News for those of you nfused about how to mply with the Securities and Exchange mission’s new mandate to use XBRL technology in financial reporting: A new supply of nfusion has just arrived.

The latest batch of frustration erupted earlier this month, when largest mpanies in America had to start filing period reports “tagged” in XBRL ding. Those tags me from a taxonomy of acunting terms that neatly matches up the tags to ncepts in U.S. Generally Aepted Acunting Principles.

Except, um—GAAP was replaced on July 1 by the new Acunting Standards dification. The existing XBRL taxonomy doesn’t match up to acunting terms in the dification, and won’t be aurate for filings that cite dification. As you can imagine, this discrepancy has left financial reporting executives rather peeved.

Yesterday, however, I heard rumor that XBRL U.S. (the nsortium that publishes the taxonomies) has created a temporary solution for those mpanies facing immediate filing deadlines. To get to the bottom of things, I ntacted my spy attending XBRL U.S.’s nference happening out in California this week and asked him for the sop.

The bottom line is this: Within the next two weeks, XBRL U.S. will publish an “extension taxonomy” that reflects acunting terms acrding to the new Acunting Standards dification. When a mpany submits a periodic report to the SEC based on the new dification—and that will be mandatory me Sept. 15—it should also include the new extension taxonomy as part of its attached XBRL exhibits. That gets you off the hook.

XBRL U.S. nfirms my spy’s summary as rrect, although not surprisingly the officials there see things differently. Michelle Savage, the group’s chief spokeswoman, says XBRL U.S. and the Financial Acunting Standards Board have been planning for dification all along, and releasing an extension taxonomy in mid-August “will give preparers plenty of time to review the new and old references before the FASB requirements in September.”

Some technical background: To create XBRL filings, mpanies use a “linkbase,” which is really just a database that nnects XBRL tags to specific terms in U.S. acunting. The 2008 taxonomy released last year ntained one linkbase; the 2009 taxonomy released this year ntains another, to reflect new acunting rules adopted in the last six months. dification now needs a linkbase of its own, and that is what’s ming next month.

The irritation springs from early filers that had been using the 2009 taxonomy since, well, that’s what they were told to do, and just as filings are about to begin they must now change urse. Savage says releasing an extension taxonomy is standard procre; XBRL U.S. wants to publish only one formal update each year, and will then follow up with extension releases as needed when a major change (like dification) arises in the urse of the year.

Thankfully, this should all pass (like a kidney stone, some would say) when XBRL U.S. publishes its 2010 taxonomy sometime around January. That document should be in full acrdance with the Acunting Standards dification, and all will be roses.

For now, however, my spy reports “lots of nfusion” out there about XBRL—an unfortunate circumstance, since XBRL is still in its first year of adoption and needs all the support it can get.
