TransCanada Reports Strong Second Quarter 2015 Financial Results

2015-07-31 07:00 ET - News Release

CALGARY, ALBERTA -- (Marketwired) -- 07/31/15

TransCanada Corporation (TSX:TRP) (NYSE:TRP) (TransCanada) today announced net income attributable to common shares for second quarter 2015 of $429 million or $0.60 per share compared to $416 million or $0.59 per share for the same period in 2014. Comparable earnings for second quarter 2015 were $397 million or $0.56 per share compared to $332 million or $0.47 per share for the same period last year. TransCanada's Board of Directors also declared a quarterly dividend of $0.52 per common share for the quarter ending September 30, 2015, equivalent to $2.08 per common share on an annualized basis.

"Our three core businesses produced another solid quarter of financial results demonstrating the resiliency of our high-quality asset base in challenging market conditions," said Russ Girling, TransCanada's president and chief executive officer. "Comparable earnings and funds generated from operations increased 20 and 16 per cent, respectively, compared to the same period last year highlighting the strong foundation that will allow us to continue to grow the dividend at an annual rate of eight to ten per cent through 2017 and fund our industry-leading $46 billion capital program."

Over the past several months, we advanced key components of our growth plans which included more than $13 billion in proposed natural gas pipeline projects to support the emerging liquefied natural gas (LNG) industry on the British Columbia (B.C.) Coast. Our Prince Rupert Gas Transmission (PRGT) project reached an important milestone with a positive Final Investment Decision (FID), subject to two conditions, from Pacific NorthWest LNG (PNW LNG). We also received the majority of the facilities permits for both our PRGT and Coastal GasLink projects which positions us to be ready to commence construction, pending a FID from the respective project sponsors. PRGT and Coastal GasLink also continued their engagement with Aboriginal groups along the pipeline routes and signed several project agreements with First Nation communities.

We also continue to advance the balance of our $46 billion portfolio of commercially secured projects as well as numerous other growth initiatives. These projects are expected to result in significant growth in earnings, cash flow and dividends through the end of the decade. With our high-quality asset base and financial strength, we remain well positioned to create long-term shareholder value throughout various market conditions.

Net income attributable to common shares increased by $13 million to $429 million or $0.60 per share for the three months ended June 30, 2015 compared to the same period last year. Second quarter 2015 included a $34 million income tax expense adjustment due to an increase in the Alberta corporate income tax rate and an $8 million after-tax restructuring charge related to changes to our major projects group. Second quarter 2014 included a $99 million after-tax gain from the sale of Cancarb and a $31 million after-tax loss from the termination of a natural gas storage contract. Both periods included unrealized gains and losses from changes in risk management activities. All of these specific items are excluded from comparable earnings.

Comparable earnings for second quarter 2015 were $397 million or $0.56 per share compared to $332 million or $0.47 per share for the same period in 2014. Higher earnings from the Canadian Mainline, NGTL System, Keystone, Bruce Power and Eastern Power were partially offset by lower contributions from U.S. Power and Western Power.

Notable recent developments in Natural Gas Pipelines, Liquids Pipelines, Energy and Corporate include:


                                                                            
                                                                            
Natural Gas Pipelines:                                                      

--  NGTL System Expansions: The NGTL System has approximately $6.8 billion
    of new supply and demand facilities currently under development. In
    second quarter 2015, we continued to advance several of these capital
    expansion projects and plan to file additional facilities applications
    for this program through the remainder of 2015. We have received
    additional requests for firm receipt service that we anticipate will
    increase the overall capital spend on the NGTL System beyond the
    previously announced program and continue to work with our customers to
    best match their requirements for 2016, 2017 and 2018 in-service dates.
    
    On April 15, 2015, the National Energy Board (NEB) issued its report
    recommending the federal government approve the NGTL System's $1.7
    billion North Montney Mainline project which will provide substantial
    new capacity on the NGTL System to meet the transportation requirements
    associated with rapidly increasing development of natural gas resources
    in the Montney supply basin in northeastern B.C. The project will
    connect Montney and other Western Canada Sedimentary Basin supply to
    both existing and new natural gas markets, notably emerging markets for
    LNG.
    
    The North Montney Mainline project will consist of two large diameter,
    42-inch pipeline sections, Aitken Creek and Kahta, totaling
    approximately 301 kilometres (km) (187 miles) in length, and associated
    metering facilities, valve sites and compression facilities. The project
    will also include an interconnection with our proposed PRGT project to
    provide natural gas supply to the proposed PNW LNG liquefaction and
    export facility near Prince Rupert, B.C. NGTL currently expects to have
    the Aitken Creek Section in service in late 2016, and the Kahta Section
    in service in 2017.
    
    The Federal Government approved the recommendations of the report from
    the NEB, and on June 11, 2015, the NEB issued a Certificate of Public
    Convenience and Necessity to proceed with the project, subject to
    certain terms and conditions. Under one of these conditions,
    construction on the North Montney Mainline Project can only begin after
    a confirmation of FID has been made on the proposed PNW LNG project and
    we are proceeding with construction on PRGT.
    
    
--  Canadian Mainline: On March 31, 2015, we submitted a compliance toll
    filing in response to direction from the NEB's RH-001-2014 Decision
    issued in November 2014. On June 12, 2015, the NEB approved the applied-
    for compliance tolls, as filed. These final tolls became effective on
    July 1, 2015 which allowed, among other things, the recording of
    incentive earnings as approved by the NEB.
    
    On June 2, 2015, the NEB approved construction of the King's North
    Connection project to expand gas transmission capacity in the greater
    Toronto area and provide shippers with the flexibility to source growing
    supplies of Marcellus gas from the U.S. Northeast. The project is
    expected to cost approximately $220 million and is anticipated to be in-
    service by third quarter 2016.
    
    
--  PRGT: In second quarter 2015, we received six of the eleven pipeline and
    facilities permits from the B.C. Oil and Gas Commission (BC OGC) needed
    to build and operate PRGT. We anticipate decisions on the remaining BC
    OGC permits in third quarter 2015. PRGT is a 900 km (559 mile) natural
    gas pipeline that will deliver gas from the North Montney producing
    region near Fort St. John, B.C. at an interconnect on the NGTL System to
    the proposed PNW LNG facility near Prince Rupert, B.C.
    
    We continued our engagement with Aboriginal groups along the pipeline
    route and during the quarter announced the signing of project agreements
    with Gitanyow First Nation, Kitselas First Nation, Lake Babine Nation,
    Doig River First Nation, Halfway River First Nation and Yekooche First
    Nation.
    
    On June 11, 2015, PNW LNG announced a positive FID for the proposed
    liquefaction and export facility, subject to two conditions. The first
    condition is approval by the Legislative Assembly of B.C. of a Project
    Development Agreement between PNW LNG and the Province of B.C. This
    condition was satisfied in mid-July 2015. The second condition is a
    positive regulatory decision on PNW LNG's environmental assessment by
    the Government of Canada.
    
    Subject to successful completion of the regulatory process for PRGT, we
    remain on target to begin construction following confirmation of a FID
    by PNW LNG. The in-service date for PRGT is estimated to be 2020 but
    will be aligned with PNW LNG's liquefaction facility timeline.
    
    

--  Coastal GasLink: We have received eight of ten pipeline and facilities
    permits from the BC OGC and anticipate receiving the remaining two
    permits in third quarter 2015. We are continuing our engagement with
    Aboriginal groups along the pipeline route and on June 29, 2015 we
    announced the signing of project agreements with Wet'suwet'en First
    Nation, Skin Tyee Nation, Nee-Tahi-Buhn Band, Yekooche First Nation,
    Doig River First Nation and Halfway River First Nation, all of northern
    B.C.
    
    Coastal GasLink is a 670 km (416 mile) natural gas pipeline that will
    deliver gas from the Montney producing region at an expected
    interconnect on the NGTL System near Dawson Creek, B.C. to LNG Canada's
    proposed LNG facility near Kitimat, B.C. The project is subject to
    regulatory approvals and a positive FID.
    
    
--  GTN Drop Down: On April 1, 2015, we closed the sale of our remaining 30
    per cent interest in GTN to our master limited partnership, TC
    PipeLines, LP (the Partnership). The US$457 million sale, which included
    a US$11 million purchase price adjustment, was comprised of US$264
    million in cash, the assumption of US$98 million in proportional GTN
    debt and the issuance of US$95 million of new Class B units to
    TransCanada. The Class B units entitle us to a cash distribution based
    on 30 per cent of GTN's annual cash distribution after certain
    thresholds are achieved, namely 100 per cent of distributions above
    US$20 million in the first five years and 25 per cent of distributions
    above US$20 million in subsequent years.
    
    The drop down of the remaining interest in GTN is part of a systematic
    series of transactions to sell the remainder of TransCanada's U.S.
    natural gas pipeline assets to the Partnership to help us fund our
    capital program.
    
    At June 30, 2015, we held a 28.2 per cent interest in the Partnership. 

                                                                            
                                                                            
Liquids Pipelines:                                                          

--  Energy East Pipeline: On April 2, 2015, we announced that the marine and
    associated tank terminal in Cacouna, Quebec will not be built as a
    result of the recommended reclassification of beluga whales as an
    endangered species. We are currently evaluating other options and
    amendments to the project are expected to be submitted to the NEB in
    fourth quarter 2015. The NEB has continued to process the application in
    the interim. 
    
    The alteration to the project scope and further refinement of the
    project schedule is expected to result in an in-service date of 2020.
    The original $12 billion cost estimate is expected to increase due to
    further scope refinement as we consult with stakeholders and escalation
    of construction costs as the project schedule is refined.
    
    Binding long-term contracts of approximately one million barrels per day
    (Bbl/d) for the 1.1 million Bbl/d pipeline have been secured and
    discussions with shippers continue.
    
    
--  Keystone Pipeline System: In July 2015, the Keystone Pipeline System
    marked the safe delivery of the one billionth barrel of Canadian and
    U.S. crude oil and celebrated the five-year anniversary of the official
    start of oil deliveries for the 4,247 km (2,639 mile) cross-border
    pipeline from Hardisty, Alberta to markets in the American Midwest and
    in 2014 to the U.S. Gulf Coast.
    
    Construction continues on the 77 km (48 mile) Houston Lateral pipeline
    and tank terminal which will extend the Keystone Pipeline System to
    Houston, Texas refineries. The terminal is expected to have initial
    storage capacity for 700,000 barrels of crude oil. The pipeline and
    terminal are expected to be completed in fourth quarter 2015.
    
