UNSECURED COMMITTED LINE OF CREDIT – On September 21, 2018, we entered into a Third Amended and Restated Credit and Guarantee Agreement (2018 CLOC), which amended and restated our Second Amended and Restated Credit and Guarantee Agreement (2017 CLOC), extending the scheduled maturity date from September 22, 2022 to September 21, 2023. Other material terms remain unchanged from our 2017 CLOC. The 2018 CLOC provides for an unsecured senior revolving credit facility in the aggregate principal amount of $2.0 billion, which includes a $200.0 million sublimit for swingline loans and a $50.0 million sublimit for standby letters of credit. We may request increases in the aggregate principal amount of the revolving credit facility of up to $500.0 million, subject to obtaining commitments from lenders and meeting certain other conditions. The 2018 CLOC will mature on September 21, 2023,

unless extended pursuant to the terms of the 2018 CLOC, at which time all outstanding amounts thereunder will be due and payable. The 2018 CLOC includes an annual facility fee, which will vary depending on our then current credit ratings.

The 2018 CLOC is subject to various conditions, triggers, events or occurrences that could result in earlier termination and contains customary representations, warranties, covenants and events of default, including, without limitation: (1) a covenant requiring the Company to maintain a debt-to-EBITDA ratio calculated on a consolidated basis of no greater than (a) 3.50 to 1.00 as of the last day of each fiscal quarter ending on April 30, July 31, and October 31 of each year and (b) 4.50 to 1.00 as of the last day of each fiscal quarter ending on January 31 of each year; (2) a covenant requiring us to maintain an interest coverage ratio (EBITDA-to-interest expense) calculated on a consolidated basis of not less than 2.50 to 1.00 as of the last date of any fiscal quarter; and (3) covenants restricting our ability to incur certain additional debt, incur liens, merge or consolidate with other companies, sell or dispose of assets (including equity interests), liquidate or dissolve, engage in certain transactions with affiliates or enter into certain restrictive agreements. The 2018 CLOC includes provisions for an equity cure which could potentially allow us to independently cure certain defaults. Proceeds under the 2018 CLOC may be used for working capital needs or for other general corporate purposes. We were in compliance with these requirements as of October 31, 2018.

We had no outstanding balance under the 2018 CLOC as of October 31, 2018, and amounts available to borrow were limited by the debt-to-EBITDA covenant to approximately $1.7 billion as of October 31, 2018.

In October 2018, we exercised a purchase option to acquire an office building previously recorded as a capital lease.

The estimated fair value of our long-term debt as of October 31, 2018 and 2017 and April 30, 2018 totaled $1.5 billion, $1.6 billion and $1.5 billion, respectively.
