 Securities and Exchange Commission [Release No. 34-98589; File No. SR-NSCC-2023-009]
 Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”) [1]
                    
                     and Rule 19b-4 thereunder,[2]
                    
                     notice is hereby given that on September 22, 2023, National Securities Clearing Corporation (“NSCC”) filed with the Securities and Exchange Commission (“Commission”) the proposed rule change as described in Items I, II and III below, which Items have been primarily prepared by the clearing agency. The Commission is publishing this notice to solicit comments on the proposed rule change from interested persons. I. Clearing Agency's Statement of the Terms of Substance of the Proposed Rule Change The proposed rule change consists of modifications to NSCC's Rules & Procedures (“Rules”) [3]
                    
                     in order to modify the schedule of haircuts for Eligible Clearing Fund Securities and remove it from Procedure XV of the Rules (“Procedure XV”), and make other clarifying changes, as described in greater detail below. II. Clearing Agency's Statement of the Purpose of, and Statutory Basis for, the Proposed Rule Change In its filing with the Commission, the clearing agency included statements concerning the purpose of and basis for the proposed rule change and discussed any comments it received on the proposed rule change. The text of these statements may be examined at the places specified in Item IV below. The clearing agency has prepared summaries, set forth in sections A, B, and C below, of the most significant aspects of such statements. (A) Clearing Agency's Statement of the Purpose of, and Statutory Basis for, the Proposed Rule Change 1. Purpose NSCC is proposing to modify the schedule of haircuts for Eligible Clearing Fund Securities, and to remove it and the related concentration limits from Procedure XV, and make other clarifying changes, as described in greater detail below. Background As part of its market risk management strategy, NSCC manages its credit exposure to members by determining the appropriate Required Fund Deposits to the Clearing Fund and monitoring its sufficiency, as provided for in the Rules.[4]
                    
                     The Required Fund Deposit serves as each member's margin. The objective of a member's Required Fund Deposit is to mitigate potential losses to NSCC associated with liquidating a member's portfolio in the event NSCC ceases to act for that member (hereinafter referred to as a “default”).[5]
                    
                     The aggregate of all members' Required Fund Deposits constitutes the Clearing Fund of NSCC. NSCC would access its Clearing Fund should a defaulting member's own Required Fund Deposit be insufficient to satisfy losses to NSCC caused by the liquidation of that member's portfolio. The Clearing Fund reduces the risk that NSCC would need to mutualize any losses among non-defaulting members during the liquidation process. Under Rule 4 (Clearing Fund), members are required to make deposits to the Clearing Fund, with the amount of each member's Required Fund Deposit being determined by NSCC in accordance with Rule 4. A member may satisfy its Required Fund Deposit with cash or an open account indebtedness secured by Eligible Clearing Fund Securities.[6]
                    
                     Eligible Clearing Fund Securities, comprised of certain agency, mortgage-backed, and Treasury securities, are valued based on the prior Business Day's closing market price, less a haircut, and may be subject to a concentration limit.[7]
                    
                     Haircuts are used to protect NSCC and its members from price fluctuations, 
                    *i.e.,*
                     if NSCC is required to liquidate collateral of an insolvent member and such collateral is worth less at the time of liquidation than when it is pledged to NSCC. Concentration limits are intended to reduce NSCC's risk by limiting the percentage of certain types of Eligible Clearing Fund Securities pledged by members to secure the Clearing Fund deposits. This is because when a member's portfolio contains large net unsettled positions in a particular group of securities with a similar risk profile or in a particular asset type, such securities could present additional risk to NSCC. Currently, collateral haircuts applicable to relevant security types and remaining maturity terms are specified as fixed percentages in Section III.(A) of Procedure XV (“Section III.(A)”).[8]
                    
