(8) LONG-TERM DEBT
On September 23, 2016, Roper entered into a five-year $2.5 billion unsecured credit facility, as amended December 2, 2016, (the “2016 Facility”) with JPMorgan Chase Bank, N.A., as administrative agent, and a syndicate of lenders, which replaced its previous $1.85 billion unsecured credit facility dated as of July 27, 2012, as amended as of October 28, 2015 (the “2012 Facility”). The 2016 Facility comprises a five year $2.5 billion revolving credit facility, which includes availability of up to $150.0 for letters of credit. Roper may also, subject to compliance with specified conditions, request term loans or additional revolving credit commitments in an aggregate amount not to exceed $500.0. At December 31, 2019, there were $0.0 of outstanding borrowings under the 2016 Facility.
The 2016 Facility contains affirmative and negative covenants which, among other things, limit Roper’s ability to incur new debt, enter into certain mergers and acquisitions, sell assets and grant liens, make restricted payments (including the payment of dividends on our common stock) and capital expenditures, or change its line of business. Roper is also subject to financial covenants which require the Company to limit its consolidated total leverage ratio and to maintain a consolidated interest coverage ratio. The most restrictive covenant is the consolidated total leverage ratio which is limited to 3.50 to 1.
The 2016 Facility provides that the consolidated total leverage ratio may be increased, no more than twice during the term of the 2016 Facility, to 4.00 to 1 for a consecutive four quarter fiscal period per increase (or, for any portion of such four quarter fiscal period in which the maximum would be 4.25 to 1). In conjunction with the Deltek acquisition in December of 2016, we increased the maximum consolidated total leverage ratio covenant to 4.25 to 1 through June 30, 2017 and 4.00 to 1 through December 31, 2017.
The Company was in compliance with its debt covenants throughout the years ended December 31, 2019 and 2018.

The notes bear interest at a fixed rate and are payable semi-annually in arrears on March 15 and September 15 of each year, beginning March 15, 2020. The net proceeds were used to fund a portion of the purchase of iPipeline Holdings, Inc.

During 2018 a portion of the net proceeds of the 2018 Offering were used to redeem all of the $500.0 of outstanding 2019 Notes. The Company incurred a debt extinguishment charge in connection with the redemption of the 2019 Notes of $15.9, which represents the make-whole premium and unamortized deferred financing costs.
Roper may redeem some or all of these notes at any time or from time to time, at 100% of their principal amount, plus a makewhole premium based on a spread to U.S. Treasury securities.
The Company’s senior notes are unsecured senior obligations of the Company and rank equally in right of payment with all of Roper’s existing and future unsecured and unsubordinated indebtedness. The notes are effectively subordinated to any of its existing and future secured indebtedness to the extent of the value of the collateral securing such indebtedness. The notes are not guaranteed by any of Roper’s subsidiaries and are effectively subordinated to all existing and future indebtedness and other liabilities of Roper’s subsidiaries.
