INVESTMENT OBJECTIVE

The Fund seeks to track the performance of an index composed of US Dollar denominated government bonds issued by the US Treasury.

Important Information: Capital at Risk. The value of investments and the income from them can fall as well as rise and are not guaranteed. Investors may not get back the amount originally invested.

Important Information:The value of your investment and the income from it will vary and your initial investment amount cannot be guaranteed. The Fund invests in fixed interest securities such as corporate or government bonds which pay a fixed or variable rate of interest. Therefore the value of these securities are sensitive to movements in interest rates; typically when interest rates rise there is a corresponding decline in the market value of bonds. Fixed income securities issued by governments can be affected by the perceived stability of the country concerned and proposed or actual credit rating downgrades.

Important Notice Regarding Change in Benchmark Index – Please note that with effect from Thursday, 26 May 2016, the benchmark index tracked by the iShares $ Treasury Bond 20+yr UCITS ETF (the “Fund”) (ticker symbol: IDTL) will change to the ICE U.S. Treasury 20+ Years Bond Index from the Barclays US 20+ year Treasury Bond Index and the Fund’s investment objective and policy will also change to reflect the new benchmark index. For further information please refer to the fund announcement in the 'Document Library’ section on iShares.com or contact your local iShares team.

Key Risks

Credit risk, changes to interest rates and/or issuer defaults will have a significant impact on the performance of fixed income securities. Potential or actual credit rating downgrades may increase the level of risk.Investment risk is concentrated in specific sectors, countries, currencies or companies. This means the Fund is more sensitive to any localised economic, market, political, sustainability-related or regulatory events.Counterparty Risk: The insolvency of any institutions providing services such as safekeeping of assets or acting as counterparty to derivatives or other instruments, may expose the Share Class to financial loss.Credit Risk: The issuer of a financial asset held within the Fund may not pay income or repay capital to the Fund when due.Liquidity Risk: Lower liquidity means there are insufficient buyers or sellers to allow the Fund to sell or buy investments readily.

Securities Lending

Securities lending is an established and well regulated activity in the investment management industry. It involves the transfer of securities (such as shares or bonds) from a Lender (in this case, the iShares fund) to a third-party (the Borrower). The Borrower will give the Lender collateral (the Borrower’s pledge) in the form of shares, bonds or cash, and will also pay the Lender a fee. This fee provides additional income for the fund and thus can help to reduce the total cost of ownership of an ETF.

 

At BlackRock, securities lending is a core investment management function with dedicated trading, research and technology capabilities. The lending programme is designed to deliver superior absolute returns to clients, whilst maintaining a low risk profile. Funds participating in securities lending retain 62.5% of the income, while BlackRock receives 37.5% of the income and covers all the operational costs resulting from securities lending transactions.

The above table summarises the lending data available for the fund.

The information in the Lending Summary table will not be displayed for the funds that have participated in securities lending for less than 12 months. The figures shown relate to past performance. Past performance is not a reliable indication of current or future results.
BlackRock’s policy is to disclose performance information quarterly subject to a one-month delay. This means that returns from 01/01/2019 to 31/12/2019 can be publicly disclosed from 01/02/2020.

Maximum on-loan figure may increase or decrease over time.

With securities lending there is a risk of loss should the borrower default before the securities are returned, and due to market movements, the value of collateral held has fallen and/or the value of the securities on loan has risen.