                     The sufficiency of collateral haircuts is evaluated through use of back-tests, stress-tests and market observations. To ensure the sufficiency of the collateral haircuts, a backtesting analysis of members' collateral deposits is conducted daily, and summary reviews are completed quarterly, each by the NSCC market risk group pursuant to NSCC's internal market risk management policies and procedures. NSCC performs daily backtesting of collateral by comparing the collateral haircut for each member in simulated liquidations with the member's actual collateral held on deposit at NSCC. Any exceptions noted are escalated to management daily to assess the root cause and determine whether further analysis and/or review would be appropriate. Specifically, if NSCC determines that a particular security may present inherent volatility and/or liquidity risks that could likely result in an erosion in the value of the security exceeding the applicable collateral 
                    ( print page 68778)
                    haircut, ad hoc reviews may be conducted by risk management pursuant to NSCC's internal market risk management procedures. On a quarterly basis, NSCC reviews and identifies instances where the simulated losses from available historical stress testing scenario dates have exceeded the collateral haircut values. In addition, each quarter, NSCC reviews the composition of the Eligible Clearing Fund Securities that members have pledged to secure their Required Fund Deposits in order to assess the sufficiency of the collateral haircuts applied and whether any haircut changes would be needed. In addition to collateral haircuts, NSCC applies concentration limits to certain Eligible Clearing Fund Securities. Currently, the concentration limits applicable to certain Eligible Clearing Fund Securities are specified in subsections (a) and (b) of Section II.(A)1. of Procedure XV (“Section II.(A)1.”).[9]
                    
