Investments Investments
The Company follows the provisions of Accounting Standards Codification ("ASC") 820, Fair Value Measurements and Disclosures, for its financial assets and liabilities, and for its non-financial assets and liabilities subject to fair value measurements. ASC 820 provides a framework for measuring the fair value of assets and liabilities. This framework is intended to provide increased consistency in how fair value determinations are made under various existing accounting standards that permit, or in some cases, require estimates of fair-market value. This standard also expanded financial statement disclosure requirements with respect to a company’s use of fair-value measurements, including the effect of such measurements on earnings. The cost of securities sold is based on the specific identification method.
The Company determines the fair value of its government securities, asset-backed securities, municipal bonds, and corporate bonds by utilizing monthly valuation statements that are provided by its broker. The broker determines the investment valuation by utilizing the bid price in the market and also refers to third party sources to validate valuations, and as such are classified as Level 2 assets.
The Company's certificates of deposit are classified as available for sale and are considered as Level 1 assets. These investments are carried at cost, which approximates fair value.

The Company also periodically makes technology investments in certain non-consolidated third parties. These equity investments are accounted for in accordance with ASC 323, Investments - Equity Method and Joint Ventures. The Company's share of the earnings or losses of non-controlled affiliates, over which the Company exercises significant influence (generally a 20% to 50% ownership interest), is included in the consolidated operating results using the equity method of accounting. The Company has also made technology investments in certain non-consolidated affiliates for common share ownership interests of less than 20% (where the Company does not have the ability to exercise significant influence). These equity investments are accounted for in accordance with ASC 321, Investments - Equity Securities. For these equity investments that do not have readily determinable fair values, and where the Company has not identified any observable events that would cause adjustment of the valuation to date, the equity investments are held at cost.

Such technology investments totaled approximately $94.0 million and $69.5 million as of June 30, 2023 and December 31, 2022, respectively. On March 9, 2023, the Company purchased a 15% equity investment in Adasky, LTD. for $21.5 million. Adasky is an Israeli-based leading developer and manufacturer of intelligent thermal sensing technologies. $2.2 million and $3.8 million of these technology investments are classified within Short-Term Investments in the condensed consolidated balance sheets as of June 30, 2023 and December 31, 2022, respectively. $91.8 million and $65.7 million of these investments are classified within Long-Term Investments in the condensed consolidated balance sheets as of June 30, 2023 and December 31, 2022, respectively.  
Assets or liabilities that have recurring fair value measurements are shown below as of June 30, 2023 and December 31, 2022:

Effective January 1, 2020, the Company adopted ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments. The guidance modifies the impairment model for available-for-sale debt securities and provides a simplified accounting model for purchased financial assets with credit deterioration since their origination. The Company utilized the guidance provided by ASC 326 to determine whether any of the available-for-sale debt securities held by the Company were impaired. No investments were considered to be impaired during the periods presented. The Company has the intention and current ability to hold its debt investments until any amortized cost basis has been recovered.
