From 2002 to 2004, the annual values for SAIFI trended downward to 20%<br />
below (better than) the benchmark. The slight increase in 2005 is insignificant,<br />
since SAIFI is still 17% below the benchmark. The rolling 12-month averages for<br />
all four quarters in 2005 remained well below the benchmark. For the 12-month<br />
period ending March 2006, SAIFI was slightly higher at 1.17.<br />
