Notes:  Data are for calendar years with these exceptions:  1965 and 1966, year ended 9/30; 1967, 15 months ended 12/31. 

Starting  in  1979,  accounting  rules  required  insurance  companies  to  value  the  equity  securities  they  hold  at  market 
rather  than  at  the  lower  of  cost  or  market,  which  was  previously  the  requirement.    In  this  table,  Berkshire’s  results 
through 1978 have been restated to conform to the changed rules.  In all other respects, the results are calculated using 
the numbers originally reported. 

The S&P 500 numbers are pre-tax whereas the Berkshire numbers are after-tax.  If a corporation such as Berkshire 
were simply to have owned the S&P 500 and accrued the appropriate taxes, its results would have lagged the S&P 500 
in  years  when  that  index  showed  a  positive  return,  but  would  have  exceeded  the  S&P  500  in  years  when  the  index 
showed a negative return.  Over the years, the tax costs would have caused the aggregate lag to be substantial.

BERKSHIRE HATHAWAY INC. 

To the Shareholders of Berkshire Hathaway Inc.: 

Our gain in net worth during 2006 was $16.9 billion, which increased the per-share book value of 
both our Class A and Class B stock by 18.4%.  Over the last 42 years (that is, since present management 
took over) book value has grown from $19 to $70,281, a rate of 21.4% compounded annually.* 

We  believe  that  $16.9  billion  is  a  record  for  a  one-year  gain  in  net  worth  –  more  than  has  ever 
been booked by any American business, leaving aside boosts that have occurred because of mergers (e.g., 
AOL’s  purchase  of  Time  Warner).    Of  course,  Exxon  Mobil  and  other  companies  earn  far  more  than 
Berkshire, but their earnings largely go to dividends and/or repurchases, rather than to building net worth. 

All  that  said,  a  confession  about  our  2006  gain  is  in  order.    Our  most  important  business, 
insurance, benefited from a large dose of luck:  Mother Nature, bless her heart, went on vacation.  After 
hammering  us  with  hurricanes  in  2004  and  2005  –  storms  that  caused  us  to  lose  a  bundle  on  super-cat 
insurance – she just vanished.  Last year, the red ink from this activity turned black – very black. 

In addition, the great majority of our 73 businesses did outstandingly well in 2006.  Let me focus 
for a moment on one of our largest operations, GEICO.  What management accomplished there was simply 
extraordinary. 

As I’ve told you before, Tony Nicely, GEICO’s CEO, went to work at the company 45 years ago, 
two months after turning 18.  He became CEO in 1992, and from then on the company’s growth exploded.  
In addition, Tony has delivered staggering productivity gains in recent years.  Between yearend 2003 and 
yearend  2006,  the  number  of  GEICO  policies  increased  from  5.7  million  to  8.1  million,  a  jump  of  42%.  
Yet during that same period, the company’s employees (measured on a fulltime-equivalent basis) fell 3.5%.  
So productivity grew 47%.  And GEICO didn’t start fat. 

That  remarkable  gain  has  allowed  GEICO  to  maintain  its  all-important  position  as  a  low-cost 
producer, even though it has dramatically increased advertising expenditures.  Last year GEICO spent $631 
million  on  ads,  up  from  $238  million  in  2003  (and  up  from  $31  million  in  1995,  when  Berkshire  took 
control).  Today, GEICO spends far more on ads than any of its competitors, even those much larger.  We 
will continue to raise the bar. 

Last year I told you that if you had a new son or grandson to be sure to name him Tony.  But Don 
Keough, a Berkshire director, recently had a better idea.  After reviewing GEICO’s performance in 2006, 
he  wrote  me,  “Forget  births.    Tell  the  shareholders  to  immediately  change  the  names  of  their  present 
children to Tony or Antoinette.”  Don signed his letter “Tony.” 

* * * * * * * * * * * * 

Charlie Munger – my partner and Berkshire’s vice chairman – and I run what has turned out to be 
a big business, one with 217,000 employees and annual revenues approaching $100 billion.  We certainly 
didn’t plan it that way.  Charlie began as a lawyer, and I thought of myself as a security analyst.  Sitting in 
those seats, we both grew skeptical about the ability of big entities of any type to function well.  Size seems 
to make many organizations slow-thinking, resistant to change and smug.  In Churchill’s words: “We shape 
our buildings, and afterwards our buildings shape us.”  Here’s a telling fact: Of the ten non-oil companies 
having  the  largest  market  capitalization  in  1965  –  titans  such  as  General  Motors,  Sears,  DuPont  and 
Eastman Kodak – only one made the 2006 list.   

*All per-share figures used in this report apply to Berkshire’s A shares.  Figures for the B shares 

are 1/30th of those shown for the A.

In fairness, we’ve seen plenty of successes as well, some truly outstanding.  There are many giant-
company managers whom I greatly admire; Ken Chenault of American Express, Jeff Immelt of G.E. and 
Dick Kovacevich of Wells Fargo come quickly to mind.  But I don’t think I could do the management job 
they  do.    And  I  know  I  wouldn’t  enjoy  many  of  the  duties  that  come  with  their  positions  –  meetings, 
speeches,  foreign  travel,  the  charity  circuit  and  governmental  relations.    For  me,  Ronald  Reagan  had  it 
right: “It’s probably true that hard work never killed anyone – but why take the chance?” 

So I’ve taken the easy route, just sitting back and working through great managers who run their 
own shows.  My only tasks are to cheer them on, sculpt and harden our corporate culture, and make major 
capital-allocation decisions.  Our managers have returned this trust by working hard and effectively. 

For  their  performance  over  the  last  42  years  –  and  particularly  for  2006  –  Charlie  and  I  thank 

them. 

Yardsticks 

Charlie and I measure Berkshire’s progress and evaluate its intrinsic value in a number of ways. 
No single criterion is effective in doing these jobs, and even an avalanche of statistics will not capture some 
factors that are important.  For example, it’s essential that we have managers much younger than I available 
to succeed me.  Berkshire has never been in better shape in this regard – but I can’t prove it to you with 
numbers. 

There  are  two  statistics,  however,  that  are  of  real  importance.    The  first  is  the  amount  of 
investments (including cash and cash-equivalents) that we own on a per-share basis.  Arriving at this figure, 
we  exclude  investments  held  in  our  finance  operation  because  these  are  largely  offset  by  borrowings.  
Here’s the record since present management acquired control of Berkshire:

*Net of minority interests 

In  our  early  years  we  put  most  of  our  retained  earnings  and  insurance  float  into  investments  in 
marketable  securities.    Because  of  this  emphasis,  and  because  the  securities  we  purchased  generally  did 
well, our growth rate in investments was for a long time quite high. 

Over  the  years,  however,  we  have  focused  more  and  more  on  the  acquisition  of  operating 
businesses.  Using our funds for these purchases has both slowed our growth in investments and accelerated 
our  gains  in  pre-tax  earnings  from  non-insurance  businesses,  the  second  yardstick  we  use.    Here’s  how 
those earnings have looked:

*Excluding purchase-accounting adjustments and net of minority interests 

Last year we had a good increase in non-insurance earnings – 38%.  Large gains from here on in, 
though, will come only if we are able to make major, and sensible, acquisitions.  That will not be easy.  We 
do,  however,  have  one  advantage:  More  and  more,  Berkshire  has  become  “the  buyer  of  choice”  for 
business owners and managers.  Initially, we were viewed that way only in the U.S. (and more often than 
not  by  private  companies).    We’ve  long  wanted,  nonetheless,  to  extend  Berkshire’s  appeal  beyond  U.S. 
borders.  And last year, our globe-trotting finally got underway. 

Acquisitions 

We began 2006 by completing the three acquisitions pending at yearend 2005, spending about $6 

billion for PacifiCorp, Business Wire and Applied Underwriters.  All are performing very well. 

The  highlight  of  the  year,  however,  was  our  July  5th  acquisition  of  most  of  ISCAR,  an  Israeli 
company,  and  our  new  association  with  its  chairman,  Eitan  Wertheimer,  and  CEO,  Jacob  Harpaz.    The 
story here began on October 25, 2005, when I received a 1¼-page letter from Eitan, of whom I then knew 
nothing.  The letter began, “I am writing to introduce you to ISCAR,” and proceeded to describe a cutting-
tool business carried on in 61 countries.  Then Eitan wrote, “We have for some time considered the issues 
of generational transfer and ownership that are typical for large family enterprises, and have given much 
thought  to  ISCAR’s  future.    Our  conclusion  is  that  Berkshire  Hathaway  would  be  the  ideal  home  for 
ISCAR.  We believe that ISCAR would continue to thrive as a part of your portfolio of businesses.” 

Overall, Eitan’s letter made the quality of the company and the character of its management leap 
off  the  page.    It  also  made  me  want  to  learn  more,  and  in  November,  Eitan,  Jacob  and  ISCAR’s  CFO, 
Danny Goldman, came to Omaha.  A few hours with them convinced me that if we were to make a deal, we 
would be teaming up with extraordinarily talented managers who could be trusted to run the business after 
a  sale  with  all  of  the  energy  and  dedication  that  they  had  exhibited  previously.    However,  having  never 
bought a business based outside of the U.S. (though I had bought a number of foreign stocks), I needed to 
get educated on some tax and jurisdictional matters.  With that task completed, Berkshire purchased 80% of 
ISCAR  for  $4  billion.    The  remaining  20%  stays  in  the  hands  of  the  Wertheimer  family,  making  it  our 
valued partner. 

ISCAR’s products are small, consumable cutting tools that are used in conjunction with large and 
expensive machine tools.  It’s a business without magic except for that imparted by the people who run it.  
But Eitan, Jacob and their associates are true managerial magicians who constantly develop tools that make 
their  customers’  machines  more  productive.    The  result:  ISCAR  makes  money  because  it  enables  its 
customers to make more money.  There is no better recipe for continued success.

In September, Charlie and I, along with five Berkshire associates, visited ISCAR in Israel.  We – 
and  I  mean  every  one  of  us  –  have  never  been  more  impressed  with  any  operation.    At  ISCAR,  as 
throughout Israel, brains and energy are ubiquitous.  Berkshire shareholders are lucky to have joined with 
Eitan, Jacob, Danny and their talented associates. 

* * * * * * * * * * * * 

A few months later, Berkshire again became “the buyer of choice” in a deal brought to us by my 
friend, John Roach, of Fort Worth.  John, many of you will remember, was Chairman of Justin Industries, 
which  we  bought  in  2000.    At  that  time  John  was  helping  John  Justin,  who  was  terminally  ill,  find  a 
permanent home for his company.  John Justin died soon after we bought Justin Industries, but it has since 
been run exactly as we promised him it would be. 

Visiting me in November, John Roach brought along Paul Andrews, Jr., owner of about 80% of 
TTI,  a  Fort  Worth  distributor  of  electronic  components.    Over  a  35-year  period,  Paul  built  TTI  from 
$112,000 of sales to $1.3 billion.  He is a remarkable entrepreneur and operator. 

Paul, 64, loves running his business.  But not long ago he happened to witness how disruptive the 
death of a founder can be both to a private company’s employees and the owner’s family.  What starts out 
as disruptive, furthermore, often evolves into destructive.  About a year ago, therefore, Paul began to think 
about selling TTI.  His goal was to put his business in the hands of an owner he had carefully chosen, rather 
than allowing a trust officer or lawyer to conduct an auction after his death. 

Paul rejected the idea of a “strategic” buyer, knowing that in the pursuit of “synergies,” an owner 
of that type would be apt to dismantle what he had so carefully built, a move that would uproot hundreds of 
his associates (and perhaps wound TTI’s business in the process).  He also ruled out a private equity firm, 
which would very likely load the company with debt and then flip it as soon as possible. 

That  left  Berkshire.    Paul  and  I  met  on  the  morning  of  November  15th  and  made  a  deal  before 
lunch.  Later he wrote me: “After our meeting, I am confident that Berkshire is the right owner for TTI . . . 
I am proud of our past and excited about our future.”  And so are Charlie and I. 

* * * * * * * * * * * * 

We  also  made  some  “tuck-in”  acquisitions  during  2006  at  Fruit  of  the  Loom  (“Fruit”),  MiTek, 
CTB,  Shaw  and  Clayton.    Fruit  made  the  largest  purchases.    First,  it  bought  Russell  Corp.,  a  leading 
producer of athletic apparel and uniforms for about $1.2 billion (including assumed debt) and in December 
it  agreed  to  buy  the  intimate  apparel  business  of  VF  Corp.    Together,  these  acquisitions  add  about  $2.2 
billion to Fruit’s sales and bring with them about 23,000 employees. 

Charlie and I love it when we can acquire businesses that can be placed under managers, such as 
John Holland at Fruit, who have already shown their stuff at Berkshire.  MiTek, for example, has made 14 
acquisitions since we purchased it in 2001, and Gene Toombs has delivered results from these deals far in 
excess of what he had predicted.  In effect, we leverage the managerial talent already with us by these tuck-
in deals.  We will make many more. 

We continue, however, to need “elephants” in order for us to use Berkshire’s flood of incoming 
cash.    Charlie  and I  must  therefore  ignore  the  pursuit  of mice  and  focus  our  acquisition  efforts  on much 
bigger game.

Our exemplar is the older man who crashed his grocery cart into that of a much younger fellow 
while both were shopping.  The elderly man explained apologetically that he had lost track of his wife and 
was  preoccupied  searching  for  her.    His  new  acquaintance  said  that  by  coincidence  his  wife  had  also 
wandered  off  and  suggested  that  it  might  be  more  efficient  if  they  jointly  looked  for  the  two  women.  
Agreeing, the older man asked his new companion what his wife looked like.  “She’s a gorgeous blonde,” 
the  fellow  answered,  “with  a  body  that would  cause  a bishop  to go  through  a  stained  glass  window,  and 
she’s  wearing  tight  white  shorts.    How  about  yours?”    The  senior  citizen  wasted  no  words:  “Forget  her, 
we’ll look for yours.”

call me – day or night.  And then watch me shatter a stained glass window. 

Now, let’s examine the four major operating sectors of Berkshire.  Lumping their financial figures 
together  impedes  analysis.    So  we’ll  look  at  them  as  four  separate  businesses,  starting  with  the  all–
important insurance group.

Insurance 

Next  month  marks  the  40th  anniversary  of  our  entrance  into  the  insurance  business.    It  was  on 
March 9, 1967, that Berkshire purchased National Indemnity and its companion company, National Fire & 
Marine, from Jack Ringwalt for $8.6 million. 

Jack was a long-time friend of mine and an excellent, but somewhat eccentric, businessman.  For 
about  ten  minutes  every  year  he  would  get  the  urge  to  sell  his  company.    But  those  moods  –  perhaps 
brought on by a tiff with regulators or an unfavorable jury verdict – quickly vanished. 

In the mid-1960s, I asked investment banker Charlie Heider, a mutual friend of mine and Jack’s, 
to alert me the next time Jack was “in heat.”  When Charlie’s call came, I sped to meet Jack.  We made a 
deal in a few minutes, with me waiving an audit, “due diligence” or anything else that would give Jack an 
opportunity to reconsider.  We just shook hands, and that was that. 

When we were due to close the purchase at Charlie’s office, Jack was late.  Finally arriving, he 
explained that he had been driving around looking for a parking meter with some unexpired time.  That was 
a magic moment for me.  I knew then that Jack was going to be my kind of manager. 

When Berkshire purchased Jack’s two insurers, they had “float” of $17 million.  We’ve regularly 
offered a long explanation of float in earlier reports, which you can read on our website.  Simply put, float 
is money we hold that is not ours but which we get to invest. 

At  the  end  of  2006,  our  float  had  grown  to  $50.9  billion,  and  we  have  since  written  a  huge 
retroactive reinsurance contract with Equitas – which I will describe in the next section – that boosts float 
by another $7 billion.  Much of the gain we’ve made has come through our acquisition of other insurers, 
but we’ve also had outstanding internal growth, particularly at Ajit Jain’s amazing reinsurance operation.  
Naturally, I had no notion in 1967 that our float would develop as it has.  There’s much to be said for just 
putting one foot in front of the other every day. 

The  float  from  retroactive  reinsurance  contracts,  of  which  we  have  many,  automatically  drifts 
down over time.  Therefore, it will be difficult for us to increase float in the future unless we make new 
acquisitions in the insurance field.  Whatever its size, however, the all-important cost of Berkshire’s float 
over  time  is  likely  to  be  significantly  below  that  of  the  industry,  perhaps  even  falling  to  less  than  zero.  
Note the words “over time.”  There will be bad years periodically.  You can be sure of that. 

In 2006, though, everything went right in insurance – really right.  Our managers – Tony Nicely 
(GEICO),  Ajit  Jain  (B-H  Reinsurance),  Joe  Brandon  and  Tad  Montross  (General  Re),  Don  Wurster 
(National  Indemnity  Primary),  Tom  Nerney  (U.S.  Liability),  Tim  Kenesey  (Medical  Protective),  Rod 
Eldred (Homestate Companies and Cypress), Sid Ferenc and Steve Menzies (Applied Underwriters), John 
Kizer (Central States) and Don Towle (Kansas Bankers Surety) – simply shot the lights out.  When I recite 
their names, I feel as if I’m at Cooperstown, reading from the Hall of Fame roster.  Of course, the overall 
insurance industry also had a terrific year in 2006.  But our managers delivered results generally superior to 
those of their competitors.

In 2007, our results  from  the  bread-and-butter  lines  of  insurance will  deteriorate,  though I  think 
they will remain satisfactory.  The big unknown is super-cat insurance.  Were the terrible hurricane seasons 
of 2004-05 aberrations?  Or were they our planet’s first warning that the climate of the 21st Century will 
differ materially from what we’ve seen in the past?  If the answer to the second question is yes, 2006 will 
soon be perceived as a misleading period of calm preceding a series of devastating storms.  These could 
rock the insurance industry.  It’s naïve to think of Katrina as anything close to a worst-case event. 

Neither Ajit Jain, who manages our super-cat operation, nor I know what lies ahead.  We do know 
that it would be a huge mistake to bet that evolving atmospheric changes are benign in their implications 
for insurers. 

Don’t think, however, that we have lost our taste for risk.  We remain prepared to lose $6 billion 
in a single event, if we have been paid appropriately for assuming that risk.  We are not willing, though, to 
take  on  even  very  small  exposures  at  prices  that  don’t  reflect  our  evaluation  of  loss  probabilities.  
Appropriate  prices  don’t  guarantee  profits  in  any  given  year,  but  inappropriate  prices  most  certainly 
guarantee eventual losses.  Rates have recently fallen because a flood of capital has entered the super-cat 
field.  We have therefore sharply reduced our wind exposures.  Our behavior here parallels that which we 
employ in financial markets: Be fearful when others are greedy, and be greedy when others are fearful. 

Lloyd’s, Equitas and Retroactive Reinsurance 

Last  year  –  we  are  getting  now  to  Equitas  –  Berkshire  agreed  to  enter  into  a  huge  retroactive 
reinsurance contract, a policy that protects an insurer against losses that have already happened, but whose 
cost is not yet known.  I’ll give you details of the agreement shortly.  But let’s first take a journey through 
insurance history, following the route that led to our deal. 

Our  tale  begins  around  1688,  when  Edward  Lloyd  opened  a  small  coffee  house  in  London.  
Though  no  Starbucks,  his  shop  was  destined  to  achieve  worldwide  fame  because  of  the  commercial 
activities  of  its  clientele  –  shipowners,  merchants  and  venturesome  British  capitalists.    As  these  parties 
sipped  Edward’s  brew,  they  began  to  write  contracts  transferring  the  risk  of  a  disaster  at  sea  from  the 
owners of ships and their cargo to the capitalists, who wagered that a given voyage would be completed 
without incident.  These capitalists eventually became known as “underwriters at Lloyd’s.” 

Though  many  people  believe  Lloyd’s  to  be  an  insurance  company,  that  is  not  the  case.    It  is 

instead a place where many member-insurers transact business, just as they did centuries ago. 

Over  time,  the  underwriters  solicited  passive  investors  to  join  in  syndicates.    Additionally,  the 
business  broadened  beyond  marine  risks  into  every  imaginable  form  of  insurance,  including  exotic 
coverages  that  spread  the  fame  of  Lloyd’s  far  and  wide.    The  underwriters  left  the  coffee  house,  found 
grander quarters and formalized some rules of association.  And those persons who passively backed the 
underwriters became known as “names.” 

8

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Eventually,  the  names  came  to  include  many  thousands  of  people  from  around  the  world,  who 
joined expecting to pick up some extra change without effort or serious risk.  True, prospective names were 
always solemnly told that they would have unlimited and everlasting liability for the consequences of their 
syndicate’s  underwriting  –  “down  to  the  last  cufflink,”  as  the  quaint  description  went.    But  that  warning 
came to be viewed as perfunctory.  Three hundred years of retained cufflinks acted as a powerful sedative 
to the names poised to sign up. 

Then came asbestos.  When its prospective costs were added to the tidal wave of environmental 
and product claims that surfaced in the 1980s, Lloyd’s began to implode.  Policies written decades earlier – 
and largely forgotten about – were developing huge losses.  No one could intelligently estimate their total, 
but  it  was  certain  to  be  many  tens  of  billions  of  dollars.    The  specter  of  unending  and  unlimited  losses 
terrified existing names and scared away prospects.  Many names opted for bankruptcy; some even chose 
suicide. 

