FAIR VALUE MEASUREMENTS FAIR VALUE MEASUREMENTS

As of September 30, 2019, cash and cash equivalents include the Company’s investments in municipal and corporate debt securities, money market funds, and time deposits. The Company considers all highly liquid investments with original maturities of three months or less when purchased and have insignificant interest rate risk to be cash equivalents.  Debt securities classified as cash equivalents are required to be accounted for in accordance with the FASB Accounting Standards Codification (“ASC”) 320, Investments - Debt and Equity Securities. As such, the Company determined its investments in debt securities held at September 30, 2019 should be classified as available-for-sale and are carried at fair value with unrealized gains and losses reported in accumulated other comprehensive income in stockholders’ equity. The cost of debt securities is adjusted for amortization of premiums and discounts to maturity. This amortization is included in other income. Realized gains and losses, as well as interest income, are also included in other income. The fair values of securities are based on quoted market prices to the extent available or alternative pricing sources and models utilizing market observable inputs.

The carrying amounts of the Company’s financial instruments, including cash and accounts payable, approximate fair value because of their short maturities. The carrying amount of the noncurrent restricted cash approximates fair value since, absent the restrictions, the underlying assets would be included in cash and cash equivalents.
 
Accounting standards permit companies, at their option, to choose to measure many financial instruments and certain other items at fair value.  The Company has elected to not fair value existing eligible items.

Investments by significant category included in cash equivalents at the end of each period were as follows (in thousands):

1 FASB Topic 820, Fair Value Measurements, establishes a fair value hierarchy that requires the use of observable market data, when available, and prioritizes the inputs to valuation techniques used to measure fair value in the following categories:
Level 1: Quoted market prices in active markets for identical assets or liabilities.
Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data.
Level 3: Unobservable inputs that are not corroborated by market data.
