    --  Diluted earnings per share of 61 cents in Q4/12
    --  Adjusted diluted earnings per share of 95 cents, excluding 18
        cents per share of Maple Transaction and Integration costs and
        16 cents per share of amortization of intangible assets related
        to acquisitions.
    --
    --  Cash flows from operating activities of $29.8 million in Q4/12

TORONTO, Feb. 6, 2013 /CNW/ - TMX Group Limited [TSX:X] announced results for 
the fourth quarter and year ended December 31, 2012.

Commenting on Q4 and 2012, Thomas Kloet, Chief Executive Officer of TMX Group 
said "2012 was a year of important change for TMX Group with the successful 
completion of the Maple transaction and the ongoing integration of the TMX 
Group Inc., CDS and Alpha businesses. We ended the year a stronger and more 
internationally competitive organization. As we progress through the 
integration, we are focused on further enhancing our customer service, driving 
new innovation for the benefit of the marketplace and identifying new 
opportunities for growth."

"This significant activity was achieved against a backdrop of continued 
economic uncertainty, which impacted our operating and financial results for 
the fourth quarter and the year. These same impacts were experienced by many 
of our competitors around the world. However, despite these macroeconomic 
pressures to both trading and listing activity, our businesses continued to 
compete successfully. As economic conditions improve and market activity 
resumes, we are confident in the opportunity for growth across our 
diversified, multi-asset class portfolio of businesses."

Michael Ptasznik, Chief Financial Officer of TMX Group said "Income from 
operations in Q4/12 was down 6.5% as compared to TMX Group Inc. in Q4/11 as 
lower expenses in certain areas and the addition of CDS and Alpha were more 
than offset by the amortization of intangible assets that related to the Maple 
transaction and the lower revenue that resulted from reduced market activity. 
We remain on track to complete the integration of CDS and Alpha and achieve 
our cost synergy targets in Q1/14."

Important Information

The financial information for the fourth quarter ended December 31, 2012 
reflects the first full quarter for TMX Group Limited, following the 
completion of the two-step acquisition of TMX Group Inc. on September 14, 2012 
and the acquisitions of The Canadian Depository for Securities Limited (CDS) 
and Alpha Trading Systems Inc. and Alpha Trading Systems Limited Partnership 
(collectively, Alpha) on August 1, 2012 (collectively, the Maple Transaction).

Maple Group Acquisition Corporation (or Maple, renamed TMX Group Limited) was 
a special acquisition corporation and the most significant aspect of the Maple 
Transaction was the purchase of TMX Group Inc., which was the publicly traded 
company. The approach taken in this press release is intended to provide 
readers with a more complete view of the operating performance and cash flows 
of TMX Group. Our discussion of revenue, operating expenses, net income 
attributable to non-controlling interests and cash flows for the year ended 
December 31, 2012 includes the operating results of TMX Group Inc. from 
January 1, 2012 along with those of CDS and Alpha from August 1, 2012. These 
measures are compared with TMX Group Inc. for the quarter and year ended 
December 31, 2011.

For the most part, the operational comparison has been prepared as if TMX 
Group Inc. acquired CDS and Alpha on August 1, 2012. Management believes that 
this is the most meaningful presentation for the purpose of discussion of our 
results of operations and cash flows.

Three and Twelve Months Ended December 31, 2012 Compared With Three and Twelve 
Months Ended December 31, 2011

The information in the chart below reflects financial information for TMX 
Group Limited for the three and twelve months ended December 31, 2012, 
including the operating results of TMX Group Inc., CDS and Alpha and their 
respective subsidiaries. The comparative financial information for the three 
and twelve months ended December 31, 2011 includes only the accounts of TMX 
Group Limited.

TMX Group Limited (previously Maple) was formed solely for the purpose of 
pursuing the Maple Acquisition along with the CDS and Alpha Acquisitions. 
Prior to the completion of the CDS and Alpha Acquisitions on August 1, 2012 
and the take up of 80% of the common shares of TMX Group Inc. on July 31, 2012 
under the Maple Offer, TMX Group Limited had no material assets and no history 
of earnings and had not commenced commercial operations. Management believes 
that the Q4/11 and 2011 information for TMX Group Limited in this table will 
be of limited use to investors and other users of our financial information in 
evaluating the operating performance and cash flows of our company for the 
comparative periods.

Non-IFRS Financial Measure

Adjusted earnings per share and adjusted diluted earnings per share provided 
below are Non-IFRS measures and do not have standardized meanings prescribed 
by IFRS and are therefore unlikely to be comparable to similar measures 
presented by other companies. We present adjusted earnings per share and 
adjusted diluted earnings per share to indicate operating performance 
exclusive of Maple Transaction costs, integration costs related to the Maple 
Transaction and the amortization of intangible assets related to acquisitions, 
which are adjusted because they are not indicative of underlying business 
performance. Management uses these measures to assess our financial 
performance, including our ability to generate cash, exclusive of these costs 
and to enable comparability across periods.

Supplementary Information For Three Months Ended December 31, 2012 Compared 
With Three Months Ended December 31, 2011

The table below contains TMX Group Limited revenue and operating expenses, 
income from operations and net income attributable to non-controlling 
interests which include the accounts of TMX Group Limited and the operating 
results of TMX Group Inc. and its subsidiaries and the operating results of 
CDS and Alpha and their subsidiaries for the period from October 1, 2012 to 
December 31, 2012. In order to provide a meaningful discussion of the 
results of operations in this press release, we have compared TMX Group 
Limited consolidated revenue and operating expenses, income from operations 
and net income attributable to non-controlling interests of Q4/12 with TMX 
Group Inc. information of Q4/11. This approach is similar to how the results 
would be reported if TMX Group Inc. was the acquirer of CDS and Alpha.

This Q4/11 information differs from the TMX Group Limited consolidated 
financial statements. The TMX Group Limited consolidated financial statements 
reflect only the accounts of TMX Group Limited during 2011.

(b) TMX Group Inc. results for October 1, 2011 to December 31, 2011.

