MESSAGE TO SHAREHOLDERS 

Production Growth, Hedging and Reduced Costs Deliver Solid Financial and Operating Results 

(cid:190)  Production for the fourth quarter of 2010 averaged 24,308 boe/d, an increase of 18% as compared to the fourth quarter of 
2009, after adjusting for non-core asset dispositions. Advantage’s daily production for 2010 exited at approximately 25,000 
boe/d, exceeding our guidance of 24,000 boe/d due to stronger than expected well performance at Glacier. The Glacier gas 
plant  expansion  is  now  completed  with  production  exceeding  100  mmcf/d  and  corporate  production  at  approximately 
30,000 boe/d.  

(cid:190)  Funds from operations for the fourth quarter of 2010 increased 6% to $40.7 million or $0.25 per share, as compared to the 
$38.5 million or $0.23 per share for the third quarter of 2010. For the year ended December 31, 2010, funds from operations 
was $175.1 million or $1.07 per share, a decrease from $197.7 million or $1.29 per share during 2009 attributed primarily to 
asset dispositions completed during the last two years.  

(cid:190)  For the three months and year ended December 31, 2010, our hedging program contributed a net gain of $9.8 million and 
$45.1 million to funds from operations, respectively. Advantage’s hedging program has helped to stabilize and enhance our 
cash flow for capital reinvestment requirements. 

(cid:190)  Operating costs for the fourth quarter of 2010 were $10.64/boe, a decrease of 3% as compared to $11.01/boe during the 
fourth quarter of 2009. Operating costs per boe for 2010 was $10.66/boe, a decrease of 12% as compared to $12.11/boe 
during  2009.  Operating  costs  per  boe  have  decreased  considerably  over  the  last  several  years  as  a  result  of  the  increasing 
contribution  of  low  cost  production  from  Glacier,  the  disposition  of  higher  cost  non-core  assets,  and  the  continued 
optimization  of  our  other  properties.  We  anticipate  corporate  operating  costs  will  decline  further  in  2011  as  a  result  of 
increased production at Glacier. 

(cid:190)  The royalty rate for 2010 as a percentage of revenue was 14.0% as compared to 14.3% in 2009. For the fourth quarter of 
2010,  Advantage’s  royalty  rate  was  12.2%  as  compared  to  13.8%  for  the  fourth  quarter  of  2009.  We  anticipate  that  our 
corporate royalty rate will decline further due to increased production from Glacier where the effective royalty rate for a new 
Glacier Montney well is anticipated to be approximately 5% over the life of the well. 

(cid:190)  Significant reductions in the average bank indebtedness during the last twelve months have led to a 31% decrease in total 

interest expense as compared to the prior year. 

(cid:190)  As at December 31, 2010, Advantage’s bank debt was $290.7 million on a credit facility of $525 million with an unutilized 
capacity of approximately $231.4 million. A total of $148.5 million of convertible debentures remain outstanding of which 
$62.3 million will mature in December 2011 and the balance of $86.2 million will mature in January 2015. 

(cid:190)  Capital expenditures during the fourth quarter of 2010 amounted to $68.9 million for a total of $223.3 million for the year 
ended  December  31,  2010.  Approximately  86%  of  our  2010  capital  program  has  been  invested  at  Glacier  where  we 
successfully completed Phase II of our development program in the second quarter of 2010. The second half 2010 capital 
spending has been focused on our Phase III development program at Glacier which consisted of drilling 28 net (28 gross) 
horizontal wells and expanding our Glacier gas plant and gathering system capacity to 100 mmcf/d. 

(cid:190)  Additional  capital  activities  during  2010  included  3  net  (3  gross)  oil  wells  at  Eyehill,  2.8  net  (3  gross)  oil  and  gas  wells  at 

Nevis, and 2.1 net (3 gross) oils wells at Sunset. 

  Glacier Production Exceeding 100 mmcf/d with Additional 100 mmcf/d of Production Capacity 

(cid:190)  Production performance at Glacier has been higher than anticipated with natural gas production averaging 53.3 mmcf/d for 

the fourth quarter of 2010 and exiting 2010 at 60 mmcf/d (10,000 boe/d), which exceeded our guidance.  

(cid:190)  Phase III activities at Glacier are now substantially complete and production is exceeding 100 mmcf/d, which has progressed 

ahead of schedule and on-budget. 

(cid:190)  An additional 100 mmcf/d (16,667 boe/d) of production capacity currently exists and additional wells will be brought on-

stream as required to offset declines and maintain production. 

(cid:190)  Optimization of drilling and completion practices combined with improved geological knowledge at Glacier has significantly 
increased the horizontal well test rates through each of our development phases. The average test rate of the Upper Montney 
wells for Phase III was 8.4 mmcf/d with an average of 13 fracs per well, surpassing our expectations.

Impressive Glacier Netbacks Enhanced by Low Cost Structure 

(cid:190)  Operating  costs  at  Glacier  are  forecast  to  decrease  from  the  $2.85/boe  ($0.48/mcf)  during  the  fourth  quarter  of  2010  to 
$1.80/boe  ($0.30/mcf)  at  100  mmcf/d  due  to  efficiencies  created  by  increasing  the  production  rate  through  Advantage’s 
100% owned Glacier gas plant and the utilization of multi-well production well pads on our contiguous land block which 
simplifies field operations.     

(cid:190)  All Montney horizontal wells drilled at Glacier after May 1, 2010 qualify for a royalty incentive of $2.7 to $3.4 million based 
on a typical Glacier Montney horizontal well (total length of 4,200 to 4,500 metres). As a result, the effective royalty rate for 
a new Glacier Montney well is anticipated to be approximately 5% over the life of the well. 

(cid:190)  The attractive royalty rates and low operating costs significantly enhances the netback and drilling economics of all of our 

Glacier Montney drilling locations as indicated below:

>66% 

(cid:190)  Based on netbacks of $3.50/mcf and $4.45/mcf, annualized cash flows are projected to be approximately $128 million and 
$162 million respectively, which are in excess of estimated capital requirements to maintain a 100 mmcf/d production rate at 
Glacier. 

(cid:190)  In summary, Glacier is a unique asset which provides the opportunity for Advantage to develop a large, scalable natural gas 
resource  play  which  contains  decades  of  drilling  inventory  and  with  one  of  the  lowest  cost  structures  in  the  Western 
Canadian Sedimentary Basin.     

Commodity Hedging Program 

(cid:190)  Advantage’s hedging program includes 25% of our forecast net natural gas production for 2011 hedged at an average price 

of Cdn$6.30 AECO per mcf and 34% of forecast net crude oil production for 2011 at Cdn$88.90 per bbl. 

(cid:190)  Additional details on our hedging program are available at our website at www.advantageog.com. 

Creation of Longview Oil Corp. 

(cid:190)  On  March  7,  2011,  Advantage  announced  that  Longview  Oil  Corp.  (“Longview”),  a  wholly-owned  subsidiary  of  the 
Corporation, filed a preliminary prospectus on March 4, 2011 for an initial public offering (the “Offering”), which is targeted 
to raise gross proceeds of $150 million prior to an over-allotment option of up to 15% of the base offering size, exercisable 
30 days following the closing of the Offering. The closing of the Offering is expected to occur in April, 2011. Concurrent 
with closing of the Offering, Longview will purchase certain oil-weighted assets from Advantage with fourth quarter 2010 
average production of 6,220 boe/d (74% oil & NGLs), proved reserves of 20.1 mmboe and proved plus probable reserves 
of 36.9 mmboe. 

(cid:190)  Advantage  will  receive  consideration  comprised  of  the  net  proceeds  of  the  Offering,  common  shares  of  Longview  and 
proceeds of $100 million to be drawn from an independent Longview credit facility to be established at closing. Advantage 
plans to use the cash proceeds from the transaction to reduce outstanding bank indebtedness. Advantage will retain an equity 
ownership  interest  of  approximately  68%  of  the  common  shares  of  Longview  (approximately  63%  if  the  over-allotment 
option is exercised in full). The transaction is conditional upon customary industry conditions including the approval of the 
Board  of  Directors  of  Advantage.  As  a  result  of  the  successful  completion  of  the  transaction,  historical  financial  and 
operating performance as well as forward-looking information may not be indicative of actual future performance. 

(cid:190)  For further details, please refer to the press release issued by Advantage on March 7, 2011 and the preliminary prospectus 
filed by Longview on March 4, 2011, which are available at www.sedar.com and Advantage’s website www.advantageog.com.

Looking Forward  

(cid:190)  Drilling results at our cornerstone Glacier property have demonstrated that our Montney development is among the top tier 
natural gas resource developments in North America. The attractive cost structure at Glacier which includes low operating 
costs  and  low  royalty  rates  combined  with  a  multi-decade  drilling  inventory  provides  a  strong  foundation  to  drive  future 
development beyond 100 mmcf/d of production. 

(cid:190)  With  the  expansion  of  Glacier  to  100  mmcf/d  now  completed,  a  review  of  well  performance,  facility  capacity  and  actual 
costs will be undertaken by Advantage to assess the timing and capital requirements for the next phase of growth at Glacier. 
(cid:190)  Advantage  will  provide  additional  corporate  guidance  and  communicate  future  development  plans  on  or  about  mid-year 

2011.

(1) Advantage’s crude oil, natural gas and natural gas liquid reserves were evaluated using Sproule’s product price forecast effective December 31, 2010 
prior to the provision for income taxes, interests, debt services charges and general and administrative expenses. It should not be assumed that the 
discounted future revenue estimated by Sproule represents the fair market value of the reserves. 

(2) Assumes that development of each property will occur, without regard to the likely availability to the Company of funding required for that 

development. 

Sproule Price Forecasts 

The present value of future net revenue at December 31, 2010 was based upon crude oil and natural gas pricing assumptions prepared 
by Sproule effective December 31, 2010. These forecasts are adjusted for reserve quality, transportation charges and the provision of 
any applicable sales contracts. The price assumptions used over the next seven years are summarized in the table below:

Net Asset Value using Sproule price and cost forecasts (Before Income Taxes) 

The following net asset value ("NAV") table shows what is normally referred to as a "produce-out" NAV calculation under which the 
current value of the Company’s reserves would be produced at forecast future prices and costs. The value is a snapshot in time and is 
based on various assumptions including commodity prices and foreign exchange rates that vary over time.

(1) Under NI 51-101, the methodology to be used to calculate FD&A costs includes incorporating changes in future development capital ("FDC") 
required  to  bring  the  proved  undeveloped  and  probable  reserves  to  production.  For  continuity,  Advantage  has  presented  herein  FD&A  costs 
calculated both excluding and including FDC.  

(2) The aggregate of the exploration and development costs incurred in the most recent financial year and the change during that year in estimated 
future  development  costs  generally  will  not  reflect  total  finding  and  development  costs  related  to  reserves  additions  for  that  year.  Changes  in 
forecast  FDC  occur  annually  as  a  result  of  development  activities,  acquisition  and  disposition  activities  and  capital  cost  estimates  that  reflect  
Sproule’s best estimate of what it will cost to bring the proved undeveloped and probable reserves on production. 

(3) In all cases, the FD&A number is calculated by dividing the identified capital expenditures by the applicable reserve additions.  Boes may be 

misleading, particularly if used in isolation.  A boe conversion ratio of 6 MCF:1 BBL is based on an energy equivalency conversion method primarily 
applicable at the burner tip and does not represent a value equivalency at the wellhead.

Management’s Discussion & Analysis 

The following Management’s Discussion and Analysis (“MD&A”), dated as of March 22, 2011, provides a detailed explanation of the 
financial  and  operating  results  of  Advantage  Oil  &  Gas  Ltd.  (“Advantage”,  the  “Corporation”,  “us”,  “we”  or  “our”)  for  the  three 
months and year ended December 31, 2010 and should be read in conjunction with the audited consolidated financial statements. The 
consolidated financial statements have been prepared in accordance with Canadian generally accepted accounting principles (“GAAP”) 
and all references are to Canadian dollars unless otherwise indicated. All per barrel of oil equivalent (“boe”) amounts are stated at a 
conversion rate of six thousand cubic feet of natural gas being equal to one barrel of oil or liquids, based on an energy equivalency 
conversion  method  primarily  applicable  at  the  burner  tip  and  does  not  represent  a  value  equivalency  at  the  wellhead.  Boes  maybe 
misleading, particularly if used in isolation. 

Forward-Looking Information 

This MD&A contains certain forward-looking statements, which are based on our current internal expectations, estimates, projections, 
assumptions and beliefs. These statements relate to future events or our future performance. All statements other than statements of 
historical  fact  may  be  forward-looking  statements.  Forward-looking  statements  are  often,  but  not  always,  identified  by  the  use  of

Corp., including the timing of completion thereof; and the effect of implementation of International Financial Reporting Standards on 
financial  results  and  the  timing  of  implementation.  In  addition,  statements  relating  to  "reserves"  or  "resources"  are  deemed  to  be 
forward-looking statements, as they involve the implied assessment, based on certain estimates and assumptions, that the resources 
and reserves described can be profitably produced in the future. 

These  forward-looking  statements  involve  substantial  known  and  unknown  risks  and  uncertainties,  many  of  which  are  beyond  our 
control,  including  changes  in  general  economic,  market  and  business  conditions;  stock  market  volatility;  changes  to  legislation  and 
regulations and how they are interpreted and enforced; changes to investment eligibility or investment criteria; our ability to comply 
with  current  and  future  environmental  or  other  laws;  actions  by  governmental  or  regulatory  authorities  including  increasing  taxes, 
changes  in  investment  or  other  regulations;  changes  in  tax  laws,  royalty  regimes  and  incentive  programs  relating  to  the  oil  and  gas 
industry; the effect of acquisitions; our success at acquisition, exploitation and development of reserves; unexpected drilling results, 
changes  in  commodity  prices,  currency  exchange  rates,  capital  expenditures,  reserves  or  reserves  estimates  and  debt  service 
requirements; the occurrence of unexpected events involved in the exploration for, and the operation and development of, oil and gas 
properties; hazards such as fire, explosion, blowouts, cratering, and spills, each of which could result in substantial damage to wells, 
production  facilities,  other  property  and  the  environment  or  in  personal  injury;  changes  or  fluctuations  in  production  levels; 
competition from other producers; the lack of availability of qualified personnel or management; individual well productivity; ability to

Advantage Oil & Gas Ltd. - 10 

 
 
Management  has  included  the  above  summary  of  assumptions  and  risks  related  to  forward-looking  information  provided  in  this 
MD&A in order to provide shareholders with a more complete perspective on Advantage's future operations and such information 
may not be appropriate for other purposes. Advantage’s actual results, performance or achievement could differ materially from those 
expressed  in,  or  implied  by,  these  forward-looking  statements  and,  accordingly,  no  assurance  can  be  given  that  any  of  the  events 
anticipated by the forward-looking statements will transpire or occur, or if any of them do so, what benefits that Advantage will derive 
there from. Readers are cautioned that the foregoing lists of factors are not exhaustive. These forward-looking statements are made as 
of  the  date  of  this  MD&A  and  Advantage  disclaims  any  intent  or  obligation  to  update  publicly  any  forward-looking  statements, 
whether as a result of new information, future events or results or otherwise, other than as required by applicable securities laws. 

This  MD&A  discusses  historical  financial  and  operating  performance  as  well  as  forward-looking  information  for  the  Corporation 
excluding  any  potential  impacts  that  may  occur  due  to  the  successful  completion  of  the  transaction  with  Longview  Oil  Corp.  (see 
section  “Creation  of  Longview  Oil  Corp.”).  As  a  result,  historical  financial  and  operating  performance  as  well  as  forward-looking 
information may not be indicative of actual future performance. 

Non-GAAP Measures 

The  Corporation  discloses  several  financial  measures  in  the  MD&A  that  do  not  have  any  standardized  meaning  prescribed  under 
GAAP. These financial measures include funds from operations and cash netbacks. Management believes that these financial measures 
are  useful  supplemental  information  to  analyze  operating  performance  and  provide  an  indication  of  the  results  generated  by  the 
Corporation’s principal business activities prior to the consideration of how those activities are financed or how the results are taxed. 
Investors should be cautioned that these measures should not be construed as an alternative to net income, cash provided by operating 
activities  or  other  measures  of  financial  performance  as  determined  in  accordance  with  GAAP.  Advantage’s  method  of  calculating 
these  measures  may  differ  from  other  companies,  and  accordingly, they  may  not  be  comparable  to  similar  measures  used  by  other 
companies. 

Funds from operations, as presented, is based on cash provided by operating activities before expenditures on asset retirement and 
changes  in  non-cash  working capital.  Cash  netbacks are dependent  on  the  determination of  funds  from operations  and  include  the 
primary cash revenues and expenses on a per boe basis that comprise funds from operations. Funds from operations reconciled to 
cash provided by operating activities is as follows:

    (1) Based on basic weighted average shares outstanding.

Our financial and operating results during 2009 and 2010 have been impacted by dispositions completed during these years. In July 
2009 we closed two major asset dispositions for net proceeds of $242.1 million representing production of approximately 8,100 boe/d. 
On May 31 and June 3, 2010, we closed two additional asset dispositions of non-core natural gas weighted properties for net proceeds 
of  $66.5  million  and  representing  production  of  approximately  1,700  boe/d.  The  net  proceeds  from  the  various  dispositions  were 
utilized to reduce outstanding debt. As a result of the dispositions, total funds from operations decreased for the three months and 
year ended December 31, 2010 compared to the same periods of 2009 with all revenues and expenses generally impacted. 

