This includes, but not limited to, business practices, loss provisions and loss indexes, transmission tariff rates, and other ancillary services rate schedules.

Transmission service agreements executed under the October 2001 OATT (http://www.oatioasis.com/LDWP/LDWPdocs/OATT_October_2001_REV_2.doc) will be automatically transferred to the new OATT. The anticipated effective date for the new OATT is 6/1/2007 or later.