                     Specifically, subsection (a) provides any deposits of Eligible Clearing Fund Agency Securities or Eligible Clearing Fund Mortgage-Backed Securities in excess of 25 percent of a member's Required Fund Deposit will be subject to a haircut that is twice the amount of the percentage noted in Section III.(A). In addition, footnote 7 of subsection (a) of Section II.(A)1. provides that a member that is an Agency may not pledge Eligible Clearing Fund Agency Securities of which it is the issuer. Footnote 8 of subsection (a) provides that with regard to a member that pledges Eligible Clearing Fund Mortgage-Backed Securities of which it is the issuer, such collateral will be subject to a premium haircut as specified in Section III.(A). Subsection (b) of Section II.(A)1. provides that no more than 20 percent of a member's Required Fund Deposit may be in the form of Eligible Clearing Fund Agency Securities that are of a single issuer. Changes to the collateral haircuts and concentration limits are currently subject to NSCC's internal governance process and would remain so with respect to the haircut schedule changes made in accordance with this proposal. If NSCC determines that, based on the analyses that it performs, there is insufficient/excessive collateral haircut/concentration due to an identifiable cause that affected multiple members and such cause would likely persist based on NSCC's assessment of market conditions, such outcome or result could cause NSCC to amend the haircuts/concentration limits in the haircut schedule. If NSCC determines that a change to the haircut schedule is warranted, its market risk group would document the recommendation and rationale for the change at the time of such determination and obtain approval from an executive director or above with a notice to the risk management committee, in accordance with NSCC's internal market risk management policies and procedures. Before making adjustments to the haircut schedule, NSCC measures the potential impact of such adjustments to ensure any impact is both necessary and appropriate. Through its review, NSCC has observed that under volatile market conditions with elevated frequency and magnitude of securities price movements, the collateral value of Eligible Clearing Fund Securities may shift in a relatively short period of time and the current haircuts may not sufficiently account for the change in value. When the erosion in the value of the Eligible Clearing Fund Securities exceeds the relevant haircuts, NSCC is exposed to increased risk of potential losses associated with liquidating a member's portfolio in the event of a member default when the defaulting member's own margin is insufficient to satisfy losses to NSCC caused by the liquidation of that member's portfolio. Similarly, when a member's portfolio contains large net unsettled positions in a particular group of securities with a similar risk profile or in a particular asset type, such securities could present additional risk to NSCC. The additional risk exposures associated with liquidating a member's portfolio in the event of a member default could lead to an increase in the likelihood that NSCC would need to mutualize losses among non-defaulting members during the liquidation process. However, any changes to the haircuts and/or concentration limits currently requires a proposed rule change to be filed with the Commission. In order to provide NSCC with more flexibility in adjusting the haircuts and concentration limits so NSCC can respond to changing market conditions more promptly in order to mitigate the additional risk exposure, NSCC is proposing to remove Section III.(A) and concentration limits from the Rules, and to publish the haircuts and concentration limits in a haircut schedule on NSCC's website. Specifically, NSCC is proposing to delete subsections (a) and (b) of Section II.(A)1., and delete Section III of Procedure XV. Currently, subsections (a) and (b) of Section II.(A)1. set out certain concentration limits for Eligible Clearing Fund Agency Securities and Eligible Clearing Fund Mortgage-Backed Securities. Subsection (a) provides that any deposits of Eligible Clearing Fund Agency Securities or Eligible Clearing Fund Mortgage-Backed Securities, respectively, in excess of 25 percent of a member's Required Fund Deposit will be subject to an additional haircut equal to twice the percentage as specified in Section III.(A). In addition, footnote 8 of subsection (a) provides that with regard to a member that pledges Eligible Clearing Fund Mortgage-Backed Securities of which it is the issuer, such collateral will be subject to a premium haircut as specified in Section III.(A). The same language from subsection (a) and footnote 8 of Section II.(A)1. is in Section III.(A). Having this language in both the Rules and the proposed haircut schedule is unnecessary and could potentially create confusion for members. As such, NSCC is proposing to eliminate this duplication by deleting subsection (a) and footnote 8 of Section II.(A)1., and including this language in the proposed haircut schedule. Subsection (b) of Section II.(A)1. currently sets out an additional concentration limit with respect to Eligible Clearing Fund Agency Securities. Specifically, subsection (b) provides that no more than 20 percent of the Required Fund Deposit may be in the form of Eligible Clearing Fund Agency Securities that are of a single issuer. In addition, footnote 7 of subsection (a) provides that a member that is an Agency may not pledge Eligible Agency Securities of which it is the issuer. NSCC is proposing to delete subsection (b) and footnote 7 of Section II.(A)1., and move this language to the proposed haircut schedule. For clarity, NSCC is also proposing to revise the language currently in footnote 7 of Section II.(A)1. to provide that no member may pledge Eligible Clearing Fund Agency Securities of which it is the issuer to secure its Required Fund Deposit. NSCC would also add “Clearing Fund” in the reference to “Eligible Agency Securities” currently in the language in subsection (b) of Section II.(A)1. to reflect the correct defined term for Eligible Clearing Fund Agency Securities, and move “may be” earlier in the first sentence for clarity. Furthermore, NSCC is proposing to add language in Section II.(A)1. that makes it clear that all Eligible Clearing Fund Securities pledged to secure Clearing Fund deposits shall, for collateral valuation purposes, be subject to a haircut and may be subject to a concentration limit. The proposed language would provide that NSCC shall determine the applicable haircuts and any concentration limits from time to time in accordance with its internal 
                    ( print page 68779)
                    policy and governance process, based on factors determined to be relevant by NSCC, which may include, for example, backtesting results and NSCC's assessment of market conditions, in order to set appropriately conservative haircuts and/or concentration limits for the Eligible Clearing Fund Securities and minimize backtesting deficiency occurrences. The proposed language would also provide that the haircuts and any concentration limits prescribed by NSCC shall be set forth in a haircut schedule that is published on NSCC's website and that it shall be the member's responsibility to retrieve the haircut schedule. Section II.(A)1. would also indicate that NSCC will provide members with at a minimum one Business Day's advance notice of any change in the haircut schedule. NSCC is proposing to delete Section III of Procedure XV, which contains the haircut schedule. In addition, NSCC is proposing to (i) remove references to Section III of Procedure XV in two places in Rule 4, and replace them with a reference to Section II.(A) of Procedure XV in each case, (ii) remove references to subsections 1(a) and (b) of Section II.(A) of Procedure XV and references to Section III of Procedure XV in Rule 56 and (iii) remove a reference to Section III of Procedure XV in Section II.(A) of Procedure XV, and replace it with a reference to the proposed haircut schedule, to reflect the proposed changes described above. NSCC is also proposing to make some punctuation and grammar changes and add a reference to Procedure XV in Section 12(c) of Rule 56 to clarify the language. Finally, NSCC is proposing to clarify some language in Sections I.(B)(1), II.(A), II.(B), II.(C) and II.(D) of Procedure XV to reflect that Mutual Fund/Insurance Services Members and other Limited Members are no longer required to make deposits into the Clearing Fund. In 2022, NSCC removed the requirement that any Limited Members, including Mutual Fund/Insurance Services Members, make any deposits to the Clearing Fund.[10]
                    
                     Sections I.(B)(1), II.(A), II.(B), II.(C) and II.(D) of Procedure XV still contain references to Mutual Fund/Insurance Service Members and/or Limited Members making deposits into the Clearing Fund, and NSCC is proposing to remove those references for clarity. NSCC believes that the proposed change to move the haircuts and concentration limits from the Rules to the website would enable NSCC to adjust the haircuts and concentration limits without undergoing a rule filing process.[11]
                    
