The two leaders of Research In Motion Ltd. each plans to increase by $2.5 million the amount he will pay to settle with an institutional shareholder over the company's former option-granting policies. The BlackBerry maker said Friday it reached an agreement with the Ironworkers Ontario Pension Fund, which complained in court earlier this year about the company's investigation into its option-granting policies prior to 2002. The fund had sought an order forcing RIM to sue seven of its own directors to recover cash and shares they received for attending certain meetings. RIM says as part of the tentative settlement it will exclude independent directors from receiving stock options and hire an independent corporate governance expert to prepare a charter for the compensation committee. Jim Balsillie and Mike Lazaridis, who already announced they would repay the company up to $5 million each, now plan to pay $2.5 million more.
