Liquidity	(2) Liquidity During 2016, the Company incurred a net loss of approximately $4.2 million. In addition as of December 31, 2016, as discussed in Note 10 Long-Term Debt, the Company was in default with various covenants included in its credit facility with Prosperity Bank. Each of these defaults was cured either through a waiver or an amendment to its credit facility.

In addition, if required, the Company could also issue additional shares of stock and/or sell assets as needed to further fund operations.
