of future events. They include estimates of nat -
ural gas and oil reserves, expected production, 
assumptions regarding future natural gas and 
oil prices, planned drilling activity and capital 
expenditures, and future asset sales, as well as 
statements concerning anticipated cash flow and 
liquidity, business strategy and other plans and 
objectives for future operations. Although we 
believe the expectations and forecasts reflected 
in these and other forward-looking statements 
are reasonable, we can give no assurance they 
will prove to have been correct. They can be af -
fected by inaccurate assumptions or by known 
or unknown risks and uncertainties.
Factors that could cause actual results to differ 
materially from expected results are described 
under “Risk Factors” in Item 1A of our 2010 Annual 
Report on Form 10-K included in this report. We 
caution you not to place undue reliance on for -
ward-looking statements, and we undertake no 
obligation to update this information. We urge 
you to carefully review and consider the disclo -
sures made in this report and our other filings 
with the Securities and Exchange Commission 
(SEC) regarding the risks and factors that may 
affect our business.
The SEC requires natural gas and oil companies, in 
filings made with the SEC, to disclose proved re-  
serves and permits the optional disclosure of  
probable and possible reserves. While Chesapeake 
has elected not to report probable and possible  
reserves in its filings with the SEC, we have pro-  
vided estimates in this report of what we consider 
to be our “total resource base.” This term includes 
our estimated proved reserves as well as “risked 
and unrisked unproved resources,” which repre -
sent Chesapeake’s internal estimates of volumes of 
natural gas and oil that are not classified as proved 
reserves but are potentially recoverable through  
exploratory drilling or additional drilling or recovery 
techniques. Our estimates of unproved resources 
are not intended to correspond to probable and
