[1] As discussed in more detail in Note 5, during the six months ended June 30, 2017, we received proceeds from two subordinated promissory notes issued by our largest shareholder. Proceeds from such borrowings were remitted directly to our lender to reduce the outstanding balance under our senior revolving credit facility.

[2] Interest and other charges incurred pursuant to our senior revolving credit facility are calculated periodically and added to the principal balance of the loan. As such, we do not make cash payments for interest charges related to this facility.
