In the primary market, there are four key players: corporations, institutions, investment banks, and public accounting firms. Institutions invest capital in corporations that seek to expand and grow their businesses, while corporations issue debt or equity to institutions in return for their capital investment. Investment banks are hired to match institutions and corporations based on their risk profile and investment style. Finally, public accounting firms are responsible for the preparation, review, and auditing of financial statements, tax work, consulting on accounting systems, M&A, and capital raising. Hence, public accounting firms in the primary market not only assist corporations to raise capital but also help prepare, review, and audit financial statements to ensure a fair representation of their financial performance.
