Management estimates Consolidated Adjusted EBITDA would have been us$ 3.4 million higher had table game hold at these properties been at normal levels.
Loss from continuing operations was us$ 42 million versus income of us$ 17.7 million in the prior year period, principally as a result of higher depreciation and interest expense from the opening of L'Auberge Baton Rouge and us$ .6 million of one-time items.
The Company recorded us$ 40.6 million of charges in the 2012 fourth quarter, including: a non-cash write down of approximately us$ 25 million related to its ACDL investment (included in Loss on equity method investment), a us$10.2 million charge related to its St. Louis redevelopment agreement that reflects the aggregate impact of cash and land donation commitments made by the Company for various projects in St. Louis, and accelerated depreciation expense of us$ 4.7 million stemming from the demolition of the grandstand and related facilities at River Downs.
Adjusted income per share, which normalizes for the effect of one-time items, was us$0.03 in the 2012 fourth quarter versus us$ 0.25 in the prior year period and a record us$0.99 in the full year 2012 versus us$ 0.69 in the prior year period.

Consolidated Adjusted EBITDA increased us$1.1 million or 1.7% year over year to us$63.3 million. Consolidated Adjusted EBITDA margin decreased 158 basis points year over year to 21.0%, principally due to L'Auberge Baton Rouge still being in its operational ramp up period. On a same store basis, Consolidated Adjusted EBITDA margin was essentially unchanged year over year at 22.5%.
Operating income was us$ 11.9 million in the 2012 fourth quarter versus us$ 37.1 million in the prior year period. Loss from continuing operations was us$ 42 million in the 2012 fourth quarter versus income of us$17.7 million in the prior year period. The year over year decrease in both Operating income and Income from continuing operations was driven principally by increased depreciation and amortization associated with the opening of L'Auberge Baton Rouge, accelerated River Downs depreciation, and the St. Louis redevelopment agreement charge. Income from continuing operations was further impacted by the non-cash write-down of the Company's investment in ACDL and by increased interest expense from the financing completed in March 2012 and due to the opening of L'Auberge Baton Rouge, as the Company was capitalizing interest expense on its investment while the property was under construction in the prior year period.
