Our significant debt instruments are discussed below:

At March 31, 2012, we had a $345.0 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 new facility, net of $3.3 million in debt issuance costs, was used to pay off the balance remaining from our prior revolving facility. As of March 31, 2012, $116.0 million was available under this facility. The revolving facility ends in November 2016. Based on the Company's debt to equity ratio of 2.97 as calculated under the terms of the revolvers credit facility, the interest rate on this facility decreased to LIBOR plus 2.5% as of March 31, 2012. Under the revolver facility, all subsidiaries except Willis Engine Securitization Trust ("WEST") and WEST Engine Funding LLC 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 30, 2011, we closed on a term 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 $3.3 million as of March 31, 2012.

On January 11, 2010, we closed on a new term loan for a four year term totaling $22.0 million. 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 funds were used to pay down our revolving credit facility. The balance outstanding on this facility is $18.4 million as of March 31, 2012.

At March 31, 2012, we had $425.2 million of WEST term notes outstanding. Included in the term notes outstanding are the Series 2007-A2 and Series 2007-B2 warehouse notes that converted to term notes effective February 14, 2011. The term notes are divided into $96.0 million Series 2005-A1 notes, $159.1 million Series 2007-A2 notes, $23.1 million Series 2007-B2 notes and $147.0 million Series 2008-A1 notes.

The Series 2007-A2 and 2007-B2 notes expected maturity is January 2024 and January 2026, respectively.

The Series 2008-B1 notes were issued on March 28, 2008 in the original principal amount of $20.3 million. On June 30, 2008, we purchased the WEST Series 2008-B1 notes for $19.8 million (the unpaid principal amount of the 2008-B1 notes at that date) with the proceeds of a $20.0 million term loan made by an affiliate of the prior note holder. This term loan is secured by a pledge of the WEST Series 2008-B1 notes to the lender. The term loan was originally for a term of two years with maturity on July 1, 2010 with no amortization with all amounts due at maturity. The term loan has since been amended and extended several times. On March 29, 2012, the Company further extended the maturity date from June 30, 2012 to December 31, 2012. The interest rate remains at one-month LIBOR plus 4.00% and the loan continues to amortize on a monthly basis, with a $13.0 million bullet payment required at the December 31, 2012 maturity date. The balance outstanding on this term loan is $13.9 million as of March 31, 2012.

On January 18, 2011, we purchased the WEST Series 2005-B1 notes for $17.9 million (the unpaid principal amount of the 2005-B1 notes at that date) with the proceeds of a term loan made by the bank which was the prior note holder. This term loan is secured by a pledge of the WEST Series 2005-B1 notes to the lender. The interest rate on this term loan is one-month LIBOR plus a margin of 3.00%. The term of this loan is five years and the loan amortization is consistent with the amortization on the underlying WEST Series 2005-B1 notes, with a bullet payment required at the end of the five year term. The balance outstanding on this term loan is $15.7 million as of March 31, 2012.

WEST'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's maintenance of adequate reserves and capital. Under WEST, 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, maintenance reserve payments and lease security deposits are accumulated in restricted accounts and are not available for general use. Cash from maintenance reserve payments are held in the restricted cash account and are subject to a minimum balance established annually based on an engine portfolio maintenance reserve study provided by a third party. Any excess maintenance reserve amounts remain within the restricted cash accounts and are utilized for the purchase of new engines.

The assets of WEST, WEST Engine Funding LLC and any associated Owner Trust are not available to satisfy the Company's obligations or the obligations of any of our affiliates. WEST is consolidated for financial statement presentation purposes.

The Company and its subsidiaries are required to comply with various financial covenants 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 March 31, 2012.

At each of March 31, 2012 and 2011, one-month LIBOR was 0.24%.
