Answer:
The principal office in State A.
Step-by-step explanation:
In this scenario, an investment adviser has its principal office in State A, as well as other offices in States B, C, and D. The net worth requirements of States C and D are more stringent than that required by State A and the net worth rules of State B are the most stringent of all. The investment adviser is required to maintain minimum net worth in accordance with the rules of the principal office in State A.
According to the Uniform Securities Act, an investment adviser is required by law to act in accordance with the provisions of the Uniform Securities Act as adopted in its principal office in State A. Also, States such as B, C, and D where its other offices are do not have the wherewithal to impose a more stringent net worth requirements on the investment adviser in State A.
Generally, the Uniform Securities Act is a model law created by the National Conference of Commissioners on Uniform State Laws (NCCUSL) to serve as a guide for state level laws and regulations. It primarily act as a complement to the Securities and Exchange Commission of the United States of America and to protect investors against state level securities fraud.
