General and administrative expenses decreased $0.9 million to $26.7 million for the year ended December 31, 2020, down from $27.6 million in the prior year period. The decrease was primarily the result of $1.9 million of expense reductions due to COVID-19, offset by a $3.2 million increase in professional fees and a $0.6 million provision for expected credit losses against our accounts receivable balances. During fiscal 2019, we incurred $2.6 million of expenses related to the listing of our common shares on the Nasdaq Global Select Market (“Nasdaq”), which did not reoccur in 2020.
Operations support expenses decreased $1.7 million to $9.4 million for the year ended December 31, 2020, down from $11.0 million for the prior year period. The decrease was the result of lower consulting costs and a decrease in travel, meals and entertainment costs in 2020 due to COVID-19 restrictions. These decreases were partially offset by an increase in personnel costs due to increased headcount. In 2019, we incurred $1.1 million of consulting costs to assist with the rectification of a tile warping issue.
Technology and development expenses increased by $0.3 million to $8.1 million for the year ended December 31, 2020, compared to $7.8 million for the prior year period, due to increased professional fees related to patents of our technology.
Net loss for the year ended December 31, 2020 was $11.3 million, an increase in losses of $6.9 million from net loss of $4.4 million for the year ended December 31, 2019. The increase in net loss is attributable to the above noted reduction in gross profit and a $1.1 million increase in income tax expense, partially offset by a $14.3 million reduction in operating costs, a $0.7 million decrease in foreign exchange losses, and government subsidies of $12.7 million.
Adjusted EBITDA and Adjusted EBITDA Margin for the year ended December 31, 2020 was a $7.2 million loss and (4.2%), respectively, a decline of $25.4 million or 140% from $18.2 million and 7.4% for the year ended December 31, 2019 for the above noted reasons. This reflects a $34.5 million decrease in Adjusted Gross Profit, partially offset by reduced commissions on lower revenues and decreased spending on travel, meals and entertainment expenses, including tradeshows due to COVID-19 related reductions.
