Controlled Accumulation Period The Controlled Accumulation Period is scheduled to commence at the beginning of business on the Controlled Accumulation Date. On each Determination Date until the Controlled Accumulation Date, the Issuer shall review the amount of expected Principal Collections and determine the Controlled Accumulation Period Length; provided, that if the Controlled Accumulation Period Length (determined as described below) on any Determination Date is less than or more than the number of months in the scheduled Controlled Accumulation Period, upon written notice to the Indenture Trustee, with a copy to each Rating Agency, the Issuer shall either postpone or accelerate, as applicable, the Controlled Accumulation Date, so that as a result, the number of Monthly Periods in the Controlled Accumulation Period will equal the Controlled Accumulation Period Length; provided, that the length of the Controlled Accumulation Period will not be less than one (1) month. The “Controlled Accumulation Period Length” will mean a number of whole months such that the amount available for payment of principal on the Notes and the reduction of the Principal Overcollateralization Amount on the Expected Principal Payment Date is expected to equal or exceed the Note Principal Balance plus the Principal Overcollateralization Amount, assuming for this purpose that (1) the weighted average principal payment rate on the Receivables held by the Issuer will be no greater than the lowest weighted average monthly principal payment rate for the Receivables held by the Issuer for the prior twelve (12) Monthly Periods, (2) the total amount of Principal Receivables held by the Issuer in the Trust (and the principal amount on deposit in the Excess Funding Account, if any) remains constant at the level on such date of determination, (3) no Early Amortization Event with respect to any Series will subsequently occur and (4) no additional Series (other than any Series being issued on such date of determination) will be subsequently issued by the Issuer. Any notice by the Issuer modifying the commencement of the Controlled Accumulation Period pursuant to this Section 4.12 shall specify (i) the Controlled Accumulation Period Length and (ii) the commencement date of the Controlled Accumulation Period.
