GeoSouthern Debt In December 2013, in conjunction with the planned GeoSouthern acquisition, Devon issued $2.25 billion aggregate principal amount of fixed and floating rate senior notes resulting in cash proceeds of approximately $2.2 billion, net of discounts and issuance costs.
The floating rate senior notes due in 2015 bear interest at a rate equal to three-month LIBOR plus 0.45 percent, which rate will be reset quarterly.
The floating rate senior notes due in 2016 bears interest at a rate equal to three-month LIBOR plus 0.54 percent, which rate will be reset quarterly.
The schedule below summarizes the key terms of these notes (in millions).
## Table 0 ##
(1) The 1.20% $650 million note due December 15, 2016 was redeemed on November 13, 2014.
The senior notes were classified as short-term debt on Devon’s consolidated balance sheet as of December 31, 2013 due to certain redemption features in the event that the GeoSouthern acquisition was not completed on or prior to June 30, 2014.
On February 28, 2014, the GeoSouthern acquisition closed and thus the senior notes were subsequently classified as long-term debt.
Additionally, during December 2013, Devon entered into a term loan agreement with a group of major financial institutions pursuant to which Devon could draw up to $2.0 billion to finance, in part, the GeoSouthern acquisition and to pay transaction costs.
In February 2014, Devon drew the $2.0 billion of term loans for the GeoSouthern transaction, and the amount was subsequently repaid on June 30, 2014 with the Canadian divestiture proceeds that were repatriated to the U. S.  in June 2014, at which point the term loan was terminated.
PRUDENTIAL FINANCIAL, INC.  Notes to Consolidated Financial Statements The master trust’s payment obligations under each of the asset-backed notes are secured by corresponding payment obligations of a third-party financial institution and a portfolio of specified assets that have an aggregate value at least equal to the principal amount of the applicable asset-backed note.
The principal amount of each asset-backed note is payable to PRIAC in cash at any time upon demand by PRIAC or, if not earlier paid, at maturity.
Each of the limited recourse notes obligates Prudential Financial to reimburse the applicable third-party financial institution for any principal payments received on the corresponding asset-backed note, but there is no obligation to reimburse any portion of a principal payment that is needed by PRIAC to pay then current claims to its policyholders.
Each limited recourse note bears interest at a rate equal to the rate on the corresponding asset-backed note, plus an amount representing fees payable to the applicable third-party financial institution.
As of December 31, 2015, no principal payments have been received or are currently due on the asset-backed notes and, as a result, there was no payment obligation under the limited recourse notes.
Accordingly, the notes are not reflected in the Company’s Consolidated Financial Statements as of December 31, 2015.