From  these  shambles,  there came  a  desperate  effort  to resuscitate  Lloyd’s.    In 1996, the  powers 
that  be  at  the  institution  allotted  £11.1  billion  to  a  new  company,  Equitas,  and  made  it  responsible  for 
paying  all  claims  on  policies  written  before  1993.    In  effect,  this  plan  pooled  the  misery  of  the  many 
syndicates in trouble.  Of course, the money allotted could prove to be insufficient – and if that happened, 
the names remained liable for the shortfall. 

But  the  new  plan,  by  concentrating  all  of  the  liabilities  in  one  place,  had  the  advantage  of 
eliminating  much  of  the  costly  intramural  squabbling  that  went  on  among  syndicates.    Moreover,  the 
pooling allowed claims evaluation, negotiation and litigation to be handled more intelligently than had been 
the case previously.  Equitas embraced Ben Franklin’s thinking: “We must all hang together, or assuredly 
we shall hang separately.”  

From the start, many people predicted Equitas would eventually fail.  But as Ajit and I reviewed 
the  facts  in  the  spring  of  2006  –  13  years  after  the  last  exposed  policy  had  been  written  and  after  the 
payment  of  £11.3  billion  in  claims  –  we  concluded  that  the  patient  was  likely  to  survive.    And  so  we 
decided to offer a huge reinsurance policy to Equitas. 

Because  plenty  of  imponderables  continue  to  exist,  Berkshire  could  not  provide  Equitas,  and  its 
27,972  names,  unlimited  protection.    But  we  said  –  and  I’m  simplifying  –  that  if  Equitas  would  give  us 
$7.12 billion in cash and securities (this is the float I spoke about), we would pay all of its future claims and 
expenses up to $13.9 billion.  That amount was $5.7 billion above what Equitas had recently guessed its 
ultimate  liabilities  to  be.    Thus  the  names  received  a  huge  –  and  almost  certainly  sufficient  –  amount  of 
future protection against unpleasant surprises.  Indeed the protection is so large that Equitas plans a cash 
payment to its thousands of names, an event few of them had ever dreamed possible. 

And how will Berkshire fare?  That depends on how much “known” claims will end up costing us, 
how many yet-to-be-presented claims will surface and what they will cost, how soon claim payments will 
be made and how much we earn on the cash we receive before it must be paid out.  Ajit and I think the odds 
are in our favor.  And should we be wrong, Berkshire can handle it. 

Scott  Moser,  the  CEO  of  Equitas,  summarized  the  transaction  neatly:  “Names  wanted  to  sleep 

easy at night, and we think we’ve just bought them the world’s best mattress.” 

Warning: It’s time to eat your broccoli – I am now going to talk about accounting matters.  I owe 
this to those Berkshire shareholders who love reading about debits and credits.  I hope both of you find this 
discussion helpful.  All others can skip this section; there will be no quiz. 

* * * * * * * * * * * 

Berkshire has done many retroactive transactions – in both number and amount a multiple of such 
policies entered into by any other insurer.  We are the reinsurer of choice for these coverages because the 
obligations that are transferred to us – for example, lifetime indemnity and medical payments to be made to 
injured workers – may not be fully satisfied for 50 years or more.  No other company can offer the certainty  

9

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
that Berkshire can, in terms of guaranteeing the full and fair settlement of these obligations.  This fact is 
important to the original insurer, policyholders and regulators. 

The  accounting  procedure  for  retroactive  transactions  is  neither  well  known  nor  intuitive.    The 
best  way  for  shareholders  to  understand  it,  therefore,  is  for  us  to  simply  lay  out  the  debits  and  credits.  
Charlie and I would like to see this done more often.  We sometimes encounter accounting footnotes about 
important transactions that leave us baffled, and we go away suspicious that the reporting company wished 
it  that  way.    (For  example,  try  comprehending  transactions  “described”  in  the  old  10-Ks  of  Enron,  even 
after you know how the movie ended.) 

So let us summarize our accounting for the Equitas transaction.  The major debits will be to Cash 
and  Investments,  Reinsurance  Recoverable,  and  Deferred  Charges  for  Reinsurance  Assumed  (“DCRA”).  
The  major  credit  will  be  to Reserve  for  Losses  and  Loss  Adjustment  Expense.   No profit or  loss will  be 
recorded at the inception of the transaction, but underwriting losses will thereafter be incurred annually as 
the DCRA asset is amortized downward.  The amount of the annual amortization charge will be primarily 
determined  by  how  our  end-of-the-year  estimates  as  to  the  timing  and  amount  of  future  loss  payments 
compare to the estimates made at the beginning of the year.  Eventually, when the last claim has been paid, 
the DCRA account will be reduced to zero.  That day is 50 years or more away. 

What’s important to remember is that retroactive insurance contracts always produce underwriting 
losses for us.  Whether these losses are worth experiencing depends on whether the cash we have received 
produces investment income that exceeds the losses.  Recently our DCRA charges have annually delivered 
$300  million  or  so  of  underwriting  losses,  which  have  been  more  than  offset  by  the  income  we  have 
realized through use of the cash we received as a premium.  Absent new retroactive contracts, the amount 
of the annual charge would normally decline over time.  After the Equitas transaction, however, the annual 
DCRA  cost  will  initially  increase  to  about  $450  million  a  year.    This  means  that  our  other  insurance 
operations  must  generate  at  least  that  much  underwriting  gain  for  our  overall  float  to  be  cost-free.    That 
amount is quite a hurdle but one that I believe we will clear in many, if not most, years. 

Aren’t you glad that I promised you there would be no quiz?

This motley group, which sells products ranging from lollipops to motor homes, earned a pleasing 
25% on average tangible net worth last year.  It’s noteworthy also that these operations used only minor 
financial leverage in achieving that return.  Clearly we own some terrific businesses.  We purchased many 
of  them,  however,  at  large  premiums  to  net  worth –  a point  reflected  in the  goodwill  item  shown on the 
balance sheet – and that fact reduces the earnings on our average carrying value to 10.8%. 

Here are a few newsworthy items about companies in this sector: 

•  Bob  Shaw,  a  remarkable  entrepreneur  who  from  a  standing  start  built  Shaw  Industries  into  the 
country’s  largest  carpet  producer,  elected  last  year,  at  age  75,  to  retire.    To  succeed  him,  Bob 
recommended  Vance  Bell,  a  31-year  veteran  at  Shaw,  and  Bob,  as  usual,  made  the  right  call.  
Weakness  in  housing  has  caused  the  carpet  business  to  slow.    Shaw,  however,  remains  a 
powerhouse and a major contributor to Berkshire’s earnings. 

•  MiTek,  a  manufacturer  of  connectors  for  roof  trusses  at  the  time  we  purchased  it  in  2001,  is 
developing  into  a  mini-conglomerate.    At  the  rate  it  is  growing,  in  fact,  “mini”  may  soon  be 
inappropriate.   In purchasing  MiTek for $420  million, we  lent  the  company  $200  million  at 9% 
and bought $198 million of stock, priced at $10,000 per share.  Additionally, 55 employees bought 
2,200  shares  for  $22  million.    Each  employee  paid  exactly  the  same  price  that  we  did,  in  most 
cases borrowing money to do so. 

And  are  they  ever  glad  they  did!    Five  years  later,  MiTek’s  sales  have  tripled  and  the  stock  is 
valued at $71,699 per share.  Despite its making 14 acquisitions, at a cost of $291 million, MiTek 
has  paid  off  its  debt  to  Berkshire  and  holds  $35  million  of  cash.    We  celebrated  the  fifth 
anniversary of our purchase with a party in July.  I told the group that it would be embarrassing if 
MiTek’s stock price soared beyond that of Berkshire “A” shares.  Don’t be surprised, however, if 
that happens (though Charlie and I will try to make our shares a moving target). 

•  Not  all  of  our  businesses  are  destined  to  increase  profits.    When  an  industry’s  underlying 
economics are crumbling, talented management may slow the rate of decline.  Eventually, though, 
eroding fundamentals will overwhelm managerial brilliance.  (As a wise friend told me long ago, 
“If you want to get a reputation as a good businessman, be sure to get into a good business.”)  And 
fundamentals are definitely eroding in the newspaper industry, a trend that has caused the profits 
of our Buffalo News to decline.  The skid will almost certainly continue. 

When Charlie and I were young, the newspaper business was as easy a way to make huge returns 
as existed in America.  As one not-too-bright publisher famously said, “I owe my fortune to two 
great American institutions: monopoly and nepotism.”  No paper in a one-paper city, however bad 
the product or however inept the management, could avoid gushing profits. 

The  industry’s  staggering  returns  could  be  simply  explained.    For  most  of  the  20th  Century, 
newspapers were the primary source of information for the American public.  Whether the subject 
was sports, finance, or politics, newspapers reigned supreme.  Just as important, their ads were the 
easiest way to find job opportunities or to learn the price of groceries at your town’s supermarkets.   

11

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
The  great  majority  of  families  therefore  felt  the  need  for  a  paper  every  day,  but  understandably 
most didn’t wish to pay for two.  Advertisers preferred the paper with the most circulation, and 
readers tended to want the paper with the most ads and news pages.  This circularity led to a law 
of the newspaper jungle: Survival of the Fattest.  

Thus, when two or more papers existed in a major city (which was almost universally the case a 
century  ago),  the  one  that  pulled  ahead  usually  emerged  as  the  stand-alone  winner.    After 
competition  disappeared,  the  paper’s  pricing  power  in  both  advertising  and  circulation  was 
unleashed.    Typically,  rates  for both  advertisers  and  readers  would  be  raised  annually  –  and  the 
profits rolled in.  For owners this was economic heaven.  (Interestingly, though papers regularly – 
and often in a disapproving way – reported on the profitability of, say, the auto or steel industries, 
they never enlightened readers about their own Midas-like situation.  Hmmm . . .) 

As long ago as my 1991 letter to shareholders, I nonetheless asserted that this insulated world was 
changing, writing that “the media businesses . . . will prove considerably less marvelous than I, the 
industry,  or  lenders  thought  would  be  the  case  only  a  few  years  ago.”    Some  publishers  took 
umbrage  at both  this  remark and  other warnings  from  me  that  followed.    Newspaper  properties, 
moreover, continued to sell as if they were indestructible slot machines.  In fact, many intelligent 
newspaper  executives  who  regularly  chronicled  and  analyzed  important  worldwide  events  were 
either blind or indifferent to what was going on under their noses.  

Now, however, almost all newspaper owners realize that they are constantly losing ground in the 
battle  for  eyeballs.    Simply  put,  if  cable  and  satellite  broadcasting,  as  well  as  the  internet,  had 
come along first, newspapers as we know them probably would never have existed. 

In  Berkshire’s  world,  Stan  Lipsey  does  a  terrific  job  running  the  Buffalo  News,  and  I  am 
enormously  proud  of  its  editor,  Margaret  Sullivan.    The  News’  penetration  of  its  market  is  the 
highest  among  that  of  this  country’s  large newspapers.   We  also  do better  financially  than  most 
metropolitan  newspapers,  even  though  Buffalo’s  population  and  business  trends  are  not  good.  
Nevertheless, this operation faces unrelenting pressures that will cause profit margins to slide. 

True, we have the leading online news operation in Buffalo, and it will continue to attract more 
viewers and ads.  However, the economic potential of a newspaper internet site – given the many 
alternative sources of information and entertainment that are free and only a click away – is at best 
a small fraction of that existing in the past for a print newspaper facing no competition. 

For  a  local resident, ownership  of  a  city’s paper,  like ownership  of  a sports  team,  still  produces 
instant prominence.  With it typically comes power and influence.  These are ruboffs that appeal to 
many  people  with  money.    Beyond  that,  civic-minded,  wealthy  individuals  may  feel  that  local 
ownership  will  serve  their  community  well.  That’s  why  Peter  Kiewit  bought  the  Omaha  paper 
more than 40 years ago. 

We are likely therefore to see non-economic individual buyers of newspapers emerge, just as we 
have  seen  such  buyers  acquire  major  sports  franchises.    Aspiring  press  lords  should  be  careful, 
however: There’s no rule that says a newspaper’s revenues can’t fall below its expenses and that 
losses can’t mushroom.  Fixed costs are high in the newspaper business, and that’s bad news when 
unit volume heads south.  As the importance of newspapers diminishes, moreover, the “psychic” 
value of possessing one will wane, whereas owning a sports franchise will likely retain its cachet. 

Unless we face an irreversible cash drain, we will stick with the News, just as we’ve said that we 
would.  (Read economic principle 11, on page 76.)  Charlie and I love newspapers – we each read 
five a day – and believe that a free and energetic press is a key ingredient for maintaining a great 
democracy.    We  hope  that  some  combination  of  print  and  online  will  ward  off  economic 
doomsday  for  newspapers,  and  we  will  work  hard  in  Buffalo  to  develop  a  sustainable  business 
model.  I think we will be successful.  But the days of lush profits from our newspaper are over.

•  A  much  improved  situation  is  emerging  at  NetJets,  which  sells  and  manages  fractionally-owned 
aircraft.  This company has never had a problem growing: Revenues from flight operations have 
increased 596% since our purchase in 1998.  But profits had been erratic. 

Our  move  to  Europe,  which  began  in  1996,  was  particularly  expensive.    After  five  years  of 
operation there, we had acquired only 80 customers.  And by mid-year 2006 our cumulative pre-
tax  loss had  risen  to $212  million.    But  European demand has now  exploded, with  a net  of 589 
customers having been added in 2005-2006.  Under Mark Booth’s brilliant leadership, NetJets is 
now operating profitably in Europe, and we expect the positive trend to continue. 

Our U.S. operation also had a good year in 2006, which led to worldwide pre-tax earnings of $143 
million at NetJets last year.  We made this profit even though we suffered a loss of $19 million in 
the first quarter. 

Credit Rich Santulli, along with Mark, for this turnaround.  Rich, like many of our managers, has 
no  financial  need  to  work.    But  you’d  never  know  it.    He’s  absolutely  tireless  –  monitoring 
operations, making sales, and traveling the globe to constantly widen the already-enormous lead 
that  NetJets  enjoys over  its  competitors.    Today,  the value  of  the fleet  we  manage  is far greater 
than that managed by our three largest competitors combined. 

There’s  a  reason  NetJets  is  the  runaway  leader:  It  offers  the  ultimate  in  safety  and  service.    At 
Berkshire, and at a number of our subsidiaries, NetJets aircraft are an indispensable business tool.  
I  also  have  a  contract  for  personal  use  with  NetJets  and  so  do  members  of  my  family  and  most 
Berkshire  directors.    (None  of  us,  I  should  add,  gets  a  discount.)    Once  you’ve  flown  NetJets, 
returning to commercial flights is like going back to holding hands. 

Regulated Utility Business 

Berkshire has an 86.6% (fully diluted) interest in MidAmerican Energy Holdings, which owns a 
wide variety of utility operations.  The largest of these are (1) Yorkshire Electricity and Northern Electric, 
whose  3.7  million  electric  customers  make  it  the  third  largest  distributor  of  electricity  in  the  U.K.;  (2) 
MidAmerican Energy, which serves 706,000 electric customers, primarily in Iowa; (3) Pacific Power and 
Rocky  Mountain  Power,  serving  about  1.7  million  electric  customers  in  six  western  states;  and  (4)  Kern 
River and Northern Natural pipelines, which carry about 8% of the natural gas consumed in the U.S. 

Our partners in ownership of MidAmerican are Walter Scott, and its two terrific managers, Dave 
Sokol and Greg Abel.  It’s unimportant how many votes each party has; we will make major moves only 
when we are unanimous in thinking them wise.  Six years of working with Dave, Greg and Walter have 
underscored my original belief: Berkshire couldn’t have better partners. 

Somewhat incongruously, MidAmerican owns the second largest real estate brokerage firm in the 
U.S.,  HomeServices  of  America.    This  company  operates  through  20  locally-branded  firms  with  20,300 
agents.    Despite  HomeServices’  purchase  of  two  operations  last  year,  the  company’s  overall  volume  fell 
9% to $58 billion, and profits fell 50%. 

The slowdown in residential real estate activity stems in part from the weakened lending practices 
of recent years.  The “optional” contracts and “teaser” rates that have been popular have allowed borrowers 
to make payments in the early years of their mortgages that fall far short of covering normal interest costs.  
Naturally, there are few defaults when virtually nothing is required of a borrower.  As a cynic has said, “A 
rolling  loan  gathers  no  loss.”    But  payments  not  made  add  to  principal,  and  borrowers  who  can’t  afford 
normal monthly payments early on are hit later with above-normal monthly obligations.  This is the Scarlett 
O’Hara scenario: “I’ll think about that tomorrow.”  For many home owners, “tomorrow” has now arrived.  
Consequently there is a huge overhang of offerings in several of HomeServices’ markets. 

Nevertheless,  we  will  be  seeking  to  purchase  additional  brokerage  operations.    A  decade  from 

now, HomeServices will almost certainly be much larger.

Finance and Financial Products 

You  will  be  happy  to  hear  –  and  I’m  even  happier  –  that  this  will  be  my  last  discussion  of  the 
losses at Gen Re’s derivative operation.  When we started to wind this business down early in 2002, we had 
23,218 contracts outstanding.  Now we have 197.  Our cumulative pre-tax loss from this operation totals 
$409 million, but only $5 million occurred in 2006.  Charlie says that if we had properly classified the $409 
million on our 2001 balance sheet, it would have been labeled “Good Until Reached For.”  In any event, a 
Shakespearean  thought  –  slightly  modified  –  seems  appropriate  for  the  tombstone  of  this  derivative 
business: “All’s well that ends.” 

We’ve also wound up our investment in Value Capital.  So earnings or losses from these two lines 

of business are making their final appearance in the table that annually appears in this section. 

Clayton  Homes  remains  an  anomaly  in  the  manufactured-housing  industry,  which  last  year 
recorded its lowest unit sales since 1962.  Indeed, the industry’s volume last year was only about one-third 
that of 1999.  Outside of Clayton, I doubt if the industry, overall, made any money in 2006. 

Yet Clayton earned $513 million pre-tax and paid Berkshire an additional $86 million as a fee for 
our obtaining the funds to finance Clayton’s $10 billion portfolio of installment receivables.  Berkshire’s 
financial strength has clearly been of huge help to Clayton.  But the driving force behind the company’s 
success is Kevin Clayton.  Kevin knows the business forward and backward, is a rational decision-maker 
and a joy to work with.  Because of acquisitions, Clayton now employs 14,787 people, compared to 6,661 
at the time of our purchase. 

We  have  two  leasing  operations:  CORT  (furniture),  run  by  Paul  Arnold,  and  XTRA  (truck 
trailers), run by Bill Franz.  CORT’s earnings improved significantly last year, and XTRA’s remained at 
the high level attained in 2005.  We continue to look for tuck-in acquisitions to be run by Paul or Bill, and 
also are open to ideas for new leasing opportunities.

We are delighted by the 2006 business performance of virtually all of our investees.  Last year, we 
told you that our expectation was that these companies, in aggregate, would increase their earnings by 6% 
to 8% annually, a rate that would double their earnings every ten years or so.  In 2006 American Express,

9%, 8% and 11%.  These are stellar results, and we thank their CEOs.

We’ve  come  close  to  eliminating  our  direct  foreign-exchange  position,  from  which  we  realized 
about  $186  million  in  pre-tax  profits  in  2006  (earnings  that  were  included  in  the  Finance  and  Financial 
Products table shown earlier).  That brought our total gain since inception of this position in 2002 to $2.2 
billion.  Here’s a breakdown by currency:

We’ve made large indirect currency profits as well, though I’ve never tallied the precise amount.  
For  example,  in  2002-2003  we  spent  about  $82  million  buying  –  of  all  things  –  Enron  bonds,  some  of 
which were denominated in Euros.  Already we’ve received distributions of $179 million from these bonds, 
and our remaining stake is worth $173 million.  That means our overall gain is $270 million, part of which 
came from the appreciation of the Euro that took place after our bond purchase. 

When  we  first  began  making  foreign  exchange  purchases,  interest-rate  differentials  between  the 
U.S.  and  most  foreign  countries  favored  a  direct  currency  position.    But  that  spread  turned  negative  in 
2005.    We  therefore  looked  for  other  ways  to  gain  foreign-currency  exposure,  such  as  the  ownership  of 
foreign equities or of U.S. stocks with major earnings abroad.  The currency factor, we should emphasize, 
is not dominant in our selection of equities, but is merely one of many considerations. 

As our U.S. trade problems worsen, the probability that the dollar will weaken over time continues 
to be high.  I fervently believe in real trade – the more the better for both us and the world.  We had about 
$1.44 trillion of this honest-to-God trade in 2006.  But the U.S. also had $.76 trillion of pseudo-trade last 
year – imports for which we exchanged no goods or services.  (Ponder, for a moment, how commentators 
would describe the situation if our imports were $.76 trillion – a full 6% of GDP – and we had no exports.)  
Making these purchases that weren’t reciprocated by sales, the U.S. necessarily transferred ownership of its 
assets or IOUs to the rest of the world.  Like a very wealthy but self-indulgent family, we peeled off a bit of 
what we owned in order to consume more than we produced. 

