BPPR shall ensure that the securities and other property of the Fund are maintained separate and apart from the assets of the other clients of BPPR or any sub-custodian appointed hereunder and from the assets of BPPR or such sub-custodian, as the case may be, and shall mark or direct the marking of such securities and other property to identify them as belonging to the Fund. BPPR shall not be responsible for any securities or other property of the Fund not actually received by BPPR or its authorized agent (including any sub-custodian appointed hereunder).

The Fund shall bear all risk with respect to losses that arise from late or incorrect payment or collectability of any check that pertains to any such income; however, BPPR and JPM or any other such sub-custodian shall take all reasonable steps in monitoring the timeliness and accuracy of all payments.

3.        Unless otherwise instructed to the contrary by the Fund, BPPR shall direct JPM or any other such sub-custodian to present for payment and collect the amount payable upon such securities that are called, but only if either BPPR receives a written notice of such call, or notice of such call appears in one or more of the publications as may be agreed upon by the Fund and such sub-custodian as directed by BPPR, which may be amended at any time by BPPR or JPM or any other such custodian, without the prior notification or consent of the Fund; present for payment and collect the amount payable upon all securities that mature; surrender securities in temporary form for definitive securities; hold directly, or through an authorized book-entry system, depository, or agent or futures commission merchant (“FCM”), with respect to assets therein deposited, for the sole account of the Fund designated as such on the records of JPM or such other sub-custodian as directed by BPPR, e.g., “JPM as Sub-Custodian for the [insert Fund name]” and maintained in the book-entry system or a depository or by an agent, assets deposited therewith or all rights and similar property issued with respect to such assets so held for the Fund; to transfer to FCMs cash or other assets of the Fund as initial and variation margin; and to establish segregated accounts for repurchase agreements, put options, margin assets, and for such other purposes as the Fund’s administrator or the Fund’s investment adviser may reasonably request.

Such written confirmation, notice, or report shall also specify the place and manner in which such securities and other property are being maintained. (If and when there is any change in the place and manner in which such securities or other property are being maintained. BPPR shall give the Fund written notice thereof.) BPPR shall presume that the Fund agrees with the correctness of the contents of any statement, report or notice BPPR provides pursuant to this Agreement unless the Fund notifies BPPR otherwise within fifteen (15) days after receipt thereof, exclusive of Saturdays, Sundays, and legal holidays in the Commonwealth of Puerto Rico.

5.        JPM or any other such sub-custodian, as directed by BPPR, is hereby authorized to hold any securities and other property in bearer form or nominee name.

6.        Upon receipt of specific instructions from the Fund and not otherwise, BPPR and JPM or any other such sub-custodian shall deliver any or all of the property held hereunder only upon delivery of payment, unless any or all of the property held hereunder is subject to a collateral or pledge agreement set forth between with the Fund whereby restrictions as to the disposition of said collateral or property have been established.
