SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Our accounting policies conform to generally accepted accounting principles in the U.S. ("GAAP”) and are applied on a consistent basis among all years presented. Significant accounting policies are described below.

Principles of Consolidation

The consolidated financial statements include the accounts of Graybar and its subsidiary companies. All material intercompany balances and transactions have been eliminated. The ownership interests that are held by owners other than the Company in subsidiaries consolidated by the Company are accounted for and reported as noncontrolling interests.

Estimates

The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities. Actual results could differ from these estimates.

Reclassifications

Certain reclassifications have been made to prior years' financial information to conform to the December 31, 2018 presentation. These changes consisted of reclassifying certain asset and liability items between current and non-current within the December 31, 2017 balance sheet. The reclassifications had no effect on total assets or liabilities as of December 31, 2017.

Subsequent Events

We have evaluated subsequent events through the time of the filing of this Annual Report on Form 10-K with the Commission. No material subsequent events have occurred since December 31, 2018 that require recognition or disclosure in our financial statements.

Revenue Recognition

Sales revenue is recognized when performance obligations are satisfied, which is typically upon delivery of the product to the customer. Sometimes product is purchased from the manufacturer and drop-shipped to the customer. We generally take control of the goods when shipped by the manufacturer and then recognize revenue when control of the product transfers to the customer. Revenues recognized are primarily for product sales, but may also include freight and handling charges. Our standard warehouse shipping terms are FOB shipping point, under which control passes to the customer at the time of shipment. We also earn revenue for professional services, general contracting services, and storage services. Service revenue represented less than 1% of gross sales for the year ended December 31, 2018. Revenue is reported net of all taxes assessed by governmental authorities as a result of revenue-producing transactions, primarily sales tax.

Outgoing Freight Expenses

We record certain outgoing freight expenses as a component of selling, general and administrative expenses. These costs totaled $62.0 million, $54.5 million, and $50.9 million for the years ended December 31, 2018, 2017, and 2016, respectively.

Cash and Cash Equivalents

We account for cash on hand, deposits in banks, and other short-term, highly liquid investments with an original maturity of three months or less as cash and cash equivalents.

Allowance for Doubtful Accounts

We perform ongoing credit evaluations of our customers, and a significant portion of our trade receivables is secured by mechanic’s lien or payment bond rights. We maintain allowances to reflect the expected uncollectability of trade receivables based on past collection history and specific risks identified in the receivables portfolio. Although actual credit losses have historically been within management’s expectations, additional allowances may be required if the financial condition of our customers were to deteriorate.

Merchandise Inventory

Our inventory is stated at the lower of cost (generally determined using the last-in, first-out (“LIFO”) cost method) or market. LIFO accounting is a method of accounting that, compared with other inventory accounting methods, generally provides better matching of current costs with current sales.

We make provisions for obsolete or excess inventories as necessary to reflect reductions in inventory value.

Vendor Allowances

Our agreements with many of our suppliers provide for us to earn volume incentives based on purchases during the agreement period. Based on the provisions of our vendor agreements, we develop vendor accrual rates by estimating the point at which we will have completed our performance under the agreement and the deferred amounts will be earned. We perform analyses and review historical trends to ensure the deferred amounts earned are appropriately recorded. Certain vendor agreements contain purchase volume incentives that provide for increased funding when graduated purchase volumes are met. Amounts accrued throughout the year are based on estimates of future activity levels, and could be materially impacted if actual purchase volumes differ. Changes in the estimated amount of incentives are treated as changes in estimate and are recognized in earnings in the period in which the change in estimate occurs. In the event that the operating performance of our suppliers were to decline, however, there can be no assurance that amounts earned would be paid or that the volume incentives would continue to be included in future agreements.

Property and Depreciation

Property, plant and equipment are recorded at cost. Depreciation is expensed on a straight-line basis over the estimated useful lives of the related assets. Interest costs incurred to finance expenditures for major long-term construction projects are capitalized as part of the asset's historical cost and included in property, plant and equipment, then depreciated over the useful life of the asset. Leasehold improvements are amortized over the term of the lease or the estimated useful life of the improvement, whichever is shorter. Expenditures for maintenance and repairs are charged to expense when incurred, while the costs of significant improvements, which extend the useful life of the underlying asset, are capitalized.

Credit Risk

Financial instruments that potentially expose us to concentrations of credit risk consist primarily of trade receivables. We perform ongoing credit evaluations of our customers, and a significant portion of our trade receivables are secured by mechanic’s lien or payment bond rights. We maintain allowances for potential credit losses, and such losses historically have been within management’s expectations.

Fair Value

We endeavor to utilize the best available information in measuring fair value. GAAP has established a fair value hierarchy, which prioritizes the inputs used in measuring fair value. The tiers in the hierarchy include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs for which little or no market data exists, therefore requiring an entity to develop its own data inputs and assumptions. We have used fair value measurements to value our pension plan assets.

Foreign Currency Exchange Rate

The functional currency for our Canadian subsidiary is the Canadian dollar. Accordingly, its balance sheet amounts are translated at the exchange rates in effect at the end of each reporting period and its statements of income amounts are translated at the average rates of exchange prevailing during the current period. Currency translation adjustments are included in accumulated other comprehensive loss.

Goodwill

Our goodwill is not amortized, but rather tested annually for impairment. Goodwill is reviewed annually in the fourth quarter and when circumstances or other events might indicate that impairment may have occurred. We first perform a qualitative assessment of goodwill impairment. The qualitative assessment considers several factors including the excess fair value over carrying value as of the last quantitative impairment test, the length of time since the last fair value measurement, the current carrying value, market conditions, actual performance compared to forecasted performance, and the current business outlook. If the qualitative assessment indicates that it is more likely than not that goodwill is impaired, the reporting unit is then quantitatively tested for impairment. If a quantitative assessment is required, the fair value is determined using a variety of assumptions including estimated future cash flows of the reporting unit using applicable discount rates.

Definite Lived Intangible Assets

The cost of intangible assets with determinable useful lives is amortized to reflect the pattern of economic benefits consumed, either on a straight-line or accelerated basis over the estimated periods benefited. Customer relationships, trade names and other non-contractual intangible assets with determinable lives are amortized over periods generally ranging from 3 to 20 years. Intangible assets are tested for impairment if events or circumstances occur indicating that the respective asset might be impaired.

Income Taxes

We recognize deferred tax assets and liabilities to reflect the future tax consequences of events that have been recognized in the financial statements or tax returns. A deferred tax asset or liability results from the temporary difference between an item’s carrying value as reflected in the financial statements and its tax basis, and is calculated using enacted applicable tax rates. We assess the likelihood that our deferred tax assets will be recovered from future taxable income and, to the extent we believe that recovery is not likely, a valuation allowance is established. Changes in the valuation allowance, when recorded, are included in the provision for income taxes in the consolidated financial statements. We classify interest expense and penalties as part of our provision for income taxes based upon applicable federal and state interest/underpayment percentages. We assess uncertainty regarding tax positions taken in previously filed returns and record reserves in accordance with the guidance under Accounting Standards Codification ("ASC") 740-10, "Accounting for Uncertainty in Income Taxes".

Other Postretirement Benefits

We account for postretirement benefits other than pension by accruing the costs of benefits to be provided over the eligible employees’ periods of active service. These costs are determined on an actuarial basis. Our consolidated balance sheets reflect the funded status of postretirement benefits.

Pension Plan

We sponsor a noncontributory defined benefit pension plan accounted for by accruing the cost to provide the benefits over the eligible employees’ periods of active service. These costs are determined on an actuarial basis. Our consolidated balance sheets reflect the funded status of the defined benefit pension plan.

Non-Operating Expenses

Non-operating expenses are comprised of interest expense, net and non-service cost components of the net periodic benefit cost for the pension and other postretirement benefit plans. The non-service cost components include interest cost, expected return on plan assets, amortization of net actuarial gains/losses, and amortization of prior service costs/gains.

New Accounting Standards

No new accounting standards that were issued or became effective during 2018 have had or are expected to have a material impact on our consolidated financial statements except those noted below.

We adopted the Financial Accounting Standards Board ("FASB") Accounting Standards Update ("ASU" or "Update") 2017-07, "Compensation - Retirement Benefits (Topic 715)" ("ASU 2017-07") on January 1, 2018 using the retrospective transition method. The updates to the standard require us to report the service cost component in the same line as other compensation costs arising from services rendered by employees during the reporting period. The other components of net benefit costs are presented in the income statement separately from the service cost and outside of a subtotal of income from operations. As a result of the adoption, the financial statement line previously entitled "interest expense, net" was changed to "non-operating expenses". The impact to the operating results for the years ended December 31, 2017 and 2016 within the consolidated statements of income as a result of adopting ASU 2017-07 is presented in the tables below:

Consolidated Statements of Income



	Year Ended December 31, 2017
	As Reported		Reclassification			As Adjusted
Selling, general and administrative expenses	$	1,047.2	$	(20.6	)	$	1,026.6
Non-operating expenses	4.2		20.6			24.8



	Year Ended December 31, 2016
	As Reported		Reclassification			As Adjusted
Selling, general and administrative expenses	$	1,008.7	$	(22.4	)	$	986.3
Non-operating expenses	3.6		22.4			26.0

On January 1, 2018, we adopted ASC Topic 606, "Revenue from Contracts with Customers." See Note 3, "Revenue", for further information.

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)” ("ASU 2016-02"). The core principle of Topic 842 requires a lessee to recognize a right of use asset ("ROU") and lease liability on the balance sheet for both operating and finance leases while disclosing key information about the leasing arrangements. The amendments in ASU 2016-02 are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, using a modified retrospective approach.

We will adopt the new guidance on January 1, 2019. We will elect the package of transitional practical expedients which allows an entity not to reassess whether expired or existing contracts contain leases, lease classification of expired or existing leases, and whether previously capitalized initial direct costs would qualify for capitalization under Topic 842. As guidance allows, this package can be elected separate of any other practical expedient. As a practical expedient, the Company has elected as an accounting policy not to separate non-lease components from lease components for real estate properties and information technology.

In preparation for adoption of the standard, we have implemented internal controls and key system functionality to enable the preparation of financial information. The standard will have a material impact on our consolidated balance sheets, but will not have a material impact on our consolidated statements of income. The most significant impact will be the recognition of ROU assets and lease liabilities for operating leases, while our accounting for capital leases remains substantially unchanged.

Adoption of the ASU 2016-02 will result in the recognition of additional ROU assets and lease liabilities for operating leases of approximately $100 million at January 1, 2019.

In June 2016, the FASB issued ASU 2016-13, "Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments", which introduces new guidance for the accounting for credit losses on certain financial instruments. The amendments in this ASU are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted. We do not expect the adoption of this Update to have a material impact on our consolidated financial statements.

In August 2018, the FASB issued ASU 2018-13, "Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement" ("ASU 2018-13") that makes minor changes to the disclosure requirements on fair value measurements in Topic 820. The guidance eliminates requirements for certain disclosures that are no longer considered cost beneficial and adds new disclosure requirements that the FASB considers pertinent. ASU 2018-13 is effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. We are currently evaluating the impact of the adoption of the Update on our financial statements, but do not expect it to have a material impact.

In August 2018, the FASB issued ASU 2018-14, "Compensation-Retirement Benefits-Defined Benefit Plans-General (Subtopic 715-20): Disclosure Framework-Changes to the Disclosure Requirements for Defined Benefit Plans" ("ASU 2018-14") that makes minor changes to the disclosure requirements for employers that sponsor defined benefit pension and/or other postretirement benefit plans. The guidance eliminates requirements for certain disclosures that are no longer considered cost beneficial and adds new disclosure requirements that the FASB considers pertinent. ASU 2018-14 is effective for fiscal years ending after December 15, 2020 for public entities. Early adoption is permitted. We are currently evaluating the impact of the adoption of the Update on our financial statements, but do not expect it to have a material impact.

In August 2018, the FASB issued ASU 2018-15, "Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract" ("ASU 2018-15") requiring a customer in a cloud computing arrangement that is a service contract to follow the internal use software guidance in ASC 350-40 to determine which implementation costs to capitalize as assets. Capitalized implementation costs related to a hosting arrangement that is a service contract will be amortized over the term of the hosting arrangement, beginning when the module or component of the hosting arrangement is ready for its intended use. ASU 2018-15 is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years for public entities. Early adoption is permitted. The adoption of this Update will not have a material impact on our financial statements.