For the year ended December 31, 2010 we continued to realize significant gains on derivatives which amounted to $45.1 million that 
has helped to offset the continued weak natural gas prices and positively impact funds from operations. Hedging gains in 2010 were 
lower than 2009 as we had a lower percentage of natural gas production hedged at lower average prices. Funds from operations has 
also  benefited  during  this  year  from  higher  crude  oil  prices  and  continued  cost  reductions,  such  as  operating  costs  and  interest 
expense. Unfortunately, natural gas prices still remain weak and pose a continuing challenge to the entire natural gas industry. When 
comparing  the  current  quarter  to  the  third  quarter  of  2010,  our  funds  from  operations  per  boe  increased  6%  to  $18.21/boe  from 
$17.19/boe as both production and crude oil prices increased, partially offset by the impact of lower natural gas prices. Funds from 
operations per share decreased from 2009 due to the decrease in total funds from operations and the increase in shares outstanding 
attributable to 17 million shares issued in July 2009 as a result of an equity offering. Cash provided by operating activities has increased 
during  2010  as  compared  to  the  prior  year  due  to  the  decrease  in  funds  from  operations  being  more  than  offset  by  increases  in 
working capital deficit. 

As  a  result  of  asset  dispositions  completed  in  2009  and  2010  and  changes  in  commodity  prices,  historical  financial  and 
operating performance may not be indicative of actual future performance. 

The primary factor that causes significant variability of the Corporation’s cash provided by operating activities, funds from operations, 
and  net  income  is  commodity  prices.  Refer  to  the  section  “Commodity  Prices  and  Marketing”  for  a  more  detailed  discussion  of 
commodity prices and our price risk management.

Revenue, excluding hedging, was negatively impacted for the three months and year ended December 31, 2010, as compared to 2009, 
primarily due to lower production attributable to our asset dispositions that closed in the third quarter of 2009 and the second quarter 
of 2010. Production net of asset dispositions increased 16% for the year ended December 31, 2010 as compared to 2009 as a result of

our successful exploration and development activities. Natural gas revenue for 2010 benefited from significant increases to production 
at our Montney natural gas resource play at Glacier, Alberta where we have increased production capacity by 140% since December 
31, 2009. Additional increases in production have been realized now that our facilities and infrastructure expansion work have been 
completed in the first quarter of 2011. Total revenue was also positively impacted by crude oil and NGLs prices, excluding hedging, 
that  have  been  higher  for  2010  as  compared  to  2009  and  partially  offset  reduced  production  from  asset  dispositions.  However, 
revenue  has  continued  to  be  adversely  impacted  by  natural  gas  prices  that  have  been  weak  during  the  last  two  years  due  to  many 
factors,  including  the  recession  in  the  North  American  economy  that  has  generally  reduced  energy  demand  and  higher  North 
American natural gas production, both of which have maintained relatively high natural gas inventory levels. 

Given  the  low  natural  gas  price  environment,  our  commodity  price  risk  management  program  has  delivered  realized  natural  gas 
hedging gains of $12.9 million and $55.4 million for the three months and year ended December 31, 2010, respectively. As crude oil 
prices continued to strengthen throughout 2010, we realized crude oil hedging losses of $3.1 million and $10.2 million for the three 
months and year ended December 31, 2010, respectively. The Corporation enters derivative contracts whereby realized hedging gains 
and losses partially offset commodity price fluctuations, which can positively or negatively impact revenue. The realized natural gas 
hedging gains have been significant and helped us stabilize cash flows and ensure that our capital expenditure program is substantially 
funded by such cash flows.

Average daily production during the fourth quarter of 2010 increased 8% above the same period of 2009, with natural gas production 
increasing 26% while being offset by decreases in crude oil and NGLs production. Production from the fourth quarter of 2009 also 
included  approximately  1,990  boe/d  related  to  assets  disposed  in  2010.  After  excluding  production  from  these  asset  dispositions, 
Advantage’s average daily production for the fourth quarter of 2010 increased approximately 18%, as compared to the same period of 
2009. Average daily production for the fourth quarter of 2010 was comparable to the 24,287 boe/d reported in the third quarter of 
2010 and our exit daily production rate for December 31, 2010 was approximately 25,000 boe/d, exceeding our guidance of exiting the 
year at 24,000 boe/d. Average annual production for 2010 was lower than 2009 due to the impact of asset dispositions which was 
partially offset by production growth at Glacier, Alberta. During the second quarter of 2010 our new 100% working interest gas plant 
(“Glacier gas plant”) was brought on-stream ahead of schedule with production rates exceeding 50  mmcf/d (8,300 boe/d). Due to 
stronger than expected well performance, we were able to further increase Glacier production ending the year exceeding 60 mmcf/d 
(10,000  boe/d).  This  year  represented  another  milestone  in  the  development  of  our  significant  Montney  reserves  and  resource 
potential at Glacier by increasing production capacity 140%. 

Phase III of our Glacier development project has progressed ahead of schedule and on-budget with production now exceeding 100 
mmcf/d (16,667 boe/d). We have been very active in drilling, testing and completing wells at Glacier during the last half of 2010 and 
into 2011. An additional 100 mmcf/d (16,667 boe/d) of production capacity currently exists and additional wells will be brought on-
stream as required to offset declines and maintain production. We expect corporate production to average approximately 26,600 to 
27,200 boe/d for the first half of 2011 since completing the 100 mmcf/d Glacier gas plant expansion.

Realized  natural  gas  prices,  excluding  hedging,  were  18%  lower  for  the  three  months  ended  and  3%  lower  for  the  year  ended 
December  31,  2010  as  compared  to  the  same  periods  of  2009.  Our  realized  natural  gas  prices,  excluding  hedging,  for  this  quarter 
decreased  1%  from the $3.51/mcf  realized during the third  quarter  of  2010.  Although  natural  gas  prices  have continued  to  remain 
weak, our commodity hedging strategy has resulted in realized natural gas prices, including hedging, that well exceed current market 
prices. Our realized natural gas prices, including hedging, have decreased during 2010 as compared to 2009 as we have less natural gas 
production hedged for this year at lower average prices. Nevertheless, our hedging program has significantly mitigated the negative 
impact from lower natural gas prices and has reduced the volatility of our cash flows. 

During  2009  and  2010,  natural  gas  prices  have  remained  low  from  continued  high  US  domestic  natural  gas  production  that  has 
increased supply and the ongoing weaker North American economy that has negatively impacted demand. These factors have resulted 
in generally higher inventory during these years and has placed considerable downward pressure on natural gas prices. Heading into 
the 2009/2010 winter season, we saw strong inventory withdraws which helped to modestly strengthen prices relative to the prior lows 
experienced  during  the  majority  of  2009.  However,  as  we  exited  the  winter,  natural  gas  prices  significantly  decreased  and  have 
remained weak throughout 2010. During the 2010/2011 winter we have seen respectable storage withdraws that has helped to reduce 
natural gas inventory to approximately the five-year average. Nevertheless, natural gas prices continue to remain weak as we exit the 
winter. We continue to believe in the longer-term price support for natural gas as reduced drilling for new resource based natural gas 
supplies  and  conventional  natural  gas  will  eventually  reduce  the  supply  levels.  We  continue  to  monitor  these  market  developments 
closely and will be proactive in implementing an appropriate hedging strategy to mitigate the volatility in our cash flow as a result of 
fluctuations in natural gas prices.

Realized crude oil and NGLs prices, excluding hedging, increased 10% and 21% for the three months and year ended December 31, 
2010,  as  compared  to  the  same  periods  of  2009.  As  compared  to  the  third  quarter  of  2010,  realized  crude  oil  and  NGLs  prices, 
excluding  hedging,  have  increased  12%  for  the  fourth  quarter  of 2010.  Advantage’s  realized  crude  oil  price  may  not  change  to  the 
same extent as West Texas Intermediate (“WTI”), due to changes in the $US/$Canadian exchange rate and changes in Canadian crude 
oil differentials relative to WTI. 

The  price  of  WTI  fluctuates  based  on  worldwide  supply  and  demand  fundamentals.  There  has  been  significant  price  volatility 
experienced over the last several years whereby WTI reached historic high levels in the first half of 2008, followed by a record decline 
in  the  latter  half  of  the  year  and  into  early  2009,  the  result  of  demand  destruction  brought  on  by  the  global  recession.  There  was 

Advantage Oil & Gas Ltd. - 14 

 
 
         
         
         
         
 
 
 
improvement during the last half of 2009 which continued during 2010 and significantly escalated into 2011 primarily influenced by 
middle-east  civil  unrest,  with  WTI  currently  trading  at  approximately  US$104/bbl.  However,  we  have  also  seen  a  constant 
strengthening of the $US/$Canadian exchange rate during these years such that our increase in realized price has been less than the 
improvement in WTI. We continue to believe that the long-term pricing fundamentals for crude oil will remain strong with supply 
management by the OPEC cartel and strong relative demand from many developing countries, such as China and India. 

Commodity Price Risk 

The Corporation’s financial results and condition will be dependent on the prices received for oil and natural gas production. Oil and 
natural gas prices have fluctuated widely and are determined by economic and political factors. Supply and demand factors, including 
weather and general economic conditions as well as conditions in other oil and natural gas regions, impact prices. Any movement in oil 
and natural gas prices could have an effect on the Corporation’s financial condition and performance. Advantage has an established 
financial hedging strategy and may manage the risk associated with changes in commodity prices by entering into derivative contracts. 
Although these commodity price risk management activities could expose Advantage to losses or gains, entering derivative contracts 
helps us to stabilize cash flows and ensures that our capital expenditure program is substantially funded by such cash flows. To the 
extent that Advantage engages in risk management activities related to commodity prices, it will be subject to credit risk associated 
with counterparties with which it contracts. Credit risk is mitigated by entering into contracts with only stable, creditworthy parties and 
through frequent reviews of exposures to individual entities. In addition, the Corporation only enters into derivative contracts with 
major banks that are members of our credit facility syndicate and international energy firms to further mitigate associated credit risk. 
Our credit facilities also prohibit the Corporation from entering into any derivative contract where the term of such contract exceeds 
three  years.  Further,  the  aggregate  of  such  contracts  cannot  hedge  greater  than  60%  of  total  estimated  petroleum  and  natural  gas 
production over two years and 50% over the third year. 

We  have  historically  been  active  in  entering  financial  contracts  to  protect  future  cash  flows  and  currently  the  Corporation  has  the 
following derivatives in place:

(1)  Approximate  production  hedged  is  based  on  our  estimated  average  production  by  quarter,  net  of  estimated  royalty 

payments. 

For the year ended December 31, 2010, we recognized in income a net realized derivative gain of $45.1 million (December 31, 2009 - 
$86.5  million  net  realized  derivative  gain)  on  settled  derivative  contracts  as  a  result  of  average  market  prices  decreasing  below  our 
established  average  hedge  prices.  Our  net  realized  derivative  gain  has  decreased  during  2010  as  compared  to  2009  as  we  have  less 
natural  gas  production  hedged  for  this  year  at  lower  average  prices  and  we  realized  losses  on  our  crude  oil  hedges  as  WTI  prices 
increased. However, our successful commodity price risk management program continued to realize significant gains on derivatives for 
the year ended December 31, 2010 that has helped to offset the continued weak natural gas prices and positively impact funds from 
operations.  As  at  December  31,  2010,  the  fair  value  of  the  derivative  contracts  outstanding  and  to  be  settled  was  a  net  asset  of 
approximately $22.6 million, an increase of $5.4 million from the $17.2 million net asset recognized as at December 31, 2009. For the 
year ended December 31, 2010, this $5.4 million increase was recognized in income as an unrealized derivative gain (December 31, 
2009 – $23.7 million unrealized derivative loss). The valuation of the derivatives is the estimated fair value to settle the contracts as at 
December  31,  2010  and  is  based  on  pricing  models,  estimates,  assumptions  and  market  data  available  at  that  time.  As  such,  the 
recognized  amounts  are  not  cash  and  the  actual  gains  or  losses  realized  on  eventual  cash  settlement  can  vary  materially  due  to 
subsequent fluctuations in commodity prices and foreign exchange rates as compared to the valuation assumptions. The Corporation 
does not apply hedge accounting and current accounting standards require changes in the fair value to be included in the consolidated 
statements of income (loss) and comprehensive income (loss) as an unrealized derivative gain or loss with a corresponding derivative 
asset and liability recorded on the balance sheet. These derivative contracts will settle in 2011 corresponding to when the Corporation 
will receive revenues from production.

Advantage pays royalties to the owners of mineral rights from which we have leases. The Corporation currently has mineral leases with 
provincial governments, individuals and other companies. Royalty expense includes the impact of gas cost allowance (“GCA”), which 
is a reduction of royalties payable to the Alberta Provincial Government to recognize capital and operating expenditures incurred in 
the gathering and processing of their share of natural gas production and does not generally fluctuate with natural gas prices. Total 
royalties  paid  and  royalties  as  a  percentage  of  revenue  decreased  for  the  three  months  ended  December  31,  2010  compared  to  the 
same  period  of  2009  due  to  lower  natural  gas  prices.  For  the  year  ended December  31,  2010,  total  royalties  paid  decreased  due  to 
lower  revenue  from  reduced  production  attributable  to  our  asset  dispositions  while  royalties  as  a  percentage  of  revenue  was 
comparable.  

Our  average  corporate  royalty  rates  are  significantly  impacted  by  the  Alberta  Provincial  Government’s  royalty  framework  that  was 
revised effective January 1, 2009 for conventional oil, natural gas and oil sands whereby Alberta royalties are affected by depths, well 
production rates, and commodity prices. Additionally, the Alberta Provincial Government implemented a number of drilling incentive 
programs with reduced royalty rates over a period of time for qualifying wells. The majority of our wells brought on production since 
April 1, 2009 qualify and benefit from a 5% royalty rate on the first 500 mmcf produced or one-year, whichever occurs first, and a 
drilling credit of $200 per metre drilled that reduces capital spending. The drilling credit incentives are effective for qualifying wells 
drilled  and  brought  on  production  from  April  1,  2009  to  March  31,  2011  while  the  reduced  5%  royalty  rate  program  was  made  a 
permanent  incentive  as  of  May  1,  2010.  The  Alberta  Provincial  Government  also  made  changes  in  the  Natural  Gas  Deep  Drilling 
Program  (“NGDDP”)  which  reduces  the  vertical  depth  requirement  to  2,000  metres  (from  2,500  metres)  and  makes  the  program 
permanent. As a result, all of our Montney horizontal wells at Glacier drilled after May 1, 2010 will qualify for the NGDDP which is 
estimated to provide an additional royalty incentive of $2.7 to $3.4 million for a typical horizontal well (a typical Advantage horizontal 
well  at  Glacier  is  4,200  to  4,500  metres  in  total  length).  This  royalty  incentive  results  in  an  estimated  5  to  7%  royalty  rate  for  all 
Montney horizontal wells for the life of the well. This significantly lowers the natural gas price threshold required to drill economic 
wells and substantially improves the value of future reserves and upside potential at Glacier. 

We expect our corporate royalty rate to be in the range of 13% to 15% for the first half of 2011. Alberta royalty rates will continue to 
fluctuate based on commodity prices, individual well productivity, and our ongoing capital development plans.

Total operating costs increased 4% for the three months ended December 31, 2010 and decreased 21% for the year ended December 
31, 2010 as compared to the same periods of 2009. The reduction in total operating costs for 2010 has been primarily due to the sale 
of  higher  cost  assets,  increased  production  from  Glacier  and  benefits  of  our  ongoing  optimization  program.  Total  operating  costs 
increased modestly during the fourth quarter of 2010 as compared to the same period of 2009 due to an 8% increase in corporate 
production and the impact of cold weather operations. Operating costs per boe decreased 12% from 2009 to 2010 and we anticipate 
corporate operating costs will decline further in 2011 as a result of increasing production at Glacier. Operating costs at Glacier during 
the fourth quarter of 2010 decreased to approximately $2.85/boe ($0.48/mcf) which has significantly improved the netbacks realized 
from our Montney gas production. We estimate that operating costs at Glacier will be further reduced to a target of approximately 
$1.80/boe  ($0.30/mcf)  at  100  mmcf/d  due  to  the  efficiencies  created  by  increasing  the  production  rate  through  our  100%  owned 
Glacier gas plant. We will seek further opportunities to improve our operating cost structure and expect corporate operating costs for 
the first half of 2011 to be between $8.50 and $9.00/boe.

Cash  general  and  administrative  (“G&A”)  expense  for  the  three  months  and  year  ended  December  31,  2010  has  decreased  as 
compared to the same periods of 2009 due to incremental costs incurred in 2009 associated with the asset dispositions (approximately 
$1.8 million for severance costs) and costs incurred for our corporate conversion and reorganization (approximately $2.5 million). 