    On April 14, 2015, we, along with Magellan Midstream Partners L.P.
    (Magellan), announced a joint development agreement to connect our
    Houston Terminal to Magellan's East Houston Terminal. We will own 50 per
    cent of this US$50 million pipeline project which will enhance
    connections to the Houston market for our Keystone Pipeline System.
    Subject to definitive agreements and receipt of necessary permits and
    approvals, the pipeline is expected to be operational in late 2016.
    
    
--  Keystone XL: In January 2015, the Department of State (DOS) re-initiated
    the national interest review and requested the eight federal agencies
    with a role in the review to complete their consideration of whether
    Keystone XL serves the national interest. All of the agency comments
    were submitted.
    
    On February 12, 2015, Nebraska county courts granted temporary
    injunctions that were negotiated between us and landowners' counsel
    which prevent Keystone from proceeding with condemnation cases until the
    underlying constitutional litigation is resolved. A renewed challenge to
    the constitutionality of the statute under which the Governor approved
    the re-route in the state is pending in a Nebraska District Court.
    
    On June 29, 2015, TransCanada sent a letter to the DOS with additional
    evidence demonstrating that Canada is taking strong steps toward
    managing carbon emissions.
    
    The South Dakota Public Utility Commission has scheduled a hearing in
    third quarter 2015 on our request to certify our existing permit
    authority in that state.
    
    The estimated capital cost for Keystone XL is expected to be
    approximately US$8.0 billion. As of June 30, 2015, we have invested
    US$2.4 billion in the project and have also capitalized interest in the
    amount of US$0.4 billion.
    
    
--  Heartland Pipeline and TC Terminals: On May 7, 2015, the Alberta Energy
    Regulator issued a permit for construction of the Heartland Pipeline.
    The in-service date of the project will be aligned to meet market
    requirements for incremental capacity between the Heartland region near
    Edmonton, Alberta and Hardisty, Alberta.
    
    Crude oil prices continue to remain low, prompting many producers to cut
    capital spending and delay oil sands projects in western Canada. In its
    2015 Crude Oil Forecast, Markets and Transportation report, the Canadian
    Association of Petroleum Producers estimated Western Canada Sedimentary
    Basin crude oil production will continue to grow but at a slower pace
    than previously anticipated. Our liquids pipelines projects are
    supported by long-term contracts. However, with the slowing in growth of
    crude oil production, our intra-Alberta projects may experience a
    similar slowing pace of growth to align with customer requirements. 

                                                                            
                                                                            
Energy:                                                                     

--  Alberta Greenhouse Gas (GHG) Emissions: On June 25, 2015, the Alberta
    government announced a renewal and change to the Specified Gas Emitters
    Regulations (SGER) in Alberta. Since 2007 under the SGER, established
    industrial facilities with GHG emissions above a certain threshold are
    required to reduce their emissions by 12 per cent below an average
    intensity baseline and a carbon levy of $15 per tonne is placed on
    emissions above this target. The changed regulations include an increase
    in the emissions reductions target to 15 per cent in 2016 and 20 per
    cent in 2017, along with an increase in the carbon levy to $20 per tonne
    in 2016 and $30 per tonne in 2017. Our Sundance and Sheerness power
    purchase arrangements are subject to this regulation. Our significant
    inventory of carbon offset credits are expected to mitigate the majority
    of these increased costs. The remaining compliance costs are expected to
    be recovered through increased market pricing and contract flow through
    provisions.
    
    
--  Ravenswood: In late May 2015, the 972 megawatt Unit 30 at the Ravenswood
    Generating Station returned to service after a September 2014 unplanned
    outage which resulted from a problem with the generator associated with
    the high pressure turbine. 

                                                                            
                                                                            
Corporate:                                                                  

--  Our Board of Directors declared a quarterly dividend of $0.52 per share
    for the quarter ending September 30, 2015 on TransCanada's outstanding
    common shares. The quarterly amount is equivalent to $2.08 per common
    share on an annualized basis. 
    
    
--  Financing Activities: In May 2015, a newly formed financing trust (the
    Trust) issued US$750 million of 60-year junior subordinated trust notes
    to third party investors with a fixed interest rate of 5.625 per cent
    for the first ten years converting to a floating rate thereafter. The
    notes are callable at par beginning ten years following their issuance.
    All of the proceeds of the issuance by the Trust were loaned to us in
    US$750 million junior subordinated notes at a rate of 5.875 per cent
    which includes a 0.25 per cent administration charge. On a subordinated
    basis, the obligations of the Trust are guaranteed by TransCanada.
    
    In July 2015, we issued $750 million of medium-term notes maturing on
    July 17, 2025 bearing interest at 3.30 per cent.
    
    The net proceeds of these offerings will be used for general corporate
    purposes and to reduce short-term indebtedness which was used to fund a
    portion of our capital program and for general corporate purposes.
    
    

--  Preferred Share Rate Reset and Conversion: In June 2015, Series 3
    shareholders converted 5.5 million of our 14 million outstanding Series
    3 Cumulative Redeemable First Preferred Shares on a one-for-one basis
    into Series 4 floating-rate Cumulative Redeemable First Preferred
    Shares. The rate on the Series 3 Shares was reset and they will now pay
    an annual fixed dividend rate of 2.152 per cent on a quarterly basis for
    the five-year period which began on June 30, 2015. The Series 4 Shares
    will pay a floating quarterly dividend for the same five-year period
    with the rate set for the first quarterly floating rate period (June 30,
    2015 to but excluding September 30, 2015) at 1.945 per cent per annum
    and will be reset every quarter going forward.

NON-GAAP MEASURES

We use the following non-GAAP measures:


--  EBITDA 
--  EBIT 
--  funds generated from operations 
--  comparable earnings 
--  comparable earnings per common share 
--  comparable EBITDA 
--  comparable EBIT 
--  comparable depreciation and amortization 
--  comparable interest expense 
--  comparable interest income and other expense 
--  comparable income tax expense. 

These measures do not have any standardized meaning as prescribed by U.S. GAAP and therefore may not be comparable to similar measures presented by other entities. Please see the Reconciliation of non-GAAP measures section in this MD&A for a reconciliation of the GAAP measures to the non-GAAP measures.

EBITDA and EBIT

We use EBITDA as an approximate measure of our pre-tax operating cash flow. It measures our earnings before deducting financial charges, income tax, depreciation and amortization, net income attributable to non-controlling interests and preferred share dividends, and includes income from equity investments. EBIT measures our earnings from ongoing operations and is a useful measure of our performance and an effective tool for evaluating trends in each segment as it is equivalent to our segmented earnings. It is calculated in the same way as EBITDA, less depreciation and amortization.

Funds generated from operations

Funds generated from operations includes net cash provided by operations before changes in operating working capital. We believe it is a useful measure of our consolidated operating cash flow because it does not include fluctuations from working capital balances, which do not necessarily reflect underlying operations in the same period, and is used to provide a consistent measure of the cash generating performance of our assets. See the Financial condition section for a reconciliation to net cash provided by operations.

Comparable measures

We calculate the comparable measures by adjusting certain GAAP and non-GAAP measures for specific items we believe are significant but not reflective of our underlying operations in the period. These comparable measures are calculated on a consistent basis from period to period and are adjusted for specific items in each period, as applicable.

Our decision not to include a specific item is subjective and made after careful consideration. Specific items may include:


--  certain fair value adjustments relating to risk management activities 
--  income tax refunds and adjustments and changes to enacted rates 
--  gains or losses on sales of assets 
--  legal, contractual and bankruptcy settlements 
--  impact of regulatory or arbitration decisions relating to prior year
    earnings 
--  restructuring costs 
--  write-downs of assets and investments. 

We calculate comparable earnings by excluding the unrealized gains and losses from changes in the fair value of derivatives used to reduce our exposure to certain financial and commodity price risks. These derivatives generally provide effective economic hedges, but do not meet the criteria for hedge accounting. As a result, the changes in fair value are recorded in net income. As these amounts do not accurately reflect the gains and losses that will be realized at settlement, we do not consider them reflective of our underlying operations.

Net income attributable to common shares increased by $13 million for the three months ended June 30, 2015 and decreased by $12 million for the six months ended June 30, 2015 compared to the same periods in 2014. The 2015 results included:


--  a $34 million adjustment to income tax expense due to the enactment of a
    two per cent increase in the Alberta corporate income tax rate in June
    2015 
--  a charge of $8 million after-tax for severance costs primarily as a
    result of the restructuring of our major projects group in response to
    delayed timelines on certain of our major projects, along with a
    continued focus on enhancing the efficiency and effectiveness of our
    operations. 

The six-month 2014 results also included:


--   a gain on sale of Cancarb Limited and its related power generation
    business of $99 million after tax 
--   a net loss resulting from the termination of a contract with Niska Gas
    Storage of $31 million after tax. 

Net income in all periods included unrealized gains and losses from changes in risk management activities which we exclude, along with the above-noted items, to arrive at comparable earnings.

For the three and six months ended June 30, 2015, comparable earnings increased by $65 million and $108 million compared to the same periods in 2014 as discussed below in the reconciliation of net income to comparable earnings.

Comparable earnings increased by $65 million for the three months ended June 30, 2015 compared to the same period in 2014. This was primarily the net effect of:


--  higher earnings from Bruce Power from higher volumes as a result of
    fewer outage days at Bruce A partially offset by lower Bruce B volumes
    due to increased planned outage days 
--  higher uncontracted volumes on the Keystone Pipeline System 
--  higher earnings from Eastern Power due to incremental earnings from
    Ontario solar facilities acquired in the second half of 2014 and higher
    earnings at Cartier Wind 
--  higher earnings from Canadian Pipelines due to incentive earnings
    recorded for the Canadian Mainline and a higher average investment base
    on NGTL partially offset by lower Canadian Mainline ROE 
--  lower earnings from U.S. Power mainly due to the timing of earnings
    recognized on certain contracts in our power marketing business,
    reflecting the different pricing profiles between the power prices we
    charge our customers and the prices we pay for volumes purchased 
--  lower earnings from Western Power as a result of lower realized power
    prices and lower PPA volumes 
--  higher interest expense from new debt issuances and higher foreign
    exchange on interest related to U.S. dollar-denominated debt. 

