Revolving Credit Facility

In June 2021, the Company entered into a $650 million unsecured revolving credit facility (the “Credit Agreement”). The Company incurred $1.9 million of costs in connection with this Credit Agreement. The 2021 Credit Agreement replaced an existing Fifth Amended and Restated Credit Agreement dated as of November 15, 2017. Under the new agreement, the Company’s revolving credit facility was increased from $550 million to $650 million. The credit facility has a five-year maturity, which may be extended up to two times for periods determined by the Company and the applicable extending lenders, and permits the Company to borrow in U.S. dollars, certain specified foreign currencies, and each other currency that may be approved in accordance with the 2021 Facility. The borrowings under the Credit Agreement bear interest at either a eurocurrency rate plus a margin between 1.0% and 1.625% or a base rate (as defined in the Credit Agreement) plus a margin of between 0% and 0.625%. The rates on March 31, 2022 and December 31, 2021 were 1.70% and 1.36%, respectively. Borrowings under this Credit Agreement are guaranteed by certain Company operating subsidiaries. Letters of credit commitments outstanding under this agreement aggregated to $44.5 million and $44.3 million at March 31, 2022 and December 31, 2021, respectively, which reduced borrowing limits available to the Company. Interest expense related to the Credit Agreement was $0.1 million and $0.1 million for the three months ended March 31, 2022 and March 31, 2021, respectively. There were no loan amounts outstanding under the Credit Agreement on March 31, 2022.  

Private Placement

On July 1, 2014, the Company finalized a private placement whereby the Company raised an aggregate amount of $250.0 million in debt as follows (in thousands):

Tranche	Debt Amount		Maturity Date	Interest Rates
Senior Note, Series A	$	50,000	July 15, 2021		4.44	%
Senior Note, Series B		100,000	July 15, 2024		4.98	%
Senior Note, Series C		60,000	July 15, 2026		5.13	%
Senior Note, Series D		40,000	July 15, 2029		5.38	%

The Company incurred $1.1 million of debt issuance costs in connection with the private placement. On August 10, 2018, the Company finalized an amended and restated intercreditor agreement related to this private placement to more closely align certain covenants and definitions with the terms under the 2017 amended and restated Credit Agreement and incurred $0.5 million of additional issuance costs. These costs are presented as a direct deduction from the debt on the face of the consolidated balance sheets.  Interest expense related to the Senior Notes for the three months ended March 31, 2022 and March 31, 2021 was $2.6 million and $3.2 million, respectively.  The amortization of debt issuance costs and interest expense is recorded in “Interest expense” on the consolidated statements of income. The Company paid the $50 million Series A tranche of the Senior Note as scheduled in July 2021. The Company made interest payments of $5.1 million and $6.2 million for the three months ended March 31, 2022 and March 31, 2021, respectively.  Interest payable of $2.2 million and $4.7 million is recorded in “Accrued expenses and other current liabilities” on the consolidated balance sheets at March 31, 2022 and December 31, 2021, respectively, related to the Senior Notes. 

Using a discounted cash flow technique that incorporates a market interest yield curve with adjustments for duration, optionality, and risk profile, the Company estimated that the fair value (Level 2) of its Senior Notes at March 31, 2022 approximates $208.4 million. See “Note 16 – Fair Value of Financial Instruments” for the definition of Level 2 of the fair value hierarchy.

The Credit Agreement and private placement includes various covenants, including restrictions on indebtedness, liens, acquisitions, investments or dispositions, payment of dividends and maintenance of certain financial ratios and conditions. The Company was in compliance with these covenants at March 31, 2022 and December 31, 2021.

The Company also has in place several secondary bank credit lines for issuing letters of credit, principally for foreign contracts, to support performance and completion guarantees. Letters of credit commitments outstanding under these bank lines aggregated $220.6 million and $223.0 million at March 31, 2022 and December 31, 2021, respectively.