The  U.S.  can  do  a  lot  of  this  because  we  are  an  extraordinarily  rich  country  that  has  behaved 
responsibly  in  the  past.    The  world  is  therefore  willing  to  accept  our  bonds,  real  estate,  stocks  and 
businesses.  And we have a vast store of these to hand over. 

These transfers will have consequences, however.  Already the prediction I made last year about 
one  fall-out  from  our  spending  binge  has  come  true:  The  “investment  income”  account  of  our  country  – 
positive in every previous year since 1915 – turned negative in 2006.  Foreigners now earn more on their 
U.S. investments than we do on our investments abroad.  In effect, we’ve used up our bank account and 
turned  to  our  credit  card.    And,  like  everyone  who  gets  in  hock,  the  U.S.  will  now  experience  “reverse 
compounding” as we pay ever-increasing amounts of interest on interest. 

I  want  to  emphasize  that  even  though  our  course  is  unwise,  Americans  will  live  better  ten  or 
twenty years from now than they do today.  Per-capita wealth will increase.  But our citizens will also be 
forced every year to ship a significant portion of their current production abroad merely to service the cost 
of our huge debtor position.  It won’t be pleasant to work part of each day to pay for the over-consumption  

16

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
of your ancestors.  I believe that at some point in the future U.S. workers and voters will find this annual 
“tribute”  so  onerous  that  there  will  be  a  severe  political  backlash.    How  that  will  play  out  in  markets  is 
impossible to predict – but to expect a “soft landing” seems like wishful thinking. 

* * * * * * * * * * * * 

I should mention that all of the direct currency profits we have realized have come from forward 
contracts, which are derivatives, and that we have entered into other types of derivatives contracts as well.  
That may seem odd, since you know of our expensive experience in unwinding the derivatives book at Gen 
Re and also have heard me talk of the systemic problems that could result from the enormous growth in the 
use of derivatives.  Why, you may wonder, are we fooling around with such potentially toxic material? 

The answer is that derivatives, just like stocks and bonds, are sometimes wildly  mispriced.  For 
many years, accordingly, we have selectively written derivative contracts – few in number but sometimes 
for large dollar amounts.  We currently have 62 contracts outstanding.  I manage them personally, and they 
are  free  of  counterparty  credit  risk.    So  far,  these  derivative  contracts  have  worked  out  well  for  us, 
producing pre-tax profits in the hundreds of millions of dollars (above and beyond the gains I’ve itemized 
from  forward  foreign-exchange  contracts).    Though  we  will  experience  losses  from  time  to  time,  we  are 
likely to continue to earn – overall – significant profits from mispriced derivatives. 

I have told you that Berkshire has three outstanding candidates to replace me as CEO and that the 
Board knows exactly who should take over if I should die tonight.  Each of the three is much younger than 
I.  The directors believe it’s important that my successor have the prospect of a long tenure. 

* * * * * * * * * * * * 

Frankly,  we  are  not  as  well-prepared  on  the  investment  side  of  our  business.    There’s  a  history 
here: At one time, Charlie was my potential replacement for investing, and more recently Lou Simpson has 
filled  that  slot.    Lou  is  a  top-notch  investor  with  an outstanding  long-term  record of managing  GEICO’s 
equity  portfolio.    But  he  is  only  six  years  younger  than  I.    If  I  were  to  die  soon,  he  would  fill  in 
magnificently for a short period.  For the long-term, though, we need a different answer. 

At  our  October  board  meeting,  we  discussed  that  subject  fully.    And  we  emerged  with  a  plan, 

which I will carry out with the help of Charlie and Lou. 

Under  this  plan,  I  intend  to  hire  a  younger  man  or  woman  with  the  potential  to  manage  a  very 
large  portfolio,  who  we  hope  will  succeed  me  as  Berkshire’s  chief  investment  officer  when  the  need  for 
someone to do that arises.  As part of the selection process, we may in fact take on several candidates. 

Picking the right person(s) will not be an easy task.  It’s not hard, of course, to find smart people, 
among them individuals who have impressive investment records.  But there is far more to successful long-
term investing than brains and performance that has recently been good.   

Over time, markets will do extraordinary, even bizarre, things.  A single, big mistake could wipe 
out a long string of successes.  We therefore need someone genetically programmed to recognize and avoid 
serious  risks,  including  those  never  before  encountered.    Certain  perils  that  lurk  in  investment  strategies 
cannot be spotted by use of the models commonly employed today by financial institutions. 

Temperament  is  also  important.    Independent  thinking,  emotional  stability,  and  a  keen 
understanding of both human and institutional behavior is vital to long-term investment success.  I’ve seen 
a lot of very smart people who have lacked these virtues. 

Finally, we have a special problem to consider: our ability to keep the person we hire.  Being able 
to list Berkshire on a resume would materially enhance the marketability of an investment manager.  We 
will need, therefore, to be sure we can retain our choice, even though he or she could leave and make much 
more money elsewhere.

There are surely people who fit what we need, but they may be hard to identify.  In 1979, Jack 
Byrne  and I  felt  we  had  found  such  a person  in  Lou  Simpson.   We  then  made  an  arrangement  with him 
whereby  he  would  be  paid  well  for  sustained  overperformance.    Under  this  deal,  he  has  earned  large 
amounts.    Lou,  however,  could  have  left  us  long  ago  to  manage  far  greater  sums  on  more  advantageous 
terms.    If  money  alone  had  been  the  object,  that’s  exactly  what  he  would  have  done.    But  Lou  never 
considered such a move.  We need to find a younger person or two made of the same stuff.   

The good news: At 76, I feel terrific and, according to all measurable indicators, am in excellent 

health.  It’s amazing what Cherry Coke and hamburgers will do for a fellow.

Some Changes on Berkshire’s Board 

The composition of our board will change in two ways this spring.  One change will involve the 
Chace  family,  which  has  been  connected  to  Berkshire  and  its  predecessor  companies  for  more  than  a 
century.    In  1929,  the  first  Malcolm  G.  Chace  played  an  important  role  in  merging  four  New  England 
textile  operations  into  Berkshire  Fine  Spinning  Associates.    That  company  merged  with  Hathaway 
Manufacturing in 1955 to form Berkshire Hathaway, and Malcolm G. Chace, Jr. became its chairman. 

Early  in  1965,  Malcolm  arranged  for  Buffett  Partnership  Ltd.  to  buy  a  key  block  of  Berkshire 
shares and welcomed us as the new controlling shareholder of the company.  Malcolm continued as non-
executive chairman until 1969.  He was both a wonderful gentleman and helpful partner. 

That description also fits his son, Malcolm “Kim” Chace, who succeeded his father on Berkshire’s 
board  in  1992.    But  last  year  Kim,  now  actively  and  successfully  running  a  community  bank  that  he 
founded in 1996, suggested that we find a younger person to replace him on our board.  We have done so, 
and Kim will step down as a director at the annual meeting.  I owe much to the Chaces and wish to thank 
Kim for his many years of service to Berkshire. 

In  selecting  a  new  director,  we  were  guided  by  our  long-standing  criteria,  which  are  that  board 
members be owner-oriented, business-savvy, interested and truly independent.  I say “truly” because many 
directors who are now deemed independent by various authorities and observers are far from that, relying 
heavily as they do on directors’ fees to maintain their standard of living.  These payments, which come in 
many  forms,  often  range  between  $150,000  and  $250,000  annually,  compensation  that  may  approach  or 
even  exceed  all  other  income  of  the  “independent”  director.    And  –  surprise,  surprise  –  director 
compensation  has  soared  in  recent  years,  pushed  up  by  recommendations  from  corporate  America’s 
favorite  consultant,  Ratchet,  Ratchet  and  Bingo.    (The  name  may  be  phony,  but  the  action  it  conveys  is 
not.) 

Charlie and I believe our four criteria are essential if directors are to do their job – which, by law, 
is  to  faithfully  represent  owners.    Yet  these  criteria  are  usually  ignored.    Instead,  consultants  and  CEOs 
seeking board candidates will often say, “We’re looking for a woman,” or “a Hispanic,” or “someone from 
abroad,” or what have you.  It sometimes sounds as if the mission is to stock Noah’s ark.  Over the years 
I’ve been queried many times about potential directors and have yet to hear anyone ask, “Does he think like 
an intelligent owner?”   

The  questions  I  instead  get  would  sound  ridiculous  to  someone  seeking  candidates  for,  say,  a 
football team, or an arbitration panel or a military command.  In those cases, the selectors would look for 
people who had the specific talents and attitudes that were required for a specialized job.  At Berkshire, we 
are in the specialized activity of running a business well, and therefore we seek business judgment. 

That’s exactly what we’ve found in Susan Decker, CFO of Yahoo!, who will join our board at the 
annual meeting.  We are lucky to have her: She scores very high on our four criteria and additionally, at 44, 
is young – an attribute, as you may have noticed, that your Chairman has long lacked.  We will seek more 
young directors in the future, but never by slighting the four qualities that we insist upon.

This and That 

Berkshire will pay about $4.4 billion in federal income tax on its 2006 earnings.  In its last fiscal 
year the U.S. Government spent $2.6 trillion, or about $7 billion per day.  Thus, for more than half of one 
day, Berkshire picked up the tab for all federal expenditures, ranging from Social Security and Medicare 
payments to the cost of our armed services.  Had there been only 600 taxpayers like Berkshire, no one else 
in America would have needed to pay any federal income or payroll taxes. 

Our federal return last year, we should add, ran to 9,386 pages.  To handle this filing, state and 
foreign  tax  returns,  a  myriad  of  SEC  requirements,  and  all  of  the  other  matters  involved  in  running 
Berkshire, we have gone all the way up to 19 employees at World Headquarters. 

* * * * * * * * * * * * 

This crew occupies 9,708 square feet of space, and Charlie – at World Headquarters West in Los 
Angeles  –  uses  another  655  square  feet.    Our  home-office  payroll,  including  benefits  and  counting  both 
locations, totaled $3,531,978 last year.  We’re careful when spending your money. 

Corporate  bigwigs  often  complain  about  government  spending,  criticizing  bureaucrats  who  they 
say  spend  taxpayers’  money  differently  from  how  they  would  if  it  were  their  own.    But  sometimes  the 
financial  behavior  of  executives  will  also  vary  based  on  whose  wallet  is  getting  depleted.    Here’s  an 
illustrative tale from my days at Salomon.  In the 1980s the company had a barber, Jimmy by name, who 
came in weekly to give free haircuts to the top brass.  A manicurist was also on tap.  Then, because of a 
cost-cutting  drive,  patrons  were  told  to  pay  their  own  way.    One  top  executive  (not  the  CEO)  who  had 
previously visited Jimmy weekly went immediately to a once-every-three-weeks schedule. 

* * * * * * * * * * * * 

Every  now  and  then  Charlie  and  I  catch  on  early  to  a  tide-like  trend,  one  brimming  over  with 
commercial  promise.    For  example,  though  American  Airlines  (with  its  “miles”)  and  American  Express 
(with credit card points) are credited as being trailblazers in granting customers “rewards,” Charlie and I 
were far ahead of them in spotting the appeal of this powerful idea.  Excited by our insight, the two of us 
jumped into the reward business way back in 1970 by buying control of a trading stamp operation, Blue 
Chip Stamps.  In that year, Blue Chip had sales of $126 million, and its stamps papered California. 

In 1970, indeed, about 60 billion of our stamps were licked by savers, pasted into books, and taken 
to Blue Chip redemption stores.  Our catalog of rewards was 116 pages thick and chock full of tantalizing 
items.  When I was told that even certain brothels and mortuaries gave stamps to their patrons, I felt I had 
finally found a sure thing. 

Well, not quite.  From the day Charlie and I stepped into the Blue Chip picture, the business went 
straight downhill.  By 1980, sales had fallen to $19.4 million.  And, by 1990, sales were bumping along at 
$1.5 million.  No quitter, I redoubled my managerial efforts. 

Sales then fell another 98%.  Last year, in Berkshire’s $98 billion of revenues, all of $25,920 (no 

zeros omitted) came from Blue Chip.  Ever hopeful, Charlie and I soldier on. 

* * * * * * * * * * * * 

I mentioned last year that in my service on 19 corporate boards (not counting Berkshire or other 
controlled companies), I have been the Typhoid Mary of compensation committees.  At only one company 
was I assigned to comp committee duty, and then I was promptly outvoted on the most crucial decision that 
we faced.  My ostracism has been peculiar, considering that I certainly haven’t lacked experience in setting 
CEO  pay.    At Berkshire,  after  all,  I  am  a  one-man  compensation  committee  who determines  the  salaries 
and incentives for the CEOs of around 40 significant operating businesses. 

19

 
 
 
 
 
 
 
 
 
 
 
 
 
How  much  time  does  this  aspect  of  my  job  take?    Virtually  none.    How  many  CEOs  have 

voluntarily left us for other jobs in our 42-year history?  Precisely none. 

Berkshire  employs  many  different  incentive  arrangements,  with  their  terms  depending  on  such 
elements as the economic potential or capital intensity of a CEO’s business.  Whatever the compensation 
arrangement, though, I try to keep it both simple and fair. 

When we use incentives – and these can be large – they are always tied to the operating results for 
which  a  given  CEO  has  authority.    We  issue  no  lottery  tickets  that  carry  payoffs  unrelated  to  business 
performance.  If a CEO bats .300, he gets paid for being a .300 hitter, even if circumstances outside of his 
control cause Berkshire to perform poorly.  And if he bats .150, he doesn’t get a payoff just because the 
successes of others have enabled Berkshire to prosper mightily.  An example:  We now own $61 billion of 
equities at Berkshire, whose value can easily rise or fall by 10% in a given year.  Why in the world should 
the pay of our operating executives be affected by such $6 billion swings, however important the gain or 
loss may be for shareholders? 

You’ve  read  loads  about  CEOs  who  have  received  astronomical  compensation  for  mediocre 
results.  Much less well-advertised is the fact that America’s CEOs also generally live the good life.  Many, 
it should be emphasized, are exceptionally able, and almost all work far more than 40 hours a week.  But 
they  are  usually  treated  like  royalty  in  the  process.    (And  we’re  certainly  going  to  keep  it  that  way  at 
Berkshire.  Though Charlie still favors sackcloth and ashes, I prefer to be spoiled rotten.  Berkshire owns 
The Pampered Chef; our wonderful office group has made me The Pampered Chief.) 

CEO perks at one company are quickly copied elsewhere.  “All the other kids have one” may seem 
a  thought  too  juvenile  to  use  as  a  rationale  in  the  boardroom.    But  consultants  employ  precisely  this 
argument, phrased more elegantly of course, when they make recommendations to comp committees. 

Irrational  and  excessive  comp  practices  will  not  be  materially  changed  by  disclosure  or  by 
“independent”  comp  committee  members.    Indeed,  I  think  it’s  likely  that  the  reason  I  was  rejected  for 
service on so many comp committees was that I was regarded as too independent.  Compensation reform 
will only occur if the largest institutional shareholders – it would only take a few – demand a fresh look at 
the whole system.  The consultants’ present drill of deftly selecting “peer” companies to compare with their 
clients will only perpetuate present excesses. 

* * * * * * * * * * * * 

Last  year  I  arranged  for  the  bulk  of  my  Berkshire holdings  to  go  to  five  charitable  foundations, 
thus  carrying  out  part  of  my  lifelong  plan  to  eventually  use  all  of  my  shares  for  philanthropic  purposes.  
Details  of  the  commitments  I  made,  as  well  as  the  rationale  for  them,  are  posted  on  our  website, 
www.berkshirehathaway.com.  Taxes, I should note, had nothing to do with my decision or its timing.  My 
federal and state income taxes in 2006 were exactly what they would have been had I not made my first 
contributions last summer, and the same point will apply to my 2007 contributions. 

In my will I’ve stipulated that the proceeds from all Berkshire shares I still own at death are to be 
used  for  philanthropic  purposes  within  ten  years  after  my  estate  is  closed.    Because  my  affairs  are  not 
complicated, it should take three years at most for this closing to occur.  Adding this 13-year period to my 
expected lifespan of about 12 years (though, naturally, I’m aiming for more) means that proceeds from all 
of my Berkshire shares will likely be distributed for societal purposes over the next 25 years or so. 

I’ve set this schedule because I want the money to be spent relatively promptly by people I know 
to  be  capable,  vigorous  and  motivated.    These  managerial  attributes  sometimes  wane  as  institutions  – 
particularly those that are exempt from market forces – age.  Today, there are terrific people in charge at 
the  five  foundations.    So  at  my  death,  why  should  they  not  move  with  dispatch  to  judiciously  spend  the 
money that remains? 

20

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Those people favoring perpetual foundations argue that in the future there will most certainly be 
large and important societal problems that philanthropy will need to address.  I agree.  But there will then 
also be many super-rich individuals and families whose wealth will exceed that of today’s Americans and 
to  whom  philanthropic  organizations  can  make  their  case  for  funding.    These  funders  can  then  judge 
firsthand which operations have both the vitality and the focus to best address the major societal problems 
that then exist.  In this way, a market test of ideas and effectiveness can be applied.  Some organizations 
will  deserve  major  support  while  others  will  have  outlived  their  usefulness.    Even  if  the  people  above 
ground  make  their  decisions  imperfectly,  they  should  be  able  to  allocate  funds  more  rationally  than  a 
decedent six feet under will have ordained decades earlier.  Wills, of course, can always be rewritten, but 
it’s very unlikely that my thinking will change in a material way. 

A few shareholders have expressed concern that sales of Berkshire by the foundations receiving 
shares  will  depress  the  stock.    These  fears  are  unwarranted.    The  annual  trading  volume  of  many  stocks 
exceeds 100% of the outstanding shares, but nevertheless these stocks usually sell at prices approximating 
their intrinsic value.  Berkshire also tends to sell at an appropriate price, but with annual volume that is only 
15%  of  shares  outstanding.    At  most,  sales  by  the  foundations  receiving  my  shares  will  add  three 
percentage points to annual trading volume, which will still leave Berkshire with a turnover ratio that is the 
lowest around. 

Overall, Berkshire’s business performance will determine the price of our stock, and most of the 
time it will sell in a zone of reasonableness.  It’s important that the foundations receive appropriate prices 
as they periodically sell Berkshire shares, but it’s also important that incoming shareholders don’t overpay.  
(See economic principle 14 on page 77.)  By both our policies and shareholder communications, Charlie 
and I will do our best to ensure that Berkshire sells at neither a large discount nor large premium to intrinsic 
value. 

The  existence  of  foundation  ownership  will  in  no  way  influence  our  board’s  decisions  about 
dividends, repurchases, or the issuance of shares.  We will follow exactly the same rule that has guided us 
in the past: What action will be likely to deliver the best result for shareholders over time? 

In  last  year’s  report  I  allegorically  described  the  Gotrocks  family  –  a  clan  that  owned  all  of 
America’s businesses and that counterproductively attempted to increase its investment returns by paying 
ever-greater  commissions  and  fees  to  “helpers.”    Sad  to  say,  the  “family”  continued  its  self-destructive 
ways in 2006. 

* * * * * * * * * * * * * 

In part the family persists in this folly because it harbors unrealistic expectations about obtainable 
returns.  Sometimes these delusions are self-serving.  For example, private pension plans can temporarily 
overstate  their  earnings,  and  public  pension  plans  can  defer  the  need  for  increased  taxes,  by  using 
investment  assumptions  that  are  likely  to  be  out  of  reach.    Actuaries  and  auditors  go  along  with  these 
tactics, and it can be decades before the chickens come home to roost (at which point the CEO or public 
official who misled the world is apt to be gone). 

Meanwhile, Wall Street’s Pied Pipers of Performance will have encouraged the futile hopes of the 
family.  The  hapless  Gotrocks  will  be  assured  that  they  all  can  achieve  above-average  investment 
performance – but only by paying ever-higher fees.  Call this promise the adult version of Lake Woebegon. 

In 2006, promises and fees hit new highs.  A flood of money went from institutional investors to 
the 2-and-20 crowd.  For those innocent of this arrangement, let me explain: It’s a lopsided system whereby 
2% of your principal is paid each year to the manager even if he accomplishes nothing – or, for that matter, 
loses you a bundle – and, additionally, 20% of your profit is paid to him if he succeeds, even if his success 
is due simply to a rising tide.  For example, a manager who achieves a gross return of 10% in a year will 
keep  3.6  percentage points –  two  points  off  the  top plus 20% of  the residual 8 points –  leaving  only  6.4 
percentage  points  for  his  investors.    On  a  $3  billion  fund,  this  6.4%  net  “performance”  will  deliver  the 
manager a cool $108 million.  He will receive this bonanza even though an index fund might have returned 
15% to investors in the same period and charged them only a token fee. 