Comparable earnings increased by $108 million for the six months ended June 30, 2015 compared to the same period in 2014. This was primarily the net effect of:


--  higher uncontracted volumes on the Keystone Pipeline System 
--  higher earnings from Eastern Power due to the sale of unused natural gas
    transportation, higher contractual earnings at Becancour and incremental
    earnings from Ontario solar facilities acquired in the second half of
    2014 
--  higher earnings from Bruce Power from increased volumes as a result of
    fewer outage days at Bruce A, partially offset by lower Bruce B volumes
    due to increased planned outage days 
--  higher earnings from U.S. and International Pipelines due to increased
    earnings from the Tamazunchale Extension which was placed in service in
    2014, higher ANR Southeast transportation revenue and ANR's first
    quarter 2015 settlement with a producer for damages to ANR's pipeline.
    These were partially offset by increased spending on pipeline integrity
    work 
--  higher earnings from U.S. Power mainly due to increased margins on and
    higher sales volumes to wholesale, commercial and industrial customers
    partially offset by lower earnings from U.S. generating assets primarily
    due to the impact of lower realized power prices 
--  lower earnings from Western Power as a result of lower realized power
    prices and lower PPA volumes 
--  higher interest expense from debt issuances and higher foreign exchange
    on interest related to U.S. dollar-denominated debt. 

The stronger U.S. dollar this quarter compared to the same period in 2014 positively impacted the translated results in our U.S. businesses, however, this impact was mostly offset by a corresponding increase in interest expense on U.S. dollar-denominated debt as well as realized losses on foreign exchange hedges used to manage our net exposure through our hedging program.


                                                                            
CAPITAL PROGRAM                                                             

We are developing quality projects under our long-term capital program. These long-life infrastructure assets are supported by long-term commercial arrangements with creditworthy counterparties or regulated business models and are expected to generate significant growth in earnings and cash flow.

Our capital program is comprised of $12 billion of small to medium-sized, shorter-term projects and $34 billion of commercially secured large-scale, medium and longer-term projects. Amounts presented exclude the impact of foreign exchange and capitalized interest.

Estimated project costs are generally based on the last announced project estimates and are subject to cost adjustments due to market conditions, route refinement, permitting conditions, scheduling and timing of regulatory permits.

CANADIAN PIPELINES

Net income and comparable EBITDA for our rate-regulated Canadian pipelines are generally affected by the approved ROE, investment base, level of deemed common equity, incentive earnings or losses and certain carrying charges. Changes in depreciation, financial charges and taxes also impact comparable EBITDA and comparable EBIT but do not impact net income as they are recovered in revenue on a flow-through basis.

----------------------------------------------------------------------------

Net income for the Canadian Mainline increased by $9 million for the three months ended June 30, 2015 compared to the same period in 2014 because of incentive earnings recorded in second quarter 2015 following approval by the NEB in June 2015 of the 2015 - 2020 Mainline Transportation Tolls Compliance Filing. This was partially offset by a lower ROE of 10.10 per cent on deemed common equity of 40 per cent in 2015 compared to 11.50 per cent in 2014 and a lower average investment base in 2015. Net income decreased by $10 million for the six months ended June 30, 2015 compared to the same period in 2014 due to a lower ROE and a lower average investment base in 2015, partially offset by the incentive earnings recorded in second quarter 2015.

Net income for the NGTL System increased by $8 million and $9 million for three and six months ended June 30, 2015 compared to the same periods in 2014 mainly due to a higher average investment base and no OM&A incentive losses realized in 2015.

U.S. AND INTERNATIONAL PIPELINES

Earnings for our U.S. natural gas pipelines operations are generally affected by contracted volume levels, volumes delivered and the rates charged as well as by the cost of providing services, including OM&A and property taxes. ANR is also affected by the contracting and pricing of its storage capacity and incidental commodity sales.

Comparable EBITDA for U.S. and International Pipelines was unchanged for the three months ended June 30, 2015 and increased by US$33 million for six months ended June 30, 2015 compared to the same periods in 2014. The year to date increase was the net effect of:


--  higher earnings from the Tamazunchale Extension which was placed in
    service in 2014 
--  higher ANR Southeast transportation revenue and ANR's first quarter 2015
    settlement with a producer for damages to ANR's pipeline, partially
    offset by increased spending on pipeline integrity work. 

A stronger U.S. dollar had a positive impact on the Canadian dollar equivalent comparable earnings from our U.S. and International operations.

COMPARABLE DEPRECIATION AND AMORTIZATION

Comparable depreciation and amortization increased by $19 million and $36 million for three and six months ended June 30, 2015 compared to the same periods in 2014 mainly because of depreciation for the Tamazunchale Extension, a higher investment base on the NGTL System and the effect of a stronger U.S. dollar.

BUSINESS DEVELOPMENT

Business development expenses were higher by $12 million and $21 million for the three and six months ended June 30, 2015 compared to the same periods in 2014 mainly due to increased business development activity.

Comparable EBITDA for the Keystone Pipeline System is generated primarily by providing pipeline capacity to shippers for fixed monthly payments that are not linked to actual throughput volumes. Uncontracted capacity is offered to the market on a spot basis and provides opportunities to generate incremental earnings.

Comparable EBITDA for the Keystone Pipeline System increased by $64 million and $130 million for the three and six months ended June 30, 2015 compared to the same periods in 2014. These increases were primarily due to:


--  higher uncontracted volumes 
--  incremental earnings from the Gulf Coast extension which was placed in
    service in late January 2014 
--  a stronger U.S. dollar and its positive effect on the foreign exchange
    impact 

COMPARABLE DEPRECIATION AND AMORTIZATION

Comparable depreciation and amortization increased by $12 million and $26 million for the three and six months ended June 30, 2015 compared to the same periods in 2014 due to the Gulf Coast extension being placed in service and the effect of a stronger U.S. dollar.

The period over period variances in these unrealized gains and losses reflect the impact of changes in forward natural gas and power prices and the volume of our positions for these particular derivatives over a certain period of time; however, they do not accurately reflect the gains and losses that will be realized on settlement, or the offsetting impact of other derivative and non-derivative transactions that make up our business as a whole. As a result, we do not consider them reflective of our underlying operations.

A significant portion of the unrealized risk management activity gains in U.S. Power for second quarter 2015 are due to the reversal of unrealized risk management activity losses from our power marketing business that were recognized and discussed in first quarter 2015. Please see the U.S. Power section of this MD&A for further discussion on these timing differences.

Canadian Power gains from risk management activities in second quarter 2015 are a result of higher Alberta forward power prices at June 30, 2015.

The remainder of the Energy segmented earnings are equivalent to comparable EBIT which, along with EBITDA, are discussed below.

Comparable EBITDA for Energy increased by $41 million for the three months ended June 30, 2015 compared to the same period in 2014 due to the net effect of:


--  higher earnings from Bruce Power from higher volumes as a result of
    fewer outage days at Bruce A, partially offset by lower Bruce B volumes
    due to increased planned outage days 
--  higher earnings from Eastern Power due to incremental earnings from
    Ontario solar facilities acquired in the second half of 2014 and higher
    earnings at Cartier Wind 
--  lower earnings from U.S. Power mainly due to the timing of earnings
    recognized on certain contracts in our power marketing business,
    reflecting the different pricing profiles between the power prices we
    charge our customers and the prices we pay for volumes purchased 
--  lower earnings from Western Power as a result of lower realized power
    prices and lower PPA volumes. 

Comparable EBITDA for Energy increased by $84 million for the six months ended June 30, 2015 compared to the same period in 2014 due to the net effect of:


--  higher earnings from Eastern Power due to the sale of unused natural gas
    transportation, higher contractual earnings at Becancour and incremental
    earnings from Ontario solar facilities acquired in 2014 
--  higher earnings from Bruce Power from increased volumes as a result of
    fewer outage days at Bruce A partially offset by lower Bruce B volumes
    due to increased planned outage days 
--  higher earnings from U.S. Power mainly due to increased margins and
    higher sales volumes to wholesale, commercial and industrial customers
    primarily offset by lower earnings on U.S. generating assets primarily
    due to the impact of lower realized power prices 
--  lower earnings from Western Power as a result of lower realized power
    prices and lower PPA volumes 
--  lower earnings from Natural Gas Storage due to lower realized natural
    gas price spreads 
--  a stronger U.S. dollar and its positive effect on the foreign exchange
    impact.

Western Power

Comparable EBITDA for Western Power decreased by $12 million and $69 million for the three and six months ended June 30, 2015 compared to the same periods in 2014. The decreases were primarily due to lower realized power prices, lower PPA volumes and lower earnings following the sale of Cancarb in April 2014.

Average spot market power prices in Alberta increased by 36 per cent from $42/MWh to $57/MWh for the three months ended June 30, 2015 and decreased 17 per cent from $52/MWh to $43/MWh for the six months ended June 30, 2015, compared to the same periods in 2014. Unexpected plant outages, lower wind output and higher weather driven power demand resulted in higher average spot power prices in second quarter 2015. Realized power prices on power sales can be higher or lower than spot market power prices in any given period as a result of contracting activities.

Although Alberta average spot power prices were higher in second quarter 2015, the market remains well supplied. Lower spot power prices are expected to continue in the near term and 2015 Western Power earnings are anticipated to be lower compared to 2014. Longer-term, we expect prices to return to higher levels as excess supply is absorbed by growth in power demand and aging generation infrastructure is retired.

Fifty-seven per cent of Western Power sales volumes were sold under contract in second quarter 2015 compared to 76 per cent in second quarter 2014.

Eastern Power

Comparable EBITDA for Eastern Power increased by $21 million for the three months ended June 30, 2015 compared to the same period in 2014 mainly due to incremental earnings from solar facilities acquired in 2014 and higher earnings at Cartier Wind.

Comparable EBITDA for Eastern Power increased by $59 million for the six months ended June 30, 2015 compared to the same period in 2014 mainly due to the sale of unused natural gas transportation, higher contractual earnings at Becancour and incremental earnings from solar facilities acquired in the second half of 2014.

Equity income from Bruce A increased by $93 million and $100 million for the three and six months ended June 30, 2015 compared to the same periods in 2014. These increases were mainly due to higher volumes resulting from fewer planned and unplanned outage days.

