Lloyds Banking Group has announced it will sell shares at 37p in the UK's biggest rights issue.
A rights issue is when a company issues new shares and sells them to existing shareholders at a discount to the listed share price.
The shares are being sold at a discount of 59.5% to Monday's closing price.
The bank hopes to raise £13.5bn from the share sale to avoid taking part in the government's banking insurance scheme - the Asset Protection Scheme.
Shares in Lloyds, which is 43%-owned by the government, ended Tuesday trading up 2.6%.
The 37p price is a discount of 38.6% on the so-called theoretical ex-rights price - which takes into effect the number of new shares on the market.
A total of 36.5 billion new shares will be issued - that amounts to 1.34 new shares for every one already in existence.
The sheer number of new shares has raised fears that the value of each one will be diluted.
Robert Talbot from Royal London Asset Management said the company's fate is ultimately linked to the performance of the UK economy.
"I think it puts them into a much stronger capital position to be able to withstand whatever lies ahead. The crucial question facing the bank over the next two to three years is what happens to the UK economy," he said.
Lloyds has 2.8 million shareholders and Britain's largest number of private investors. Shareholders will meet on Thursday in Birmingham to approve the plan.
It will cost the average shareholder £336.67 to take part in the share sale. They do not have to buy the new shares but if they do not they will see the stock that they already own diluted in value.
The rights issue is part of Lloyds' wider plans to raise about £22.5bn overall.
It said on Monday that it had secured over £8.8bn from a bond issue.
