Land Sales Revenues
Land sales revenues and cost of revenues are recorded at the time that title and possession of the property have been transferred to the buyer. We recognize the pro rata share of revenues and cost of revenues of land sales to entities in which we have a 50% or less interest based upon the ownership percentage attributable to the non-Company investors. Any profit not recognized in a transaction reduces our investment in the entity.
