[1] Gross realized losses from the sale of available-for-sale securities were immaterial.
[2] All marketable securities are classified as Level 2 securities. The fair value of Level 2 securities is estimated using actively quoted prices for similar instruments from brokers and observable inputs where available, including market transactions and third-party pricing services, or net asset values provided to investors. We do not currently have any Level 3 securities and there were no transfers between Level 2 or 3 during 2016 and 2015.
