Shares in Dow Jones fell on Monday to significantly below the $60-per-share offer from Rupert Murdoch’s News Corp amid uncertainty about whether enough members of the company’s controlling Bancroft family would back a sale.

Hemenway and Barnes, Boston-based trustees for the Bancroft family, told the family to submit their votes on the News Corp offer by 5pm Eastern Time on Monday, but it was unclear when the results would be announced.