                     By being able to make appropriate and timely adjustments to the haircuts and concentration limits, NSCC would have the flexibility to respond to changing market conditions more promptly. Having the flexibility to respond to changing market conditions more promptly would in turn help better ensure that NSCC collects sufficient margin from members as well as risk manages its credit exposures to its members. The proposed change would also align NSCC with the manner in which its affiliate, The Depository Trust Company (“DTC”), provides haircut schedules to participants.[12] Concurrent with moving the haircuts and concentration limits from the Rules to the website, NSCC is also proposing to reconfigure the categories relating to Treasury securities haircuts by moving the Treasury Inflation-Protected Securities (“TIPS”) to a separate category and increasing the haircut levels for TIPS. The proposed change to TIPS is reflected in Exhibit 3c to this filing. TIPS are a type of Treasury security issued by the U.S. government that are indexed to inflation such that the principal value of the security rises as inflation rises. In connection with NSCC's assessments of its collateral haircuts, NSCC employs daily backtesting to determine the adequacy of each member's collateral haircuts. NSCC compares the collateral haircuts for each member with the simulated liquidation gains/losses using the actual positions in the member's portfolio, and the actual historical security returns. A backtesting deficiency occurs when a member's collateral haircuts would not have been adequate to cover the simulated liquidation losses. In connection with such assessments, NSCC has determined that in periods where the inflation rate fluctuates, the current haircut levels for TIPS may be inadequate to address the fluctuations from time to time. This is because TIPS are indexed to the inflation rate, and prices on TIPS move inversely to their yields, 
                    *e.g.,*
                     when the inflation rate increases, prices on TIPS decrease. When the decline in market value of TIPS exceeds the haircut for TIPS, NSCC would be exposed to potential liquidation losses. Accordingly, NSCC is proposing to reconfigure and modify the haircut information that would be posted on NSCC's website to ensure that the haircut levels would be commensurate with the particular risk attributes of TIPS. Specifically, NSCC would list TIPS of various maturity groupings in a separate category from Treasury bills, notes and bonds. In addition, NSCC would change the haircut level applicable for TIPS as follows: Maturity
Current
                             %
Proposed
                             %TIPS
Zero to 1 year
2.0
2.01 year to 2 years
2.0
3.02 years to 5 years
3.0
5.05 years to 10 years
4.0
7.010 years to 15 years
6.0
7.015 years or greater
6.0
10.0
 In determining the appropriate haircut levels for TIPS, NSCC conducted a review of TIPS haircuts at other registered clearing agencies and foreign central counterparty clearing houses (“CCPs”) to compare NSCC's current TIPS haircuts with that required by registered clearing agencies and foreign CCPs when TIPS are deposited to their clearing funds, or the equivalent thereof. The results of the review and comparison indicated that NSCC's current haircut levels for TIPS are generally lower than the TIPS haircuts required by other clearing agencies and 
                    ( print page 68780)
                    foreign CCPs, particularly with respect to maturity ranges of 10 years or longer. While the TIPS haircut requirement at such other entities is not dispositive as to the risk borne by NSCC or the proper TIPS haircut levels to offset such risk, it is indicative of the TIPS haircuts being applied to users of other similarly situated entities in order to use the services of the clearing agencies and foreign CCPs and the impact to such users. The chart below shows the haircuts that participants of other clearing agencies and foreign CCPs are currently subject to when using TIPS to meet their margin requirements, as compared with the existing TIPS haircuts required at NSCC.  NSCC is not proposing any changes to the concentration limits at this time. Impact Study NSCC conducted an impact study for the period from September 1, 2021 through August 31, 2022 (“Impact Study”). If the proposed haircut adjustments had been in place during the Impact Study period, the changes would have resulted in an average daily increase of $197,000 in the Clearing Fund assuming TIPS were deposited. Two members would have been impacted with a daily average dollar increase of approximately $123,000 (or 0.10% of their average Clearing Fund deposit) and $74,000 (or 0.31% of their average Clearing Fund deposit), respectively, had the proposed changes been in place. Implementation Timeframe Subject to approval by the Commission, NSCC expects to implement this proposal by no later than 60 Business Days after such approval and would announce the effective date of the proposed changes by an Important Notice posted to NSCC's website. 2. Statutory Basis NSCC believes this proposal is consistent with the requirements of the Act, and the rules and regulations thereunder applicable to a registered clearing agency. Specifically, NSCC believes that the proposed changes described above are consistent with Section 17A(b)(3)(F) of the Act,[17]
                    
                     and Rules 17Ad-22(e)(4)(i), (e)(5), (e)(6)(i), and (e)(6)(v), each promulgated under the Act,[18]
                    
                     for the reasons described below. Section 17A(b)(3)(F) of the Act requires, in part, that the rules of a clearing agency be designed to promote the prompt and accurate clearance and settlement of securities transactions, and to assure the safeguarding of securities and funds which are in the custody or control of the clearing agency or for which it is responsible.[19]
                    
