This subpart governs the operation of the investment program, including the rules that TT&L depositaries must follow in crediting and debiting TIP main account balances, SDI account balances, and TIO account balances, and pledging collateral security.

A financial institution must be a collector depositary that accepts term investments, an investor depositary, or a retainer depositary to participate in the investment program. Depositaries electing to participate in the investment program can receive Treasury's investments in obligations of the depositary from the following sources:

(a) FTDs that have been credited to the depositary's TIP main account balance pursuant to subpart C of this part;

(b) EFTPS ACH credit and debit transactions, Fedwire ® non-value transactions, and Fedwire ® value transfers pursuant to subpart B of this part;

(c) Direct investments, SDIs, dynamic investments, and term investments pursuant to subpart D of this part; and

(d) Other excess Treasury operating funds.

(a) Additions. Treasury will invest funds in obligations of collector depositaries that accept term investments, investor depositaries, or retainer depositaries. Such obligations will be in the form of open-ended interest-bearing notes, or in the case of term investments, interest-bearing notes maintained for a predetermined period of time, and additions and reductions will be reflected on the books of the TSC.

(1) PATAX. The TSC will credit the TIP main account balance as stated in § 203.16(a) for an investor or retainer depositary processing tax deposits through PATAX.

(2) EFTPS—(i) ACH debit and ACH credit. The TSC will credit a depositary's TIP main account balance, and credit the depositary's reserve account if capacity exists, for the amount of EFTPS ACH debit and credit entries on the day such entries settle.

(ii) Fedwire ® value and non-value transactions. The TSC will credit a depositary's TIP main account balance if capacity exists, throughout the day on the day of settlement, for the amount of Fedwire ® value and non-value transactions. In the case of Fedwire ® value transactions, the depositary's reserve account will also be credited.

(b) Additional offerings. Other funds from Treasury may be offered from time to time to depositaries participating in the investment program through direct investments, SDIs, term investments, or other investment programs.

(c) Withdrawals. The amount of a TIP main account balance or SDI account balance is payable on demand without prior notice. The TSC will make calls for payment at the direction of the Secretary. On behalf of Treasury, the TSC will debit the depositary's reserve account on the day specified in the call for payment.

(d) Interest. The TIP main account balance and the SDI account balance bear interest at the TT&L rate of interest. Such interest is payable by a charge to the depositary's reserve account in the manner prescribed in the procedural instructions.

(e) Balance limits—(1) Retainer and investor depositaries. A retainer or investor depositary must establish an initial balance limit for its TIP main account balance by providing notice to that effect in writing to the TSC. The balance limit is the amount of funds for which a retainer or investor depositary is willing to provide collateral in accordance with § 203.21(c)(1). The depositary must follow the procedural instructions before reducing the established balance limit unless the reduction results from a collateral revaluation as determined by the FRB. That portion of any PATAX or EFTPS tax payment which, when posted at the FRB, would cause the TIP main account balance to exceed the balance limit specified by the depositary, will be withdrawn by the FRB that day.

(2) Direct investments. An investor depositary that participates in direct investments must set a balance limit for direct investment purposes which is higher than the peak balance normally generated by the depositary's PATAX and EFTPS tax payment inflow. The depositary must follow the procedural instructions before reducing the established balance limit.

(3) SDIs. SDIs are credited to the SDI account balance and are not considered in setting the amount of the TIP main account balance limit or in determining the amounts to be withdrawn where a depositary exceeds its TIP main account balance limit.

(f) TIO. Treasury may, from time to time, invest excess operating funds in obligations of depositaries awarded funds under TIO. Such obligations will be in the form of interest-bearing notes payable upon a predetermined period of time not to exceed 90 days. Such notes will bear interest at a rate prescribed by the Secretary by auction or otherwise taking into consideration prevailing market interest rates.

Financial institutions that process EFTPS tax payments, but that are not TT&L depositaries, have no collateral requirements under this part. Financial institutions that are TT&L depositaries have collateral security requirements, as follows:

(a) Investor and retainer depositaries—(1) PATAX and EFTPS tax payments. Investor and retainer depositaries must pledge collateral security in accordance with the requirements of paragraphs (c)(l), (d), and (e) of this section in an amount that is sufficient to cover the TIP main account balance and the balance in the TT&L account that exceeds the recognized insurance coverage.

(2) Direct investments. An investor depositary is required to pledge collateral in accordance with the requirements of paragraphs (c), (d), and (e) of this section no later than the day before a direct investment is placed. However, each investor depositary participating in same-day direct investments must pledge, prior to the announcement, collateral up to its balance limit to obtain the depositary's maximum portion of the same-day direct investment.

(3) SDIs. The day before SDIs are credited to an investor depositary's SDI account balance, the depositary must pledge collateral security, in accordance with the requirements of paragraphs (c)(2), (d), and (e) of this section, to cover the total of the SDIs to be received.