Non-cash  G&A  expense  for  the  three  months  ended  December  31,  2010  decreased  10%  but  increased  27%  for  the  year  ended 
December  31,  2010,  as  compared  to  the  same  periods  of  2009.  Non-cash  G&A  expense  is  primarily  comprised  of  Advantage’s 
Restricted Share Performance Incentive Plan (“RSPIP” or the “Plan”) as approved by the shareholders with the purpose to retain and 
attract employees, to reward and encourage performance, and to focus employees on operating and financial performance that results 
in  lasting  shareholder  return.  The  Plan  authorizes  the  Board  of  Directors  to  grant  restricted  shares  to  service  providers  of  the 
Corporation,  including  directors,  officers,  employees  and  consultants.  The  number  of  restricted  shares  granted  is  based  on  the 
Corporation’s share price return for a twelve-month period and compared to the performance of a peer group approved by the Board 
of  Directors.  The  share  price return  is calculated  at  the  end  of  each  and  every  quarter and  is  primarily  based  on  the  twelve-month 
change  in  the  share  price.  If  the  share  price return for  a twelve-month  period  is  positive, a  restricted  share grant  will  be  calculated 
based on the return. If the share price return for a twelve-month period is negative, but the return is still within the top two-thirds of 
the approved peer group performance, the Board of Directors may grant a discretionary restricted share award. Compensation cost 
related to the Plan is recognized as equity-based compensation expense within G&A expense over the service period and incorporates 
the  share  grant  price,  the  estimated  number  of  restricted  shares  to  vest,  and  certain  management  estimates.  For  the  year  ended 
December 31, 2010, we granted 2,547,020 restricted shares at an average grant price of $6.93 per restricted share and recognized $16.1 
million of equity-based compensation expense, including a non-cash amount of $13.4 million, related to restricted shares granted to 
service providers. During the year ended December 31, 2010 we issued 1,346,481 shares to service providers in accordance with the 
vesting provisions of the Plan. As at December 31, 2010, 2,925,868 restricted shares remain unvested and will vest to service providers 
over the next two years with a total of $8.1 million in compensation cost to be recognized over the future service periods.

In  2006,  Advantage  Energy  Income  Fund  (the  “Fund”)  and  Advantage  Investment  Management  Ltd.  (the  “Manager”)  reached  an 
agreement to internalize a pre-existing management contract arrangement. As part of the agreement, the Fund agreed to purchase all 
of  the  outstanding  shares  of  the  Manager  pursuant  to  the  terms  of  the  arrangement,  thereby  eliminating  the  management  fee  and 
performance  incentive  effective  April  1,  2006.  The  Trust  Unit  consideration  issued  in  exchange  for  the  outstanding  shares  of  the 
Manager  was  placed  in  escrow  for  a  three-year  period  and  was  deferred  and  amortized  into  income  as  management  internalization 
expense over the specific vesting periods. As of June 23, 2009, the final Trust Units held in escrow vested and there is no subsequent 
management internalization expense recognized.

Total interest expense decreased 33% for the three months and 31% for the year ended December 31, 2010 as compared to 2009. 
During  the  first  half  of  2009,  Advantage  experienced  significantly  lower  average  interest  rates  as  bank  lending  rates  declined  in 
response to rate reductions enacted by central banks to stimulate the economy. This reduced interest expense was partially offset by 
additional interest expense on a higher average debt balance during that period. In June 2009 our credit facility was renewed and was 
subject  to  generally  higher  basis  point  and  stamping  fee  adjustments  as  was  typically  applied  by  financial  institutions  at  that  time. 
Therefore, our average effective interest rate during 2010 has been slightly higher than 2009; however, this was significantly offset by 
lower interest expense on the reduced average bank indebtedness that resulted from proceeds on various asset dispositions and both 
the equity financing and convertible debenture issuance during the periods. Bank indebtedness has increased in the fourth quarter of 
2010 as expected due to progress of the Phase III capital expenditure program at Glacier. Our revolving credit facility was renewed in 
June 2010 and is subject to basis point and stamping fee adjustments ranging from 1.25% to 3.75%, depending on the Corporation’s 
debt to cash flow ratio. The Corporation’s interest rates are primarily based on short term bankers acceptance rates plus a stamping 
fee. We monitor the debt level to ensure an optimal mix of financing and cost of capital that will provide a maximum return to our 
shareholders. Our current credit facilities have been a favorable financing alternative with an effective interest rate of 5.0% for the year 
ended December 31, 2010.

Interest on convertible debentures for the three months and year ended December 31, 2010 has decreased compared to 2009 due to 
the maturity of the 8.25% debentures on February 1, 2009, the 8.75% debentures on June 30, 2009, the 7.50% debentures on October 
1, 2009, and the 6.50% debentures on June 30, 2010. The reduced interest has been partially offset by additional interest on our 5.00% 
convertible  debentures  that  were  issued  on  December  31,  2009.  Accretion  on  convertible  debentures  has  increased  for  the  three 
months  and  year  ended  December  31,  2010  as  compared  to  the  same  periods  of  2009  due to  the  higher  accretion  expense  on  the 
5.00%  convertible  debentures  as  a  result  of  the  greater  value  assigned  to  the  equity  component  of  the  debenture  representing  the 
conversion option available to debentureholders.

Depletion and depreciation of petroleum and natural gas properties is provided on the “unit-of–production” method based on total 
proved reserves. Accretion represents the increase in the asset retirement obligation liability each reporting period due to the passage 
of time. The depletion, depreciation and accretion (“DD&A”) provision has decreased for the three months and year ended December 
31, 2010 compared to 2009 due to reduced production from the asset dispositions that closed during the periods and a lower average 
rate  of  DD&A  per  boe.  Our  DD&A  rate  per  boe  has  decreased  considerably  during  2010  as  compared  to  2009  due  to  a  higher 
proportion of proved reserves as compared to capital expenditures and future development capital. This change has occurred primarily 
due to our successful exploration and development activities, particularly at Glacier, that contributed to a 33% increase in corporate 
proved reserves. 

Taxes 

Current taxes paid or payable for the year  ended December 31, 2010 amounted to $1.3 million, comparable to the expense for the 
same period of 2009. Current taxes primarily represent Saskatchewan resource surcharge, which is based on the petroleum and natural 
gas revenues earned within the province of Saskatchewan. 

Future  income  taxes  arise  from  differences  between  the  accounting  and  tax  bases  of  our  assets  and  liabilities.  For  the  year  ended 
December 31, 2010, the Corporation recognized a total future income tax reduction of $8.2 million compared to a future income tax 
reduction of $10.9 million for the same period of 2009. The future income tax reduction for 2010 is comparable to 2009, although the 
loss before taxes for the prior year was significantly higher, due to a $23.0 million future income tax expense impact recognized in the 
third  quarter  of  2009  related  to  the  corporate  conversion  that  was  completed  during  that  period.  As  at  December  31,  2010,  the 
Corporation  had  a  total  future  income  tax  liability  balance  of  $35.3  million,  compared  to  $43.5  million  at  December  31,  2009. 
Canadian generally accepted accounting principles require that a future income tax liability be recorded when the book value of assets 
exceeds the balance of tax pools. 

The Corporation has approximately $1.6 billion in tax pools and deductions at December 31, 2010, which can be used to reduce the 
amount of taxes payable by Advantage. The estimated tax pools in place at December 31, 2010 are as follows:

Net loss and net loss per share increased for the three months ended December 31, 2010 but decreased for the year ended December 
31, 2010, as compared to the same periods of 2009. During the third quarter of 2009 and the second quarter of 2010 we completed 
several  asset  dispositions  that  generally  reduced  all  revenues  and  expenses  as  compared  to  the  prior  year.  However,  with  our  new 
100% working interest Glacier gas plant that came on-stream during the second quarter of 2010, our corporate natural gas production 
has increased 26% as compared to the fourth quarter of 2009 thereby exceeding disposed production. Revenue for 2010 was positively 
impacted by higher crude oil prices as compared to 2009 but our major challenge continues to be the natural gas price environment 
that has remained weak and adversely impacts revenue, which generally results in our recognized net loss regardless of other significant 
positive accomplishments during the year. Low revenues were partially mitigated by our commodity hedging program that resulted in a 
net realized derivative gain of $45.1 million for the year ended December 31, 2010 and a non-cash unrealized derivative gain of $5.4 
million relating to the valuation of commodity hedging contracts outstanding as at December 31, 2010 that will not settle until 2011. 
Our realized derivative gain has decreased during 2010 as compared to 2009 as we have less natural gas production hedged for this 
year at lower average prices and we realized losses on our crude oil hedges as WTI prices increased. We continue to experience low 
royalty rates due to weak natural gas prices and Alberta Provincial royalty reduction incentive plans relative to our capital development 
program.  Operating  costs  have  continued  to  improve  through  increased  production  volumes  at  Glacier,  divestment  of  higher  cost 
non-core assets and an aggressive optimization program that continues to demonstrate positive benefits. We anticipate that corporate 
operating  costs  will  further  improve  as  a  result  of  lower  cost  production  from  our  Glacier  property  that  is  currently  producing  in 
excess of 100 mmcf/d. Our net loss for 2010 is also lower relative to 2009 due to significant costs incurred during the third quarter of 
2009 attributed to the corporate conversion, including the recognition of several one-time costs in G&A expense and a future income 
tax expense of $23.0 million.

Funds from operations decreased in total for the three months and year ended December 31, 2010 compared to the same periods of 
2009  primarily  due  to  our  asset  dispositions  completed  in  the  third  quarter  of  2009  and  the  second  quarter  of  2010  that  generally 
impacted all revenues and expenses. However, funds from operations have been positively impacted during 2010 due to completion of 
the Glacier gas plant whereby we have realized production rates exceeding 50 mmcf/d (8,300 boe/d). Due to stronger than expected 
well performance, we were able to exit 2010 with Glacier production exceeding 60 mmcf/d (10,000 boe/d). Funds from operations 
per boe or cash netbacks decreased when compared to 2009 primarily due to lower realized derivative gains as we have less natural gas 
production  hedged  for  2010  at  lower  average  prices.  However,  our  successful  commodity  price  risk  management  program  has  still 
enabled us to realize significant gains on derivatives of $45.1 million for the year ended December 31, 2010 that has helped to offset

the continued weak natural gas prices and positively impact funds from operations. Funds from operations has also benefited during 
this year from higher crude oil prices and continued cost reductions. Unfortunately, natural gas prices still remain weak and pose a 
continuing challenge to the entire natural gas industry. Operating costs per boe decreased as we continue to realize benefits from our 
divestment of higher cost assets and the addition of lower cost production due to the completion of our Glacier gas plant. Interest 
expense has also continued to decrease as we utilized proceeds from the various asset dispositions and both the equity financing and 
convertible debenture issuance during the periods to repay bank indebtedness and maturing convertible debentures. When comparing 
the current quarter to the third quarter of 2010, our funds from operations per boe increased 6% to $18.21/boe from $17.19/boe as 
both production and crude oil prices increased, partially offset by the impact of lower natural gas prices. 

Contractual Obligations and Commitments 

The Corporation has contractual obligations in the normal course of operations including purchases of assets and services, operating 
agreements, transportation commitments, sales contracts, bank indebtedness and convertible debentures. These obligations are of a 
recurring and consistent nature and impact cash flow in an ongoing manner. The following table is a summary of the Corporation’s 
remaining  contractual  obligations  and  commitments.  Advantage  has  no guarantees  or  off-balance  sheet  arrangements  other  than  as

(1)  The Corporation’s bank indebtedness does not have specific maturity dates. It is governed by a credit facility agreement with a syndicate of financial institutions. 

Under the terms of the agreement, the facility is reviewed annually, with the next review scheduled in June 2011. The facility is revolving, and is extendible at each 

annual review for a further 364 day period at the option of the syndicate. If not extended, the credit facility is converted at that time into a one-year term facility, 

with the principal payable at the end of such one-year term. Management fully expects that the facility will be extended at each annual review.    

(2)  As at December 31, 2010, Advantage had $148.5 million convertible debentures outstanding (excluding interest payable during the various debenture terms). Each 

series of convertible debentures are convertible to shares based on an established conversion price. All remaining obligations related to convertible debentures can 

be settled through the payment of cash or issuance of shares at Advantage’s option.

Advantage  monitors  its  capital  structure  and  makes  adjustments  according  to  market  conditions  in  an  effort  to  meet  its  objectives 
given the current outlook of the business and industry in general. The capital structure of the Corporation is composed of working 
capital, bank indebtedness, convertible debentures, capital lease obligations and shareholders’ equity. Advantage may manage its capital 
structure by issuing new shares, repurchasing outstanding shares, obtaining additional financing either through bank indebtedness or 
convertible  debenture  issuances,  refinancing  current  debt,  issuing  other  financial  or  equity-based  instruments,  declaring  a  dividend, 
implementing  a  dividend  reinvestment  plan,  adjusting  capital  spending,  or  disposing  of  assets.  The  capital  structure  is  reviewed  by 
Management and the Board of Directors on an ongoing basis. 

Management  of  the  Corporation’s  capital  structure  is  facilitated  through  its  financial  and  operational  forecasting  processes.  The 
forecast of the Corporation’s future cash flows is based on estimates of production, commodity prices, forecast capital and operating 
expenditures, and other investing and financing activities. The forecast is regularly updated based on new commodity prices and other 
changes, which the Corporation views as critical in the current environment. Selected forecast information is frequently provided to 
the Board of Directors. This continual financial assessment process further enables the Corporation to mitigate risks. The Corporation 
continues to satisfy all liabilities and commitments as they come due. 

The  current  economic  situation  has  placed  considerable  pressure  on  commodity  prices.  Natural  gas  prices  have  remained  weak 
throughout  2009  and  2010  due  to  the  ailing  economy  as  well  as  high  inventory  levels  with  AECO  gas  presently  trading  at 
approximately  $3.80/mcf.  Crude  oil  has  improved  since  early  2009  and  has  continued  to  increase  with  WTI  at  approximately 
US$104/bbl. The outlook for the Corporation from prolonged weak natural gas prices would be reductions in operating netbacks and 
funds from operations. Management has partially mitigated this risk through our commodity hedging program but the lower natural 
gas price environment has still had a significant negative impact. In order to strengthen our financial position and balance our cash 
flows,  in  2009  we  completed  an  equity  financing,  two  asset  dispositions,  and  issued  5.00%  convertible  debentures  and  in  2010  we 
completed  two  additional  asset  dispositions.  These  steps  have  allowed  us  to  repay  significant  bank  indebtedness  and  maturing 
convertible debentures and also enabled us to focus capital spending on our Glacier Montney natural gas resource play. However, we 
continue  to  be  very  cognizant  of  improving  our  financial  flexibility  in  the  current  environment  and  have  initiated  a  process  to  sell 
certain oil-weighted assets to Longview with an anticipated closing date in April, 2011. The net proceeds from the Transaction will be 
utilized to further repay bank indebtedness. 

We  believe  that  Advantage  has  implemented  strategies  to  protect  our  business  as  much  as  possible  in  the  current  industry  and 
economic  environment.  We  have  implemented  a  strategy  to  balance  funds  from  operations  and  our  capital  program  expenditure 
requirements. A successful hedging program was also executed to help reduce the volatility of funds from operations. However, we are 
still exposed to risks as a result of the current economic situation. We continue to closely monitor the possible impact on our business 
and strategy, and will make adjustments as necessary with prudent management. 

Shareholders’ Equity and Convertible Debentures 

Advantage  has  utilized  a  combination  of  equity,  convertible  debentures  and  bank  debt  to  finance  acquisitions  and  development 
activities. 

As  at  December  31,  2010,  the  Corporation  had  164.1  million  shares  outstanding.  During  2010  we  have  issued  1,346,481  shares  to 
employees in accordance with the vesting provisions of the RSPIP. As at March 22, 2011, shares outstanding have increased to 164.5 
million. 

The Corporation had $148.5 million convertible debentures outstanding at December 31, 2010 that were immediately convertible to 
13.0 million shares based on the applicable conversion prices (December 31, 2009 - $218.5 million outstanding and convertible to 15.8 
million shares). During the year ended December 31, 2010, there were no conversions of debentures. The principal amount of 6.50% 
convertible debentures matured on June 30, 2010 and was settled with $69.9 million in cash. As at March 22, 2011, the convertible 
debentures  outstanding  have  not  changed  from  December  31,  2010.  We  have  $62.3  million  of  7.75%  and  8.00%  debentures  that 
mature  in  December  2011  and  $86.2  million  of  5.00%  debentures  that  mature  in  January  2015.  These  obligations  can  be  settled 
through the payment of cash or issuance of shares at Advantage’s option. 

Bank Indebtedness, Credit Facility and Other Obligations 

At  December  31,  2010,  Advantage  had  bank  indebtedness  outstanding  of  $290.7  million.  Bank  indebtedness  has  increased  $40.4 
million  since  December  31,  2009,  primarily  the  result  of  our  significant  capital  expenditure  program  during  this  year.  The 
Corporation’s credit facility is $525 million, comprised of a $20 million extendible revolving operating loan facility and a $505 million 
extendible revolving loan facility (the “Credit Facilities”). The Credit Facilities are collateralized by a $1 billion floating charge demand 
debenture  covering  all  assets  of  the  Corporation.  As  well,  the  borrowing  base  for  the  Corporation’s  credit  facilities  is  determined 
through utilizing our regular reserve estimates. The banking syndicate thoroughly evaluates the reserve estimates based upon their own 
commodity  price  expectations  to  determine  the  amount  of  the  borrowing  base.  Revisions  or  changes  in  the  reserve  estimates  and 

Advantage Oil & Gas Ltd. - 23 

 
 
commodity prices can have either a positive or a negative impact on the borrowing base of the Corporation. The next annual review is 
scheduled  to  occur  in  June  2011.  There  can  be  no  assurance  that  the  $525  million  credit  facility  will  be  renewed  at  the  current 
borrowing base level at that time. 

