Fixed Price Contract

The Company’s multi-year contracts with its commercial customers contain fixed prices for product. These contracts expire through 2019 and expose the Company to the potential risks associated with rising material costs during that same period. Revenue reported during interim periods were recorded based on the facts and circumstances at the time and any differences noted when the final revenue is determined is considered to be a change in estimate for the period.

Legal proceedings

The Company is involved in various claims and legal proceedings arising from the normal course of business. While the ultimate liability, if any, from these proceedings is presently indeterminable, in the opinion of management, these matters should not have a material adverse effect on the Company’s consolidated financial statements.
