[1] The fair value of Level 2 securities is estimated primarily using actively quoted prices for similar instruments from brokers and observable inputs, including market transactions and third-party pricing services. We do not currently have any Level 3 securities, and there were no transfers between Level 2 or 3 during the first half of 2015 and 2014.
