Revenue and Major Customers For the years ended December 31, 2015 and 2014, the Company’s largest customer accounted for approximately 31% and 22% of our revenues, respectively. The Company’s sludge processing agreement with Toho Water Authority, which was also its largest customer for the years 2011 through 2013, was not renewed at the beginning of 2014.

The Company’s failure to renew that agreement may have a material adverse effect on its business, financial conditions and results of operations. Additionally, economic considerations have made the supply of admixtures used in our processes more difficult to acquire due to coal-burning facilities operating less or not at all, primarily from the decrease in natural gas prices in the commercial marketplace. A substantial portion of the Company's revenue is derived from services provided under contracts and agreements with existing licensees. Some of these contracts, especially those contracts with large municipalities, provide for termination of the contract by the customer after giving relatively short notice (in some cases as little as ten days). In addition, some of these contracts contain liquidated damages clauses, which may or may not be enforceable in the event of early termination of the contracts. If one or more of these contracts are terminated prior to the expiration of its term, and the Company is not able to replace revenues from the terminated contract or receive liquidated damages pursuant to the terms of the contract, the lost revenue could have a material and adverse effect on its business and financial condition.
