Revolving Credit and Term Loan Agreement In June 2013, the company amended and extended its existing credit facility. The amended credit agreement matures in June 2018 (the “Maturity Date”) and provides for a $900 million, five-year credit facility (“credit facility”) consisting of a (i) $600 million revolving credit facility (the “revolver”) and a (ii) $300 million term loan facility (“term loan”). Borrowings under the credit facility are unsecured and bear interest at the company’s option at (i) the greater of prime or the federal funds rate plus 0.25 to 1.00%, or (ii) Eurodollar rates, plus margins ranging from 1.25 to 2.00% based on the company’s consolidated funded debt to capitalization ratio. Commitment fees on the unused portion of the facilities range from 0.15 to 0.30% based on the company’s funded debt to total capitalization ratio. The credit facility requires that the company maintain a ratio of consolidated debt to consolidated total capitalization that does not exceed 55%, and maintain a consolidated interest coverage ratio (essentially consolidated earnings before interest, taxes, depreciation and amortization, or EBITDA, for the four prior fiscal quarters to consolidated interest charges, including capitalized interest, for such period) of not less than 3.0 to 1.0. All other terms, including the financial and negative covenants, are customary for facilities of its type and consistent with the prior agreement in all material respects. The company had $300 million in term loan borrowings and $20 million of revolver borrowings outstanding at March 31, 2015 (whose fair value approximates the carrying value because the borrowings bear interest at variable rates). The company had $580 million available under the revolver at March 31, 2015. Senior Debt Notes The determination of fair value includes an estimated credit spread between our long term debt and treasuries with similar matching expirations. The credit spread is determined based on comparable publicly traded companies in the oilfield service segment with similar credit ratings. These estimated fair values are based on Level 2 inputs. September 2013 Senior Notes On September 30, 2013, the company executed a note purchase agreement for $500 million and issued $300 million of senior unsecured notes to a group of institutional investors. The company issued the remaining $200 million of senior unsecured notes on November 15, 2013. A summary of these outstanding notes at March 31, is as follows:

The terms of the notes require that the company maintain a ratio of consolidated debt to consolidated total capitalization that does not exceed 55%. September 2010 Senior Notes In fiscal 2011, the company completed the sale of $425 million of senior unsecured notes. A summary of the aggregate amount of these outstanding notes at March 31, is as follows:
(In thousands, except weighted average data) |  |  | 2015 |  |  |  | 2014 |  |  |

The terms of the notes require that the company maintain a ratio of consolidated debt to consolidated total capitalization that does not exceed 55%. Included in accumulated other comprehensive income at March 31, 2015 and 2014, is an after-tax loss of $1.8 million ($2.6 million pre-tax), and $2.4 million ($3.7 million pre-tax), respectively, relating to the purchase of interest rate hedges, which are cash flow hedges, in July 2010 in connection with the September 2010 senior notes offering. The interest rate hedges settled in August 2010 concurrent with the pricing of the senior unsecured notes. The hedges met the effectiveness criteria and their acquisition costs are being amortized to interest expense over the term of the individual notes matching the term of the hedges to interest expense. Notes totaling $42.5 million will mature in December 2015 but are not classified as current maturities of long-term debt because the company has the ability, if necessary, to fund this maturity with its credit facility.

The multiple series of notes were originally issued with maturities ranging from seven to 12 years. These notes can be retired in whole or in part prior to maturity for a redemption price equal to the principal amount of the notes redeemed plus a customary make-whole premium. The terms of the notes require that the company maintain a ratio of consolidated debt to consolidated total capitalization that does not exceed 55%. Notes totaling $35 million will mature in July 2015 but are not classified as current maturities of long-term debt because the company has the ability, if necessary, to fund this maturity with its credit facility.

In January 2014, the loan was amended to, among other things, change the interest rate to a fixed rate equal to 3.88% plus a premium based on Tidewater’s funded indebtedness to capitalization ratio (currently equal to 1.50% for a total all-in rate of 5.38%), change the borrower, change the export creditor guarantor, and to replace the vessel security with a company guarantee.

Troms Offshore had 45 million NOK, or approximately $5.6 million, outstanding in floating rate debt at March 31, 2015 (whose fair value approximates the carrying value because the borrowings bear interest at variable NIBOR rates plus a margin). Troms Offshore also had 436.9 million NOK, or $54.4 million, of outstanding fixed rate debt at March 31, 2015, which has an estimated fair value of 435 million NOK, or $54.1 million as well as $29.5 million, of U.S. dollar denominated outstanding fixed rate debt at March 31, 2015, which has an estimated fair value of $29.5 million.

During the second quarter of fiscal 2014, the company repaid prior to maturity 500 million Norwegian Kroner (NOK) denominated (approximately $82.1 million) public bonds (plus accrued interest) that had been issued by Troms Offshore in April 2013.
