Paul, Weiss, Rifkind, Wharton & Garrison advised Japan’s largest bank on what is expected to end up as the largest share issuance in the world this year, according to lawyers who worked on the deal.

The bank is Mitsubishi UFJ Financial Group, and it is seeking to raise as much as $12 billion by selling new shares starting sometime in the middle of this month, according to Bloomberg. If the bank hits that target, it will have raised about $28 billion in fresh capital via stock sales in the last 14 months, according to AFP.
