The investment seeks to track the performance of a broad, market-weighted bond index. The fund employs an indexing investment approach designed to track the performance of the Barclays Capital U.S. Aggregate Float Adjusted Index. It invests by sampling the index, meaning that it holds a broadly diversified collection of securities that, in the aggregate, approximates the full index in terms of key risk factors and other characteristics. The fund invests at least 80% of assets in bonds held in the index. It maintains a dollar-weighted average maturity consistent with that of the index, ranging between 5 and 10 years.
