ISL Aberdeen Israel Fund (The) (delisted)

Investment objective

The fund’s goal is to track as closely as possible, before fees and expenses, the price and yield performance of the Barclays U.S. Treasury Inflation Protected Securities (TIPS) Index (Series L) ^SM .

Fund fees and expenses

This table describes the fees and expenses you may pay if you buy and hold shares of the fund. The table does not reflect brokerage commissions you may incur when buying or selling fund shares.

This example is intended to help you compare the cost of investing in the fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem all of your shares at the end of those time periods. The example also assumes that your investment has a 5% return each year and that the fund’s operating expenses remain the same. This example does not reflect any brokerage commissions you may incur when buying or selling fund shares. Your actual costs may be higher or lower.

The fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in the annual fund operating expenses or in the example, affect the fund’s performance. During the most recent fiscal year, the fund’s portfolio turnover rate was 22% of the average value of its portfolio.

Principal investment strategies

To pursue its goal, the fund generally invests in securities that are included in the Barclays U.S. Treasury Inflation Protected Securities (TIPS) Index (Series L) ¹ . The index includes all publicly-issued U.S. Treasury Inflation-Protected Securities (TIPS) that have at least one year remaining to maturity, are rated investment grade and have $250 million or more of outstanding face value. The TIPS in the index must be denominated in U.S. dollars and must be fixed-rate and non-convertible. The index is market capitalization weighted and the TIPS in the index are updated on the last business day of each month. As of March 28, 2013, there were 34 TIPS in the index. TIPS are publicly issued, dollar denominated U.S. Government securities issued by the U.S. Treasury that have principal and interest payments linked to an official inflation measure (as measured by the Consumer Price Index, or CPI) and their payments are supported by the full faith and credit of the United States.

It is the fund’s policy that under normal circumstances it will invest at least 90% of its net assets in securities included in the index. The fund will notify its shareholders at least 60 days before changing this policy. The fund will generally give the same weight to a given security as the index does. However, when the adviser believes it is in the best interest of the fund, such as to avoid purchasing odd-lots ( i.e. , purchasing less than the usual number of shares traded for a security), for tax considerations, or to address liquidity considerations with respect to a security, the adviser may cause the fund’s weighting of a security to be more or less than the index’s weighting of the security.

Under normal circumstances, the fund may invest up to 10% of its net assets in securities not included in its index. The principal types of these investments include those that the adviser believes will help the fund track the index, such as investments in (a) securities that are not represented in the index but the adviser anticipates will be added to the index; (b) high-quality liquid short-term investments, such as securities issued by the U.S. government, its agencies or instrumentalities, including obligations that are not guaranteed by the U.S. Treasury, and obligations that are issued by private issuers that are guaranteed as to principal or interest by the U.S. government, its agencies or instrumentalities, and (c) investment companies. The fund may also invest in cash, cash equivalents and money market funds, enter into repurchase agreements, and may lend its securities to minimize the difference in performance that naturally exists between an index fund and its corresponding index.

The adviser typically seeks to track the price and yield performance of the index by replicating the index. This means that the fund generally expects that it will hold the same securities as those included in the index. However, the adviser may use statistical sampling techniques if the adviser believes such use will best help the fund to track its index or is otherwise in the best interest of the fund. Statistical sampling techniques involve investing in a limited number of index securities that, when taken together, are expected to perform similarly to the index as a whole. These techniques are based on a variety of factors, including interest rate and yield curve risk, maturity exposures, and other risk factors and characteristics. The fund generally expects that its yield and maturity will be similar to those of the index. In addition, the fund generally expects that its weighted average effective duration will closely correspond to the weighted average effective duration of the index, which as of March 28, 2013 was 8.1 years.

The adviser seeks to achieve, over time, a correlation between the fund’s performance and that of its index, before fees and expenses, of 95% or better. However, there can be no guarantee that the fund will achieve a high degree of correlation with the index. A number of factors may affect the fund’s ability to achieve a high correlation with its index, including the degree to which the fund utilizes a sampling technique. The correlation between the performance of the fund and its index may also diverge due to transaction costs, asset valuations, timing variances, and differences between the fund’s portfolio and the index resulting from legal restrictions (such as diversification requirements) that apply to the fund but not to the index.