Equity income from Bruce B decreased by $51 million and $43 million for the three and six months ended June 30, 2015 compared to the same periods in 2014 mainly due to lower volumes resulting from higher planned outage days. All Bruce B units were removed from service in April 2015 to allow for inspection of the Bruce B vacuum building as mandated by the Canadian Nuclear Safety Commission to occur approximately once every decade. The outage, along with additional planned maintenance on Unit 6, was completed successfully during second quarter 2015.

Under a contract with the IESO, all of the output from Bruce A is sold at a fixed price/MWh which is adjusted annually on April 1 for inflation.

Amounts received under the Bruce B floor price mechanism within a calendar year are subject to repayment if the average spot price in a month exceeds the floor price. We expect 2015 spot power prices to be less than the floor price throughout 2015 and therefore no amounts received under the floor price mechanism in 2015 are expected to be repaid. Amounts received above the floor price in first quarter 2014 were repaid to the IESO in January 2015.

Bruce B also enters into fixed-price contracts under which it receives or pays the difference between the contract price and the spot price.

The contract also provides for payment if the IESO reduces Bruce Power's generation to balance the supply of and demand for electricity and/or manage other operating conditions of the Ontario power grid. The amount of the reduction is considered "deemed generation", for which Bruce Power is paid the fixed price, floor price or spot price as applicable under the contract.

Overall plant availability percentages in 2015 are expected to be in the mid 80s for Bruce A and Bruce B. In July 2015, additional planned outage work commenced on Bruce A Unit 4 and is expected to continue for approximately three months.

Comparable EBITDA for U.S. Power decreased US$24 million for the three months ended June 30, 2015 compared to the same period in 2014 primarily due to the net effect of:


--  the timing of recognizing earnings on certain contracts in our power
    marketing business due to different power pricing profiles between the
    prices we charge our customers and the prices we pay for volumes
    purchased 
--  lower realized capacity prices in New York 
--  higher margins and higher sales to wholesale, commercial and industrial
    customers. 

Comparable EBITDA for U.S. Power increased US$23 million for the six months ended June 30, 2015 compared to the same period in 2014 primarily due to the net effect of:


--  higher margins and higher sales volumes to wholesale, commercial and
    industrial customers 
--  lower realized capacity prices in New York 
--  lower realized power prices and generation at our facilities in New York
    and New England partially offset by lower fuel costs. 

The timing of recognizing earnings on certain contracts in our U.S. power marketing business is impacted by different power pricing profiles between the prices we charge our customers and the prices we pay for volumes purchased to fulfill our sales obligations over the term of the contracts. The costs on volumes purchased to fulfill power sales commitments to wholesale, commercial and industrial customers include the impact of certain contracts to purchase power over multiple periods at a flat price. Because the price we charge our customers is typically shaped to the market, the impact of these two contract pricing profiles has generally resulted in higher earnings in January to March, offset by lower earnings between April and December with overall positive margins realized over the term of the contracts. Due to increased natural gas and power prices experienced during winter 2014 and the impact on the pricing of our 2015 contracts in the New England market, these timing differences have been more significant in 2015. As discussed in our first quarter 2015 Report to Shareholders, the majority of the higher earnings in first quarter have been offset by lower earnings in second quarter.

Wholesale electricity prices in New York and New England were significantly lower for the three and six months ended June 30, 2015 compared to the same periods in 2014. In New England, spot power prices for the three and six months ended June 30, 2015 were 38 per cent and 41 per cent lower compared to the same periods in 2014. In New York City, spot power prices were 32 per cent and 42 per cent lower for the three and six months ended June 30, 2015 compared to the same periods in 2014. Spot capacity prices in New York City were, on average, 18 per cent and 16 per cent lower for the three and six months ended June 30, 2015 compared to the same periods in 2014. Reductions in fuel oil prices and increased availability of liquefied natural gas in winter 2015 helped to mitigate the impact of pipeline constraints and keep peak price excursions limited compared to winter 2014. Lower commodity prices and reduced price volatility contributed to higher margins on sales to wholesale, commercial and industrial customers by reducing the costs on volumes purchased to fulfill power sales commitments to these customers.

Physical sales volumes and purchased volumes sold to wholesale, commercial and industrial customers were higher than the same periods in 2014.

As at June 30, 2015, approximately 2,900 GWh or 58 per cent of U.S. Power's planned generation was contracted for the remainder of 2015 and 3,800 GWh or 40 per cent for 2016. Planned generation fluctuates depending on hydrology, wind conditions, commodity prices and the resulting dispatch of the assets. Power sales fluctuate based on customer usage.

NATURAL GAS STORAGE AND OTHER

Comparable EBITDA increased $4 million for the three months ended June 30, 2015 and decreased $20 million for six months ended June 30, 2015 compared to the same periods in 2014. The decrease in the six months ended June 30, 2015 was primarily due to decreased storage revenues as a result of lower realized natural gas price spreads. Extreme natural gas price volatility experienced in first quarter 2014 did not repeat in first quarter 2015.

NATURAL GAS PIPELINES

Canadian Regulated Pipelines

NGTL System

The NGTL System has approximately $6.8 billion of new supply and demand facilities under development. In second quarter 2015, we continued to advance several of these capital expansion projects and plan to file additional facilities applications for this program through the remainder of 2015. We have also received additional requests for firm receipt service that we anticipate will increase the overall capital spend on the NGTL System beyond the previously announced program and continue to work with our customers to best match their requirements for 2016, 2017 and 2018 in-service dates.

North Montney Mainline

On April 15, 2015, the NEB issued its report recommending the federal government approve the $1.7 billion North Montney Mainline project which will provide substantial new capacity on the NGTL System to meet the transportation requirements associated with rapidly increasing development of natural gas resources in the Montney supply basin in northeastern B.C. The project will connect Montney and other Western Canada Sedimentary Basin supply to both existing and new natural gas markets, including LNG markets.

The North Montney Mainline project will consist of two large diameter, 42-inch pipeline sections, Aitken Creek and Kahta, totaling approximately 301 km (187 miles) in length, and associated metering facilities, valve sites and compression facilities. The project will also include an interconnection with our proposed Prince Rupert Gas Transmission Project to provide natural gas supply to the proposed Pacific NorthWest (PNW) LNG liquefaction and export facility near Prince Rupert, B.C. We expect to have the Aitken Creek Section in service in late 2016 and the Kahta Section in service in 2017.

The NEB also approved the applied-for, rolled-in tolling design for the project costs during a transition period, subject to certain conditions which we are reviewing. Following the transition period, we will have the option of applying to the NEB for a revised tolling methodology, or the ability to implement stand-alone tolling on the project. We will engage shippers to determine an appropriate approach that best meets market requirements.

The Federal Government approved the recommendations of the report from the NEB and, on June 11, 2015, the NEB issued a Certificate of Public Convenience and Necessity to proceed with the project, subject to certain terms and conditions. Under one of these conditions, construction on the North Montney Mainline Project can only begin after a confirmation of FID has been made on the proposed PNW LNG project and we are proceeding with construction on PRGT.

Canadian Mainline

Canadian Mainline 2015-2020 Mainline Transportation Tolls Compliance Filing

On March 31, 2015, we submitted a compliance toll filing in response to direction from the NEB's RH-001-2014 Decision issued in November 2014. On June 12, 2015, the NEB approved the applied-for compliance tolls, as filed. These final tolls became effective on July 1, 2015 which allowed, among other things, the recording of incentive earnings as approved by the NEB.

Kings North Connection Project

On June 2, 2015, the NEB approved construction of the King's North Connection project to expand gas transmission capacity in the greater Toronto area and provide shippers with the flexibility to source growing supplies of Marcellus gas from the U.S. Northeast. The project is expected to cost approximately $220 million and is anticipated to be in-service by third quarter 2016.

U.S. Pipelines

Sale of GTN Pipeline to TC PipeLines, LP

On April 1, 2015, we closed the sale of our remaining 30 per cent interest in Gas Transmission Northwest LLC (GTN) to our master limited partnership, TC PipeLines, LP for an aggregate purchase price of US$446 million plus a purchase price adjustment of US$11 million. The US$457 million sale was comprised of US$264 million in cash, the assumption of US$98 million in proportional GTN debt and US$95 million of new Class B units of TC PipeLines, LP. The Class B units entitle us to a cash distribution based on 30 per cent of GTN's annual cash distribution after certain thresholds are achieved, namely 100 per cent of distributions above US$20 million in the first five years and 25 per cent of distributions above US$20 million in subsequent years.

LNG Pipeline Projects

Prince Rupert Gas Transmission

In second quarter 2015, we received six of 11 pipeline and facilities permits to build and operate the Prince Rupert Gas Transmission pipeline project from the B.C. Oil and Gas Commission (BC OGC). We anticipate decisions on the remaining BC OGC permits in third quarter 2015.

We continued our engagement with Aboriginal groups along the pipeline route and during the quarter announced the signing of project agreements with Gitanyow First Nation, Kitselas First Nation, Lake Babine Nation, Doig River First Nation, Halfway River First Nation and Yekooche First Nation.

On June 11, 2015, PNW LNG announced a positive FID for the proposed liquefaction and export facility, subject to two conditions. The first condition is approval by the Legislative Assembly of B.C. of a Project Development Agreement between PNW LNG and the Province of B.C. This condition was satisfied in mid-July 2015. The second condition is a positive regulatory decision on PNW LNG's environmental assessment by the Government of Canada.

Subject to successful completion of the regulatory process for PRGT, we remain on target to begin construction following confirmation of a FID by PNW LNG. The in-service date for PRGT is estimated to be 2020 but will be aligned with PNW LNG's liquefaction facility timeline.

Coastal GasLink

We have received eight of ten pipeline and facilities permits from the BC OGC and anticipate receiving the remaining two permits in third quarter 2015. We are continuing our engagement with Aboriginal groups along the pipeline route and, on June 29, 2015, we announced the signing of project agreements with Wet'suwet'en First Nation, Skin Tyee Nation, Nee-Tahi-Buhn Band, Yekooche First Nation, Doig River First Nation and Halfway River First Nation, all of northern B.C.

LIQUIDS PIPELINES

Houston Lateral and Terminal

Construction continues on the 77 km (48 mile) Houston Lateral pipeline and tank terminal which will extend the Keystone Pipeline System to Houston, Texas refineries. The terminal is expected to have initial storage capacity for 700,000 barrels of crude oil. The pipeline and terminal are expected to be completed in fourth quarter 2015.

