Sec. 2001.22  Derivative classification [2.1].

    (a) General. Information classified derivatively on the basis of 
source documents or classification guides shall bear all markings 
prescribed in Sec. 2001.20 and Sec. 2001.21, except as provided in 
this section. Information for these markings shall be carried forward 
from the source document or taken from instructions in the appropriate 
classification guide.
    (b) Source of derivative classification. (1) The derivative 
classifier shall concisely identify the source document or the 
classification guide on the ``Derived From'' line, including the agency 
and, where available, the office of origin, and the date of the source 
or guide. An example might appear as:

Derived From: Memo, ``Funding Problems,'' October 20, 2003, Office of 
Administration, Department of Good Works

    or

Derived From: CG No. 1, Department of Good Works, dated October 20, 2003

    (i) When a document is classified derivatively on the basis of more 
than one source document or classification guide, the ``Derived From'' 
line shall appear as: Derived From: Multiple Sources
    (ii) The derivative classifier shall maintain the identification of 
each source with the file or record copy of the derivatively classified 
document. When practicable, this list should be included in or with all 
copies of the derivatively classified document.
    (2) A document derivatively classified on the basis of a source 
document that is itself marked ``Multiple Sources'' shall cite the 
source document on its ``Derived From'' line rather than the term 
``Multiple Sources.'' An example might appear as:

Derived From: Report entitled, ``New Weapons,'' dated October 20, 2003, 
Department of Good Works, Office of Administration

    (c) Reason for classification. The reason for the original 
classification decision, as reflected in the source document(s) or 
classification guide, is not required to be transferred in a derivative 
classification action. If included, however, it shall conform to the 
standards in Sec. 2001.21(a)(3).
    (d) Declassification instructions. (1) The derivative classifier 
shall carry forward the instructions on the ``Declassify On'' line from 
the source document to the derivative document, or the duration 
instruction from the classification or declassification guide.
    (2) When a document is classified derivatively on the basis of more 
than one source document or more than one element of a classification 
guide, the ``Declassify On'' line shall reflect the longest duration of 
any of its sources.
    (i) When a document is classified derivatively either from a source 
document(s) or a classification guide that contains the declassification 
instruction, ``Originating Agency's Determination Required,'' or 
``OADR,'' or from a source document(s) or a classification guide that 
contains any of the

exemption markings X1 through X8. Unless otherwise instructed by the 
original classifier, the derivative classifier shall carry forward:
    (A) The fact that the source document(s) was marked with this 
instruction; and
    (B) The date of origin of the most recent source document(s), 
classification guides, or specific information, as appropriate to the 
circumstances.
    (ii) Examples might appear as:

Declassify On: Source Marked ``OADR'', Date of source: October 20, 1990
    or

Declassify On: Source Marked ``X1'', Date of source: October 20, 2000

    (iii) Either of these markings will permit the determination of when 
the classified information is 25 years old and, if permanently valuable, 
subject to automatic declassification under section 3.3 of the Order.
    (e) Overall marking. The derivative classifier shall conspicuously 
mark the classified document with the highest level of classification of 
information included in the document, as provided in Sec. 2001.21(b).
    (f) Portion marking. Each portion of a derivatively classified 
document shall be marked in accordance with its source, and as provided 
in Sec. 2001.21(c).
