Investments [Abstract]  
Investments The Company follows the provisions of 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 about a company’s use of fair-value measurements, including the effect of such measurement on earnings. The cost of securities sold is based on the specific identification method.
The Company determines the fair value of its government 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 have remaining maturities of less than one year and are considered as Level 1 assets. These investments are carried at cost, which approximates fair value.

The Company will also periodically make technology investments in certain non-consolidated third-parties for ownership interests of less than 20%.  These investments do not have readily determinable fair values, and the Company has not identified any observable events that would cause adjustment of the valuation to date, and therefore these investments were held at cost at a total of $4.1 million and $3.85 million as of March 31, 2019 and December 31, 2018, respectively. These investments are classified within Long-Term Investments in the consolidated balance sheet. 
Assets or liabilities that have recurring fair value measurements are shown below as of March 31, 2019 and December 31, 2018:
