2018 Credit Agreement

On May 31, 2018, the Company entered into a credit agreement (the "2018 Credit Agreement") that provides for (1) a $1,770.0 million term loan B facility (the "US Term Loan Facility"), (2) a €750.0 million term loan B facility (the "EMEA Term Loan Facility"), and (3) a $200.0 million revolving credit facility (the "Revolving Line of Credit Facility") (which includes a $50.0 million letter of credit facility). The US Term Loan Facility was issued at an original issuance discount of $8.9 million and the EMEA Term Loan Facility was issued at an original issuance discount of €3.8 million. The Company is the borrower under the U.S. Term Loan Facility and the Revolving Line of Credit Facility. The Company's wholly-owned subsidiary GTT Communications B.V. is the borrower under the EMEA Term Loan Facility (the "EMEA Borrower").

The maturity date of the US Term Loan Facility and the EMEA Term Loan Facility (collectively the "Term Loan Facilities") is May 31, 2025 and the maturity date of the Revolving Line of Credit Facility is May 31, 2023. Each maturity date may be extended per the terms of the 2018 Credit Agreement.

The principal amounts of the US Term Loan Facility and EMEA Term Loan Facility are payable in equal quarterly installments of $4.425 million and €1.875 million, respectively, commencing on September 30, 2018 and continuing thereafter until the maturity date when the remaining balances of outstanding principal amount is payable in full.

The Company may prepay loans under the 2018 Credit Agreement at any time, subject to certain notice requirements, LIBOR breakage costs, and prepayment fees noted above.

At the Company’s election, the US Term Loan Facility may be made as either Base Rate Loans or Eurocurrency Loans. The EMEA Term Loan Facility will bear interest at the European Money Markets Institute EURIBO Rate plus the applicable margin. The applicable margin for the US Term Loan Facility is 1.75% for Base Rate Loans and 2.75% for Eurocurrency Loans, subject to a “LIBOR floor” of 0.00%. The applicable margin for the EMEA Term Loan Facility is 3.25%, subject to a “EURIBOR floor” of 0.00%. The applicable margin for revolving loans under the Revolving Line of Credit Facility is 1.75% for Base Rate Loans, 2.75% for Eurocurrency Loans denominated in U.S. Dollars and certain other approved currencies other than Euros, and 3.25% for revolving loans denominated in Euros.

The proceeds from the US Term Loan Facility and EMEA Term Loan Facility were used to finance the Interoute acquisition, to repay amounts outstanding under the Company's prior term loan facility, and to pay costs associated with such transactions.

On June 5, 2019, the Company entered into an Incremental Revolving Credit Assumption Agreement ("Incremental Agreement") to the 2018 Credit Agreement. The Incremental Agreement establishes $50.0 million in new revolving credit commitments, bringing the total sum of revolving credit commitments under the 2018 Credit Agreement, as modified by the Incremental Agreement, to $250.0 million. The revolving credit commitments made pursuant to the Incremental Agreement have terms and conditions identical to the existing revolving credit commitments under the 2018 Credit Agreement.

The unused and available amount of the Revolving Line of Credit Facility at December 31, 2019 was as follows (amounts in millions):



Committed capacity	$	250.0
Borrowings outstanding	(140.0		)
Letters of credit issued	(10.9		)
Unused and available	$	99.1

The obligations of the Company under the 2018 Credit Agreement are secured by the substantial majority of the tangible and intangible assets of the Company. The obligations of the Company under the U.S. Term Loan Facility and the Revolving Line of Credit Facility are guaranteed by certain of its domestic subsidiaries, but not by any of the Company’s foreign subsidiaries. The obligations of the EMEA Borrower under the EMEA Term Loan Facility are guaranteed by the Company and certain of its domestic and foreign subsidiaries. None of the foreign subsidiary guarantors of the EMEA Term Loan Facility provide cross-guarantees of the guarantees of the EMEA Term Loan Facility provided by the Company and its domestic subsidiaries.