Advantage had a working capital deficiency of $64.5 million as at December 31, 2010. Our working capital includes items expected for 
normal operations such as trade receivables, prepaids, deposits, trade payables and accruals as well as the current portion of capital 
lease obligations. Working capital varies primarily due to the timing of such items, the current level of business activity including our 
capital expenditure program, commodity price volatility, and seasonal fluctuations. Our working capital deficiency is usually higher at 
the  end  of  the  year,  as  would  be  expected,  due  to  accounts  payable  and  accrued  liabilities  associated  with  our  capital  expenditure 
program.  We  do  not  anticipate  any  problems  in  meeting  future  obligations  as  they  become  due  given  the  level  of  our  funds  from 
operations. It is also important to note that working capital is effectively integrated with Advantage’s revolving operating loan facility, 
which  assists  with  the  timing  of  cash  flows  as  required.  Advantage  has  a  capital  lease  obligation  on  various  equipment  used  in  its 
operations. The total amount of principal obligation outstanding at December 31, 2010 is $0.8 million, bearing interest at an effective 
rate of 5.8%, and is collateralized by the related equipment. The lease expires in 2011 at which time title of the equipment will transfer 
to Advantage.

Advantage’s  exploitation  and  development  program  is  focused  primarily  at  Glacier,  Alberta  where  we  are  developing  a  significant 
natural gas resource play. Our preference is to operate a high percentage of our properties such that we can maintain control of capital 
expenditures, operations and cash flows. Advantage’s acquisition strategy has been to acquire long-life properties with strong drilling 
opportunities while retaining a balance of year round access and risk. 

For the year ended December 31, 2010, the Corporation spent a net $153.6 million and drilled a total of 50.2 net (63 gross) wells at a 
98% success rate. Total capital spending included $192.4 million at Glacier, $5.3 million at Sunset, $3.9 million at Nevis, $4.5 million in 
Saskatchewan, and the remaining balance at other areas. However, we continue to focus on development of our Montney natural gas 
resource play at Glacier where Advantage will continue to employ a phased development approach. Phase II was completed during the 
second quarter of 2010 and costs incurred were lower than anticipated due to our successful drilling program which demonstrated well 
productivities  that  exceeded  internal  expectations  and  reduced  drilling  and  completion  costs.  Construction  of  our  facilities  and  gas 
gathering system expansions were completed ahead of schedule and on-budget leading to an earlier than anticipated commissioning of 
Advantage’s  100%  working  interest  gas  plant  in  March  2010.  The  Glacier  gas  plant  has  been  operating  at  its  design  capacity  with 
throughput  rates  between  50  and  55  mmcf/d.  Due  to  stronger  than  expected  well  performance,  we  were  able  to  further  increase 
Glacier production ending the year exceeding 60 mmcf/d (10,000 boe/d). Our Phase III expansion began at the end of the second 
quarter of 2010 and included the drilling of 28 net (28 gross) horizontal wells and the fabrication of a new processing train to facilitate 
expansion of our Glacier gas plant to its current production capacity of 100 mmcf/d. In addition to the current production rate of 100 
mmcf/d, we currently have an incremental 100 mmcf/d (16,667 boe/d) of production capacity available and additional wells will be 
brought on-stream as required to offset declines and maintain production. The amount of excess field production capacity above our 
current plant capacity is a result of our successful drilling program which demonstrated well test rates that exceeded expectations and 
proved up a large portion of our undrilled acreage at Glacier.  

On May 31 and June 3, 2010, we closed two additional asset dispositions of non-core natural gas weighted properties for net proceeds 
of  $66.5  million  and  representing  production  of  approximately  1,700  boe/d.  During  2010  we  had  a  number  of  other  minor 
dispositions that were successfully completed. The net proceeds from the dispositions were utilized to reduce outstanding debt.

Funds from operations decreased during the year ended December 31, 2010 compared to 2009, due to reduced production attributed 
to asset dispositions and lower realized derivative gains from less natural gas production hedged for this year at lower average prices. 
However, funds from operations were positively impacted during 2010 from an improvement in crude oil prices and continued cost 
reduction efforts. Significant asset dispositions were completed in both 2010 and 2009 with proceeds utilized to generally repay bank 
indebtedness and convertible debenture maturities. During the second quarter of 2010 our 6.50% convertible debentures matured and 
were  settled  with  $69.9  million  in  cash.  Bank  indebtedness  increased  in  2010  as  would  be  expected  due  to  our  very  active  capital 
expenditure program that included finalizing our Glacier Phase II program and commencing Phase III that comprised expanding the

fixed assets to maintain a strong balance sheet and preserve financial flexibility.

(1) Long term financial liabilities exclude asset retirement obligations and future income taxes.
(2) On March 18, 2009 Advantage annouced the discontinuance of distributions.

Total  revenue  (before  royalties)  was  significantly  higher  in  2008  as  compared  to  2009  and  2010  due  to  much  stronger  commodity 
prices  and  higher  production.  However,  a  net  loss  was  still  experienced  in  2008  as  we  recognized  a  $120.3  million  impairment  of 
goodwill. For 2009 and 2010,  total revenue (before royalties) decreased significantly as a result of considerably reduced commodity 
prices  and  lower  production  resulting  from  various  asset  dispositions  completed  in  these  years.  The  lower  commodity  prices  also 
primarily contributed to the net losses recognized. Total assets have continually decreased from 2008 through 2010 due to the asset 
dispositions and depletion, depreciation and accretion expense that has exceeded capital spending activity. From 2008 to 2010 we have 
also experienced significant decreases in long term financial liabilities due to our concerted efforts to reduce debt, including utilizing 
net  proceeds  from  significant  asset  dispositions,  an  equity  financing,  and  a  convertible  debenture  issuance.  We  also  suspended  all 
distributions in March 2009 and completed our conversion to a corporation in July 2009.

The table above highlights the Corporation’s and Fund’s performance for the fourth quarter of 2010 and also for the preceding seven 
quarters. Production decreased modestly in the first quarter of 2009 as we experienced freezing conditions from early cold weather. 
Production  increased  in  the  second  quarter of  2009  due  to  recovery from  these cold  weather  conditions  and additional  production 
from a number of wells drilled during the first quarter of 2009 but delayed until after March 31, 2009 such that we could benefit from 
the 5% Alberta Provincial royalty rate available on such wells. We experienced a significant decrease in production during the third

quarter of 2009 as we completed asset dispositions that closed in July 2009. The disposed properties represented approximately 8,100 
boe/d of production. As the third quarter of 2009 still included 1,725 boe/d from the disposed properties, production in the fourth 
quarter of 2009 actually increased 3% from the prior quarter due to a few new wells, partially offset by some natural declines and cold 
weather conditions that typically cause production interruptions. An extended third party facility outage at our Lookout Butte property 
that began in 2008 resulted in 1,100 boe/d of reduced production that continued through much of 2009 but was completed and our 
production came back on in November 2009. Production for the first quarter of 2010 was comparable to the fourth quarter of 2009 
but increased dramatically during the second quarter of 2010 as our new gas plant was completed and production from Glacier was 
increased to between 50 and 55 mmcf/d. We completed two additional asset dispositions during the end of the second quarter of 2010 
representing  approximately  1,700  boe/d  that  resulted  in  modestly  lower  production.  The  full  impact  of  these  recent  dispositions 
resulted in the decrease in production for the third quarter of 2010 with our production remaining consistent during the fourth quarter 
of  2010.  Our  financial  results,  particularly  revenues  and  funds  from  operations,  have  declined  since  2008,  as  commodity  prices 
decreased in response to the financial crisis that materialized in the fall of 2008 and commodity prices continued on a downward trend 
through to the third quarter of 2009. We experienced improvements in commodity prices during the fourth quarter of 2009 and the 
first quarter of 2010 that increased our revenues and funds from operations; however, natural gas prices still remained low. During the 
remainder 2010, natural gas prices weakened again, which has decreased our corresponding revenues and funds from operations. Weak 
commodity prices, particularly natural gas, have generally resulted in the recognized net losses for 2009 through 2010. Advantage did 
report  net  income  in  the  first  quarter  of  2009  as  we  recognized  both  significant  realized  and  unrealized  gains  on  our  derivative 
contracts and moderately lower expenses, including operating costs. Natural gas prices worsen during the second and third quarters of 
2009 resulting in the recognition of net losses for the periods. The third quarter 2009 net loss was also impacted by additional costs 
incurred  related  to  the  corporate  conversion,  including  a  $23.0  million  future  income  tax  expense,  and  increased  depletion  and 
depreciation expense from a higher DD&A rate per boe that resulted from the asset dispositions. The net loss decreased during the 
fourth quarter of 2009 as commodity prices marginally improved. Partially offsetting the net losses experienced during 2009 has been 
the continuing reduction in costs including royalties and operating costs. We recognized net income during the first quarter of 2010 
with improved crude oil prices and realized and unrealized gains on our derivative contracts associated with weak natural gas prices. 
Natural gas prices worsened during the remainder of 2010, resulting in the continued net losses during these quarters. 

Critical Accounting Estimates 

The  preparation  of  financial  statements  in  accordance  with  GAAP  requires  Management  to  make  certain  judgments  and  estimates. 
Changes in these judgments and estimates could have a material impact on the Corporation’s financial results and financial condition. 

Management relies on the estimate of reserves as prepared by the Corporation’s independent qualified reserves evaluator. The process 
of estimating reserves is critical to several accounting estimates. The process of estimating reserves is complex and requires significant 
judgments  and  decisions  based  on  available  geological,  geophysical,  engineering  and  economic  data.  These  estimates  may  change 
substantially  as  additional  data  from  ongoing  development and  production  activities becomes  available  and  as  economic  conditions 
impact  crude  oil  and  natural  gas  prices,  operating  costs,  royalty  burden  changes,  and  future  development  costs.  Reserve  estimates 
impact net income through depletion and depreciation and impairment of petroleum and natural gas properties. The reserve estimates 
are also used to assess the borrowing base for the Corporation’s credit facilities. Revision or changes in the reserve estimates can have 
either a positive or a negative impact on net income and the borrowing base of the Corporation. 

Management’s process of determining the provision for future income taxes, the provision for asset retirement obligation costs and 
related accretion expense, the fair values initially assigned to the convertible debentures liability and equity components, and the fair 
values assigned to any acquired company’s assets and liabilities in a business combination is based on estimates. These estimates are 
significant  and  can  include  proved  and  probable  reserves,  future  production  rates,  future  petroleum  and  natural  gas  prices,  future 
costs, future interest rates, future tax rates and other relevant assumptions. Revisions or changes in any of these estimates can have 
either a positive or a negative impact on asset and liability values and net income. 

In accordance with GAAP, derivative assets and liabilities are recorded at their fair values at the reporting date, with unrealized gains 
and losses recognized directly into net income and comprehensive income in the same period. The fair value of derivatives outstanding 
is an estimate based on pricing models, estimates, assumptions and market data available at that time. As such, the recognized amounts 
are  non-cash  items  and  the  actual  gains  or  losses  realized  on  eventual  cash  settlement  can  vary  materially  due  to  subsequent 
fluctuations in commodity prices and foreign exchange rates as compared to the valuation assumptions.

International Financial Reporting Standards 

In  February  2008,  the  Canadian  Institute  of  Chartered  Accountants  (“CICA”)  confirmed  that  Canadian  GAAP  for  publicly 
accountable enterprises will be replaced by International Financial Reporting Standards (“IFRS”) for the fiscal years beginning on or 
after January 1, 2011. Accordingly, the conversion from Canadian GAAP to IFRS will be applicable to the Corporation’s reporting for 
the first quarter 2011, for which the current and comparative information will be prepared under IFRS. We expect the transition to 
IFRS will impact accounting, financial reporting, processes, internal controls over financial reporting, taxes, and information systems. 
Management has engaged its key personnel responsible and developed an overall plan to address IFRS implementation. We anticipate 
no impact on the Corporations operations or business strategy from conversion to IFRS.  

Phase  one  of  our  plan  consisted  of  a  high  level  assessment  to  identify  key  areas  of  Canadian  GAAP  versus  IFRS  differences  that 
would most likely impact the Corporation. This assessment was completed in early 2009. 

Phase two commenced in the third quarter of 2009 and involved the detailed assessment, from an accounting, financial reporting and 
business perspective, of the changes that would be caused by the conversion to IFRS. Specific accounting processes and policy review 
included:  property,  plant  and  equipment,  exploration  and  evaluation  costs,  depreciation,  impairment  of  assets,  decommissioning 
liabilities and provisions, deferred income taxes, financial reporting and information systems. The deliverables for this phase include 
specific accounting policies for the above mentioned topics and also includes IFRS transitional choices. This phase is currently still in 
progress  but  is  being  finalized.  The  most  significant  change  identified  for  Advantage,  as  with  many  companies  in  the  oil  and  gas 
industry, will be associated with accounting for property, plant and equipment (“PP&E”). During the early stages of this phase, we had 
concentrated on the accounting for PP&E and have now primarily completed our assessments with key policy choices to be approved 
and finalized. We have now also evaluated most other accounting issues identified whereby differences between Canadian GAAP and 
IFRS exist for Advantage and have completed preliminary assessments and developed draft accounting policies. 

Phase three involves the execution of the work completed in phase two, by making changes to business and accounting processes and 
supporting  information  systems,  as  well  as  the  formal  documentation  of  the  final  approved  accounting  policies  and  procedures 
compliant with IFRS. This phase is progressing well and is expected to be completed in early 2011. Details surrounding the collection 
of comparative financial and other data in 2010 are currently being finalized in this phase. We are also in the process of finalizing our 
accounting policies and determining the financial impacts. We have completed our initial draft IFRS transitional balance sheet as of 
January  1,  2010  and  our  first  three  quarters  of  2010  financial  statements  based  on  preliminary  selected  accounting  policies.  Our 
external auditors have been conducting their audit work of our transitional balance sheet and review of our first and second quarters 
of  2010  financial  statements.  Their  work  is  not  yet  completed  and  we  will  have  ongoing  discussions  with  them  through  the  entire 
process. We have now started to prepare draft IFRS financial statements for the fourth quarter of 2010 and believe we are on schedule 
to  complete  the  conversion  within  the  required  deadline.  The  draft  transitional  balance  sheet  and  quarterly  financial  statements  are 
subject to change depending upon the finalization and approval of accounting policies. 

Education and training of key financial employees has been primarily completed. Training of other staff, management, and the Board 
is ongoing throughout the conversion project. Advantage views education and training as critical to our financial reporting controls 
and is a permanent process that we will continue. We will begin an education program for key stakeholders upon finalizing the impacts 
of the IFRS conversion project. 

