DEBT

As of June 30, 2018, a substantial portion of the Company's assets, principally aircraft, certain route authorities and airport slots, was pledged under various loan and other agreements. As of June 30, 2018, UAL and United were in compliance with their respective debt covenants. In May 2018, the Company's Amended and Restated Credit and Guaranty Agreement (as amended, the "2017 Credit Agreement") was amended to reduce the interest rate on the term loan by 0.25%. As of June 30, 2018, United had its entire capacity of $2.0 billion available under the revolving credit facility of the 2017 Credit Agreement.

EETCs. In February and May 2018, United created three new EETC pass-through trusts, each of which issued pass-through certificates. The proceeds of the issuance of the pass-through certificates are used to purchase equipment notes issued by United and secured by its aircraft. The Company records the debt obligation upon issuance of the equipment notes rather than upon the initial issuance of the pass-through certificates. The pass-through certificates represent fractional undivided interests in the respective pass-through trusts and are not obligations of United. The payment obligations under the equipment notes are those of United. Proceeds received from the sale of pass-through certificates are initially held by a depositary in escrow for the benefit of the certificate holders until United issues equipment notes to the trust, which purchases such notes with a portion of the escrowed funds. These escrowed funds are not guaranteed by United and are not reported as debt on our consolidated balance sheet because the proceeds held by the depositary are not United's assets. Certain details of the pass-through trusts with proceeds received from issuance of debt in 2018 are as follows (in millions, except stated interest rate):
