32 2 CLASSES AND S 2.1 Interface Communication T2S actors send or receive Communication to/from T2S through the T2S Interface. Communication is a collective term for messages and files. They have to comply with the formats and specifications defined in T2S {T2S }, {T2S }. Files may contain several messages. A message contains different business data to be processed by T2S. All T2S communication functionalities are available by using messages as well as online screen based activities (Graphical User Interface) {T2S }, {T2S }, {T2S }, {T2S }, {T2S }, i.e. T2S can be accessed in application-to-application mode (A2A) to allow direct communication between software applications via XML messages. For the T2S communication via messages the ISO 20022/UNIFI is the single standard, both inbound and outbound. In addition, the use of ISO complies with Giovannini protocol recommendations for both inbound and outbound communication {T2S }, {T2S } and in user-toapplication mode (U2A) concerning activities performed manually by T2S system users via Graphical User Interface {T2S }. Header Information Entry Timestamp Input Channel Status Status Description Header information of the received communication e g Sender BIC Point in time when the communication was received by T2S Identifier for the channel that was used for communication e g Network provider dedicated line etc Status of the processing on communication level Additional status information e g error code Message Messages can be sent as single messages or as content of a file. A message contains different business data to be processed by T2S (bulk message or single settlement instruction, query request, static data change request, liquidity transfer order, etc.). Technical validations regarding the specific structure, format and syntax of messages are executed.

33 Entry Date/Time Message Type XML Message Content Status Status Description Point in time of the last update Type of message received Actual XML message content Status of the processing on message level Additional status information e g error code Task Tasks are T2S operations where a 4-eye principle is applicable (due to the T2S system user s role or the activity itself). They are stored as dynamic data directly after the entry of the related message to trace there status. Each task gets a unique Task ID. The business data of the task and the Task ID are delivered to the subsequent module. The related subsequent module executes business validations and processes the business data, but without completing it. The related subsequent module sends a response to the Interface which includes the result of the business validation, the Task ID and, if needed, the reference of the subsequent module. In case of a negative result the task based on an incoming message is rejected. a positive result a second authorised T2S system user has to confirm or cancel the task. A received confirmation message is linked to the original request (Task ID). Then the confirmation including the Task ID and, if needed, the reference of the subsequent module is forwarded to the subsequent module. A received cancellation message is linked to the original request (Task ID) which is rejected afterwards in coordination with the subsequent module. Related to the T2S system user s privileges the status of task processing is displayed in U2A mode. T2S system user related tasks can also be requested in A2A mode. Task Status Status of the processing on Task level

34 2.2 LCMM Action Information extracted from a message. A validated action allows to create an Individual Settlement Instruction. Every message received is converted into one or several actions (one physical registry into several logical registries) in order to start the validation process to each of those logical actions. Each Action is linked to its relevant Settlement Related Instruction to which it belongs on the one hand and, on the other hand, to their Action Parameters that that tells what to do. Each Action is also linked to: Validation error in case the validation process done to the Action finds an error. Individual Settlement Instruction in case the validation process done to the Action is ok. This double link is mutually exclusive to each other. If the link exist to Validation Error, it doesn t exist to Individual Settlement Instruction and vice versa. Action Type Status Possible values - Creation - Hold - Release - Cancel - Amend - CoSD Release - CoSD Cancel Possible Values -Rejected -Accepted -Executed - Cancelled Action Error Information about the errors that occurred during the validation of a settlement Instruction Each Validation Error is linked to its relevant Action and to its relevant Error Description.

38 Command Possible Values -Hold -Release Individual Settlement Instruction This entity includes the specific information of one instructing leg of the Instruction except the information regarding the movements of the instruction (securities and cash). The detailed information of the instruction may change in time, but only one Individual Settlement Instruction is present at any given point in time. Each Individual Settlement Instruction must be linked to the only one Settlement Related Instruction that caused the creation of itself. Each Individual Settlement Instruction is linked necessarily to ISI Status for maintaining the last statement of its different statuses, to its relevant Half Securities Movement and Half Cash Movement (in case it is needed), and it is also linked to its relevant Action. In case it is needed, depending on the different situations, the Individual Settlement Instruction is linked to ISI Link, CoSD Party, Hold/Release Party and Allegement. Finally, each Individual Settlement Instruction is linked to the Settlement Transaction to which it is part.