The  Corporation  has  identified  the  following  areas  as  having  the  greatest  potential  impact  on  the  accounting  policies,  financial 
reporting  and  information  systems  requirements  upon  conversion  to  IFRS.  Differences  between  IFRS  and  Canadian  GAAP  in 
addition  to  those  referred  to  below,  may  still  be  identified  based  on  further  detailed  analysis  and  other  changes  in  IFRS  prior  to 
conversion  in  2011.  Advantage  has  not  yet  finalized  all  of  its  accounting  policies  or  transitional  choices  and  as  such  is  unable  to 
quantify  all  of the  impacts  on  the  financial statements  of  adopting  IFRS  at  this  time.  Any  accounting  policy  selections  or  potential 
impacts  referred  to  below  are  preliminary  and  are  not  finalized  until  all  policies  have  been  selected,  approved  by  the  Board  of 
Directors,  and  completion  of  the  corresponding  audit  and  reviews  by  our  external  auditors.  We  continue  to  monitor  other  IFRS 
developments that may impact our choice of accounting policies. 

a)  Property, plant and equipment 

The Corporation, like many Canadian oil and gas reporting issuers, applies the “full cost” concept in accounting for its oil and gas 
assets. Under full cost, capital expenditures are maintained in a single cost centre for each country, and the cost centre is subject to a 
single depletion and depreciation calculation and impairment test. IFRS will require the Corporation to make a much more detailed 
assessment of its oil and gas assets that will impact depreciation and impairment calculations. Included in this assessment is an ongoing 
appraisal of exploration and evaluation expenditures (“E&E”). Under Canadian GAAP, it is necessary to track costs associated with 
unproved  properties  that  would  be  excluded  from  depletion  and  depreciation  calculations.  Under  IFRS,  a  company  may  choose  to 
expense E&E associated costs or capitalize such costs without recording depreciation expense until the expenditures are determined to 

Advantage Oil & Gas Ltd. - 28 

 
 
represent  technically  feasible  and  commercially  viable  projects  at  which  time  the  costs  are  moved  to  development  properties. 
Advantage currently anticipates that it will select to capitalize E&E costs except for costs incurred before the acquisition of rights to 
explore,  and  to  begin  depreciating  when  technically  feasible  and  commercially  viable.  We  do  not  anticipate  this  to  have  a  material 
impact on our financial results other than to the extent that expenditures may be incurred related to unsuccessful wells or projects that 
will be expensed in the period incurred. 

b)  Depreciation 

For Canadian GAAP purposes, the full cost method of accounting for oil and gas properties requires a single calculation of depletion 
and  depreciation  of  the  carrying  value  of  PP&E  based  on  proved  reserves.  However,  IFRS  requires  an  allocation  of  the  amount 
recognized  as  PP&E  to  each  significant  identified  component  and  each  component  depreciated  separately,  utilizing  an  appropriate 
method  of  depreciation.  This  component  depreciation  of  PP&E  will  result  in  an  increased  number  of  calculations  of  depreciation 
expense  and  may  impact  the  amount  of  depreciation  expense  recognized.  IFRS  also  permits  the  option  of  using  either  proved  or 
proved and probable reserves in the depreciation calculation. Advantage has tentatively concluded at this time to utilize proved and 
probable reserves which we would expect to decrease annual depreciation expense between $90 and $110 million. 

c) 

Impairment of Assets 

Under Canadian GAAP, impairment calculations are prepared according to a two-step test generally conducted at a country level. Step 
one involves a comparison of the PP&E carrying value to the undiscounted net cash flows of proved reserves. If a company should 
fail  step  one,  step  two  is  completed  to  measure  the  amount  of  impairment  whereby  the  PP&E  carrying  value  is  compared  to  a 
calculated  fair  value  with  any  excess  carrying  value  above  the  fair  value  recognized  as  an  impairment  loss.  Impairment  losses 
recognized under Canadian GAAP are not subsequently reversed. Under IFRS, impairment testing is completed at an individual asset 
group or “Cash Generating Unit” level (“CGU”) when indicators suggest there may be impairment. A CGU is defined as the smallest 
group of assets that produce independent cash flows. Impairment of assets at a CGU level use a one-step approach for testing and 
measuring asset impairment, with asset carrying values compared to the higher of “Value in Use” and “Fair Value less Costs to Sell”. 
The IFRS methodology may result in the possibility of more frequent impairments in the carrying value of PP&E. However, under 
IFRS  previous  impairment  losses  (except  for  goodwill)  must  be  reversed  where  circumstances  change  such  that  the  previously 
recognized impairment has been reduced. Advantage has completed an initial assessment of CGU’s as of the transition date and has 
determined there to be 12 CGU’s. The number of CGU’s is subject to change as Advantage’s portfolio of assets may change through 
development activities, acquisitions or dispositions. 

d)  Decommissioning Liabilities 

Both Canadian GAAP and IFRS require a company to provide for a liability related to decommissioning PP&E. Both methodologies 
are similar and we have determined there to be no significant difference for Advantage, other than a potential difference related to 
discount rates. Canadian GAAP requires that the decommissioning liability be discounted at a credit-adjusted risk-free rate while IFRS 
requires that the decommissioning liability be discounted at an appropriate rate with either the cash flows or rate adjusted for risks. As 
a result, there currently is the possibility of using a risk-free rate or a credit-adjusted risk-free rate. Advantage has tentatively selected to 
use the risk-free rate for discounting purposes, currently determined to be approximately 4%, and we expect this would increase the 
decommissioning liability at transition date between $100 and $110 million. 

e)  Deferred Income Taxes 

Future income taxes under Canadian GAAP and deferred income taxes under IFRS are similar for Advantage and we are continuing 
to evaluate this complex area. However, any differences in decommissioning liabilities and PP&E, including depreciation, will impact 
the carrying value as reported on the balance sheet and therefore result in a difference in the balance of deferred taxes reported under 
IFRS. 

f)  First Time Adoption of International Financial Reporting Standards 

IFRS 1 provides the framework for the first time adoption of IFRS and specifies that an entity shall apply the principles under IFRS 
retrospectively. IFRS 1 also specifies that the adjustments that arise on retrospective conversion to IFRS from other GAAP should be 
directly  recognized  in  retained  earnings.  Certain  optional  exemptions  and  mandatory  exceptions  to  retrospective  application  are 
provided under IFRS 1. Advantage has chosen to apply an exemption that allows an entity that used full cost accounting, at adoption 
of IFRS, to measure exploration and evaluation assets at the amount measured under its previous GAAP for those assets. The entity 
may  also measure  its  oil  and gas assets  in  the development  and  production  phases,  by allocating  the  amount determined  under the 
entities previous GAAP to the underlying assets and areas pro rata using reserve volumes or reserve values as of that date. Advantage 
has made a preliminary allocation based on proved and probable reserves values discounted at 10%. The allocation process had no 
impact on Advantage’s carrying value of PP&E. As a result of applying this exemption, Advantage will also be required to complete an 

Advantage Oil & Gas Ltd. - 29 

 
 
impairment test under IFRS on the transition date. A preliminary impairment test has been completed for the tentatively determined 
CGU’s and there is currently no impairment at transition date. 

Advantage has also elected not to reevaluate prior completed business combinations under Canadian GAAP and has simply reviewed 
such prior business combinations accounting to ensure that no assets were recognized that would be inappropriate under IFRS. We 
have not found any such items and there will be no impact from choosing this exemption. 

g)  Financial Reporting 

The  adoption  of  IFRS  will  result  in  different  presentation  and  additional  disclosure  requirements  in  the  financial  statements.  Draft 
IFRS  financial  statements  including  notes  have  been  prepared  and  are  being  reviewed  with  our  external  auditors  and  Board  of 
Directors. We anticipate that review and discussion of the presentation and disclosures will continue until the first interim financial 
statements are released for the quarter ended March 31, 2011. 

h) 

Information Systems 

The adoption of IFRS will have an impact on information systems requirements. We have evaluated our financial reporting systems 
and  have  made  current  changes  to  accommodate  IFRS.  We  will  continue  assessing  the  need  for  additional  system  upgrades  or 
modifications to ensure an efficient conversion to IFRS and to improve ongoing processes. 

i) 

Internal Controls 

In accordance with the Corporations approach to certification of internal controls required under Canadian Securities Administrators’ 
National instrument 52-109 and SOX 302 and 404, all entity level, information technology, disclosures and business process controls 
will require updating and testing to reflect changes arising from our conversion to IFRS. Upon review with internal audit, we have 
determined there to be minimal updating of processes, controls and documentation required. We will work on updating our processes, 
controls and documentation during the final phase of IFRS conversion. 

Controls and Procedures 

The Corporation has established procedures and internal control systems to provide reasonable assurance regarding the reliability of 
financial reporting and the preparation of financial statements for external purposes in accordance with GAAP. Management of the 
Corporation  is  committed  to  providing  timely,  accurate  and  balanced  disclosure  of  all  material  information  about  the  Corporation. 
Disclosure  controls  and  procedures  are  in  place  to  ensure  all  ongoing  reporting  requirements  are  met  and  material  information  is 
disclosed on a timely basis. The Chief Executive Officer and President and Chief Financial Officer, individually, sign certifications that 
the  financial  statements,  together  with  the  other  financial  information  included  in  the  regular  filings,  fairly  present  in  all  material 
respects the financial condition, results of operations, and cash flows as of the dates and for the periods presented in the filings. The 
certifications further acknowledge that the filings do not contain any untrue statement of a material fact or omit to state a material fact 
required to be stated or that is necessary to make a statement not misleading in light of the circumstances under which it was made, 
with respect to the period covered by the filings. 

Evaluation of Disclosure Controls and Procedures 

The Corporation has established a Disclosure Committee consisting of the executive members with the responsibility of overseeing 
the Corporation’s disclosure practices and designing disclosure controls and procedures, as specified under Canadian and US securities 
law, to provide reasonable assurance that information required to be disclosed by the Corporation in its annual filings, interim filings 
or other reports filed or submitted by the Corporation under applicable securities legislation is recorded, processed, summarized and 
reported  within  the  time  periods  specified  in  applicable  securities  legislation  and  that  all  material  information  relating  to  the 
Corporation is made known to them by others, particularly during the period in which the Corporation’s annual and interim filings are 
being prepared. All written public disclosures are reviewed and approved by at least one member of the Disclosure Committee prior to 
issuance. Additionally, the Disclosure Committee assists the Chief Executive Officer and President and Chief Financial Officer of the 
Corporation in making certifications with respect to the disclosure controls of the Corporation required under applicable regulations 
and ensures that the Board of Directors is promptly and fully informed regarding potential disclosure issues facing the Corporation.  

Management  of  Advantage,  including  our  Chief  Executive  Officer  and  President  and  Chief  Financial  Officer,  has  evaluated  the 
effectiveness  of  the  design  and  operation  of  the  disclosure  controls  and  procedures  as  of  December  31,  2010.  Based  on  that 
evaluation,  our  Chief  Executive  Officer  and  President  and  Chief  Financial  Officer  have  concluded  that  the  disclosure  controls  and 
procedures are effective as of the end of the period, in all material respects. It should be noted that while the Chief Executive Officer 
and  President  and  Chief  Financial  Officer  believe  that  the  Corporation’s  design  of  disclosure  controls  and  procedures  provide  a 
reasonable level of assurance that they are effective, they do not expect that the disclosure controls and procedures or internal control 

Advantage Oil & Gas Ltd. - 30 

 
 
over financial reporting will prevent all errors and fraud. A control system does not provide absolute, but rather is designed to provide 
reasonable assurance that the objective of the control system is met. 

Management’s Report on Internal Controls over Financial Reporting 

The Corporation’s Management is responsible for establishing and maintaining adequate internal control over financial reporting as 
such  term  is  defined  in  the  rules  of  the  United  States  Securities  and  Exchange  Commission  and  the  Canadian  Securities 
Administrators. The Corporation’s internal control over financial reporting is a process designed, under the supervision and with the 
participation  of  executive  and  financial  officers  of  the  Corporation,  to  provide  reasonable  assurance  regarding  the  reliability  of 
financial reporting and the preparation of the Corporation’s financial statements for external reporting purposes in accordance with 
GAAP. 

The  Corporation’s  internal  control  over  financial  reporting  includes  policies  and  procedures  that:  (i)  pertain  to  the  maintenance  of 
records that, in reasonable detail, accurately and fairly reflect transactions and dispositions of assets of the Corporation; (ii) provide 
reasonable  assurance  that  transactions  are  recorded  as  necessary  to  permit  preparation  of  financial  statements  in  accordance  with 
GAAP; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition 
of the Corporation’s assets that could have a material effect on the financial statements. 

The Corporation’s internal control over financial reporting may not prevent or detect all misstatements because of inherent limitations. 
Additionally,  projections  of  any  evaluation  of  effectiveness  to  future  periods  are  subject  to  the  risk  that  controls  may  become 
inadequate  because  of  changes  in  conditions  or  deterioration  in  the  degree  of  compliance  with  the  Corporation’s  policies  and 
procedures. 

The Corporation’s management assessed the design and effectiveness of the internal control over financial reporting as of December 
31,  2010,  based  on  the  framework  established  in  Internal  Control  –  Integrated  Framework  issued  by  the  Committee  of  Sponsoring 
Organizations of the Treadway Commission. Based on this assessment, the Chief Executive Officer and President and Chief Financial 
Officer concluded that the Corporation maintained effective internal control over financial reporting as of December 31, 2010. 

During the year ended December 31, 2010, there has been no change in the Corporation’s internal control over financial reporting that 
has materially affected, or is reasonably likely to materially affect, the Corporation’s internal control over financial reporting. 

Corporate Governance 

The  Board  of  Directors’  mandate  is  to  supervise  the  management  of  the  business  and  affairs  of  the  Corporation.  In  particular,  all 
decisions relating to: (i) the acquisition and disposition of properties for a purchase price or proceeds in excess of $5 million; (ii) the 
approval  of  annual  operating  and  capital  expenditure  budgets;  and  (iii)  the  establishment  of  credit  facilities  and  the  issuance  of 
additional shares, will be made by the Board. 
The Board  of Directors  meets  regularly  to  review  the  business  and  affairs  of  the  Corporation  to make  any  required decisions.  The 
Board of Directors consists of nine members, seven of whom are unrelated to the Corporation. The Independent Reserve Evaluation 
Committee  has  four  members,  the  Audit  Committee  has  four  members,  and  the  Human  Resources,  Compensation  and  Corporate 
Governance  Committee  has  three  members.  All  members  of  the  various  committees  are  independent.  One  member  of  the  Audit 
Committee has been designated a “Financial Expert” as defined in applicable regulatory guidance. In addition, the Chairman of the 
Board is not related and is not an executive officer of the Corporation. 
The Board of Directors approved and Management implemented a Code of Business Conduct and Ethics. The purpose of the code is 
to lay out the expectation for the highest standards of professional and ethical conduct from our directors, officers and employees. 
The code reflects our commitment to a culture of honesty, integrity and accountability and outlines the basic principles and policies 
with  which  all  employees  are  expected  to  comply.  Our  Code  of  Business  Conduct  and  Ethics  is  available  on  our  website  at 
www.advantageog.com. 
As a foreign private issuer listed on the New York Stock Exchange (the "NYSE"), Advantage is not required to comply with most of 
the NYSE rules and listing standards and instead may comply with domestic Canadian requirements. Advantage is, however, required 
to comply with the following NYSE Rules: (i) Advantage must have an audit committee that satisfies the requirements of Rule 10A-3 
under  the  United  States  Securities  Exchange  Act  of  1934,  as  amended;  (ii)  the  Chief  Executive  Officer  must  promptly  notify  the 
NYSE  in  writing  after  an  executive  officer  becomes  aware  of  any  material  non-compliance  with  the  applicable  NYSE  Rules;  (iii) 
submit an executed annual written affirmation to the NYSE, as well as an interim affirmation each time certain changes occurs to the 
audit  committee;  and  (iv)  provide  a  brief  description  of  any  significant  differences  between  its  corporate  governance  practices  and 
those followed by U.S. domestic issuers listed under the NYSE. Advantage has reviewed the NYSE listing standards and confirms that 
its corporate governance practices do not differ significantly from such standards. 
A further discussion of the Corporation’s corporate governance practices can be found in the Management Proxy Circular.

Creation of Longview Oil Corp. 

On March 7, 2011 Advantage announced that Longview Oil Corp. (“Longview”), a wholly-owned subsidiary of the Corporation, filed 
a preliminary prospectus on March 4, 2011 for an initial public offering (the “Offering”), which is targeted to raise gross proceeds of 
$150 million prior to an over-allotment option of up to 15% of the base offering size, exercisable 30 days following the closing of the 
Offering. The closing of the Offering is expected to occur in April, 2011. 

Longview  was  created  to  acquire  certain  oil-weighted  assets  (the  “Acquired  Assets”)  located  in  West  Central  Alberta,  Southeast 
Saskatchewan and the Lloydminster area of Saskatchewan with fourth quarter 2010 average production of 6,220 boe/d (74% crude oil 
and NGLs, proved reserves of 20.1 mmboe and proved plus probable reserves of 36.9 mmboe, based on a report prepared by Sproule 
& Associates Limited on the Acquired Assets for Advantage and Longview with an effective date of December 31, 2010. Longview’s 
business strategy is to provide shareholders with attractive long-term returns that combine both growth and yield by exploiting the 
Acquired Assets in a financially disciplined manner, acquiring additional long-life oil and gas assets of a similar nature and through the 
payment of a monthly dividend. 

Concurrent  with  closing  of  the  Offering,  Longview  will  purchase  the  Acquired  Assets  from  Advantage  (the  “Transaction”),  with 
consideration comprised of the net proceeds of the Offering, common shares of Longview and proceeds of $100 million to be drawn 
from an independent Longview credit facility (which is anticipated to be $200 million) to be established at closing. Advantage plans to 
use the cash proceeds from the Transaction to reduce outstanding bank indebtedness. The Transaction is conditional upon customary 
industry conditions including the approval of the Board of Directors of Advantage. 

Advantage will retain an equity ownership interest of approximately 67% of the common shares of Longview (approximately 62% if 
the over-allotment option is exercised in full). Concurrent with closing of the Offering, Advantage will enter into a Technical Services 
Agreement  (the  “TSA”)  with  Longview.  Under  the  TSA,  Advantage  will  provide  the  necessary  personnel  and  technical  services  to 
manage Longview's business and Longview will reimburse Advantage on a monthly basis for its share of administrative charges based 
on respective levels of production. Longview will have an independent board of directors with three initial members. The officers of 
Longview will provide services to Longview under the TSA but will remain as employees of Advantage. 

As  a  result  of  the  successful  completion  of  the  Transaction,  historical  financial  and  operating  performance  as  well  as 
forward-looking information may not be indicative of actual future performance. 

Outlook 

During  the  first  half  of  2010,  we  successfully  completed  our  Phase  II  Montney  development  program  at  Glacier  which  involved 
drilling  horizontal  wells  to  build  production  inventory  and  delineate  our  land  block.  Construction  on  Advantage’s  100%  working 
interest  gas  plant  and  gathering  system  expansion  was  completed  ahead  of  schedule  and  on-budget  leading  to  an  earlier  than 
anticipated commissioning during March 2010. The Glacier gas plant has since been operating at its design capacity with throughput 
rates  between  50  and  55  mmcf/d.  Due  to  stronger  than  expected  well  performance,  we  were  able  to  further  increase  Glacier 
production ending the year exceeding 60 mmcf/d (10,000 boe/d). 

