LONG TERM DEBT

NOTE 14:- LONG TERM DEBT

In connection with financing the acquisition of inContact (refer to Note 1b) which closed on November 14, 2016, the Company entered into a Credit Agreement with certain lenders, according to which the following credit facilities were issued: 1) a long-term loan of $475,000, and 2) a revolving credit loan of up to $75,000.

The Credit Agreement contains a number of covenants and restrictions that among other things, and subject to certain agreed upon exceptions, require the Company and its subsidiaries to satisfy certain financial covenants and restricts the ability of the Company and its subsidiaries to incur liens, incur additional indebtedness, make loans and investments, engage in mergers and acquisitions, engage in asset sales, declare dividends or redeem or repurchase capital stock, prepay, redeem or purchase subordinated debt and amend or otherwise alter debt agreements, in each case, subject to certain agreed upon exceptions. A failure to comply with these covenants could permit the lenders under the Credit Agreement to declare all amounts borrowed under the Credit Agreement, together with accrued interest and fees, to be immediately due and payable. As of December 31, 2018, the Company was in compliance with all covenants and requirements outlined in the Credit Agreement.

Long term loan

On January 2017, the Company prepaid a principal amount of $260,000 which resulted in $5,300 amortization of debt issuance costs. In addition, the contractual principal payments for the long-term loan have changed and the Company will pay the entire remaining principal of $215,000 at the final maturity date which is December 31, 2021.

The long-term loan bears interest through maturity at a variable rate based upon, at the Company's option every interest period, either (a) the LIBOR rate for Eurocurrency borrowing or (b) an Alternate Base Rate ("ABR"), which is the highest of (i) the administrative agent's prime rate, (ii) one-half of 1.00% in excess of the overnight U.S. Federal Funds rate, and (iii) 1.00% in excess of the one-month LIBOR), plus in each case, an applicable margin. The applicable margin for Eurocurrency loans ranges, based on the applicable total net leverage ratio, from 1.25% to 2.00% per annum and the applicable margin for ABR loans ranges, based on the applicable total net leverage ratio, from 0.25% to 1.00% per annum.

Debt issuance costs of $10,158 attributable to the long-term loan are amortized as interest expense over the contractual term of the loan using the effective interest rate.

The carrying values of the liability's components are reflected in the Company's accompanying consolidated balance sheets as follows:

	December 31,
	2018			2017
Principal	$	215,000		$	215,000

Pursuant to the Credit Agreement, the Company has also been granted a revolving credit facility that entitles the Company to borrow up to $75,000 through December 2021 with interest payable on the borrowed amount set at the same terms as the term loan, as well as a quarterly commitment fee on unfunded amounts ranging from 0.25% to 0.5%, subject to the achievement of certain leverage levels. As of December 31, 2018, no amounts had been funded.

Debt issuance costs of $1,667 attributable to the revolving credit loan are capitalized and amortized as interest expense over the contractual term of the agreement on a straight line basis.

Exchangeable Senior Notes

In January 2017, the Company issued $287,500 aggregate principal amount of Exchangeable Senior Notes (the "Notes") due 2024. The following table summarizes some key facts and terms regarding the outstanding Notes:

The Company may provide additional ADSs upon conversion if there is a "Make-Whole Fundamental Change" in the business as defined in the indenture governing the Notes.

The Notes are not redeemable by the Company prior to the maturity date apart from certain cases as defined in the indenture governing the Notes.

Exchangeable notes hedge transactions

In connection with the pricing of the Notes, the Company has entered into privately negotiated exchangeable note hedge transactions with some of the initial purchasers and/or their respective affiliates (the "Option Counterparties").

Subject to customary anti-dilution adjustments substantially similar to those applicable to the Notes, the exchangeable note hedge transactions cover partial number of ADSs that will initially underline the Notes.

The note hedge transactions are expected generally to reduce potential dilution to the ADSs and/or cash payments the Company is required to make in excess of the principal amount, in each case, upon any exchange of the Notes.

A portion of the call-options can be settled upon a surrender of the same amounts of Notes by a holder. Settlement can be done in cash, ADSs or a combination of both, at the Company's election.

Concurrently with the Company's entry into the exchangeable note hedge transactions, the Company has entered into warrant transactions with the Option Counterparties relating to the same number of ADSs (3,457,475), with a strike price of $101.82 per ADS, subject to customary anti‑dilution adjustments.

The warrants are exercisable for a period of three months as of the notes maturity date.

GAAP requires measuring such transactions as equity components. The Company has recorded a net decrease of $20,281 in additional paid in capital in 2017.
