In December 2016, we issued $100.0 million of unsecured convertible senior notes (“Convertible Notes”) that mature on December 1, 2021, of which $48.6 million principal amount was outstanding at March 31, 2021. The notes bear interest at a rate of 4.0% per year, payable semiannually in arrears on June 1 and December 1 of each year. Holders may convert the notes at their option at any time prior to the close of business on the business day immediately preceding June 1, 2021, only under the following circumstances: • during any calendar quarter (and only during such calendar quarter) if the last reported sale price of our common stock for at least 20 trading days (regardless of whether consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price of the notes in effect on each applicable trading day; • during the five five • upon the occurrence of specified corporate events, as described in the indenture governing the notes, such as a consolidation, merger, or share exchange. On or after June 1, 2021 until the close of business on the business day immediately preceding the maturity date, holders may convert their notes at any time, regardless of whether any of the foregoing conditions have been satisfied. As of May 3, 2021, the notes were not convertible. The notes are convertible into, at our election, cash, shares of common stock, or a combination of both, subject to satisfaction of specified conditions and during specified periods, as described above. If converted, we currently intend to pay cash for the principal amount of the notes converted. The conversion rate is 107.1381 shares of our common stock per $1,000 principal amount of notes (equivalent to an initial conversion price of $9.33 per share of common stock), subject to adjustment in certain circumstances. We may not redeem the notes prior to their maturity date. In accordance with accounting guidance for convertible debt with a cash conversion option, we separately accounted for the debt and equity components of the notes in a manner that reflected our estimated nonconvertible debt borrowing rate. As of March 31, 2021, the carrying amount of the debt component was $46.3 million, which is net of the unamortized debt discount and debt issuance costs of $2.3 million. Including the impact of the unamortized debt discount and debt issuance costs, the effective interest rate on the notes is approximately 11.3%. During the first quarter of 2021, we repurchased $18.3 million of our Convertible Notes in the open market for a total cost of $18.1 million, and recognized a net loss of $0.8 million reflecting the difference in the amount paid and the net carrying value of the extinguished debt, including original issue discount and debt issuance costs. Asset-Based Loan Facility. In May 2016, we entered into an asset-based revolving credit agreement, which was amended in October 2017 and in March 2019 (as amended, the “ABL Facility”). The ABL Facility provides financing of up to $200.0 million available for borrowings (inclusive of letters of credit) and can be increased up to a maximum capacity of $275.0 million, subject to certain conditions. As of March 31, 2021, our total availability under the ABL Facility was $88.3 million, of which $11.0 million was drawn, resulting in remaining availability of $77.2 million. The ABL Facility terminates in March 2024; however, the ABL Facility has a springing maturity date that will accelerate the maturity of the ABL Facility to September 1, 2021 if, prior to such date, the Convertible Notes have not been repurchased, redeemed, refinanced, exchanged or otherwise satisfied in full or we have not escrowed an amount of funds, that together with the amount that we establish as a reserve against our borrowing capacity, is sufficient for the future settlement of the Convertible Notes at their maturity. The ABL Facility requires a minimum consolidated fixed charge coverage ratio of 1.25 to 1.0 calculated based on the trailing twelve-month period ended June 30, 2021 and remaining unused availability of at least $25.0 million to utilize borrowings or assignment of availability under the ABL Facility towards funding the repayment of the Convertible Notes. Borrowing availability under the ABL Facility is calculated based on eligible U.S. accounts receivable, inventory, and, subject to satisfaction of certain financial covenants as described below, composite mats included in the rental fleet, net of reserves and limits on such assets included in the borrowing base calculation. To the extent pledged by us, the borrowing base calculation also includes the amount of eligible pledged cash. The lender may establish such reserves, in part based on appraisals of the asset base, and other limits at its discretion which could reduce the amounts