ITEM 8.01  OTHER EVENTS

On March 22, 2006, the New York Stock Exchange (the "NYSE") received approval
from the Securities and Exchange Commission (the "Commission") to begin full
implementation of its Hybrid MarketSM initiative, which will enable the NYSE to
integrate its traditional floor-based auction market with enhanced automated
trading functionality. The Commission's order approving the proposed rule
changes is available on the Commission's Web site at
http://www.sec.gov/rules/sro/nyse/34-53539.pdf.

Designed to offer customers greater choice in order-execution services, the NYSE
Hybrid Market expands customer ability to trade instantaneously with certainty
and anonymity without sacrificing the price improvement and market quality of
the floor-based NYSE auction market. Maintaining the Exchange's ability for
price improvement across all its order-execution options, the NYSE Hybrid Market
will provide customers with choices that include sub-second automated, anonymous
transactions for NYSE-listed stocks or the opportunity to have orders
represented in the auction market with the benefits of human judgment and
accountability at the central point of sale.

On March 22, 2006, NYSE Group issued a press release entitled "NYSE Hybrid
MarketSM Gains SEC Approval." A copy of that press release is attached as
exhibit 99.1 to this report and is incorporated herein by reference.
