In reply to:
So my question is: what CPI amounts are the latest batch of deliveries seeing? The percentage was 6.889 for the period 6/99 to 5/01.
Can’t answer your specific question (what are others seeing right now). But if you go to this page and then follow the link which says “All Urban Consumers (Current Series)” (under the “Most Requested Statistics” section) then select “US, All Items, 1982-84=100”, you’ll see a table which lists CPI per month.
It shows a value of 166.2 for June 99 and 177.7 for May 01. So that would be an increase of 6.919%, which is very close to the 6.889% you mentioned. In fact, it looks like you’re getting a slightly better deal than the numbers would indicate.
(Sorry for the long web directions above. The final result looks like the output of a cgi script so I can’t just link to the final table. My understanding is that the above CPI is the one most commonly refered to when people talk about “the CPI”, but I don’t know if that’s the index that Cirrus uses for calculations. Maybe the contract mentions a specific CPI index you’d want to look at instead of the generic one I mentioned above? If not you could always ask CD directly.)
