If your company has outside shareholders and investors, you should delegate someone to handle investor relations. This person should be fluent in the language of finance, and have good communication and marketing skills. He or she must also keep current on all securities laws and regulations that apply to your company, and knowledgeable in the areas of compliance, reporting and fiduciary duty.
Most securities commissions provide information and seminars, and there are national organizations in many countries which hold training courses and ongoing informational sessions for investor relations officers.
