costs incurred less any lease incentives received. The ROU asset is subsequently measured throughout the lease term as the carrying amount of the lease liability, plus initial direct costs, plus (minus) any prepaid (accrued) lease payments, less the unamortized balance of lease incentives received. Certain vehicle lease agreements have residual value guarantees at the end of the lease which require us to return the asset with a specified percentage of the original or other calculated value. ​
Fair Value	Fair Value ​ Level 1: Quoted prices in active markets for identical assets or liabilities. ​ Level 2: Observable inputs other than Level 1 prices, such as quoted market prices for similar assets or liabilities or other inputs that are observable or can be corroborated by market data. ​ Level 3: Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions. ​
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets. ​ Fair value for our reporting units is determined using a discounted cash flow method, which includes significant unobservable inputs (Level 3 inputs). Using the discounted cash flow method requires us to make significant estimates and assumptions, including long term projections of cash flows, market conditions, and appropriate discount rates. Our judgments are based upon historical experience, current market trends, consultations with external valuation specialists and other information. In estimating future cash flows, we rely on internally generated long-range forecasts for sales and operating profits, including capital expenditures. ​ Intangible assets with finite useful lives are amortized using the straight-line method over their estimated useful lives. We evaluate the remaining useful lives of amortizable intangible assets at each reporting period to determine whether events and circumstances warrant a revision to the remaining periods of amortization.

Income Taxes	Income Taxes. ​ Valuation allowances are established against deferred tax assets when it is more likely than not that the realization of those deferred tax assets will not occur. In evaluating our ability to recover our deferred tax assets within the jurisdiction from which they arise, we consider all available positive and negative evidence. If, based upon all available evidence, both positive and negative, it is more likely than not (more than 50 percent likely) such deferred tax assets will not be realized, a valuation allowance is recorded. Significant weight is given to positive and negative evidence that is objectively verifiable. ​ Only those income tax positions that have a greater than 50 percent likelihood of being sustained upon examination by taxing authorities are recognized. There is an increased potential for volatility in our effective tax rate because of future changes in the income tax environment and the inherent complexities of income tax law in the various jurisdictions. Accordingly, provisions for tax-related matters, including interest and penalties, could be recorded in income tax expense in the period revised assessments are made. ​
