NOTE 1 — SIGNIFICANT ACCOUNTING POLICIES
Principles of Consolidation
As used in this report, the term “Company,” except as otherwise indicated by the context, means Lincoln Electric Holdings, Inc. and its wholly-owned and majority-owned subsidiaries for which it has a controlling interest.
The consolidated financial statements include the accounts of all legal entities in which the Company holds a controlling interest. The Company is also considered to have a controlling interest in a variable interest entity (“VIE”) if the Company determines it is the primary beneficiary of the VIE. Investments in legal entities in which the Company does not own a majority interest but has the ability to exercise significant influence over operating and financial policies are accounted for using the equity method.
The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, these unaudited consolidated financial statements do not include all of the information and notes required by GAAP for complete financial statements. However, in the opinion of management, these unaudited consolidated financial statements contain all the adjustments (consisting of normal recurring accruals) considered necessary to present fairly the financial position, results of operations and cash flows for the interim periods. Operating results for the six months ended June 30, 2019 are not necessarily indicative of the results to be expected for the year ending December 31, 2019.
The accompanying Consolidated Balance Sheet at December 31, 2018 has been derived from the audited financial statements at that date, but does not include all of the information and notes required by GAAP for complete financial statements. For further information, refer to the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018.
New Accounting Pronouncements:
This section provides a description of new accounting pronouncements ("Accounting Standard Update" or "ASU") issued by the Financial Accounting Standards Board ("FASB") that are applicable to the Company.
The following ASUs were adopted as of January 1, 2019:

Standard | Description
ASU No. 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220), issued February 2018. | ASU 2018-02 allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the U.S. Tax Cuts and Jobs Act (the "U.S. Tax Act"). The ASU only applies to the income tax effects of the U.S. Tax Act; all other existing guidance remains the same. The Company has elected not to reclassify the income tax effects of the U.S. Tax Act from Accumulated other comprehensive loss to Retained earnings.
ASU No. 2016-02, Leases (Topic 842), issued February 2016 | ASU 2016-02 ("Topic 842") aims to increase transparency and comparability among organizations by recognizing a right-of-use asset and lease liability on the balance sheet for all leases with a lease term greater than twelve months. Topic 842 also requires the disclosure of key information about leasing agreements. The Company adopted Topic 842 using the modified retrospective transition option of applying the new standard at the adoption date. The Company also elected the package of practical expedients, which among other things, allows it to not reassess the identification, classification and initial direct costs of leases commencing before the effective date of Topic 842. Refer to Note 10 to the consolidated financial statements for further details.

The Company is currently evaluating the impact on its financial statements of the following ASUs:

Standard | Description
ASU No. 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20), issued August 2018. | ASU 2018-14 modifies disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. The ASU also requires an entity to disclose the weighted-average interest crediting rates for cash balance plans and to explain the reasons for significant gains and losses related to changes in the benefit obligation. The ASU is effective January 1, 2020 and early adoption is permitted.
ASU No. 2018-13, Fair Value Measurement (Topic 944), issued August 2018. | ASU 2018-13 eliminates, amends and adds disclosure requirements related to fair value measurements. The ASU impacts various elements of fair value disclosure, including but not limited to, changes in unrealized gains or losses, significant unobservable inputs and measurement uncertainty. The ASU is effective January 1, 2020 and early adoption is permitted.
ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326), issued June 2016. | ASU 2016-13 requires that an entity measure impairment of certain financial instruments, including trade receivables, based on expected losses rather than incurred losses. The ASU is effective January 1, 2020 and early adoption is permitted.

NOTE 2 — REVENUE RECOGNITION
The following table presents the Company's Net sales disaggregated by product line:

|  | Three Months Ended June 30, |  | Six Months Ended June 30,
|  | 2019 |  | 2018 |  | 2019 |  | 2018
Consumables |  | $ | 444,850 |  |  | $ | 461,040 |  |  | $ | 887,808 |  |  | $ | 902,931 |
Equipment |  | 332,158 |  |  | 329,012 |  |  | 648,374 |  |  | 644,817 |
Net sales |  | $ | 777,008 |  |  | $ | 790,052 |  |  | $ | 1,536,182 |  |  | $ | 1,547,748 |

