BTO = Before the Market Open, ATC = After Market Closes

Summary: Of the ten (11) SH Letters released, three (3) were before the market open, one (1) was during the trading day, and seven (7) were after the market closed.

As of today, 1/23/09, it has been 32 days since the last Shareholder Letter. Given that there was recently an earnings release plus we had updates/Q&A on Webcast on 1/9 & 1/13/09, it would not surprise me if there is a longer time gap between SH Letter #11 and this next one. Still, over the course of 2008, RG averaged a Shareholder Letter every 31 days (excluding #4 as that was just a response to LQ v. Quanta), so we are in the typical timeframe when we see one.