Revenue

Revenue was $181.1 million in Q4/12, up $19.4 million, or 12% compared with 
$161.7 million in Q4/11 due to the inclusion of $22.4 million of revenue from 
CDS and $4.7 million of revenue from Alpha. The increase was partially offset 
by lower revenue from derivatives trading and clearing, cash markets trading, 
and issuer services.

    --  Initial listing fees in Q4/12 were lower primarily due to a 38%
        decrease in the number of new listings on TSX Venture Exchange
        (35 in Q4/12 compared with 56 in Q4/11). This decrease was
        partially offset by a 15% increase in the number of new
        listings on Toronto Stock Exchange (47 in Q4/12 compared with
        41 in Q4/11).
    --  Additional listing fees in Q4/12 decreased compared with Q4/11
        mainly due to Toronto Stock exchange where fees for non
        financing activities were lower (ie. NCIB, filings). An
        increase in the number of financing related transactions was
        offset by lower average value of these transactions.  
    --  Issuers listed on Toronto Stock Exchange and TSX Venture
        Exchange pay annual sustaining listing fees primarily based on
        their market capitalization at the end of the prior calendar
        year, subject to minimum and maximum fees. The decrease in
        sustaining listing fees was due to the overall lower market
        capitalization of listed issuers on both exchanges (combined
        $2,051.1 billion at the end of 2011 compared with $2,278.1
        billion at the end of 2010). The decrease was also due to a
        reduction in certain fees effective January 1, 2012.
    --  Other issuer services revenue included higher revenue from
        Equicom, which provides investor relations and corporate
        communications services and $0.7 million of revenue from CDS
        Solutions.

Cash Markets
    --  The increase in cash markets equity trading and clearing
        revenue reflected the inclusion of $3.9 million of revenue from
        CDS clearing and settlement revenue. CDS processed 77.1 million
        exchange trades and 4.4 million non-exchange/OTC trades from
        October 1, 2012 to December 31, 2012.
    --  The increase was also due to $2.1 million of revenue from
        Alpha. There were 7.2 billion securities traded on Alpha from
        October 1, 2012 to December 31, 2012.
    --  Partially offsetting the increase in cash markets equity
        trading revenue was a 21% decrease in the volume of securities
        traded on Toronto Stock Exchange in (19.1 billion securities in
        Q4/12 versus 24.1 billion securities traded in Q4/11); an 11%
        decrease in the volume of securities traded on TSX Venture
        Exchange (10.5 billion securities in Q4/12 versus 11.8 billion
        securities in Q4/11); and a 36% decrease in the volume of
        securities traded on TMX Select (0.45 billion securities traded
        in Q4/12 versus 0.70 billion securities in Q4/11).
    --  The increase in overall cash markets revenue was also partially
        offset by a price decrease in Shorcan fixed income trading that
        was effective April 18, 2012 which more than offset higher
        volumes in Q4/12 compared with Q4/11.

CDS Depository
    --  CDS Depository revenue was $12.1 million. CDS held a daily
        average of approximately 321,000 equities positions with an
        average of 276.2 billion shares and a daily average of
        approximately 180,000 debt positions with an average par value
        of $2.3 trillion on deposit from October 1, 2012 to December
        31, 2012.

Derivatives Markets
    --  The decrease in derivatives markets revenue reflects lower
        revenues from BOX primarily as a result of a 20% decrease in
        BOX volumes (29.3 million contracts in Q4/12 versus 36.4
        million contracts traded in Q4/11). The decrease was also due
        to the impact of the depreciation of the U.S. dollar against
        the Canadian dollar in Q4/12 compared with Q4/11. Revenue from
        BOX was also higher in Q4/11 due to the inclusion of Options
        Regulatory Fees. As of May 14, 2012, the fees charged, and the
        related costs incurred, by the BOX SRO entity are not
        consolidated into TMX Group results. 
    --  The decrease in derivatives markets revenue for Q4/12 was
        somewhat offset by fees earned by CDCC for providing the
        clearing service on REPO transactions as well as bank fees that
        are charged back to Clearing Members (see Other Credit and
        Liquidity Facilities and Guarantee). This service was launched
        on February 21, 2012.
    --  The decrease in derivatives markets revenue was also partially
        offset by an increase in trading and clearing revenue from MX
        and CDCC. Volumes increased by 3% over Q4/11 (14.8 million
        contracts traded in Q4/12 versus 14.4 million contracts traded
        in Q4/11) largely due to increased trading in the BAX contract
        and index derivatives. Open interest was down 7% at December
        31, 2012 compared with December 31, 2011.

Energy Markets
    --  The decrease in energy markets revenue reflects a 21% decrease
        in total energy volume(#) on NGX in Q4/12 compared with Q4/11
        (3.4 million terajoules in Q4/12 compared to 4.3 million
        terajoules in Q4/11), primarily due to a 24% decrease in
        natural gas volumes.
    --  The decrease in revenue was largely offset as a result of NGX
        having deferred less revenue in Q4/12, on a net basis, than in
        Q4/11 due to a decreased level of forward contracts.
    --  The decreased revenue was also due to the impact of the
        depreciation of the U.S. dollar against the Canadian dollar in
        Q4/12 compared with Q4/11.
    --  This decrease was also partially offset by higher revenue from
        Shorcan Energy Brokers driven by higher volumes in Q4/12
        compared with Q4/11.

________________________
(#) NGX total energy volume includes trading and clearing in natural gas, 
crude oil and electricity.

Q4/12(a)     Q4/11(b)     $ increase     % increase

  $47.3        $43.3          $4.0             9%
    --  The increase in revenue was due to the inclusion of $2.6
        million of revenue from Alpha and $1.5 million of revenue from
        CDS. The increase in revenue is also attributable to higher
        revenue from co-location services, TMX Atrium and PC-Bond. The
        increase was also due to higher revenue recoveries related to
        under-reported usage of real-time quotes in prior periods
        during Q4/12 compared with Q4/11.
    --  There was also a 4% increase in the average number of MX market
        data subscriptions (28,359(+) MX market data subscriptions in
        Q4/12 compared with 27,261(+) in Q4/11) and a price increase
        effective April 1, 2012 related to data feeds.
    --  The increased revenue was partially offset by the impact of the
        depreciation of the U.S. dollar and the Euro against the
        Canadian dollar in Q4/12 compared with Q4/11; net price
        reductions on TSX market data subscriptions effective April 1,
        2012, and lower revenue from usage based quotes.
    --  Overall, there was a 5% decrease in the average number of
        professional and equivalent real-time market data subscriptions
        to Toronto Stock Exchange and TSX Venture Exchange products
        (150,633(+) professional and equivalent real-time market data
        subscriptions in Q4/12 compared with 157,830(+) in Q4/11).

    --  Technology services and other revenue includes $4.1 million of
        revenue from CDS services relating largely to SEDAR, SEDI and
        NRD. The current contract is due to expire on October 31, 2013
        and a new service provider is being secured to take over these
        services. We do not expect the operating agreements to be
        renewed beyond October 31, 2013. Any expenses associated with
        the wind down of the business operations have not been recorded
        in the consolidated income statement. Only a portion of the
        ongoing costs associated with this revenue will be fully
        eliminated.
    --  Technology services and other revenue also included the
        consolidated revenue from Razor Risk effective from February
        14, 2012.
    --  The increase in technology services and other revenue also
        included net foreign exchange gains on U.S. dollar accounts
        receivable in Q4/12 whereas we recorded net foreign exchange
        losses in Q4/11.
    --  These increases were somewhat offset by the loss in revenue
        from IIROC following the termination of our contract to provide
        services effective March 31, 2012, which amounts to
        approximately $6.7 million on an annual basis. In addition,
        revenue from prior periods included revenue related to services
        provided to CDS which have been eliminated upon consolidation
        effective August 1, 2012. This revenue from CDS was
        approximately $0.4 million in Q4/11.

    --  On February 21, 2012, CDCC launched the clearing of fixed
        income REPO agreements. The interest income and interest
        expense arising from the REPO agreements are equal. However, as
        CDCC does not have a legal right to offset these amounts, they
        are recognized separately on the consolidated income statement.
    --  In Q4/12, CDCC cleared 8,337 REPO transactions, comprised of 99
        eligible ISINs with a notional value of $368.1 billion.
    --  Fees earned by CDCC for providing the clearing service for the
        REPO agreements are included in Derivatives Markets Trading,
        clearing and related revenue.

Operating Expenses

Operating expenses in Q4/12 were $105.3 million(a), up $24.7 million, or 31%, 
from $80.6 million(b) due to the additional operating expenses included from 
acquisitions. These included $16.7 million of expenses from CDS and $3.8 
million of expenses from Alpha. There was also an increase related to the 
incremental amortization of intangible assets related to TMX Group Limited's 
acquisitions of TMX Group Inc., CDS and Alpha of $9.8 million. In addition, 
the increase was attributable to the inclusion of an aggregate of $3.1 million 
of incremental expenses related to Razor Risk, consolidated from February 14, 
2012 and ir2020, the assets of which were acquired December 23, 2011. These 
increases were partially offset by lower costs associated with short-term and 
long-term employee performance incentive plans and higher capitalization of 
costs associated with technology initiatives.

Compensation and Benefits

  $42.1        $40.1          $2.0             5%
    --  Compensation and benefits costs were higher due to an overall
        increase in salary and benefits costs relating to increased
        headcount primarily from acquisitions and merit increases,
        including $7.6 million of costs related to CDS and $0.9 million
        of costs related to Alpha, as well as costs related to Razor
        Risk and ir2020. There were 1,310 TMX Group Limited employees
        at December 31, 2012 versus 906 employees for TMX Group Inc.
        and its subsidiaries at December 31, 2011 largely due to the
        net additions of CDS (319) and Alpha (40), Razor Risk (36) and
        ir2020 (4). In addition, there were 79 contractors for TMX
        Group Limited at December 31, 2012 versus 51 contractors for
        TMX Group Inc. at December 31, 2011 primarily due to the
        additions of 25 CDS contractors. We continue to invest in our
        leading technologies, and over the past year we have continued
        to add resources to generate future revenue growth. For
        example, there have been 10 new employees engaged in the REPO
        initiative since Q2/11.
    --  Largely offsetting the increases, there were lower costs
        associated with short-term and long-term employee performance
        incentive plans and higher capitalization of costs associated
        with technology initiatives.

Information and Trading Systems

  $20.1        $15.1          $5.0            33%
    --  Information and trading systems expenses were higher primarily
        due to the inclusion of $4.3 million of expenses from CDS and
        $2.4 million of expenses from Alpha.
    --  The increase was offset by reduced spending on projects,
        including corporate software conversions, enterprise expansion
        and pre-trade risk management along with other operational
        savings.

  $23.5        $18.2          $5.3            29%
    --  The increase in general and administration costs was primarily
        due to the inclusion of $3.7 million of expenses from CDS and
        $0.4 million of expenses from Alpha, as well as costs related
        to Razor Risk. In addition, we incurred bank fees relating to
        the REPO initiative, almost all of which have been charged back
        to the Clearing Members on a pro rated basis based on service
        usage, and are included in Derivatives Markets Trading,
        clearing and related revenue.
    --  These increases were partially offset by lower net BOX expenses
        due to the establishment of the BOX SRO entity and collection
        of fines. Also, there was a reduction in marketing and bad debt
        expenses compared with Q4/11.

  $19.6         $7.2         $12.4           172%
    --  Depreciation and amortization costs increased by $9.8 million
        due to the amortization of intangible assets related to TMX
        Group Limited's acquisitions exclusive of amortization related
        to intangible assets previously held by TMX Group Inc., Alpha
        and CDS. In addition, amortization further increased due to
        $1.0 million in depreciation and amortization costs associated
        with the business operations of CDS.
    --  Depreciation and amortization costs also increased due to
        increased amortization of intangible assets related to REPO
        clearing and acquisitions including Razor Risk and ir2020. In
        addition, there was increased depreciation of fixed assets
        related to co-location services and TMX Quantum XA.

    $1.9         $1.5          $0.4            27%
    --  MX holds a 53.8% ownership interest in BOX. The results for BOX
        are consolidated in our Income Statement.
    --  Net income attributable to non-controlling interests represents
        the other BOX members' share of BOX's net income or loss in the
        period. The increase in net income in Q4/12 from Q4/11
        reflected an accounting adjustment relating to the BOX SRO.

