NOTE

— COMMITMENTS AND CONTINGENCIES
 
 
Environmental Compliance and Remediation Liabilities
 
 
The Company's operations and products are subject to a variety of environmental laws and regulations in the jurisdictions in which the Company operates and sells products governing, among other things, air emissions, wastewater discharges, the use, handling and disposal of hazardous materials, soil and groundwater contamination, employee health and safety, and product content, performance and packaging. Certain environmental laws
may
impose the entire cost or a portion of the cost of investigating and cleaning up a contaminated site, regardless of fault, upon any
one
or more of a number of parties, including the current or previous owners or operators of the site. These environmental laws also impose liability on any person who arranges for the disposal or treatment of hazardous substances at a contaminated site. Third parties
may
also make claims against owners or operators of sites and users of disposal sites for personal injuries and property damage associated with releases of hazardous substances from those sites. 
 
Allowance for Doubtful Accounts
 
 
Based upon past experience and judgment, the Company establishes an allowance for doubtful accounts with respect to accounts receivable. The Company's standard allowance estimation methodology considers a number of factors that, based on its collections experience, the Company believes will have an impact on its credit risk and the collectability of its accounts receivable. These factors include individual customer circumstances, history with the Company, the length of the time period during which the account receivable has been past due and other relevant criteria. 
 
The Company monitors its collections and write-off experience to assess whether or
not
adjustments to its allowance estimates are necessary. Changes in trends in any of the factors that the Company believes
may
impact the collectability of its accounts receivable, as noted above, or modifications to its credit standards, collection practices and other related policies
may
impact the Company's allowance for doubtful accounts and its financial results. The activity in the accounts receivable allowance liability for the

Collateral
 
 
In select instances, the Company has pledged specific inventory and machinery and equipment assets to serve as collateral on related payable or financing obligations. 
 
Liquidated Damages
 
 
In certain customer contracts, the Company has agreed to pay liquidated damages in the event of qualifying delivery or production delays. These damages are typically limited to a specific percentage of the value of the product in question and/or are dependent on actual losses sustained by the customer. The Company does
not
believe that this potential exposure will have a material adverse effect on the Company's consolidated financial position or results of operations. There was
no
reserve for liquidated damages as of 
March 31, 2021
or
December 31, 2020.
