In March 2020, WLFC and its direct, wholly-owned subsidiary Willis Engine Structured Trust V (“WEST V”) (formerly known as Willis Engine Securitization Trust II (“WEST II”)), closed its offering of $366.2 million aggregate principal amount of fixed rate notes (the “Notes”). The Notes were issued in three series, with the Series A Notes issued in an aggregate principal amount of $303.0 million, the Series B Notes issued in an aggregate principal amount of $42.1 million and the Series C Notes issued in an aggregate principal amount of $21.1 million. The Notes are secured by, among other things, WEST V’s direct and indirect ownership interests in a portfolio of 54 aircraft engines and three airframes, including 25 aircraft engines and three airframes which WEST V will acquire from WLFC pursuant to an asset purchase agreement.

The Series A Notes have a fixed coupon of 3.228%, an expected maturity of approximately eight years and a final maturity date of March 15, 2045, the Series B Notes have a fixed coupon of 4.212%, an expected maturity of approximately eight years and a final maturity date of March 15, 2045 and the Series C Notes have a fixed coupon of 6.657%, an expected maturity of approximately eight years and a final maturity date of March 15, 2045. The Series A Notes were issued at a price of 99.99859% of par, the Series B Notes were issued at a price of 99.99493% of par and the Series C Notes were issued at a price of 99.99918% of par. Principal on the Notes is payable monthly to the extent of available cash in accordance with a priority of payments included in the indenture for the Notes. Proceeds from asset sales by WEST V will be used, at WEST V's election subject to certain conditions, to reduce WEST V's debt or to acquire other engines or airframes.

The Company recognized a $4.7 million loss on debt extinguishment upon the repayment of the WEST II Series A 2012 term notes in March 2020.

Virtually all of the above debt requires ongoing compliance with certain financial covenants, 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 is required to comply with certain negative financial covenants such as prohibitions on liens, advances, change in business, sales of assets, dividends and stock repurchases. These covenants are tested either monthly or quarterly and the Company was in full compliance with all financial covenant requirements at June 30, 2020.