21

 
 
 
 
 
 
 
 
 
 
 
 
The inexorable math of this grotesque arrangement is certain to make the Gotrocks family poorer 
over  time  than  it  would  have  been  had  it  never  heard  of  these  “hyper-helpers.”    Even  so,  the  2-and-20 
action spreads.  Its effects bring to mind the old adage: When someone with experience proposes a deal to 
someone with money, too often the fellow with money  ends up with the experience, and the fellow with 
experience ends up with the money. 

* * * * * * * * * * * * 

Let me end this section by telling you about one of the good guys of Wall Street, my long-time 
friend  Walter  Schloss,  who  last  year  turned  90.    From  1956  to  2002,  Walter  managed  a  remarkably 
successful investment partnership, from which he took not a dime unless his investors made money.  My 
admiration for Walter, it should be noted, is not based on hindsight.  A full fifty years ago, Walter was my 
sole recommendation to a St. Louis family who wanted an honest and able investment manager. 

Walter  did  not  go  to  business  school,  or  for  that  matter,  college.    His  office  contained  one  file 
cabinet  in  1956;  the  number  mushroomed  to  four  by  2002.    Walter  worked  without  a  secretary,  clerk  or 
bookkeeper, his only associate being his son, Edwin, a graduate of the North Carolina School of the Arts.  
Walter and Edwin never came within a mile of inside information.  Indeed, they used “outside” information 
only  sparingly,  generally  selecting  securities  by  certain  simple  statistical  methods  Walter  learned  while 
working for Ben Graham.  When Walter and Edwin were asked in 1989 by Outstanding Investors Digest, 
“How would you summarize your approach?” Edwin replied, “We try to buy stocks cheap.”  So much for 
Modern Portfolio Theory, technical analysis, macroeconomic thoughts and complex algorithms. 

Following  a  strategy  that  involved  no  real  risk  –  defined  as  permanent  loss  of  capital  –  Walter 
produced  results  over  his  47  partnership  years  that  dramatically  surpassed  those  of  the  S&P  500.    It’s 
particularly  noteworthy  that  he  built  this  record  by  investing  in  about  1,000  securities,  mostly  of  a 
lackluster type.  A few big winners did not account for his success.  It’s safe to say that had millions of 
investment  managers  made  trades  by  a)  drawing  stock  names  from  a  hat;  b)  purchasing  these  stocks  in 
comparable  amounts  when  Walter  made  a  purchase;  and  then  c)  selling  when  Walter  sold  his  pick,  the 
luckiest of them would not have come close to equaling his record.  There is simply no possibility that what 
Walter achieved over 47 years was due to chance. 

I  first  publicly  discussed  Walter’s  remarkable  record  in  1984.    At  that  time  “efficient  market 
theory” (EMT) was the centerpiece of investment instruction at most major business schools.  This theory, 
as  then  most  commonly  taught,  held  that  the  price  of  any  stock  at  any  moment  is  not  demonstrably 
mispriced, which means that no investor can be expected to overperform the stock market averages using 
only publicly-available information (though some will do so by luck).  When I talked about Walter 23 years 
ago, his record forcefully contradicted this dogma. 

And what did members of the academic community do when they were exposed to this new and 
important  evidence?    Unfortunately,  they  reacted  in  all-too-human  fashion:  Rather  than  opening  their 
minds, they closed their eyes.  To my knowledge no business school teaching EMT made any attempt to 
study Walter’s performance and what it meant for the school’s cherished theory.    

Instead,  the  faculties  of  the  schools  went  merrily  on  their  way  presenting  EMT  as  having  the 
certainty  of  scripture.    Typically,  a  finance  instructor  who  had  the  nerve  to  question  EMT  had  about  as 
much chance of major promotion as Galileo had of being named Pope. 

Tens of thousands of students were therefore sent out into life believing that on every day the price 
of  every  stock  was  “right”  (or,  more  accurately,  not  demonstrably  wrong)  and  that  attempts  to  evaluate 
businesses – that is, stocks – were useless.  Walter meanwhile went on overperforming, his job made easier 
by  the  misguided  instructions  that  had  been  given  to  those  young  minds.    After  all,  if  you  are  in  the 
shipping business, it’s helpful to have all of your potential competitors be taught that the earth is flat. 

Maybe it was a good thing for his investors that Walter didn’t go to college.

The Annual Meeting 

Our meeting this year will be held on Saturday, May 5th.   As always, the doors will open at the 
Qwest Center at 7 a.m., and a new Berkshire movie will be shown at 8:30.  At 9:30 we will go directly to 
the question-and-answer period, which (with a break for lunch at the Qwest’s stands) will last until 3:00.  
Then, after a short recess, Charlie and I will convene the annual meeting at 3:15.  If you decide to leave 
during the day’s question periods, please do so while Charlie is talking. 

The  best  reason  to  exit,  of  course  is  to  shop.    We  will  help  you  do  that  by  filling  the  194,300 
square foot hall that adjoins the meeting area with the products of Berkshire subsidiaries.  Last year, the 
24,000 people who came to the meeting did their part, and almost every location racked up record sales.  
But records are made to be broken, and I know you can do better. 

This  year  we  will  again  showcase  a  Clayton  home  (featuring  Acme  brick,  Shaw  carpet,  Johns 
Manville insulation, MiTek fasteners, Carefree awnings and NFM furniture).  You will find that the home, 
priced at $139,900, delivers excellent value.  Last year, a helper at the Qwest bought one of two homes on 
display  well  before  we  opened  the  doors  to  shareholders.    Flanking  the  Clayton  home  on  the  exhibition 
floor this year will be an RV and pontoon boat from Forest River. 

GEICO will have a booth staffed by a number of its top counselors from around the country, all of 
them  ready  to supply  you with  auto  insurance quotes.    In  most  cases,  GEICO  will  be able  to give  you  a 
special shareholder discount (usually 8%).  This special offer is permitted by 45 of the 50 jurisdictions in 
which we operate.  (One supplemental point: The discount is not additive if you qualify for another, such as 
that given certain groups.)  Bring the details of your existing insurance and check out whether we can save 
you money.  For at least 50% of you, I believe we can.  And while you’re at it, sign up for the new GEICO 
credit card.  It’s the one I now use (sparingly, of course). 

On Saturday, at the Omaha airport, we will have the usual array of aircraft from NetJets available 
for your inspection.  Stop by the NetJets booth at the Qwest to learn about viewing these planes.  Come to 
Omaha by bus; leave in your new plane.  And take all the hair gel that you wish on board with you. 

In the Bookworm’s corner of our bazaar, there will be about 25 books and DVDs – all discounted 
– led again by Poor Charlie’s Almanack.  (One hapless soul last year asked Charlie what he should do if he 
didn’t enjoy the book.  Back came a Mungerism: “No problem – just give it to someone more intelligent.”)  
We’ve added a few titles this year.  Among them are Seeking Wisdom: From Darwin to Munger by Peter 
Bevelin,  a  long-time  Swedish  shareholder  of  Berkshire,  and  Fred  Schwed’s  classic,  Where  are  the 
Customers’ Yachts?  This book was first published in 1940 and is now in its 4th edition.  The funniest book 
ever written about investing, it lightly delivers many truly important messages on the subject. 

An attachment to the proxy material that is enclosed with this report explains how you can obtain 
the  credential  you  will  need  for  admission  to  the  meeting  and  other  events.    As  for  plane,  hotel  and  car 
reservations, we have again signed up American Express (800-799-6634) to give you special help.  Carol 
Pedersen,  who  handles  these  matters,  does  a  terrific  job  for  us  each  year,  and  I  thank  her  for  it.    Hotel 
rooms can be hard to find, but work with Carol and you will get one. 

At Nebraska Furniture Mart, located on a 77-acre site on 72nd Street between Dodge and Pacific, 
we will again be having “Berkshire Weekend” discount pricing.  We initiated this special event at NFM ten 
years ago, and sales during the “Weekend” grew from $5.3 million in 1997 to $30 million in 2006.  I get 
goose bumps just thinking about this volume. 

To obtain the Berkshire discount, you must make your purchases between Thursday, May 3rd and 
Monday,  May  7th  inclusive,  and  also  present  your  meeting  credential.    The  period’s  special  pricing  will 
even apply to the products of several prestigious manufacturers that normally have ironclad rules against 
discounting  but  which,  in  the  spirit  of  our  shareholder  weekend,  have  made  an  exception  for  you.    We 
appreciate their cooperation.  NFM is open from 10 a.m. to 9 p.m. Monday through Saturday, and 10 a.m.  

23

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
to 6 p.m. on Sunday.  On Saturday this year, from 5:30 p.m. to 8 p.m., NFM is having a special shareholder 
picnic featuring chicken and beef tacos (and hamburgers for traditionalists like me). 

At a remodeled and expanded Borsheim’s, we will again have two shareholder-only events.  The 
first will be a cocktail reception from 6 p.m. to 10 p.m. on Friday, May 4th.  The second, the main gala, will 
be held on Sunday, May 6th, from 9 a.m. to 4 p.m.  On Saturday, we will be open until 6 p.m. 

We  will  have  huge  crowds  at  Borsheim’s  throughout  the  weekend.    For  your  convenience, 
therefore,  shareholder  prices  will  be  available  from  Monday,  April  30th  through  Saturday,  May  12th.  
During  that  period,  please  identify  yourself  as  a  shareholder  by  presenting  your  meeting  credentials  or  a 
brokerage statement that shows you are a Berkshire holder. 

On  Sunday,  in  a  tent  outside  of  Borsheim’s,  a  blindfolded  Patrick  Wolff,  twice  U.S.  chess 
champion, will take on all comers – who will have their eyes wide open – in groups of six.  Last year I 
carried  on  a  conversation  with  Patrick  while  he  played  in  this  manner.    Nearby,  Norman  Beck,  a 
remarkable magician from Dallas, will bewilder onlookers.  Additionally, we will have Bob Hamman and 
Sharon  Osberg,  two  of  the  world’s  top  bridge  experts,  available  to  play  bridge  with  our  shareholders  on 
Sunday afternoon. 

To  add  to  the  Sunday  fun  at  Borsheim’s,  Ariel  Hsing  will  play  table  tennis  (ping-pong  to  the 
uninitiated) from 1 p.m. to 4 p.m. against anyone brave enough to take her on.  Ariel, though only 11, is 
ranked number one among girls under 16 in the U.S. (and number 1 among both boys and girls under 12).  
The week I turned 75 I played Ariel, then 9 and barely tall enough to see across the table, thinking I would 
take it easy on her so as not to crush her young spirit.  Instead she crushed me.  I’ve since devised a plan 
that will give me a chance against her.  At 1 p.m. on Sunday, I will initiate play with a 2-point game against 
Ariel.    If  I  somehow  win  the  first  point,  I  will  then  feign  injury  and  claim  victory.    After  this  strenuous 
encounter wears Ariel down, our shareholders can then try their luck against her. 

Gorat’s will again be open exclusively for Berkshire shareholders on Sunday, May 6th, and will be 
serving from 4 p.m. until 10 p.m.  Please remember that to come to Gorat’s on that day, you must have a 
reservation.  To make one, call 402-551-3733 on April 1st (but not before).   

In  the  2006-2007  school  year,  35  university  classes,  including  one  from  IBMEC  in  Brazil,  will 
come to Omaha for sessions with me.  I take almost all – in aggregate, more than 2,000 students – to lunch 
at Gorat’s.  And they love it.  To learn why, come join us on Sunday. 

We will again have a reception at 4 p.m. on Saturday afternoon for shareholders who have come 
from outside of North America.  Every year our meeting draws many people from around the globe, and 
Charlie  and  I  want  to  be  sure  we  personally  greet  those  who  have  come  so  far.    Last  year  we  enjoyed 
meeting  more  than 400 of  you  from  many  dozens of  countries.   Any  shareholder who  comes  from  other 
than the U.S. or Canada will be given a special credential and instructions for attending this function. 

* * * * * * * * * * * * 

Charlie and I are extraordinarily lucky.  We were born in America; had terrific parents who saw 
that we got good educations; have enjoyed wonderful families and great health; and came equipped with a 
“business”  gene  that  allows  us  to  prosper  in  a  manner  hugely  disproportionate  to  other  people  who 
contribute as much or more to our society’s well-being.  Moreover, we have long had jobs that we love, in 
which we are helped every day in countless ways by talented and cheerful associates.  No wonder we tap-
dance  to  work.    But  nothing  is  more  fun  for  us  than  getting  together  with  our  shareholder-partners  at 
Berkshire’s annual meeting.  So join us on May 5th at the Qwest for our annual Woodstock for Capitalists.  
We’ll see you there.

We are eager to hear from principals or their representatives about businesses that meet all of the following criteria: 

BERKSHIRE HATHAWAY INC. 

ACQUISITION CRITERIA 

Large purchases (at least $75 million of pre-tax earnings unless the business will fit into one of our existing units), 
Demonstrated consistent earning power (future projections are of no interest to us, nor are “turnaround” situations), 
Businesses earning good returns on equity while employing little or no debt, 

(1) 
(2) 
(3) 
(4)  Management in place (we can’t supply it), 
(5) 
(6) 

Simple businesses (if there’s lots of technology, we won’t understand it), 
An offering price (we don’t want to waste our time or that of the seller by talking, even preliminarily, 
about a transaction when price is unknown). 

The larger the company, the greater will be our interest: We would like to make an acquisition in the $5-20 billion range. We are not 

interested, however, in receiving suggestions about purchases we might make in the general stock market. 

We will not engage in unfriendly takeovers. We can promise complete confidentiality and a very fast answer — customarily within five 
minutes — as to whether we’re interested. We prefer to buy for cash, but will consider issuing stock when we receive as much in intrinsic 
business value as we give.  We don’t participate in auctions. 

Charlie and I frequently get approached about acquisitions that don’t come close to meeting our tests: We’ve found that if you advertise 
an interest in buying collies, a lot of people will call hoping to sell you their cocker spaniels. A line from a country song expresses our 
feeling about new ventures, turnarounds, or auction-like sales: “When the phone don’t ring, you’ll know it’s me.” 

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the Board of Directors and Shareholders of 
Berkshire Hathaway Inc. 

We  have  audited  the  accompanying  consolidated  balance  sheets  of  Berkshire  Hathaway  Inc.  and  subsidiaries  (the  “Company”)  as  of 
December  31,  2006  and  2005,  and  the  related  consolidated  statements  of  earnings,  cash  flows  and  changes  in  shareholders’  equity  and 
comprehensive income for each of the three years in the period ended December 31, 2006.  These financial statements are the responsibility 
of the Company’s management.  Our responsibility is to express an opinion on these financial statements based on our audits. 

We  conducted  our  audits  in accordance  with  the  standards  of  the  Public  Company  Accounting Oversight  Board  (United  States).    Those 
standards  require  that  we  plan  and  perform  the  audit  to  obtain  reasonable  assurance  about  whether  the  financial  statements  are  free  of 
material  misstatement.    An  audit  includes  examining,  on  a  test  basis,  evidence  supporting  the  amounts  and  disclosures  in  the  financial 
statements.    An  audit  also  includes  assessing  the  accounting  principles  used  and  significant  estimates  made  by  management,  as  well  as 
evaluating the overall financial statement presentation.  We believe that our audits provide a reasonable basis for our opinion. 

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of Berkshire Hathaway 
Inc. and subsidiaries as of December 31, 2006 and 2005, and the results of their operations and their cash flows for each of the three years 
in the period ended December 31, 2006, in conformity with accounting principles generally accepted in the United States of America. 

As  discussed  in  Note  18  to  the  consolidated  financial  statements,  as  of  December  31,  2006,  the  Company  changed  its  accounting  for 
pensions and other postretirement benefits to conform to Statement of Financial Accounting Standards No. 158, Employers’ Accounting for 
Defined Benefit Pension and Other Postretirement Plans, an amendment of FASB Statements No. 87, 88, 106, and 132(R). 

We  have  also  audited,  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board  (United  States),  the 
effectiveness  of  the  Company’s  internal  control  over  financial  reporting  as  of  December  31,  2006,  based  on  the  criteria  established  in 
Internal  Control—Integrated  Framework  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission  and  our 
report  dated    February  28,  2007  expressed  an  unqualified  opinion  on  management’s  assessment  of  the  effectiveness  of  the  Company’s 
internal control over financial reporting and an unqualified opinion on the effectiveness of the Company’s internal control over financial 
reporting.

FORWARD-LOOKING STATEMENTS 

Investors  are  cautioned  that  certain  statements  contained  in  this  document,  as  well  as  some  statements  by  the  Company  in 
periodic  press  releases  and  some  oral  statements  of  Company  officials  during  presentations  about  the  Company,  are  “forward-looking” 
statements within the meaning of the Private Securities Litigation Reform Act of 1995 (the “Act”).  Forward-looking statements include 
statements  which  are  predictive  in  nature,  which  depend  upon  or  refer  to  future  events  or  conditions,  which  include  words  such  as 
“expects,” “anticipates,” “intends,” “plans,” “believes,” “estimates,” or similar expressions.  In addition, any statements concerning future 
financial performance (including future revenues, earnings or growth rates), ongoing business strategies or prospects, and possible future 
Company actions, which may be provided by management are also forward-looking statements as defined by the Act.  Forward-looking 
statements are based on current expectations and projections about future events and are subject to risks, uncertainties, and assumptions 
about  the  Company,  economic  and  market  factors  and  the  industries  in  which  the  Company  does  business,  among  other  things.    These 
statements are not guaranties of future performance and the Company has no specific intention to update these statements. 

Actual events and results may differ materially from those expressed or forecasted in forward-looking statements due to a number 
of factors.  The principal important risk factors that could cause the Company’s actual performance and future events and actions to differ 
materially from such forward-looking statements, include, but are not limited to, changes in market prices of Berkshire’s significant equity 
investees,  the  occurrence  of  one  or  more  catastrophic  events,  such  as  an  earthquake,  hurricane  or  an  act  of  terrorism  that  causes  losses 
insured by Berkshire’s insurance subsidiaries, changes in insurance laws or regulations, changes in Federal income tax laws, and changes in 
general economic and market factors that affect the prices of securities or the industries in which Berkshire and its affiliates do business.

and Subsidiaries 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
December 31, 2006 

(1) 

Significant accounting policies and practices 

(a) 

Nature of operations and basis of consolidation 
Berkshire Hathaway Inc. (“Berkshire” or “Company”) is a holding company owning subsidiaries engaged in a number 
of  diverse  business  activities,  including  property  and  casualty  insurance  and  reinsurance,  utilities  and  energy, 
finance,  manufacturing,  retailing  and  services.    Further  information  regarding  these  businesses  and  Berkshire’s 
reportable  business  segments  is  contained  in  Note  20.    Berkshire  consummated  a  number  of  business  acquisitions 
over the past three years which are discussed in Note 3. 

(b) 

(c) 

(d) 

The accompanying Consolidated Financial Statements include the accounts of Berkshire consolidated with the accounts 
of  all  of  its  subsidiaries  and  affiliates  in  which  Berkshire  holds  a  controlling  financial  interest  as  of  the  financial 
statement  date.    Normally  a  controlling  financial  interest  reflects  ownership  of  a  majority  of  the  voting  interests. 
Other  factors  considered  in  determining  whether  a  controlling  financial  interest  is  held  include whether  Berkshire 
possesses  the  authority  to  purchase  or  sell  assets  or  make  other  operating  decisions  that  significantly  affect  the 
entity’s  results  of  operations  and  whether  Berkshire  bears  a  majority  of  the  financial  risks  of  the  entity. 
Intercompany  accounts  and  transactions  have  been  eliminated.  Certain  amounts  in  prior  year  presentations  have 
been reclassified to conform with the current year presentation. 

Use of estimates in preparation of financial statements 
The preparation of the Consolidated Financial Statements in conformity with generally accepted accounting principles 
(“GAAP”) requires management to make estimates and assumptions that affect the reported amount of assets and 
liabilities at the date of the financial statements and the reported amount of revenues and expenses during the period. 
In particular, estimates of unpaid losses and loss adjustment expenses and related recoverables under reinsurance for 
property  and  casualty  insurance  are  subject  to  considerable  estimation  error  due  to  the  inherent  uncertainty  in 
projecting  ultimate  claim  amounts  that  can  be  reported  and  settled  over  a  period  of  many  years.    In  addition, 
estimates  and  assumptions  associated  with  the  amortization  of  deferred  charges  reinsurance  assumed,  the 
determination  of  fair  value  of  certain  invested  assets  and  related  impairments  and  the  determination  of  goodwill 
impairments require considerable judgment by management.  Actual results may differ from the estimates used in 
preparing the Consolidated Financial Statements. 

Cash equivalents 
Cash  equivalents  consist  of  funds  invested  in  U.S.  Treasury  Bills,  money  market  accounts,  and  in  other  investments 
with  a  maturity  of  three  months  or  less  when  purchased.  Cash  and  cash  equivalents  exclude  amounts  where 
availability  is  restricted  by  loan  agreements  or  other  contractual  provisions.    Restricted  amounts  are  included  in 
other assets. 

Investments 
Berkshire’s  management  determines  the  appropriate  classifications  of  investments  in  fixed  maturity  and  equity 
securities  at  the  acquisition  date  and  re-evaluates  the  classifications  at  each  balance  sheet  date.    Berkshire’s 
investments in fixed maturity and equity securities are primarily classified as available-for-sale, except for certain 
securities held by finance businesses which are classified as held-to-maturity. 

