Earnings Per Common Share [Abstract] |
Earnings Per Common Share | 9. Earnings Per Common Share The Company calculates earnings per share using the two-class method in accordance with FASB ASC Topic 260. ﻿ The two-class method of computing basic earnings per share for each period reflects the cash dividends paid per share for each class of stock, plus the amount of allocated undistributed earnings per share computed using the participation percentage which reflects the dividend rights of each class of stock. Diluted earnings per share is calculated assuming the conversion of all shares of Class B Common Stock to shares of Class A Common Stock on a share-for-share basis. The tables below reconcile the numerators and denominators of basic and diluted earnings per share for current and prior periods. ﻿ ﻿