                     As described above, NSCC believes the proposed changes to move the collateral haircuts and concentration limits from the Rules to the website would provide NSCC with more flexibility to respond to changing market conditions because adjustments to the haircuts and concentration limits would no longer require a rule change. By being able to make appropriate and timely adjustments to the haircuts and concentration limits, NSCC would have the flexibility to respond to changing market conditions more promptly. NSCC believes that having this additional flexibility to respond to changing market conditions more promptly would help better ensure that NSCC (i) collects sufficient margin from members to cover the risk exposures that NSCC may face in liquidating members' portfolios and (ii) minimizes exposures from members with large collateral positions in a particular group of securities with a similar risk profile or in a particular asset type, such that, in the event of a member default, NSCC's operations would not be disrupted, and non-defaulting members would not be exposed to losses they cannot anticipate or control. In this way, the proposed rule change to move the collateral haircuts and concentration limits from the Rules to the website would assure the safeguarding of securities and funds which are in the custody and control of NSCC or for 
                    ( print page 68781)
                    which it is responsible, consistent with Section 17A(b)(3)(F) of the Act.[20] NSCC also believes the proposed changes to move TIPS haircuts into a separate category and raise the haircut levels for TIPS would help ensure that the haircut levels for TIPS would be commensurate with the particular risk attributes of TIPS. NSCC has determined that in periods where the inflation rate fluctuates, the current haircut levels for TIPS have been inadequate to address the fluctuations from time to time, and more conservative haircuts for TIPS are warranted. Having haircut levels for TIPS that are commensurate with the particular risk attributes of TIPS would enable NSCC to collect sufficient margin from members to cover the risk exposures that NSCC may face in liquidating members' portfolios such that, in the event of a member default, NSCC's operations would not be disrupted, and non-defaulting members would not be exposed to losses they cannot anticipate or control. In this way, the proposed rule change to move TIPS haircuts into a separate category and raise the haircut levels for TIPS would assure the safeguarding of securities and funds which are in the custody and control of NSCC or for which it is responsible, consistent with Section 17A(b)(3)(F) of the Act.[21] NSCC believes that the proposed clarifying changes would help to ensure that the Rules are clear to members. When members better understand their rights and obligations regarding the Rules, members are more likely to act in accordance with the Rules, which NSCC believes would promote the prompt and accurate clearance and settlement of securities transactions. As such, NSCC believes that the proposed clarifying changes would be consistent with Section 17A(b)(3)(F) of the Act.[22] Rule 17Ad-22(e)(4)(i) under the Act [23]
                    
                     requires a covered clearing agency to establish, implement, maintain and enforce written policies and procedures reasonably designed to effectively identify, measure, monitor, and manage its credit exposures to participants and those exposures arising from its payment, clearing, and settlement processes by maintaining sufficient financial resources to cover its credit exposure to each participant fully with a high degree of confidence. As described above, NSCC believes the proposed changes to move the collateral haircuts and concentration limits from the Rules to the website would provide NSCC with more flexibility to respond to changing market conditions because adjustments to the haircuts and concentration limits would no longer require a rule change. By being able to make appropriate and timely adjustments to the haircuts and concentration limits, NSCC would have the flexibility to respond to changing market conditions more promptly. NSCC believes that having this additional flexibility to respond to changing market conditions more promptly would help ensure that NSCC (i) collects sufficient margin from members to cover the risk exposures that NSCC may face in liquidating members' portfolios and (ii) minimizes exposures from members with large collateral positions in a particular group of securities with a similar risk profile or in a particular asset type, such that, in the event of a member default, NSCC's operations would not be disrupted, and non-defaulting members would not be exposed to losses they cannot anticipate or control. In this way, the proposed rule change to move the collateral haircuts and concentration limits from the Rules to the website would help ensure that NSCC maintains sufficient financial resources to cover its credit exposure to each participant fully with a high degree of confidence, consistent with the requirements of Rule 17Ad-22(e)(4)(i) under the Act.[24] NSCC also believes the proposed changes to move TIPS haircuts into a separate category and raise the haircut levels for TIPS would help ensure that the haircut levels for TIPS would be commensurate with the particular risk attributes of TIPS. NSCC has determined that in periods where the inflation rate fluctuates, the current haircut levels for TIPS may be inadequate to address the fluctuations from time to time, and more conservative haircuts for TIPS are warranted. Ensuring that the haircut levels for TIPS are commensurate with the particular risk attributes of TIPS would in turn help ensure that NSCC requires members to maintain sufficient margin to cover the credit exposures that NSCC may face related to its ability to liquidate members' portfolios in the event of a member default. In this way, the proposed rule change to move TIPS haircuts into a separate category and raise the haircut levels for TIPS would help ensure that NSCC maintains sufficient financial resources to cover its credit exposure to each participant fully with a high degree of confidence, consistent with the requirements of Rule 17Ad-22(e)(4)(i) under the Act.[25] Rule 17Ad-22(e)(5) under the Act [26]
                    
