X9 Subcommittees and Work Groups

X9 Board of Directors

The X9 Board of Directors makes the final decisions on new work efforts to develop standards and makes the ultimate decision on approval of standards. Thus, the Board of Directors acts as the Consensus Body within X9. This group also acts as the U.S. Technical Advisory Group (TAG) to ISO TC68, ISO TC322 and ISO TC321 for international standards. Subcommittees with experts mirroring important business sectors of the financial services industry report to the Board of Directors. Under these broad business areas of the Subcommittees, additional experts are organized into Work Groups. The Board also forms management committees that serve X9.

The parts of this standard, including the normative annexes, establish a Mark Preamble, the location and printing restrictions, the message structures, file layouts, record types, and field formats to be used for the electronic exchange of information necessary to perform verification of image-survivable check security features in an interoperable manner.

X9B18 Automated Check Adjustments Work Group

X9B18 was formed to create a standard to provide the financial industry with a format to perform electronic exchange of check adjustments. The format supports all adjustment requests, adjustment notices, and other related messages. The intent is to establish a file format that can be used by any system where an adjustment file can be sent to automate transmission. Members include financial institutions and vendors.

X9B20 International Bank Account Number (IBAN) Work Group

X9B20 was formed to reply to the international standards ISO 13569 (IBAN), U.S. financial institutions lack a standard International Bank Account Number (IBAN) for use with their trading partners outside the United States. The US IBAN will clarify routing instructions for transactions and help eliminate routing errors and delays. Mandated in EU countries, the International Standard ISO 13569, specifies the elements of an international bank account number (IBAN), used to facilitate the processing of data in data interchange internationally – in financial environments as well as within and between other industries. The IBAN is designed for automated processing, but can also be used in other media interchange when appropriate. The International Standard does not specify internal procedures, file organization techniques, storage media, languages, etc. to be used in implementation, nor is it designed to facilitate routing messages within a network. It is applicable to the text data conveyed through a system (network).

X9B22 Legal Order Processing Work Group

X9B22 was formed to develop the ANSI X9.129 Legal Order Exchange Standard to provide a format to electronically exchange legal orders between requestors and financial institutions. Working in collaboration, several financial institutions and state agencies have already created and implemented a standard for exchanging requests for information and payment related to levies, child support arrears, and taxes through X9B22 in an electronic file format. This workgroup is also focused on developing a standard for third parties to request financial information pursuant to subpoenas and similar legal requests, as well as the responses of financial institutions.

X9C Corporate Banking Subcommittee

Corporate banking is an umbrella term for treasury, finance, and cash management functions within a corporation and for banking services offered to corporations. Corporate banking is separate from capital-raising, mergers advice or risk mitigation. It’s usually the work-a-day stuff of a corporate treasurer: Moving cash between thousands of separate accounts; handling foreign-currency transactions; financing short-term trade balances; and processing customer payments.

X9C1 Balance Transaction Reporting Specification (formerly BAI’s Cash Management Reporting) Work Group

This former BAI “standard” was legally transferred (the copyright) to X9 and X9 has copyrighted the standard in its own name. The codes contained in the former BAI Cash Management Reporting document are widely used in the area of cash management reporting by banks and corporate. The project will convert the existing codes into a formal cash reporting standard and update all relevant areas. Given the widespread international use of the “BAI codes” the final work product will consider the needs of a broader community including its relevance to ISO 20022. Finer details of the work effort are being prepared in advance of the September 2009 initiation of the revision work effort.
