The primary focus of our investment strategy is to preserve capital and meet liquidity requirements. Our investment policy addresses the level of credit exposure by limiting the concentration in any one corporate issuer or sector and establishing a minimum allowable credit rating. To manage the risk exposure, we invest cash equivalents and marketable securities in a variety of fixed income securities, including government and investment-grade debt securities and money market funds. We place our cash primarily in checking and money market accounts with reputable financial institutions. Deposits held with these financial institutions may exceed the amount of insurance provided on such deposits, if any.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:36px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Concentrations of credit risk with respect to accounts receivable are primarily limited to certain customers to which we make substantial sales. Our customer base consists of a large number of geographically dispersed customers diversified across several industries. To reduce risk, we routinely assess the financial strength of our customers. Based on such assessments, we believe that our accounts receivable credit risk exposure is limited. No customer accounted for more than 10% of revenue for the </span><span style="font-family:inherit;font-size:10pt;">three and nine</span><span style="font-family:inherit;font-size:10pt;"> months ended </span><span style="font-family:inherit;font-size:10pt;">September 30, 2019</span><span style="font-family:inherit;font-size:10pt;"> and </span><span style="font-family:inherit;font-size:10pt;">2018</span><span style="font-family:inherit;font-size:10pt;">, or more than 10% of the total accounts receivable balance as of </span><span style="font-family:inherit;font-size:10pt;">September 30, 2019</span><span style="font-family:inherit;font-size:10pt;"> and </span><span style="font-family:inherit;font-size:10pt;">December 31, 2018</span><span style="font-family:inherit;font-size:10pt;">.</span></div>