Supplementary Information

The table below contains TMX Group Limited consolidated revenue and operating 
expenses, income from operations and net income attributable to 
non-controlling interests which include the accounts of TMX Group Limited and 
the operating results of TMX Group Inc. and its subsidiaries for the period 
from January 1, 2012 to December 31, 2012, and the operating results of CDS 
and Alpha and their subsidiaries for the period from August 1 to December 31, 
2012. In order to provide a meaningful discussion of the results of operations 
in this press release, we have compared TMX Group Limited information for 2012 
with TMX Group Inc. information for January 1, 2011 to December 31, 2011. This 
approach is similar to how the results would be reported if TMX Group Inc. was 
the acquirer of CDS and Alpha.

This information differs from the TMX Group Limited consolidated financial 
statements for the year ended December 31, 2012. The TMX Group Limited 
consolidated financial statements reflect the accounts of TMX Group Limited 
for the year ended December 31, 2012, including the operating results of TMX 
Group Inc., Alpha, CDS and their respective subsidiaries from August 1, 2012,

Revenue

Revenue was $673.1 million for 2012, down $0.4 million compared with $673.5 
million for 2011, reflecting lower revenue from issuer services and cash 
markets trading. These decreases were largely offset by the inclusion of $37.1 
million of revenue from CDS and $7.9 million of revenue from Alpha, effective 
August 1, 2012, and increased revenue from information services (including 
revenue from TMX Atrium, acquired July 29, 2011), derivatives trading and 
clearing and technology services and other.

    --  Initial listing fees in 2012 were lower primarily due to a 34%
        decrease in the number of new listings on Toronto Stock
        Exchange (132 in 2012 compared with 199 in 2011) and a 25%
        decrease in the number of new listings on TSX Venture Exchange
        (161 in 2012 compared with 216 in 2011). Initial listing fees
        on Toronto Stock Exchange in 2011 included approximately $2.8
        million of revenue as a result of a large number of issuers
        converting from income trusts to corporate entities in the
        period.
    --  Additional listing fees in 2012 on both exchanges decreased
        compared with 2011 with the majority coming from the TSX
        Venture Exchange. The decreases on both exchanges were
        primarily due to the lower number of total transactions in 2012
        (both financing related transactions and non financing
        activities). 
    --  Issuers listed on Toronto Stock Exchange and TSX Venture
        Exchange pay annual sustaining listing fees primarily based on
        their market capitalization at the end of the prior calendar
        year, subject to minimum and maximum fees. The decrease in
        sustaining listing fees was due to the overall lower market
        capitalization of listed issuers on both exchanges (combined
        $2,051.1 billion at the end of 2011 compared with $2,278.1
        billion at the end of 2010). The decrease was also due to a
        reduction in certain fees effective January 1, 2012.
    --  Other issuer services revenue included $1.1 million of revenue
        from CDS Solutions effective August 1, 2012 and higher revenue
        from Equicom, which provides investor relations and corporate
        communications services.

(f) TMX Group Inc. results for January 1, 2011 to December 31, 2011.

Cash Markets
    --  Cash markets equity trading revenue decreased primarily due to
        a 20% decrease in the volume of securities traded on Toronto
        Stock Exchange (82.5 billion securities in 2012 versus 103.6
        billion securities traded in 2011) and a 33% decrease in the
        volume of securities traded on TSX Venture Exchange (43.6
        billion securities in 2012 versus 65.0 billion securities in
        2011). Cash markets revenue also included revenue from TMX
        Select, which was launched in July 2011 (2.3 billion securities
        traded in 2012 versus 1.2 billion in 2011).
    --  The decrease was also as a result of changes to our equity
        trading fee schedule effective March 1, 2011, which reduced the
        fees for significant usage for our Market on Open (MOO)
        facility and introduced net credit payments for trading in our
        continuous limit order book as well as additional changes
        effective April 1, 2011, which provided cost savings to
        participants that trade equities where the trade price per
        security is lower than $1.00. Effective October 1, 2011, we
        also made changes to our market making fee schedule for Toronto
        Stock Exchange, including introducing monthly credits.
    --  Partially offsetting the decrease was the inclusion of $6.4
        million of revenue from CDS clearing and settlement effective
        August 1, 2012. CDS processed 126.6 million exchange trades and
        7.1 million non-exchange/OTC trades from August 1, 2012 to
        December 31, 2012.
    --  The decrease was also partially offset by the inclusion of $3.5
        million of revenue from Alpha effective August 1, 2012. There
        were 12.0 billion securities traded on Alpha from August 1,
        2012 through December 31, 2012.

CDS Depository
    --  CDS Depository revenue of $20.6 million is included from August
        1, 2012. CDS held a daily average of approximately 321,000
        equities positions with an average of 276.0 billion shares and
        a daily average of 180,000 debt positions with an average par
        value of $2.3 trillion on deposit from August 1, 2012 to
        December 31, 2012.

Derivatives Markets
    --  The increase in derivatives markets revenue reflects an
        increase in trading and clearing revenue from MX and CDCC.
        Volumes increased by 4% (64.4 million contracts traded in 2012
        versus 62.0 million contracts traded in 2011) largely as a
        result of increased volumes in the Ten-Year Government of
        Canada Bond Futures, or CGB contract, as well as increased
        volumes in ETF options. The increase in revenue was partially
        offset by the impact of price changes since 2011. Open interest
        was down 7% at December 31, 2012 compared with December 31,
        2011.
    --  Derivatives markets revenue for 2012 also includes fees earned
        by CDCC for providing the clearing service on REPO transactions
        as well as bank fees that are charged back to Clearing Members
        (see Other Credit and Liquidity Facilities and Guarantee). This
        service was launched on February 21, 2012.
    --  The increase in derivatives markets revenue also reflects a 4%
        increase in BOX volumes (145.0 million contracts in 2012 versus
        139.7 million contracts traded in 2011) and the impact of the
        depreciation of the Canadian dollar against the U.S. dollar in
        2012 compared with 2011.
    --  The increase in derivatives markets revenue was partially
        offset by lower BOX revenue from Options Regulatory Fees. As of
        May 14, 2012, the fees charged, and related costs incurred, by
        the BOX SRO entity are not consolidated into TMX Group results.