Held-to-maturity investments are carried at amortized cost, reflecting Berkshire’s intent and ability to hold the securities 
to  maturity.   Available-for-sale  securities are  stated  at  fair  value with  net  unrealized  gains  or losses  reported  as a 
component of accumulated other comprehensive income. 

Investment  gains  and  losses  arise  when  investments  are  sold  (as  determined  on  a  specific  identification  basis)  or  are 
other-than-temporarily impaired.  If in management’s judgment a decline in the value of an investment below cost is 
other  than  temporary,  the  cost  of  the  investment  is  written  down  to  fair  value  with  a  corresponding  charge  to 
earnings.    Factors  considered  in  judging  whether  an  impairment  is  other  than  temporary  include:  the  financial 
condition, business prospects and creditworthiness of the issuer, the length of time that fair value has been less than 
cost, the relative amount of the decline, and Berkshire’s ability and intent to hold the investment until the fair value 
recovers. 

Berkshire utilizes the equity method of accounting with respect to investments where it exercises significant influence, 
but not control, over the operating and financial policies of the investee.  A voting interest of at least 20% and no 
greater  than  50%  is  normally  a  prerequisite  for  utilizing  the  equity  method.    However,  Berkshire  may  apply  the 
equity method with less than 20% voting interests based upon the facts and circumstances including representation 
on the investee’s Board of Directors, contractual veto or  approval rights, participation in policy making processes 
and  the  existence  or  absence  of  other  significant  owners.  Berkshire  applies  the  equity  method  to  investments  in 
common  stock  and  other  investments  when  such  other  investments  possess  substantially  identical  subordinated 
interests to common stock.

Notes to Consolidated Financial Statements (Continued) 
(1)  Significant accounting policies and practices (Continued) 

(d) 

(e) 

Investments (Continued) 
In applying the equity method, investments are recorded at cost and subsequently increased or decreased by Berkshire’s 
proportionate  share  of  the  net  earnings  or  losses  of  the  investee.   Berkshire  also  records  its  proportionate  share of 
other comprehensive income items of the investee as a component of its comprehensive income. Dividends or other 
equity distributions are recorded as a reduction of the investment.  In the event that net losses of the investee have 
reduced  the  equity  method  investment  to  zero,  additional  net  losses  may  be  recorded  if  other  investments  in  the 
investee are at-risk, even if Berkshire has not committed to provide financial support to the investee.  Berkshire bases 
such additional equity method loss amounts, if any, on the change in its claim on the investee’s book value. 

Loans and finance receivables 
Loans  and  finance  receivables  consist  of  commercial  and  consumer  loans  originated  or  purchased  by  Berkshire’s 
finance and financial products businesses.  Loans and finance receivables are stated at amortized cost less allowances 
for  uncollectible  accounts  based  on  Berkshire’s  ability  and  intent  to  hold  such  loans  and  receivables  to  maturity. 
Amortized cost represents acquisition cost, plus or minus origination and commitment costs paid or fees received, 
which together with acquisition premiums or discounts are deferred and amortized as yield adjustments over the life 
of the loan. 

Allowances for estimated losses from uncollectible loans are recorded when it is probable that the counterparty will be 
unable  to  pay  all  amounts  due  according  to  the  terms  of  the  loan.    Allowances  are  provided  on  aggregations  of 
consumer  loans  with  similar  characteristics  and  terms  based  upon  historical  loss  and  recovery  experience, 
delinquency  rates  and  current  economic  conditions.    Provisions  for  loan  losses  are  included  in  the  Consolidated 
Statements of Earnings. 

(f) 

Derivatives 
Derivative instruments include interest rate, currency, equity and credit swaps and options, interest rate caps and floors 

and futures and forward contracts. 

Berkshire  carries  derivative  contracts  at  estimated  fair  value  classified  as  assets  or  liabilities  in  the  accompanying 
Consolidated  Balance  Sheets.    Such  balances  reflect  reductions  permitted  under  master  netting  agreements  with 
counterparties.  The fair values of these instruments generally represent the present value of estimated future cash 
flows under the contracts, which are a function of current underlying interest rates, currency rates, security values, 
related  volatility,  counterparty  creditworthiness  and  duration  of  the  contracts.    Changes  in  these  factors  or  a 
combination thereof may affect the fair value of these instruments. 

The  changes  in  fair  value  of  derivative  contracts  that  do  not  qualify  as  hedging  instruments  for  financial  reporting 

purposes are included in the Consolidated Statements of Earnings as derivative gains/losses. 

Derivative contracts may provide for Berkshire or the counterparty to post collateral as security against the fair value of 
open  or  unsettled  contracts.  Cash  collateral  received  from  or  paid  to  counterparties  to  secure  derivative  contract 
assets  or  liabilities  is  included  in  liabilities  or  assets  of  finance  and  financial  products  businesses  in  the 
Consolidated  Balance  Sheets.  Securities  received  from  counterparties  as  collateral  are  not  recorded  as  assets  and 
securities  delivered  to  counterparties  as  collateral  continue  to  be  reflected  as  assets  in  the  Consolidated  Balance 
Sheets. 

Inventories 
Inventories  consist  of  manufactured  goods  and  purchased  goods  acquired  for  resale.    Manufactured  inventory  costs 
include raw materials, direct and indirect labor and factory overhead.  Inventories are stated at the lower of cost or 
market.  As of December 31, 2006, approximately 53% of the total inventory cost was determined using the last-in-
first-out (“LIFO”) method, 41% using the first-in-first-out (“FIFO”) method, with the remainder using the specific 
identification method.  With respect to inventories carried at LIFO cost, the aggregate difference in value between 
LIFO cost and cost determined under FIFO methods was $263 million and $237 million as of December 31, 2006 
and 2005, respectively. 

Property, plant and equipment 
Property, plant and equipment is recorded at cost.  The cost of major additions and betterments are capitalized, while 
replacements,  maintenance  and  repairs  that  do  not  improve  or  extend  the  useful  lives  of  the  related  assets  are 
expensed  as  incurred.    Interest  over  the  construction  period  is  capitalized  as  a  component  of  cost  of  constructed 
assets.  In addition,  the cost of constructed assets of certain domestic regulated utility and energy subsidiaries that 
are subject to SFAS No. 71, “Accounting for the Effects of Certain Types of Regulation” (“SFAS 71”) includes the 
capitalization of the estimated cost of capital in addition to interest incurred during the construction period.  Also see 
Note 1(n). 

Depreciation is provided principally on the straight-line method over estimated useful lives.  Depreciation of assets of 
certain  regulated  utility  and energy  subsidiaries  is  provided  over recovery periods  based  on  composite  asset class 
lives as mandated by regulation.

Property, plant and equipment (Continued) 
Property, plant and equipment is evaluated for impairment when events or changes in circumstances indicate that the 
carrying  value  of  the  assets  may  not  be  recoverable,  or  the  assets  meet  the  criteria  of  held  for  sale.    Upon  the 
occurrence  of  a  triggering  event,  the  asset  is  reviewed  to  assess  whether  the  estimated  undiscounted  cash  flows 
expected from the use of the asset plus residual value from the ultimate disposal exceeds the carrying value of the 
asset.  If the carrying value exceeds the estimated recoverable amounts, the asset is written down to the estimated 
discounted present value of the expected future cash flows from using the asset.  Impairment losses are reflected in 
the Consolidated Statements of Earnings, except with respect to impairments of assets of certain domestic regulated 
utility  and  energy  subsidiaries  where  losses  are  offset  by  the  establishment  of  a  regulatory  asset  to  the  extent 
recovery in future rates is probable. 

Goodwill 
Goodwill  represents  the  difference  between  purchase  cost  and  the  fair  value  of  net  assets  acquired  in  business 
acquisitions.  Goodwill is tested for impairment using a variety of methods at least annually and impairments, if any, 
are  charged  to  earnings.    Key  assumptions  used  in  the  testing  include,  but  are  not  limited  to,  the  use  of  an 
appropriate  discount  rate  and  estimated  future  cash  flows.    In  estimating  cash  flows,  the  Company  incorporates 
current market information as well as historical factors. 

Revenue recognition 
Insurance  premiums  for  prospective  property/casualty  insurance  and  reinsurance  and  health  reinsurance  policies  are 
earned  in  proportion  to  the  level  of  insurance  protection  provided.    In  most  cases,  premiums  are  recognized  as 
revenues  ratably  over  the  term  of  the  contract  with  unearned  premiums  computed  on  a  monthly  or  daily  pro  rata 
basis.  Premiums for retroactive reinsurance property/casualty policies are earned at the inception of the contracts. 
Premiums for life reinsurance contracts are earned when due. 

Premiums  earned  are  stated  net  of  amounts  ceded  to  reinsurers.    Premiums  are  estimated  with  respect  to  certain 
reinsurance  contracts  written  during  the  period  where  reports  from  ceding  companies  for  the  period  are  not 
contractually due until after the balance sheet date.  For policies containing experience rating provisions, premiums 
are based upon estimated loss experience under the contract. 

Sales revenues derive from the sales of manufactured products and goods acquired for resale.  Revenues from sales are 
recognized upon passage of title to the customer, which generally coincides with customer pickup, product delivery 
or acceptance, depending on terms of the sales arrangement. 

Service  revenues  derive  primarily  from  pilot  training  and  flight  operations  and  flight  management  activities.  Service 
revenues  are  recognized  as  the  services  are  performed.    Services  provided  pursuant  to  a  contract  are  either 
recognized over the contract period, or upon completion of the elements specified in the contract, depending on the 
terms of the contract. 

Interest income from investments in bonds and loans is earned under the constant yield method and includes accrual of 
interest  due  under  terms  of  the  bond  or  loan  agreement  as  well  as  amortization  of  acquisition  premiums  and 
accruable  discounts.    In  determining  the  constant  yield  for  mortgage-backed  securities,  anticipated  counterparty 
prepayments  are  estimated  and  evaluated  periodically.    Dividends  from  equity  securities  are  earned  on  the  ex-
dividend date. 

Operating revenue of utilities and energy businesses resulting from the distribution and sale of natural gas and electricity 
to  customers  is  recognized  when  the  service  is  rendered  or  the  energy  is  delivered.    Amounts  recognized  include 
unbilled as well as billed amounts.  Rates charged are generally subject to Federal and state regulation or established 
under  contractual  arrangements.  When  preliminary  rates  are  permitted  to  be  billed  prior  to  final  approval  by  the 
applicable  regulator,  certain  revenue  collected  may  be  subject  to  refund  and  a  provision  for  estimated  refunds  is 
accrued. 

Commission revenue from real estate brokerage transactions and related amounts due to agents which are included as 
components of operating revenues and expenses of utilities and energy businesses are recognized when a real estate 
transaction is closed. 

(k) 

Losses and loss adjustment expenses 
Liabilities  for  unpaid  losses  and  loss  adjustment  expenses  represent  estimated  claim  and  claim  settlement  costs  of 
property/casualty  insurance  and  reinsurance  contracts  with  respect  to  losses  that  have  occurred  as  of  the  balance 
sheet date.  The liabilities for losses and loss adjustment expenses are recorded at the estimated ultimate payment 
amounts,  except  that  amounts  arising  from  certain  workers’  compensation  reinsurance  business  are  discounted  as 
discussed below.  Estimated ultimate payment amounts are based upon (1) individual case estimates, (2) reports of 
losses from policyholders and (3) estimates of incurred but not reported (“IBNR”) losses. 

Provisions  for  losses  and  loss  adjustment  expenses  are  reported  in  the  accompanying  Consolidated  Statements  of 
Earnings  after  deducting  amounts  recovered  and  estimates  of  amounts  recoverable  under  reinsurance  contracts.  
Reinsurance contracts do not relieve the ceding company of its obligations to indemnify policyholders with respect 
to the underlying insurance and reinsurance contracts.

Losses and loss adjustment expenses (Continued) 
The estimated liabilities of workers’ compensation claims assumed under certain reinsurance contracts are carried in the 
Consolidated Balance Sheets at discounted amounts.  Discounted amounts are based upon an annual discount rate of 
4.5% for claims arising prior to 2003 and 1% for claims arising after 2002, consistent with discount rates used under 
statutory  accounting  principles.    The  periodic  discount  accretion  is  included  in  the  Consolidated  Statements  of 
Earnings as a component of losses and loss adjustment expenses. 

Deferred charges reinsurance assumed 
The excess of estimated liabilities for claims and claim costs over the consideration received with respect to retroactive 
property  and  casualty  reinsurance  contracts  that  provide  for  indemnification  of  insurance  risk  is  established  as  a 
deferred charge at inception of such contracts.  The deferred charges are subsequently amortized using the interest 
method  over  the  expected  claim  settlement  periods.  The  periodic  amortization  charges  are  reflected  in  the 
accompanying Consolidated Statements of Earnings as losses and loss adjustment expenses. 

Changes to the expected timing and estimated amount of loss payments produce changes in the unamortized deferred 
charge balance.  Such changes in estimates are determined retrospectively and included in insurance losses and loss 
adjustment expense in the period of the change. 

Insurance premium acquisition costs 
Costs that vary and are related to the issuance of insurance policies are deferred, subject to ultimate recoverability, and 
charged  to  underwriting  expenses  as  the  related premiums  are  earned.    Acquisition  costs  consist  of  commissions, 
premium  taxes,  advertising  and  other  underwriting  costs.    The  recoverability  of  premium  acquisition  costs, 
generally, reflects anticipation of investment income.  The unamortized balances of deferred premium acquisition 
costs  are  included  in  other  assets  and  were  $1,432  million  and  $1,287  million  at  December  31,  2006  and  2005, 
respectively. 

Regulated utilities and energy businesses 
Certain  domestic  energy  subsidiaries  prepare  their  financial  statements  in  accordance  with  SFAS  No.  71,  reflecting 
economic  effects  deriving  from  the  ability  to  recover  certain  costs  from  customers  and  the  requirement  to  return 
revenues  to  customers  in  the  future  through  the  regulated  rate-setting  process.    Accordingly,  certain  costs  are 
deferred  as  regulatory  assets  and  obligations  are  accrued  as  regulatory  liabilities,  which  will  be  amortized  over 
various future periods.  At December 31, 2006, MidAmerican had $1,827 million in regulatory assets and $1,839 
million  in  regulatory  liabilities,  which  are  components  of  other  assets  and  other  liabilities  of  utilities  and  energy 
businesses. 

Management continually assesses whether the regulatory assets are probable of future recovery by considering factors 
such as applicable regulatory changes, recent rate orders received by other regulated entities and the status of any 
pending or potential deregulation legislation.  If future recovery of costs ceases to be probable, the amount no longer 
probable of recovery is charged to earnings. 

Utilities  and  energy  businesses  recognize  legal  asset  retirement  obligations  (“ARO”),  mainly  related  to  the 
decommissioning  of  nuclear  generation  assets  and  the  final  reclamation  of  leased  coal  mining  property.    The 
estimated fair value of a legal ARO is recognized as a liability when a reasonable estimate of the expected future 
cash  flows  can  be  made.    This  liability  is  added  to  the  carrying  amount  of  the  associated  asset,  which  is  then 
depreciated  over  the  remaining  useful  life  of  the  asset.    Subsequent  to  the  initial  recognition,  the  liability  is 
periodically adjusted for revisions to assumptions used in determining the present value of the retirement obligation. 
The ARO as of December 31, 2006 was approximately $423 million and is reflected in other liabilities of utilities 
and energy businesses. 

(p) 

(q) 

Foreign currency 
The  accounts  of  foreign-based  subsidiaries  are  measured  in  most  instances  using  the  local  currency  as  the  functional 
currency.  Revenues and expenses of these businesses are translated into U.S. dollars at the average exchange rate 
for the period.  Assets and liabilities are translated at the exchange rate as of the end of the reporting period.  Gains 
or losses from translating the financial statements of foreign-based operations are included in shareholders’ equity 
as a component of accumulated other comprehensive income.  Unrealized gains or losses associated with available-
for-sale securities are included as a component of other comprehensive income.  Gains and losses arising from other 
transactions denominated in a foreign currency are included in the Consolidated Statements of Earnings. 

Deferred income taxes 
Deferred  income  taxes  are  calculated  under  the  liability  method.    Deferred  tax  assets  and  liabilities  are  based  on 
differences between the financial statement and tax basis of assets and liabilities at the enacted tax rates.  Changes in 
deferred  income  tax  assets  and  liabilities  that  are  associated  with  components  of  other  comprehensive  income 
(primarily unrealized investment gains and losses) are charged or credited directly to other comprehensive income. 
Otherwise, changes in deferred income tax assets and liabilities are included as a component of income tax expense. 
Valuation allowances have been established for certain deferred tax assets where realization is not likely.

Accounting pronouncements to be adopted in subsequent years 
In July 2006, the FASB issued FASB Interpretation No. 48 “Accounting for Uncertainty in Income Taxes” (“FIN 48”). 
FIN 48 prescribes a recognition threshold and measurement attribute for financial statement recognition of positions 
taken or expected to be taken in income tax returns.  Only tax positions meeting a “more-likely-than-not” threshold 
of being sustained are recognized under FIN 48.  FIN 48 also provides guidance on derecognition, classification of 
interest  and  penalties  and  accounting  and  disclosures  for  annual  and  interim  financial  statements.    FIN  48  is 
effective for fiscal years beginning after December 15, 2006.  The cumulative effect of any changes arising from the 
initial application of FIN 48 is required to be reported as an adjustment to the opening balance of retained earnings 
in the period of adoption. 

In  September  2006,  the  FASB  issued  FASB  Staff  Position  No.  AUG  AIR-1,  “Accounting  for  Planned  Major 
Maintenance  Activities”  (“AUG  AIR-1”).    AUG  AIR-1  prohibits  the  use  of  the  accrue-in-advance  method  of 
accounting  for  planned  major  maintenance  activities  in  which  such  maintenance  costs  are  ratably  recognized  by 
accruing  a  liability  in  periods  before  the  maintenance  is  performed.    This  pronouncement  also  retains  three 
alternative methods for accounting for planned major maintenance activities including the direct expensing method, 
the  built-in  overhaul  method  and  the  deferral  method.    AUG  AIR-1  is  effective  for  fiscal  years  beginning  after 
December 15, 2006. 

In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements” (“SFAS 157”).  SFAS 157 defines 
fair value as the price received to transfer an asset or paid to transfer a liability in an orderly transaction between 
market  participants  at  the  measurement  date  reflecting  the  highest  and  best  use  valuation  concepts.    SFAS  157 
establishes  a  framework  for  measuring  fair  value  by  creating  a  hierarchy  of  fair  value  measurements  currently 
required  under  GAAP  that  distinguishes  market  data  between  observable  independent  market  inputs  and 
unobservable  market  assumptions.    SFAS  157  further  expands  disclosures  about  such  fair  value  measurements. 
SFAS 157 is effective for fiscal years beginning after November 15, 2007 and may be adopted earlier but only if the 
adoption is in the first quarter of the fiscal year. 

In  February  2007,  the  FASB  issued  SFAS  No.  159,  “The  Fair  Value  Option  for  Financial  Assets  and  Financial 
Liabilities  -  Including  an  amendment  of  FASB  Statement  No.  115”  (“SFAS  No.  159”).    SFAS  No.  159  permits 
entities to elect to measure many financial instruments and certain other items at fair value.  Upon adoption of SFAS 
No. 159, an entity may elect the fair value option for eligible items that exist at the adoption date.  Subsequent to the 
initial  adoption,  the  election  of  the  fair  value  option  should  only  be  made  at  initial  recognition  of  the  asset  or 
liability or upon a remeasurement event that gives rise to new-basis accounting.  SFAS No. 159 does not affect any 
existing  accounting  literature  that  requires  certain  assets  and  liabilities  to  be  carried  at  fair  value  nor  does  it 
eliminate disclosure requirements included in other accounting standards.  SFAS No. 159 is effective for fiscal years 
beginning after November 15, 2007 and may be adopted earlier but only if the adoption is in the first quarter of the 
fiscal year. 

Berkshire  is  evaluating  the  impact  that  the  adoption  of  these  pronouncements  will  have  on  its  consolidated  financial 
position and currently does not anticipate that the adoption of these accounting pronouncements will have a material 
effect on its consolidated financial position.

Investments in MidAmerican Energy Holdings Company 

MidAmerican owns a combined regulated electric and natural gas utility company in the United States (MidAmerican Energy 
Company), a regulated electric utility company in the United States (PacifiCorp which was acquired March 21, 2006), two interstate 
natural gas pipeline companies in the United States (Kern River and Northern Natural Gas), two electricity distribution companies in 
the United Kingdom (Northern Electric and Yorkshire Electricity), a diversified portfolio of domestic and international electric power 
projects and the second largest residential real estate brokerage firm in the United States (HomeServices).  This group of businesses is 
referred to as “MidAmerican” or the “utilities and energy businesses.” 

