Material Instances of Noncompliance

 

1.       *1122(d)(2)(i) Payments on pool assets are deposited into the appropriate custodial bank accounts and related bank clearing accounts no morethan two business days following receipt, or such other number of days specified in the transaction agreements. * With respect to certain transactions for which the transaction documents require that funds be deposited into the custodial bank accounts on theday funds are received by the Company, funds were not deposited to the custodial bank accounts in accordance with the terms of the transaction documents.  In a sample of selected payments on pool assets received by the Company, this finding was identifiedonce.  In that instance, the funds received were deposited into the specified custodial account on the day after the day they were received.  As the one-day delay only impacted investment income to which the Company was entitled as compensation for itsservices as securities administrator, management believes that the delay did not affect the amount of any payments to any security holder or to any transaction party other than the Company. 

2.       *1122(d)(3)(ii) Amounts due to investors are allocated and remitted in accordance with timeframes, distribution priority and other terms setforth in the transaction agreements.*  With respect to certain remittances during the reporting period, amounts due to investors were allocated and remitted in accordance with distribution priority and other terms set forth in the transaction agreements, butwere not paid timely to investors.
