Summary of Changes in the Fair Value of Level 3 Financial Assets

The following tables set forth a summary of changes in the fair value of our Level 3 financial assets and liabilities. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Transfers in and out of Level 3 occur at the beginning of each period. The securities which were transferred into Level 3 were due to decreased market observability of similar assets and/or changes to significant inputs, such as downgrades or price declines. Transfers out of Level 3 were due to increased market activity on comparable assets or observability of inputs.
