Lead Bank

It can be a type of community bank that acts at the lender for coordination of the role of various credit institutions.

It is the institution that can persuade other financial organizations to contribute to a kind of massive loan for projects such as railway upgrade or investing in global markets.  

Such a group of global investment banks (and commodities brokerage firm) can determine how to sell a percentage of the offerings where the underwriter collects and manages the process of sales of the securities.

His team creates the prospectus about the company, determines how to buy sell online, and other relevant documents.
When a company decides to issue securities, it hires a lead underwriter to manage the process who has the responsibility to set the offering price and allocate shares to the syndicate members.

The reputation of the bank can have a strong impact on the success of the offering; therefore companies try to hire most reputed national organizations with an extensive brokerage network and in-house research abilities to handle the process of stock offerings.
