In order to ensure competitiveness as well as stability and long-term development, ATHEXCLEAR has established, maintains and applies Remuneration Policy, that is complying with its business objectives, without compromising the level of security and maintaining ATHEXClear within standard risk limits.
Specifically, although all remuneration provided by ATHEXCLEAR is fixed, where the company decides to pay variable remuneration, the following rules hold: i) the long-term performance of the ATHEXCLEAR and its employees as well as prospective and existing risks and risk outcomes are taken into account, ii) possible mismatches of performance and risk periods are taken into account, and it is ensured that payments of variable remuneration are deferred as appropriate, iii) as regards the executives of the internal audit, risk management and compliance, variable remuneration does not depend on the business performance of the units they audit, iv) the proportion of fixed and variable remuneration is aligned with risk management, v) non-executive members of the Board of Directors receive only fixed remuneration, under the conditions laid down in ATHEXCLEAR's Articles of Association, in order to avoid conflict of interest. However, where it is deemed necessary to implement mechanisms to provide incentives when determining their remuneration, these mechanisms should be strictly adapted to the duties of those mentioned above as regards monitoring the implementation and revision of the remuneration policy, and to their personal skills and the results achieved, taking into account the institutional and oversight framework of the EMIR. Where financial instruments are given, proper measures must be taken, such as the time they are held is until the end of their term of office, in order to safeguard impartiality in their use, and vi) the fixed and variable components of total remuneration are balanced and are consistent with risk alignment.
Responsible for the prudent management of the Remuneration Policy is the Board's Nomination and Compensation Committee. The Remuneration Policy is subject to independent auditing on an annual basis.

General principles underlying ATHEXClear Risk Models and Methodologies
Initial Margin and Haircut Methodology
ATHEXClear makes use of a parametric Value-at-Risk (VaR) model in order to calculate margin parameters for the securities market and input parameters for the RI.VA. system (SPAN like) used in derivatives market to calculate margins. The estimation of margin parameters is done at 1% significance level. The lookback period is twelve (12) months, while the risk horizon is two (2) to three (3) days for securities and two (2) to four (4) days for derivatives, depending on their expected liquidation period. Moreover, in order to count for pro-cyclicality a stressed period is incorporated, creating a mixed distribution with fatter tailes. Note that for Haircut Parameters the same methodology applies but at a 0.1% significance level. For the Derivatives Market the estimated parameters are incorporated into to a SPAN like model where initial margin is calculated. The input parameters for futures contracts are: (i) Valuation Interval for the underlying and the (ii) Adjustment factor, to count for maturity spreads (calendar spread); whereas for options the input parameters are: (i) Valuation Interval for the underlying instrument, (ii), Central Volatility, (iii) Change of Volatility and (iv) the Risk Free Rate.
For the Securities Market Correlations apply only among high liquid securities which are significantly and stable correlated with a benchmark index (currently only with the ATHEX FTSE/LARGE CAP Index); these securities belong to a correlation group. For securities within the correlation group, their estimated risk parameter is split in two (2) components: a general and a specific risk component, where the general component represents market risk of each security and the specific component their idiosyncratic risk. The general risk parameter is a residual parameter obtained by subtracting the specific risk parameter from the total risk parameter. Note that only securities belonging to the same Clearing Account are allowed to offset their general risk component (i.e. netting of Initial Margin); moreover only securities with opposite position signs (long/short) are allowed to offset their market risk. Initial Margin netting is not allowed in the Derivatives Market; only a maturity spread (calendar spread) among different series with the same underlying instrument apply.
Stress Test Methodology
ATHEXClear is obliged to cover on a daily basis stress test results in terms of loss as well as in terms of liquidity, arising from the default of a certain group(-s) of CM(-s) with the highest stress exposure for each market (securities, derivatives) under extreme but plausible market conditions.
As far as Counterparty Credit Risk is concerned, ATHEXClear is obliged to cover on a daily basis credit stress test results (in terms of P/L) arising from the default of the Clearing Member in which ATHEXClear has the largest risk exposure in terms of stress result (cover 2) or of the 2nd & 3rd Clearing Member if the cumulative risk exposure is higher, taking into account the dependencies of their groups (cover 2). Additionally the default of the 1st & 2nd Clearing Member with the largest cumulative risk exposure including specific own funds (SIG) shall be covered, taking into account the dependencies of their groups (cover 2). The simulated losses are net of total pledged margin collaterals.
As far as Liquidity Risk is concerned, ATHEXClear is obliged to cover on a daily basis liquidity stress test results (in terms of liquidity needs) arising from the default of the 1st & 2nd Clearing Member with the largest cumulative liquidity risk exposure for each market (securities, derivatives) taking into account the dependencies of their groups (cover 2). Liquidity needs airing from close-out of positions in case of a Clearing Member default rise within an upward sloping environment, i.e. liquidity amounts needed for physical delivery of stocks in the securities and derivatives market rise vis-a-vis stock prices. The available liquidity resources of the respective markets are (i) pledged cash collaterals of all CMs, (ii) Specific Own Resources (SIG) and (iii) Default Fund contributions. Moreover ATHEXClear could cover additional liquidity needs with its (iv) own liquidity (cash).
Stress scenarios for Counterparty Credit Risk as well as for Liquidity Risk are historical and hypothetical. In both scenario categories extreme but plausible market conditions are simulated. The main goal is to simulate extreme conditions where prices of diverse instruments move adverse with respect to CA positions as well as to simulate correlation breaks. Currently twelve (12) stress test scenarios are performed on a daily basis. Ten (10) scenarios for testing vulnerability resulting from CCR and two (2) for testing liquidity risk exposure aiming to cover all possible market constellations. Scenarios applied show the losses ATHEXClear would have to cover with own and contributed pre-funded financial resources of Clearing Members according to the default waterfall sequence as well as with own Equity Capital. The stress results are aggregated at Clearing Member Group level.
Nature of Tests Performed
On a regular basis a validation of margin models takes place. Particularly for the margin model a daily Back-testing Procedure at Clearing Account level is performed. Within the back-testing procedure a verification whether the realized price fluctuation (P/L) of positions at Clearing Account level is in line with model predictions, i.e. whether the percentage of outliers given the number of observations are greater than the significance level (α). In evaluating the outcomes a "Traffic Lights Approach" applies. Under this approach back testing results are classified into three zones, (i) Green zone: the results do not suggest a problem with the quality or reliability of the model; (ii) Amber zone: the results give rise to some questions regarding the quality or reliability of the model but firm conclusions can be drawn; and (iii) Red zone: the results almost certainly suggest a problem with the quality or reliability of the model. For Haircut Parameters the same methodology applies but at single asset level (unit back-testing).
Another validation component is the Sensitivity Analysis. According to this, several parameters of the VAR model, i.e. confidence level, correlation assumptions, Implied Volatility and significant drop in prices of cleared instruments issued by Clearing Members are progressively stressed in order to estimate their sensitivity with respect to the change in required margin. Sensitivity analysis results serve as a benchmark whether the calculated margin deviates significantly from the expected shortfall (fat tails) or whether correlation assumptions have a large offsetting effect or portfolio effect.
Reverse Stress Testing is an integral part of the robustness test of the stress framework. The aim is to simulate that market conditions that would exhaust all available financial resources of ATHEXClear before Equity Capital. The outcome serves as a benchmark check for the plausibility of stress scenarios, i.e. whether the plausibility criterion as well as the extremeness of stress scenarios are valid. The approach is to stress market prices for diverse financial instruments or/and to squeeze liquidity progressively until loss absorbing financial resources or available liquidity resources are exhausted.
