Fair Value Measurements Using:	​	​	​	​	​	​
Quoted prices in active markets (Level 1):	​	​	​	​	​	​
Cash equivalents and money market funds		$	419		$	530
Significant other observable inputs (Level 2):	​	​	​	​	​	​

Total Assets		$	925	​	$	969

(a) Our available-for-sale securities primarily relate to debt securities with maturities over the next nine years.

(b) When available, Level 3 investments have been measured based on third-party investors’ recent or pending transactions in these securities, which are considered the best evidence of fair value. When this evidence is not available, we use other valuation techniques as appropriate and available. These valuation methodologies may include transactions in similar instruments, discounted cash flow techniques, third-party appraisals or industry multiples and public company comparable transactions.

Tabular disclosure of assets and liabilities, including [financial] instruments measured at fair value that are classified in stockholders' equity, if any, that are measured at fair value on a recurring basis. The disclosures contemplated herein include the fair value measurements at the reporting date by the level within the fair value hierarchy in which the fair value measurements in their entirety fall, segregating fair value measurements using quoted prices in active markets for identical assets (Level 1), significant other observable inputs (Level 2), and significant unobservable inputs (Level 3).
