How is "Historic P/E Excluding Extraordinary Items, Avg. Diluted Shares Outstanding-5 Year Average" calculated?

Also, how is "P/E excluding extordinary items-5 Year Average" different than:
"Historic P/E Excluding Extraordinary Items, Avg. Basic Shares Outstanding-5 Year Average"
"Historic P/E Excluding Extraordinary Items, Avg. Diluted Shares Outstanding-5 Year Average"
Is it the same as one of them?
Thanks.