On  February  9,  2006,  Berkshire  converted  its  non-voting  preferred  stock  to  common  stock  and  upon  conversion,  owned 
approximately  83.4%  (80.5%  diluted)  of  the  voting  common  stock  interests.    In  conjunction  with  the  acquisition  of  PacifiCorp, 
Berkshire  acquired  additional  common  stock  of  MidAmerican  for  $3.4  billion.    Berkshire’s  ownership  in  MidAmerican  as  of 
December 31, 2006 was 87.8% (86.6% diluted).  Accordingly, the 2006 Consolidated Financial Statements reflect the consolidation 
of the accounts of MidAmerican.  MidAmerican’s debt obligations are not guaranteed by Berkshire.  However, Berkshire has made a 
commitment until February 28, 2011 that would allow MidAmerican to request up to $3.5 billion of capital to pay its debt obligations 
or to provide funding to its regulated subsidiaries. 

During  2004  and  2005,  Berkshire  possessed  the  ability  to  exercise  significant  influence  on  the  operations  of  MidAmerican 
through its investments in common and convertible preferred stock of MidAmerican, which together possessed 9.7% of the voting 
rights and 83.4% (80.5% diluted) of the economic rights of MidAmerican.  The convertible preferred stock, although generally non-
voting, was substantially an identical subordinate interest to a share of common stock and economically equivalent to common stock. 
Therefore, during that period, Berkshire accounted for its investments in MidAmerican pursuant to the equity method.  An unaudited 
pro forma balance sheet as of December 31, 2005 is included on the face of the accompanying Consolidated Balance Sheets reflecting 
the consolidation of MidAmerican.  Walter Scott, Jr., a member of Berkshire’s Board of Directors, controlled approximately 86% of 
the  voting  interest  in  MidAmerican  at  December  31,  2005.    As  a  result  of  Berkshire’s  conversion  of  its  preferred  stock  to  voting 
common stock, at December 31, 2006, Mr. Scott’s voting interest has been reduced to 11%.

*  On  September  10,  2004,  MidAmerican’s  management  decided  to  cease  operations  of  mineral  extraction  facilities  installed  near  certain 
geothermal  energy  generation  sites  (“the  Project”)  at  which  proprietary  processes  were  used  to  extract  zinc  from  geothermal  brine  and  fluids.  
MidAmerican’s  management  concluded  that  the  Project  could  not  become  commercially  viable.    Consequently,  a  non-cash  impairment  charge  of 
approximately  $340  million,  after  tax,  was  recorded  to  write-down  assets  of  the  Project,  rights  to  quantities  of  extractable  minerals  and  allocated 
goodwill to estimated net realizable value. 

(3)  Significant business acquisitions 

Berkshire’s long-held acquisition strategy is to purchase businesses with consistent earning power, good returns on equity and 
able  and  honest  management  at  sensible  prices.    During  the  last  three  years,  Berkshire  acquired  several  businesses  which  are 
described in the following paragraphs. 

On June 30, 2005, Berkshire acquired Medical Protective Corporation (“MedPro”) from GE Insurance Solutions.  MedPro is 
one of the nation’s premier professional liability insurers for physicians, dentists and other primary health care providers.  On August 
31, 2005, Berkshire acquired Forest River, Inc., (“Forest River”) a leading manufacturer of leisure vehicles in the U.S.  Forest River 
manufactures a complete line of motorized and towable recreational vehicles, utility trailers, buses, boats and manufactured houses. 
Operating results of MedPro and Forest River are consolidated with Berkshire’s results beginning as of July 1, 2005 and September 1, 
2005, respectively.  Inclusion of MedPro’s and Forest River’s results as of the beginning of 2004 would not have materially impacted 
Berkshire’s  consolidated  results  of  operations  as  reported.    Aggregate  consideration  paid  for  all  business  acquisitions  completed 
during 2005, including smaller acquisitions directed by certain Berkshire subsidiaries, was $2.4 billion. 

On  February  28,  2006,  Berkshire  acquired  Business  Wire,  a  leading  global  distributor  of  corporate  news,  multimedia  and 
regulatory filings.  On March 21, 2006, PacifiCorp, a regulated electric utility providing service to customers in six Western states, 
was  acquired  for  approximately  $5.1  billion  in  cash.    On  May  19,  2006,  Berkshire  acquired  85%  of  Applied  Underwriters 
(“Applied”),  an  industry  leader  in  integrated  workers’  compensation  solutions.    Under  certain  conditions,  existing  minority 
shareholders of Applied may acquire up to an additional 4% interest in Applied from Berkshire. 

On July 5, 2006, Berkshire acquired 80% of the Iscar Metalworking Companies (“IMC”) for cash in a transaction that valued 
IMC at $5 billion.  IMC, headquartered in Israel, is an industry leader in the metal cutting tools business through its Iscar, TaeguTec, 
Ingersoll and other IMC companies.  IMC provides a comprehensive range of tools for the full scope of metalworking applications.  
IMC’s products are manufactured through a global network of world-class, technologically advanced manufacturing facilities located 
in Israel, Korea, the United States, Brazil, China, Germany, India, Italy and Japan, and are sold through subsidiary offices and agents 
located in 61 major industrial countries worldwide.  On August 2, 2006, Berkshire acquired Russell Corporation, a leading branded 
athletic apparel and sporting goods company for cash of approximately $600 million.

(2)  The FASB issued Staff Position No. FTB 85-4-1, “Accounting for Life Settlement Contracts by Third-Party Investors” (“FTB 85-4-1”) in 
2006, which provides guidance on the initial and subsequent measurement, financial statement presentation and disclosures for third-party investors 
in life settlement contracts.  Berkshire adopted FTB 85-4-1 as of January 1, 2006, and recorded an after-tax gain of $180 million which is reflected as 
an  increase  in  retained  earnings.    Berkshire  elected  to  use  the  investment  method  whereby  the  initial  transaction  price  plus  all  subsequent  direct 
external costs paid to keep the policy in force are capitalized. Death benefits received are applied against the capitalized costs and the difference is 
recorded in earnings.  Previously, life settlement contracts were valued at the cash surrender value of the underlying insurance policy.  During the 
second quarter of 2006, certain life settlement contracts were disposed of for proceeds of approximately $330 million.  Investments in life settlement 
contracts as of December 31, 2006 were insignificant.

Berkshire  utilizes  derivatives  in  order  to  manage  certain  economic  risks  of  its  businesses  as  well  as  to  assume  specified 
amounts of market risk from others.  The contracts summarized in the preceding table, with limited exceptions, are not designated as 
hedges for financial reporting purposes.  Changes in the fair values of derivative assets and derivative liabilities that do not qualify as 
hedges  are  reported  in  the  Consolidated  Statements  of  Earnings  as  derivative  gains/losses.    Since  January  2002,  the  operations  of 
General  Re  Securities  (“GRS”)  have  been  in  run-off.    As  of  December  31,  2006,  substantially  all  of  GRS’s  derivative  risks  (as 
measured by the gross notional value) that existed as of the commencement of the run-off have been liquidated. 

Master  netting  agreements  are  utilized  to  manage  counterparty  credit  risk,  where  gains  and  losses  are  netted  across  other 
contracts with that counterparty.  In addition, Berkshire may receive cash or securities from counterparties as collateral.  Likewise, 
Berkshire may be required to post cash or securities as collateral with counterparties under similar circumstances.  At December 31, 
2006, Berkshire held collateral with a fair value of $338 million, including cash of $314 million to secure open contract assets.  At 
December  31,  2006,  Berkshire  had  posted  no  collateral  with  counterparties  as  security  on  contract  liabilities.  Berkshire  may  be 
required  to  post  collateral  to  cover  derivative  liabilities  in  the  event  of  a  downgrade  of  its  credit  rating  below  specified  levels.  
Assuming  non-performance  by  all  counterparties  on  all  contracts  potentially  subject  to  a  credit  loss,  the  maximum  potential 
receivable loss, net of collateral held, at December 31, 2006 approximated $274 million. 

Berkshire  is  also  exposed  to  variations  in  the  market  prices  of  natural  gas  and  electricity  as  a  result  of  its  regulated  utility 
operations  and  uses  derivative  instruments,  including  forward  purchases  and  sales,  futures,  swaps  and  options  to  manage  these 
commodity  price  risks.    Derivative  instruments  are  recorded  in  the  Consolidated  Balance  Sheets  at  fair  value  as  either  assets  or 
liabilities unless they are designated as and qualify for normal purchases and normal sales exemptions under GAAP.  The majority of 
these contracts are either probable of recovery in rates and therefore recorded as a regulatory net asset or liability or are accounted for 
as cash flow hedges and therefore recorded as accumulated other comprehensive income.  Accordingly, amounts are generally not 
recognized in earnings until the contracts are settled.

Incurred losses “all prior accident years” reflects the amount of estimation error charged or credited to earnings in each calendar 
year with respect to the liabilities established as of the beginning of that year.  The beginning of the year net loss and loss adjustment 
expense liability was reduced by $1,071 million in 2006, $743 million in 2005 and $119 million in 2004.  In both 2005 and 2006, the 
reductions in loss estimates for occurrences in prior years were primarily due to lower than expected frequencies and severities on 
reported  and  settled  claims  in  the  primary  private  passenger  and  commercial  auto  lines  and  lower  than  expected  general  liability 
losses.    In  2006  and  2005,  developed  frequencies  were  generally  more  favorable  than  originally  expected,  particularly  for  liability 
coverages and claim severity increases were generally less than originally estimated.  In addition, in 2006 prior years loss estimates 
were reduced for certain casualty reinsurance claims as a result of lower than expected losses reported during the year.  Accident year 
loss  estimates  are  regularly  adjusted  to  consider  emerging  loss  development  patterns  of  prior  years  losses,  whether  favorable  or 
unfavorable. 

Prior  accident years  incurred  losses  also  include  amortization  of  deferred charges  related  to  retroactive  reinsurance  contracts 
incepting prior to the beginning of the year.  Amortization charges included in prior accident years losses were $358 million in 2006, 
$294 million in 2005 and $451 million in 2004.  Certain workers’ compensation reserves are discounted.  Net discounted liabilities at 
December 31, 2006 and 2005 were $2,705 million and $2,434 million, respectively, reflecting net discounts of $2,793 million and 
$2,798  million,  respectively.    Periodic  accretions  of  these  discounts  are  also  a  component  of  prior  years  losses  incurred.    The 
accretion of discounted liabilities was approximately $101 million in 2006, $92 million in 2005 and $87 million in 2004. 

Berkshire’s insurance subsidiaries are exposed to environmental, asbestos and other latent injury claims arising from insurance 
and  reinsurance  contracts.    Loss  reserve  estimates  for  environmental  and  asbestos  exposures  include  case  basis  reserves  and  also 
reflect  reserves  for  legal  and  other  loss  adjustment  expenses  and  IBNR  reserves.    IBNR  reserves  are  determined  based  upon 
Berkshire’s historic general liability exposure base and policy language, previous environmental loss experience and the assessment 
of  current  trends  of  environmental  law,  environmental  cleanup  costs,  asbestos  liability  law  and  judgmental  settlements  of  asbestos 
liabilities. 

The liabilities for environmental, asbestos and latent injury claims and claims expenses net of reinsurance recoverables were 
approximately  $5.1  billion  at  December  31,  2006  and  $5.4  billion  at  December  31,  2005.    These  liabilities  include  $3.8  billion  at 
December 31, 2006 and $4.0 billion at December 31, 2005, of liabilities assumed under retroactive reinsurance contracts.  Liabilities

arising  from  retroactive  contracts  with  exposure  to  claims  of  this  nature  are  generally  subject  to  aggregate  policy  limits.    Thus, 
Berkshire’s  exposure  to  environmental  and  latent  injury  claims  under  these  contracts  is,  likewise,  limited.    Berkshire  monitors 
evolving  case  law  and  its  effect  on  environmental  and  latent  injury  claims.    Changing  government  regulations,  newly  identified 
toxins,  newly  reported  claims,  new  theories  of  liability,  new  contract  interpretations  and  other  factors  could  result  in  significant 
increases in these liabilities.  Such development could be material to Berkshire’s results of operations.  It is not possible to reliably 
estimate the amount of additional net loss or the range of net loss that is reasonably possible.

Parent  company  debt  includes  several  individual  investment  agreement  borrowings  under  which  Berkshire  is  required  to 
periodically pay interest over the contract terms.  The weighted average interest rate on amounts outstanding as of December 31, 2006 
was 3.2%.  Under certain conditions, principal amounts may be redeemed without premium prior to the contractual maturity date at 
the option of the counterparties.  Parent company debt also includes $334 million principal amount of senior notes associated with 
SQUARZ  securities  issued  in  2002.    When  issued,  each  SQUARZ  security  consisted  of  a  3%  senior  note  due  in  November  2007 
together with a warrant which expires in May 2007.  The warrant permits each holder the right to purchase either 0.1116 shares of 
Class A common stock (effectively at $89,606 per share) or 3.3480 shares of Class B common stock (effectively at $2,987 per share) 
for $10,000.  A warrant premium is payable to Berkshire at an annual rate of 3.75%. 

Commercial paper and other short-term borrowings are utilized by certain subsidiaries as part of normal operations.  Weighted 
average  interest  rates  as  of  December  31,  2006  and  2005  were  5.4%  and  4.4%,  respectively.    Berkshire  subsidiaries  have 
approximately $4.2 billion of available unused lines of credit and commercial paper capacity to support their short-term borrowing 
programs and provide additional liquidity. 

Operating  subsidiary  and  project  debt  of  utilities  and  energy  businesses  represents  amounts  issued  by  subsidiaries  of 
MidAmerican pursuant to separate project financing agreements.  All or substantially all of the assets of certain utility subsidiaries are 
or may be pledged or encumbered to support or otherwise provide security.  These borrowing arrangements generally contain various 
covenants including, but not limited to, leverage ratios, interest coverage ratios and debt service coverage ratios.  As of December 31, 
2006, MidAmerican and its subsidiaries were in compliance with all applicable covenants.

(13)  Notes payable and other borrowings (Continued) 

Berkshire  Hathaway  Finance  Corporation  (“BHFC”), a  wholly-owned  subsidiary  of  Berkshire,  issued  senior  notes  at  various 
times  during  the  three  years  ending  December  31,  2005.    The  proceeds  were  used  in  the  financing  of  manufactured  housing  loan 
originations  and  portfolio  acquisitions  of  Clayton  Homes.    During  the  fourth  quarter  of  2006,  Clayton  Homes  borrowed 
approximately $1.3 billion whereby all principal and interest collected under certain manufactured housing loan portfolios, together 
with  any  repurchased  principal  on  such  loans  will  be  used  to  pay  the  principal  and  interest  on  these  borrowings.    The  expected 
weighted average life of the borrowings is approximately eight years.  The proceeds from these borrowings which are not guaranteed 
by Berkshire will be used to repay certain debt of BHFC. 

Generally, Berkshire’s guarantee of a subsidiary’s debt obligation is an absolute, unconditional and irrevocable guarantee for 

the full and prompt payment when due of all present and future payment obligations of the issuer.

Deferred  income  taxes  have  not  been  established  with  respect  to  undistributed  earnings  of  certain  foreign  subsidiaries.  
Earnings expected to remain reinvested indefinitely was approximately $1,762 million as of December 31, 2006.  Upon distribution 
as dividends or otherwise, such amounts would be subject to taxation in the United States as well as foreign countries.  However, U.S. 
income  tax  liabilities  could  be  offset,  in  whole  or  in  part,  by  tax  credits  allowable  from  taxes  paid  to  foreign  jurisdictions.  
Determination of the potential net tax due is impracticable due to the complexities of hypothetical calculations involving uncertain 
timing and amounts of taxable income and the effects of multiple taxing jurisdictions.

Notes to Consolidated Financial Statements (Continued) 
(14)  Income taxes (Continued) 

Berkshire and its subsidiaries’ income tax returns are continuously under audit by Federal and various local and international 
taxing authorities.  Berkshire’s consolidated Federal income tax return liabilities have been settled with the Internal Revenue Service 
through 1998.  Berkshire has received approximately $50 million in income tax refunds and interest with respect to certain issues in 
its Federal income tax returns dating back to 1988 that were litigated and for which a favorable ruling from the U.S. District Court 
was received in the fourth quarter of 2005.  Berkshire does not currently believe that the impact of potential future audit adjustments 
will have a material effect on its Consolidated Financial Statements. 

Charges for income taxes are reconciled to hypothetical amounts computed at the U.S. Federal statutory rate in the table shown 

below (in millions).

(15)  Dividend restrictions – Insurance subsidiaries 

Payments of dividends by insurance subsidiaries are restricted by insurance statutes and regulations.  Without prior regulatory 

approval, insurance subsidiaries may declare up to approximately $6.4 billion as ordinary dividends before the end of 2007. 

Combined  shareholders’  equity  of  U.S.  based  property/casualty  insurance  subsidiaries  determined  pursuant  to  statutory 
accounting rules (Statutory Surplus as Regards Policyholders) was approximately $59 billion at December 31, 2006 and $52 billion at 
December 31, 2005. 

Statutory  surplus  differs  from  the  corresponding  amount  determined  on  the  basis  of  GAAP.    The  major  differences  between 
statutory  basis  accounting  and  GAAP  are  that  deferred  charges  reinsurance  assumed,  deferred  policy  acquisition  costs,  unrealized 
gains and losses on investments in fixed maturity securities and related deferred income taxes are recognized under GAAP but not for 
statutory reporting purposes.  In addition, statutory accounting for goodwill of acquired businesses requires amortization of goodwill 
over 10 years, whereas under GAAP, goodwill is subject to periodic tests for impairment.

In determining fair value of financial instruments, Berkshire used quoted market prices when available.  For instruments where 
quoted market prices were not available, independent pricing services or appraisals by Berkshire’s management were used.  Those

(16)  Fair values of financial instruments (Continued) 
services and appraisals reflected the estimated present values utilizing current risk adjusted market rates of similar instruments.  The 
carrying  values  of  cash  and  cash  equivalents,  accounts  receivable  and  payable,  other  accruals,  securities  sold  under  agreements  to 
repurchase and other liabilities are deemed to be reasonable estimates of their fair values. 

Considerable  judgment  is  necessarily  required  in  interpreting  market  data  used  to  develop  the  estimates  of  fair  value. 
Accordingly, the estimates presented herein are not necessarily indicative of the amounts that could be realized in a current market 
exchange.  The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair 
value.

Each share of Class B common stock has dividend and distribution rights equal to one-thirtieth (1/30) of such rights of a Class 
A share. Accordingly, on an equivalent Class A common stock basis there are 1,542,649 shares outstanding as of December 31, 2006 
and 1,540,723 shares as of December 31, 2005. 

Each share of Class A common stock is convertible, at the option of the holder, into thirty shares of Class B common stock.  
Class B common stock is not convertible into Class A common stock.  On July 6, 2006, Berkshire’s Chairman and CEO, Warren E. 
Buffett converted 124,998 shares of Class A common stock into 3,749,940 shares of Class B common stock.  Each share of Class B 
common stock possesses voting rights equivalent to one-two-hundredth (1/200) of the voting rights of a share of Class A common 
stock.  Class A and Class B common shares vote together as a single class. 

(18)  Pension plans 

Several Berkshire subsidiaries individually sponsor defined benefit pension plans covering certain employees. Benefits under 
the  plans  are  generally  based  on  years  of  service  and  compensation,  although  benefits  under  certain  plans  are  based  on  years  of 
service and  fixed  benefit  rates.  The  companies  generally  contribute  to  the  plans  amounts  required  to  meet  regulatory  requirements 
plus additional amounts determined by management based on actuarial valuations.  The measurement date for the pension plans is 
predominantly December 31. 

In  September  2006,  the  FASB  issued  SFAS  No.  158,  “Employers’  Accounting  for  Defined  Benefit  Pension  and  Other 
Postretirement Plans – an amendment of FASB Statements No. 87, 88, 106 and 132(R)” (“SFAS No. 158”).  SFAS No. 158 requires 
an  employer  to  recognize  in  its  statement  of  financial  position  the  over-funded  or  under-funded  status  of  a  defined  benefit 
postretirement plan.  SFAS No. 158 also requires entities to recognize as a component of other comprehensive income, net of tax, the 
actuarial gains and losses and the prior service costs and credits that arise during the period, but are not recognized as components of 
net  periodic  benefit  cost  of  the  period  pursuant  to  SFAS  No.  87,  “Employers’  Accounting  for  Pensions”  and  SFAS  No.  106, 
“Employers’ Accounting for Postretirement Benefits Other Than Pensions.”  Berkshire adopted the recognition and related disclosure 
provisions of SFAS No. 158 as of December 31, 2006.  The incremental impact to the accompanying Consolidated Balance Sheet of 
such adoption is as follows (in millions).

In 2004, a Berkshire subsidiary amended its defined benefit plan to freeze benefits.  Such an event is considered a curtailment 
and  the  curtailment  gain  included  in  the  table  above  represents  the  elimination  of  projected  plan  benefits  and  the  recognition  of 
unamortized prior service costs and actuarial losses as of the amendment date. 

The accumulated benefit obligation is the actuarial present value of benefits earned based on service and compensation prior to 
the  valuation  date.  The  projected  benefit  obligation  is  the  actuarial  present  value  of  benefits  earned  based  upon  service  and 
compensation prior to the valuation date and includes assumptions regarding future compensation levels when benefits are based on 
those amounts.  Information regarding accumulated and projected benefit obligations is shown in the table that follows (in millions).

