TOKYO -(Dow Jones)- Mitsubishi UFJ Morgan Stanley Securities Co. will raise Y45 billion through the issuance of news shares expected to be completed Nov. 24, according to a regulatory filing submitted Monday. Of the total, Mitsubishi UFJ Securities Holdings Co., a unit of Mitsubishi UFJ Financial Group Inc. (8306.TO), will buy Y20 billion of the shares. Like other brokers, Mitsubishi UFJ Morgan Stanley Securities, a joint venture brokerage with Morgan Stanley, has struggled in light of the market turmoil sparked by Europe's debt crisis, posting net losses of Y3.16 billion in the July-September quarter. The capital injection the bank plans to give the brokerage is apparently intended to help the company get back on its feet. -By Kana Inagaki, Dow Jones Newswires; 813-6269-2795; kana.inagaki@dowjones.com
