Earnings Per Share [Text Block] | Note 8 . Basic and Diluted Net Income ( Loss ) p er Share Basic net loss per share attributable to Avalon Holdings Corporation common shareholders is computed by dividing the net loss by the weighted average number of common shares outstanding. For the three and nine months ended September 30, 2019 and 2018, the weighted average number of common shares outstanding was 3,875,431 and 3,803,331 , respectively. Diluted net income (loss) per share attributable to Avalon Holdings Corporation common shareholders is computed by dividing net income (loss) by the weighted average number of common shares outstanding plus any weighted common equivalent shares determined to be outstanding during the period using the treasury method. The weighted common equivalent shares included in the calculation are related to stock options granted by Avalon where the weighted average market price of Avalon’s common stock for the period presented is greater than the option exercise price of the stock option. For the three months ended September 30, 2019 and 2018, the diluted weighted average number of shares outstanding was 3,892,948 and 4,048,683, respectively. For the nine months ended September 30, 2019, the diluted per share amount reported is equal to the basic per share amount because Avalon was in a net loss position and as a result, such dilution would be considered anti-dilutive. Assuming dilution, the weighted average number of common shares outstanding for the nine months ended September 30, 2019 was 3,909,706. For the nine months ended September 30, 2018, the diluted weighted average number of shares outstanding was 3,895,129.
