This element represents the recognition of revenue during the period for retail land sales which had been deferred due to such revenue being associated with the liability of the land developer (seller) as its obligation to complete improvements to land, which improvements were a component of the sales transaction. Such amount is generally recognized in revenue as the improvements are completed (percentage-of-completion).
