Appendix 6-C

Exchange Codes — ISO 10383 Market Identifier Code (MIC)

As of FIX 4.3, Exchange Codes used in FIX are those defined in ISO 10383 standard: Market Identifier Code (MIC). The cross-reference list below is a subset of ISO 10383 values as of the time of this publication. It is provided to facilitate the transition from the Reuters exchange suffix codes which versions of FIX prior to FIX 4.2 were based upon. The official standard and set of values are maintained by the ISO 10383 standard and any discrepancies below should be considered typographical errors using the ISO 10383 standard as the correct set of values. These values are maintained by ISO 10383 secretariat (see Appendix 6-B) and as of the time of this publication the website link to view current list of MIC values is: http://www.iso15022.org/MIC/homepageMIC.htm

Note that "Old FIX 4.2" values which are underlined represent "numeric codes" assigned by the FIX organization in lieu of a valid Reuters exchange suffix. Such values which have a valid MIC value should use the MIC value. Markets without a MIC value should apply to the ISO 10383 Registration Authority (SWIFT) for an appropriate value. The FIX organization will maintain numeric values for required market identifiers which are unable to establish a MIC value for some reason.

Disclaimer: Please refer to the current ISO 10383 standard for the complete list. The following list is a subset and designed primarily to support cross-referencing mapping from FIX versions <= 4.2 to FIX versions >= 4.3 (when the FIX specification standard changed from Reuters exchange suffix to ISO 10383 MIC code).

MIC STANDARD CROSS_REF TO FIX 4.2 20010501 Errata:

Note: XASE, XJAS, XKOR, XMOO, XPSE, and XTAI had more than one value in FIX 4.2, however, have a single MIC identifier.

DEFINED IN FIX 4.2 20010501 Errata BUT UNIDENTIFIED IN MIC STANDARD:

--- Use the "old" or custom FIX value until the exchange/market is assigned a MIC identifier by ISO ---

DEFINED POST-FIX 4.2 20010501 Errata BUT UNIDENTIFIED IN MIC STANDARD:

--- Use the "old" or custom FIX value until the exchange/market is assigned a MIC identifier by ISO ---
