On February 15, 2002, the Board published in the Federal Register amendments to Regulation C effective for data collected beginning January 1, 2003, and solicited comment on several related issues with a comment period that closed on April 12. Financial institutions and their trade associations requested a postponement of the effective date until January 1, 2004, on the grounds that a 2003 deadline does not afford institutions adequate time to take the steps necessary to ensure full compliance with the new rules (including reprogramming their data systems and retraining their employees). Consumer and community organizations generally opposed postponement of the effective date. The Board has weighed the financial institutions' claims and underlying assumptions against public policy benefits of collecting the new data as soon as possible. The Board believes that some HMDA reporters, especially the largest ones, will not be able to fully implement the new rules by January 1, 2003, without jeopardizing the quality and usefulness of the data and incurring substantial additional implementation costs that could be avoided by a postponement. Accordingly, the Board is changing the effective date of the amendments from January 1, 2003, to January 1, 2004. The Board is, however, adopting an interim amendment to Appendix A, effective January 1, 2003, mandating the use of 2000 census data.
