In addition the Company has credit insurance in place through a third party insurer against defaults by certain other domestic and international customers, subject to policy limits. The Company generally does not require customers to provide collateral to support accounts receivable. The Company has recorded an allowance for doubtful accounts for those receivables that were determined not to be collectible.</font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Foreign cash balances at </font><font style="font-family:inherit;font-size:10pt;">December 31, 2018</font><font style="font-family:inherit;font-size:10pt;"> and </font><font style="font-family:inherit;font-size:10pt;">2017</font><font style="font-family:inherit;font-size:10pt;"> were </font><font style="font-family:inherit;font-size:10pt;">$5.2 million</font><font style="font-family:inherit;font-size:10pt;"> and </font><font style="font-family:inherit;font-size:10pt;">$0.1 million</font><font style="font-family:inherit;font-size:10pt;">, respectively.</font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div></div>

The Company evaluates estimates and assumptions on an ongoing basis using historical experience and other factors and adjusts those estimates and assumptions when facts and circumstances dictate. As future events and their effects cannot be determined with precision, actual results could differ from these estimates, and those differences could be material to the consolidated financial statements.</font></div></div>
