------------
(1)  Pre-tax income for 2002 includes the reversal of a restructuring charge of
     $6,405 and an investment impairment charge of $2,000. Excluding these
     items, the ratio of earnings to fixed charges would have been 4.0x. For
     additional information regarding the restructuring and investment
     impairment items, see "Management's Discussion and Analysis of Financial
     Condition and Results of Operations" included elsewhere in this
     registration statement to which this exhibit relates.

(2)  Pre-tax income for 2001 includes a restructuring charge of $18,556 and an
     investment impairment charge of $11,432. Excluding these charges, the ratio
     of earnings to fixed charges for 2001 would have been 5.3x. For additional
     information regarding the restructuring and investment charges, see
     "Management's Discussion and Analysis of Financial Condition and Results of
     Operations" included elsewhere in this registration statement to which this
     exhibit relates.

(3)  Pre-tax income for 2000 includes in earnings a gain on the disposition of
     businesses of $86,495 and a special benefit of $15,771 resulting from the
     restructuring of the CenDon relationship. Excluding these special items,
     the ratio of earnings to fixed charges for 2000 would have been 4.0x. For
     additional information regarding the disposition of businesses and the
     restructuring of the CenDon relationship, see "Management's Discussion and
     Analysis of Financial Condition and Results of Operations" included
     elsewhere in this registration statement to which this exhibit relates.

(4)  Prior to July 1, 1998, Donnelley operated as part of The Dun & Bradstreet
     Corporation. Interest expense for 1998 represents interest incurred on debt
     from July 1, 1998.

(5)  For the three months ended March 31, 2003, earnings are inadequate to cover
     fixed charges. The Company would need an additional $66,000 of earnings in
     order to cover its fixed charges.

     However, earnings for the quarter ended March 31, 2003 include the impact
     of purchase accounting adjustments relating to the SPA acquisition that
     prevented us from recognizing in earnings revenue and expenses for those
     directories that published prior to the acquisition. Assuming that the
     revenue and expenses for those directories that published prior to the
     acquisition were recognized in earnings under our deferral and amortization
     method, the ratio of earnings to fixed charges would have been 1.8x.

(6)  Represents 1/3 of rent expense, which management believes is representative
     of the interest component.
