This document discusses pre-adjusted and post-adjusted trial balances. A pre-adjusted trial balance does not include any balance day adjustments, while a post-adjusted trial balance does include these adjustments. The document provides an example of a business, Smith & Co, and shows their pre-adjusted and post-adjusted trial balances on March 31, 2015. It notes that accrued wages of $400 were not included in the pre-adjusted trial balance but were added in the post-adjusted trial balance through an adjusting entry. The impact of adjustments on the financial reports is also briefly explained.
