| Balance Sheet Components | BALANCE SHEET COMPONENTS Accounts Receivable, Net Accounts receivable are contract assets that arise from the performance of our performance obligation pursuant to our contracts with our customers and represent our unconditional right to payment for the satisfaction of our performance obligations.

Conditions that would trigger an impairment assessment include, but are not limited to, past, current, or expected cash flow or operating losses associated with the asset. There were no such triggering events requiring an impairment assessment of other intangible assets during the nine months ended September 30, 2019. Goodwill Goodwill resulted from the Acquisition, whereby we recorded goodwill of $18,407 . Goodwill is not amortized; however, we review goodwill for impairment annually and whenever events or changes in circumstances indicate that the fair value of the reporting unit may be less than it's carrying value. Conditions that would trigger an impairment assessment include, but are not limited to, a significant adverse change in our business climate or a current period operating or cash flow loss combined with a history of operating or cash flow losses or a projection or forecast that demonstrates continued losses or adverse changes in legal factors, regulation or business environment. There were no such triggering events requiring a goodwill impairment assessment during the nine months ended September 30, 2019. We perform our annual impairment assessment for goodwill on November 30 of each year.

Any increase in deferred revenues is driven by cash payments received or due in advance of satisfying our performance obligation pursuant to the contract with the customer. Any decrease in deferred revenues is due to the recognition of revenue related to satisfying our performance obligation. The changes in deferred revenue and the liability for warranty returns are as follows: Nine Months Ended September 30, 2019 2018 Deferred revenue: Balance at beginning of period $ 96 $ 418 Revenue deferred 401 580 Revenue recognized (365 ) (864 ) Balance at end of period $ 132 $ 134 Liability for warranty returns: Balance at beginning of period $ 13 $ 17 Charge-offs (2 ) (10 ) Provision (1 ) 8 Balance at end of period $ 10 $ 15 Short-Term Line of Credit On December 21, 2010, we entered into a Loan and Security Agreement with Silicon Valley Bank (the "Bank"), which was amended on December 14, 2012, December 4, 2013, December 18, 2015, December 15, 2016, July 21, 2017, December 21, 2017 and December 18, 2018 (as amended, the "Revolving Loan Agreement"). The Revolving Loan Agreement provides a secured working capital-based revolving line of credit (the "Revolving Line") in an aggregate amount of up to the lesser of (i) $10,000 , or (ii) $1,000 plus 80% of eligible domestic accounts receivable and certain foreign accounts receivable. The Revolving Line has a maturity date of December 27, 2019. In addition, the Revolving Loan Agreement provides for non-formula advances of up to $10,000 which may be made solely during the last five business days of any fiscal month or quarter and which must be repaid by us on or before the fifth business day after the applicable fiscal month or quarter end. Due to their repayment terms, non-formula advances do not provide us with usable liquidity. The Revolving Loan Agreement, as amended, contains customary affirmative and negative covenants as well as customary events of default. The occurrence of an event of default could result in the acceleration of our obligations under the Revolving Loan Agreement, as amended, and an increase to the applicable interest rate, and would permit the Bank to exercise remedies with respect to its security interest. As of September 30, 2019, we were in compliance with all of the terms of the Revolving Loan Agreement, as amended. As of September 30, 2019 and December 31, 2018, we had no |