Benefit obligations under qualified U.S. defined benefit plans are funded through assets held in trusts and are not included as 
assets  in  Berkshire’s  Consolidated  Financial  Statements.    Pension  obligations  under  certain  non-U.S.  plans  and  non-qualified  U.S. 
plans are unfunded.  As of December 31, 2006, projected benefit obligations of non-qualified U.S. plans and non-U.S. plans which 
are not funded through assets held in trusts were $569 million.  A reconciliation of the changes in plan assets and a summary of plan 
assets held as of December 31, 2006 and 2005 is presented in the table that follows (in millions).

Pension plan assets are generally invested with the long-term objective of earning sufficient amounts to cover expected benefit 
obligations, while assuming a prudent level of risk. There are no target investment allocation percentages with respect to individual or 
categories of investments. Allocations may change rapidly as a result of changing market conditions and investment opportunities. 
The expected rates of return on plan assets reflect Berkshire’s subjective assessment of expected invested asset returns over a period 
of  several  years.    Berkshire  does  not  give  significant  consideration  to  past  investment  returns  when  establishing  assumptions  for 
expected long-term rates of returns on plan assets.  Actual experience will differ from the assumed rates, in particular over quarterly 
or annual periods, as a result of market volatility and changes in the mix of assets. 

The total net deficit status for plans (including unfunded plans) with accumulated benefit obligations in excess of plan assets 
was  $836  million  and  $589  million  as  of  December  31,  2006  and  2005,  respectively.    Expected  contributions  to  defined  benefit 
pension plans during 2007 are estimated to be $248 million.

Benefit  payments  over  the  next  ten  years,  which  reflect  expected  future  service  as  appropriate,  are  expected  to  be  paid  as 

follows (in millions):  2007 - $390; 2008 - $399; 2009 - $411; 2010 - $414; 2011 - $432; and 2012 to 2016 - $2,456. 

Weighted average interest rate assumptions used in determining projected benefit obligations were as follows.  These rates are 

substantially the same as the weighted average rates used in determining the net periodic pension expense.

Many Berkshire subsidiaries sponsor defined contribution retirement plans, such as 401(k) or profit sharing plans. Employee 
contributions  to  the  plans  are  subject  to  regulatory  limitations  and  the  specific  plan  provisions.   Berkshire  subsidiaries  may  match 
these  contributions  up  to  levels  specified  in  the  plans,  and  may  make  additional  discretionary  contributions  as  determined  by 
management.  The total expenses related to employer contributions for these plans were $498 million, $395 million and $338 million 
for the years ended December 31, 2006, 2005 and 2004, respectively.

(20)  Business segment data 

Berkshire’s  reportable  business  segments  are  organized  in  a  manner  that  reflects  how  management  views  those  business 
activities.    Certain  businesses  have  been  grouped  together  for  segment  reporting  based  upon  similar  products  or  product  lines, 
marketing, selling and distribution characteristics, even though those business units are operated under separate local management. 
There are over 40 separate business units. 

The  tabular  information  that  follows  shows  data  of  reportable  segments  reconciled  to  amounts  reflected  in  the  Consolidated 
Financial Statements.  Intersegment transactions are not eliminated in instances where management considers those transactions in 
assessing  the  results  of  the  respective  segments.  Furthermore,  Berkshire  management  does  not  consider  investment  and  derivative 
gains/losses or amortization of purchase accounting adjustments in assessing the performance of reporting units. Collectively, these 
items are included in reconciliations of segment amounts to consolidated amounts.

Notes to Consolidated Financial Statements (Continued) 

(21)  Contingencies and Commitments 

Berkshire and its subsidiaries are parties in a variety of legal actions arising out of the normal course of business. In particular, 
such  legal  actions  affect  Berkshire’s  insurance  and  reinsurance  businesses.    Such  litigation  generally  seeks  to  establish  liability 
directly  through  insurance  contracts  or  indirectly  through  reinsurance  contracts  issued  by  Berkshire  subsidiaries.    Plaintiffs 
occasionally  seek  punitive  or  exemplary  damages.    Berkshire  does  not  believe  that  such  normal  and  routine  litigation  will  have  a 
material effect on its financial condition or results of operations.  Berkshire and certain of its subsidiaries are also involved in other 
kinds of legal actions, some of which assert or may assert claims or seek to impose fines and penalties in substantial amounts and are 
described below. 

a) Governmental Investigations 

Berkshire,  General  Re  Corporation  (“General  Re”)  and  certain  of  Berkshire’s  insurance  subsidiaries,  including  General 
Reinsurance  Corporation (“General  Reinsurance”)  and  National  Indemnity Company  (“NICO”)  have  been continuing  to cooperate 
fully with the U.S. Securities and Exchange Commission (“SEC”), the U.S. Department of Justice, the U.S. Attorney for the Eastern 
District of Virginia and the New York State Attorney General (“NYAG”) in their ongoing investigations of non-traditional products.  
General Re originally received subpoenas from the SEC and NYAG in January 2005.  Berkshire, General Re, General Reinsurance 
and  NICO  have  been  providing  information  to  the  government  relating  to  transactions  between  General  Reinsurance  or  NICO  (or 
their respective subsidiaries or affiliates) and other insurers in response to the January 2005 subpoenas and related requests and, in 
the  case  of  General  Reinsurance  (or  its  subsidiaries  or  affiliates),  in  response  to  subpoenas  from  other  U.S.  Attorneys  conducting 
investigations relating to certain of these transactions.  In particular, Berkshire and General Re have been responding to requests from 
the  government  for  information  relating  to  certain  transactions  that  may  have  been  accounted  for  incorrectly  by  counterparties  of 
General Reinsurance (or its subsidiaries or affiliates).  Berkshire understands that the government is evaluating the actions of General 
Re and its subsidiaries, as well as those of their counterparties, to determine whether General Re or its subsidiaries conspired with 
others to misstate counterparty financial statements or aided and abetted such misstatements by the counterparties.  The government 
has  interviewed  a  number  of  current  and  former  officers  and  employees  of  General  Re  and  General  Reinsurance  as  well  as 
Berkshire’s Chairman and CEO, Warren E. Buffett, in connection with these investigations. 

In one case, a transaction initially effected with American International Group (“AIG”) in late 2000 (the “AIG Transaction”), 
AIG has corrected its prior accounting for the transaction on the grounds, as stated in AIG’s 2004 10-K, that the transaction was done 
to  accomplish  a  desired  accounting  result  and  did  not  entail  sufficient  qualifying  risk  transfer  to  support  reinsurance  accounting.  
General  Reinsurance  has  been  named  in  related  civil  actions  brought  against  AIG,  as  described  below.    As  part  of  their  ongoing 
investigations, governmental authorities have also inquired about the accounting by certain of Berkshire’s insurance subsidiaries for 
certain assumed and ceded finite reinsurance transactions. 

In  June  2005,  John  Houldsworth,  the  former  Chief  Executive  Officer  of  Cologne  Reinsurance  Company  (Dublin)  Limited 
(“CRD”),  a  subsidiary  of  General  Re,  and  Richard  Napier,  a  former  Senior  Vice  President  of  General  Re  who  had  served  as  an 
account  representative  for  the AIG  account,  each  pleaded  guilty  to  a federal  criminal  charge  of  conspiring  with  others  to  misstate 
certain  AIG  financial  statements  in  connection  with  the  AIG  Transaction  and  entered  into  a  partial  settlement  agreement  with  the 
SEC with respect to such matters.  In addition, Ronald Ferguson, General Re’s former Chief Executive Officer, Elizabeth Monrad, 
General Re’s former Chief Financial Officer, Christopher Garand, a former General Reinsurance Senior Vice President and Robert 
Graham, a former General Reinsurance Senior Vice President and Assistant General Counsel -- are awaiting trial in the U.S. District 
Court for the District of Connecticut on charges of conspiracy to violate securities laws and to commit mail fraud, securities fraud, 
making false statements to the SEC and mail fraud in connection with the AIG Transaction.  The trial is currently set for December 
2007.  Each has pleaded not guilty to all charges.  Each of these individuals, who had previously received a “Wells” notice in 2005 
from the SEC, is also the subject of an SEC enforcement action for allegedly aiding and abetting AIG’s violations of the antifraud 
provisions and other provisions of the federal securities laws in connection with the AIG Transaction.  The SEC case is presently 
stayed.  Joseph Brandon, the Chief Executive Officer of General Re, also received a “Wells” notice from the SEC in 2005. 

Various state insurance departments have issued subpoenas or otherwise requested that General Reinsurance, NICO and their 
affiliates provide documents and information relating to non-traditional products. The Office of the Connecticut Attorney General has 
also issued a subpoena to General Reinsurance for information relating to non-traditional products. General Reinsurance, NICO and 
their affiliates have been cooperating fully with these subpoenas and requests. 

In  November  2006,  two  subsidiaries  of  General  Re,  General  Reinsurance  UK  Limited  (“Gen  Re  UK”)  and  Kolnische 
Ruckversicherungs-Gesellschaft  AG  (“Cologne  Re”),  entered  into  a  settlement  agreement  with  the  Financial  Services  Authority 
(“FSA”)  with  respect  to  the  FSA’s  previously  disclosed  investigation  of  the  role  of  these  entities  in  certain  transactions  that  were 
alleged to involve no or insufficient risk transfer to be treated for accounting and regulatory purposes as reinsurance.  Pursuant to the 
settlement agreement, Gen Re UK paid the FSA a penalty of $2.3 million. 

Cologne Re is also cooperating fully with requests for information and orders to produce documents from the German Federal 
Financial Supervisory Authority (the “BaFin”) regarding the activities of Cologne Re relating to “finite reinsurance” and regarding 
transactions  between  Cologne  Re  or  its  subsidiaries,  including  CRD,  and  certain  counterparties.    In  particular,  Cologne  Re  is 
cooperating  fully  with  a  BaFin  order  to  produce  documents  received  on  October  24,  2006.    The  order  stated  that  it  is  part  of  the 
BaFin’s continuing investigation into financial reinsurance agreements and that Cologne Re, and possibly one or more of its senior 
executives, is suspected of violating legal provisions in regard to such agreements.

(21)  Contingencies and Commitments (Continued) 

In  April  2005,  the  Australian  Prudential  Regulation  Authority  (“APRA”)  announced  an  investigation  involving  financial  or 
finite  reinsurance  transactions  by  General  Reinsurance  Australia  Limited  (“GRA”),  a  subsidiary  of  General  Reinsurance.    An 
inspector  was  appointed  by  APRA  under  section  52  of  the  Insurance  Act  1973  to  conduct  an  investigation  of  GRA’s  financial  or 
finite  reinsurance  business.    GRA  and  General  Reinsurance  have  cooperated  fully  with  this  investigation.    The  inspector  has 
submitted its final investigative report to APRA. 

CRD  is  also  providing  information  to  and  cooperating  fully  with  the  Irish  Financial  Services  Regulatory  Authority  in  its 
inquiries regarding the activities of CRD. The Office of the Director of Corporate Enforcement in Ireland is conducting a preliminary 
evaluation  in  relation  to  CRD  concerning,  in  particular,  transactions  between  CRD  and  AIG.    CRD  is  cooperating  fully  with  this 
preliminary evaluation. 

General Reinsurance is also providing information to and cooperating fully with the Office of the Superintendent of Financial 

Institutions Canada in its inquiries regarding the activities of General Re and its affiliates relating to “finite reinsurance.” 

Berkshire cannot at this time predict the outcome of these matters and is unable to estimate a range of possible loss and cannot 
predict whether or not the outcomes will have a material adverse effect on Berkshire’s business or results of operations for at least the 
quarterly period when these matters are completed or otherwise resolved. 

b) Civil Litigation 

Litigation Related to ROA 

General  Reinsurance  and  several  current  and  former  employees,  along  with  numerous  other  defendants,  have  been  sued  in 
thirteen federal lawsuits involving Reciprocal of America (“ROA”) and related entities.  Nine are putative class actions initiated by 
doctors, hospitals and lawyers that purchased insurance through ROA or certain of its Tennessee-based risk retention groups.  ROA 
was a Virginia-based reciprocal insurer and reinsurer of physician, hospital and lawyer professional liability risks.  These complaints 
seek compensatory, treble, and punitive damages in an amount plaintiffs contend is just and reasonable.  General Reinsurance is also 
subject to actions brought by the Virginia Commissioner of Insurance, as Deputy Receiver of ROA, the Tennessee Commissioner of 
Insurance,  as  Receiver  for  purposes  of  liquidating  three  Tennessee  risk  retention  groups,  a  state lawsuit  filed  by a  Missouri-based 
hospital  group  that  was  removed  to  federal  court  and  another  state  lawsuit  filed  by  an  Alabama  doctor  that  was  also  removed  to 
federal court.  The first of these actions was filed in March 2003 and additional actions were filed in April 2003 through June 2006.  
In  the  action  filed  by  the  Virginia  Commissioner  of  Insurance,  the  Commissioner  asserts  in  several  of  its  claims  that  the  alleged 
damages are believed to exceed $200 million in the aggregate as against all defendants.  All of these cases are collectively assigned to 
the U.S. District Court for the Western District of Tennessee for pretrial proceedings.  General Reinsurance filed motions to dismiss 
all of the claims against it in these cases and, in June 2006, the court granted General Reinsurance’s motion to dismiss the complaints 
of the Virginia and Tennessee receivers.  The court granted the Tennessee receiver leave to amend her complaint, and the Tennessee 
receiver filed her amended complaint on August 7, 2006.  General Reinsurance has filed a motion to dismiss the amended complaint 
in its entirety and awaits a ruling by the court. The Virginia receiver has moved for reconsideration of the dismissal and for leave to 
amend his complaint.  General Reinsurance has filed its opposition to that motion and awaits a ruling by the court.  In September 
2006, the court also dismissed the complaint filed by the Missouri-based hospital group.  The Missouri-based hospital group has filed 
a  motion  for  reconsideration  of  the  dismissal  and  for  leave  to  file  an  amended  complaint.    General  Reinsurance  has  filed  its 
opposition to that motion and awaits a ruling by the court.  The court has also not yet ruled on General Reinsurance’s motions  to 
dismiss the complaints of the other plaintiffs. The parties have commenced discovery. 

In December 2006, General Reinsurance entered into settlement agreements with respect to two lawsuits filed in Alabama state 

courts that related to ROA and related entities, and these lawsuits have been dismissed. 

Actions related to AIG 

General Reinsurance is a defendant in In re American International Group Securities Litigation, Case No. 04-CV-8141-(LTS), 
United States District Court, Southern District of New York, a putative class action asserted on behalf of investors who purchased 
publicly-traded  securities  of  AIG  between  October  1999  and  March  2005.  The  complaint,  originally  filed  in  April  2005,  asserts 
various  claims  against  AIG  and  certain  of  its  officers,  directors,  investment  banks  and  other  parties,  including  Messrs.  Ferguson, 
Napier and Houldsworth (whom the Complaint defines, together with General Reinsurance, as the “General Re Defendants”).  The 
Complaint  alleges  that  the  General  Re  Defendants  violated  Section  10(b)  of  the  Securities  Exchange  Act  and  Rule  10b-5  in 
connection with the AIG Transaction.  The Complaint seeks damages and other relief in unspecified amounts.  General Reinsurance 
has answered the Complaint, denying liability and asserting various affirmative defenses.  Document production has begun, but no 
other discovery has taken place.  No trial date has been scheduled. 

A  member  of  the  putative  class  in  the  litigation  described  in  the  preceding  paragraph  has  asserted  similar  claims  against 
General Re and Mr. Ferguson in a separate complaint, Florida State Board of Administration v. General Re Corporation, et al., Case 
No. 06-CV-3967, United States District Court, Southern District of New York.   The claims against General Re and Mr. Ferguson 
closely resemble those asserted in the class action.  The complaint does not specify the amount of damages sought.  General Re has 
answered the Complaint, denying liability and asserting various affirmative defenses.  No trial date has been established.  The parties 
are  coordinating  discovery  and  other  proceedings  among  this  action,  a  similar  action  filed  by  the  same  plaintiff  against  AIG  and 
others, the class action described in the preceding paragraph, and the shareholder derivative actions described in the next paragraph.

Notes to Consolidated Financial Statements (Continued) 

(21)  Contingencies and Commitments (Continued) 

On July 27, 2005, General Reinsurance received a Summons and a Verified and Amended Shareholder Derivative Complaint 
in  In  re  American  International  Group,  Inc.  Derivative  Litigation,  Case  No.  04-CV-08406,  United  States  District  Court,  Southern 
District of New York.  The complaint, brought by several alleged shareholders of AIG, seeks damages, injunctive and declaratory 
relief  against  various  officers  and  directors  of  AIG  as  well  as  a  variety  of  individuals  and  entities  with  whom  AIG  did  business, 
relating to a wide variety of allegedly wrongful practices by AIG. The allegations relating to General Reinsurance focus on the AIG 
Transaction, and the complaint purports to assert causes of action in connection with that transaction for aiding and abetting other 
defendants’  breaches  of  fiduciary  duty  and  for  unjust  enrichment.  The  complaint  does  not  specify  the  amount  of  damages  or  the 
nature  of  any  other  relief  sought.    In  August  2005,  General  Reinsurance  received  a  Summons  and  First  Amended  Consolidated 
Shareholders’ Derivative Complaint in In re American International Group, Inc. Consolidated Derivative Litigation, Case No. 769-N, 
Delaware Chancery Court.  The claims asserted in the Delaware complaint are substantially similar to those asserted in the New York 
derivative  complaint,  except  that  the  Delaware  complaint  makes  clear  that  the  plaintiffs  are  asserting  claims  against  both  General 
Reinsurance  and  General  Re.    Proceedings  in  both  the  New  York  derivative  suit  and  the  Delaware  derivative  suit  are  stayed  until 
March 14, 2007. 

FAI/HIH Matter 

In December 2003, the Liquidators of both FAI Insurance Limited (“FAI”) and HIH Insurance Limited (“HIH”) advised GRA 
and Cologne Re that they intended to assert claims arising from insurance transactions GRA entered into with FAI in May and June 
1998.  In August 2004, the Liquidators filed claims in the Supreme Court of New South Wales in order to avoid the expiration of a 
statute  of  limitations  for  certain  plaintiffs.    The  focus  of  the  Liquidators’  allegations  against  GRA  and  Cologne  Re  are  the  1998 
transactions GRA entered into with FAI (which was acquired by HIH in 1999).  The Liquidators contend, among other things, that 
GRA and Cologne Re engaged in deceptive conduct that assisted FAI in improperly accounting for such transactions as reinsurance, 
and that such deception led to HIH’s acquisition of FAI and caused various losses to FAI and HIH.  The Liquidator of HIH served its 
Complaint on GRA and Cologne Re in June 2006.  The FAI Liquidator has until March 30, 2007 to serve his complaint on GRA and 
Cologne Re. 

Insurance Brokerage Antitrust Litigation 

Berkshire,  General  Re  and  General  Reinsurance  are  defendants  in  this  multi-district  litigation,  In  Re:  Insurance  Brokerage 
Antitrust Litigation, MDL No. 1663 (D.N.J.), in which plaintiffs allege an industry-wide scheme on the part of commercial insurance 
brokers  and  insurance  companies  to  defraud  a  purported  class  of  insurance  purchasers  through  bid-rigging  and  contingent 
commission arrangements.  The plaintiffs claim that all defendants engaged in a pattern of racketeering activity, in violation of RICO, 
and that they conspired to restrain trade.  They further allege that the broker defendants breached fiduciary duties to the plaintiffs, 
that the insurer defendants aided and abetted that breach, and that all defendants were unjustly enriched in the process.  Plaintiffs seek 
treble  damages  in  an  unspecified  amount,  together  with  interest  and  attorneys  fees  and  expenses.    They  also  seek  a  declaratory 
judgment of wrongdoing as well as an injunction against future anticompetitive practices.  In November 2006, General Re, General 
Reinsurance and Berkshire, together with the other defendants, filed motions to dismiss the complaint which are awaiting resolution. 

Berkshire  has  established  reserves  for  certain  of  the  legal  proceedings  discussed  above  where  it  has  concluded  that  the 
likelihood  of  an  unfavorable  outcome  is  probable  and  the  amount  of  the  loss  can  be  reasonably  estimated.    For  other  legal 
proceedings discussed above, either Berkshire has determined that an unfavorable outcome is reasonably possible but it is unable to 
estimate a range of possible losses or it is unable to predict the outcome of the matter.  Management believes that any liability to the 
Company that may arise as a result of current pending civil litigation, including the matters discussed above, will not have a material 
effect on Berkshire’s financial condition or results of operations. 

c) Commitments 

Berkshire subsidiaries lease certain manufacturing, warehouse, retail and office facilities as well as certain equipment. Total 
rent expense for all leases was $578 million, $432 million and $422 million in 2006, 2005 and 2004, respectively. Minimum rental 
payments for operating leases having initial or remaining non-cancelable terms in excess of one year are as follows.  Amounts are in 
millions.

commitments to purchase coal, electricity and natural gas.  Commitments under all such subsidiary arrangements are approximately 
$6.4 billion in 2007, $3.4 billion in 2008, $3.0 billion in 2009, $2.8 billion in 2010, $2.1 billion in 2011 and $7.3 billion after 2011.

