(Reuters) - The board of Goldman Sachs Group Inc said on Friday it is withholding a bonus worth at least $7 million from former chief executive Lloyd Blankfein until investigations into the bank's involvement in the 1MDB scandal are resolved. The bank also introduced a new forfeiture provision in its annual compensation plans for its top executives, including Chief Executive David Solomon and former head Blankfein, relating to the ongoing 1MDB proceedings. The company said in a regulatory filing its board can reduce pay packages of senior executives if it is later determined that the results of the ongoing probes would have impacted the their year-end compensation decisions.
