NEW YORK STOCK EXCHANGE
2ND QUARTER FINANCIAL ANNOUNCEMENT TELECONFERENCE
AUGUST 15, 2005


RA: Rich Adamonis of the New York Stock Exchange here with Amy Butte as well as
David Karp of our law firm, Wachtell Lipton. We're here to discuss our second
quarter earnings. The press release has been issued. What I'd like to do is
offer Amy for a few opening remarks on the second quarter financials. Please
note, too, that questions will follow. We'd like you to identify yourself and
your affiliation when you ask a question. Know too that the forward-looking
legend that appears in the press release also applies to this discussion. Now,
Amy Butte.

AB: Good afternoon. I think today's results really indicate that we are on our
way to where we want to be as an organization. First, we are positioning
ourselves for growth. Second, we are managing our business to be more efficient.
All these efforts, whether investment and growth, expense management, and what I
will call blocking and tackling are setting the stage for incremental operating
leverage at the New York Stock Exchange. First, what I am going to do is go
through a little bit of summary results, give you some more details on the
consolidated financial results. Once again, highlights relative to our
positioning. And then, open up the call for questions.

The New York Stock Exchange for the second quarter of 2005 reported pre-tax
income of $21.6 million, down versus $44 million in the first quarter of 2005,
however, up materially versus the $4 million that was reported in the second
quarter of 2004. Revenues of $276 million were down 4.2 percent versus the prior
quarter but up 1.6 percent versus the year over year period, at $272 million.





Expenses increased 4.1 percent to $255 million. However, were down five percent
versus the prior year. Accounting for taxes and minority interest, our net
income totaled $13 million for the second quarter, versus $26 million in the
first quarter of 2005, and up materially from the five million in the second
quarter of 2004. On a normalized basis, our results show even more improvement,
particularly on a year over year basis. Taking out unusual items, both revenues
and expenses, our pre-tax totaled $18.2 million for the second quarter of 2005,
versus $20.1 million in the first quarter of 2005, and a negative $2.4 million
in the second quarter of 2004.

I will highlight some of those unusual items when we get into the detail. But
they are primarily driven by expense reimbursements, for insurance recovery,
fines, and other unusual items. All in, we produced for the quarter, a pre-tax
margin of 7.8 percent on a reported basis for the quarter, and 6.7 percent on a
normalized basis.

In terms of details on that, let me take you through each one of the revenue and
expense lines. Listing revenues in the second quarter totaled $85.5 million
versus $86 million in the first quarter of 2005, and $82 million in the second
quarter of 2004. Net new listings for the quarter totaled 36, versus a similar
amount in the first quarter of 2005, but up more than 20 percent versus the 30
new listings in the first quarter of 2004. Trading fees equaled $38 million,
flat, to slightly down versus prior periods, as New York Stock Exchange average
daily volume actually increased on a year over year basis by six percent, but
fell five percent on a link-quarter basis.

As many of you have heard me talk about before, our existing fee structure,
which we are working to change, as we move towards 2006, particularly due to
dollar caps and the two percent commission caps, has limited our ability to grow
our trading revenues as the underlying drivers, our average daily volume, have
also moved up over time. Market data fees totaled $46.3 million for the second
quarter of 2005, up 4.8 percent versus the $44 million in the first quarter of
2005, and ten percent versus the $42 million in the second quarter of 2004.

A primary driver of that growth is growth in New York Stock Exchange proprietary
products, which increased eight percent on a link-quarter basis, and more than
40 percent year over year. As we note in some of our statistics that are
incorporated into the release, our market share of trades still totaled 89
percent during the second quarter, slightly down from prior periods. Regulatory
fees equaled $32.2 million versus $29 million in the first quarter of 2005, and
a similar amount in the second quarter of 2004. As many of you know, these fees
are based primarily on regulatory service fees that are focus revenues reported
by our member firms. The 11 percent growth quarter to quarter, and 12





percent growth year over year is really the result of material growth and
reported gross focus revenue. Those grew 27 percent year over year, and 22
percent on a link-quarter basis.

