The Fund employs a passive management or indexing investment approach, through physical acquisition of securities, designed to track the performance of the index. The Fund will invest in a portfolio of fixed income securities with greater than 1 year maturity (for example UK Gilts, debt guaranteed by national government and its agencies) that so far as possible and practicable consists of the component securities of the index. The average duration of such fixed income securities is medium term, whilst the range for individual fixed income securities may be between 1 and 50 years.
