The interest rate margins applicable to the Term Loan Facility were decreased by 25 basis points to LIBOR plus 2.75% with a minimum LIBOR of 1.0% . In addition, the amended and restated Credit Agreement removed the fixed charge coverage ratio covenant and replaced such covenant with a springing senior secured leverage ratio maintenance requirement applicable only to the Revolver, increased certain lien and debt baskets, and removed certain covenants related to collateral. The terms of the Term Loan Facility require the Company to make quarterly principal payments of $4.1 million plus an annual payment of up to 50% of excess cash flow, as determined in accordance with the Credit Agreement (no such payment was required during the three and six months ended December 31, 2015 or 2014 ).

The Credit Agreement contains customary events of default, including among others, non-payment of principal, interest, or other amounts when due, inaccuracy of representations and warranties, breach of covenants, cross default to certain other indebtedness, insolvency or inability to pay debts, bankruptcy, or a change of control. The Credit Agreement also contains a covenant, applicable only to the Revolver, that the Company maintain a senior secured leverage ratio below 5.25:1.00 at any time when the aggregate principal amount of loans outstanding under the Revolver is greater than 35% of the commitments under the Revolver. The indenture governing the 2020 Unsecured Notes limits any increase in the Company’s secured indebtedness (other than certain forms of secured indebtedness expressly permitted under such indenture) to a pro forma secured debt ratio of 4.50 times the Company’s previous quarter’s annualized modified EBITDA, as defined in the indenture, and limits the Company’s incurrence of additional indebtedness to a total indebtedness ratio of 5.25 times the previous quarter’s annualized modified EBITDA. The indentures governing the 2023 Unsecured Notes and the 2025 Unsecured Notes limit any increase in the Company’s secured indebtedness (other than certain forms of secured indebtedness expressly permitted under such indentures) to a pro forma secured debt ratio of 4.50 times the Company’s previous quarter’s annualized modified EBITDA (as defined in such indentures), and limit the Company’s incurrence of additional indebtedness to a total indebtedness ratio of 6.00 times the previous quarter’s annualized modified EBITDA. The Company was in compliance with all covenants associated with its debt agreements as of December 31, 2015 . Guarantees The Notes are fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis by all of the Company’s current and future domestic restricted subsidiaries. The Notes were co-issued with Zayo Capital, which does not have independent assets or operations. Debt issuance costs In connection with the Credit Agreement (and subsequent amendments thereto), and the various Notes offerings, the Company incurred debt issuance costs of $99.5 million (net of extinguishments). These costs are being amortized to interest expense over the respective terms of the underlying debt instruments using the effective interest method, unless extinguished earlier, at which time the related unamortized costs are to be immediately expensed. Unamortized debt issuance costs of $23.2 million associated with the Company’s previous indebtedness were recorded as part of the loss on extinguishment of debt during Fiscal 2015 . The balance of debt issuance costs as of December 31, 2015 and June 30, 2015 was $66.2 million and $71.0 million, net of accumulated amortization of $33.3 million and $28.3 million, respectively. The amortization of debt issuance costs is included on the condensed consolidated statements of cash flows within the caption “Non-cash interest expense” along with the amortization or accretion of the premium and discount on the Company’s indebtedness and changes in the fair value of the Company’s interest rate derivatives. Interest expense associated with the amortization of debt issuance costs was $2.5 million and $5.0 million for the three and six months ended December 31, 2015 and $3.8 million and $7.5 million during the three and six months ended December 31, 2014 , respectively.

The counterparty will pay to the Company the greater of actual LIBOR or 1.25% . The Company entered into the forward-starting swap arrangements to reduce the risk of increased interest costs associated with potential changes in LIBOR rates. Changes in the fair value of interest rate swaps are recorded in interest expense in the condensed consolidated statements of operations for the applicable period. The fair value of the interest rate swaps of $3.5 million and $4.1 million are included in “Other long term liabilities” in the Company’s condensed consolidated balance sheets as of December 31, 2015 and June 30, 2015 , respectively.

Under the terms of the Fourth Amendment, the Revolver bore interest at LIBOR plus 3.00%, based on the Company’s current leverage ratio, which represented a 50 basis point reduction. The Fourth Amendment also amended certain terms and provisions of the Credit Agreement, including removing the senior secured and total leverage maintenance covenants and increasing the total leverage ratio required to be met in order to incur certain additional indebtedness from 5.00:1.00 to 5.25:1.00 as a multiple of EBITDA (as defined in the Credit Agreement). In connection with the aforementioned amendments, the Company incurred early redemption call premiums of $16.2 million and $16.1 million for the Second Amendment and Fourth Amendment, respectively. The early redemption call premiums were paid with cash on hand to the syndicate of creditors in the Term Loan Facility. Prior to the consummation of the amendments, the Company requested the consent of all creditors holding balances in the Term Loan Facility to the amended terms. $15.3 million and $15.0 million of the early call premium paid to consenting creditors in the Second and Fourth Amendments, respectively, were accounted for as additional debt issuance costs for the modified obligations during the year ended June 30, 2013, which are being amortized over the term of the Term Loan Facility using the effective interest method. The remaining call premium of $0.9 million and $1.1 million associated with the Second and Fourth Amendments, respectively, that was paid to non-consenting creditors has been recorded as a loss on extinguishment of debt on the consolidated statements of operations for the year ended June 30, 2013.

The amended terms represented a downward adjustment of 50 basis points on the interest rate from the Fourth Amendment.

In connection with the Fifth Amendment, the Company did not incur a re-pricing premium. Also, in connection with the Fifth Amendment, the Company recognized an expense during the second quarter of Fiscal 2014 of $1.9 million associated with debt extinguishment costs, including cash expense of $1.0 million related to third party costs and non-cash expense of $0.9 million associated with the write-off of the Company’s unamortized debt issuance costs and discount on the Term Loan Facility accounted for as an extinguishment.
