Is BSI a public or private company?

Could you elaborate on the nature of BSI's corporate status? Specifically, is BSI considered a publicly traded company, where its shares are available for purchase and sale on open markets, or is it a privately-held company, where ownership is restricted to a smaller group of investors and shareholders? This distinction is crucial in understanding the structure, operations, and financial transparency of BSI, as well as its potential for growth and expansion. Could you clarify this point for me?