This entity includes all the common information that is shared in any instruction. Since a Settlement related Instruction is received for the purpose of doing something related to settlement instructions, each Settlement related Instruction is linked at least to one Action. Since this information is only part of the whole information received in relation with the settlement instruction, this entity is also linked to the «Individual Settlement Instruction» when this one is created. This situation only occurs when the type is settlement Instruction and the status is Accepted. Otherwise, this link doesn t exist.

Since T2S is technically capable of providing cash settlement in noneuro central bank money, liquidity transfers are possible in all T2S settlement currencies. {T2S } As far as credited and debited accounts are denominated in the same currency {T2S , T2S , T2S }, liquidity transfers are possible under the following conditions between a T2S dedicated cash account and any RTGS account and vice versa provided this is allowed by the relevant NCB(s) between two T2S dedicated cash accounts linked to the same RTGS account or between two T2S dedicated cash accounts belonging to the same payment bank (i.e. proprietary and clients accounts) between a T2S dedicated cash account of an account holder and the T2S dedicated cash account/t2s NCB account of an NCB As a general rule, a liquidity transfer from an RTGS system to T2S is initiated in the RTGS system; a liquidity transfer from T2S to an RTGS system is initiated in T2S. In any case, liquidity transfers in T2S are executed real-time (except during the night-time settlement when a settlement cycle is running) {T2S }. Transfer Type Possible values are Immediate liquidity transfer order Predefined liquidity transfer order Standing liquidity transfer order Notification

A T2S System User can query historical data for a period of the last 90 business days. Generally, all User Queries are processed in real time, based on the latest available data {T2S }. When processing queries all privileges as defined in Static Data are taken into account {T2S } The response to a User Query always contains the timestamp that specifies the T2S system time when the data selection was actually performed. {T2S }

46 Criteria Set Name Remarks Name of the filter criteria as given by the user Additional field for remarks Query Name Name of the type of user query this filter criteria belongs to e g Securities Settlement Instruction Query Query Filter Criteria Entry According to the various query types, different fields can be used as selection criteria. These selection criteria can be combined with a relation and/or a value. Field Name Field name of a selection criteria to filter the query result The available fields can be found in the Appendix A depending on the different query types Relation comparison operator </<=/=/>=/>/<> Value fixed value for comparison Report T2S provides T2S actors with a number of pre-defined reports for periodical information on the production data. The Report Management Module, however, does not cover any regulatory reporting. The reports provided are set up as XML messages and comply to the largest possible extent with ISO standard. In cases where the standard is not able to meet T2S demands, proprietary messages are defined {T2S }. All reports are available in user-to-application mode and in application-to-application mode {T2S }. All securities instructions, balance and static data reports are available for all CSDs in T2S, T2S parties and NCBs {T2S }. Reports can be sent to CSDs and directly connected T2S parties, containing information on one or several accounts {T2S }. T2S reports can either be sent on a business event (e.g. end-of-day) or on a time event (i.e. at a fixed time) {T2S }. If a report got lost, it can be downloaded again by the affected T2S actor. Furthermore, in case a report is incorrect, e.g. due to technical problems, the report of a specific day can be regenerated by a NCB system administrator via a Report Generation Request.

47 Report Name Report Data Report Timestamp Name of the stored report - possible values are Statement of Holdings Statement of Transactions Statement of Pending Instructions Statement of Settlement Allegements Statement of End-of-Day Balance Statement of Static Data Billing Data Report Current Settlement Day Cash Information Report Following Settlement Day Cash Forecast Report Report content stored as flat file Timestamp reflecting date and time of the creation of the report 2.6 Rules and Parameters Allowed Instructing Party This entity stores the combination of instruction types and instructing party types that T2S will allow for processing for the specified restriction. Market-specific restriction types (T2S ) An objective of T2S and of many market participants is to achieve harmonised securities account structures. Nevertheless, the requirement currently exists to provide account structures that support segregation, blocking, reservation and earmarking of securities positions in a variety of existing models in the various markets. Furthermore, T2S must also support the blocking of T2S parties, securities accounts and dedicated cash accounts based on the regulatory and legal requirements of a country. To support the aforementioned, T2S will allow CSDs to define their own restriction types. Restriction types are attributes that define the specific processing characteristics for a securities position, a securities account, a T2S dedicated cash account, a party or a cash amount as to ensure configurability of market-specific requirements, as prescribed by legal and regulatory requirements and practices.

