Overview

This document applies to all releases of Eagle software V11 and above. It covers the full lifecycle including Accounting, Data Management, and Performance. Version-dependent functionality is noted with the initial release(s) it became available.

Inflation-Linked Swaps (ILSs) allow one party to make fixed or floating interest payments to a counterparty in exchange for payments based on the level of inflation. This is benchmarked against a measure of inflation, such as the Consumer Price Index (CPI). While there are various flavors of ILSs, including bespoke agreements, most are Zero Coupon Inflation Swaps (ZCISs). This means there is a single bullet payment at maturity, rather than periodic payments throughout the life of the contract. ZCISs are the focus of this document. For ILS contracts where the inflation leg mimics an underlying Inflation-Linked Bond (ILB), refer to Inflation-Linked Asset Swaps (ILAS) Best Practices.

Eagle Accounting supports both bilateral and cleared ZCISs in V12.1.2 and above. This document focuses on bilateral contracts. Refer to Cleared Swaps Best Practices for more information on processing cleared IRSs, which function identically to ZCISs in terms of variation margin (VM) processing. The main difference is for an ZCIS is you will only have one or two VM records each day (contract and potentially one leg) vs. three VM records for an IRS (contract and both legs). This is described further in the Valuation section.

Reference Data

Storage & Configuration

Eagle

has modeled ZCISs

models TRS security master files (SMFs) as three rows in Data Management, each with its own Security Alias (10), linked by a common Primary Asset ID (14).

 Eagle

 Eagle Accounting must be set up to allow duplicate IDs for swaps by following the steps

here:  Include PageMulti-Leg SWAPIDs Processing Notes

 for information about the unique SWAPID identifiers that are automatically created for the contract and each leg of a multi-leg swap.

Market Data

ZCISs are typically priced dirty in the market. To prevent any double-counting during valuation, inflation income must be turned off in Eagle Accounting. This is accomplished by setting both legs to be interest accrual legs, rather than one inflation leg and one interest accrual leg. As a result, you do not need to load any inflation index values for this security.

The interest accrual leg of an ZCIS uses either a fixed or floating rate. If you are using an all-in dirty price (inclusive of both inflation and interest), accruals should be turned off for both legs

should be up with

. This can be done by setting a fixed rate

coupons

coupon of zero or using Debt Default Periods as described in https://eagledocs.atlassian.net/wiki/pages/createpage.action?spaceKey=Accounting2017&title=About%20Default%20Bond%20Processing. If you are using a dirty price that only includes inflation, you can accrue the fixed or floating interest in Eagle Accounting. For floating legs, the underlying floating rate index must be set up using Issue Viewer, Security Reference Manager (SRM), or Reference Data Center (RDC). Other than identifiers, the only required information is the currency.

Once the index has been setup, floating rates can be loaded using Add Variable Rate. Eagle Accounting will automatically pull the appropriate rates into the accrual process based on the floating leg's First Rate Reset Date (10911), Reset Frequency (1788), and Reset Look-Back Days (10547).

  • Interest rates must be loaded to the underlying index back to Dated Date (or previous coupon date if swap is traded off-cycle) and each subsequent coupon date minus Reset Look-Back Days

Security Data

ZCISs can be set up and maintained in Issue Viewer, SRM, or RDC. Most data is entered on the contract and propagated to the legs. Specific reset and accrual conventions are entered separately on each leg.

Contract

  • Issue Name (961)

  • Primary Asset ID (14) & Type (1432): ensure duplicate IDs are allowed (see Storage &

Configuration section
  • Configuration section above)

  • Processing Security Type (3931) = SWCOIF (Inflation Linked Swap Contract)

  • Price Multiplier (18): the default of 0.01 will be correct in most cases, but may need to be changed to 1.00 (ZCIS prices are sometimes supplied having already been multiplied by 0.01)

  • Issue Country (1418)

  • Asset Currency (85)

  • Cleared Security (5027): cleared ZCIS are supported (refer to Cleared Swaps Best Practices for information on the VM process)

    • If you are using an all-in dirty price, you will have a single VM record for the contract each day

    • If you are accruing interest in Eagle and using a dirty price that only includes inflation, you will have two VM records each day: one each for the contract and interest accrual leg

  • Issue Date (68): first trade date of the swap

  • Dated Date (1183): date accruals start, "Effective Date" in ISDA contracts

  • Maturity Date (38): date swap expires, "Expiration Date" or "Termination Date" in ISDA contracts

Legs

The "Interest Leg" values should only be used if you are accruing in Eagle or are using Debt Default Periods to suppress accruals (as described in https://eagledocs.atlassian.net/wiki/pages/createpage.action?spaceKey=Accounting2017&title=About%20Default%20Bond%20Processing), otherwise both legs should use the "Inflation Leg" values

)

. An overlay can be applied to Create Security Debt Default Periods Automatically during security creation.