Energy Markets
    --  There was an 8% decrease in total energy volume(#) traded on
        NGX in 2012 (14.3 million terajoules in 2012 compared to 15.5
        million terajoules in 2011) primarily due to a 9% decrease in
        natural gas volumes.
    --  There was a 79% decline in NGX crude oil volumes (previously
        NetThruPut Inc.'s, or NTP's, business) due to limited
        acceptance of NGX's crude oil clearing services and increased
        competition from voice brokers, including from Shorcan Energy
        Brokers. This decrease in NGX crude oil revenue was essentially
        offset by higher revenue from Shorcan Energy Brokers driven by
        higher volumes in 2012 compared with 2011. TMX Group Inc.
        recorded a non-cash impairment charge on the intangible assets
        related to NTP in Q2/12.
    --  The decrease in revenue was largely offset as a result of NGX
        having deferred less revenue in 2012, on a net basis, than in
        2011 due to a decreased level of forward contracts.
    --  The decrease in revenue was somewhat offset by the impact of
        the depreciation of the Canadian dollar against the U.S. dollar
        in 2012 compared with 2011.

$179.3      $165.1         $14.2             9%
    --  The increase was partially due to the inclusion of $4.4 million
        of revenue from Alpha and $2.5 million of revenue from CDS,
        effective August 1, 2012. Revenue from TMX Atrium, which was
        acquired July 29, 2011, has also grown, partially offset by the
        depreciation of the Euro against the Canadian dollar in 2012
        compared with the period following acquisition in 2011. The
        increase was also due to revenue from co-location services,
        data feeds and PC-Bond and higher revenue recoveries related to
        under-reported usage of real-time quotes in prior periods
        during 2012 compared with 2011. There was also an 8% increase
        in the average number of MX market data subscriptions (27,748.6
        (+) MX market data subscriptions in 2012 compared with 25,769.7
        (+) in 2011) and a price increase effective April 1, 2012
        related to data feeds.
    --  The increase in revenue was also attributable to the impact of
        the depreciation of the Canadian dollar against the U.S. dollar
        in 2012 compared with 2011.
    --  The increases were partially offset by net price reductions on
        TSX market data subscriptions effective October 1, 2011 and
        April 1, 2012, and lower revenue from usage based quotes.
    --  Overall, there was a 5% decrease in the average number of
        professional and equivalent real-time market data subscriptions
        to Toronto Stock Exchange and TSX Venture Exchange products
        (151,799(+) professional and equivalent real-time market data
        subscriptions in 2012 compared with 160,436(+) in 2011).

    --  Technology services and other revenue includes $6.8 million of
        revenue from CDS services relating largely to SEDAR, SEDI and
        NRD effective August 1, 2012. The current contract is due to
        expire on October 31, 2013 and a new service provider is being
        secured to take over these services. We do not expect the
        operating agreements to be renewed beyond October 31, 2013. Any
        expenses associated with the wind down of the business
        operations have not been recorded in the consolidated income
        statement. Only a portion of the ongoing costs associated with
        this revenue will be fully eliminated.
    --  In addition, we consolidated revenue from Razor Risk, effective
        from February 14, 2012.
    --  Technology services and other revenue increased primarily due
        to receipt of a one-time termination fee, recovery of disposal
        and severance costs, and recognition of previously deferred
        revenue from IIROC of approximately $5.0 million.
    --  Offsetting these increases in revenue was the loss in revenue
        from IIROC following the termination of our contract to provide
        services effective March 31, 2012, which amounts to
        approximately $6.7 million on an annual basis. In addition,
        revenue from prior periods included revenue related to services
        provided to CDS which have been eliminated upon consolidation
        effective August 1, 2012. This revenue from CDS was
        approximately $1.7 million in 2011.
    --  In addition, we recorded net foreign exchange losses on U.S.
        dollar accounts receivable in 2012 whereas we recorded net
        foreign exchange gains in 2011.

    --  On February 21, 2012, CDCC launched the clearing of fixed
        income REPO agreements. The interest income and interest
        expense arising from the REPO agreements are equal. However, as
        CDCC does not have a legal right to offset these amounts, they
        are recognized separately on the consolidated income statement.
    --  From February 21, 2012 through December 31, 2012, CDCC cleared
        20,556 REPO transactions, comprised of 131 eligible ISINs with
        a notional value of $919.1 billion.
    --  Fees earned by CDCC for providing the clearing service for the
        REPO agreements are included in Derivatives Markets Trading,
        clearing and related revenue.

Operating Expenses

Operating expenses in 2012 were $370.7 million, up $69.2 million, or 23%, from 
$301.5 million in 2011 primarily due to the inclusion of $29.9 million of 
expenses from CDS and $6.7 million of expenses from Alpha, effective August 1, 
2012. There was also an increase of $16.6 million related to the incremental 
amortization of intangible assets related to TMX Group Limited's acquisition 
of TMX Group Inc., CDS and Alpha. In addition, the increase was attributable 
to the inclusion of an aggregate of $19.2 million of incremental expenses 
related to TMX Atrium, acquired July 29, 2011, Razor Risk, consolidated from 
February 14, 2012 and ir2020, the assets of which were acquired on December 
23, 2011. There was also an overall increase in salary and benefits costs, 
information and trading systems costs and depreciation and amortization, 
somewhat offset by lower general and administration costs due to the inclusion 
in 2011 of a commodity tax adjustment of $4.8 million relating to prior 
periods.

