and\n\n(b) the unmodulated capped production credit worked out by the Secretary for an MVP for a particular quarter is to be modulated:\n\n(i) by multiplying the amount of that credit by the production modulation rate for that quarter, determined under Part 3; and\n\n(ii) by multiplying the amount obtained under subparagraph (i) by the 5% cap rate for the MVP for that quarter, determined under Part 4.\n\n(2) However, subsections (3) and (4) apply if, after the modulated credit for an MVP for a particular quarter has been worked out under subsection (1) and issued to the MVP:\n\n(a) the Secretary is required to amend the ACIS ledger, under section 66 of the Act, to give effect to a decision of the Administrative Appeals Tribunal or of a court, or to correct an error in the ledger; and\n\n(b) in giving effect to the decision or in correcting the error, the unmodulated uncapped production credit, or the unmodulated capped production credit, worked out for the MVP for that particular quarter (the revised amount) exceeds the amount of that credit (the original amount) used to work out the modulated credit.\n\n(3) The additional amount of unmodulated uncapped production credit worked out for the MVP for that particular quarter is to be modulated by multiplying that amount by the 5% cap rate for the MVP for the additional amount, determined under Part 4.\n\n(4) The additional amount of unmodulated capped production credit worked out for the MVP for that particular quarter is to be modulated:\n\n(a) by multiplying that amount by the production modulation rate for the additional amount, determined under Part 3; and\n\n(b) by multiplying the amount obtained under paragraph (a) by the 5% cap rate for the MVP for the additional amount, determined under Part 4.\n\n(5) In this section:\n\n> additional amount means the amount by which the revised amount exceeds the original amount.\n\n6 Modulation of investment credit\n\n(1) For sections 57 and 59 of the Act, the unmodulated investment credit worked out by the Secretary for an MVP, ACP, AMTP and ASP for a particular quarter is to be modulated:\n\n(a) by multiplying the amount of that credit by the investment modulation rate for that quarter, determined under Part 3; and\n\n(b) by multiplying the amount obtained under paragraph (a) by the 5% cap rate for the participant for that quarter, determined under Part 4.\n\n(2) However, subsection (3) applies if, after the modulated credit for a participant for a particular quarter has been worked out under subsection (1) and issued to the participant:\n\n(a) the Secretary is required to amend the ACIS ledger, under section 66 of the Act, to give effect to a decision of the Administrative Appeals Tribunal or of a court, or to correct an error in the ledger; and\n\n(b) in giving effect to the decision or in correcting the error, the unmodulated investment credit worked out for the participant for that particular quarter (the revised amount) exceeds the amount of that credit (the original amount) used to work out the modulated credit.\n\n(3) The additional amount of the unmodulated investment credit worked out for the participant for that particular quarter is to be modulated:\n\n(a) by multiplying that amount by the investment modulation rate for the additional amount, determined under Part 3; and\n\n(b) by multiplying the amount obtained under paragraph (a) by the 5% cap rate for the participant for the additional amount, determined under Part 4.\n\n(4) In this section:\n\n> additional amount means the amount by which the revised amount exceeds the original amount.\n\n \n\nPart 3 Determination of modulation rates\n\nDivision 1 Modulation rates for a quarter other than the final quarter\n\n7 Definitions\n\nIn this Division:\n\n> remaining ACIS year, means an ACIS year in which at least 1 remaining quarter lies.\n\n> remaining quarter, in relation to the determination of an investment modulation rate or a production modulation rate, means a quarter in an ACIS year for which modulated credit has not been issued to participants as duty credit at the time of determining the investment modulation rate or production modulation rate.\n\n> total expected capped credit, for a participant for an ACIS year, means the sum of:\n\n(a) the total amount of any additional amount of unmodulated capped production credit and unmodulated investment credit for the participant worked out to date during a remaining quarter in that year; and\n\n(b) the total amount of expected unmodulated capped production credit, determined under section 10, for the participant for all remaining quarters in that year; and\n\n(c) the total amount of expected unmodulated investment credit, determined under section 10, for the participant for all remaining quarters in that year.\n\n> total expected credit, for a participant for an ACIS year, means the sum of:\n\n(a) the total amount of modulated credit issued to date to the participant as duty credit during that year;