otherwise available under the ABL Facility. Availability associated with eligible rental mats will also be subject to maintaining a minimum consolidated fixed charge coverage ratio of 1.5 to 1.0 and at least $1.0 million of operating income for the Site and Access Solutions business, each calculated based on a trailing twelve-month period. As of May 3, 2021, our total availability under the ABL Facility was $82.6 million, of which $16.0 million was drawn, resulting in remaining availability of $66.5 million. This availability under the ABL Facility excludes $24.2 million related to eligible rental mats as we failed to satisfy the required minimum consolidated fixed charge coverage ratio, as measured on the trailing twelve-month period ended March 31, 2021. We expect to satisfy the minimum consolidated fixed charge coverage ratio as required to include eligible rental mats in the borrowing availability under the ABL Facility following the second quarter of 2021 and expect to satisfy the June 30, 2021 ABL Facility requirements to be able to utilize borrowings or assignment of availability under the ABL Facility towards funding the repayment of the Convertible Notes prior to September 1, 2021. Under the terms of the ABL Facility, we may elect to borrow at a variable interest rate based on either, (1) LIBOR subject to a floor of zero or (2) a base rate equal to the highest of: (a) the federal funds rate plus 50 basis points, (b) the prime rate of Bank of America, N.A. and (c) LIBOR, subject to a floor of zero, plus 100 basis points, plus, in each case, an applicable margin per annum. The applicable margin ranges from 150 to 200 basis points for LIBOR borrowings, and 50 to 100 basis points for base rate borrowings, based on the consolidated fixed charge coverage ratio as defined in the ABL Facility. As of March 31, 2021, the applicable margin for borrowings under our ABL Facility was 200 basis points with respect to LIBOR borrowings and 100 basis points with respect to base rate borrowings. The weighted average interest rate for the ABL Facility was 2.1% at March 31, 2021. In addition, we are required to pay a commitment fee on the unused portion of the ABL Facility ranging from 25 to 37.5 basis points, based on the level of outstanding borrowings, as defined in the ABL Facility. As of March 31, 2021, the applicable commitment fee was 37.5 basis points. The ABL Facility is a senior secured obligation, secured by first liens on substantially all of our U.S. tangible and intangible assets, and a portion of the capital stock of our non-U.S. subsidiaries has also been pledged as collateral. The ABL Facility contains customary operating covenants and certain restrictions including, among other things, the incurrence of additional debt, liens, dividends, asset sales, investments, mergers, acquisitions, affiliate transactions, stock repurchases and other restricted payments. The ABL Facility also requires a minimum consolidated fixed charge coverage ratio of 1.0 to 1.0 calculated based on a trailing twelve-month period if availability under the ABL Facility falls below $22.5 million. In addition, the ABL Facility contains customary events of default, including, without limitation, a failure to make payments under the facility, acceleration of more than $25.0 million of other indebtedness, certain bankruptcy events, and certain change of control events. Other Debt. In February 2021, a U.K. subsidiary entered a £6.0 million (approximately $8.3 million) term loan facility that matures in February 2024, the proceeds of which were used to pay down the ABL Facility. The term loan bears interest at a rate of LIBOR plus a margin of 3.4% per year, payable in quarterly installments of £375,000 plus interest beginning March 2021 and a £1.5 million payment due at maturity. We had $7.8 million outstanding under this arrangement at March 31, 2021. Certain of our other foreign subsidiaries maintain local credit arrangements consisting primarily of lines of credit or overdraft facilities which are generally renewed on an annual basis. We utilize local financing arrangements in our foreign operations in order to provide short-term local liquidity needs. We had $6.5 million and $3.5 million outstanding under these arrangements at March 31, 2021 and December 31, 2020, respectively. In addition, at March 31, 2021, we had $50.2 million in outstanding letters of credit, performance bonds, and other guarantees for which certain of the letters of credit are collateralized by $5.8 million in restricted cash. Our financial instruments include cash and cash equivalents, receivables, payables, and debt. We believe the carrying values of these instruments, with the exception of our Convertible Notes, approximated their fair values at March 31, 2021 and |