(4) TIO. Each depositary participating in the term investment program must pledge, prior to the time the term investment is placed, collateral in accordance with paragraphs (c)(1), (c)(2) for certain term investments as determined by Treasury, (d), and (e) of this section sufficient to cover the total TIO account balance.

(b) Collector depositaries. Prior to crediting FTD deposits to the TT&L account, a collector depositary must pledge collateral security, in accordance with the requirements of paragraphs (c)(1), (d), and (e) of this section, in an amount which is sufficient to cover the balance in the TT&L account that exceeds the recognized insurance coverage.

(c) Deposits of securities. (1) Collateral security required under paragraphs (a)(1), (2), (4) (except as provided in subparagraph (2) below), and (b) of this section must be deposited with the depositary's FRB, or with a custodian or custodians within the United States designated by the TSC or FRB, under terms and conditions prescribed by the TSC or FRB.

(2) A depositary pledging collateral security as required under paragraph (a)(3) or paragraph (a)(4) (when permitted) of this section must pledge the collateral under a written security agreement on a form provided by the FRB. The collateral security pledged to satisfy the requirements of paragraphs (a)(3) and (a)(4) (when permitted) of this section may remain in the pledging depositary's possession provided that the pledging is evidenced by advices of custody incorporated by reference in the written security agreement. The depositary must provide the written security agreement and all advices of custody covering collateral security pledged under that agreement to the FRB. Collateral security pledged under the agreement may not be substituted for or released without the advance approval of the FRB, and any collateral security subject to the security agreement will remain so subject until an approved substitution is made. No substitution or release will be approved until an advice of custody containing the description required by the written security agreement is received by the FRB.

(3) Treasury's security interest in collateral security pledged by a depositary in accordance with paragraphs (c)(2) of this section to secure SDIs and certain term investments is perfected without Treasury taking possession of the collateral security by filing or, absent filing, for a period not to exceed 20 calendar days from the day of the depositary's receipt of the special direct or term investment.

(d) Acceptable collateral. The types of securities that may be used as collateral, and how those securities are valued, are set forth in 31 CFR part 380.

(e) Assignment of securities. By pledging acceptable securities which are not negotiable without the depositary's endorsement or assignment, a TT&L depositary, in lieu of placing its unqualified endorsement on each security, appoints the FRB or its assigns as the depositary's attorney-in-fact with full irrevocable power and authority to endorse, assign or transfer the securities, and represents and warrants that an appropriate resolution authorizing the granting of such irrevocable power of attorney has been executed and adopted. The powers of attorney so granted are coupled with an interest and are irrevocable, and full power of substitution is granted to the assignee or holder.

(f) Effecting payments of principal and interest on securities or instruments pledged as collateral—(1) General. Treasury, without notice or demand, may sell or otherwise collect the proceeds of all or part of the collateral, including additions, substitutions, interest, and distribution of principal, and apply the proceeds to satisfy any claims of the United States against the depositary, if any of the following events occur:

(i) The depositary fails to pay, when due, the whole or any part of the funds received by it for credit to the TT&L account and, if applicable, its TIP main account balance, SDI account balance, or TIO account balance;

(ii) The depositary fails to pay when due amounts owed to the United States or the United States Treasury;

(iii) The depositary otherwise violates or fails to perform any of the terms of this part or any of the procedural instructions entered into hereunder; or

(iv) The depositary is closed for business by regulatory action or by proper corporate action, or a receiver, conservator, liquidator, or any other officer is appointed for the depositary. All principal and interest payments on any security pledged to protect the TIP main account balance, the SDI account balance, the TIO account balance or the TT&L account, as applicable, due as of the date of the insolvency or closure or thereafter becoming due, will be held separate and apart from any other assets and will constitute a part of the pledged security available to satisfy any claim of the United States.

(2) Payment procedures. (i) Subject to the waiver in paragraph (f)(2)(iii) of this section, each depositary (including, with respect to such depositary, an assignee for the benefit of creditors, a trustee in bankruptcy, or a receiver in equity) will, as soon as possible, remit to the FRB, as Fiscal agent, each payment of principal and/or interest received by it with respect to collateral pledged pursuant to this section. The remittance will be made no later than 10 days after receipt of such a payment.

(ii) Subject to the waiver in paragraph (f)(2)(iii) of this section, each obligor on a security pledged by a depositary pursuant to this section, upon notification that Treasury is entitled to any payment associated with that pledged security, must make each payment of principal and/or interest due with respect to such security directly to the FRB, as Fiscal agent of the United States.

(iii) The requirements of paragraphs (f)(2)(i) and (ii) of this section are hereby waived for only so long as a pledging depositary avoids both termination from the program under § 203.7 and also those circumstances identified in paragraph (f)(1) which may lead to the collection of the proceeds of collateral or the waiver is otherwise terminated by Treasury.