Phase III of our Glacier development project began at the end of the second quarter of 2010 and included the drilling of 28 net (28 
gross) horizontal wells and the fabrication of a new processing train to facilitate expansion of our Glacier gas plant to a production 
capacity of 100 mmcf/d. At this time, in addition to the 100 mmcf/d of current production, we have an incremental 100 mmcf/d 
(16,667  boe/d)  of  production  capacity  available  and  additional  wells  will  be  brought  on-stream  as  required  to  offset  declines  and 
maintain  production.  The  amount  of  excess  field  production  capacity  above  our  current  plant  capacity  is  a  result  of  our  successful 
drilling program which demonstrated well test rates that exceeded expectations and proved up a large portion of our undrilled acreage 
at Glacier. 

Drilling results at our cornerstone Glacier property have demonstrated that our Montney development is among the top tier natural 
gas  resource  developments  in  North  America.  The  attractive  cost  structure  at  Glacier  which  includes  low  operating  costs  and  low 
royalty rates combined with a multi-decade drilling inventory provides a strong foundation to drive future development beyond 100 
mmcf/d of production. With the expansion of Glacier to 100 mmcf/d now completed, a review of well performance, facility capacity 
and actual costs will be undertaken by Advantage to assess the timing and capital requirements for the next phase of growth at Glacier. 
Advantage will provide additional corporate guidance and communicate future development plans on or about mid-year 2011.

Independent Auditor’s Report 

To the Shareholders

111 5 Avenue SW, Suite 3100

We have completed integrated audits of Advantage Oil & Gas Ltd.’s 2010 and 2009 
consolidated financial statements and its internal control over financial reporting as at December 31, 2010. Our 
opinions, based on our audits, are presented below.  

Report on the consolidated financial statements  

We have audited the accompanying consolidated financial statements of Advantage Oil & Gas Ltd., which 
comprise the consolidated balance sheets as at December 31, 2010 and 2009 and the consolidated statements of 
loss, comprehensive loss and deficit and cash flows for the years then ended, and the related notes including a 
summary of significant accounting policies. 

Management’s responsibility for the consolidated financial statements 
Management is responsible for the preparation and fair presentation of these consolidated financial statements in 
accordance with Canadian generally accepted accounting principles and for such internal control as management 
determines is necessary to enable the preparation of consolidated financial statements that are free from material 
misstatement, whether due to fraud or error. 

Auditor’s responsibility 
Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We 
conducted our audits in accordance with Canadian generally accepted auditing standards and the standards of the 
Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform 
an audit to obtain reasonable assurance about whether the consolidated financial statements are free from 
material misstatement. Canadian generally accepted auditing standards require that we comply with ethical 
requirements.  

An audit involves performing procedures to obtain audit evidence, on a test basis, about the amounts and 
disclosures in the consolidated financial statements. The procedures selected depend on the auditor’s judgment, 
including the assessment of the risks of material misstatement of the consolidated financial statements, whether 
due to fraud or error. In making those risk assessments, the auditor considers internal control relevant to the 
company’s preparation and fair presentation of the consolidated financial statements in order to design audit 
procedures that are appropriate in the circumstances. An audit also includes evaluating the appropriateness of 
accounting principles and policies used and the reasonableness of accounting estimates made by management, 
as well as evaluating the overall presentation of the consolidated financial statements. 

We believe that the audit evidence we have obtained in our audits is sufficient and appropriate to provide a basis 
for our audit opinion on the consolidated financial statements. 

Opinion 
In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of 
Advantage Oil & Gas Ltd. as at December 31, 2010 and 2009 and the results of its operations and cash flows for 
the years then ended in accordance with Canadian generally accepted accounting principles.

All tabular amounts in thousands except as otherwise indicated. 

1. 

Business and Structure of Advantage Oil & Gas Ltd. 

Advantage Oil & Gas Ltd. (“Advantage” or the “Corporation”) is an intermediate oil and natural gas exploration and production 
corporation with properties located in Western Canada.  Advantage was created on July 9, 2009, through the completion of a plan 
of  arrangement  pursuant  to  an  information  circular  dated  June  5,  2009.  Advantage  Energy  Income  Fund  (the  “Fund”)  was 
dissolved and converted into the corporation, Advantage Oil and Gas Ltd., with each Trust Unit converted into one Common 
Share.  

2. 

Summary of Significant Accounting Policies 

The  Management  of  the  Corporation  prepares  its  consolidated  financial  statements  in  accordance  with  Canadian  generally 
accepted  accounting  principles  (“Canadian  GAAP”)  and  all  amounts  are  stated  in  Canadian  dollars.  The  preparation  of 
consolidated  financial  statements  requires  Management  to  make  estimates  and  assumptions  that  affect  the  reported  amount  of 
assets, liabilities and equity and disclosures of contingencies at the date of the consolidated financial statements and the reported 
amounts of revenues and expenses during the periods. The following significant accounting policies are presented to assist the 
reader in evaluating these consolidated financial statements and, together with the notes, should be considered an integral part of 
the consolidated financial statements.  

(a) Consolidation and joint operations 

These consolidated financial statements include the accounts of the Corporation and all subsidiaries. All intercompany balances 
and transactions have been eliminated. 

The Corporation conducts exploration and production activities jointly with other participants. The accounts of the Corporation 
reflect its proportionate interest in such joint operations. 

(b) Fixed assets 

(i) Petroleum and natural gas properties 

The  Corporation  follows  the  “full  cost”  method  of  accounting  in  accordance  with  the  guideline  issued  by  the  Canadian 
Institute of Chartered Accountants (“CICA”) whereby all costs associated with the acquisition of and the exploration for and 
development of petroleum and natural gas reserves, whether productive or unproductive, are capitalized in a Canadian cost 
centre  and  charged  to  income  as  set  out  below.  Such  costs  include  lease  acquisition,  drilling  and  completion,  production 
facilities,  asset  retirement  costs,  geological  and  geophysical  costs  and  overhead  expenses  related  to  exploration  and 
development activities, net of any government incentive programs.  

Gains  or  losses  are  not  recognized  upon  disposition  of  petroleum  and  natural  gas  properties  unless  crediting  the  proceeds 
against accumulated costs would result in a change in the rate of depletion and depreciation of 20% or more. 

Depletion  of  petroleum  and  natural  gas  properties  and  depreciation  of  lease,  well  equipment  and  production  facilities  is 
provided on accumulated costs using the “unit-of-production” method based on estimated proved petroleum and natural gas 
reserves, before royalties, as determined by independent engineers. For purposes of the depletion and depreciation calculation, 
proved petroleum and natural gas reserves are converted to a common unit-of-measure on the basis of one barrel of oil or 
liquids being equal to six thousand cubic feet of natural gas. 

The depletion and depreciation cost base includes total capitalized costs, less costs of unproved properties, plus an estimate of 
future  development  costs  of  proved  undeveloped  reserves.  Costs  of  acquiring  and  evaluating  unproved  properties  are 
excluded from depletion calculations until it is determined whether or not proved reserves are attributable to the properties or 
impairment occurs. 

Petroleum and natural gas properties are evaluated in each reporting period to determine that the carrying amount in a cost 
centre is recoverable and does not exceed the fair value of the properties in the cost centre (the “ceiling test”). The carrying 
amounts are assessed to be recoverable when the sum of the undiscounted net cash flows expected from the production of  

Advantage Oil & Gas Ltd. - 40 

 
 
 
 
(i) Petroleum and natural gas properties (continued) 
proved reserves, the lower of cost and market of unproved properties and the cost of major development projects exceeds the 
carrying  amount  of  the  cost  centre.  When  the  carrying  amount  is  not  assessed  to  be  recoverable,  an  impairment  loss  is 
recognized  to  the  extent  that  the  carrying  amount  of  the  cost  centre  exceeds  the  sum  of  the  discounted  net  cash  flows 
expected from the production of proved and probable reserves, the lower of cost and market of unproved properties and the 
cost of major development projects of the cost centre. The net cash flows are estimated using expected future product prices 
and costs and are discounted using a risk-free interest rate.  

(ii) Furniture and equipment 

The Corporation records furniture and equipment at cost and provides depreciation on the declining balance method at a rate 
of  20%  per  annum  which  is  designed  to  amortize  the  cost  of  the  assets  over  their  estimated  useful  lives.  The  Corporation 
records leasehold improvements at cost and provides depreciation on the straight-line method over the term of the lease. 

(c) Distributions 

Distributions previously declared by the Fund were reported on an accrual basis.  

(d) Financial instruments 

The Corporation’s financial instruments consist of financial assets, financial liabilities, and non-financial derivatives.  All financial 
instruments are initially recognized at fair value on the balance sheet.  Measurement of financial instruments subsequent to the 
initial  recognition,  as  well  as  resulting  gains  and  losses,  is  based  on  how  each  financial  instrument  was  initially  classified.    The 
Corporation  has  classified  each  identified  financial  instrument  into  the  following  categories:  held  for  trading,  loans  and 
receivables, held to maturity investments, available for sale financial assets, and other financial liabilities. Held for trading financial 
instruments are measured at fair value with gains and losses recognized in earnings immediately.  Available for sale financial assets 
are measured at fair value with gains and losses, other than impairment losses, recognized in other comprehensive income and 
transferred to earnings when the asset is derecognized. Loans and receivables, held to maturity investments and other financial 
liabilities  are  recognized  at  amortized  cost  using  the  effective  interest  method  and  impairment  losses  are  recorded  in  earnings 
when incurred. With all new financial instruments, an election is available that allows entities to classify any financial instrument as 
held for trading.  Only those financial assets and liabilities that must be classified as held for trading are classified as such by the 
Corporation. 

Derivative  instruments  executed  by  the  Corporation  to  manage  market  risk  associated  with  volatile  commodity  prices  are 
classified as held for trading and recorded on the balance sheet at fair value as derivative assets and liabilities. Gains and losses on 
these instruments are recorded as unrealized gains and losses on derivatives in the consolidated statement of loss, comprehensive 
loss  and  deficit  in  the  period  they  occur  and  as  realized  gains  and  losses  on  derivatives  when  the  contracts  are  settled.    Since 
unrealized  gains  and  losses  on  derivatives  are  non-cash  items,  there  is  no  impact  on  cash  provided  by  operating  activities  as  a 
result of their recognition.  

Transaction costs are frequently attributed to the acquisition or issue of a financial asset or liability. Such costs incurred on held 
for  trading  financial  instruments  are  expensed  immediately.  For  other  financial  instruments,  an  entity  can  adopt  an  accounting 
policy  of  either  expensing  transaction  costs  as  they  occur  or  adding  such  transaction  costs  to  the  fair  value  of  the  financial 
instrument.  The Corporation has chosen a policy of adding transaction costs to the fair value initially recognized for financial 
assets and liabilities that are not classified as held for trading.  

(e) Comprehensive income 

Comprehensive income consists of net income and other comprehensive income (“OCI”) with amounts included in OCI shown 
net of tax. Accumulated other comprehensive income is comprised of the cumulative amounts of OCI. To date, the Corporation 
does not have any adjustments in OCI and therefore comprehensive loss is currently equal to net loss. 

(f) Convertible debentures 

The Corporation’s convertible debentures are financial liabilities consisting of a liability with an embedded conversion feature. As 
such, the debentures are segregated between liabilities and equity based on the residual value method, where the liability is first 
measured using a discount rate without the conversion feature and the remaining amount is allocated to equity. Therefore, the 
debenture  liabilities  are  presented  at  less  than  their  eventual  maturity  values.  The  liability  and  equity  components  are  further 
reduced for issuance costs initially incurred. The discount of the liability component as compared to maturity value is accreted by 
the  “effective  interest”  method  over  the  debenture  term  and  expensed  accordingly.  As  debentures  are  converted  to  shares,  an 
appropriate portion of the liability and equity components are transferred to share capital.  

Advantage Oil & Gas Ltd. - 41 

 
 
 
 
 (g) Asset retirement obligations 
The Corporation records the future cost associated with removal, site restoration and asset retirement costs. The fair value of the 
liability  for  the  Corporation’s  asset  retirement  obligations  is  recorded  in  the  period  in  which  it  is  incurred,  discounted  to  its 
present  value  using  the  Corporation’s  credit  adjusted  risk-free  interest  rate  and  the  corresponding  amount  recognized  by 
increasing the carrying amount of fixed assets. The asset recorded is depleted on a “unit-of-production” basis over the life of the 
reserves consistent with the Corporation’s depletion and depreciation policy for petroleum and natural gas properties. The liability 
amount is increased each reporting period due to the passage of time and the amount of accretion is charged to income in the 
period.  Revisions  to  the  estimated  timing  of  cash  flows  or  to  the  original  estimated  undiscounted  cost  could  also  result  in  an 
increase or decrease to the obligation. Actual costs incurred upon settlement of the retirement obligations are charged against the 
obligation to the extent of the liability recorded. 

(h) Income taxes 

The  Corporation  follows  the  “liability”  method  of  accounting  for  future  income  taxes.  Under  this  method  future  income  tax 
assets and liabilities are determined based on differences between the carrying value of an asset or liability and its tax basis using 
substantively enacted tax rates and laws expected to apply when the differences reverse. The effect a change in income tax rates 
has on future tax assets and liabilities is recognized in net income in the period in which the change is substantively enacted. 

(i) Equity-based compensation 

Advantage accounts for compensation expense based on the “fair value” of rights granted under its equity-based compensation 
plans.  Prior to converting to a corporation, the Fund had Trust Units held in escrow relating to management internalization (note 
10) and a Restricted Trust Unit Plan.  Subsequent to converting to a corporation, Advantage has a Restricted Share Performance 
Incentive Plan (note 10). 

The  escrowed  Trust  Units  relating  to  the  management  internalization  vested  equally  over  three  years,  the  period  during  which 
employees were required to provide service to receive the Trust Units. Therefore, the management internalization consideration 
was  being deferred  and  amortized  into  income  as  management  internalization expense  over the specific vesting periods during 
which employee services were provided, including an estimate of future Trust Unit forfeitures.  

Advantage’s Restricted Share Performance Incentive Plan (“RSPIP” or the “Plan”), authorizes the Board of Directors to grant 
restricted shares to service providers of the Corporation, including directors, officers, employees, and consultants. The restricted 
share grants generally vest one-third immediately on grant date, with the remaining two-thirds vesting evenly on the following two 
yearly  anniversary  dates.  Compensation  cost  related  to  the  Plan  is  recognized  as  compensation  expense  within  general  and 
administrative expense over the service period and incorporates the share grant price, the estimated number of restricted shares to 
vest,  and  certain  management  estimates.  As  compensation  expense  is  recognized,  contributed  surplus  is  recorded  until  the 
restricted shares vest at which time the appropriate shares are then issued to the services providers and the contributed surplus is 
transferred to share capital.  The Plan replaced the previous Restricted Trust Unit (“RTU”) plan that was in place prior to the 
conversion to a corporation and for which the accounting was the same. 

(j) Revenue recognition  

Revenue associated with the sale of petroleum, natural gas and natural gas liquids is recognized when the title and risks pass to the 
purchaser, normally at the pipeline delivery point for natural gas and at the wellhead for crude oil.  

(k) Per share amounts 

Net loss per share is calculated using the weighted average number of shares outstanding during the year. Diluted net loss per 
share is calculated using the “if-converted” method to determine the dilutive effect of convertible debentures and the “treasury 
stock” method for equity-based compensation. 

(l) Measurement uncertainty 

The  amounts  recorded  for  depletion  and  depreciation  of  fixed  assets,  the  provision  for  asset  retirement  obligation  costs  and 
related accretion expense, impairment calculations for fixed assets, derivative fair value calculations, future income tax provisions, 
fair  values  initially  assigned  to  convertible  debentures  liability  and  equity  components,  as  well  as  fair  values  assigned  to  any 
identifiable  assets  and  liabilities  in  business  combinations  are  based  on  estimates.  These  estimates  are  significant  and  include 
proved and probable reserves, future production rates, future petroleum and natural gas prices, future costs, future interest rates, 
future  tax  rates,  fair  value  assessments,  and  other  relevant  assumptions.  By  their  nature,  these  estimates  are  subject  to 
measurement  uncertainty  and  the  effect  on  the  consolidated  financial  statements  of  changes  in  such  estimates  in  future  years 
could be material.

In  May  and  June  2010,  Advantage  closed  two  asset  dispositions  for  net  cash  proceeds  of  $66.5  million,  and  other  minor 
dispositions of $3.2 million (December 31, 2009 - $245.2 million). As these dispositions did not result in a change of more than 
20% in the rate of depletion and depreciation, no gain or loss was recognized. 

During  the  year  ended  December  31,  2010,  Advantage  capitalized  general  and  administrative  expenditures  directly  related  to 
exploration and development activities of $9.6 million (December 31, 2009 - $10.2 million). 

Costs of $30.7 million (December 31, 2009 - $38.2 million) for unproved properties have been excluded from the calculation of 
depletion expense, and future development costs of $1.2 billion (December 31, 2009 - $845.3 million) have been included in costs 
subject to depletion. 

