- Commitments and Contingencies
 
Environmental
 
The Company is subject to various federal, state and local environmental laws and regulations that establish standards and requirements for the protection of the environment. The Company continues to monitor the status of these laws and regulations. However, the Company cannot predict the future impact of such standards and requirements on its business, which are subject to change and can have retroactive effectiveness.
 
Currently, the Company has
not
been fined, cited or notified of any environmental violations or liabilities that would have a material adverse effect upon its consolidated financial position, liquidity or capital resources. However, management does recognize that by the very nature of its business, material costs could be incurred in the near term to maintain compliance. The amount of such future expenditures is
not
determinable due to several factors, including the unknown magnitude of possible regulation or liabilities, the unknown timing and extent of the corrective actions which
may
be required, the determination of the Company
’s liability in proportion to other responsible parties and the extent to which such expenditures are recoverable from insurance or indemnification.
 
Litigation
 
The Company is, and from time to time
may
be, involved in claims and litigation arising in the ordinary course of business. Because there are inherent uncertainties in the ultimate outcome of such matters, it is presently
not
possible to determine the ultimate outcome of any pending or potential claims or litigation against the Company; however, management believes that the outcome of those matters that are presently known to the Company will
not
have a material adverse effect on the Company
’s consolidated financial position, results of operations or liquidity.

$34.0
million and including a contingent consideration liability valued at approximately
$14.4
million at the date of the acquisition. If the acquiree is able to achieve certain levels of EBITDA over a
three
-year period, the Company will be obligated to make future tiered payments of up to
$29.5
million. The contingent consideration liability is remeasured on a fair value basis each quarter until it is paid or expires. As of

the earn-out was estimated to have
