Stock Split, Description | On July 22, 2011, the Board of Directors authorized a three-for-two stock split in the form of a stock dividend. The additional shares were distributed on August 24, 2011 to shareholders of record on August 10, 2011. |  |  |  |  |  |  |  |
[1] | Upon maturity of the Senior Exchangeable Notes (the "Notes"), Rayonier will not issue additional shares for the Notes due to the offsetting exchangeable note hedges (the "hedges"). However, accounting guidance under Accounting Standards Codification 260, Earnings Per Share requires the assumed conversion of the Notes to be included in dilutive shares, while the assumed conversion of the hedges are excluded since they are anti-dilutive. For additional information on the potential dilutive impact of the Senior Exchangeable Notes, warrants and exchangeable note hedges, see Note 11 - Debt in the 2010 Annual Report on Form 10-K.
