Subsequent to September 30, 2019, the Company was notified that its largest frac sand client intends to discontinue purchases of frac sand under its existing contract with the Company.  Although the Company plans to idle all of its sand operations in the fourth quarter of 2019, and will evaluate alternatives for the sand business, it expects to continue to incur a significant amount of fixed cash costs associated with the rail cars and distribution center dedicated to this contract.
