The results of operations for the three and nine months ended September 30, 2014 are not indicative of the results that may be expected for the year ending December 31, 2014 because, among other reasons, such results can vary depending on the timing of progress achieved and changes in estimated profitability of projects being reported. The Company considers events or transactions that occur after the balance sheet date but before the financial statements are issued to provide additional evidence relative to certain estimates or to identify matters that require additional disclosures.
