As the Company announced on February 22, 2019, the Company’s Board of Directors determined that certain shareholders became Acquiring Persons, and a Trigger Event occurred under the Rights Agreement. As a result, 27,777,341 new common and 14,630,813 preferred shares of the Company were issued into a trust for the benefit of the holders of the valid and outstanding Rights. Releasing these shares from the trust is contingent on an outcome from the Company's legal proceeding in Antigua (Note 18). Without the effect of the implementation of the Rights Agreement and the newly issued common and preferred shares, basic weighted average number of common shares outstanding and diluted weighted average number of common shares outstanding would be 71,724,902 and 71,764,628, respectively. And the basic and diluted earnings per share for 2022 would be $ 1.59.