Really highlighting some of the strong blocking and tackling, and changes being
undertaken by Rick Ketchum and Grace Vogel in the Member Firm Regulation area,
to encourage our member firms to report more of their revenues within their U.S.
broker-dealer.

Facility and equipment fees totaled $12.3 million, down about 2.4 percent versus
the prior quarter, and 1.6 percent in the year ago period. Membership fees were
also down, materially on a percentage basis, not that much on a dollar basis.
Finally, data processing fees total approximately $48 million for the second
quarter, versus $45 million in the first quarter, and $53.5 million in the
second quarter of 2004. Once again, these represent the fees from non-New York
Stock Exchange customers, of SIAC.

Investment and other income totaled $13.8 million in the second quarter, versus
$31.8 in the first quarter of 2005, and $12.9 million in the second quarter of
2004. Investment and other income represented the largest percentage of that, of
$10.4 million in the second quarter, as compared to fines as well as other
income from SIAC. As many of you recall, we collected a $19 million fine from
Morgan Stanley in the first quarter of this year, which represents the material
charge in terms of this line item.

As we move over to expenses, our compensation equaled $127.4 million in the
second quarter of 2005, flat with the first quarter, and down slightly versus
the $132.6 reported in the second quarter of 2004. New York Stock Exchange
operating net revenue represented 33 percent in this quarter as compared to 29
percent in the first quarter of 2005, and a similar 33 percent in the second
quarter of 2004. Once again, that is on a non-GAAP basis, but will help to give
you a sense of where we are in terms of our compensation ratios, and our market
business as compared to the consolidated effect.

Systems expense totaled approximately $32 million in the second quarter of 2005.
Flat versus the first quarter of 2005, but down seven percent versus the second
quarter 2004 figure of $34.3 million. This number in the consolidation includes
changes that take place at SIAC, which once again, operates on a cost recovery
model. Depreciation expense totaled $26.4 million in the second quarter of 2005,
flat versus the first quarter, but up versus the $22 million in the second
quarter of 2004. In December of 2004, we initiated changes in our depreciation
policies, as we shortened the useful lives that we used in our depreciation.
That led to higher reported depreciation expense.





The occupancy expense remained flat in the second quarter of 2005 at $17.3
million. However, G&A showed an increase versus the first quarter, but a
down-tick versus the second quarter of 2004, at $17.9 million versus $15 million
on a link-quarter basis, and $22.3 million in the year ago time period. This is
beginning to show the results of changes in our advertising spending, changes in
some of the policies the procedures that we've begun to implement, as well as
just general changes in our accrual policies in terms of accounting for our G&A.

Professional services equaled $35.7 million in the second quarter of 2005, as
compared to $28 million in the first quarter this year, and $41.1 million in the
year ago period. As we've been reporting, our legal expense continues to be a
major driver of our professional services line. Those numbers equaled $8.7
million in the second quarter, as compared to $6.3 million in the first quarter,
and closer to $13 million in the second quarter of 2004. We have not included a
large amount of merger-related expenses within our numbers. We estimate
approximately one million of our merger-related expenses to date have been
capitalized in the second quarter. The remaining will be capitalized as we move
forward, and move closer to a closing date.

In terms of segment reporting, I want to give you a sense of, although we have
not provided complete details on a segment basis, I think many of you have seen
our segment results within the S-4. As I started to mention before, New York
Stock Exchange market financial performance represented revenue of $225 million
in the second quarter, expenses of $209 million, and pre-tax of $16 million. On
a normalized basis, it would be pre-tax of $12.6 million, as compared to $24.1
in the first quarter of 2005, and a negative $3.7 in the second quarter of 2004.

For SIAC, on a segment basis, $116.9 million of revenues, expenses of $111
million for a pre-tax of $5.6 million. That compares to a pre-tax of minus $4
million in the first quarter of 2005, and a pre-tax of $1.3 million in the
second quarter of 2004. Once again, the segments do not incorporate the process
of consolidation, which you are seeing through the consolidated results in the
press release. And also, highlight once again the cost recovery nature of SIAC's
business model.

