| (a) | Includes the actuarially determined liability and certain deferred revenues related to the SPG program. |
We defer gains realized in connection with the sale of a property for which we continue to manage through a long-term management agreement and recognize the gains over the initial term of the related agreement (see Note 11).
The decrease in benefit plan liabilities is primarily the result of changes in the actuarial pension assumptions associated with our pension plans (see Note 18).