On April 14, 2015, we, along with Magellan Midstream Partners L.P. (Magellan), announced a joint development agreement to connect our Houston Terminal to Magellan's East Houston Terminal. We will own 50 per cent of this US$50 million pipeline project which will enhance connections to the Houston market for our Keystone Pipeline System. Subject to definitive agreements and receipt of necessary permits and approvals, the pipeline is expected to be operational in late 2016.

Keystone XL

In January 2015, the DOS re-initiated the national interest review and requested the eight federal agencies with a role in the review to complete their consideration of whether Keystone XL serves the national interest. All of the agency comments were submitted.

On February 2, 2015, the U.S. Environmental Protection Agency (EPA) posted a comment letter to its website suggesting that, among other things, the FSEIS issued by the DOS had not fully and completely assessed the environmental impacts of Keystone XL and that, at lower crude oil prices, Keystone XL may increase the rates of oil sands production and greenhouse gas emissions. On February 10, 2015, we sent a letter to the DOS refuting these and other comments in the EPA letter and offered to work with the DOS to ensure it has all the relevant information to allow it to reach a decision to approve Keystone XL.

On February 12, 2015, Nebraska county courts granted temporary injunctions that were negotiated between us and landowners' counsel which prevent Keystone from proceeding with condemnation cases until the underlying constitutional litigation is resolved. A renewed challenge to the constitutionality of the statute under which the Governor approved the re-route in the state is pending in a Nebraska District Court.

On February 24, 2015, U.S. President Obama vetoed Congressional legislation that would have granted us authority to construct Keystone XL across the international border. The U.S. President stated that the legislation circumvented a final DOS assessment. The timing and ultimate resolution of Keystone XL's pending application for a Presidential Permit remains uncertain.

On June 29, 2015, we sent a letter to the DOS with additional evidence demonstrating that Canada is taking strong steps toward managing carbon emissions.

The South Dakota Public Utility Commission has scheduled a hearing in third quarter 2015 on our request to certify our existing permit authority in that state.

The estimated capital cost for Keystone XL is expected to be approximately US$8.0 billion. As of June 30, 2015, we have invested US$2.4 billion in the project and have also capitalized interest in the amount of US$0.4 billion.

Energy East Pipeline

On April 2, 2015, we announced that the marine and associated tank terminal in Cacouna, Quebec will not be built as a result of the recommended reclassification of beluga whales as an endangered species. We are currently evaluating other options and amendments to the project are expected to be submitted to the NEB in fourth quarter 2015. The NEB has continued to process the application in the interim.

The alteration to the project scope and further refinement of the project schedule is expected to result in an in-service date of 2020. The original $12 billion cost estimate is expected to increase due to further scope refinement as we consult with stakeholders and escalation of construction costs as the project schedule is refined.

Binding long-term contracts of approximately one million Bbl/d for the 1.1 million Bbl/d pipeline have been secured and discussions with shippers continue.

Heartland Pipeline and TC Terminals

On May 7, 2015, the Alberta Energy Regulator issued a permit for construction of the Heartland Pipeline. The in-service date of the project will be aligned to meet market requirements for incremental capacity between the Heartland region near Edmonton, Alberta and Hardisty, Alberta.

On May 7, 2015, the Alberta Energy Regulator issued a permit for construction of the Heartland Pipeline. The in-service date of the project will be aligned to meet market requirements for incremental capacity between the Heartland region near Edmonton, Alberta and Hardisty, Alberta.

Crude oil prices continue to remain low, prompting many producers to cut capital spending and delay oil sands projects in western Canada. In its 2015 Crude Oil Forecast, Markets and Transportation report, the Canadian Association of Petroleum Producers estimated WCSB crude oil production will continue to grow but at a slower pace than previously anticipated. Our liquids pipelines projects are supported by long-term contracts. However, with the slowing in growth of crude oil production, our intra-Alberta projects may experience a similar slowing pace of growth to align with the market.

Upland Pipeline

On April 22, 2015, we filed an application to obtain a U.S. Presidential Permit for the Upland Pipeline. The US$600 million Upland Pipeline is a 400 km (240 mile) crude oil pipeline which will provide transportation from, and between, multiple points in North Dakota and interconnect with the Energy East Pipeline at Moosomin, Saskatchewan. Subject to regulatory approvals, we anticipate the Upland Pipeline to be in service in 2020. The commercial contracts we have executed for Upland Pipeline are conditioned on the Energy East pipeline project proceeding.

ENERGY

Alberta Greenhouse Gas Emissions

On June 25, 2015, the Alberta government announced a renewal and change to the Specified Gas Emitters Regulations (SGER) in Alberta. Since 2007 under the SGER, established industrial facilities with GHG emissions above a certain threshold are required to reduce their emissions by 12 per cent below an average intensity baseline and a carbon levy of $15 per tonne is placed on emissions above this target. The changed regulations include an increase in the emissions reductions target to 15 per cent in 2016 and 20 per cent in 2017, along with an increase in the carbon levy to $20 per tonne in 2016 and $30 per tonne in 2017. Our Sundance and Sheerness PPA's are subject to this regulation. Our significant inventory of carbon offset credits are expected to mitigate the majority of these increased costs. The remaining compliance costs are expected to be recovered through increased market pricing and contract flow through provisions.

Ravenswood

In late May 2015, the 972 MW Unit 30 at the Ravenswood Generating Station returned to service after a September 2014 unplanned outage which resulted from a problem with the generator associated with the high pressure turbine.

Comparable interest expense increased by $34 million and $78 million for the three and six months ended June 30, 2015 compared to the same periods in 2014 due to the net effect of:


--  higher interest expense due to debt issues of: 
    --  US$750 million in May 2015 
    --  US$750 million in March 2015 
    --  US$350 million in March 2015 by TC PipeLines, LP 
    --  US$750 million in January 2015 
    --  US$1.25 billion in February 2014 
    --  partially offset by Canadian and U.S. dollar-denominated debt
        maturities 
--  a stronger U.S. dollar and its effect on the foreign exchange impact on
    interest expense related to U.S. dollar-denominated debt.

Comparable interest income and other expense increased by $22 million and $43 million for the three and six months ended June 30, 2015 compared to the same periods in 2014. This is the net result of:


--  increased AFUDC related to our rate-regulated projects, primarily the
    Energy East Pipeline and our Mexico pipelines 
--  higher realized losses in 2015 compared to 2014 on derivatives used to
    manage our net exposure to foreign exchange rate fluctuations on U.S.
    dollar denominated income 
--  the impact of a strengthening U.S. dollar on the translation of foreign
    currency denominated working capital.

Comparable income tax expense increased by $23 million and $46 million for the three and six months ended June 30, 2015 compared to the same periods in 2014. The increase was mainly the result of higher pre-tax earnings in 2015 compared to 2014 and changes in the proportion of income earned between Canadian and foreign jurisdictions, partially offset by lower flow-through taxes in 2015 on Canadian regulated pipelines.

Net income attributable to non-controlling interests increased by $9 million and $14 million for the three and six months ended June 30, 2015 compared to the same periods in 2014 primarily due to the sale of our remaining 30 per cent direct interests in GTN in April 2015 and Bison in October 2014 to TC PipeLines, LP and the impact of a stronger U.S. dollar on the Canadian dollar equivalent earnings from TC PipeLines, LP.


                                                                            
                                                                            
                                                                            
Financial condition                                                         

We strive to maintain strong financial capacity and flexibility in all parts of the economic cycle. We rely on our operating cash flow to sustain our business, pay dividends and fund a portion of our growth. In addition, we access capital markets to meet our financing needs, manage our capital structure and to preserve our credit ratings.

We believe we have the financial capacity to fund our existing capital program through our predictable cash flow from our operations, access to capital markets, proceeds from the sale of U.S. natural gas pipeline assets to TC PipeLines, LP, cash on hand and substantial committed credit facilities.

At June 30, 2015, our current assets were $3.7 billion and current liabilities were $7.2 billion, leaving us with a working capital deficit of $3.5 billion compared to $4.0 billion at December 31, 2014. This working capital deficiency is considered to be in the normal course of business and is managed through:


--  our ability to generate cash flow from operations 
--  our access to capital markets 
--  approximately $6.0 billion of unutilized, unsecured credit facilities.

Capital expenditures in 2015 were primarily related to:


--  the expansion of the NGTL System 
--  construction of Mexico pipelines 
--  construction of the Northern Courier pipeline 
--  continued work on the ANR pipeline expansion 
--  construction of the Napanee power project. 

Costs incurred on capital projects under development primarily relate to the Energy East Pipeline and LNG pipeline projects.

Equity investments have increased in 2015 compared to 2014 primarily due to our investment in Grand Rapids.

    interest to the date of redemption.                                     
(2) The Junior subordinated notes were issued to TransCanada Trust. The     
    interest rate is fixed at 5.875 per cent per annum and will reset       
    starting May 2025 until May 2045 to the three month LIBOR plus 3.778 per

    to the three month LIBOR plus 4.528 per cent per annum.                 

TransCanada Trust (the Trust), our 100 per cent owned financing trust subsidiary of TCPL, issued US$750 million Trust Notes - Series 2015-A (Trust Notes) to third party investors with a fixed interest rate of 5.625 per cent for the first ten years converting to a floating rate thereafter. All of the proceeds of the issuance by the Trust were loaned to us in US$750 million junior subordinated notes of TCPL at a rate of 5.875 per cent which includes a 0.25 per cent administration charge. While the obligations of the Trust are fully and unconditionally guaranteed by TCPL, on a subordinated basis, the Trust is not consolidated in our financial statements as TCPL does not have a variable interest in the Trust and the only substantive assets of the Trust are receivables from TCPL.

PREFERRED SHARE ISSUANCE AND CONVERSION

In June 2015, holders of 5.5 million Series 3 cumulative redeemable first preferred shares exercised their option to convert to Series 4 cumulative redeemable first preferred shares and receive quarterly floating rate cumulative, dividends at an annual rate equal to the applicable 90-day Government of Canada treasury bill rate plus 1.28 per cent which will reset every quarter going forward. The fixed dividend rate on the remaining Series 3 preferred shares was reset for five years at 2.152 per cent per annum.