Once again, I want to summarize kind of how we see our positioning for growth
efficiency, and just general operating leverage expansion. In terms of
positioning for growth, I would highlight a few things. First, year to date, our
net new listings are up 16 percent to 73 in 2005 versus 63 in 2004. Second, we
continue to expand and make commitments to our ETF business. As part of our BGI
deal, we added 61 ETFs, and we have an additional 15-plus





products in our pipeline for the upcoming quarters. To date, we represent
approximately 90 of total 190 ETFs in the marketplace.

Third, our fixed income build-out is the automated bond system which was
launched in 1977, continues to gain momentum, with our SEC exemption that came
recently, plans to have over 5,000 issues in our bond system. And we are
continuing to make a commitment to upgrading our technology, and communicating
with the street.

Finally, our revenue analysis that we began to talk about well over a year ago
is fully underway. Our philosophy, as a reminder, is not necessarily to increase
fees in the short term, or in aggregate, but to position the NYSE's revenue to
grow with underlying drivers on a go-forward basis. To this end, we have a
filing with the SEC related to our listing fees, and we've also been talking to
our member firms surrounding floor and transaction fee changes. We will seek to
implement those changes at the beginning of next year, such that we can continue
to grow the underlying drivers. And once again, I just encourage people to look
at trading fees as they have stayed flat, even as trading volume has either gone
up, or gone down. Our goal is to be able to move with the underlying growth in
our anticipated market volume.

Improved efficiencies. We continue to make investments in our corporate
governance and regulatory systems. As a reference, regulation and corporate
governance increases represent more than 80 percent of the year to date increase
in non-legal, non-SIAC professional services expense. Once again, our legal
expense is leveling off. It's down 31 percent year over year, and 25 percent
year to date. And we believe that it will continue at kind of a downward trend,
not including merger-related expenses, as we move forward in the rest of the
year.

Finally, G&A is down year over year, and ten percent year to date. Our operating
G&A is down further than the consolidated results even illustrate. Reduced
advertising is the primary driver, but we are making inroads with new policies
and procedures specifically as related to T&E, and just general spending within
the organization.

Finally, I'd like to highlight our blocking and tackling, or what I call good
business initiatives. There are two that I'd like to highlight. First, we're
seeing improved financial results from our investment portfolio. While the
average investment portfolio assets stayed flat on a year over year basis,
investment returns increased nearly 50 percent versus that year ago period. If
you incorporate the reallocation to tax-free securities and the impact on our
overall tax rate, we think the benefit is even greater.

And finally, I'd like to highlight the changes in our regulatory member firm
structure. Our regulatory fees increased 11 percent quarter to quarter, and
approximately the same year over year, as our reported growth focus revenue
increased by more than 30 percent on that same period basis. There was no change
in pricing, rather it represents the





effort by our member firm regulation department to encourage a greater
percentage of the business being done in the U.S. broker-dealer.

With that, I'd like to open up the call for questions.

(RA): And please identify your name and affiliation with your question.

W: This conference is now in question and answer mode. To alert the speaker that
you have a question, press one, then zero. Each question will be asked in the
order it was received.

EO: This is Edgar Ortega, Bloomberg News, New York.

AB: Hi, Edgar.

EO: How are you?

AB: Good, how are you?

EO: Good, thank you. I just wanted to, I guess, I have two questions. First, if
you might be able to help me out and give me a little bit more of a sense. You
mentioned that your results are due on the one part, you know, to the good
blocking and tackling, minding your expenses. Does this include some staff cuts
that you've seemed to outline in the S-4? Or, is it mostly the kind of impact in
terms of you know, lower legal expenses that you kind of outlined a little bit?

AB: This does not incorporate any staff or head count reductions that were
outlined in the S-4. It is primarily due to legal expense adjustments,
particularly on a year over year basis. Reduced advertising expenditures,
primarily on a year over year basis. As well as lower G&A expenses pretty much
across the organization, particularly in travel and entertainment, and kind of
general spending, due to changed policies that were implemented in December of
2004.

