History of Changes to the IFA Indexes and Portfolios

IFA Announces Changes to its Index Portfolios for New Investors

As of January 1, 2008, DFA has enacted a “soft close” of two of its funds. This means that existing investors will be able to add to their current positions, but new investors will not be able to purchase positions in these funds. Therefore, IFA will no longer be using the DFA U.S. Micro Cap Portfolio or the DFA U.S. Small Cap Value Portfolio for new investors (or for new non-taxable accounts added by existing investors).

In place of Micro Cap, the DFA U.S. Small Cap Portfolio (DFSTX) will be used. DFSTX includes holdings in micro cap companies. In place of Small Cap Value, the DFA U.S. Targeted Value Portfolio (DFFVX) will be used. DFFVX has a slightly larger range of acceptable company sizes than Small Value. These changes apply to non-taxable accounts only. For taxable accounts, no changes are being made. It is anticipated that the future performance of these new portfolios will be quite close to the “classic” IFA portfolios.

Since the returns on the website are primarily geared to prospective investors, the historical returns shown will be changed to reflect these substitutions, as time permits.

Beginning on June 3, 2008, IFA will use the DFA Global Real Estate fund in place of the U.S. Real Estate fund for new clients. Historical returns for the IFA Real Estate Index will not be changed.


1. November 2002:
Due to the high similarity of the 1999 versions of index portfolios 95 and 100 to index portfolio 90, the 95 and 100 portfolios were moderately modified in November 2002 to have higher exposure to small and value equities throughout the world. According to the extensive research of Eugene Fama, Kenneth French and Jim Davis, utilizing data from the Center for Research of Security Prices (CRSP) over a 68 year period from July 1929 to June 1997, this change has higher risk and return expectations than the previous versions of 95 and 100. (see Characteristics, Covariances, and Average Returns: 1929-1997)

2. January 2004: IFA changed the computer program setting to calculate annual rebalancing on the various indexes in the index portfolios in January 2004. Previous to that they were rebalanced monthly. Annual rebalancing is closer to the actual rebalancing of client accounts, therefore it was adopted as the new method in January 2005.

3. June 2006: The historical monthly returns of the fifteen IFA indexes and the twenty IFA index portfolios were reconstructed in June of 2006 to address the following issues:

  • I.) The availability of new and better sources of data for historical returns.
  • II.) The correction of errors in the prior data.
  • III.) Changes to the substitution of U.S. index data for international indexes in years prior to the existence of international data.

The overall impact of these changes to the returns is small. To illustrate, the 79-year average annualized returns for Portfolios 5, 50, and 100 changed as follows:

       Average Annualized Return from Jan. 1927 to Dec. 2005

 
Portfolio 5 
Portfolio 50    
Portfolio 100
Old Return 
5.66%
9.65%
12.58%
New Return

4. January 2008: The historical monthly returns of the fifteen IFA indexes and the twenty IFA index portfolios were reconstructed in January of 2008 to address the following issues:

  • I.) The availability of new and better sources of data for historical returns.
  • II.) The substitution of U.S. Small Cap for U.S. Micro Cap.
  • III.) The substitution of U.S. Targeted Value for U.S. Small Value.
