Borrowings [Abstract] |
Borrowings | Note 11 Borrowings Credit Facility On October 10, 2014, the Company and certain of its subsidiaries entered into a $150,000 five-year revolving, unsecured credit facility (the “Credit Agreement”) with PNC Bank, National Association, as Administrative Agent, PNC Capital Markets LLC, as Sole Lead Arranger and Sole Bookrunner, HSBC Bank USA, N.A., as Syndication Agent, and the other lenders party thereto (collectively, the “Lenders”). The Credit Agreement comprises a revolving loan facility that provides for advances in the initial aggregate principal amount of up to $150,000 (the “Credit Facility”). Subject to certain terms and conditions contained in the Credit Agreement, the Company may, at its option and subject to customary conditions, request an increase in the aggregate principal amount available under the Credit Facility by an additional $75,000. The Credit Agreement includes provisions for the issuance of letters of credit and swingline loans. The Credit Agreement is guaranteed by certain of the Company’s material domestic subsidiaries (the “Guarantors”). Pursuant to the Credit Agreement, the Guarantors guarantee to the Lenders, among other things, all of the obligations of the Company and each other Guarantor under the Credit Agreement. From time to time, the Company may be required to cause additional material domestic subsidiaries to become Guarantors under the Credit Agreement. Generally, amounts outstanding under the Credit Facility bear interest, at the Company’s option, at either the Base Rate or the LIBOR Rate, in each case, plus an applicable margin. Base Rate advances bear interest at a rate per annum equal to the sum of (i) the highest of (A) the Administrative Agent’s prime rate, (B) the Federal Funds Open Rate plus 0.5% or (C) the Daily LIBOR Rate for a one month interest period plus 1%, and (ii) an applicable margin that ranges from 0.25% to 0.50% based upon the Company’s consolidated total leverage ratio. LIBOR Rate advances bear interest at a rate based upon the London interbank offered rate for the applicable interest period, plus an applicable margin that ranges from 1.25% to 1.50% based upon the Company’s consolidated total leverage ratio. Under the terms of the Credit Agreement, (i) accrued interest on each loan bearing interest at the Base Rate is payable quarterly in arrears and (ii) accrued interest on each loan bearing interest at the LIBOR Rate is payable in arrears on the earlier of (A) quarterly and (B) the last day of each applicable interest payment date for each loan. The Credit Facility is scheduled to mature on October 10, 2019, at which time all amounts outstanding thereunder will be due and payable. The Company is required to pay certain fees in connection with the Credit Facility, including a quarterly commitment fee equal to the product of the amount of the average daily available revolving commitments under the Credit Agreement multiplied by a percentage that ranges from 0.20% to 0.25% depending upon the Company’s leverage ratio, as well as customary administrative fees. The Credit Agreement contains customary representations, warranties, covenants and default provisions for a Credit Facility of this type, including, but not limited to, financial covenants, limitations on liens and the incurrence of debt, covenants to preserve corporate existence and comply with laws and covenants regarding the use of proceeds of the Credit Facility. The financial covenants include a maximum consolidated total leverage ratio, which is the ratio of consolidated total funded indebtedness to consolidated EBITDA (earnings before interest, taxes, depreciation and amortization expense), as defined in the Credit Agreement, of 3.00 to 1.00, and a minimum interest coverage ratio, which is the ratio of Consolidated EBITDA to cash interest expense, of 3.50 to 1.0. The Company is only required to be in compliance with the financial covenants as of the end of any fiscal quarter in which there are any loans outstanding at any time during such fiscal quarter. There was no outstanding balance on the Credit Facility as of December 31, 2014. 5.5% Senior Convertible Notes and Interest Expense In November 2011, the Company completed the private placement of $152,000 of 5.50% senior convertible notes due in December 2016. These notes are senior unsecured obligations and rank equal in right of payment with all the Company’s existing and future senior unsecured indebtedness. They are also senior in right of payment to any subordinated indebtedness that the Company may incur in the future. The notes accrue interest at the rate of 5.50% per year payable in cash semi-annually on June 15 and December 15 of each year. During 2014, the remaining $12,540 of outstanding notes were converted, reflecting a loss of $1,806 for the year ended December 31, 2014, compared to losses of $11,275 and $7,021, respectively, for the years ended December 31, 2013 and 2012. As of December 31, 2014, there is no outstanding balance for the notes. The following table summarizes the principal amounts and related unamortized discount on convertible notes:
(in thousands) |  | 2014 |  | 2013
Principal amount of convertible notes |  | $ | — |  | $ | 12,540
Unamortized discount on convertible notes |  |  | — |  |  | (1,124)
Net carrying value |  | $ | — |  | $ | 11,416
Interest Expense Interest expense totaled $1,227, $3,425 and $12,468 for the years ended December 31, 2014, 2013 and 2012, respectively and interest income totaled $482, $1,258, and $168 for the years ended December 31, 2014, 2013 and 2012, respectively, reflecting the combined effect of the issuance and conversion of the senior convertible notes and lower interest rates on investments. Other Debt In connection with its acquisition of LayerWise, the Company assumed a portion of LayerWise’s outstanding bank debt, consisting of $1,427 of revolving credit facilities and $240 in term loans. The term loans bear interest at rates ranging from 1.34% to 5.40% as of December 31, 2014. The outstanding balance on the term loans was $127, as of December 31, 2014, all of which was current. There were no borrowings outstanding under the revolving credit facilities as of December 31, 2014. There is a 0.125% commitment fee on the unused portion of the facilities.
