 eight years, we expect the majority to be redeemed or sold prior to maturity. These instruments often have call protection that requires an issuer to pay a premium if it redeems in the early years of an investment. The investment team regularly reviews investments and related market conditions in order to determine if an opportunity exists to realize returns on a particular investment. We believe the ability to utilize the entire resources of Blackstone Credit & Insurance, including the public market traders and research analysts, allows the Advisers to gain access to current market information where the opportunity may exist to sell positions into the market at attractive prices.
