4. Long Term Debt

At June 30, 2015, notes payable consists of loans totaling $861.0 million, payable over periods of approximately 2.2 to 9.1 years with interest rates varying between approximately 2.4% and 5.5%.

At June 30, 2015, we had a revolving credit facility to finance the acquisition of aircraft engines for lease as well as for general working capital purposes, with the amounts drawn under the facility not to exceed that which is allowed under the borrowing base as defined by the credit agreement. On June 4, 2014, we entered into a Second Amended and Restated Credit Agreement which increased this revolving credit facility to $700.0 million from $450.0 million and extended the maturity date by five years to June 2019. Debt issuance costs totaling $4.9 million were incurred related to the new facility. As of June 30, 2015 and December 31, 2014, $205.0 million and $270.0 million were available under this facility, respectively. On a quarterly basis, the interest rate is adjusted based on the Company’s leverage ratio, as calculated under the terms of the revolving credit facility. Based on the Company’s leverage ratio of 4.14 at March 31, 2015, the interest rate on this facility is one-month LIBOR plus 2.75% as of June 30, 2015. Under the revolving credit facility, all subsidiaries except WEST II and WOLF jointly and severally guarantee payment and performance of the terms of the loan agreement. The guarantee would be triggered by a default under the agreement.

On September 17, 2012, we closed an asset-backed securitization (“ABS”) through a newly-created, bankruptcy-remote, Delaware statutory trust, Willis Engine Securitization Trust II, or “WEST II”, of which the Company is the sole beneficiary. WEST II issued and sold $390 million aggregate principal amount of Class 2012-A Term Notes (the “Notes”) and received $384.9 million in net proceeds. We used these funds, net of transaction expenses and swap termination costs, in combination with our revolving credit facility to pay off the prior WEST notes totaling $435.9 million. At closing, 22 engines were pledged as collateral from WEST to the Company’s revolving credit facility, which provided the remaining funds to pay off the WEST notes.

The assets and liabilities of WEST II are included on the Company’s balance sheet. The current portfolio of 65 commercial jet aircraft engines and leases thereof secures the obligations of WEST II under the ABS. The Notes have no fixed amortization and are payable solely from revenue received by WEST II from the engines and the engine leases, after payment of certain expenses of WEST II. The Notes bear interest at a fixed rate of 5.50% per annum. The Notes may be accelerated upon the occurrence of certain events, including the failure to pay interest for five business days after the due date thereof. The Notes are expected to be paid 10 years from the issuance date by September 17, 2022. The legal final maturity of the Notes is September 15, 2037.

In connection with the transactions described above, effective September 17, 2012, the Company entered into a Servicing Agreement and Administrative Agency Agreement with WEST II to provide certain engine, lease management and reporting functions for WEST II in return for fees based on a percentage of collected lease revenues and asset sales. Because WEST II is consolidated for financial statement reporting purposes, all fees eliminate upon consolidation.

At June 30, 2015 and December 31, 2014, $327.8 million and $351.9 million of WEST II term notes were outstanding, respectively. The assets of WEST II are not available to satisfy our obligations or any of our affiliates other than the obligations specific to WEST II. WEST II is consolidated for financial statement presentation purposes. WEST II’s ability to make distributions and pay dividends to the Company is subject to the prior payments of its debt and other obligations and WEST II’s maintenance of adequate reserves and capital. Under WEST II, cash is collected in a restricted account, which is used to service the debt and any remaining amounts, after debt service and defined expenses, are distributed to the Company. Additionally, a portion of maintenance reserve payments and all lease security deposits are accumulated in restricted accounts and are available to fund future maintenance events and to secure lease payments, respectively. Cash from maintenance reserve payments are held in the restricted cash account equal to the maintenance obligations projected for the subsequent six months, and are subject to a minimum balance of $9.0 million.

On March 25, 2015, we paid off the $23.1 million balance of the two term notes associated with the WOLF assets at a 5% discount. This transaction resulted in the recording of a $1.2 million gain on debt extinguishment which has been included in our statement of operations for the six months ended June 30, 2015.

On July 16, 2014, we closed on a loan for a ten year term totaling $13.4 million. During the second quarter of 2015, we closed on two additional loans totaling $4.7 million, repayable over the same ten year term. The interest is payable at fixed rates ranging from 2.60% to 2.97% for the initial five years of the loan term and principal and interest is paid monthly. The loans provided 100% of the funding for the purchase of a corporate aircraft and subsequent modifications and upgrades. The balance outstanding on these loans is $17.0 million and $12.9 million as of June 30, 2015 and December 31, 2014, respectively.

On January 10, 2014, we extended the term of an existing loan that was scheduled to mature on January 11, 2014. The loan has a term of 4 years with a maturity date of January 11, 2018. Interest is payable at one-month LIBOR plus 2.25% and principal and interest is paid quarterly. The loan is secured by three engines. The balance outstanding on this loan is $13.8 million and $14.5 million as of June 30, 2015 and December 31, 2014, respectively.

On September 28, 2012, we closed on a loan for a five year term totaling $8.7 million. Interest is payable at a fixed rate of 5.50% and principal and interest is paid quarterly. The loan is secured by one engine. The funds were used to purchase the engine secured under the loan. The balance outstanding on this loan is $7.4 million and $7.7 million as of June 30, 2015 and December 31, 2014, respectively.

One-month LIBOR was 0.19% and 0.17% at June 30, 2015 and December 31, 2014, respectively.
