Financial Regulatory Matters

Since 1984 Mr. Astarita has been the lawyer for advisors and brokerage firms in their registration and compliance matters, including the startup of new broker-dealers. From incorporation through shareholder and employment agreements, and throughout the registration process with the SEC and FINRA, Mr. Astarita has assisted dozens of firms in their navigation of the web of securities rules and regulations. When firms need to expand their operations and require FINRA approval, they have relied on him as their lawyer and has has guided those firms through the 1017 process, working closely with the firm’s in-house staff to obtain the necessary approvals.

As the regulatory environment has become more onerous and complex, Mr. Astarita began encouraging, and assisting, advisors and financial professionals to become independent financial advisors, either through agreements with some of the nation’s top independent brokerage firms, or through the creation of registered investment advisors or private investment partnerships. These alternate vehicles can vastly improve the business operations and overhead of a smaller financial firm, while at the same time maintaining the quality of research, customer service and investor protection of a large broker-dealer.

Regulatory Enforcement Matters

Mr. Astarita’s prime function as a securities lawyer is representation of financial professionals and investors in regulatory investigations, from the SEC, FINRA, state securities commissions, and the various commodity exchanges. His 30 years of experience in investigations and enforcement proceedings have enabled him to provide invaluable assistance to his clients, not only during the actual proceedings, but in the development of a comprehensive strategy and plan for dealing with actual, and potential, enforcement proceedings. At times there is no choice but to take an enforcement proceeding to hearing, and Mr. Astarita has the skill, experience and talent to effectively represent Respondents in such hearings, even going up against FINRA with unlimited resources.

Securities Employment Issues

Mr. Astarita extensive experience in securities employment issues, representing advisors and firms regarding the the negotiation of compensation packages and upfront loans, as well as severance agreements, promissory note settlements and restructuring, and non-compete waivers. Mr. Astarita has negotiated compensation agreements for individuals with every major Wall Street firm. The use of upfront bonuses, or employee forgivable loans as inducements and compensation for an advisor to change firms, has a series of issues, pitfalls and dangers, for the firm, and for the advisor. This experience, coupled with a continual monitoring of legal decision and trends enables him to effectively negotiate securities employment agreements for his clients.

Advisor Transition

As noted below, the transition from a brokerage firm to another firm, or to an investment advisory firm involves its own unique set of issues, and an entirely different regulatory environment, with different regulators, and different rules. As more and more professionals realize the advantages of using a fee-based model for the benefit of their clients, they realize the advantage of leaving the brokerage world and moving to the investment advisory side of the business. Mr. Astarita has been at the forefront of this move away from commission business and the overwhelming regulatory environment and has helped transition brokers to advisors for decades.

That same experience provides the foundation for the negotiation and resolution of employment separation agreements, waivers and modifications to non-compete agreements and promissory notes.

If the employment relationship does not go as planned, Mr. Astarita also provides representation and counsel in post-employment disputes, including severance agreements, re-negotiation of promissory notes and non-compete agreements, as well as ongoing counsel in post-termination investigations by FINRA and the SEC, as well as in litigation over the employer-employee relationship.
