For purposes of determining whether, within a 12-month period, an AMC oversees an appraiser panel of more than 15 State-certified or State-licensed appraisers in a State or 25 or more State-certified or State-licensed appraisers in two or more States pursuant to §225.191(d)(1)(iii)-

(a) An appraiser is deemed part of the AMC's appraiser panel as of the earliest date on which the AMC:

(1) Accepts the appraiser for the AMC's consideration for future appraisal assignments in covered transactions or for secondary mortgage market participants in connection with covered transactions; or

(2) Engages the appraiser to perform one or more appraisals on behalf of a creditor for a covered transaction or secondary mortgage market participant in connection with a covered transaction.

(b) An appraiser who is deemed part of the AMC's appraiser panel pursuant to paragraph (a) of this section is deemed to remain on the panel until the date on which the AMC:

(1) Sends written notice to the appraiser removing the appraiser from the appraiser panel, with an explanation of its action; or

(2) Receives written notice from the appraiser asking to be removed from the appraiser panel or notice of the death or incapacity of the appraiser.

(c) If an appraiser is removed from an AMC's appraiser panel pursuant to paragraph (b) of this section, but the AMC subsequently accepts the appraiser for consideration for future assignments or engages the appraiser at any time during the twelve months after the AMC's removal, the removal will be deemed not to have occurred, and the appraiser will be deemed to have been part of the AMC's appraiser panel without interruption.

(d) The period for purposes of counting appraisers on an AMC's appraiser panel may be the calendar year or a 12-month period established by law or rule of each State with which the AMC is required to register.
