Variable Accumulation Period The Controlled Accumulation Period is scheduled to commence on the Stated Controlled Accumulation Period Commencement Date; provided, however, that if the Controlled Accumulation Period Length (determined as described below) on any Determination Date is different from the Initial Scheduled Controlled Accumulation Period Length, the Servicer, at its option on any Determination Date prior to the commencement of the Controlled Accumulation Period, may elect to modify the date on which the Controlled Accumulation Period actually commences to the last Business Day of any Due Period that precedes the Due Period that is the number of Due Periods prior to the Expected Final Payment Date equal to the Controlled Accumulation Period Length. Such election will be set forth in the Monthly Servicer Certificate. If the Servicer elects to modify the date on which the Controlled Accumulation Period commences pursuant to this Section 19, then on each Determination Date thereafter until the date on which the Controlled Accumulation Period commences the Servicer will recalculate the Controlled Accumulation Period Length; provided, however, that (i) the length of the Controlled Accumulation Period will not be less than the Minimum Controlled Accumulation Period Length and (ii) notwithstanding any other provision of this Series Supplement to the contrary, no election to postpone the commencement of the Controlled Accumulation Period shall be made after a Rapid Amortization Event (as described herein or in the applicable Series Supplement) shall have occurred for so long as it is continuing with respect to any Series in the Group to which the Series established hereby belongs. On each Determination Date, the Servicer will determine the "Controlled Accumulation Period Length" that will equal the number of Due Periods such that the Class Controlled Accumulation Amount for the Due Period related to the Class Expected Final Payment Date, when aggregated with the Class Controlled Accumulation Amounts for each preceding Due Period, will equal or exceed the Series Initial Investor Interest. Any notice by the Servicer electing to modify the commencement of the Controlled Accumulation Period pursuant to this Section 19 shall specify the following as determined on such Determination Date: (i) the Controlled Accumulation Period Length; (ii) the commencement date of the Controlled Accumulation Period; and (iii) the Class Controlled Accumulation Amount with respect to each class of such Series with respect to each Due Period. If the Controlled Accumulation Period Length as recalculated on any such Determination Date exceeds the number of full Due Periods following such Determination Date and preceding the Class A Expected Final Payment Date, the commencement date of the Controlled Accumulation Period will be such Determination Date.
