Taobiz explains Per Share Basis
To measure something on a per share basis, take the total quantity of whatever you are measuring and divide it by the number of outstanding shares in the company. For example if the earnings of a company is $2 million and there are 4 million shares, the earnings on a per share basis is $0.50 per share.