Principal risks

The fund is subject to risks, any of which could cause an investor to lose money. The fund’s principal risks include:

Market Risk.  Bond markets rise and fall daily. As with any investment whose performance is tied to these markets, the value of your investment in the fund will fluctuate, which means that you could lose money.

Investment Style Risk.  The fund is not actively managed. Therefore, the fund follows the securities included in the index during upturns as well as downturns. Because of its indexing strategy, the fund does not take steps to reduce market exposure or to lessen the effects of a declining market. In addition, because of the fund’s expenses, the fund’s performance is normally below that of the index.

Interest Rate Risk.  Interest rates will rise and fall over time. During periods when interest rates are low, the fund’s yield and total return also may be low. Changes in interest rates also may affect the fund’s share price: a sharp rise in interest rates could cause the fund’s share price to fall. The longer the fund’s duration, the more sensitive to interest rate movements its share price is likely to be.

Credit Risk.  The fund is subject to the risk that a decline in the credit quality of a portfolio investment could cause the fund to lose money or underperform. The fund could lose money if the issuer or guarantor of a portfolio investment fails to make timely principal or interest payments or otherwise honor its obligations.

Inflation Protected Security Risk.  The value of inflation protected securities, including TIPS, generally will fluctuate in response to changes in “real” interest rates, generally decreasing when real interest rates rise and increasing when real interest rates fall. Real interest rates represent nominal (or stated) interest rates reduced by the expected impact of inflation. In addition, interest payments on inflation-indexed securities will generally vary up or down along with the rate of inflation.

Sampling Index Tracking Risk.  To the extent the fund uses statistical sampling techniques, the fund will not fully replicate the index and may hold securities not included in the index. As a result, the fund will be subject to the risk that the adviser’s investment management strategy, the implementation of which is subject to a number of constraints, may not produce the intended results. If the fund uses a sampling approach, it may not track the return of the index as well as it would if the fund purchased all of the securities in the index.

Tracking Error Risk.  As an index fund, the fund seeks to track the performance of its benchmark index, although it may not be successful in doing so. The divergence between the performance of the fund and its benchmark index, positive or negative, is called “tracking error”. Tracking error can be caused by many factors and it may be significant. For example, the fund may not invest in certain securities in its benchmark index or match the securities’ weighting to the benchmark.

Liquidity Risk.  A particular investment may be difficult to purchase or sell. The fund may be unable to sell a security at an advantageous time or price.

Securities Lending Risk.  Securities lending involves the risk of loss of rights in the collateral or delay in recovery of the collateral if the borrower fails to return the security loaned or becomes insolvent.

Market Trading Risk.  Although fund shares are listed on national securities exchanges, there can be no assurance that an active trading market for fund shares will develop or be maintained. If an active market is not maintained, investors may find it difficult to buy or sell fund shares.

Shares of the Fund May Trade at Prices Other Than NAV.  Fund shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of the shares of the fund will approximate the fund’s net asset value (NAV), there may be times when the market price and the NAV vary significantly. You may pay more than NAV when you buy shares of the fund in the secondary market, and you may receive less than NAV when you sell those shares in the secondary market.

Lack of Governmental Insurance or Guarantee.  An investment in the fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.

Purchase and sale of fund shares

The fund issues and redeems shares at its NAV only in large blocks of shares, typically 50,000 shares or more (“Creation Units”). These transactions are usually in exchange for a basket of securities included in the index and/or an amount of cash. As a practical matter, only institutions or large investors purchase or redeem Creation Units. Except when aggregated in Creation Units, shares of the fund are not redeemable securities.

Individual shares of the fund trade on national securities exchanges and elsewhere during the trading day and can only be bought and sold at market prices throughout the trading day through a broker-dealer. Because fund shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (premium) or less than NAV (discount).

Tax information

Dividends and capital gains distributions received from the fund will generally be taxable as ordinary income or capital gains, unless you are investing through an IRA, 401(k) or other tax-advantaged account.