The 2018 Credit Agreement does not contain a financial covenant for the US Term Loan Facility or the EMEA Term Loan Facility, but it does include a maximum Consolidated Net Secured Leverage Ratio applicable to the Revolving Line of Credit Facility in the event that utilization exceeds 30% of the revolving loan facility commitment. On August 8, 2019, the Company entered into Amendment No. 1 to the 2018 Credit Agreement ("Amendment No. 1"), which amends the Consolidated Net Secured Leverage Ratio applicable to the Revolving Line of Credit Facility for each fiscal quarter ending September 30, 2019 through December 31, 2020. If triggered, the covenant, as amended, requires the Company to maintain a Consolidated Net Secured Leverage Ratio, on a Pro Forma Basis, below the maximum ratio specified as follows:



Fiscal Quarter Ending		Maximum Ratio
December 31, 2019		6.50:1
March 31, 2020		6.50:1
June 30, 2020		6.50:1
September 30, 2020		6.25:1
December 31, 2020		6.25:1
March 31, 2021		5.50:1
June 30, 2021		5.00:1
September 30, 2021		5.00:1
December 31, 2021		4.50:1
March 31, 2022		4.50:1
June 30, 2022 and thereafter		4.25:1

As of December 31, 2019, the Company's Consolidated Net Secured Leverage Ratio, as defined in the 2018 Credit Agreement, was approximately 6.0:1, which is below the maximum permitted ratio of 6.50:1.

In addition, Amendment No. 1 to the 2018 Credit Agreement added certain restrictions, which remain in place from the effective date of the Amendment No. 1 until the delivery of the compliance certificate for the quarter ending March 31, 2021, demonstrating compliance with the Consolidated Net Secured Leverage Ratio for that quarter, including without limitation the following: the Company and its restricted subsidiaries (as defined in the 2018 Credit Agreement) may not make certain dividends, distributions and other restricted payments (as defined in the 2018 Credit Agreement), including that the Company may not pay dividends; the Company and its restricted subsidiaries may not designate any subsidiary an “Unrestricted Subsidiary” (which would effectively remove such subsidiary from the restrictions of the 2018 Credit Agreement); the Company and its restricted subsidiaries may not make “permitted acquisitions” (as defined in the 2018 Credit Agreement) or certain other investments, unless the Company and its restricted subsidiaries have liquidity (i.e., unrestricted cash and cash equivalents and availability under the revolving credit facility under the 2018 Credit Agreement) of at least $250 million (other than the acquisition of KPN Eurorings B.V., a private limited liability company (besloten vennootschap met beperkte aansprakelijkheid) incorporated under the laws of the Netherlands with respect to which this liquidity requirement is not applicable); and the amount of incremental borrowings under the 2018 Credit Agreement that the Company and its subsidiaries may request when the Consolidated Net Secured Leverage Ratio is above 4.40 to 1.00 was reduced to $300 million minus amounts previously requested (which amount is $50 million requested under the Incremental Agreement described above).

On February 28, 2020, the Company entered into an amendment to the 2018 Credit Agreement (“Amendment No. 2”), which established incremental term loan commitments for $140 million of EMEA term loans (the “2020 EMEA Term Loan Facility”), bringing the total amounts of EMEA term loans outstanding under the 2018 Credit Agreement, as modified by Amendment No. 2, to €750 million in Euro-denominated loans and $140 million in US Dollar-denominated loans. The EMEA term loans under the 2020 EMEA Term Loan Facility were incurred with an original issue discount of $5.6 million.

