"Our Index continues to show a welcome strengthening of the California
economy, with seven of the nine components of our Index contributing
positively in August," said Dana Johnson, Chief Economist at Comerica Bank.
"The key missing ingredient to a sustained and healthy rebound continues to be
job growth. It is the only component of our index that has not contributed
positively since it bottomed five months ago in March."

The California Economic Activity Index equally weights nine,
seasonally-adjusted coincident indicators of real economic activity. These
indicators reflect activity in the manufacturing, tourism, travel and trade
sectors, as well as job growth and consumer outlays. The Index levels
represent a 3-month moving average, used to smooth monthly volatility. The
Index is benchmarked so that 2008 equals 100. A complete historical series
dating to 1997 is available upon request.