The Corporation performed a ceiling test calculation at December 31, 2010 to assess the recoverable value of fixed assets. Based 
on  the  calculation,  there  has  been  no  impairment  of  the  Corporation’s  petroleum  and  natural  gas  properties.  The  carrying 
amounts are recoverable as compared to the sum of the undiscounted net cash flows expected from the production of proved 
reserves based on the following benchmark prices:

Convertible Debentures (continued) 

The principal amount of 8.25% convertible debentures matured on February 1, 2009 and were settled by issuing 946,887 Trust 
Units.  The  8.75%  convertible  debentures  matured  and  were  settled  with  $29.8  million  in  cash  on  June  30,  2009.    The  7.50% 
convertible debentures matured and were settled with $52.3 million in cash on September 30, 2009. 

The principal amount of 6.50% convertible debentures matured and were settled with $69.9 million in cash on June 30, 2010. 

On December 31, 2009, 5.00% convertible debentures were issued for net proceeds of $82.5 million.  The debentures have a face 
value of $1,000 per debenture, mature on January 30, 2015 and are convertible into shares of the Corporation at the option of the 
holder at a conversion price of $8.60.  The debentures pay interest semi-annually in arrears on January 31 and July 31 of each year, 
commencing on July 31, 2010. The debentures will not be redeemable by the Corporation prior to January 31, 2013. On and after 
January 31, 2013 and prior to January 30, 2015, the debentures may be redeemed by the Corporation in whole or in part from 
time  to  time  at  the  option  of  the  Corporation  at  a  redemption  price  equal  to  their  principal  amount  plus  accrued  and  unpaid 
interest, provided that the Current Market Price is at least 125% of the Conversion Price. In the event that a holder of debentures 
exercises  their  conversion  right  following  a  notice  of  redemption  by  the  Corporation,  such  holder  shall  be  entitled  to  receive 
accrued and unpaid interest, in addition to the applicable number of shares to be received on conversion. 

During the years ended December 31, 2010 and 2009, there were no convertible debenture conversions.

Advantage’s credit facilities of $525 million is comprised of a $20 million extendible revolving operating loan facility from one 
financial  institution  and  a  $505  million  extendible  revolving  loan  facility  from  a  syndicate  of  financial  institutions  (the  "Credit 
Facilities"). Amounts borrowed under the Credit Facilities bear interest at a floating rate based on the applicable Canadian prime 
rate, US base rate, LIBOR rate or bankers' acceptance rate plus between 1.25% and 3.75% depending on the type of borrowing 
and  the  Corporation’s  debt  to  cash  flow  ratio.  The  Credit  Facilities  are  collateralized  by  a  $1  billion  floating  charge  demand 
debenture  covering  all  assets  of  the  Corporation.  The  amounts  available  to  Advantage  from  time  to  time  under  the  Credit 
Facilities  are  based  upon  the  borrowing  base  determined  semi-annually  by  the  lenders.  The  revolving  period  for  the  Credit 
Facilities will end in June 2011 unless extended at the option of the syndicate for a further 364 day period. If the Credit Facilities 
are not extended, they will convert to non-revolving term facilities due 365 days after the last day of the revolving period. The 
credit facilities prohibit the Corporation from entering into any derivative contract where the term of such contract exceeds three 
years.    Further,  the  aggregate  of  such  contracts  cannot  hedge  greater  than  60%  of  total  estimated  petroleum  and  natural  gas 
production over two years and 50% over the third year. The Credit Facilities contain standard commercial covenants for credit 
facilities of this nature. The only financial covenant is a requirement for Advantage to maintain a minimum cash flow to interest 
expense ratio of 3.5:1, determined on a rolling four-quarter basis. This covenant was met at December 31, 2010 and 2009. Breach 
of any covenant will result in an event of default in which case Advantage has 20 days to remedy such default. If the default is not 
remedied or waived, and if required by the lenders, the administrative agent of the lenders has the option to declare all obligations 
under  the  credit  facilities  to  be  immediately  due  and  payable  without  further  demand,  presentation,  protest,  days  of  grace,  or 
notice of any kind. Interest payments under the debentures are subordinated to the repayment of any amounts owing under the 
credit  facilities  and  are  not  permitted  if  the  Corporation  is  in  default  of  such  credit  facilities  or  if  the  amount  of  outstanding 
indebtedness under such facilities exceeds the then existing current borrowing base. For the year ended December 31, 2010, the 
average effective interest rate on the outstanding amounts under the facility was 5.0% (December 31, 2009 – 4.9%). Advantage 
also has issued letters of credit totaling $2.9 million at December 31, 2010 (December 31, 2009 – $1.3 million).

Asset Retirement Obligations 

The  Corporation’s  asset  retirement  obligations  result  from  net  ownership  interests  in  petroleum  and  natural  gas  properties 
including well sites, gathering systems and processing facilities. The Corporation estimates the total undiscounted amount of cash 
flows required to settle its asset retirement obligations is approximately $320 million which will be incurred between 2011 and 
2070.  A  credit-adjusted  risk-free  rate  of  7%  and  an  inflation  factor  of  2%  were  used  to  calculate  the  fair  value  of  the  asset 
retirement obligations.

Other Liability 

In August 2009, Advantage vacated an office location as the space was no longer required. Advantage is obligated to make lease 
payments for the remainder of the life of the lease, which terminates in November 2012. As a result, the full fair value of future 
scheduled lease payments was recognized as general and administrative expense in 2009 with a corresponding liability. Fair value 
was determined on a present value basis, using a credit-adjusted risk free rate of 7%. In November 2010, Advantage subleased a 
portion  of  the  space  to  a  subtenant,  and  accordingly  recognized  a  reduction  in  the  liability  and  a  corresponding  recovery  of 
general and administrative expense.

Concurrent  with  the  acquisition  of  Ketch  Resources  Trust  on  June  23,  2006,  the  Fund  internalized  the  external  management 
contract structure and eliminated all related fees for total original consideration of 1,933,208 Trust Units initially valued at $39.1 
million. These Trust Units were subject to escrow provisions over a three-year period, vesting one-third each year beginning in 
2007.  The  management  internalization  consideration  was  deferred  and  amortized  into  income  as  management  internalization 
expense over the specific vesting periods during which employee services were provided. For the year ended December 31, 2009, 
a  total  of  7,862  Trust  Units  issued  for  the  management  internalization  were  forfeited  and  $1.7  million  was  recognized  as 
management internalization expense. At December 31, 2010 and 2009, all Trust Units in respect of management internalization 
were issued and none remained held in escrow.   

Prior  to  converting  to  a  corporation  on  July  9,  2009,  1,263,158  Trust  Units  were  issued  under  the  Premium  Distribution(TM), 
Distribution Reinvestment and Optional Trust Unit Purchase Plan, generating $5.2 million reinvested in the Fund during the year 
ended December  31,  2009.    The  Premium  Distribution(TM),  Distribution  Reinvestment  and  Optional  Trust  Unit  Purchase  Plan 
was discontinued on March 18, 2009, concurrent with the discontinuation of cash distributions. 

The principal amount of 8.25% convertible debentures matured on February 1, 2009 and were settled by issuing 946,887 Trust 
Units. 

On July 7, 2009, the Fund closed a bought deal financing with 17 million Trust Units issued at $6.00 each, for gross proceeds of 
$102 million, less $3.8 million related to $5.2 million of issuance costs net $1.4 million of related future taxes.

Advantage has a Restricted Share Performance Incentive Plan (“RSPIP” or the “Plan”) as approved by the shareholders on July 9, 
2009, concurrent with the conversion to a corporation. The Plan authorizes the Board of Directors to grant restricted shares to 
service providers of the Corporation, including directors, officers, employees, and consultants. The number of restricted shares 
granted is based on the Corporation’s share price return for a twelve-month period and compared to the performance of a peer 
group  approved  by  the  Board  of  Directors.  The  share  price  return  is  calculated  at  the  end  of  each  and  every  quarter  and  is 
primarily based on the twelve-month change in the share price. If the share price return for a twelve-month period is positive, a 
restricted share grant will be calculated based on the return. If the share price return for a twelve-month period is negative, but 
the  return  is  still  within  the  top  two-thirds  of  the  approved  peer  group  performance,  the  Board  of  Directors  may  grant  a 
discretionary  restricted  share  award.  The  restricted  share  grants  generally  vest  one-third  immediately  on  grant  date,  with  the 
remaining two-thirds vesting evenly on the following two yearly anniversary dates. The holders of restricted shares may elect to 
receive cash upon vesting in lieu of the number of shares to be issued, subject to consent of the Corporation.  However, it is the 
intent to  settle unvested  amounts  with  shares.  The  Plan  replaced the  previous  Restricted Trust  Unit  (“RTU”)  plan  that was  in 
place prior to the conversion to a corporation and outstanding grants under the RTU are now subject to the RSPIP.   

In  conjunction  with  the  corporate  conversion,  a  transitional  award  of  restricted  shares  to  service  providers  was  approved  by 
shareholders valued at $5.80 per share or $8.4 million and to be issued in shares. The restricted shares were granted on September 
2, 2009 with the first one-quarter of the grant vesting immediately and the remaining three-quarters of the grant that will vest over 
the subsequent three anniversary dates. 

Total equity-based compensation recorded in general and administrative expenses during the year ended December 31, 2010 was 
$16.1 million, including a non-cash amount of $13.4 million (December 31, 2009 - $8.1 million, including a non-cash amount of 
$6.4 million). During the year ended December 31, 2010, 1,346,481 shares were issued in satisfaction of grants vesting under the 
RSPIP.    For  the  year  ended  December  31,  2009,  547,738  shares  were  issued  subsequent  to  the  corporate  conversion  in 
satisfaction  of  grants  vesting  under  the  RSPIP,  and  prior  to  the  corporate  conversion,  171,093  Trust  Units  were  issued  in 
satisfaction of grants vesting under the previous RTU plan.

In January 2011, an RSPIP grant was made to service providers valued at $6.95 per share or $0.5 million and is to be issued in 
shares.  No compensation expense was included in general and administrative expense as this grant occurred after December 31, 
2010.   

(e)  Net loss per share 

The calculations of basic and diluted net loss per share are derived from both net loss and weighted average shares outstanding, 
calculated as follows:

The calculation of diluted net loss per share excludes all series of convertible debentures for the years ended December 31, 2010 
and 2009 as the impact would be anti-dilutive. Total weighted average shares issuable in exchange for the convertible debentures 
and  excluded  from  the  diluted  net  loss  per  share  calculation  for  the  year  ended  December  31,  2010  was  14,401,412  shares 
(December 31, 2009 – 8,165,575 shares). As at December 31, 2010, the total convertible debentures outstanding were immediately 
convertible to 13,019,819 shares (December 31, 2009 – 15,821,382 shares). 

Restricted shares granted have been excluded from the calculation of diluted net loss per share for the years ended December 31, 
2010 and 2009, as the impact would have been anti-dilutive. Total weighted average shares issuable in exchange for the restricted 
shares  and  excluded  from  the  diluted  net  loss  per  share  calculation  for  the  year  ended  December  31,  2010  was  1,094,135 
(December 31, 2009 – 331,281).          

Management internalization escrowed Trust Units have been excluded from the calculations of diluted net loss per share for the 
year ended December 31, 2009 as the impact would be anti-dilutive. Total weighted average Trust Units issuable in exchange for 
the management internalization escrowed Trust Units and excluded from the diluted net loss per share calculation for the year 
ended December 31, 2009 was 207,018.

Financial Instruments 

Financial  instruments  of  the  Corporation  include  accounts  receivable,  deposits,  accounts  payable  and  accrued  liabilities,  bank 
indebtedness, convertible debentures, other liabilities and derivative assets and liabilities. 

Accounts receivable and deposits are classified as loans and receivables and measured at amortized cost. Accounts payable and 
accrued liabilities, bank indebtedness and other liabilities are all classified as other liabilities and similarly measured at amortized 
cost.  As at December 31, 2010, there were no significant differences between the carrying amounts reported on the balance sheet 
and the estimated fair values of these financial instruments due to the short terms to maturity and the floating interest rate on the 
bank indebtedness.  

The Corporation has convertible debenture obligations outstanding, of which the liability component has been classified as other 
liabilities  and  measured  at  amortized  cost.  The  convertible  debentures  have  different  fixed  terms  and  interest  rates  (note  5) 
resulting in fair values that will vary over time as market conditions change. As at December 31, 2010, the estimated fair value of 
the total outstanding convertible debenture obligation was $153.2 million (December 31, 2009 - $207.9 million). The fair value of 
the  convertible  debentures  was  determined  by  a  Level  2  valuation  model,  based  on  discounted  cash  flows  assuming  no  future 
conversions and continuation of current interest and principal payments as well as taking into consideration the current public 
trading activity of such debentures.  The Corporation applied discount rates of between 5% and 7% considering current available 
market information, assumed credit adjustments, and various terms to maturity.  

Advantage  has  an  established  strategy  to  manage  the  risk  associated  with  changes  in  commodity  prices  by  entering  into 
derivatives, which are recorded at fair value as derivative assets and liabilities with gains and losses recognized through earnings. 
As the fair value of the contracts varies with commodity prices, they give rise to financial assets and liabilities. The fair values of 
the derivatives are determined by a Level 2 valuation model, where pricing inputs other than quoted prices in an active market are 
used.    These  pricing  inputs  include  quoted forward  prices  for  commodities,  foreign  exchange  rates,  volatility  and  risk-free  rate 
discounting, all of which can be observed or corroborated in the marketplace. The actual gains and losses realized on eventual 
cash settlement can vary materially due to subsequent fluctuations in commodity prices and foreign exchange rates as compared 
to the valuation assumptions. 

Credit Risk 

Accounts receivable, deposits, and derivative assets are subject to credit risk exposure and the total carrying value of $70.4 million 
(December 31, 2009 - $92.0 million) reflects Management’s assessment of the associated maximum exposure to such credit risk. 
Advantage  mitigates  such  credit  risk  by  closely  monitoring  significant  counterparties  and  dealing  with  a  broad  selection  of 
partners  that  diversify  risk  within  the  sector.  The  Corporation’s  deposits  are  primarily  due  from  the  Alberta  Provincial 
government  and  are  viewed  by  Management  as  having  minimal  associated  credit  risk.  To  the  extent  that  Advantage  enters 
derivatives to manage commodity price risk, it may be subject to credit risk associated with counterparties with which it contracts. 
Credit risk is mitigated by entering into contracts with only stable, creditworthy parties and through frequent reviews of exposures 
to individual entities. In addition, the Corporation only enters into derivative contracts with major banks and international energy 
firms to further mitigate associated credit risk. 

Substantially all of the Corporation’s accounts receivable are due from customers and joint operation partners concentrated in the 
Canadian oil and gas industry. As such, accounts receivable have been subject to normal industry credit risks.  As at December 31, 
2010, $2.3 million or 5.4% of accounts receivable have been outstanding for 90 days or more (December 31, 2009 - $6.9 million 
or  12.6%  of  accounts  receivable).  The  Corporation  believes  that  the  entire  balance  is  collectible,  and  in  some  instances  the 
Corporation  has  the  ability  to  mitigate  risk  through  withholding  production  or  offsetting  payables  with  the  same  parties. 
Management has provided for an allowance for doubtful accounts of $0.2 million at December 31, 2010 (December 31, 2009 – 
$0.5 million).

Financial Instruments (continued) 

Liquidity Risk 

The Corporation is subject to liquidity risk attributed from accounts payable and accrued liabilities, bank indebtedness, convertible 
debentures, other liabilities, and derivative liabilities. Accounts payable and accrued liabilities, and derivative liabilities are primarily 
due within one year of the balance sheet date and Advantage does not anticipate any problems in satisfying the obligations from 
cash  provided  by  operating  activities  and  the  existing  credit  facility.  The  Corporation’s  bank  indebtedness  is  subject  to  a  $525 
million credit facility agreement (note 6) and does not have specific maturity dates. Under the terms of the agreement, the facility 
is reviewed annually, with the next review scheduled in June 2011. The credit facility constitutes a revolving facility for a 364 day 
term  which  is  extendible  annually  for  a  further  364  day  revolving  period  at  the  option  of  the  syndicate.  If  not  extended,  the 
revolving  credit  facility  is  converted  to  a  one  year  term  facility  with  the  principal  payable  at  the  end  of  such  one  year  term. 
Management  fully  expects  that  the  facility  will  be  extended  at  each  annual  review.  Although  the  credit  facility  is  a  source  of 
liquidity risk, the facility also mitigates liquidity risk by enabling Advantage to manage interim cash flow fluctuations. The terms of 
the credit facility are such that it provides Advantage adequate flexibility to evaluate and assess liquidity issues if and when they 
arise. Additionally, the Corporation regularly monitors liquidity related to obligations by evaluating forecasted cash flows, optimal 
debt levels, capital spending activity, working capital requirements, and other potential cash expenditures. This continual financial 
assessment process further enables the Corporation to mitigate liquidity risk. 