In terms of the head count reductions that were identified within the S-4, those
are based relative to our 2005 budgeted head count numbers of 1741. At the time
that the deal was announced, we identified that if we simply held our head count
flat, we would reach those objective. And we continue as an organization to
manage through whether we need to make those reductions in order to meet our
expense targets.





EO: Okay. Can you talk maybe more broadly about you know, maybe is it a new
emphasis at the Exchange to be so mindful about expenses? You know, can you kind
of give us a broader thought on the kind of trends you're seeing there?

AB: That's a great question. Since, I would say, definitely since John's
arrival, and my arrival at the Exchange, kind of going back to January of 2004,
we've sought to really interject more of a public company mindset around our
daily operating results. I think that historically, the Exchange operated as a
not-for-profit entity. When you move to a for-profit structure, and I think
particularly as you contemplate and move towards not just a for-profit
structure, but a public for-profit structure, that implies a very different
mindset. We've changed a lot of our policies relating to procurement, relating
to travel and entertainment. Just relating to practices across the Exchange. And
we're seeking to kind of see those inroads on our financial results.

EO: Okay, and just last one, if I may. I talked briefly about your investment
income. I understand from the S-4, that you reconfigured that investment
portfolio at the end of last year. Is that why you're having these sort of
better results? And can you just help us a little bit to understand the kind of
structure of that portfolio? It's mostly invested in fixed income securities, as
I understand. But you know, are there other guidelines that you have in terms of
how you invest that money?

AB: Right. It is fixed income related. It still has a very short duration. The
average duration of the portfolio is less than 1.3 years. So, it's still very
mindful of kind of a low risk point of view towards our cash position. If you
recall, we have cash obligations related to the deal that we're very mindful of
as well. However, our after-tax return has gone from a negative number to
something that is much more positive on a very similar sized portfolio.

EO: Are there, I mean, do you have to hold that amount of money in investments
because of regulatory issues? Or, is it just you know, money that the Exchange
has to invest in a variety of different ways, and you know, it decided to
allocate it in fixed income securities in this way?

AB: That's actually a good question. Our average portfolio is well over $1.1
billion. However, excluding the kind of SEC activity assessment fees that we pay
to the SEC twice a year, the amount that would define as kind of free cash
fluctuates closer to about $850 million. And that $850 million represents cash
that we are not putting into use in different ways. We've continued to,
historically, there's been a very conservative point of view relative to that
cash. If you recall, going back a few years, there's was consideration of
building a new trading floor, taking on a new building. And it just has a very
conservative approach. As we move forward, we're looking to kind of develop more






of a return on investment philosophy, related to that cash on hand that's
available for investments and other corporate purposes.

RA: May I ask to move on to the next questioner please?

EO: Thank you.

JD: Oh, hi, this is James Doran, with The Times of London. Firstly, stop me if
this question's already been asked. I just wanted to ask about the million
dollars of merger related expenses that you mentioned being capitalized in Q2,
with the rest being capitalized at some point in the future. Are you able to
quantify how much that remains to be capitalized, and why you chose to
capitalize this small amount in Q2 this year?

AB: I will tell you, it is much larger than the million dollars in terms of
where we're estimating it right now. I would prefer not to give that dollar
figure as it stands, because I would assume that it will continue to grow as we
move forward with ...

JD: Can you give us a ballpark?

AB: You know, I would say approximately $14 - $15 million is where it stands
right now. And due to the fact that we are the buyer of Archipelago we have
different accounting rules, which basically suggest we can't expense it to date.
And we've only capitalized a small portion.

JD: Okay. Why were you able to capitalize on a small portion? I'm just wondering
why any of it's capitalized at all. That's all.

AB: It's just a small amount that's based on what it was allocated towards. And
I just wanted to identify that we had a very small amount without our second
quarter results.

JD: Thanks very much.

RA: Next questioner please? If there are no more questions, we'll give a moment,
and then we'll close the call. If you have a question, please enter.





RA: Thank you very much. If you have any question, feel free to call me, Rich
Adamonis. Eric Ryan, or Ray Pellecchia. You have our numbers. We'll be happy to
take your calls and make Amy available. Thank you very much.