Convertible Senior Notes

In August 2020, the Company issued an aggregate $400.0 million of 0.25% Convertible Senior Notes due 2025, including the exercise of a $50.0 million initial purchasers’ option. The Company received proceeds from the issuance and sale of the Convertible Senior Notes of $389.7 million, net of $10.3 million of transaction fees and other third-party offering expenses. The Convertible Senior Notes accrue interest at a rate of 0.25% per annum, payable semi-annually on February 15 and August 15 of each year beginning on February 15, 2021, and will mature on August 15, 2025, unless earlier repurchased, redeemed or converted.

The Convertible Senior Notes are the Company’s senior unsecured obligations and will rank senior in right of payment to any of the Company’s indebtedness that is expressly subordinated in right of payment to the Notes; equal in right of payment to any of the Company’s unsecured indebtedness that is not so subordinated; effectively junior in right of payment to any of the Company’s secured indebtedness, to the extent of the value of the assets securing such indebtedness; and structurally junior to all indebtedness and other liabilities (including trade payables) of the Company’s subsidiaries

Each $1,000 of principal of the Notes will initially be convertible into 22.2913 shares of our common stock, which is equivalent to an initial conversion price of $44.86 per share, subject to adjustment upon the occurrence of specified events. On or after March 15, 2025 until the close of business on the second scheduled trading day immediately preceding the maturity date of the Convertible Senior Notes, holders may convert all or a portion of their Convertible Senior Notes, regardless of the conditions below.

Prior to the close of business on the business day immediately preceding March 15, 2025, the Notes will be convertible at the option of the holders thereof only under the following circumstances:

• during any calendar quarter commencing after the calendar quarter ending on December 31, 2021, if the last reported sale price of the Company’s common stock for at least 20 trading days, whether or not consecutive, during a period of 30 consecutive trading days ending on, and including the last trading day of the immediately preceding calendar quarter, is greater than or equal to 130% of the conversion price on each applicable trading day;

• during the five business day period after any five consecutive trading day period in which, for each trading day of that period, the trading price per $1,000 principal amount of Convertible Senior Notes for such trading day was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such trading day;

• if the Company calls such Convertible Senior Notes for redemption; or

• upon the occurrence of specified corporate events described in the Indenture.

The Company may redeem all or any portion of the Convertible Senior Notes for cash, at its option, on or after August 21, 2023 and before the 51^st scheduled trading day immediately before the maturity date at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, but only if the last reported sale price per share of the Company’s common stock exceeds 130% of the conversion price for a specified period of time. In addition, calling any Convertible Senior Note for redemption will constitute a Make-Whole Fundamental Change with respect to that Convertible Senior Note, in which case the conversion rate applicable to the conversion of that Convertible Senior Note will be increased in certain circumstances if it is converted after it is called for redemption.

Upon the occurrence of a fundamental change prior to the maturity date of the Convertible Senior Notes, holders of the Convertible Senior Notes may require the Company to repurchase all or a portion of the Convertible Senior Notes for cash at a price equal to 100% of the principal amount of the Convertible Senior Notes to be repurchased, plus any accrued and unpaid interest to, but excluding, the fundamental change repurchase date.

Upon conversion, the Company may settle the Convertible Senior Notes for cash, shares of the Company’s common stock, or a combination thereof, at the Company’s option. If the Company satisfies its conversion obligation solely in cash or through payment and delivery of a combination of cash and shares of the Company’s common stock, the amount of cash and shares of common stock due upon conversion will be based on a daily conversion value calculated on a proportionate basis for each trading day in a 50-trading day observation period.

