[1] The conditions that were considered prohibited forms of continuing involvement related to our sale of the Golf Course Properties (see Note 11) are no longer considered continuing involvement under the new revenue recognition standard. As of result of adopting the new standard on a full retrospective basis, we are now reflecting this transaction as a completed sale in the period in which it occurred.

[2] Adjustments are primarily related to the reclassification of assets and liabilities in accordance with the new accounting and disclosure requirements.
