|Debt Disclosure [Abstract]|
On September 30, 2014, we entered into an agreement for a secured revolving credit facility (as amended by the amendments discussed below, the “Credit Facility”) to refinance our outstanding revolving loans. The Credit Facility provides for an aggregate principal amount of up to $200.0 million of revolving loans, with sublimits of $10.0 million for the issuance of letters of credit and $20.0 million for swingline loans (“Revolving Facility”). Additionally, the Credit Facility allows us, subject to certain conditions, to request additional term loans or revolving commitments up to an aggregate principal amount of $150.0 million, plus an amount that would not cause our Senior Leverage Ratio, as defined below, to exceed 3.25 to 1.00 (“Accordion Feature”). Under the First Amendment, discussed below, we used availability provided by the Accordion Feature to add a term loan in an original principal amount of $125.0 million (“Term Loan”) to the Credit Facility. In February 2017, we used borrowing capacity under the Accordion Feature to add a delayed draw term loan with an original principal amount of up to $200.0 million (“Delayed Draw Term Loan”). At our option, amounts outstanding under the Credit Facility accrued interest, prior to the amendments described below, at a per annum rate equal to either LIBOR, plus a margin ranging from 1.25% to 1.75%, or the Base Rate, plus a margin ranging from 0.25% to 0.75% (“Applicable Margin”). The base LIBOR is, at our discretion, equal to either one, two, three, or six month LIBOR. The Base Rate is defined as the greater of Wells Fargo’s prime rate, the Federal Funds Rate plus 0.50%, or one month LIBOR plus 1.00%. In each case, the Applicable Margin is determined based upon our Net Leverage Ratio, as defined below. As amended, the Credit Facility matures on February 27, 2022.
Certain of our existing and future material domestic subsidiaries are required to guarantee our obligations under the Credit Facility, and the obligations under the Credit Facility are secured by substantially all of our assets and the assets of the subsidiary guarantors. The Credit Facility contains customary covenants, subject in each case to customary exceptions and qualifications. Our covenants include, among other limitations, a requirement that we comply with a maximum Consolidated Net Leverage Ratio, a minimum Consolidated Interest Coverage Ratio, and a maximum Consolidated Senior Secured Net Leverage Ratio.
Consolidated Net Leverage Ratio: The Consolidated Net Leverage Ratio (“Net Leverage Ratio”) is the ratio of consolidated funded indebtedness, as defined in the Credit Facility, on the last day of each fiscal quarter to the sum of the four previous consecutive fiscal quarters’ consolidated EBITDA, as defined in the Credit Facility. The Net Leverage Ratio generally may not exceed 4.00 to 1.00, but automatically increases to 5.00 to 1.00 following an acquisition having aggregate consideration equal to or greater than $150.0 million and occurring within a specified time period following an unsecured debt issuance equal to or greater than $225.0 million. The automatic increase may occur once during the term of the Credit Facility and lasts for two consecutive fiscal quarters, after which it is incrementally reduced until the ratio returns to 4.00 to 1.00. The automatic increase was triggered by our acquisition of On-Site in September 2017. As a result, the maximum Net Leverage Ratio was 5.00 to 1.00 at December 31, 2017, after which it will be incrementally reduced until it returns to 4.00 to 1.00 on September 30, 2019.
Consolidated Interest Coverage Ratio: The Consolidated Interest Coverage Ratio (“Interest Coverage Ratio”) is the ratio of the sum of our four previous fiscal quarters’ consolidated EBITDA to our aggregate interest expense for the same period. The Interest Coverage Ratio must not be less than 3.00 to 1.00 on the last day of each fiscal quarter. The Interest Coverage Ratio was modified by the Fourth Amendment to exclude non-cash interest attributable to the Convertible Notes, as defined below.
Consolidated Senior Secured Net Leverage Ratio: The Consolidated Senior Secured Net Leverage Ratio (“Senior Leverage Ratio”) is the ratio of consolidated senior secured indebtedness, as defined in the Credit Facility, on the last day of each fiscal quarter to the sum of the four previous consecutive fiscal quarters’ consolidated EBITDA and may not exceed 3.50 to 1.00. At our option, this ratio may be increased to 3.75 to 1.00 for a period of one year following the completion of an acquisition having aggregate consideration greater than $50.0 million. We are not permitted to exercise this option more than one time during any consecutive eight quarter period. As of December 31, 2017, we had not exercised our option to increase the Senior Leverage Ratio.
As of December 31, 2017, we were in compliance with the covenants under our Credit Facility.
Since it was first entered into, the Credit Facility has been amended as follows:
First Amendment: In February 2016, we entered into an amendment to the Credit Facility (“First Amendment”). The First Amendment provided for the Term Loan, which is coterminous with the existing Credit Facility. The Term Loan reduced the amount available for additional term loans and revolving commitments available under the Accordion Feature. Under the terms of the First Amendment, an additional pricing tier was added to the Applicable Margin which modified the range to 1.25% to 2.00% for LIBOR loans, and 0.25% to 1.00% for Base Rate loans. The Term Loan’s amortization schedule was subsequently amended by the Third Amendment, defined below. Under the amended amortization schedule, we began making quarterly principal payments with respect to the Term Loan of $0.8 million on June 30, 2017. The quarterly principal payments will increase to $1.5 million on June 30, 2018, and to $3.1 million on June 30, 2020. Any remaining principal balance on the Term Loan is due on the maturity date. We incurred debt issuance costs in the amount of $0.7 million in conjunction with the execution of the First Amendment.
