Going Concern	NOTE 2—Going Concern At December 31, 2017, we had a credit agreement with a bank group (see NOTE 6 — Credit Facility). The maximum borrowing limit under the facility was $35,000,000 as of December 31, 2017 and the facility expires September 30, 2018. At December 31, 2017, there was $19,900,000 outstanding under the facility. The credit facility is classified as a current liability as of December 31, 2017 in our consolidated balance sheets as the facility expires on September 30, 2018. We will seek to refinance or extend the maturity of this obligation prior to its expiration date; however, there is no assurance that we will be able to execute this refinancing or extension or, if we are able to refinance or extend this obligation, that the terms of such refinancing or extension would be as favorable as the terms of our existing credit facility. These factors raise substantial doubt about our ability to continue as a going concern. The accompanying financial statements have been prepared assuming that we will continue as a going concern and do not include any adjustments that might result from the outcome of this uncertainty. The report from our independent registered public accountants, KPMG LLP, dated March 1, 2018, includes an explanatory paragraph related to our ability to continue as a going concern.