  • Processing Security Type (3931) = SWLEAC (Swap Leg Interest Accrual)

    • This should be used for both legs

    • Do not use SWLEIF (Swap Leg Inflation Linked Interest Accrual)

  • Coupon (70)

    • Inflation Leg: 0

    • Interest Leg: enter stated rate for fixed leg and zero for floating/variable rate legs to indicate that actual rates must be viewed from VARIABLE_RATE table

      • The following fields are conditionally required if Business Day Convention != NULL or NONE

        • Coupon Day of Month (10551): day of the month that payments are scheduled to be made, which will be automatically adjusted based on the Business Day Convention

        • Business Calendar (1480): as specified in the contract; a composite calendar (including dates from two different calendars) may need to be setup in some cases

  • First (473) & Last Payment Date (474)

    • Inflation Leg: set to Maturity Date

    • Interest Leg

      • Set to Maturity Date if Payment Frequency = MAT (At Maturity)

      • For any other Payment Frequency, set to actual first and last payment dates, including any adjustments for weekends/holidays

  • Floating Rate Fields (only applicable to the Interest Leg

)
  • First Rate Reset Date (10911): enter the actual first reset date, including any adjustments for weekends/holidays (same as First Payment Date unless the rate resets more frequently)
  • Reset Frequency (1788): same as Payment Frequency unless the rate resets more frequently
  • Reset Look-Back Days (10547): number of days prior to reset date to take new floating rate
  • Reset Look-Back Days Type (5075): whether reset look-back days are measured in business or calendar days
  • Fixing Date Business Center (16407, V15 R2.18): select calendar used for floating rate resets, which may be different than the calendar used for payment dates; this calendar will be used in lieu of the main Business Calendar when applying the Reset Look-Back Days for fixing dates
  • Underlying Security (1347): select appropriate floating rate index security
    • This can be used to store the Inflation Leg's benchmark index for reference and reporting purposes, but it is hidden in the core panel
  • Spread/Index Offset (215): spread above or below the floating rate, entered in basis points (0.55% = 55)
    • When a floating rate (0.25%) plus negative spread (-55 bps) goes negative (effective rate = -0.3%), accruals and coupons are posted in the appropriate direction

Trade Processing

Open (transaction type: OPENSWAP)

Trades are entered using the Book Trade module once the entity and reference data have been configured. Enter the appropriate entity, security identifier, and trade (35)/settle (37) dates and click Submit to query for the security. Right-click it and select Open > Open Swap Contract. Most remaining trade information is entered on the contract, with the exception of a few accrual-related fields on the legs.

Contract

  • Traded Interest/Effective Date (2857): date to which traded interest is calculated; typically Trade Date or T+1
    • ZCIS sometimes have Trade Date = Settlement Date, where Traded Interest/Effective Date needs to be T+1 to calculate correct traded interest and accruals
    • This can be ignored if you are not accruing in Eagle Accounting
  • Select Values to be Calculated by STAR (7000)
    • Traded Interest: Eagle Accounting will calculate and create cash records for traded interest (only applicable for off-market trades)
    • Calculate None: traded interest can be entered manually
    • This can be ignored if you are not accruing in Eagle Accounting
  • Data Entry Method (10485): select Enter Price to supply a unit price or Enter Total Settlement Amount to supply the all-inclusive trade proceeds (both can be positive or negative)
    • Enter Price: for the contract and each leg, cost (Principal) is calculated as Notional Principal Value * Price * Price Multiplier and Net Amount = Principal + Traded Interest
      • This price should be dirty in the same way as the end-of-day prices
      • The legs of an ZCIS have no cost
    • Enter Total Settlement Amount: cost (Principal) is calculated as Total Settlement Amount - Traded Interest and Net Amount = Total Settlement Amount
    • Depending on the type of trade (open or close) and sign of the Price or Total Settlement Amount, Eagle Accounting will post either a premium payment or premium receipt
      • Open @ Positive Price/Amount ---> Premium Payment
      • Open @ Negative Price/Amount ---> Premium Receipt
      • Close @ Positive Price/Amount ---> Premium Receipt
      • Close @ Negative Price/Amount ---> Premium Payment
  • Notional Principal Value (40): enter value specified in contract
  • Price (45, if applicable): enter par-zero price (around zero)
    • Par-100 prices (around 100) must be converted to par-zero in order to have Eagle Accounting calculate the correct cost and cash
  • Total Settlement Amount (4404, if applicable): enter all-inclusive trade proceeds, including the effect of traded interest
  • Broker (88)
  • Counterparty (1144, optional): the counterparty can be selected from a list of all Issuers that have been tagged as counterparties (see Setting Up Legal Entities Best Practices for more information)

Legs

  • Lot Level Dated Date (4411, optional): for swaps traded in multiple lots, this field specifies the date from which traded interest will be calculated for each lot (the contract's dated date if null)
    • To have Eagle Accounting calculate zero traded interest, set this field equal to Traded Interest/Effective Date
    • This can be ignored if you are not accruing in Eagle Accounting
  • First Period Coupon Rate (1360, floating rate legs only, optional): for swaps traded in multiple lots, this field can be used to override the floating rate for the first accrual period (Eagle Accounting will start using the floating rate index after the first reset is processed)
    • This can be ignored if you are not accruing in Eagle Accounting

Close (transaction type: CLOSESWAP)

The Book Trade module should also be used to process both full and partial terminations. Enter the same identifiers as the open to query for the security. Right-click it and select Close > Close Swap Contract. Like the open, most information is entered on the contract. Almost all fields on the close are the same as the open.