$167.4      $147.9         $19.5            13%
    --  Compensation and benefits costs were higher due to an overall
        increase in salary and benefits costs relating to increased
        headcount primarily from acquisitions and merit increases,
        including $14.5 million of costs related to CDS and $2.2
        million of costs related to Alpha, as well as costs related to
        TMX Atrium, Razor Risk and ir2020. There were 1,310 TMX Group
        Limited employees at December 31, 2012 versus 906 employees for
        TMX Group Inc. and its subsidiaries at December 31, 2011
        largely due to the net additions of CDS (319) and Alpha (40),
        Razor Risk (36) and ir2020 (4). In addition, there were 79
        contractors for TMX Group Limited at December 31, 2012 versus
        51 contractors for TMX Group Inc. at December 31, 2011
        primarily due to the additions of 25 CDS contractors. We
        continue to invest in our leading technologies, and over the
        past year we have continued to add resources to generate future
        revenue growth. For example, there have been 10 new employees
        engaged in the REPO initiative since Q2/11.
    --  There was also an increase in costs associated with long-term
        employee performance incentive plans due to share price
        appreciation.
    --  The higher costs were partially offset by higher capitalization
        of costs associated with technology initiatives and lower costs
        associated with short-term employee performance incentive
        plans.

 $66.5       $49.8         $16.7            34%
    --  Information and trading systems expenses were higher primarily
        due to the inclusion of $7.4 million of expenses from CDS and
        $3.6 million of expenses from Alpha, as well as expenses
        related to TMX Atrium and Razor Risk.
    --  The increase was also due to higher spending on new technology
        initiatives in 2012 compared with 2011. We invested in a number
        of new projects, including TMX Quantum XA. These increases were
        partially offset by other operational savings, including lower
        NGX fees paid to ICE due to lower natural gas volumes in the
        U.S.

 $83.8       $75.7          $8.1            11%
    --  The increase in general and administration costs was due to the
        inclusion of $6.5 million of expenses from CDS and $0.9 million
        of expenses from Alpha, as well as costs related to TMX Atrium
        and Razor Risk.
    --  In addition, we incurred bank fees relating to the REPO
        initiative, almost all of which have been charged back to the
        Clearing Members on a pro rated basis based on service usage,
        and are included in Derivatives Markets Trading, clearing and
        related revenue.
    --  Somewhat offsetting these increases, general and administration
        costs in 2011 included a commodity tax adjustment of $4.8
        million relating to prior periods. We also incurred lower bad
        debt expenses and lower marketing costs in 2012 compared with
        2011. Also offsetting these increases were lower net BOX
        expenses due to the establishment of the BOX SRO entity and
        collection of fines.

Depreciation and Amortization

(in millions of dollars)

2012(e) 2011(f) $ increase % increase

 $53.0   $28.1     $24.9        89%
    --  Depreciation and amortization costs increased by $16.6 million
        due to the incremental amortization of intangible assets
        related to TMX Group Limited's acquisition of TMX Group Inc.,
        Alpha and CDS, exclusive of amortization related to intangible
        assets previously held by TMX Group Inc., Alpha and CDS.  In
        addition, amortization further increased due to $1.9 million in
        depreciation and amortization costs associated with the
        business operations of CDS.
    --  Depreciation and amortization costs also increased due to
        increased amortization of intangible assets related to REPO
        clearing and acquisitions including TMX Atrium, Razor Risk,
        ir2020 and the Equicom portal. In addition, there was increased
        depreciation of fixed assets related to co-location services,
        and TMX Quantum XA.

TMX Group Inc.
    --  The net income attributable to non-controlling interests
        includes $3.5 million related to the period prior to September
        14, 2012, when TMX Group Limited owned 80% of TMX Group Inc.
        TMX Group Limited owned 80% of TMX Group Inc., from July 31,
        2012 to September 13, 2012.

BOX
    --  MX holds a 53.8% ownership interest in BOX. The results for BOX
        are consolidated in our Income Statement.
    --  The net income attributable to non-controlling interests
        includes $11.9 million related to BOX, an increase of $5.8
        million from $6.1 million for 2011.
    --  Net income attributable to non-controlling interests represents
        the other BOX members' share of BOX's net income or loss in the
        period. The increase reflects the non-controlling interests'
        share of a non-cash reversal of an impairment loss on the
        intangible asset related to BOX in Q2/12, which was $6.2
        million. In addition, the increase in net income for 2012 over
        2011 reflected higher revenue due to an increase in volumes and
        an accounting adjustment relating to the BOX SRO.

As at December 31, 2012, all covenants were met.
    --  Certain of our material operating subsidiaries have entered
        into a guarantee agreement with regards to the Credit Agreement
        whereby they jointly and severally guarantee payment of all of

Other Credit Facilities and Guarantee

To backstop its clearing operations, NGX currently has a credit agreement in 
place with a Canadian Schedule I bank which includes a US$100.0 million 
clearing backstop fund. TMX Group Inc. is NGX's unsecured guarantor for this 
fund up to a maximum of US$100.0 million. This facility had not been drawn 
upon at December 31, 2012.

NGX also has an Electronic Funds Transfer (EFT) Daylight facility of $300.0 
million in place with a Canadian Schedule I bank.

CDCC maintains daylight liquidity facilities for a total of $700.0 million to 
provide liquidity on the basis of collateral in the form of securities that 
have been received by CDCC. The daylight liquidity facilities must be cleared 
to zero at the end of each day.

CDCC also maintains a $100.0 million syndicated revolving standby liquidity 
facility to provide end of day liquidity in the event that CDCC is unable to 
clear the daylight liquidity facilities to zero. Advances under the facility 
will be secured by collateral in the form of securities that have been pledged 
to or received by CDCC. In Q3/12, CDCC drew on this facility to cover a failed 
REPO settlement. The balance was settled and the facility was repaid the next 
day.

CDCC maintains a $4,800.0 million repurchase facility with a syndicate of 6 
Canadian Schedule 1 chartered banks. This facility is comprised of $1,200.0 
million in committed liquidity and $3,600.0 million in uncommitted liquidity 
and is in place to provide end of day liquidity in the event that CDCC is 
unable to clear the daylight liquidity facilities to zero. The facility will 
provide liquidity in exchange for securities that have been pledged to or 
received by CDCC.

In addition, CDCC has signed an agreement that would allow the Bank of Canada 
to provide emergency last-resort liquidity to CDCC at the discretion of the 
Bank of Canada. This liquidity facility is intended to provide end of day 
liquidity only in the event that CDCC is unable to access liquidity from the 
revolving standby liquidity facility and the syndicated REPO facility or in 
the event that the liquidity under such facilities is insufficient. Use of 
this facility would be on a fully collateralized basis.

