Short-Term Investments and Fair Value Measurement |
3. Short-Term Investments and Fair Value Measurement
The Companys investment policy is consistent with the definition of available-for-sale securities. The Company does not buy and hold securities principally for the purpose of selling them in the near future. The Companys policy is focused on the preservation of capital, liquidity and return. From time to time, the Company may sell certain securities but the objectives are generally not to generate profits on short-term differences in price. Short-term investments are therefore classified as available-for-sale securities and are reported at fair value as follows:
