At the start of year 3, 12000 new ordinary shares were issued at a premium of $1.5 per share in order to help raise further funds. given that ordinary shares have a nominal value of $1 for each share.

For this statement, does it means that I only need to put a credit entry of $18000 into share premium account or I also need to increase the ordinary share capital account by $12000? Then the total increase in cash account would be $30000?
