Fair Value Disclosures [Abstract]  
FAIR VALUE MEASUREMENTS FAIR VALUE MEASUREMENTS
Assets Measured and Recorded at Fair Value on a Non-Recurring Basis
Equity method investments, and certain non-financial assets, such as intangible assets and property, plant and equipment, are remeasured at fair value only if an impairment or observable price adjustment is recognized in the current period.
Financial Instruments Not Recorded at Fair Value on a Recurring Basis
Financial instruments not recorded at fair value on a recurring basis include vendor financing arrangements. The carrying value of the vendor financing agreements were $1.9 million as of September 30, 2022 and $1.1 million as of December 31, 2021, respectively. The Company’s vendor financing arrangements are classified within Level 2 because these borrowings are not actively traded and have a variable interest rate structure based upon market rates currently available to the Company for debt with similar terms and maturities. The estimated fair values of these financial instruments approximate their carrying values.

Money market funds are highly liquid investments and are actively traded. The fair value is based on quoted prices for identical assets in active markets and therefore classified as Level 1 of the fair value hierarchy.

The Company’s other investments are considered Level 2 financial instruments as their fair values are determined using inputs that are directly or indirectly observable in active or less active markets. There were no transfers between levels during the three and nine months ended September 30, 2022.
The Company did not have any investments in available-for-sale securities as of December 31, 2021.
