Italy's third-largest bank announced late on Thursday it would price new shares at 1.17 euros each, or a 38.9 percent discount to the price of the stock when excluding subscription rights.

It will offer 10 new shares for every Monte Paschi share already held.

Under the terms, shareholders who do not buy into the cash call would see their stake diluted by around 90 percent, according to Reuters calculations.
