Virtually all of the above debt requires our ongoing compliance with the covenants of each financing, including debt/equity ratios, minimum tangible net worth and minimum interest coverage ratios, and other eligibility criteria including customer and geographic concentration restrictions. The Company also has certain negative financial covenants such as liens, advances, change in business, sales of assets, dividends and stock repurchase. These covenants are tested quarterly and the Company was in full compliance with all covenant requirements at December 31, 2015.

At December 31, 2015, we are in compliance with the covenants specified in the revolving credit facility, including the Interest Coverage Ratio requirement of at least 2.25 to 1.00, and the Total Leverage Ratio requirement to remain below 5.00 to 1.00. As defined in the revolving credit facility Credit Agreement, the Interest Coverage Ratio is the ratio of Earnings before Interest, Taxes, Depreciation and Amortization and other one-time charges (EBITDA) to Consolidated Interest Expense and the Total Leverage Ratio is the ratio of Total Indebtedness to Tangible Net Worth. At December 31, 2015, we are in compliance with the covenants specified in the WEST II indenture and servicing agreement.

At December 31, 2015, notes payable consists of loans totaling $878.7 million payable over periods of approximately 2.0 years to 8.6 years with interest rates varying between approximately 2.6% and 5.5%. Substantially all of our assets are pledged to secure our obligations to creditors. Our significant debt instruments are discussed below:

At December 31, 2015, we had a revolving credit facility to finance the acquisition of equipment 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 December 31, 2015 and December 31, 2014, $151.0 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 4.46 at December 31, 2015, the interest rate on this facility is one-month LIBOR plus 2.75% as of December 31, 2015. Under the revolving credit facility, all subsidiaries except WEST II 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, 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 will remain on the Company’s balance sheet. The current portfolio of 63 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 in 10 years. 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 December 31, 2015 and 2014, $300.5 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 September 18, 2013, we completed the acquisition of the fifty percent membership interest held by the other joint venture partner in WOLF, with the transaction being accounted for as an asset acquisition. As a result of the transaction, we now own one hundred percent of WOLF. The WOLF assets and liabilities and the results of operations related to the WOLF assets have been included in the accompanying consolidated financial statements as of the acquisition date, September 18, 2013. Two term notes with an original principal amount of $36.0 million, with a balance outstanding of $24.0 million as of December 31, 2014, are included in Notes payable. 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 income for the year ended December 31, 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 $16.1 million and $12.9 million as December 31, 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 $13.1 million and $14.5 million as of December 31, 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. On July 10, 2015, we paid off the $7.4 million loan balance that was secured by one engine.
