Goldman Sachs Group Inc.'s annual payout may fall 28 percent to $4.9 billion, according to the consensus. The New York-based investment bank may increase the annual dividend to $1.47 a share from the current $1.40, and repurchase $4.17 billion in shares, or about 7 percent of the 495 million shares outstanding. Total dividends and buybacks probably will be down from last year when the company had more shares outstanding.
