The Company adheres to its investment policy when placing investments. The investment policy has established guidelines to limit the Company’s exposure to credit risk by placing investments with high credit quality financial institutions, diversifying its investment portfolio, limiting investments in any one issuer or pooled fund and placing investments with maturities that maintain safety and liquidity. Deposits with these financial institutions may exceed the amount of insurance provided; however, these deposits typically are redeemable upon demand and, therefore, the Company believes that the financial risks associated with these financial instruments are minimal.</span></div><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:20px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company generally does not require collateral on its accounts receivable. The Company estimates its allowances for doubtful accounts based on historical collection trends, the age of outstanding receivables and existing economic conditions. If events or changes in circumstances indicate that specific receivable balances may be impaired, further consideration is given to the collectability of those balances and the allowance is adjusted accordingly. Past-due account balances are written off when the Company’s internal collection efforts have been unsuccessful in collecting the amounts due. The Company does not have off-balance sheet credit exposure related to its customers and to date, the Company has not experienced significant credit-related losses.</span></div>
