NH Investment & Securities said on Thursday it decided at an extraordinary board meeting to shift to a co-CEO management structure. The company plans to run key business divisions under a specialized, accountable management system. It expects the change to improve execution and speed up decision-making, while linking growth in client assets with investment banking capabilities to bolster its medium- to long-term growth base. The board also plans to put in place safeguards in stages.

Some decisions, including Hong Kong ELS fines and Samsung Securities approvals, remain delayed.