58 Valid From It specifies the date from which the rule set is valid Operating Day Event Schedule Time Updated Event Schedule Time Event Start Time Event End Time Scheduled time for each Event Scheduled time for each Event following an update Actual start time of the Event Actual end time of the Event Operating Day Type This entity includes all the information concerning the operating day types defined in T2S. Each operating day type is linked to all the event types foreseen for the operating day type itself. Operating Day Type Code Operating Day Type Description Code of the operating day type Description of the operating day type Partial Settlement Threshold This entity includes all reference data related to partial settlement thresholds defined in T2S {T2S }{T2S }. Each partial settlement threshold is linked to its relevant party (i.e. CSD, CCP or the T2S Operator) or to its relevant securities account {T2S }{T2S }.

59 Threshold Type Amount Type Threshold Value It specifies a classification for the threshold Possible values are 1 Cash 2 Nominal 3 Number of shares It specifies a classification for the threshold value Possible values are 1 Absolute value 2 Percentage Value of the threshold Partial Settlement Threshold Group Partial settlement thresholds (T2S ) T2S shall specify the harmonised threshold setting for partial settlement on the level of T2S operator. The setting on T2S operator level shall apply for all CSDs, CCPs and participant accounts, when the aforementioned allow partial settlement, but have no thresholds configured. It shall also apply for Cross-CSD settlement in T2S. T2S shall allow each CSD and each CCP to define its own internal thresholds for partial settlement. A CCP threshold shall prevail over the CSD and Cross-CSD thresholds. Valid From Party Type Party or Account Identifier This attribute shall specify the date from which the threshold is valid This attribute shall define whether the threshold applies to the T2S operator CCP CSD or participant account This attribute shall specify the unique technical party identifier of the T2S operator a CCP or a CSD if the party type specifies one of the aforementioned Otherwise it shall specify a specific account identifier in T2S Privilege This entity includes all reference data for privileges {T2S }. Each privilege can be linked to one or many privilege classes and roles. Each privilege can be directly linked to many users.

60 Privilege Name Privilege Description Name of the privilege Description of the privilege Privilege Class This entity includes all reference data for privilege classes Each privilege class can be linked to one or many roles and privileges {T2S }. Privilege Class Name Privilege Name of the privilege class Description of the privilege class Privilege Link Privilege Link is a many to many relationship between Privilege and Privilege Class entities. When linking a Privilege to a Privilege Class, a Role or a User, a boolean attribute specifies if the privilege is denied or granted to the relevant Privilege Class, Role or User Deny Administration Option GFS Boolean attribute specifying whether the grantee of the privilege can grant the same privilege to another user or not Reference Value This entity includes all reference data for reference values. Each reference value is linked to the relevant attribute reference and attribute value.

61 Reference Value Reference Value Description Value of the attribute reference Description of the reference value Role This entity includes all reference data for roles Each role can be linked to one or many privilege and privilege classes. Moreover, each role can be linked to many users {T2S }. Role Name Role Description Name of the role Description of the role Role Privilege Privilege Link is a many to many relationship between Privilege and Role entities. Deny If the Deny Flag is set to TRUE the privilege is not allowed even if it is present in a privilege class assigned to the Role Roles T2S A role is the set of functions and services to which the authorization application allows or denies the user access A role consists of one or more privilege classes or privileges When a T2S system administrator assigns a privilege class to a role the T2S system administrator shall specify if the privilege within the class allows or denies access to the functionality defined by the privilege Administration Option GFS Boolean attribute specifying whether the grantee of the privilege can grant the same privilege to another user or not

62 Role Privilege Class General Functional Specifications Privilege Link is a many to many relationship between Privilege Class and Role entities SAAP User Securities Account Access Privilege This entity includes all reference data related to access privileges that limit the access of the party s T2S system users to specific securities accounts of the party {T2S }. Valid From Privilege Name Privilege Text Description It specifies the date from which the securities account access privilege is valid Name of the securities account access privilege Textual description of the securities account access privilege Sequencing Rules This entity includes all the information needed to determine the sequence for processing of settlement instructions {T2S }. Each sequencing rule is linked to the relevant (sender) party type, instruction type and transaction type.
