3. CASH AND CASH EQUIVALENTS

 

Cash and cash equivalents amounted to $2,521,050 and $3,798,811 as of December 31, 2018 and 2017, respectively. Short-term investments were liquidated during 2017 to partially finance the investment in our Nisin production facility. The cost of securities sold is based on the specific identification method. Realized gains and losses and declines in value, judged to be other than temporary, are included in investment income. We are required by bank debt covenant to maintain at least $2,000,000 of otherwise unrestricted cash, cash equivalents and short-term investments.