CDS maintains unsecured operating demand loans totalling $11.0 million to 
support short-term operating requirements. To support processing and 
settlement activities of participants, an unsecured overdraft facility and 
demand loan of $15.0 million and an overnight facility of US$5.5 million are 
available. The borrowing rates for these facilities are the Canadian prime or 
the U.S. base rate, depending on the currency drawn. No amounts were drawn on 
these credit facilities as at December 31, 2012.

CDS maintains a US$200.0 million or Canadian dollar equivalent secured standby 
credit arrangement that can be drawn in either U.S. or Canadian currencies. 
This arrangement is available to support processing and settlement activities 
in the event of a participant default. Borrowings under the secured facility 
are obtained by pledging or providing collateral pledged by participants 
primarily in the form of debt instruments issued or guaranteed by federal, 
provincial and/or municipal governments in Canada or U.S. treasury 
instruments. Depending upon the currency drawn, the borrowing rate for the 
secured standby credit arrangement is the U.S. base rate or the Canadian prime 
rate. No amounts were drawn on these credit facilities as at December 31, 2012.

In addition, CDS has signed agreements that would allow the Bank of Canada to 
provide emergency last-resort liquidity to CDS at the discretion of the Bank 
of Canada. This liquidity facility is intended to provide end of day liquidity 
for payment obligations arising from CDSX, and only in the event that CDS is 
unable to access liquidity from its standby liquidity facility or in the event 
that the liquidity under such facilities is insufficient. Use of this facility 
would be on a fully collateralized basis.

    --  Cash Flows used in Operating Activities included $105.0 million
        of Maple Transaction and Integration costs.
    --  In 2012, Cash Flows from Financing Activities included $2,078.7
        million due to the issuance of common shares in connection with
        the Maple Transaction and $1,449.9 million related to the
        establishment of a new credit facility (see Loans payable)
        offset by the repayment of $430.0 million of TMX Group Inc.'s
        debt.
    --  Cash Flows used in Investing Activities included $2,677.1
        million due to TMX Group Limited's acquisitions of TMX Group
        Inc., Alpha and CDS, net of cash acquired.

Summary of Cash Position and Other Matters(1)

We had $313.4 million of cash and cash equivalents and marketable securities 
at December 31, 2012. From August through December 2012, following the 
acquisitions of TMX Group Inc., CDS and Alpha, we earned operating income of 
$115.4 million. For the year ended December 31, 2012, cash flows used in 
operations were $76.1 million, net of $105.0 million of cash outlays 
pertaining to the Maple Transaction. We paid $29.9 million in dividends on TMX 
Group Inc. common shares and $21.5 million in dividends on TMX Group Limited 
common shares in 2012. Based on our current business operations and model, we 
believe that we have sufficient cash resources to operate our business, and 
meet our financial covenants under the Credit Agreement and our capital 
maintenance requirements imposed by regulators.

Debt financing of future investment opportunities could be limited by current 
and future economic conditions, the covenants on TMX Group's Credit Agreement, 
and by capital maintenance requirements imposed by regulators.

The recognition orders of TSX Inc. and Alpha Exchange contain certain 
financial viability tests that must be met. If either TSX Inc. or Alpha 
Exchange Inc. fails to maintain or anticipates that it will fail any of its 
financial viability tests, the OSC can impose additional terms and conditions. 
This could, for example, include a requirement that TSX Inc. or Alpha Exchange 
Inc. may not without the prior approval of the Director of the OSC, pay 
dividends (among other things) until the deficiencies have been eliminated for 
at least six months or a shorter period of time as agreed by OSC staff. In 
addition, the recognition order of MX imposes similar restrictions on the 
payment of dividends. If MX fails to meet the financial viability ratios for 
more than three months, MX will not, without the prior approval of Quebec's 
AMF, pay dividends (among other things) until the deficiencies have been 
eliminated for at least six months.

As at December 31, 2012, we met all of the above requirements.

certain forward-looking statements. Please refer to "Caution Regarding 
Forward-Looking Information" for a discussion of risks and uncertainties 
related to such statements.

Supplementary Cash Flow Information For The Quarter And Year Ended December 
31, 2012 Compared With The Quarter And Year Ended December 31, 2011

The tables below contain combined TMX Group Limited summary cash flow 
information which includes the accounts of TMX Group Limited and the cash flow 
information for TMX Group Inc. and it subsidiaries for the period from January 
1, 2012 to December 31, 2012 and the cash flow information for CDS and Alpha 
and their subsidiaries for the period from August 1 to December 31, 2012. In 
order to provide a meaningful discussion of the cash flow information in this 
press release, we have compared TMX Group Limited information for Q4/12 and 
2012 with TMX Group Inc. information of Q4/11 and 2011. This approach is 
similar to how the results would be reported if TMX Group Inc. was the 
acquirer of CDS and Alpha.

This information differs from the TMX Group Limited consolidated financial 
statements for the year ended December 31, 2012. The TMX Group Limited 
consolidated financial statements reflect the accounts of TMX Group Limited 
for the year ended December 31, 2012, including the cash flow information for 
TMX Group Inc., Alpha, CDS and their respective subsidiaries from August 1, 
2012, and only the accounts of TMX Group Limited for the comparative period of 
the year ended December 31, 2011.

TMX Group Limited was formed solely for the purpose of pursuing the Maple 
Acquisition along with the CDS and Alpha Acquisitions. Prior to the completion 
of the CDS and Alpha Acquisitions on August 1, 2012 and TMX Group's take up of 
80% of the common shares of TMX Group Inc. on July 31, 2012 under the Maple 
Offer it had no material assets and no history of earnings and had not 
commenced commercial operations.