Advantage has several series of convertible debentures outstanding that mature in 2011 and 2015 (note 5). Interest payments are 
made semi-annually with excess cash provided by operating activities. As the debentures become due, the Corporation can satisfy 
the obligations in cash or issue shares at a price determined in the applicable debenture indentures. This settlement alternative 
allows the Corporation to adequately manage liquidity, plan available cash resources and implement an optimal capital structure. 

To the extent that Advantage enters derivatives to manage commodity price risk, it may be subject to liquidity risk as derivative 
liabilities become due. While the Corporation has elected not to follow hedge accounting, derivative instruments are not entered 
for speculative purposes and Management closely monitors existing commodity risk exposures. As such, liquidity risk is mitigated 
since any losses actually realized are subsidized by increased cash flows realized from the higher commodity price environment.

Interest on bank indebtedness was calculated assuming conversion of the revolving credit facility to a one-year term facility.

Interest Rate Risk 
The  Corporation  is  exposed  to  interest  rate  risk  to  the  extent  that  bank  indebtedness  is  at  a  floating  rate  of  interest  and  the 
Corporation’s maximum exposure to interest rate risk is based on the effective interest rate and the current carrying value of the 
bank indebtedness. The Corporation monitors the interest rate markets to ensure that appropriate steps can be taken if interest 
rate volatility compromises the Corporation’s cash flows. A 1% increase in interest rates for the year ended December 31, 2010 
could have increased net loss for the year by approximately $1.9 million (December 31, 2009 - $3.4 million). 

Price and Currency Risk 

Advantage’s  derivative  assets  and  liabilities  are  subject  to  both  price  and  currency  risks  as  their  fair  values  are  based  on 
assumptions  including  forward  commodity  prices  and  foreign  exchange  rates.  The  Corporation  enters  derivative  financial 
instruments  to  manage  commodity  price  risk  exposure  relative to  actual  commodity  production  and  does  not  utilize  derivative 
instruments  for  speculative  purposes.  Changes  in  the  price  assumptions  can  have  a  significant  effect  on  the  fair  value  of  the 
derivative assets and liabilities and thereby impact net loss. It is estimated that a 10% increase in the forward natural gas prices 
used  to  calculate  the  fair  value  of  the natural  gas  derivatives  at  December  31,  2010  could  increase  net  loss  for  the  year  ended 
December 31, 2010 by approximately $2.7 million (December 31, 2009 - $7.1 million). As well, an increase of 10% in the forward 
crude oil prices used to calculate the fair value of the crude oil derivatives at December 31, 2010 could increase net loss for the 
year ended December 31, 2010 by $4.0 million (December 31, 2009 - $4.7 million). A similar magnitude increase in the forward 
currency rate assumption underlying the derivatives fair value does not materially increase net loss. 

As at December 31, 2010 the Corporation had the following derivatives in place:

As  at  December  31,  2010,  the  fair  value  of  the  derivatives  outstanding  resulted  in  an  asset  of  approximately  $25.2  million 
(December 31, 2009 – $31.1 million) and a liability of approximately $2.5 million (December 31, 2009 – $13.9 million). For the 
year  ended  December  31,  2010,  $5.4  million  was  recognized  in  net  loss  as  an  unrealized derivative  gain  (December  31,  2009  - 
$23.7 million unrealized derivative loss) and $45.1 million was recognized in net loss as a realized derivative gain (December 31, 
2009 – $86.5 million realized derivative gain).

Capital Management 

The Corporation manages its capital with the following objectives: 

•  To  ensure  sufficient  financial  flexibility  to  achieve  the  ongoing  business  objectives  including  replacement  of  production, 

funding of future growth opportunities, and pursuit of accretive acquisitions; and 

•  To maximize shareholder return through enhancing the share value. 

Advantage monitors its capital structure and makes adjustments according to market conditions in an effort to meet its objectives 
given  the  current  outlook  of  the  business  and  industry  in  general.  The  capital  structure  of  the  Corporation  is  composed  of 
working capital (excluding derivative assets and liabilities), bank indebtedness, convertible debentures, capital lease obligations and 
shareholders’  equity.    Advantage  may  manage  its  capital  structure  by  issuing  new  shares,  repurchasing  outstanding  shares, 
obtaining  additional  financing  either  through  bank  indebtedness  or  convertible  debenture  issuances,  refinancing  current  debt, 
issuing  other  financial  or  equity-based  instruments,  declaring  a  dividend,  implementing  a  dividend  reinvestment  plan,  adjusting 
capital  spending,  or  disposing  of  assets.    The  capital  structure  is  reviewed  by  Management  and  the  Board  of  Directors  on  an 
ongoing basis.  Advantage’s capital structure is as follows:

The  Corporation’s  bank  indebtedness  is  governed  by  a  $525  million  credit  facility  agreement  (note  6)  that  contains  standard 
commercial  covenants  for  facilities  of  this  nature.    The  only  financial  covenant  is  a  requirement  for  Advantage  to  maintain  a 
minimum  cash  flow  to  interest  expense  ratio  of  3.5:1,  determined  on  a  rolling  four  quarter  basis.  This  covenant  was  met  at 
December 31, 2010 and 2009. As well, the borrowing base for the Corporation’s credit facilities is determined through utilizing 
Advantage’s  regular  reserve  estimates.  The  banking  syndicate  thoroughly  evaluates  the  reserve  estimates  based  upon  their  own 
commodity price expectations to determine the amount of the borrowing base. Revision or changes in the reserve estimates and 
commodity prices can have either a positive or a negative impact on the borrowing base of the Corporation.   

Management of the Corporation’s capital structure is facilitated through its financial and operational forecasting processes.  The 
forecast  of  the  Corporation’s  future  cash  flows  is  based  on  estimates  of  production,  commodity  prices,  forecast  capital  and 
operating expenditures, and other investing and financing activities. The forecast is regularly updated based on new commodity 
prices and other changes, which the Corporation views as critical in the current environment.  Selected forecast information is 
frequently provided to the Board of Directors.   

The  Corporation’s  capital  management  objectives,  policies  and  processes  have  remained  unchanged  during  the  year  ended 
December 31, 2010.

Subsequent Events 

On March 7, 2011, Advantage announced that Longview Oil Corp. (“Longview”), a wholly-owned subsidiary of the Corporation, 
filed a  preliminary  prospectus on  March  4,  2011  for  an  initial  public  offering  (the “Offering”),  which  is targeted  to  raise  gross 
proceeds  of  $150  million  prior  to  an  over-allotment  option.    The  closing  of  the  Offering  is  expected  to  occur  in  April,  2011.  
Concurrent with closing of the Offering, Longview will purchase certain oil-weighted assets from Advantage (the “Transaction”), 
with  consideration  comprised  of  the  net  proceeds  of  the  Offering,  an  equity  ownership  interest  of  approximately  68% 
(approximately 63% if the over-allotment option is exercised in full) of the common shares of Longview and proceeds of $100 
million to be drawn from an independent Longview credit facility. Advantage plans to use the cash proceeds from the Transaction 
to  reduce  outstanding  bank  indebtedness.  The  Transaction  is  conditional  upon  customary  industry  conditions  including  the 
approval of the Board of Directors of Advantage.

Reconciliation of Financial Statements to United States Generally Accepted Accounting Principles  

The  consolidated  financial  statements  of  Advantage  have  been  prepared  in  accordance  with  accounting  principles  generally 
accepted in Canada. Canadian GAAP, in most respects, conforms to generally accepted accounting principles in the United States 
(“US  GAAP”).  Significant  differences  in  accounting  principles  between  Canadian  GAAP  and  US  GAAP,  as  they  apply  to 
Advantage, are as described below.  

(a)  Equity-based compensation 

Advantage accounts for compensation expense based on the fair value of the equity awards on the grant date and the initial fair 
value is not subsequently remeasured. Prior to converting to a corporation, the Fund’s equity-based compensation consisted of a 
Restricted Trust Unit Plan and Trust Units held in escrow subject to service requirement provisions.  Advantage’s current equity-
based compensation consists of a Restricted Share Performance Incentive Plan. The initial fair value is expensed over the vesting 
period of the grants.  

Under US GAAP, the Corporation adopted ASC 718 “Stock compensation” on January 1, 2006 using the modified prospective 
approach and applies the fair value method of accounting for all equity-based compensation granted after January 1, 2006. Prior 
to  converting  to  a  corporation,  a  US  GAAP  difference  existed  as  grants  of  Trust  Unit  compensation  were  considered  liability 
awards for US GAAP and equity awards for Canadian GAAP. Under US GAAP, the fair value of a liability award is measured at 
the grant date and is subsequently remeasured at each reporting period. When the Trust Unit grants vested, the amount recorded 
as  a  liability  was  recognized  as  temporary  equity.    Upon  conversion  to  a  corporation,  all  equity-based  compensation  are  now 
considered equity awards under both US and Canadian GAAP.  Accordingly, there is no US GAAP difference with respect to 
equity-based compensation awards granted subsequent to conversion to a corporation. 

(b)  Convertible debentures and issuance costs 

The  Corporation  applies  CICA  3863  “Financial  Instruments  –  Presentation”  in  accounting  for  convertible  debentures  which 
results in their classification as liabilities. The convertible debentures also have an embedded conversion feature which must be 
segregated between liabilities and equity, based on the residual value method, where the liability is first measured using a discount 
rate  without  the  conversion  feature  and  the  remaining  amount  is  allocated  to  equity.    Therefore,  the  debenture  liabilities  are 
presented at less than their eventual maturity values. The liability and equity components are further reduced for issuance costs 
initially incurred. The discount of the liability component, net of issuance costs, as compared to maturity value is accreted by the 
effective interest method over the debenture term. As debentures are converted to shares, an appropriate portion of the liability 
and equity components are transferred to share capital. Interest and accretion expense on the convertible debentures are shown 
on the Consolidated Statements of Loss. 

Advantage Oil & Gas Ltd. - 56 

 
 
 
       
       
         
         
 
Under  US  GAAP,  convertible  debentures  issued  after  the  corporate  conversion  are  shown  as  a  liability.  The  embedded 
conversion feature is not accounted for separately as a component of equity. Given that the convertible debentures are carried at 
maturity value, it is not necessary to accrete the balance over the term of the debentures which results in an expense reduction as 
compared  to  Canadian  GAAP.  For  the  year  ended  December  31,  2009,  the  Corporation  implemented  retrospectively  changes 
prescribed  by  ASC  470  “Debt”  which  became  effective  for  years  beginning  after  December  15,  2008.  As  a  result,  for  all 
convertible debentures that existed prior to the corporate conversion, the instruments were divided into a liability and an equity 
component, similar to Canadian GAAP treatment, and opening Shareholders’ Equity was increased $3.5 million. 

Additionally, under US GAAP, issuance costs related to liabilities are generally shown as a deferred charge rather than netted from 
the carrying value and are amortized to interest expense over the term of the liability. 

(c)  Depletion and depreciation 

For Canadian GAAP, depletion of petroleum and natural gas properties and depreciation of lease and well equipment is provided 
on accumulated costs using the unit-of-production method based on estimated proved petroleum and natural gas reserves, before 
royalties, based on forecast prices and costs. 

US GAAP provides for a similar accounting methodology except that estimated proved petroleum and natural gas reserves are net 
of  royalties  and  based  on  the  first-day-of-month  average  prices  for  the  prior  twelve  months  (“constant  prices”).  Therefore, 
depletion and depreciation under US GAAP will be different since changes to royalty rates will impact both proved reserves and 
production  and  differences  between  constant  prices  as  compared  to  forecast  prices  will  impact  proved  reserve  volumes. 
Additionally, differences in depletion and depreciation will result in divergence of net book value for Canadian GAAP and US 
GAAP from year-to-year and impact future depletion and depreciation expense as well as the net book value utilized for future 
impairment calculations. 

(d)  Impairment of Petroleum and Natural Gas Properties 

Under Canadian GAAP, petroleum and natural gas properties are evaluated each reporting period to determine that the carrying 
amount  is  recoverable  and  does  not exceed  the  fair  value  of the  properties  in  the cost centre (the  “ceiling  test”).  The carrying 
amounts  are  assessed  to  be  recoverable  when  the  sum  of  the  undiscounted  net  cash  flows  expected  from  the  production  of 
proved reserves, the lower of cost and market of unproved properties and the cost of major development projects exceeds the 
carrying amount of the cost centre. When the carrying amount is not assessed to be recoverable, an impairment loss is recognized 
to the extent that the carrying amount of the cost centre exceeds the sum of the discounted net cash flows expected from the 
production  of  proved  and  probable  reserves,  the  lower  of  cost  and  market  of  unproved  properties  and  the  cost  of  major 
development  projects  of  the  cost  centre.  The  cash  flows  are  estimated  using  expected  future  product  prices  and  costs  and  are 
discounted using a risk-free interest rate. For Canadian GAAP purposes, Advantage has not recognized an impairment loss since 
inception. 

Under US GAAP, the carrying amounts of petroleum and natural gas properties, net of deferred income taxes, shall not exceed an 
amount equal to the sum of the present value of estimated net future after-tax cash flows of proved reserves at constant prices 
and costs computed using a discount factor of ten percent plus the lower of cost or estimated fair value of unproved properties. 
Any excess is charged to expense as an impairment loss through depletion, depreciation and accretion expense. Under US GAAP, 
Advantage recognized impairment losses of $49.5 million in 2001 ($28.3 million net of tax), $535.4 million in 2006 ($477.8 million 
net of tax), $1,047.5 million in 2008 ($770.8 million net of tax), and $303.9 million in 2009 ($227.4 million net of tax). Impairment 
losses  decrease  net  book  value  of  petroleum  and  natural  gas  properties  which  reduces  depletion  and  depreciation  expense 
subsequently recorded as well as future potential impairment calculations.  

(e)  Income tax 

The future income tax accounting standard under Canadian GAAP is substantially similar to the deferred income tax approach as 
required  by  US  GAAP.  Pursuant  to  Canadian  GAAP,  substantively  enacted  tax  rates  are  used  to  calculate  future  income  tax, 
whereas US GAAP applies enacted tax rates. However, there were no tax rate differences for the years ended December 31, 2010 
and  2009.  The  differences  between  Canadian  GAAP  and  US  GAAP  relate  to  future  income  tax  impacts  on  other  GAAP 
differences. 

Under Canadian GAAP as at December 31, 2010, the Corporation’s carrying value of its net assets exceeded its tax bases and 
resulted in a future income tax liability.  Adjustments under US GAAP result in a large future income tax recovery and a future 
income tax asset, as the impairment significantly lowered the Corporation’s fixed assets carrying value under US GAAP.

(f)  Goodwill 

Under  Canadian  and  US  GAAP,  the  Corporation  is  required  to  test  the  carrying  amount  of  goodwill  at  each  balance  sheet 
reporting  date  and  the  methodologies  are  substantially  the  same.  However,  the  carrying  value  of  the  reporting  unit  (the 
Corporation) under US GAAP is much lower due to the impairments to fixed assets required under US GAAP (note 15(d)). For 
the year ended December 31, 2008, goodwill was determined to be fully impaired, and was therefore written down to Nil under 
Canadian GAAP.  However, under US GAAP, the fair value of the reporting unit (the Corporation) was in excess of its carrying 
values and no impairment of goodwill was recorded for the year ended December 31, 2008.  For the years ended December 31, 
2010 and 2009, the fair value of the reporting unit continued to be in excess of carrying values as determined under US GAAP 
and no impairment of goodwill was recorded. 

(g)  Shareholders’ equity 

Since  converting  to  a  corporation  on  July  9,  2009,  Shareholders’  Equity  of  Advantage  consists  primarily  of  shares.    For  both 
Canadian and US GAAP, the shares are considered permanent equity and presented as a component of Shareholders’ equity. 

Prior to conversion to a corporation, the Trust Units of the Fund were redeemable at any time on demand by the holders, which 
was required for the Fund to retain its Canadian mutual fund trust status. The holders were entitled to receive a price per Trust 
Unit equal to the lesser of: (i) 85% of the simple average of the closing market prices of the Trust Units, on the principal market 
on which the Trust Units were quoted for trading, during the 10 trading-day period commencing immediately after the date on 
which the Trust Units were surrendered for redemption; and (ii) the closing market price on the principal market on which the 
Trust  Units  were  quoted  for trading  on  the  redemption  date.  For  Canadian  GAAP  purposes, the Trust  Units  were considered 
permanent equity and were presented as a component of Unitholders’ equity. 

Under US GAAP, it is required that equity with a redemption feature be presented as temporary equity between the liability and 
equity sections of the balance sheet. Therefore, prior to the corporate conversion temporary equity was shown at an amount equal 
to the redemption value based on the terms of the Trust Units and all components of Unitholders’ equity related to Trust Units 
was eliminated. Changes in the redemption value from year-to-year was charged to deficit. For the year ended December 31, 2009, 
shareholders’ equity was increased by $130.8 million corresponding to changes in the Trust Units redemption value from January 
1,  2009  to  July  8,  2009.    On  July  9,  2009,  the  entire  recorded  value  of  temporary  equity  of  $660.1  million  was  transferred  to 
permanent equity concurrent with the corporate conversion. 

A  continuity  schedule  of  significant  equity  accounts  for  each  reporting  period  is  required  disclosure  under  US  GAAP.  The 
following table is a continuity of shareholders’ equity, the Corporation’s only significant equity account:
