during 2009 , the company converted its stock administration system to a new service provider .
in connection with this conversion , a reconciliation of the methodologies and estimates utilized was performed , which resulted in a $ 12 million reduction of expense for the year ended december 31 , 2009 .
stock awards stock awards , in the form of rsus , are granted to certain employees and consist of both performance-based and service-based rsus .
service-based awards generally vest between three and ten years from the date of grant .
the fair value of service-based awards is based upon the market value of the underlying common stock at the date of grant .
with certain limited exceptions , any break in continuous employment will cause the forfeiture of all unvested awards .
compensation expense associated with stock awards is recognized over the service period .
dividend equivalents are paid on certain service-based rsus , based on the initial grant amount .
performance-based rsus have been granted to certain employees .
vesting of these awards is contingent upon meeting various individual , divisional or company-wide performance conditions , including revenue generation or growth in revenue , pretax income or earnings per share over a one- to five-year period .
the performance conditions are not considered in the determination of the grant date fair value for these awards .
the fair value of performance-based awards is based upon the market price of the underlying common stock at the date of grant .
compensation expense is recognized over the performance period , and in certain cases an additional vesting period , based on management 2019s estimate of the number of units expected to vest .
compensation expense is adjusted to reflect the actual number of shares paid out at the end of the programs .
the actual payout of shares under these performance- based plans may range from 0-200% ( 0-200 % ) of the number of units granted , based on the plan .
dividend equivalents are generally not paid on the performance-based rsus .
during 2010 , the company granted approximately 1.6 million shares in connection with the completion of the 2007 leadership performance plan ( 2018 2018lpp 2019 2019 ) cycle and 84000 shares related to other performance plans .

segments and geographic information the segment reporting structure uses the company's organizational structure as its foundation to reflect how the company manages the businesses internally and is organized by geographic regions which provides a socio- political-economic understanding of our business .
during the third quarter of 2017 , the europe and asia sbus were merged in order to leverage scale and are now reported as part of the eurasia sbu .
the management reporting structure is organized by five sbus led by our president and chief executive officer : us , andes , brazil , mcac and eurasia sbus .
the company determined that it has five operating and five reportable segments corresponding to its sbus .
all prior period results have been retrospectively revised to reflect the new segment reporting structure .
in february 2018 , we announced a reorganization as a part of our ongoing strategy to simplify our portfolio , optimize our cost structure , and reduce our carbon intensity .
the company is currently evaluating the impact this reorganization will have on our segment reporting structure .
corporate and other 2014 corporate overhead costs which are not directly associated with the operations of our five reportable segments are included in "corporate and other." also included are certain intercompany charges such as self-insurance premiums which are fully eliminated in consolidation .
the company uses adjusted ptc as its primary segment performance measure .
adjusted ptc , a non-gaap measure , is defined by the company as pre-tax income from continuing operations attributable to the aes corporation excluding gains or losses of the consolidated entity due to ( a ) unrealized gains or losses related to derivative transactions ; ( b ) unrealized foreign currency gains or losses ; ( c ) gains , losses and associated benefits and costs due to dispositions and acquisitions of business interests , including early plant closures ; ( d ) losses due to impairments ; ( e ) gains , losses and costs due to the early retirement of debt ; and ( f ) costs directly associated with a major restructuring program , including , but not limited to , workforce reduction efforts , relocations , and office consolidation .
adjusted ptc also includes net equity in earnings of affiliates on an after-tax basis adjusted for the same gains or losses excluded from consolidated entities .
the company has concluded adjusted ptc better reflects the underlying business performance of the company and is the most relevant measure considered in the company's internal evaluation of the financial performance of its segments .
additionally , given its large number of businesses and complexity , the company concluded that adjusted ptc is a more transparent measure that better assists investors in determining which businesses have the greatest impact on the company's results .
revenue and adjusted ptc are presented before inter-segment eliminations , which includes the effect of intercompany transactions with other segments except for interest , charges for certain management fees , and the write-off of intercompany balances , as applicable .
all intra-segment activity has been eliminated within the segment .
inter-segment activity has been eliminated within the total consolidated results .

all prior period results have been retrospectively revised to reflect the new segment reporting structure .
in february 2018 , we announced a reorganization as a part of our ongoing strategy to simplify our portfolio , optimize our cost structure , and reduce our carbon intensity .
the company is currently evaluating the impact this reorganization will have on our segment reporting structure .
corporate and other 2014 corporate overhead costs which are not directly associated with the operations of our five reportable segments are included in "corporate and other." also included are certain intercompany charges such as self-insurance premiums which are fully eliminated in consolidation .
the company uses adjusted ptc as its primary segment performance measure .
adjusted ptc , a non-gaap measure , is defined by the company as pre-tax income from continuing operations attributable to the aes corporation excluding gains or losses of the consolidated entity due to ( a ) unrealized gains or losses related to derivative transactions ; ( b ) unrealized foreign currency gains or losses ; ( c ) gains , losses and associated benefits and costs due to dispositions and acquisitions of business interests , including early plant closures ; ( d ) losses due to impairments ; ( e ) gains , losses and costs due to the early retirement of debt ; and ( f ) costs directly associated with a major restructuring program , including , but not limited to , workforce reduction efforts , relocations , and office consolidation .
adjusted ptc also includes net equity in earnings of affiliates on an after-tax basis adjusted for the same gains or losses excluded from consolidated entities .
the company has concluded adjusted ptc better reflects the underlying business performance of the company and is the most relevant measure considered in the company's internal evaluation of the financial performance of its segments .
additionally , given its large number of businesses and complexity , the company concluded that adjusted ptc is a more transparent measure that better assists investors in determining which businesses have the greatest impact on the company's results .
revenue and adjusted ptc are presented before inter-segment eliminations , which includes the effect of intercompany transactions with other segments except for interest , charges for certain management fees , and the write-off of intercompany balances , as applicable .
all intra-segment activity has been eliminated within the segment .
inter-segment activity has been eliminated within the total consolidated results .
the following tables present financial information by segment for the periods indicated ( in millions ) : .