    --  Cash Flows from Operating Activities were $41.3 million lower

        in Q4/12 compared with Q4/11 primarily due to a net increase in

    --  Cash Flows from Operating Activities were $53.3 million in
        2012, a decrease of $250.2 million primarily due to $130.5
        million in Maple Transaction related cash outlays and $32.8
        million of interest paid related to these acquisitions and TMX
        Group Inc.'s $430.0 million of debt.
    --  Cash Flows from Financing Activities were $2,984.9 million in
        2012, an increase of $3,098.8 million primarily due to the
        inclusion of $2,078.7 million related to the issuance of common
        shares in connection with the Maple Transaction and $1,449.9
        million related to the establishment of a new credit facility
        (see Loans payable) offset by the repayment of $430.0 million
        of TMX Group Inc.'s debt.
    --  Cash Flows (used in) Investing Activities were $2,383.7 million
        in 2012, an increase of $2,211.2 million largely due to the
        inclusion of $2,677.1 million from TMX Group Limited's
        acquisitions of TMX Group Inc., Alpha and CDS, net of cash
        acquired.

Caution Regarding Forward-Looking Information

This press release of TMX Group contains "forward-looking information" (as 
defined in applicable Canadian securities legislation) that is based on 
expectations, assumptions, estimates, projections and other factors that 
management believes to be relevant as of the date of this press release. 
Often, but not always, such forward-looking information can be identified by 
the use of forward-looking words such as "plans", "expects", "is expected", 
"budget", "scheduled", "targeted", "estimates", "forecasts", "intends", 
"anticipates", "believes", or variations or the negatives of such words and 
phrases or statements that certain actions, events or results "may", "could", 
"would", "might" or "will" be taken, occur or be achieved or not be taken, 
occur or be achieved. Forward-looking information, by its nature, requires us 
to make assumptions and is subject to significant risks and uncertainties 
which may give rise to the possibility that our expectations or conclusions 
will not prove to be accurate and that our assumptions may not be correct.

Examples of such forward-looking information in this press release include, 
but are not limited to, factors relating to stock, derivatives and energy 
exchanges and clearing houses and the business, strategic goals and 
priorities, market condition, pricing, proposed technology and other 
initiatives, financial condition, operations and prospects of TMX Group, the 
intention to integrate the business of TMX Group Inc. with CDS and Alpha and 
the anticipated benefits and synergies from the CDS and Alpha Acquisitions 
which are subject to significant risks and uncertainties. These risks include: 
competition from other exchanges or marketplaces, including alternative 
trading systems and new technologies, on a national and international basis; 
dependence on the economy of Canada; adverse effects on our results caused by 
global economic uncertainties including changes in business cycles that impact 
our sector; failure to retain and attract qualified personnel; geopolitical 
and other factors which could cause business interruption; dependence on 
information technology; vulnerability of our networks and third party service 
providers to security risks; failure to implement our strategies; regulatory 
constraints; risks of litigation or regulatory proceedings; dependence on 
adequate numbers of customers; failure to develop, market or gain acceptance 
of new products; currency risk; adverse effect of new business activities; not 
being able to meet cash requirements because of our holding company structure 
and restrictions on paying dividends; dependence on third party suppliers 
and service providers; dependence of trading operations on a small number of 
clients; risks associated with our clearing operations; challenges related to 
international expansion; restrictions on ownership of TMX Group common shares; 
inability to protect our intellectual property; adverse effect of a systemic 
market event on certain of our businesses; risks associated with the credit of 
customers; cost structures being largely fixed; dependence on market activity 
that cannot be controlled; the inability to successfully integrate TMX Group 
Inc.'s operations with those of Alpha and CDS including, without limitation 
incurring and/or experiencing unanticipated costs and/or delays or 
difficulties; inability to reduce headcount, eliminate or consolidate 
contracts, technology, physical accommodations or other operating expenses, 
and the failure to realize the anticipated benefits from the acquisitions of 
TMX Group Inc., Alpha and CDS, including the fact that synergies are not 
realized in the amount or the time frame anticipated or at all; the regulatory 
constraints that apply to the business of TMX Group and its regulated 
subsidiaries, costs of on exchange clearing and depository services, trading 
volumes (which could be higher or lower than estimated) and revenues; future 
levels of revenues being lower than expected or costs being higher than 
expected.

The forward-looking information contained in this press release is presented 
for the purpose of assisting readers of this document in understanding our 
financial condition and results of operations and our strategies, priorities 
and objectives and may not be appropriate for other purposes. The 
forward-looking information relating to targeted cost synergies is being 
provided to help demonstrate the benefits of the CDS and Alpha Acquisitions, 
but readers are cautioned that such information may not be appropriate for 
other purposes. Actual results, events, performances, achievements and 
developments are likely to differ, and may differ materially, from those 
expressed or implied by the forward-looking information contained in this 
press release.

Such forward-looking information is based on a number of assumptions which may 
prove to be incorrect, including, but not limited to, assumptions in 
connection with the ability of TMX Group to successfully compete against 
global and regional marketplaces; business and economic conditions generally; 
exchange rates (including estimates of the U.S. dollar - Canadian dollar 
exchange rate), the level of trading and activity on markets, and particularly 
the level of trading in TMX Group's key products; business development and 
marketing and sales activity; the continued availability of financing on 
appropriate terms for future projects; productivity at TMX Group, as well as 
that of TMX Group's competitors; market competition; research & development 
activities; the successful introduction and client acceptance of new products; 
successful introduction of various technology assets and capabilities; the 
impact on TMX Group and its customers of various regulations; TMX Group's 
ongoing relations with its employees; and the extent of any labour, equipment 
or other disruptions at any of its operations of any significance other than 
any planned maintenance or similar shutdowns.

While we anticipate that subsequent events and developments may cause our 
views to change, we have no intention to update this forward-looking 
information, except as required by applicable securities law. This 
forward-looking information should not be relied upon as representing our 
views as of any date subsequent to the date of this press release. We have 
attempted to identify important factors that could cause actual actions, 
events or results to differ materially from those current expectations 
described in forward-looking information. However, there may be other factors 
that cause actions, events or results not to be as anticipated, estimated or 
intended and that could cause actual actions, events or results to differ 
materially from current expectations. There can be no assurance that 
forward-looking information will prove to be accurate, as actual results and 
future events could differ materially from those anticipated in such 
statements. Accordingly, readers should not place undue reliance on 
forward-looking information. These factors are not intended to represent a 
complete list of the factors that could affect us. A description of the 
above-mentioned items is contained in our 2012 MD&A under the heading Risks 
and Uncertainties.
