  • Duration band constraint:  to limit the index’s maximum or minimum weight to +/-3% versus the eligible universe, within several duration-buckets

Northern Trust is the owner of any trademarks, service marks and copyrights related to its respective indexes. Index Data is provided by Thomson Reuters, Interactive Data Corporation, and Northern Trust Index Services. Performance returns displayed on this page are shown as Total Return or Net Total Return depending on whether the index universe is inclusive of US or non-US securities. Northern Trust's publication of the Northern Trust Indexes in no way suggests or implies an opinion by Northern Trust as to the attractiveness or appropriateness of investments in any or all securities upon which the Northern Trust Indexes are based.

All information presented prior to the index inception date is back-tested. Backtested performance is not actual performance, but instead hypothetical. The backtest represents a reasonable attempt to replicate how the index would have performed at each point in history. Returns produced by backtested results should be considered approximate to what the index would have returned had it actually been live, while trading/transaction costs, data availability, etc are not factored into the return. Past performance of the Indices is not an indication of future results. Prospective application of the methodology used to construct the Indices may not result in performance similar to the back-test returns shown. The backtest period does not necessarily correspond to the entire available history of the Index. For more details about the indices, including the manner in which they are rebalanced, the timing of such rebalancing, criteria for additions and deletions, as well as all index calculations, please refer to the methodology documents.

Another limitation of backtested hypothetical information is that generally the backtested calculation is prepared with the benefit of hindsight. Backtested data reflect the application of the index methodology and selection of index constituents in hindsight. No hypothetical record can completely account for the impact of financial risk in actual trading. For example, there are numerous factors related to the equities (or fixed income, or commodities) markets in general which cannot be, and have not been accounted for in the preparation of the index information set forth, all of which can affect actual performance.

Indexes and/or benchmarks are unmanaged and cannot be invested in directly. Returns represent past performance, are not a guarantee of future performance, and are not indicative of any specific investment.