Consumable sales consist of electrodes, fluxes, specialty welding consumables and brazing and soldering alloys. Equipment sales consist of arc welding power sources, welding accessories, fabrication, plasma cutters, wire feeding systems, robotic welding packages, integrated automation systems, automation components, fume extraction equipment, CNC plasma and oxy-fuel cutting systems and regulators and torches used in oxy-fuel welding, cutting and brazing. Consumable and Equipment products are sold within each of the Company’s operating segments.
Substantially all of the Company's sales arrangements are short-term in nature involving a single performance obligation. The Company recognizes revenue when the performance obligation is satisfied and control of the product is transferred to the customer based upon shipping terms.
Within the Equipment product line, there are certain customer contracts related to automation products that may include multiple performance obligations. For such arrangements, the Company allocates revenue to each performance obligation based on its relative standalone selling price. The Company generally determines the standalone selling price based on the prices charged to customers or using expected cost plus margin. In addition, certain customized automation performance obligations within the Equipment product line, are accounted for over time. Under this method, revenue recognition is primarily based upon the ratio of costs incurred to date compared with estimated total costs to complete. The cumulative impact of revisions to total estimated costs is reflected in the period of the change, including anticipated losses. Less than 10% of the Company's Net sales are recognized over time.
At June 30, 2019, the Company recorded $20,730 related to advance customer payments and $8,752 related to billings in excess of revenue recognized. These contract liabilities are included in Other current liabilities in the Condensed Consolidated Balance Sheets. At December 31, 2018, the balances related to advance customer payments and billings in excess of revenue recognized were $17,023 and $17,013, respectively. Substantially all of the Company’s contract liabilities are recognized within twelve months based on contract duration. The Company records an asset for contracts where it has recognized revenue, but has not yet invoiced the customer for goods or services. At June 30, 2019 and December 31, 2018, $32,705 and $25,032, respectively, related to these future customer receivables was included in Other current assets in the Condensed Consolidated Balance Sheets. Contract asset amounts are expected to be billed within the next twelve months.

NOTE 6 — RATIONALIZATION AND ASSET IMPAIRMENTS
The Company recorded rationalization and asset impairment net charges of $4,842 in the six months ended June 30, 2019. The 2019 charges are primarily related to employee severance, asset impairments and gains or losses on the disposal of assets.
During 2019, the Company initiated rationalization plans within International Welding. The plans include headcount restructuring and the consolidation of manufacturing operations to better align the cost structure with economic conditions and operating needs. At June 30, 2019, liabilities of $1,583 were recognized in Other current liabilities in the Company's Condensed Consolidated Balance Sheet.
During 2018, the Company initiated rationalization plans within International Welding. The plans include headcount restructuring and the consolidation of manufacturing operations to better align the cost structure with economic conditions and operating needs. At June 30, 2019, liabilities of $1,553 were recognized in Other current liabilities in the Company's Condensed Consolidated Balance Sheet.
The Company believes the rationalization actions will positively impact future results of operations and will not have a material effect on liquidity and sources and uses of capital. The Company continues to evaluate its cost structure and additional rationalization actions may result in charges in future periods.

At June 30, 2019 and December 31, 2018, approximately 36% and 37%, respectively, of total inventories were valued using the last-in, first-out ("LIFO") method. The excess of current cost over LIFO cost was $78,760 and $79,626 at June 30, 2019 and December 31, 2018, respectively.
NOTE 10 — LEASES
On January 1, 2019, the Company adopted Topic 842 using the modified retrospective transition option. The adoption of Topic 842 resulted in the recording of right-of-use assets and lease liabilities for the Company's operating leases. The table below summarizes the right-of-use assets and lease liabilities in the Company's Condensed Consolidated Balance sheets:

Operating Leases | Balance Sheet Classification | June 30, 2019
Right-of-use assets | Other assets | $ | 58,363 |
Current liabilities | Other current liabilities | $ | 14,362 |
Noncurrent liabilities | Other liabilities | 44,326 |
Total lease liabilities |  | $ | 58,688 |

Topic 842 did not materially impact our consolidated net earnings, cash flows or debt covenants.
The Company determines if an agreement is a lease at inception. Right-of-use assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. As most of the Company’s operating leases do not provide an implicit rate, the Company uses a discount rate based on information available at commencement date to present value the lease payments.
The Company has operating leases for sales offices, manufacturing facilities, warehouses and distribution centers, transportation equipment, office equipment and information technology equipment. Some of these leases are noncancelable. Variable or short term lease costs contained within the Company’s operating leases are not material. Most leases include one or more options to renew, which can extend the lease term from 1 year to 11 years or more. The exercise of lease renewal options is at the Company's sole discretion. Certain leases also include options to purchase the leased property. Leases with an initial term of 12 months or less are not recorded on the Company's Condensed Consolidated Balance sheets. The Company recognizes lease expense for these leases on a straight-line basis over the lease term.
The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise. The Company's lease agreements do not contain any material residual value guarantees or material restrictive covenants.
Total lease expense, which is included in Cost of goods sold and Selling, general and administrative expenses in the Company's Consolidated Statements of Income, was $6,546 and $12,435 in the three and six months ended June 30, 2019, respectively. Cash paid for amounts included in the measurement of lease liabilities for the three and six months ended June 30, 2019 respectively was $4,549 and $9,233 and is included in Net cash provided by operating activities in the Company's Consolidated Statements of Cash Flows. Right-of-use assets obtained in exchange for operating lease liabilities during the three and six months ended June 30, 2019 were $9,717 and $14,673, respectively.

NOTE 12 — DEBT
Revolving Credit Agreement
The Company has a line of credit totaling $400,000 through the Amended and Restated Credit Agreement (the “Credit Agreement”). The Credit Agreement has a term of 5 years and may be increased, subject to certain conditions, by an additional amount up to $100,000. The interest rate on borrowings is based on either the London Inter-Bank Offered Rate ("LIBOR") or the prime rate, plus a spread based on the Company’s leverage ratio, at the Company’s election. The Company amended and restated the Credit Agreement on June 30, 2017, extending the maturity of the line of credit to June 30, 2022. The Credit Agreement contains customary affirmative, negative and financial covenants for credit facilities of this type, including limitations on the Company and its subsidiaries with respect to liens, investments, distributions, mergers and acquisitions, dispositions of assets, transactions with affiliates and a fixed charges coverage ratio and total leverage ratio. As of June 30, 2019, the Company was in compliance with all of its covenants and had $30,000 of outstanding borrowings under the Credit Agreement.
Senior Unsecured Notes
On April 1, 2015 and October 20, 2016, the Company entered into separate Note Purchase Agreements pursuant to which it issued senior unsecured notes (the "Notes") through a private placement. The 2015 Notes and 2016 Notes each have an aggregate principal amount of $350,000, comprised of four different series ranging from $50,000 to $100,000, with maturity dates ranging from August 20, 2025 through April 1, 2045, and interest rates ranging from 2.75% and 4.02%. Interest on the Notes is paid semi-annually. The Company's total weighted average effective interest rate and remaining weighted average tenure of the Notes is 3.3% and 15 years, respectively. The proceeds of the Notes were used for general corporate purposes. The Notes contain certain affirmative and negative covenants. As of June 30, 2019, the Company was in compliance with all of its debt covenants relating to the Notes.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS (Continued)
Dollars in thousands, except per share amounts
The decrease in the effective tax rate for the six months ended June 30, 2019, as compared with the same period in 2018, was primarily due to income tax benefits for the settlement of a tax item as well as tax deductions associated with an investment in a subsidiary in 2019, rationalization charges in regions with low or no tax benefit recorded in 2018 and adjustments and incremental tax expense recorded in 2018 related to the U.S. Tax Act.
As of June 30, 2019, the Company had $26,157 of unrecognized tax benefits. If recognized, approximately $22,597 would be reflected as a component of income tax expense.
The Company files income tax returns in the U.S. and various state, local and foreign jurisdictions. With few exceptions, the Company is no longer subject to U.S. federal, state and local or non-U.S. income tax examinations by tax authorities for years before 2014. The Company is currently subject to U.S., various state and non-U.S. income tax audits.
Unrecognized tax benefits are reviewed on an ongoing basis and are adjusted for changing facts and circumstances, including progress of tax audits and closing of statutes of limitations. Based on information currently available, management believes that additional audit activity could be completed and/or statutes of limitations may close relating to existing unrecognized tax benefits. It is reasonably possible there could be a reduction of $5,379 in previously unrecognized tax benefits by the end of the second quarter 2020.
NOTE 16 — DERIVATIVES
The Company uses derivative instruments to manage exposures to currency exchange rates, interest rates and commodity prices arising in the normal course of business. Both at inception and on an ongoing basis, the derivative instruments that qualify for hedge accounting are assessed as to their effectiveness, when applicable. Hedge ineffectiveness was immaterial in the six months ended June 30, 2019 and 2018.

2019 and December 31, 2018. The fair value of long-term debt at June 30, 2019 and December 31, 2018, including the current portion, was approximately $704,319 and $649,714, respectively, which was determined using available market information and methodologies requiring judgment. The carrying value of this debt at such dates was $710,568 and $702,660, respectively. Since judgment is required in interpreting market information, the fair value of the debt is not necessarily the amount that could be realized in a current market exchange.
The Company has various financial instruments, including cash and cash equivalents, short and long-term debt and forward contracts. While these financial instruments are subject to concentrations of credit risk, the Company has minimized this risk by entering into arrangements with a number of major banks and financial institutions and investing in several high-quality instruments. The Company does not expect any counterparties to fail to meet their obligations.

Lincoln Electric Holdings, Inc. |  |  |  |  | (4.4 | %) |  | 3.0 | % |  | 3.1 | % |  | (2.4 | %) |  | (0.7 | %)

Net sales were flat in the three and six months ended June 30, 2019 primarily as a result of acquisitions, offset by lower organic sales and unfavorable foreign exchange. The increase in Net sales from acquisitions was driven by the acquisitions of Coldwater, Pro Systems, Inovatech and Baker within Americas Welding and Worthington within The Harris Products Group.
Gross Profit:
Gross profit for the three and six months ended June 30, 2019 increased, as a percent of sales, compared to the prior year due to price management and segment mix. The three and six months ended June 30, 2019 includes a last-in, first-out ("LIFO") credit of $886 and $865, respectively, as compared to a LIFO charge of $5,261 and $6,173, respectively, in the three and six months ended June 30, 2018.
Selling, General & Administrative ("SG&A") Expenses:
The decrease in SG&A expenses for the three and six months ended June 30, 2019 as compared to June 30, 2018 is due to favorable foreign exchange and lower compensation costs, partially offset by higher expense from acquisitions.
Rationalization and Asset Impairment Charges:
The Company recorded net charges of $1,307, $937 after-tax, and $4,842, $3,751 after-tax, in the three and six months ended June 30, 2019, respectively, primarily related to severance, asset impairments and gains or losses on the disposal of assets. The Company recorded net charges of $11,542, $10,362 after-tax, and $21,717, $18,232 after-tax, in the three and six months ended June 30, 2018, respectively, primarily related to employee severance and asset impairment charges.
Interest Expense, Net:
The increase in Interest expense, net for the three and six months ended June 30, 2019 as compared to June 30, 2018 was due to lower interest income on marketable securities.
Income Taxes:
The effective tax rate was lower for the three and six months ended June 30, 2019 as compared to June 30, 2018 primarily due to income tax benefits for the settlement of a tax item as well as tax deductions associated with an investment in a subsidiary in 2019, rationalization charges in regions with low or no tax benefit recorded in 2018 and adjustments and incremental tax expense recorded in 2018 related to the U.S. Tax Cuts and Job Act (the "U.S. Tax Act").
Net Income:
The increase in Net income for the three and six months ended June 30, 2019 as compared to June 30, 2018 was primarily due to a lower effective tax rate and lower rationalization and asset impairment charges.

EBIT is defined as Operating income plus Other income (expense). EBIT is adjusted for special items as determined by management such as the impact of rationalization activities, certain asset impairment charges and gains or losses on disposals of assets.

Non-GAAP Financial Measures
The Company reviews Adjusted operating income, Adjusted net income, Adjusted EBIT, Adjusted effective tax rate, Adjusted diluted earnings per share and Return on invested capital, all non-GAAP financial measures, in assessing and evaluating the Company's underlying operating performance. These non-GAAP financial measures exclude the impact of special items on the Company's reported financial results. Non-GAAP financial measures should be read in conjunction with the generally accepted accounting principles in the United States ("GAAP") financial measures, as non-GAAP measures are a supplement to, and not a replacement for, GAAP financial measures.
The following table presents the reconciliations of Operating income as reported to Adjusted operating income, Net income as reported to Adjusted net income and Adjusted EBIT, Effective tax rate as reported to Adjusted effective tax rate and Diluted earnings per share as reported to Adjusted diluted earnings per share:

Liquidity and Capital Resources
The Company’s cash flow from operations can be cyclical. Operational cash flow is a key driver of liquidity, providing cash and access to capital markets. In assessing liquidity, the Company reviews working capital measurements to define areas for improvement. Management anticipates the Company will be able to satisfy cash requirements for its ongoing businesses for the foreseeable future primarily with cash generated by operations, existing cash balances, borrowings under its existing credit facilities and raising debt in capital markets.
The Company continues to expand globally and periodically looks at transactions that would involve significant investments. The Company can fund its global expansion plans with operational cash flow, but a significant acquisition may require access to capital markets, in particular, the long-term debt market, as well as the syndicated bank loan market. The Company’s financing strategy is to fund itself at the lowest after-tax cost of funding. Where possible, the Company utilizes operational cash flows and raises capital in the most efficient market, usually the United States, and then lends funds to the specific subsidiary that requires funding. If additional acquisitions providing appropriate financial benefits become available, additional expenditures may be made.
The following table reflects changes in key cash flow measures:

| Six Months Ended June 30,
| 2019 |  | 2018 |  | $ Change
Cash provided by operating activities (1) | $ | 151,985 |  |  | $ | 123,558 |  |  | $ | 28,427 |

Cash dividends paid to shareholders | (60,101 | ) |  | (51,250 | ) |  | (8,851 | )
(Decrease) increase in Cash and cash equivalents (4) | (168,988 | ) |  | 30,393 |  |  |

(1) Cash provided by operating activities increased for the six months ended June 30, 2019, compared with the six months ended June 30, 2018 primarily due to improved Company performance and cash flows from tax payments and receipts.
(2) Cash used by investing activities increased for the six months ended June 30, 2019, compared with the six months ended June 30, 2018 predominantly due to cash used in the acquisition of businesses in 2019 and net proceeds from marketable securities in 2018. The Company currently anticipates capital expenditures of $65,000 to $75,000 in 2019. Anticipated capital expenditures include investments for capital maintenance to improve operational effectiveness. Management critically evaluates all proposed capital expenditures and expects each project to increase efficiency, reduce costs, promote business growth or improve the overall safety and environmental conditions of the Company’s facilities.
(3) Cash used by financing activities increased in the six months ended June 30, 2019, compared with the six months ended June 30, 2018 due to higher purchases of common shares for treasury.
(4) Cash and cash equivalents decreased 47.1%, or $168,988, to $189,861 during the six months ended June 30, 2019, from $358,849 as of December 31, 2018. This decrease was predominantly due to cash used in the acquisition of

businesses, purchases of common shares for treasury and cash dividends paid to shareholders, partially offset by cash provided by operating activities. The decrease in Cash and cash equivalents during the six months ended June 30, 2019 compares to an increase of 9.3% during the six months ended June 30, 2018. The increase in 2018 was primarily due to cash provided by operating activities and proceeds from marketable securities, partially offset by cash dividends paid to shareholders. At June 30, 2019, $173,350 of Cash and cash equivalents was held by international subsidiaries.
The Company's total debt levels increased compared to December 31, 2018 predominately due to additional short term borrowings. Total debt to total invested capital increased to 46.7% at June 30, 2019 from 44.2% at December 31, 2018.
In July 2019, the Company paid a cash dividend of $0.47 per share, or $29,036, to shareholders of record as of June 28, 2019.

(1) Average operating working capital to net sales is defined as the sum of Accounts receivable and Inventories less Trade accounts payable as of period end divided by annualized rolling three months of Net sales.
Return on Invested Capital
The Company reviews return on invested capital ("ROIC") in assessing and evaluating the Company's underlying operating performance. ROIC is a non-GAAP financial measure that the Company believes is a meaningful metric to investors in evaluating the Company’s financial performance and may be different than the method used by other companies to calculate ROIC. ROIC is defined as rolling 12 months of Adjusted net income excluding tax-effected interest income and expense divided by invested capital. Invested capital is defined as total debt, which includes Short-term debt and Long-term debt, less current portions, plus Total equity.
ROIC for the twelve months ended June 30, 2019 and 2018 were as follows:

Forward-looking statements generally can be identified by the use of words such as “may,” “will,” “expect,” “intend,” “estimate,” “anticipate,” “believe,” “forecast,” “guidance” or words of similar meaning. Actual results may differ materially from such statements due to a variety of factors that could adversely affect the Company’s operating results.
