[1] Deferred revenue predominately relates to hunting and other access rights on our timberlands, payments received for lumber shipments where control of goods have not transferred, member related activities at an owned country club and certain post-close obligations for real estate sales. These contract liabilities are recognized over the term of the contracts, which is typically twelve months or less, except for country club initiation fees which are recognized over the average life of club membership.
