	Neither FMR Corp. nor Edward C. Johnson 3d, Chairman of FMR

funds' Boards of Trustees.  Fidelity carries out the voting of
the shares under written guidelines established by the funds'
Boards of Trustees.

	Fidelity Management Trust Company, 82 Devonshire Street,
Boston, Massachusetts 02109, a wholly-owned subsidiary of FMR
Corp. and a bank as defined in Section 3(a)(6) of the Securities
Exchange Act of 1934, is the beneficial owner of 1,563,200 shares
or 2.853% of the common stock outstanding of the Company as a

Accordingly, through their ownership of voting common stock and

	Fidelity International Limited, Pembroke Hall, 42 Crowlane,

shares or 1.079% of the common stock outstanding of the Company.
Additional information with respect to the beneficial ownership
of Fidelity International Limited is shown on Exhibit B.



EXHIBIT to SCHEDULE 13G - TO BE INCLUDED IN STATEMENTS
FILED PURSUANT TO RULE 13d-1(c)

	Pursuant to instructions in Item 7 of Schedule 13G, this
Exhibit has been prepared to identify Fidelity International
Limited, Pembroke Hall, 42 Crow Lane, Hamilton, Bermuda, a
Bermudan joint stock company incorporated for an unlimited
duration by private act of the Bermuda Legislature (FIL) and an
investment adviser to various investment companies (the
"International Funds") and certain institutional investors, as a
beneficial owner of the 591,530 shares or 1.079% of the common
stock outstanding of CheckFree Holdings Corporation.

	Prior to June 30, 1980, FIL was a majority-owned subsidiary
of Fidelity Management & Research Company (Fidelity), a wholly-
owned subsidiary of FMR Corp.  On that date, the shares of FIL
held by Fidelity were distributed, as a dividend,  to the
shareholders of FMR Corp.  FIL currently operates as an entity
independent of FMR Corp. and Fidelity.  The International Funds
and FIL's other clients, with the exception of Fidelity and an
affiliated company of Fidelity, are non-U.S. entities.

	A partnership controlled by Edward C. Johnson 3d and members
of his family owns shares of FIL voting stock with the right to
cast approximately 39.89% of the total votes which may be cast by
all holders of FIL voting stock.  Mr. Johnson 3d is Chairman of
FMR Corp. and FIL.  FMR Corp. and FIL are separate and
independent corporate entities, and their Boards of Directors are
generally composed of different individuals.  Other than when one
serves as a sub adviser to the other, their investment decisions
are made independently, and their clients are generally different
organizations.

	FMR Corp. and FIL are of the view that they are not acting as
a "group" for purposes of Section 13(d) under the Securities
Exchange Act of 1934 (the "1934" Act) and that they are not
otherwise required to attribute to each other the "beneficial
ownership" of securities "beneficially owned" by the other
corporation within the meaning of Rule 13d-3 promulgated under
the 1934 Act.  Therefore, they are of the view that the shares
held by the other corporation need not be aggregated for purposes
of Section 13(d). However, FMR Corp. is making this filing on a
voluntary basis as if all of the shares are beneficially owned by
FMR Corp. and FIL on a joint basis.

	FIL has sole dispositive power over 591,530 shares owned by
the International Funds. FIL has sole power to vote or direct the
voting of 591,530 shares of common stock held by the
International Funds as reported above.