Second and Third Amendments: In February 2017, we entered into the second (“Second Amendment”) and third amendments (“Third Amendment”) to the Credit Facility. Among other changes, the Second Amendment replenished the amount available under the Accordion Feature, previously reduced through the issuance of the Term Loan, to $150.0 million, plus an amount that would not cause our Senior Leverage Ratio to exceed 3.25 to 1.00. The Third Amendment provided for a delayed draw term loan, which was initially available to be drawn until May 31, 2017 (“Delayed Draw Term Loan”). The Delayed Draw Term Loan reduced the amount available for additional term loans and revolving commitments available under the Accordion Feature. We incurred debt issuance costs in the amount of $1.3 million in conjunction with the execution of the Second and Third amendments.
Fourth Amendment: On April 3, 2017, we entered into the fourth amendment to the Credit Facility (“Fourth Amendment”). The Fourth Amendment modified certain terms of the Credit Facility to, among other things, increase the maximum Net Leverage Ratio, provide for the maximum Senior Leverage Ratio, and provide for an additional pricing tier for interest rates and fees if the Company’s Net Leverage Ratio equals or exceeds 4.00 to 1.00, resulting in a new Applicable Margin range of 1.25% to 2.25% for LIBOR loans and 0.25% to 1.25% for Base Rate loans.
Fifth and Sixth Amendments: The availability period of the Delayed Draw Term Loan was extended through August 31, 2017, under the fifth amendment to the Credit Facility, which was executed in May 2017. In August 2017, the availability period of the Delayed Draw Term Loan was further extended through December 31, 2017, under the sixth amendment to the Credit Facility.
The Delayed Draw Term Loan was drawn for the $200.0 million of funds available on December 5, 2017. These funds were used to finance our acquisition of LRO, which was completed in December 2017. Subsequent to disbursal of the Delayed Draw Term Loan funds, we began making quarterly principal payments of $1.3 million on December 31, 2017. The quarterly principal payments increase to $2.5 million beginning on June 30, 2018, and to $5.0 million beginning on June 30, 2020. Any remaining principal balance on the Delayed Draw Term Loan is due on the maturity date.
Revolving loans under the Credit Facility may be voluntarily prepaid and re-borrowed. Principal payments on the Term Loan and Delayed Draw Term Loan (collectively, the “Term Loans”) are due in quarterly installments, as described above, and may not be re-borrowed. Accumulated interest on amounts outstanding under the Credit Facility is due and payable quarterly, in arrears, for loans bearing interest at the Base Rate and at the end of the applicable interest period in the case of loans bearing interest at the adjusted LIBOR. All outstanding principal and accrued but unpaid interest is due on the maturity date. The Term Loans are subject to mandatory repayment requirements in the event of certain asset sales or if certain insurance or condemnation events occur, subject to customary reinvestment provisions. The Company may prepay the Term Loans in whole or in part at any time, without premium or penalty, with prepayment amounts to be applied to remaining scheduled principal amortization payments as specified by the Company.
As of December 31, 2017, we had $150.0 million of available credit under our Revolving Facility plus additional amounts under the Accordion Feature of the Credit Facility. We incur commitment fees on the unused portion of the Revolving Facility. The weighted-average interest rates of short-term borrowings during the years ended December 31, 2017 and 2016, were 3.14% and 1.75%, respectively.
Principal outstanding, and unamortized debt issuance costs for the Term Loans, were as follows at December 31, 2017 and 2016:
Unamortized debt issuance costs for the Revolving Facility were $0.6 million and $0.8 million at December 31, 2017 and 2016, respectively, and are included in the line “Other assets” in the Consolidated Balance Sheets.
Future maturities of principal under the Term Loans are as follows for the years ending December 31, in thousands:
In May 2017, the Company issued convertible senior notes with aggregate principal of $345.0 million (including the underwriters’ exercise in full of their over-allotment option of $45.0 million) which mature on November 15, 2022 (“Convertible Notes”). The Convertible Notes were issued under an indenture dated May 23, 2017 (“Indenture”), by and between the Company and Wells Fargo Bank, N.A., as Trustee. We received net proceeds from the offering of approximately $304.2 million after adjusting for debt issuance costs, including the underwriting discount, the net cash used to purchase the Note Hedges and the proceeds from the issuance of the Warrants which are discussed below.
