|
| Performance Narrative [Text Block] |
The following bar chart and table provide some indication
of the risks of investing in the Fund. The bar chart shows changes in the Fund's performance from year
to year for Class A shares, a class of the Fund that is invested in the same portfolio of securities
as Class P1 shares. The table shows the Fund's average annual returns for 1 year, 5 years, 10 years or
since inception, as applicable. The Fund's past performance is not necessarily an indication of how the
Fund will perform in the future. The performance for Class A shares is shown in lieu of Class P1 shares
because Class P1 has not yet operated for a full calendar year. Although Class A
shares
and Class P1 shares will be invested in the same portfolio of securities, Class P1 shares' performance
would have been lower than the performance shown for Class A shares because Class P1 shares have higher
expenses. You can obtain updated performance information at www.franklintempleton.com or by calling (800)
DIAL BEN/342-5236.