In March 2015, we completed a public offering of 10 million Series 11 cumulative redeemable first preferred shares at $25 per share resulting in gross proceeds of $250 million. The Series 11 preferred shareholders will have the right to convert their Series 11 preferred shares into Series 12 cumulative redeemable first preferred shares on November 30, 2020 and on November 30 of every fifth year thereafter. The holders of Series 12 preferred shares will be entitled to receive quarterly floating rate cumulative dividends at an annual rate equal to the applicable 90-day Government of Canada treasury bill rate plus 2.96 per cent.

The following table summarizes the impact of the above transactions on the Series 3, 4 and 11 preferred shares at June 30, 2015:

    dividends as and when declared by the Board.                            
(2) We may, at our option, redeem all or a portion of the outstanding       
    preferred shares for the redemption price per share, plus all accrued   
    and unpaid dividends on the redemption option date and on every fifth   
    anniversary date thereafter.                                            
(3) Commencing June 30, 2015, the floating quarterly dividend rate for the  
    Series 4 preferred shares is 1.945 per cent and will reset every quarter
    going forward.                                                          

The net proceeds of the above debt and Series 11 preferred share offerings were used for general corporate purposes and to reduce short-term indebtedness.

CREDIT FACILITIES

We use committed revolving credit facilities to support our commercial paper programs and, along with demand facilities, for general corporate purposes including issuing letters of credit as well as providing additional liquidity.

At June 30, 2015, we had approximately $7 billion in unsecured credit facilities, including:

At June 30, 2015, our operated affiliates had $0.6 billion of undrawn capacity on committed credit facilities.

See Financial risks and financial instruments for more information about liquidity, market and other risks.

CONTRACTUAL OBLIGATIONS

Our capital commitments have decreased by approximately $0.2 billion since December 31, 2014 as a result of the completion or advancement of capital projects partially offset by new commitments for the Napanee generating facility. Our other purchase obligations have increased by approximately $0.1 billion since December 31, 2014 primarily due to an increase in commodity purchase obligations and information technology and communication contracts. There were no other material changes to our contractual obligations in second quarter 2015 or to payments due in the next five years or after. See the MD&A in our 2014 Annual Report for more information about our contractual obligations.


                                                                            
Financial risks and financial instruments                                   

We are exposed to liquidity risk, counterparty credit risk and market risk, and have strategies, policies and limits in place to mitigate their impact on our earnings, cash flow and, ultimately, shareholder value. These are designed to ensure our risks and related exposures are in line with our business objectives and risk tolerance.

See our 2014 Annual Report for more information about the risks we face in our business. Our risks have not changed substantially since December 31, 2014.

LIQUIDITY RISK

We manage our liquidity risk by continuously forecasting our cash requirements for a rolling twelve month period and making sure we have adequate cash balances, cash flow from operations, committed and demand credit facilities and access to capital markets to meet our operating, financing and capital expenditure obligations under both normal and stressed economic conditions.

COUNTERPARTY CREDIT RISK

We have exposure to counterparty credit risk in the following areas:


--  accounts receivable 
--  portfolio investments 
--  the fair value of derivative assets 
--  cash and notes receivable. 

We review our accounts receivable regularly and record allowances for doubtful accounts using the specific identification method. At June 30, 2015, we had not incurred any significant credit losses and had no significant amounts past due or impaired. We had a credit risk concentration due from a counterparty of $222 million (US$178 million) and $258 million (US$222 million) at June 30, 2015 and December 31, 2014, respectively. This amount is expected to be fully collectible and is secured by a guarantee from the counterparty's investment grade parent company.

We have significant credit and performance exposure to financial institutions because they hold cash deposits and provide committed credit lines and letters of credit that help manage our exposure to counterparties and provide liquidity in commodity, foreign exchange and interest rate derivative markets.

FOREIGN EXCHANGE AND INTEREST RATE RISK

Certain of our businesses generate income in U.S. dollars, but since we report in Canadian dollars, changes in the value of the U.S. dollar against the Canadian dollar can affect our net income. As our U.S. dollar-denominated operations continue to grow, this exposure increases. The majority of this risk is offset by interest expense on U.S. dollar-denominated debt and by using foreign exchange derivatives.

We have floating interest rate debt and floating rate preferred shares (Series 2 and Series 4) which subject us to interest rate cash flow risk. We use interest rate swaps to help manage this risk.

FINANCIAL INSTRUMENTS

All financial instruments, including both derivative and non-derivative instruments, are recorded on the balance sheet at fair value unless they were entered into and continue to be held for the purpose of receipt or delivery in accordance with our normal purchase and sales exemptions and are documented as such. In addition, fair value accounting is not required for other financial instruments that qualify for certain accounting exemptions.

Non-derivative financial instruments

Fair value of non-derivative financial instruments

The fair value of our notes receivable is calculated by discounting future payments of interest and principal using forward interest rates. The fair value of long-term debt and junior subordinated notes has been estimated using an income approach based on quoted market prices for the same or similar debt instruments from external data providers.

Available for sale assets are recorded at fair value which is calculated using quoted market prices where available. Certain non-derivative financial instruments including cash and cash equivalents, accounts receivable, intangible and other assets, notes payable, accounts payable and other, accrued interest and other long-term liabilities have carrying amounts that approximate their fair value due to the nature of the item or the short time to maturity and would also be classified in Level II of the fair value hierarchy.

Credit risk has been taken into consideration when calculating the fair value of non-derivative financial instruments.

Derivative instruments

We use derivative instruments to reduce volatility associated with fluctuations in commodity prices, interest rates and foreign exchange rates. We apply hedge accounting to derivative instruments that qualify and are designated for hedge accounting treatment. The effective portion of the change in the fair value of hedging derivatives for cash flow hedges and hedges of our net investment in foreign operations are recorded in OCI in the period of change. Any ineffective portion is recognized in net income in the same financial category as the underlying transaction. The change in the fair value of derivative instruments that have been designated as fair value hedges are recorded in net income in interest income and other expense and interest expense.

The majority of derivative instruments that are not designated or do not qualify for hedge accounting treatment have been entered into as economic hedges to manage our exposure to market risk (held for trading). Changes in the fair value of held for trading derivative instruments are recorded in net income in the period of change. This may expose us to increased variability in reported operating results since the fair value of the held for trading derivative instruments can fluctuate significantly from period to period.

The recognition of gains and losses on derivatives for Canadian natural gas regulated pipelines exposures is determined through the regulatory process. Gains and losses arising from changes in the fair value of derivatives accounted for as part of RRA, including those that qualify for hedge accounting treatment, can be recovered or refunded through the tolls charged by us. As a result, these gains and losses are deferred as regulatory assets or regulatory liabilities and are refunded to or collected from the ratepayers in subsequent years when the derivative settles.

The fair value of foreign exchange and interest rate derivatives has been calculated using the income approach which uses period-end market rates and applies a discounted cash flow valuation model. The fair value of power and natural gas derivatives has been calculated using quoted market prices where available. In the absence of quoted market prices, third-party broker quotes or other valuation techniques have been used. Credit risk has been taken into consideration when calculating the fair value of derivative instruments.

Balance sheet presentation of derivative instruments

The balance sheet classification of the fair value of the derivative instruments is as follows:

    For the three and six months ended June 30, 2015 and 2014, there were no
    gains or losses included in net income relating to discontinued cash    
    flow hedges where it was probable that the anticipated transaction would
    not occur.

Credit risk related contingent features of derivative instruments

Derivatives contracts often contain financial assurance provisions that may require us to provide collateral if a credit risk related contingent event occurs (for example, if our credit rating is downgraded to non-investment grade).

Based on contracts in place and market prices at June 30, 2015, the aggregate fair value of all derivative contracts with credit-risk-related contingent features that were in a net liability position was $4 million (December 31, 2014 - $15 million), with collateral provided in the normal course of business of nil (December 31, 2014 - nil). If the credit-risk-related contingent features in these agreements had been triggered on June 30, 2015, we would have been required to provide collateral of $4 million (December 31, 2014 - $15 million) to our counterparties. Collateral may also need to be provided should the fair value of derivative instruments exceed pre-defined contractual exposure limit thresholds.

We have sufficient liquidity in the form of cash and undrawn committed revolving bank lines to meet these contingent obligations should they arise.

CONTROLS AND PROCEDURES

Management, including our President and CEO and our CFO, evaluated the effectiveness of our disclosure controls and procedures as at June 30, 2015, as required by the Canadian securities regulatory authorities and by the SEC, and concluded that our disclosure controls and procedures are effective at a reasonable assurance level.

There were no changes in second quarter 2015 that had or are likely to have a material impact on our internal control over financial reporting.

CRITICAL ACCOUNTING ESTIMATES AND ACCOUNTING POLICY CHANGES

When we prepare financial statements that conform with U.S. GAAP, we are required to make estimates and assumptions that affect the timing and amount we record for our assets, liabilities, revenues and expenses because these items may be affected by future events. We base the estimates and assumptions on the most current information available, using our best judgement. We also regularly assess the assets and liabilities themselves. You can find a summary of our critical accounting estimates in our 2014 Annual Report.

Our significant accounting policies have remained unchanged since December 31, 2014 other than described below. You can find a summary of our significant accounting policies in our 2014 Annual Report.

Changes in accounting policies for 2015

Reporting discontinued operations

In April 2014, the FASB issued amended guidance on the reporting of discontinued operations. The criteria of what will qualify as a discontinued operation has changed and there are expanded disclosures required. This new guidance was applied prospectively from January 1, 2015 and there was no impact on our consolidated financial statements as a result of applying this new standard.

Future accounting changes

Revenue from contracts with customers

In 2014, the FASB issued new guidance on revenue from contracts with customers. This guidance supersedes the current revenue recognition requirements and most industry-specific guidance. This new guidance requires that an entity recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In July 2015, the FASB agreed to defer the effective date of this new standard to January 1, 2018, with early adoption not permitted before January 1, 2017. There are two methods in which the amendment can be applied: (1) retrospectively to each prior reporting period presented, or (2) retrospectively with the cumulative effect recognized at the date of initial application.

We are currently evaluating the impact of the adoption of this ASU and have not yet determined the effect on our consolidated financial statements.

Extraordinary and unusual income statement items

In January 2015, the FASB issued new guidance on extraordinary and unusual income statement items. This update eliminates from GAAP the concept of extraordinary items. This new guidance is effective from January 1, 2016 and will be applied prospectively. We do not expect the adoption of this new standard to have a material impact on our consolidated financial statements.

