The fair value of our debt measured utilizing Level 2 inputs was based on quoted market prices for identical instruments and if unavailable, quoted market prices of similar instruments. For debt with original maturity or revolving period of eighteen months or less par value is considered to be a reasonable estimate of fair value. The fair value of our debt measured utilizing Level 3 inputs was based on the discounted future net cash flows expected to be settled using current risk-adjusted rates.

Secured Debt Most of the secured debt was issued by VIEs and is repayable only from proceeds related to the underlying pledged assets. Refer to Note 8 - "Variable Interest Entities" for further discussion.

Compliance with Debt Covenants Several of our revolving credit facilities require compliance with certain financial and operational covenants as well as regular reporting to lenders, including providing certain subsidiary financial statements. Certain of our secured debt agreements also contain various covenants, including maintaining portfolio performance ratios as well as limits on deferment levels. Our unsecured senior notes contain covenants including limitations on our ability to incur certain liens. At June 30, 2017, we were in compliance with these debt covenants.
