What is a SPAC?
A special purpose acquisition company (SPAC) is a company with no commercial operations, typically formed by individual(s) who are looking for a profitable company to acquire, and who generally supply the starting capital for the company.
After completion of the registration statement with the U.S. Security Exchange Commission (SEC), the new SPAC company uses the same audit process as they did during registration to become a publicly traded company, referred to as “going public,” with an initial public offering (IPO). After going public, those who wish to become investors in the venture are able to buy shares in the SPAC.
The money raised in an IPO is placed in an interest-bearing trust account. After the SPAC raises the desired amount of funds, they generally have 18-24 months to identify a target company to acquire and complete the process of acquisition.
If a target is found and acquired within the time frame, the investors then profit from their percentage of purchased shares in the newly acquired company. If a target is not found within the given time frame, the SPAC is liquidated, and the funds are returned to the investors (less any pre-determined fees).