Consolidation

In February 2015, the FASB issued new guidance on consolidation analysis. This update requires that entities reevaluate whether they should consolidate certain legal entities and eliminates the presumption that a general partner should consolidate a limited partnership. This new guidance is effective from January 1, 2016 and will be applied retrospectively. We are currently evaluating the impact of the adoption of this ASU and have not yet determined the effect on our consolidated financial statements.

Imputation of interest

In April 2015, the FASB issued new guidance on simplifying the accounting for debt issuance costs. The amendments in this update require that debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of the debt liability consistent with debt discounts or premiums. This new guidance is effective January 1, 2016 and will be applied retrospectively. The application of this amendment will result in a reclassification of debt issuance costs currently recorded in intangible and other assets to an offset of their respective debt liabilities.

FACTORS AFFECTING QUARTERLY FINANCIAL INFORMATION BY BUSINESS SEGMENT

Quarter-over-quarter revenues and net income sometimes fluctuate, the causes of which vary across our business segments.

In Natural Gas Pipelines, quarter-over-quarter revenues and net income from the Canadian regulated pipelines generally remain relatively stable during any fiscal year. Our U.S. natural gas pipelines are generally seasonal in nature with higher earnings in the winter months as a result of increased customer demands. Over the long term, however, results from both our Canadian and U.S. natural gas pipelines fluctuate because of:


--  regulatory decisions 
--  negotiated settlements with shippers 
--  acquisitions and divestitures 
--  developments outside of the normal course of operations 
--  newly constructed assets being placed in service. 

In Liquids Pipelines, annual revenues and net income are based on contracted crude oil transportation and uncommitted spot transportation. Quarter-over-quarter revenues and net income are affected by:


--  developments outside of the normal course of operations 
--  newly constructed assets being placed in service 
--  regulatory decisions. 

In Energy, quarter-over-quarter revenues and net income are affected by:


--  weather 
--  customer demand 
--  market prices for natural gas and power 
--  capacity prices and payments 
--  planned and unplanned plant outages 
--  acquisitions and divestitures 
--  certain fair value adjustments 
--  developments outside of the normal course of operations 
--  newly constructed assets being placed in service. 

FACTORS AFFECTING FINANCIAL INFORMATION BY QUARTER

We calculate comparable measures by adjusting certain GAAP and non-GAAP measures for specific items we believe are significant but not reflective of our underlying operations in the period.

Comparable earnings exclude the unrealized gains and losses from changes in the fair value of certain derivatives used to reduce our exposure to certain financial and commodity price risks. These derivatives generally provide effective economic hedges, but do not meet the criteria for hedge accounting. As a result, the changes in fair value are recorded in net income. As these amounts do not accurately reflect the gains and losses that will be realized at settlement, we do not consider them part of our underlying operations.

In second quarter 2015, comparable earnings excluded a $34 million adjustment to income tax expense due to the enactment of an increase in the Alberta corporate income tax rate in June 2015 and a charge of $8 million after-tax for severance costs primarily as a result of the restructuring of our major projects group in response to delayed timelines on certain of our major projects along with a continued focus on enhancing the efficiency and effectiveness of our operations.

In fourth quarter 2014, comparable earnings excluded an $8 million after-tax gain on the sale of Gas Pacifico/INNERGY.

In second quarter 2014, comparable earnings excluded a $99 million after-tax gain on the sale of Cancarb Limited and a $31 million after-tax loss related to the termination of the Niska Gas Storage contract.

1. Basis of presentation                                                    

These condensed consolidated financial statements of TransCanada Corporation (TransCanada or the Company) have been prepared by management in accordance with U.S. GAAP. The accounting policies applied are consistent with those outlined in TransCanada's annual audited consolidated financial statements for the year ended December 31, 2014. Capitalized and abbreviated terms that are used but not otherwise defined herein are identified in TransCanada's 2014 Annual Report.

These condensed consolidated financial statements reflect adjustments, all of which are normal recurring adjustments that are, in the opinion of management, necessary to reflect fairly the financial position and results of operations for the respective periods. These condensed consolidated financial statements do not include all disclosures required in the annual financial statements and should be read in conjunction with the 2014 audited consolidated financial statements included in TransCanada's 2014 Annual Report. Certain comparative figures have been reclassified to conform with the current period's presentation.

Earnings for interim periods may not be indicative of results for the fiscal year in the Company's Natural Gas Pipelines segment due to the timing of regulatory decisions and seasonal fluctuations in short-term throughput volumes on U.S. pipelines. Earnings for interim periods may also not be indicative of results for the fiscal year in the Company's Energy segment due to the impact of seasonal weather conditions on customer demand and market pricing in certain of the Company's investments in electrical power generation plants and non-regulated gas storage facilities.

USE OF ESTIMATES AND JUDGEMENTS

In preparing these financial statements, TransCanada is required to make estimates and assumptions that affect both the amount and timing of recording assets, liabilities, revenues and expenses since the determination of these items may be dependent on future events. The Company uses the most current information available and exercises careful judgement in making these estimates and assumptions. In the opinion of management, these condensed consolidated financial statements have been properly prepared within reasonable limits of materiality and within the framework of the Company's significant accounting policies included in the consolidated financial statements for the year ended December 31, 2014, except as described in Note 2, Changes in accounting policies.


                                                                            
                                                                            
                                                                            
2. Changes in accounting policies                                           

CHANGES IN ACCOUNTING POLICIES FOR 2015

Reporting discontinued operations

In April 2014, the FASB issued amended guidance on the reporting of discontinued operations. The criteria of what will qualify as a discontinued operation has changed and there are expanded disclosures required. This new guidance was applied prospectively from January 1, 2015 and there was no impact on the Company's consolidated financial statements as a result of applying this new standard.

FUTURE ACCOUNTING CHANGES

Revenue from contracts with customers

In May 2014, the FASB issued new guidance on revenue from contracts with customers. This guidance supersedes the current revenue recognition requirements and most industry-specific guidance. This new guidance requires that an entity recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In July 2015, the FASB agreed to defer the effective date of this new standard to January 1, 2018, with early adoption not permitted before January 1, 2017. There are two methods in which the amendment can be applied: (1) retrospectively to each prior reporting period presented, or (2) retrospectively with the cumulative effect recognized at the date of initial application.

The Company is currently evaluating the impact of the adoption of this ASU and has not yet determined the effect on its consolidated financial statements.

Extraordinary and unusual income statement items

In January 2015, the FASB issued new guidance on extraordinary and unusual income statement items. This update eliminates from GAAP the concept of extraordinary items. This new guidance is effective from January 1, 2016 and will be applied prospectively. The Company does not expect the adoption of this new standard to have a material impact on its consolidated financial statements.

Consolidation

In February 2015, the FASB issued new guidance on consolidation analysis. This update requires that entities reevaluate whether they should consolidate certain legal entities and eliminates the presumption that a general partner should consolidate a limited partnership. This new guidance is effective from January 1, 2016 and will be applied retrospectively. The Company is currently evaluating the impact of the adoption of this ASU and has not yet determined the effect on its consolidated financial statements.

Imputation of interest

In April 2015, the FASB issued new guidance on simplifying the accounting for debt issuance costs. The amendments in this update require that debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of the debt liability consistent with debt discounts or premiums. This new guidance is effective January 1, 2016 and will be applied retrospectively. The application of this amendment will result in a reclassification of debt issuance costs currently recorded in intangible and other assets to an offset of their respective debt liabilities.

4. Pipeline abandonment costs                                               

As a result of the NEB's Land Matters Consultation Initiative (LMCI), TransCanada is required to collect funds to cover estimated future pipeline abandonment costs for all NEB regulated Canadian pipelines. Amounts collected are included in regulatory liabilities on the condensed consolidated balance sheet. As at June 30, 2015, regulatory liabilities included $117 million (December 31, 2014 - nil) of estimated future abandonment costs on the condensed consolidated balance sheet.

Collected funds are placed in trusts that hold and invest the funds and are accounted for as restricted investments. As at June 30, 2015, intangible and other assets included $117 million (December 31, 2014 - nil) of LMCI restricted investments on the condensed consolidated balance sheet. Please refer to Note 11 for information on the fair values of these investments which are classified as available for sale.


                                                                            
                                                                            
                                                                            
5. Income taxes                                                             

At June 30, 2015, the total unrecognized tax benefit of uncertain tax positions was approximately $19 million (December 31, 2014 - $18 million). TransCanada recognizes interest and penalties related to income tax uncertainties in income tax expense. Included in income tax expense for the three and six months ended June 30, 2015 is nil for interest expense and nil for penalties (June 30, 2014 - $1 million and nil, respectively, of income for the reversal of interest expense and nil for penalties). At June 30, 2015, the Company had $5 million accrued for interest expense and nil accrued for penalties (December 31, 2014 - $5 million accrued for interest expense and nil for penalties).

The effective tax rates for the six-month periods ended June 30, 2015 and 2014 were 32 per cent and 29 per cent, respectively. The higher effective tax rate in 2015 was primarily the result of an increase in the Alberta statutory tax rate and changes in the proportion of income earned between Canadian and foreign jurisdictions.

While the obligations of the Trust are fully and unconditionally guaranteed by TCPL, on a subordinated basis, the Trust is not consolidated in TransCanada's financial statements because TCPL does not have a variable interest in the Trust and the only substantive assets of the Trust are receivables from TCPL.

In June 2015, holders of 5.5 million Series 3 cumulative redeemable first preferred shares exercised their option to convert to Series 4 cumulative redeemable first preferred shares and receive quarterly floating rate cumulative dividends at an annual rate equal to the applicable 90-day Government of Canada treasury bill rate plus 1.28 per cent which will reset every quarter going forward. The fixed dividend rate on the remaining Series 3 preferred shares was reset for five years at 2.152 per cent per annum.

In March 2015, TransCanada completed a public offering of 10 million Series 11 cumulative redeemable first preferred shares at $25 per share resulting in gross proceeds of $250 million. The Series 11 preferred shareholders will have the right to convert their Series 11 preferred shares into Series 12 cumulative redeemable first preferred shares on November 30, 2020 and on November 30 of every fifth year thereafter. The holders of Series 12 preferred shares will be entitled to receive quarterly floating rate cumulative dividends at an annual rate equal to the applicable 90-day Government of Canada treasury bill rate plus 2.96 per cent.