The 2020 EMEA Term Loan Facility has terms substantially identical to the existing EMEA Term Loan Facility, except that: (1) each quarterly amortization payment on the 2020 EMEA Term Loan Facility will be $350,000; (2) the EMEA Term Loan Facility has call protection of 2.0% for certain mandatory and voluntary prepayments occurring on or prior to the one year anniversary of the effective date of the EMEA Term Loan Facility and 1.0% for certain mandatory and voluntary prepayments occurring following the one year anniversary of the effective date of the EMEA Term Loan Facility and until the second year anniversary thereof; (3) Amendment No. 2 added, for the benefit of the lenders under the 2020 EMEA Term Loan Facility, the same covenant restrictions contained in Amendment No. 1, except that (a) the amount of secured debt that can be incurred on a pari passu basis with the 2020 EMEA Term Loan Facility and certain types of debt incurred by non-credit parties is limited to $50 million in the aggregate and (b) certain excess asset sale proceeds will be required to prepay outstanding EMEA term loans or reinvest in long-term assets useful in the business within 30 days following receipt of such proceeds, which covenant restrictions will remain in place for so long as the existing Revolving Line of Credit Facility and the 2020 EMEA Term Loan Facility remain in effect; and (4) the applicable margin for the 2020 EMEA Term Loan Facility is (a) 3.25% for Base Rate Loans and 4.25% for Eurocurrency Loans for the first two years following the effective date of the 2020 EMEA Term Loan Facility and (b) 3.75% for Base Rate Loans and 4.75% for Eurocurrency Loans on and following the second anniversary of the effective date of the 2020 EMEA Term Loan Facility.

The proceeds of the 2020 EMEA Term Loan Facility were used to repay amounts outstanding under the Revolving Line of Credit Facility and for general corporate purposes.

Interest Rate Swaps

In April and May 2018, the Company entered into the following interest rate swap arrangements to partially mitigate the variability of cash flows due to changes in the Eurodollar rate, specifically related to interest payments on our term loans under the 2018 Credit Agreement:



Trade date	April 6, 2018			May 17, 2018			May 17, 2018			May 17, 2018
Notional amount (in millions)	$	500.0		$	200.0		$	300.0		€	317.0
Term (years)	5			7			3			7
Effective date	4/30/2018			6/29/2018			6/29/2018			6/29/2018

Floating rate	1-month LIBOR			1-month LIBOR			1-month LIBOR			1-month EURIBOR

The interest rate swaps were not designated as hedges and, therefore, do not qualify for hedge accounting. Accordingly, the interest rate swaps are adjusted to fair value through earnings on the consolidated statement of operations as other expense, net.

The fair value of the interest rate swaps at December 31, 2019 and December 31, 2018 were as follows (in millions):



					Fair Value
					December 31, 2019					December 31, 2018
Derivative Instrument	Aggregate Notional Amount		Effective Date	Maturity Date	Asset Derivatives		Liability Derivatives			Asset Derivatives		Liability Derivatives
Interest rate swap	$	500.0	4/30/2018	4/30/2023	$	—	$	(18.2	)	$	—	$	(4.4	)
Interest rate swap	$	200.0	6/29/2018	5/31/2025	—		(15.3		)	—		(6.9		)
Interest rate swap	$	300.0	6/29/2018	6/30/2021	—		(5.8		)	—		(2.8		)

					$	—	$	(53.5	)	$	—	$	(22.4	)

The Company records the fair value of interest rate swaps in its consolidated balance sheets within prepaid expenses and other current assets when in an asset position and within accrued expenses and other current liabilities when in a liability position. Due to the change in fair value of its interest rate swaps, the Company recognized a loss of $31.4 million and $22.4 million in other expense, net for the years ended December 31, 2019 and 2018, respectively.

7.875% Senior Unsecured Notes

Each offering was treated as a single series of debt securities. The 7.875% Senior Unsecured Notes have identical terms other than the issuance date and offering price. The 7.875% Senior Unsecured Notes were issued at a combined premium of $16.5 million.

The 7.875% Senior Unsecured Notes are guaranteed by the Company’s domestic subsidiaries that guarantee the Company’s obligations under the U.S. Term Loan Facility and the Revolving Line of Credit Facility, but not by any of the Company’s foreign subsidiaries.
