How does an individual transfer cash assets and ETF funds held in US bank and US broker to a company?

[DavidS]

Let's say that a non-US individual has cash assets held in US bank and has ETF funds held in US broker.

This individual registers offshore companies (not sure of jurisdiction yet, any advice?) and opens bank accounts and broker accounts for these offshore companies.

How would one transfer assets from individual to the company (stocks and cash)?