11. Risk management and financial instruments                               

RISK MANAGEMENT OVERVIEW

TransCanada has exposure to market risk and counterparty credit risk, and has strategies, policies and limits in place to manage the impact of these risks on earnings, cash flow and, ultimately, shareholder value.

COUNTERPARTY CREDIT RISK

TransCanada's maximum counterparty credit exposure with respect to financial instruments at June 30, 2015, without taking into account security held, consisted of accounts receivable, portfolio investments recorded at fair value, the fair value of derivative assets and notes, loans and advances receivable. At June 30, 2015, there were no significant amounts past due or impaired, and there were no significant credit losses during the period.

The Company had a credit risk concentration due from a counterparty of $222 million (US$178 million) and $258 million (US$222 million) at June 30, 2015 and December 31, 2014, respectively.

FINANCIAL INSTRUMENTS

Non-derivative financial instruments

Fair value of non-derivative financial instruments

The fair value of the Company's notes receivable is calculated by discounting future payments of interest and principal using forward interest rates. The fair value of long-term debt and junior subordinated notes is estimated using an income approach based on quoted market prices for the same or similar debt instruments from external data service providers.

Available for sale assets are recorded at fair value which is calculated using quoted market prices where available. Certain non-derivative financial instruments included in cash and cash equivalents, accounts receivable, intangible and other assets, notes payable, accounts payable and other, accrued interest and other long-term liabilities have carrying amounts that approximate their fair value due to the nature of the item or the short time to maturity and would also be classified in Level II of the fair value hierarchy.

Credit risk has been taken into consideration when calculating the fair value of non-derivative instruments.

Derivative instruments

Fair value of derivative instruments

The fair value of foreign exchange and interest rate derivatives has been calculated using the income approach which uses period end market rates and applies a discounted cash flow valuation model. The fair value of power and natural gas derivatives has been calculated using quoted market prices where available. In the absence of quoted market prices, third-party broker quotes or other valuation techniques have been used. Credit risk has been taken into consideration when calculating the fair value of derivative instruments.

In some cases, even though the derivatives are considered to be effective economic hedges, they do not meet the specific criteria for hedge accounting treatment or are not designated as a hedge and are accounted for at fair value with changes in fair value recorded in net income in the period of change. This may expose the Company to increased variability in reported earnings because the fair value of the derivative instruments can fluctuate significantly from period to period.

(1) The majority of derivative instruments held for trading have been       
    entered into for risk management purposes and all are subject to the    
    Company's risk management strategies, policies and limits. These include
    derivatives that have not been designated as hedges or do not qualify   
    for hedge accounting treatment but have been entered into as economic   
    hedges to manage the Company's exposures to market risk.                
(2) Fair values equal carrying values.                                      
(3) As at June 30, 2015.                                                    
(4) Volumes for power and natural gas derivatives are in GWh and Bcf,       
    respectively.                                                           
(5) Realized and unrealized gains and losses on held for trading derivative 
    instruments used to purchase and sell power and natural gas are included
    net in energy revenues. Realized and unrealized gains and losses on     
    interest rate and foreign exchange derivative instruments held for      
    trading are included net in interest expense and interest income and    
    other expense, respectively. The effective portion of the change in fair
    value of derivative instruments in hedging relationships is initially   
    recognized in OCI and reclassified to energy revenues, interest expense 
    and interest income and other expense, as appropriate, as the original  
    hedged item settles.                                                    
(6) All hedging relationships are designated as cash flow hedges except for 
    interest rate derivative instruments designated as fair value hedges    
    with a fair value of $3 million and a notional amount of US$750 million 
    as at June 30, 2015. For the three and six months ended June 30, 2015,  
    net realized gains on fair value hedges were $2 million and $4 million, 
    respectively, and were included in interest expense. For the three and  
    six months ended June 30, 2015, the Company did not record any amounts  
    in net income related to ineffectiveness for fair value hedges.         
(7) For the three and six months ended June 30, 2015, there were no gains or
    losses included in net income for discontinued cash flow hedges where it
    was probable that the anticipated transaction would not occur.

Offsetting of derivative instruments

The Company enters into derivative contracts with the right to offset in the normal course of business as well as in the event of default. TransCanada has no master netting agreements, however, similar contracts are entered into containing rights to offset. The Company has elected to present the fair value of derivative instruments with the right to offset on a gross basis in the balance sheet. The following table shows the impact on the presentation of the fair value of derivative instrument assets and liabilities had the Company elected to present these contracts on a net basis:

(1) Amounts available for offset do not include cash collateral pledged or

With respect to all financial arrangements, including the derivative instruments presented above as at June 30, 2015, the Company had provided cash collateral of $517 million (December 31, 2014 - $459 million) and letters of credit of $40 million (December 31, 2014 - $26 million) to its counterparties. The Company held nil (December 31, 2014 - $1 million) in cash collateral and $4 million (December 31, 2014 - $1 million) in letters of credit from counterparties on asset exposures at June 30, 2015.

Credit risk related contingent features of derivative instruments

Derivative contracts entered into to manage market risk often contain financial assurance provisions that allow parties to the contracts to manage credit risk. These provisions may require collateral to be provided if a credit-risk-related contingent event occurs, such as a downgrade in the Company's credit rating to non-investment grade.

Based on contracts in place and market prices at June 30, 2015, the aggregate fair value of all derivative instruments with credit-risk-related contingent features that were in a net liability position was $4 million (December 31, 2014 - $15 million), for which the Company had provided collateral in the normal course of business of nil (December 31, 2014 - nil). If the credit-risk-related contingent features in these agreements were triggered on June 30, 2015, the Company would have been required to provide additional collateral of $4 million (December 31, 2014 - $15 million) to its counterparties. Collateral may also need to be provided should the fair value of derivative instruments exceed pre-defined contractual exposure limit thresholds.

The Company has sufficient liquidity in the form of cash and undrawn committed revolving bank lines to meet these contingent obligations should they arise.

FAIR VALUE HIERARCHY

The Company's financial assets and liabilities recorded at fair value have been categorized into three categories based on a fair value hierarchy.


----------------------------------------------------------------------------
----------------------------------------------------------------------------
Levels     How fair value has been determined                               
----------------------------------------------------------------------------
----------------------------------------------------------------------------
Level I    Quoted prices in active markets for identical assets and         
           liabilities that the Company has the ability to access at the    
           measurement date.                                                
----------------------------------------------------------------------------
Level II   Valuation based on the extrapolation of inputs, other than quoted
           prices included within Level I, for which all significant inputs 
           are observable directly or indirectly. Inputs include published  
           exchange rates, interest rates, interest rate swap curves, yield 
           curves and broker quotes from external data service providers.   
           This category includes interest rate and foreign exchange        
           derivative assets and liabilities where fair value is determined 
           using the income approach and power and natural gas commodity    
           derivatives where fair value is determined using the market      
           approach. Transfers between Level I and Level II would occur when
           there is a change in market circumstances.                       
----------------------------------------------------------------------------
Level III  Valuation of assets and liabilities are measured using a market  
           approach based on extrapolation of inputs that are unobservable  
           or where observable data does not support a significant portion  
           of the derivatives fair value. This category includes long-dated 
           commodity transactions in certain markets where liquidity is low 
           and inputs may include long-term broker quotes. Long-term        
           electricity prices may also be estimated using a third-party     
           modeling tool which takes into account physical operating        
           characteristics of generation facilities in the markets in which 
           the Company operates. Model inputs include market fundamentals   
           such as fuel prices, power supply additions and retirements,     
           power demand, seasonal hydro conditions and transmission         
           constraints. Long-term North American natural gas prices might be
           estimated on a view of future natural gas supply and demand, as  
           well as exploration and development costs. Significant decreases 
           in fuel prices or demand for electricity or natural gas, or      
           increases in the supply of electricity or natural gas, small     
           number of transactions in markets with lower liquidity are       
           expected to or may result in a lower fair value measurement of   
           contracts included in Level III. Assets and liabilities measured 
           at fair value can fluctuate between Level II and Level III       
           depending on the proportion of the value of the contract that    
           extends beyond the time frame for which significant inputs are   
           considered to be observable. As contracts near maturity and      
           observable market data becomes available, they are transferred   
           out of Level III and into Level II.

(1) For the three and six months ended June 30, 2015, energy revenues       
    include unrealized gains attributed to derivatives in the Level III     
    category that were still held at June 30, 2015 of $11 million and $8    
    million, respectively (2014 - losses of $2 million and $2 million,      
    respectively).                                                          

A 10 per cent increase or decrease in commodity prices, with all other variables held constant, would result in a $1 million increase or decrease, respectively, in the fair value of outstanding derivative instruments included in Level III as at June 30, 2015.


                                                                            
                                                                            
                                                                            
12. Sale of GTN Pipeline to TC PipeLines, LP                                

On April 1, 2015, TransCanada completed the sale of its remaining 30 percent interest in Gas Transmission Northwest (GTN) to TC PipeLines, LP for an aggregate purchase price of US$446 million plus a purchase price adjustment of US$11 million. The US$457 million sale was comprised of US$264 million in cash, the assumption of US$98 million in proportional GTN debt and US$95 million of new Class B units of TC PipeLines, LP.


                                                                            
                                                                            
                                                                            
13. Contingencies and guarantees                                            

TransCanada and its subsidiaries are subject to various legal proceedings, arbitrations and actions arising in the normal course of business. While the final outcome of such legal proceedings and actions cannot be predicted with certainty, it is the opinion of management that the resolution of such proceedings and actions will not have a material impact on the Company's consolidated financial position or results of operations.

GUARANTEES

TransCanada and its joint venture partner on Bruce Power, BPC Generation Infrastructure Trust (BPC), have each severally guaranteed certain contingent financial obligations of Bruce B related to a lease agreement and contractor and supplier services. In addition, TransCanada and BPC have each severally guaranteed one-half of certain contingent financial obligations of Bruce A related to a sublease agreement and certain other financial obligations. The Company's exposure under certain of these guarantees is unlimited.

In addition to the guarantees for Bruce Power, the Company and its partners in certain other jointly owned entities have either (i) jointly and severally, (ii) jointly or (iii) severally guaranteed the financial performance of these entities related primarily to delivery of natural gas, PPA payments and the payment of liabilities. For certain of these entities, any payments made by TransCanada under these guarantees in excess of its ownership interest are to be reimbursed by its partners.

The carrying value of these guarantees has been included in other long-term liabilities. Information regarding the Company's guarantees is as follows:
