Short-term deposits represent down payment amounts paid to suppliers for material purchases. Certain Asian suppliers require us to pay a deposit prior to manufacturing and/or shipping products to us. The short-term debt acquisition costs consist of the balance of the annual facility fee and the short-term portion of the legal and professional fees we incurred in connection with the revolving credit facility we entered into on December 11, 2018. The annual facility fee of $50 thousand was paid on the date the credit facility was signed and is being amortized on a straight-line basis over one year. The debt acquisition costs are being amortized on a straight-line basis over three years, which is the length of the credit facility. The long-term portion of the debt acquisition costs are included in the Consolidated Balance Sheets under the caption, “Other assets.” For additional information on the revolving credit facility, please refer to Note 9, “Debt.”