                     requires, in part, a covered clearing agency to establish, implement, maintain and enforce written policies and procedures reasonably designed to set and enforce appropriately conservative haircuts and concentration limits if the covered clearing agency requires collateral to manage its or its participants' credit exposure. As described above, NSCC believes the proposed changes to move the collateral haircuts and concentration limits from the Rules to the website would provide NSCC with more flexibility to respond to changing market conditions because adjustments to the haircuts and concentration limits would no longer require a rule change. By being able to make appropriate and timely adjustments to the haircuts and concentration limits, NSCC would have the flexibility to respond to changing market conditions more promptly. NSCC believes that having this additional flexibility to respond to changing market conditions more promptly would help better ensure that NSCC (i) collects sufficient margin from members to cover the risk exposures that NSCC may face in liquidating members' portfolios and (ii) minimizes exposures from members with large collateral positions in a particular group of securities with a similar risk profile or in a particular asset type, such that, in the event of a member default, NSCC's operations would not be disrupted, and non-defaulting members would not be exposed to losses they cannot anticipate or control. Specifically, NSCC would have the ability to promptly set and enforce conservative collateral haircuts and concentration limits that are reflective of the current market conditions. In this way, the proposed changes to move the collateral haircuts and concentration limits from the Rules to the website would help NSCC set and enforce appropriately conservative collateral haircuts and concentration limits, consistent with the requirements of Rule 17Ad-22(e)(5) under the Act.[27] NSCC also believes the proposed changes to move TIPS haircuts into a separate category and raise the haircut levels for TIPS would help ensure that the haircut levels for TIPS would be commensurate with the particular risk attributes of TIPS. NSCC has determined that in periods where the inflation rate fluctuates, the current haircut levels for TIPS have been inadequate to address the fluctuations from time to time, and more conservative haircuts for TIPS are 
                    ( print page 68782)
                    warranted. Specifically, NSCC would have the ability to set and enforce conservative collateral haircuts that are commensurate with the particular risk attributes of TIPS. In this way, the proposed changes to move TIPS haircuts into a separate category and raise the haircut levels for TIPS would help NSCC set and enforce appropriately conservative collateral haircuts, consistent with the requirements of Rule 17Ad-22(e)(5) under the Act.[28] Rule 17Ad-22(e)(6)(i) under the Act [29]
                    
                     requires a covered clearing agency to establish, implement, maintain and enforce written policies and procedures reasonably designed to cover, if the covered clearing agency provides central counterparty services, its credit exposures to its participants by establishing a risk-based margin system that, at a minimum, considers, and produces margin levels commensurate with, the risks and particular attributes of each relevant product, portfolio, and market. NSCC believes that the proposed changes to move the collateral haircuts and concentration limits from the Rules to the website would provide NSCC with more flexibility to respond to changing market conditions because NSCC would be able to make appropriate adjustments to the haircuts and concentration limits without a rule change. By being able to make appropriate and timely adjustments to the haircuts and concentration limits, NSCC would have the flexibility to respond to changing market conditions more promptly. NSCC believes that having this additional flexibility to respond to changing market conditions more promptly would enable NSCC to better risk manage its credit exposure to its members by (i) collecting sufficient margin from members to cover the risk exposures that NSCC may face in liquidating members' portfolios and (ii) minimizing exposures from members with large collateral positions in a particular group of securities with a similar risk profile or in a particular asset type, thus allowing NSCC to produce margin levels commensurate with the risks and particular attributes of each relevant product, portfolio, and market. Therefore, NSCC believes this proposed change is consistent with Rule 17Ad-22(e)(6)(i) under the Act.[30] NSCC also believes the proposed changes to move TIPS haircuts into a separate category and raise the haircut levels for TIPS would help ensure that the haircut levels for TIPS would be commensurate with the particular risk attributes of TIPS. NSCC has determined that in periods where the inflation rate fluctuates, the current haircut levels for TIPS may be inadequate to address the fluctuations from time to time, and more conservative haircuts for TIPS are warranted. Ensuring that the haircut levels for TIPS are commensurate with the particular risk attributes of TIPS would allow NSCC to produce margin levels commensurate with the risks and particular attributes of each relevant product, portfolio, and market. Therefore, NSCC believes this proposed change is consistent with Rule 17Ad-22(e)(6)(i) under the Act.[31] Rule 17Ad-22(e)(6)(v) under the Act [32]
                    
