The  difference  between  both  the  methods  of  measuring  inventory  is  the  way  in  which  the  cost  of  goods  sold  is  calculated.  A  company  ideally  does  not  keep  a  track  of  every  single  piece  of  incoming  and  outgoing  goods  hence  it  is  required  to  calculate  the  inventory  at  the  end  of  an  accounting  period.  There  are  two  methods  of  calculating  the  inventory  that  is  FIFO  and  LIFO.  Fifo  means  first  in  first  out,  so whatever  goods  come  in  first  are  sold  in  the  same  order.  Hence  the  goods  that  were  purchased  last  will  remain  in  the  inventory.  In  case  of  LIFO,  the  goods  which  come  in  at  last  are  sold  first.  The  first  purchases  will  generally  remain  in  the  inventory.    Whatever  comes  in  as  purchase  or  production  is  sold.  Most  recently  acquired  items  are  sold  first.  An  example  of  a  hypothetical  firm  is  shown  below.  Its  effects  on  accounting  can  be  seen  below.
In  case  of  FIFO,  the  goods  at  the  beginning  of  the  period  will be  sold  first  and  the  inventory  will consist  of  goods  purchased  on  Oct  15.  It  is  also  assumed  that  the  beginning  inventory  is  4000  units.  Hence  the  initial  sales  will  be  from  the  beginning  inventory  followed  by  the  purchases.  The  inventory  for  the  same  under  FIFO  is  4500  units.  As  for  LIFO,  the  sales  will  be  from  the  purchase  of  17  Jan  and  not  from  the  beginning  inventory.  The  inventory  for  the  period  will  be  4500  units  including  beginning  inventory.  Though  the  units  in  both  the  cases  are  same,  its  value  will  be  different  because  of  the  different  prices  at  which  the  goods  have  been  purchased.  In  case  of  FIFO,  the  value  of  inventory  will  be  $33000  and  in  case  of  LIFO,  the  same  will  be  $25000.  This  is  the  basic  difference  between  the  two  methods  of  inventory  valuation.
The  impact  of  FIFO  on  the  current  assets  can  be  seen  in  case  of  rising  prices  and  falling  prices.  So  if  the  prices  are  rising  and  a  firm  is  using  FIFO  method,  the  inventory  will  be  high  and  the  cost  of  goods  sold  will  be  low  due  to  which  the  profits  will  be  high.  The  current  assets  will  also  be  high.  The  overall  profit  will   show  a  reduction.  In  case  a  firm  using  FIFO  is  going  through  a  fall  in  prices,  the  inventory  will  be  low  and  so  will  the  current  assets  be.  The  overall  profits  will  be  high  because  of  the  higher  cost  of  goods  sold.  The  gross  profit  has  a  direct  impact  of  the  inventory  valuation  method.
The  impact  of  LIFO  can  be  similarly  seen,  in  case   of  rising  prices  the  inventory  value  will  be  low  and  the  current  assets  will  also  be  low.  The  gross  profit  will  be  low  as  the  cost  of  goods  sold  will  be  high.  LIFO  shows  opposite  and  inverse  effect  from  FIFO.  In  case  of  falling  prices,  LIFO  will  show  a  higher  ending  inventory  with  a  high  current  asset  and  a  high  gross  profit.  This  happens  due  to  a  lower  value  of  cost  of  goods  sold.    Many  a  times  accountants  manipulate  the  inventory  so  as  show  a  lower  gross  profit.   To  avoid  the  occurrence  of  such  events,  the  Board  has  provided  accounting  guidelines  which  require  the  firms  to  provide  a  method  of  valuation  and  stick  to  the  same  unless  advised  by  the  Board.  Inventory  has  a  dual  effect,  on  the  profit  as  well  as  the  current  assets.  It  changes  the  balance  sheet  if  a  small  change  in  inventory  is  noticed.
Two  annual  reports  namely  Virgin  Media  and  Cheniere  Energy  Inc.  are  taken  here.  The  analysis  of  the  footnotes  of  the  reports  is  provided  further.  As  for  Cheniere  Energy  Inc.  the  footnotes  provide  information  about  the  equity  and  liability  information.  The  equity  consists  of  the  stock  issued  and  outstanding,  the  equity  shares  have  been  issued  during  2013  and  they  show  a  slight  increase  as  compared  to  the  previous  year.  The  treasury  stock  which  is  maintained  as  a  reserve  by  the  company  has  shown  a  deficit.  The  deficit  has  increased  over  the  year.  The  equity  section  also  shows  an  additional  capital  which  was  paid  for  including  the  total  deficit  during  the  period.  The  total  amount  of  shareholders  equity  has  been  provided  which  includes  the  initial  issued  capital  and  the  deficit  along  with  the  paid  up  capital.  The  value  for  the  shareholders  equity  shares  have  been  given.  As  for  liabilities,  the  company  has  mentioned  all  the  liabilities  as  long  term,  short  term  and  current  liabilities.  Along  with  the  shareholders  equity,  the  total  liability  has  been  shown  which  includes  all  the  liabilities  of  the  company  and  the  equity  part  of  the  same.  The  company  has  also  shown  noncontrolling  interest  which  is  the  investment  it  has  in  other  equity  but  does  not  hold  any  control  over  the  same.  Thus,  other  than  current  liabilities  the  long  term  and  short  term  debt  has  been  specifically  shown.
In  case  of  Virgin  Media,  the  analysis  of  financial  statements  show  that  the  equity  of  the  company  has  shown  common  stock  and  additional  paid  up  capital.  The  accumulated  deficit  is  also  seen  in  the  balance  sheet  which  is  added  to  the  equity and  the  total  of  equity  holdings  and  liabilities  is  shown.  Equity  includes  share  based  compensation,  dividends,  repurchase  of  common  stock  and  effect  of  share  based  compensations.  Thus  the  total  amount  of  equity  reflects  all  the  transactions  which  took  place  in  the  shares  of  the  company.  The  liabilities  are  again  divided  into  account  payables,  long  term  debts,  interest  and  related  party  payables.  The  specific  headings  show  the  amount  to  be  paid.  It  also  includes  the  current  portion  of  the  debt  and  lease  obligations  which  are  to  be  paid  in  the  coming   period.  The  liabilities  include  derivative  instruments  which  are  affected  due  to  changes  in  the  currency  rates.  The  effect  on  assets  due  to  the  interest  rate  and  cross  currency  rates  is  seen.
A  note  also  provides  details  about  the  debt  and  lease  obligations,  the  fair  value  and  carrying  value  are  shown  which  reflect  the  amount  of  convertible  notes,  credit  facility  and  vendor  financing.  The  company  has  111  shares  of  common  stock  outstanding.  The  company  received  a  cash  contribution  which  was   used  to  repay  a  facility  agreement.  The  company  also  received  non  cash  contribution  in  relation  to  deferred  financing  cost  and  in  relation  to  transfer  of  shares  to  a  trust  in  exchange  for  a  note.  The  company  mentions  that  it  has  not  issued  any  common  stock  nor  has  it  repurchased  the  same.  Thus  the  total  equity  and  liabilities  show  the  total  amount  attributable  to  the  shareholders  and  the  liability  of  the  company.  It  basically  consists  of  various  transactions  carried  out  throughout  the  year.  The  notes  provide  details  of  the  same.
