As further discussed in Note 2 — Notes Payable to Banks, AWR (parent) has access to a $150.0 million syndicated credit facility. AWR (parent) borrows under this facility and provides funds to its subsidiaries, in support of their operations. Any amounts owed to AWR (parent) for borrowings under this facility are reflected as inter-company receivables on the condensed balance sheets.  The interest rate charged to the subsidiaries is sufficient to cover AWR (parent)’s interest cost under the credit facility.

In October 2015, AWR issued interest bearing promissory notes (the "Notes") to GSWC and ASUS for $40 million and $10 million, respectively, which expire on May 23, 2018. Under the terms of the Notes, AWR may borrow from GSWC and ASUS amounts up to $40 million and $10 million, respectively, for working capital purposes. AWR agrees to pay any unpaid principal amounts outstanding under these notes, plus accrued interest. As of December 31, 2017 and 2016, there were no amounts outstanding under these notes.
