(1)	Acquired pursuant to a dividend reinvestment feature of the issuer's non-employee directors' stock incentive plan in connection with restricted stock units held by the reporting person.
(2)	Phantom stock is reported in units vs. shares in the D&B Common Stock Fund of the issuer's non-employee directors' deferred compensation plan (the "Plan").

Based on the $90.43 closing price of the issuer's common stock on the transaction date, each unit corresponds to approximately 2.67 shares.
(4)	The reporting person may transfer these phantom stock units to alternative investment funds in the Plan.
(5)	These phantom stock units are payable in cash after the reporting person ceases to be a member of the issuer's board of directors.
(6)	Each phantom stock unit represents the right to receive one share of the issuer's common stock.
(7)	These phantom stock units are payable in shares after the reporting person ceases to be a member of the issuer's board of directors.
