Fair Value Measurements

Fair Value Measurements

The Company uses various inputs in determining the fair value of its investments and measures these assets on a recurring basis.  Assets and liabilities recorded at fair value in the consolidated balance sheets are categorized by the level of objectivity associated with the inputs used to measure their fair value.  The following levels are directly related to the amount of subjectivity associated with the inputs to fair valuation of these assets and liabilities:

•Level 1 – quoted prices in active markets for identical assets, which include U.S. treasury securities

•Level 2 – other significant observable inputs (including quoted prices for similar investments, market corroborated inputs, etc.), which include corporate debt securities

•Level 3 – significant unobservable inputs

The inputs or methodology used for valuing securities are not necessarily an indication of the credit risk associated with investing in those securities.  The following tables provide the fair value measurements of applicable Company assets and liabilities that are measured at fair value on a recurring basis according to the fair value levels defined above as of December 31, 2019 and 2018.

The Company did not have any Level 3 assets or liabilities at December 31, 2019 or 2018. Transfers between levels are recognized at the actual date of circumstance that caused the transfer. There were no transfers between Level 1 and Level 2 during the periods presented.

The Company also has assets that under certain conditions are subject to measurement at fair value on a non-recurring basis.  These assets include goodwill associated with the acquisitions of Coelacanth Corporation in 2001 and Symphony Icon in 2010 and intangible assets associated with the acquisition of Symphony Icon in 2010.  For these assets, measurement at fair value in periods subsequent to their initial recognition is applicable if one or more is determined to be impaired.
