Management believes that its most significant estimates and assumptions have been based on reasonable and supportable assumptions and the resulting estimates are reasonable for use in the preparation of the Consolidated Financial Statements. The Company’s significant estimates include estimates associated with revenue recognition on construction contracts, costs incurred through each balance sheet date, impairment of goodwill, intangibles, property and equipment, fair valuation in business combinations, insurance reserves, income tax valuation allowances, and contingencies. If the underlying estimates and assumptions upon which the Consolidated Financial Statements are based change in the future, actual amounts may differ from those included in the accompanying Consolidated Financial Statements.</font></div> </div><table border="0" style="width:100%; table-layout:fixed;" cellspacing="0" cellpadding="0"><tr><td></td></tr></table>

The Subordinated Loan holders could have further elected to be paid entirely in Limbach common stock or to receive a cash payment equal to the deferred interest portion of the loan being converted, plus shares of Limbach common stock determined by a formula equal to the Conversion Shares, minus the Liquidation Shares (defined as the portion of the deferred interest portion of the loan being converted, divided by the five-day weighted trading average of a share of Limbach common stock for the five business days preceding the trigger date). Upon a Conversion Event, the subordinated debt holders had registration rights with respect to such shares, including one demand registration right and usual and customary “piggy-back” registration rights, pursuant to a registration rights agreement.
