(a) | 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 analysis, third-party appraisals or industry multiples and public comparables. There has not been any significant change in the fair value of the redeemable preferred stock since our assessment as of December 31, 2016.
