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  possible reserves, as defined by SEC regulations,  and are by their nature more speculative than  estimates of proved reserves and accordingly are  subject to substantially greater risk of being ac- tually realized by the company. 2011  High  Low  Last First Quarter  $ 35.95  $ 25.93  $ 33.52 2010  High  Low  Last Fourth Quarter $ 26.43  $ 20.97  $ 25.91 Third Quarter 23.00  19.68   22.65 Second Quarter  25.55  19.62  20.95 First Quarter 29.22  22.10  23.64 2009  High  Low  Last Fourth Quarter $ 30.00  $ 22.06  $ 25.88 Third Quarter 29.49  16.92   28.40 Second Quarter  24.66  16.43  19.83 First Quarter 20.13  13.27  17.06 2008  High  Low  Last Fourth Quarter $ 35.46  $ 9.84  $ 16.17 Third Quarter 74.00  31.15   35.86 Second Quarter  68.10  45.25  65.96 First Quarter 49.87  34.42  46.15 WWW.CHK.COM
