The following tables present the financial instruments that were measured at fair value on a recurring basis at September 30, 2019 and December 31, 2018 by level within the fair value hierarchy (in thousands):
We determine the fair value of Level 1 assets using quoted prices in active markets for identical assets. At December 31, 2018, we estimated the fair value of our investment in 10,000,000 common shares of CO2 Solutions using the market value of common shares as determined by trading on the TSX Venture Exchange, and we classified our investment in CO2 Solutions within the fair value hierarchy as Level 1 at December 31, 2018 using the quoted prices in an active market to determine their fair value.
In the quarter ended September 30, 2019, we reviewed our investment in the common shares of CO2 Solutions. Concurrent with CO2 Solutions' announcement to file under the Bankruptcy and Insolvency Act (Canada) and a suspension in trading of its equity securities, there was no observable market pricing available at September 30, 2019. We assessed the fair value of the investment and concluded to write down the investment to zero. We recognized a $0.4 million and a $0.5 million loss, respectively in the three and nine months ended September 30, 2019 in other expenses, net in the unaudited condensed consolidated statement of operations. For information see Note 6. "Cash Equivalents and Marketable Securities".
The entire disclosure of the fair value measurement of assets and liabilities, which includes financial instruments measured at fair value that are classified in shareholders' equity, which may be measured on a recurring or nonrecurring basis.