Under existing GAAP at the time of issuance during 2020, convertible debt instruments that may be settled in cash on conversion were required to be separated into liability and equity components in a manner that reflects the issuer’s non-convertible debt borrowing rate. The carrying amount of the liability component is based on the fair value of a similar instrument that does not contain an equity conversion option. The carrying amount allocated to the equity component, which is recognized as a debt discount, represents the difference between the proceeds from the issuance of the notes and the fair value of the liability component of the notes. Based on this debt to equity ratio, debt issuance costs are then allocated to the liability and equity components in a similar manner. Accordingly, at issuance the Company allocated $336.1 million to the debt liability and $53.6 million to additional paid-in capital. The difference between the principal amount of the Convertible Senior Notes and the liability component, inclusive of issuance costs, represents the debt discount, which the Company amortized to interest expense over the term of the Convertible Senior Notes using an effective interest rate of 3.25%. During the year ended December 31, 2020, the Company recognized interest expense of $4.4 million. As of December 31, 2020, the net carrying value of the Notes was $340.6 million.

In the first quarter of 2021, the Company early adopted ASU 2020-06, “Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Equity’s Own Equity (Subtopic 815-40)”. The Company used the modified retrospective method which resulted in a reduction in non-cash interest expense and reclassification of equity component of the convertible senior notes of $55.0 million and equity component of the debt issuance costs of $1.4 million to liabilities on the consolidated balance sheet. The Company also adjusted the carrying amount of the convertible senior notes to what it would have been if the Company had applied ASU 2020-06 from the inception of the Notes and recorded the offset of the carrying amount adjustment of $3.7 million in retained earnings on January 1, 2021.

The Company recognized interest expense of $0.7 million and $0.7 million for the three months ended March 31, 2022 and March 31, 2021, respectively.  As of March 31, 2022 and December 31, 2021, the carrying value of the Notes was $400.0 million.

Convertible Note Hedge and Warrant Transactions

In connection with the sale of the Convertible Senior Notes, the Company purchased a bond hedge designed to mitigate the potential dilution from the conversion of the Convertible Senior Notes. Under the five-year term of the bond hedge, upon a conversion of the bonds, the Company will receive the number of shares of common stock equal to the remaining common stock deliverable upon conversion of the Convertible Senior Notes if the conversion value exceeds the principal amount of the Notes. The aggregate number of shares that the Company could be obligated to issue upon conversion of the Convertible Senior Notes is approximately 8.9 million shares. The cost of the convertible note hedge transactions was $55.0 million.

The cost of the convertible note hedge was partially offset by the Company’s sale of warrants to acquire approximately 8.9 million shares of the Company’s common stock. The warrants were initially exercisable at a price of at least $66.46 per share and are subject to customary adjustments upon the occurrence of certain events, such as the payment of dividends. The Company received $13.8 million in cash proceeds from the sales of these warrants.  

The bond hedge and warrant transactions effectively increased the conversion price associated with the Convertible Senior Notes during the term of these transactions from 35%, or $44.86, to 100%, or $66.46, at their issuance, thereby reducing the dilutive economic effect to shareholders upon actual conversion.

The bond hedges and warrants are indexed to, and potentially settled in, shares of the Company’s common stock. The net cost of $41.2 million for the purchase of the bond hedges and sale of the warrants was recorded as a reduction to additional paid-in capital in the consolidated balance sheets.

At issuance, the Company recorded a deferred tax liability of $16.2 million related to the Convertible Senior Notes debt discount and the capitalized debt issuance costs. The Company also recorded a deferred tax asset of $16.5 million related to the convertible note hedge transactions and the tax basis of the capitalized debt issuance costs through additional paid-in capital. The deferred tax liability and deferred tax asset were included net in “Deferred tax assets” on the consolidated balance sheets. Upon adoption of ASU 2020-06, the Company reversed the deferred tax liability of $13.9 million that the Company had recorded at issuance related to the Convertible Senior Note debt discount and recorded an additional deferred tax liability of $0.4 million related to the capitalized debt issuance costs. In addition, the Company recorded a $0.9 million adjustment to the deferred tax asset through retained earnings related to the tax effect of book accretion recorded in 2020 and reversed upon adoption.
