5. Long Term Debt

At September 30, 2013, notes payable consists of loans totaling $744.3 million, payable over periods of approximately four months to nine years with interest rates varying between approximately 3.2% and 5.5% (excluding the effect of our interest rate derivative instruments).

Our significant debt instruments are discussed below:

At September 30, 2013, we had a $450.0 million revolving credit facility to finance the acquisition of aircraft engines for lease as well as for general working capital purposes. We closed on this facility on November 18, 2011 and the proceeds of the facility, net of $3.3 million in debt issuance costs, was used to pay off the balance remaining from our prior revolving facility. On June 18, 2013, we increased this revolving credit facility to $450.0 million from $430.0 million. As of September 30, 2013 and December 31, 2012, $138.0 million and $148.0 million was available under this facility, respectively. The revolving credit facility ends in November 2016. Based on the Company’s debt to equity ratio of 3.80, as calculated under the terms of the revolving credit facility at June 30, 2013, the interest rate on this facility is LIBOR plus 3.00% as of September 30, 2013. 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 will remain on the Company’s balance sheet. A portfolio of 79 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 Servicing Agreement and Administrative Agency Agreement previously filed by the Company as exhibits to, and described in, its Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2005 relating to WEST were terminated. 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 September 30, 2013 and December 31, 2012, $375.0 million and $386.7 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. With this acquisition, WOLF is consolidated for financial statement presentation purposes. Two term notes with an original principal amount of $36.0 million, with a current balance outstanding of $31.5 million as of September 30, 2013, are included in Notes payable. The two term notes are non-recourse to the Company, have a maturity date of May 2017 and interest is payable at one-month LIBOR plus 4.0%.

The assets of WOLF are not available to satisfy our obligations or any of our affiliates other than the obligations specific to WOLF. WOLF’s ability to make distributions to the Company is subject to the prior payments of all of its debt and other obligations. Under WOLF, cash related to parts sale and leasing of engine assets is collected in a restricted account and used to pay certain operating expenses, service the debt, and upon full debt repayment are distributed to the Company.

On September 28, 2012, we closed on a loan for a five year term totaling $8.7 million. Interest is payable monthly at a fixed rate of 5.50% and principal 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 $8.3 million and $8.6 million as of September 30, 2013 and December 31, 2012, respectively.

On September 30, 2011, we closed on a loan for a three year term totaling $4.0 million. Interest is payable at a fixed rate of 3.94% and principal and interest is paid monthly. The loan is secured by our corporate aircraft. The funds were used to refinance the loan for our corporate aircraft. The balance outstanding on this loan is $1.3 million and $2.3 million as of September 30, 2013 and December 31, 2012, respectively.

On January 11, 2010, we closed on a loan for a four year term totaling $22.0 million, the proceeds of which were used to pay down our revolving credit facility. Interest is payable at a fixed rate of 4.50% and principal and interest is paid quarterly. The loan is secured by three engines. The balance outstanding on this loan is $16.2 million and $17.3 million as of September 30, 2013 and December 31, 2012, respectively.

Virtually all of the debt instruments above have covenant requirements such as minimum tangible net worth, maximum balance sheet leverage and various interest coverage ratios. 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 September 30, 2013.

At September 30, 2013, we are in compliance with the covenants specified in the revolving credit facility Credit Agreement, including the Interest Coverage Ratio requirement of at least 2.50 to 1.00, and the Total Leverage Ratio requirement to remain below 4.75 to 1.00. At September 30, 2013, the Company’s calculated Minimum Consolidated Tangible Net Worth exceeded the minimum required amount of $191.1 million. 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 September 30, 2013, we are in compliance with the covenants specified in the WEST II indenture and servicing agreement.

At September 30, 2013 and 2012, one-month LIBOR was 0.18% and 0.21%, respectively.
