(*) | The negative amount included in the table above represents a gain, mainly as a consequence of the changes in the share prices of the Company.
In May 2013 the board of directors, upon the recommendation of the Compensation Committee, approved certain amendments to the 2009, 2010, 2011 and 2012 Long-Term Retention Plans (the Amended LTRPs), to give the Company (through the approval of the Compensation Committee) the option to pay the compensation due under the Amended LTRPs in cash, common stock or a combination thereof. The company has granted the right to any Amended LTRP participant to request settlement in cash. The Amended LTRPs have been considered to be a substantive liability and classified accordingly in the balance sheet.
