Cash Equivalents And Short Term Investments [Abstract] |
Cash Equivalents and Short Term Investments | Cash Equivalents and Short Term Investments Cash Equivalents Cash equivalents consist of interest bearing deposits with our bank totaling $9,204,919 (December 31, 2016 – $10,679,992). The current annual interest rate earned on these deposits is 1.38% (December 31, 2016 – 0.96%). Short-Term Investments Short-term investments consisted of guaranteed investment certificates which are liquid investments that are readily convertible to known amounts of cash and are subject to an insignificant risk of changes in value. The objectives for holding short-term investments were to invest our excess cash resources in investment vehicles that provided a better rate of return compared to our interest bearing bank account with limited risk to the principal invested. We intended to match the maturities of these short-term investments with the cash requirements of the Company’s activities and treat these as held-to-maturity short-term investments.
