This Amendment No. 1 to Schedule 13D (this "Amendment") amends the
below-indicated items from the Schedule 13D previously filed by or on behalf of
the undersigned parties (the "Reporting Persons") (the "Schedule 13D"), by
supplementing such Items with the information below:
Item 2. Identity and Background
The D3 Funds, which are identified in response to Item 4, are Washington
State limited partnerships (except for the DIII Offshore Fund, L.P., which is a
Bahamian limited partnership). The D3 Funds are filing this Amendment, together
with: Nierenberg Investment Management Company, Inc., a Washington State
corporation, which is the general partner of all of the D3 Funds except the DIII
Offshore Fund, L.P.; and Nierenberg Investment Management Offshore, Inc., a
Bahamian corporation, which is the general partner of the DIII Offshore Fund,
L.P., and is a wholly-owned subsidiary of Nierenberg Investment Management
Company, Inc.
Item 3. Source and Amount of Funds or Other Consideration
Reference is made to Item 4 of this Amendment, which is incorporated by
reference in response to this Item.
Item 4. Purpose of Transaction
Effective June 30, 2006, four of the D3 Funds, namely (i) the D3 Family
Fund, L.P., (ii) the D3 Bulldog Fund, L.P., (iii) the D3 Children's Fund, L.P.,
and (iv) the D3 Family Retirement Fund, L.P., (collectively the "Participating
Funds") effected a consolidation of their respective assets and operations (the
"Consolidation"). The Consolidation was implemented through a series of
simultaneous transactions approved by the constituent partners of each of the
Participating Funds, including the following: (i) approximately 80% of the fair
market value of the assets of D3 Family Fund were transferred and contributed to
D3 Bulldog Fund; (ii) all of the assets of D3 Children's Fund were transferred
and contributed in separate parts to each of D3 Bulldog Fund and D3 Family Fund;
and (iii) all of the assets of D3 Retirement Fund were transferred and
contributed in separate parts to each of D3 Bulldog Fund and D3 Family Fund. To
the extent the transferred and contributed assets of the Participating Funds
consisted of any shares of the class previously reported on the Schedule 13D as
being beneficially owned by any such Participating Fund (the "Shares"), for all
purposes and transactions involved in the Consolidation the Shares were valued
at fair market value as represented by the (closing price) as at June 30, 2006
and treated as having been re-allocated internally amongst the Participating
Funds at the fair market value.
As a result of the Consolidation, each of D3 Children's Fund and D3
Retirement Fund no longer beneficially owns any Shares, and correspondingly, the
number of Shares owned beneficially by each of D3 Family Fund and D3 Bulldog
Fund has increased. After giving effect to the Consolidation, the aggregate
beneficial ownership of Shares by the Participating Funds and their respective
general partners has not changed. Further, the Consolidation did not include or
involve the fifth fund, DIII Offshore Fund, L.P. Accordingly, after giving
effect to the Consolidation, the aggregate beneficial ownership of Shares on the
part of all filing persons as a group has not changed.
9
Also see Item 5 of this Amendment.
Item 5. Interest in Securities of the Issuer.
(a, b) The Reporting Persons, in the aggregate, beneficially own 1,780,401
common shares, constituting approximately 9.4% of the outstanding Shares.
(c) As a result of the Consolidation, including any internal re-allocation
of Shares amongst the Participating Funds as described in Item 4 of this
Amendment (which is incorporated by reference in response to this Item 5), the
following transfers of Shares among the D3 Family Funds may be deemed to have
occurred, the transaction date of all such transfers being June 30, 2006.
D3 Children's Fund: transferred 71,153 Shares, constituting all of its
Shares
D3 Retirement Fund: transferred 274,361 Shares, constituting all of its
Shares
D3 Family Fund: number of Shares decreased from 804,365 to 339,454
representing approximately 1.8% of the outstanding Shares
D3 Bulldog Fund: number of Shares increased from 234,892 to 1,045,317
representing approximately 5.5% of the outstanding Shares
(d) On June 30, 2006, D3 Children's Fund and D3 Retirement Fund ceased to
be the direct beneficial owners of any Shares and ceased to be members of a
filing group with the other three Funds.
Item 6. Contracts, Arrangements, Understandings or Relationships with the Issuer
Exhibit 1 to this Amendment is hereby incorporated by reference in
response to this item.
Also see Item 4 of this Amendment.
Item 7. Material to be filed as Exhibits
Exhibit 1 to this Amendment is the form of document used to effect the
transfer of (among other assets) Shares pursuant to the consolidation.
Exhibit 2 to this Amendment is the joint filing agreement pursuant to
which all of the filing persons have authorized the filing of this Amendment as
a group.
