Share-based Compensation Arrangement by Share-based Payment Award [Line Items]
Description of shares issued in respect of any 'full-value award'	For these purposes, shares subject to awards granted under the 2000 Plan that are "full-value awards" (as described below) will be taken into account based on the full-value award ratio described below. Shares issued in respect of any "full-value award" granted under the 2011 Plan will be counted against the share limit described in the preceding paragraph as 1.50 shares for every one share actually issued in connection with the award. For this purpose, a "full-value award" means any award granted under the plan other than a stock option or stock appreciation right.