                     requires a covered clearing agency to establish, implement, maintain and enforce written policies and procedures reasonably designed to cover, if the covered clearing agency provides central counterparty services, its credit exposures to its participants by establishing a risk-based margin system that, at a minimum, uses an appropriate method for measuring credit exposure that accounts for relevant product risk factors and portfolio effects across products. NSCC believes that the proposed changes to move the collateral haircuts and concentration limits from the Rules to the website would provide NSCC with more flexibility to respond to changing market conditions more promptly because NSCC would be able to make appropriate adjustments to the haircuts and concentration limits without a rule change. Having this additional flexibility would enable NSCC to better risk manage its credit exposure to its members because NSCC would then be able to make appropriate and timely adjustments to the haircuts and concentration limits, as described above. Being able to adjust the haircuts and concentration limits appropriately and timely would allow NSCC to better risk manage its credit exposure to its members by (i) collecting sufficient margin from members to cover the risk exposures that NSCC may face in liquidating members' portfolios and (ii) minimizing exposures from members with large collateral positions in a particular group of securities with a similar risk profile or in a particular asset type, thus producing margin levels commensurate with relevant product risk factors and portfolio effects across products. Therefore, NSCC believes this proposed change is consistent with Rule 17Ad-22(e)(6)(v) under the Act.[33] NSCC also believes the proposed changes to move TIPS haircuts into a separate category and raise the haircut levels for TIPS would help ensure that the haircut levels for TIPS would be commensurate with the particular risk attributes of TIPS. Specifically, as proposed, NSCC would have collateral haircuts that are commensurate with the particular risk attributes of TIPS. Ensuring that the haircut levels for TIPS are commensurate with the particular risk attributes of TIPS would allow NSCC to produce margin levels commensurate with relevant product risk factors and portfolio effects across products. Therefore, NSCC believes this proposed change is consistent with Rule 17Ad-22(e)(6)(v) under the Act.[34] (B) Clearing Agency's Statement on Burden on Competition Section 17A(b)(3)(I) of the Act requires that the rules of NSCC do not impose any burden on competition not necessary or appropriate in furtherance of the purposes of the Act.[35]
                    