The Convertible Notes accrue interest at a rate of 1.50%, payable semi-annually on May 15 and November 15 of each year beginning on November 15, 2017. On or after May 15, 2022, and until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert their Convertible Notes at their option. The Convertible Notes are convertible at an initial rate of 23.84 shares per $1,000 of principal (equivalent to an initial conversion price of approximately $41.95 per share of our common stock). The conversion rate is subject to customary adjustments for certain events as described in the Indenture. Upon conversion, we will pay or deliver, as the case may be, cash, shares of our common stock or a combination of cash and shares of our common stock, at our election. It is the Company’s current intent to settle conversions of the Convertible Notes through combination settlement, which involves repayment of the principal portion in cash and any excess of the conversion value over the principal amount in shares of our common stock.
Holders may convert their Convertible Notes, at their option, prior to May 15, 2022 only under the following circumstances:
We may not redeem the Convertible Notes prior to their maturity date, and no sinking fund is provided for them. If we undergo a fundamental change, as described in the Indenture, subject to certain conditions, holders may require us to repurchase for cash all or any portion of their Convertible Notes. The fundamental change repurchase price is equal to 100% of the principal amount of the Convertible Notes to be repurchased, plus accrued and unpaid interest up to, but excluding, the fundamental change repurchase date. If holders elect to convert their Convertible Notes in connection with a make-whole fundamental change, as described in the Indenture, the Company will, to the extent provided in the Indenture, increase the conversion rate applicable to the Convertible Notes.
The Convertible Notes are senior unsecured obligations and rank senior in right of payment to any of our indebtedness that is expressly subordinated in right of payment to the Convertible Notes and equal in right of payment to any of our existing and future unsecured indebtedness that is not subordinated. The Convertible Notes are effectively junior in right of payment to any of our secured indebtedness (to the extent of the value of assets securing such indebtedness) and structurally junior to all existing and future indebtedness and other liabilities, including trade payables, of our subsidiaries. The Indenture does not limit the amount of debt that we or our subsidiaries may incur. The Convertible Notes are not guaranteed by any of our subsidiaries.
The Indenture does not contain any financial or operating covenants or restrictions on the payment of dividends, the incurrence of indebtedness, or the issuance or repurchase of securities by us or any of our subsidiaries. The Indenture contains customary events of default with respect to the Convertible Notes and provides that upon certain events of default occurring and continuing, the Trustee may, and the Trustee at the request of holders of at least 25% in principal amount of the Convertible Notes shall, declare all principal and accrued and unpaid interest, if any, of the Convertible Notes to be due and payable. In case of certain events of bankruptcy, insolvency or reorganization, involving us or a significant subsidiary, all of the principal of and accrued and unpaid interest on the Convertible Notes will automatically become due and payable.
In accounting for the issuance of the Convertible Notes, the Company separated the Convertible Notes into liability and equity components. We allocated $282.5 million of the Convertible Notes to the liability component, and $62.5 million to the equity component. The excess of the principal amount of the liability component over its carrying amount is amortized to interest expense over the term of the Convertible Notes using the effective interest method. The equity component will not be remeasured as long as it continues to meet the conditions for equity classification.
We incurred issuance costs of $9.8 million related to the Convertible Notes. Issuance costs were allocated to the liability and equity components based on their relative values. Issuance costs attributable to the liability component are being amortized to interest expense over the term of the Convertible Notes, and issuance costs attributable to the equity component are included along with the equity component in stockholders' equity.
The net carrying amount of the Convertible Notes at December 31, 2017, was as follows, in thousands:
The following table sets forth total interest expense related to the Convertible Notes for the year ended December 31, 2017, in thousands:
Convertible Note Hedges and Warrants
On May 23, 2017, we entered into privately negotiated transactions to purchase hedge instruments (“Note Hedges”), covering approximately 8.2 million shares of our common stock at a cost of $62.5 million. The Note Hedges are subject to anti-dilution provisions substantially similar to those of the Convertible Notes, have a strike price of approximately $41.95 per share, are exercisable by us upon any conversion under the Convertible Notes, and expire on November 15, 2022.
The Note Hedges are generally expected to reduce the potential dilution to our common stock (or, in the event the conversion is settled in cash, to reduce our cash payment obligation) in the event that at the time of conversion our stock price exceeds the conversion price under the Convertible Notes. The cost of the Note Hedges is expected to be tax deductible as an original issue discount over the life of the Convertible Notes, as the Convertible Notes and the Note Hedges represent an integrated debt instrument for tax purposes. The cost of the Note Hedges was recorded as a reduction of our additional paid-in capital in the accompanying Consolidated Financial Statements.
On May 23, 2017, the Company also sold warrants for the purchase of up to 8.2 million shares of our common stock for aggregate proceeds of $31.5 million (“Warrants”). The Warrants have a strike price of $57.58 per share and are subject to customary anti-dilution provisions. The Warrants will expire in ratable portions on a series of expiration dates commencing on February 15, 2023. The proceeds from the issuance of the Warrants were recorded as an increase to our additional paid-in capital in the accompanying Consolidated Financial Statements.
The Note Hedges are transactions that are separate from the terms of the Convertible Notes and the Warrants, and holders of the Convertible Notes and the Warrants have no rights with respect to the Note Hedges. The Warrants are similarly separate in both terms and rights from the Note Hedges and the Convertible Notes. As of December 31, 2017, no Note Hedges or Warrants had been exercised.
The entire disclosure for long-term debt.