  • Lot Selection Method (27): ZCIS can be closed using either FIFO or IDLOT
    • If Lot Level Dated Date is used to override the initial rate and a FIFO close is booked before the next reset, traded interest calculated by Eagle Accounting may be incorrect because it will be based on the SMF attributes
      • In these cases, traded interest can be entered instead of calculated
      • This can be ignored if you are note accruing in Eagle Accounting
  • Accrual End Date (4412): defaults to Settlement Date, which results in Traded Interest through Settlement Date - 1 (similar to a bond)
  • To calculate through Trade Date (typical for ), populate with T+1
  • This

    Trade Processing

    Open and close trades are booked identically to IRSs. The price is entered on the contract and accrued interest, if applicable, is calculated on the appropriate leg. Refer to https://eagledocs.atlassian.net/wiki/spaces/IE/pages/1658978617/Interest+Rate+Swaps+IRS+Best+Practices#Trade-Processing for more information about booking trades. The accrual-related fields can be ignored if you are not accruing in Eagle Accounting.

    Conversion

    The CONVERSION event is supported for ZCISs. This uses the core open swap screen, rather than the dedicated conversion screen.

    Cancel & Rebook

    Faulty transactions must be cancelled using Batch Cancel Trades, with the transaction rebooked using the Book Trade module. ZCISs are not supported in the Cancel & Rebook Trade process. Maturities must also be canceled using Batch Cancel Trades.

    Accounting

    Once an ZCIS trade is booked it will be picked up in Eagle’s global workflow. Daily accruals

    and periodic resets

    (if applicable) are generated as part of the earnings process, Accounting valuation is calculated when posting unrealized gain/loss, and Data Management valuation is calculated in STAR to PACE. These can be scheduled or triggered manually.

    Valuation

    Eagle Accounting values ZCISs using clean unit prices on a par-zero basis (around zero rather than around 100). Prices

    are

    must be entered at the contract level using Add Issue Price or Pricing Center. The market value formula is:

    • Market Value = Notional Amount * Price * Price Multiplier * Quantity Scale

      • If you are using an all-in dirty price (inclusive of both inflation and interest), both legs should be up with fixed rate coupons of zero

      • If you are using a dirty price that only includes inflation, the accrued interest portion of an ZCIS's MV will be captured in its Market Value Income (MVI)

    Accruing on Negative Interest Rates

    This can be ignored if you are not accruing in Eagle Accounting.

    Include Page
    Journal Entries for Negative Interest Rate Accruals Processing Notes

    Mature/Expire

    ZCISs will be picked up by Eagle Accounting’s core maturity process. This will be scheduled in production environments, but can be triggered manually via Accounting Center > Processing and Exceptions > Global Processes > Expirations & Maturities > Run Mature Process (V17) or Global Process Center > Expirations > Mature (prior to V17).

    There is no cash component to the maturity event itself because swaps have a Maturity Price of zero and final coupon payments are dropped as part of the accrual process.

    Reporting

    STAR to PACE (S2P)

    Almost all reports in Eagle Accounting leverage data from Data Management, which is populated by the S2P process. This will be scheduled as part of the daily workflow, but can also be triggered manually as described in the Accounting section.

    The S2P process creates three rows for each ZCIS in the POSITION, POSITION_DETAIL, TRADE, and CASH_ACTIVITY tables. The MARKET_VALUE_INCOME column for each row captures a portion of the total market value.

    • Contract

    Position
    • : market value due to price fluctuations

    • Pay

    Leg Position
    • & Receive Legs: market value due to period-to-date accruals payable

  • Receive Leg Position: market value due to period-to-date accruals receivable
    • For an ZCIS, the pay leg and/or receive leg will be zero (both if you use an all-in dirty price)

    Accounting Reports

    Eagle has a core set of accounting reports that can be used to review ZCIS and other security information. These are designed to support the daily operational workflow for business users, allowing Grid Reports to be easily exported to Excel and customized to provide additional details as needed. Advanced Reports are intended to be client-facing and do not provide the same level of customization.

    ZCISs are displayed as three separate rows. The contract and legs are intended to be displayed together, but may be broken into different areas depending on the report's groupings (long/short, for example).

    Performance

    The performance toolkit calculates market value-based performance for ZCISs at the contract (price changes) and leg (accruals paid/received, if applicable) levels using data supplied by the S2P process. However, this can be misleading because swaps use notional values and typically start with a market value of zero. Exposure-based analyses, which can be implemented using Eagle Enrichment, calculate more

    accurate

    meaningful returns. Please contact Instrument Engineering if you are interested in these analyses for ZCISs.