                     NSCC does not believe the proposed rule changes to move the haircuts and concentration limits from the Rules to the website would impose a burden on competition. These proposed changes are designed to enable NSCC to timely respond to increases in market volatility with haircut requirements and concentration limits that are more reflective of the current credit exposures to NSCC. As discussed above, these proposed changes would allow NSCC to better risk manage its credit exposure to its members by (i) collecting sufficient margin from members to cover the risk exposures that NSCC may face in liquidating members' portfolios and (ii) minimizing exposures from members with large collateral positions in a particular group of securities with a similar risk profile or in a particular asset type, such that, in the event of a member default, NSCC's operations would not be disrupted, and non-defaulting members would not be exposed to losses they cannot anticipate or control. These proposed changes would not unfairly inhibit access to NSCC's services, or disadvantage or favor any particular member in relationship to another member. The proposed changes would allow NSCC to adjust the haircuts and concentration limits more promptly and would not otherwise affect members' access to NSCC's services. In addition, any changes to the haircuts or concentration limits would be directly related to the perceived risk related to members' collateral based on back-tests, stress-tests and market observations, and 
                    ( print page 68783)
                    would be applied uniformly to all members. Accordingly, NSCC believes that these proposed changes would not impose any burden or have any impact on competition. Similarly, NSCC does not believe the proposed rule changes to move TIPS haircuts into a separate category would impose a burden on competition. These proposed changes are designed to improve the clarity and presentation of the haircut information. These proposed changes would not unfairly inhibit access to NSCC's services, or disadvantage or favor any particular member in relationship to another member, and the changes would be applied uniformly to all members. Accordingly, NSCC believes that these proposed changes would not impose any burden or have any impact on competition. NSCC believes the proposed changes to raise certain TIPS haircut levels may have an impact on competition because these changes could result in members' Eligible Clearing Fund Securities being subject to higher haircuts than they would have been under the current haircut schedule. NSCC believes that the proposed change could burden competition by potentially increasing these members' operating costs by requiring members who are using TIPS as collateral to pledge additional collateral. Nonetheless, NSCC believes any burden on competition imposed by the proposed changes would not be significant and, regardless of whether such burden on competition could be deemed significant, would be necessary and appropriate, as permitted by Section 17A(b)(3)(I) of the Act for the reasons described in this filing and further below.[36] NSCC believes any burden on competition presented by the proposed changes to the TIPS haircut levels would not be significant. As discussed above, if the proposed changes to the TIPS haircut levels had been in place during the Impact Study period, two members would have been impacted with an daily average dollar increase of approximately $123,000 (or 0.10% of their average Clearing Fund deposit) and $74,000 (or 0.31% of their average Clearing Fund deposit), respectively. In addition, NSCC believes that the proposed changes to the TIPS haircut levels are comparable with what is being required of users of other similar registered clearing agencies and foreign CCPs when posting TIPS as collateral. NSCC believes any burden on competition that may be imposed by the proposed changes to the TIPS haircut levels would be necessary because, as described above, the proposed changes would help ensure that the collateral values attributed to TIPS would be commensurate with the particular risk attributes of TIPS. Making sure proper collateral values are attributed to TIPS that are used as margin would thus help better ensure that NSCC collects sufficient margin from members and thereby assure the safeguarding of securities and funds which are in the custody and control of NSCC or for which it is responsible, consistent with Section 17A(b)(3)(F) of the Act.[37] In addition, NSCC believes the proposed changes to the TIPS haircut levels are necessary to support NSCC's compliance with Rules 17Ad-22(e)(4)(i), (e)(5), (e)(6)(i), and (e)(6)(v) under the Act. Specifically, as described above, NSCC believes these proposed changes would ensure that the haircut levels for TIPS are commensurate with the particular risk attributes of TIPS. Having haircut levels for TIPS that are commensurate with the particular risk attributes of TIPS would ensure proper collateral valuation for TIPS used as margin. Ensuring proper collateral valuation for TIPS used as margin would help NSCC better measure, monitor, and manage its credit exposures to participants and those exposures arising from its payment, clearing, and settlement processes, consistent with the requirements of Rule 17Ad-22(e)(4)(i) under the Act.[38]
                    
                     Ensuring proper collateral valuation for TIPS used as margin would also allow NSCC to set and enforce appropriately conservative collateral haircuts, consistent with the requirements of Rule 17Ad-22(e)(5) under the Act.[39]
                    
                     It would also help NSCC cover its credit exposures to its participants, consistent with the requirements of Rules 17Ad-22(e)(6)(i) and (e)(6)(v) under the Act.[40] NSCC also believes that any burden on competition that may be imposed by the proposed changes to the TIPS haircut levels would be appropriate in furtherance of the Act because these proposed changes have been specifically designed to assure the safeguarding of securities and funds which are in the custody and control of NSCC or for which it is responsible, as required by Section 17A(b)(3)(F) of the Act.[41]
                    
                     As described above, NSCC believes these proposed changes would help better ensure that NSCC collects sufficient margin from members, thus enabling NSCC to produce margin levels more commensurate with the risks it faces as a central counterparty. Accordingly, NSCC believes these proposed changes are appropriately designed to meet its risk management goals and regulatory obligations. NSCC does not believe the proposed clarifying changes to the Rules would impact competition. These changes would help to ensure that the Rules remain clear. In addition, the changes would facilitate members' understanding of the Rules and their obligations thereunder. These changes would not affect NSCC's operations or the rights and obligations of the membership. As such, NSCC believes the proposed clarifying changes would not have any impact on competition. (C) Clearing Agency's Statement on Comments on the Proposed Rule Change Received From Members, Participants, or Others NSCC has not received or solicited any written comments relating to this proposal.