(1)  On  February  9,  2006,  Berkshire  Hathaway  converted  its  non-voting  preferred  stock  of  MidAmerican  Energy  Holdings 
Company  (“MidAmerican”)  to  common  stock  and  upon  conversion,  owned  approximately  83.4%  (80.5%  diluted)  of  the 
voting  common  stock  interests.    Accordingly,  the  2006  Consolidated  Financial  Statements  reflect  the  consolidation  of  the 
accounts of MidAmerican. During the period between 2002 and 2005, Berkshire’s investment in MidAmerican was accounted 
for pursuant to the equity method. 

(2)  The  amount  of  investment  and  derivative  gains  and  losses  for  any  given  period  has  no  predictive  value,  and  variations  in 
amount  from  period  to  period  have  no  practical  analytical  value  in  view  of  the  unrealized  appreciation  in  Berkshire's 
investment portfolio.  After-tax investment and derivative gains were $1,709 million in 2006, $3,530 million in 2005, $2,259 
million in 2004, $2,729 million in 2003 and $566 million in 2002.  Investment gains in 2005 include a non-cash pre-tax gain 
of $5.0 billion ($3.25 billion after-tax) relating to the exchange of Gillette stock for Procter & Gamble stock. 

(3)  Net earnings for the year ending December 31, 2005 includes a pre-tax underwriting loss of $3.4 billion in connection with 
Hurricanes Katrina, Rita and Wilma that struck the Gulf coast and Southeast regions of the United States.  Such loss reduced 
net earnings by approximately $2.2 billion and earnings per share by $1,446.

Berkshire’s operating businesses are managed on an unusually decentralized basis.  There are essentially no centralized 
or  integrated  business  functions  (such  as  sales,  marketing,  purchasing,  legal  or  human  resources)  and  there  is  minimal 
involvement by Berkshire’s corporate headquarters in the day-to-day business activities of the operating businesses.  Berkshire’s 
corporate office management participates in and is ultimately responsible for significant capital allocation decisions, investment 
activities and the selection of the Chief Executive to head each of the operating businesses.  The business segment data (Note 20 
to the Consolidated Financial Statements) should be read in conjunction with this discussion.

Berkshire  engages  in  both  primary  insurance  and  reinsurance  of  property  and  casualty  risks.    Through  General  Re, 
Berkshire also reinsures life and health risks.  In primary insurance activities, Berkshire subsidiaries assume defined portions of 
the  risks  of  loss  from  persons  or  organizations  that  are  directly  subject  to  the  risks.    In  reinsurance  activities,  Berkshire 
subsidiaries assume defined portions of similar or dissimilar risks that other insurers or reinsurers have subjected themselves to in 
their own insuring activities.  Berkshire’s principal insurance and reinsurance businesses are: (1) GEICO, one of the four largest 
auto  insurers  in  the  U.S.,  (2)  General  Re,  (3)  Berkshire  Hathaway  Reinsurance  Group  and  (4)  Berkshire  Hathaway  Primary 
Group. 

On June 30, 2005, Berkshire acquired Medical Protective Corporation (“MedPro”), a provider of professional liability 
insurance  to  physicians,  dentists  and  other  healthcare  providers.    On  May  19,  2006,  Berkshire  acquired  85%  of  Applied 
Underwriters, a provider of integrated workers’ compensation solutions.  Underwriting results for these businesses are included 
in the Berkshire Hathaway Primary Group results beginning on their respective acquisition dates. 

Berkshire’s  management  views  insurance  businesses  as  possessing  two  distinct  operations  –  underwriting  and 
investing.  Underwriting decisions are the responsibility of the unit managers; investing, with limited exceptions at GEICO and 
General Re’s international operations, is the responsibility of Berkshire’s Chairman and CEO, Warren E. Buffett.  Accordingly, 
Berkshire evaluates performance of underwriting operations without any allocation of investment income. 

Periodic  underwriting  results  can  be  affected  significantly  by  changes  in  estimates  for  unpaid  losses  and  loss 
adjustment expenses, including amounts established for occurrences in prior years.  See the Critical Accounting Policies section 
of  this  discussion  for  information  concerning  the  loss  reserve  estimation  process.    In  addition,  the  timing  and  amount  of 
catastrophe  losses  can  produce  significant  volatility  in  periodic  underwriting  results.    During  the  third  quarter  of  2005, 
Hurricanes Katrina and Rita struck the Gulf Coast region of the United States producing the largest catastrophe losses for any 
quarter  in  the  history  of  the  property/casualty  insurance  industry.    In  the  fourth  quarter  of  2005,  Hurricane  Wilma  struck  the 
Southeast  U.S.    Estimated  pre-tax  losses  from  these  events  of  $3.4  billion  were  recorded  in  2005.    In  contrast,  there  were  no 
major hurricanes in 2006.

Insurance — Underwriting (Continued) 

A  key  marketing  strategy  followed  by  all  of  these  businesses  is  the  maintenance  of  extraordinary  capital  strength. 
Statutory surplus of Berkshire’s insurance businesses was approximately $59 billion at December 31, 2006.  This superior capital 
strength  creates  opportunities,  especially  with  respect  to  reinsurance  activities,  to  negotiate  and  enter  into  insurance  and 
reinsurance  contracts  specially  designed  to  meet  unique  needs  of  insurance  and  reinsurance  buyers.    Additional  information 
regarding Berkshire’s insurance and reinsurance operations follows. 

GEICO

GEICO  provides  primarily  private  passenger  automobile  coverages  to  insureds  in  49  states  and  the  District  of 
Columbia.  GEICO policies are marketed mainly by direct response methods in which customers apply for coverage directly to 
the company via the Internet, over the telephone or through the mail.  This is a significant element in GEICO’s strategy to be a 
low-cost insurer.  In addition, GEICO strives to provide excellent service to customers, with the goal of establishing long-term 
customer relationships. 

GEICO’s underwriting results for the past three years are summarized below.  Dollars are in millions.

Premiums  earned  in  2006  and  2005  increased  9.4%  and  13.3%,  respectively,  over  the  corresponding  prior  year 
amounts. The growth in premiums earned in 2006 for voluntary auto was 9.3% and reflects a 10.7% increase in policies-in-force 
during the past year.  During 2006, policies-in-force increased 11.3% in the preferred risk markets and 8.6% in the standard and 
nonstandard markets.  Voluntary auto new business sales in 2006 increased 8.8% compared to 2005.  Voluntary auto policies-in-
force  at  December  31,  2006  were  721,000  higher  than  at  December  31,  2005.    Premium  rates  have  been  reduced  and 
underwriting  guidelines  have  been  adjusted  in  certain  markets  to  better  match  price  with  the  underlying  risk  resulting  in 
relatively lower premiums per policy. 

Losses  and  loss  adjustment  expenses  in  2006  were  $7,749  million,  an  increase  of  8.7%  over  2005.    The  loss  ratio 
declined to 70.1% in 2006 compared to 70.6% in 2005 and 71.3% in 2004 primarily due to decreasing claim frequencies across 
all markets and most coverage types.  In 2006, claims frequencies for physical damage coverages decreased in the two to five 
percent range from 2005 while frequencies for injury coverages decreased in the two to five percent range.  Injury severity in 
2006 increased in the two to five percent range over 2005 while physical damage severity increased in the four to seven percent 
range.  Incurred losses from catastrophe events were approximately $54 million in 2006, $227 million in 2005 (primarily from 
the hurricanes in the third and fourth quarters) and $71 million in 2004. 

Underwriting  expenses  in  2006  were  $1,992  million,  an  increase  of  13.7%  over  2005,  which  increased  10.5%  over 
2004.    The  increase  in  expenses  in  2006  reflected  higher  advertising  costs  as  well  as  incremental  underwriting  and  policy 
issuance costs associated with new business sales. 

General Re 

General  Re  conducts  a  reinsurance  business  offering  property  and  casualty  and  life  and  health  coverages  to  clients 
worldwide.    In  North  America,  property  and  casualty  reinsurance  is  written  on  a  direct  basis  through  General  Reinsurance 
Corporation.    Internationally,  property  and  casualty  reinsurance  is  written  on  a  direct  basis  through  95%  owned  Cologne  Re 
(based in Germany) and other wholly-owned affiliates as well as through brokers with respect to Faraday in London.  Life and 
health  reinsurance  is  written  for  clients  worldwide  through  Cologne  Re.    General  Re’s  pre-tax  underwriting  results  are

Management’s Discussion (Continued) 

Insurance — Underwriting (Continued) 

Property/casualty 

Premiums written declined in 2006 from amounts written in 2005 which declined from amounts written in 2004.  The 
declines in North America were attributable to significant reductions in finite risk business and to a lesser extent lower casualty 
treaty volume.  International premiums written in 2006 were essentially unchanged from 2005. In local currencies, international 
premiums  written  increased  2%  over  2005  primarily  due  to  increased  volume  of  property  business  at  Faraday  offset  by  a 
significant  reduction  in  finite  risk  business.    The  overall  comparative  declines  in  written  premiums  in  the  past  three  years 
reflected continued underwriting discipline by rejecting transactions where pricing is deemed inadequate with respect to the risk. 

Approximately half of the comparative declines in the North American premiums earned in 2006 and 2005 versus the 
previous year were attributable to policy cancellations and non-renewals exceeding new contracts as well as a slight impact from 
rate changes.  The remainder of the comparative declines were primarily due to the significant decreases in finite risk business.  
In local currencies, 2006 international premiums earned declined 3.5% from 2005, which declined 12.3% compared with 2004. 
Similar  to  North  America,  the  decline  in  premiums  earned  in  the  international  segment  over  the  past  three  years  generally 
reflects reductions in premium volume due to the non-renewal of unprofitable business and the decrease in finite risk business. 

The North American business produced an underwriting gain of $127 million in 2006 compared with an underwriting 
loss  of  $307  million  in  2005  and  an  underwriting  gain  of  $11  million  in  2004.    Underwriting  results  in  2006  included  $348 
million  in  underwriting  gains  from  property  business  partially  offset  by  $221  million  in  underwriting  losses  from 
casualty/workers’  compensation  business  and  includes  legal  and  estimated  settlement  costs  associated  with  the  ongoing 
regulatory investigations of the finite risk business.  The property business produced underwriting gains of $209 million for the 
2006  accident  year,  and  $139  million  from  favorable  run-off  of  prior  year  property  losses.    The  current  accident  year  results 
benefited  from  a  lack  of  catastrophe  losses.    The  underwriting  losses  from  casualty/workers’  compensation  business  in  2006 
included  (1)  $137  million  in  discount  accretion  and  deferred  charge  amortization,  (2)  increases  in  prior  years’  workers’ 
compensation  reserves  of  $103  million  arising  from  the  continuing  escalation  of  medical  utilization  and  cost  inflation  and  (3) 
increases in asbestos and environmental reserves of $58 million.  These losses were somewhat offset by net decreases in prior 
years’ reserves for other casualty coverages. 

The  2005  underwriting  loss  included  approximately  $480  million  in  losses  from  three  major  hurricanes  in  2005 
(Katrina, Rita and Wilma).  Otherwise, underwriting results for the 2005 accident year generally benefited from re-pricing efforts 
and  improved  coverage  terms  and  conditions  put  into  place  over  the  preceding  few  years.  Underwriting  results  in  2005  also 
included losses attributable to prior accident years consisting of net reserve increases on workers’ compensation of $228 million, 
asbestos  and  environmental  mass  tort  exposures  of  $102  million  and  $136  million  in  discount  accretion  on  workers’ 
compensation  reserves  and  deferred  charge  amortization  on  retroactive  reinsurance  coverages.    Offsetting  these  prior  years’ 
losses were $419 million in gains from net reserve decreases in other casualty lines and property lines. 

The  net  underwriting  gain  of  $11  million  in  2004  consisted  of  current  accident  year  gains  of  $166  million  partially 
offset by $155 million in prior accident years’ losses.  The 2004 current accident year results benefited from a one-time reduction 
of $70 million in underwriting expenses from the curtailment of certain pension benefits.  In 2004, prior accident years’ losses 
included  reserve increases on casualty and workers’ compensation claims of $729 million and $110 million in discount accretion 
and deferred charge amortization offset by $307 million of reserve reductions for prior years’ property losses (primarily in World 
Trade Center loss exposures) and $377 million of gains from contract commutations and settlements. 

The International property/casualty businesses produced an underwriting gain of $246 million in 2006 compared with 
underwriting  losses  of  $138  million  and  $93  million  in  2005  and  2004,  respectively.    Underwriting  results  for  2006  benefited 
from $360 million of net gains in property and aviation lines of business and the lack of catastrophe losses.  Partially offsetting 
these gains were $114 million in net losses in casualty business, including costs associated with the finite risk business regulatory 
investigations.    Underwriting  results  for  both  2005  and  2004  included  catastrophe  losses  from  the  U.S.  hurricanes  of  $205 
million  and  $110  million,  respectively.    Additionally,  2005  results  included  $29  million  in  losses  from  windstorm  Erwin.  
Underwriting results for each of the last three years benefited from favorable results of the aviation and non-catastrophe property 
businesses.  The International property and casualty underwriting results included gains associated with prior accident years of 
$235 million in 2006 compared with gains of $108 million in 2005 and losses of $102 million in 2004.  Prior years’ losses in 
2004 were primarily in motor excess, workers’ compensation and other casualty lines and increases for operations placed in run-
off. 

Life/health 

Premiums earned in 2006 increased 3.0% over 2005, which increased 13.9% over 2004.  Adjusting for the effects of 
foreign currency, premiums earned increased 2.3% in 2006 and 14.2% in 2005.  The increase in premiums earned in 2006 was 
primarily from European life business and in 2005 was primarily due to an increase in both North American and European life 
business. 

The  global  life/health  operations  produced  underwriting  gains  of  $153  million  in  2006,  $111  million  in  2005  and  
$85  million  in  2004.    Both  the  U.S.  and  international  life/health  operations  were  profitable  in  each  of  the  past  three  years 
primarily  due  to  favorable  mortality;  however,  most  of  the  gains  were  earned  in  the  international  life  business.    Additionally, 
included in the underwriting results for 2006, 2005 and 2004 were $31 million, $66 million and $46 million, respectively, of net 
losses attributable to reserve increases on certain U.S. health business in run-off.

Insurance — Underwriting (Continued) 

Berkshire Hathaway Reinsurance Group

The  Berkshire  Hathaway  Reinsurance  Group  (“BHRG”)  underwrites  excess-of-loss  reinsurance  and  quota  share 
coverages for insurers and reinsurers worldwide.  BHRG’s business includes catastrophe excess-of-loss reinsurance and excess 
direct and facultative reinsurance for large or otherwise unusual discrete property risks referred to as individual risk.  Retroactive 
reinsurance  policies  provide  indemnification  of  losses  and  loss  adjustment  expenses  with  respect  to  past  loss  events.    Other 
multi-line  refers  to  other  business  written on both a quota-share and excess basis, participations in and contracts with Lloyd’s 
syndicates, as well as aviation business and workers’ compensation programs.  The timing and amount of catastrophe losses can 
produce  extraordinary  volatility  in  the  periodic  underwriting  results  of  the  BHRG,  and,  in  particular,  in  the  catastrophe  and 
individual  risk  business.    The  pre-tax  probable  maximum  loss  from  a  single  event  is  currently  estimated  to  be  approximately  
$6 billion.  BHRG’s pre-tax underwriting results are summarized below.  Amounts are in millions.

Includes losses of $2.5 billion from Hurricanes Katrina, Rita and Wilma. 

Catastrophe  and  individual  risk  contracts  may  provide  exceptionally  large  limits  of  indemnification,  often  several 
hundred million dollars and occasionally in excess of $1 billion, and cover catastrophe risks (such as hurricanes, earthquakes or 
other natural disasters) or other property risks (such as aviation and aerospace, commercial multi-peril or terrorism).  Catastrophe 
and individual risk premiums written were approximately $2.4 billion in 2006, $1.8 billion in 2005 and $1.5 billion in 2004.  The 
increase  in  volume  in  2006  was  principally  attributable  to  improved  rates  in  the  U.S.  and  limited  industry  capacity  for 
catastrophe reinsurance which led to more opportunities to write new business.  The level of business written in future periods 
may vary significantly based upon market conditions and management’s assessment of the adequacy of premium rates. 

Pre-tax  underwriting  results  in  2006  reflect  no  significant  losses  from  catastrophe  events  and  incurred  losses  of 
approximately $200 million attributable to prior years’ events, primarily Hurricane Wilma which occurred in the fourth quarter 
of 2005.  Underwriting results from catastrophe and individual risk business in 2005 included estimated losses of approximately 
$2.4  billion  from  Hurricanes  Katrina,  Rita  and  Wilma.    In  2004,  underwriting  results  from  catastrophe  and  individual  risk 
business included estimated catastrophe losses of $790 million from four hurricanes that struck the U.S. and Caribbean during 
the  third  quarter.    The  timing  and  magnitude  of  losses  produce  extraordinary  volatility  in  periodic  underwriting  results  of 
BHRG’s catastrophe and individual risk business. BHRG generally does not cede catastrophe and individual risks to mitigate the 
volatility.  Management accepts such potential volatility provided that the long-term prospect of achieving underwriting profits is 
reasonable. 

Retroactive  policies  normally  provide  very  large,  but  limited,  indemnification  of  unpaid  losses  and  loss  adjustment 
expenses with respect to past loss events that are expected to be paid over long periods of time.  The underwriting losses from 
retroactive  reinsurance  are  primarily  attributed  to  the  amortization  of  deferred  charges  established  on  retroactive  reinsurance 
contracts written in previous years.  The deferred charges, which represent the difference between the premium and the estimated 
ultimate  claim  reserves,  are  amortized  over  the  expected  claim  payment  period  using  the  interest  method.    The  amortization 
charges are recorded as losses incurred and, therefore, generate underwriting losses.  The level of amortization in a given period 
is based upon estimates of the timing and amount of future loss payments.  To the extent there are changes in these estimates, 
deferred charge balances are adjusted on a retrospective basis via a cumulative adjustment. 

Underwriting  losses  from  retroactive  reinsurance  in  2006  are  net  of  gains  of  approximately  $145  million  which 
primarily derived from contracts that were commuted or amended during the last half of 2006.  Underwriting losses in 2005 from 
retroactive reinsurance are net of a gain of approximately $46 million related to the final settlement of remaining unpaid losses 
under  a  retroactive  reinsurance  agreement.    In  addition,  estimates  of  unpaid losses were reviewed during the fourth quarter of 
2005 which resulted in a net reduction of $75 million in loss reserves and the rates of deferred charge amortization on certain 
other  contracts  were  decreased  due  to  slower  than  expected  loss  payments.    During  2004  the  estimated  timing  of  future  loss 
payments  with  respect  to  one  large  contract  was  accelerated  which  produced  an  incremental  amortization  charge  of 
approximately $100 million.  Unamortized deferred charges at December 31, 2006 were approximately $1.74 billion compared 
to $2.13 billion at December 31, 2005.  Management believes that these charges are reasonable with respect to the large amounts 
of float related to these policies.  Float was approximately $6.5 billion at December 31, 2006. 

Premiums earned from other multi-line reinsurance increased in 2006 as compared to 2005 due to the continued growth 
in  workers’  compensation  programs.    Increased  premiums  were  earned  in  2005  as  compared  to  2004  from  new  workers’ 
compensation  and  ongoing  aviation  programs  and  were  partially  offset  by  declines  in  quota-share  contracts.    Underwriting 
results  from  other  multi-line  reinsurance  in  2006  reflected  favorable  comparative  underwriting  results  from  property  contracts 
which benefited from low catastrophe losses.  These favorable comparative results were somewhat offset by a deterioration in 
underwriting  results  from  aviation  business.    Underwriting  results  in  2005  included  estimated  losses  of  approximately  $100 
million from Hurricanes Katrina, Rita and Wilma, while results in 2004 included losses of approximately $175 million arising 
from  the  third  quarter  hurricanes  affecting  the  U.S.  and  Caribbean.  However,  underwriting  gains  from  aviation  coverages  and 
approximately $160 million in gains from the commutations of several reinsurance contracts during 2004 more than offset the 
losses arising from catastrophes.

Insurance — Underwriting (Continued) 

Berkshire Hathaway Reinsurance Group (Continued) 

In November 2006, BHRG and Equitas, a London based entity established to reinsure and manage the 1992 and prior 
years’ non-life liabilities of the Names or Underwriters at Lloyd’s of London, entered into an agreement for BHRG to provide 
potentially  up  to  $7  billion  of  new  excess  reinsurance  to  Equitas.    BHRG  will  also  employ  the  current  staff  of  Equitas  and 
manage  the  run-off  of  Equitas’  liabilities.    The  agreement  is  subject  to  the  approval  by  certain  regulatory  authorities  in  the 
United  States  and  the  United  Kingdom  as  well  as  various  other  conditions  which  must  be  obtained  by  March  31,  2007.  
Consideration payable to BHRG under the arrangement would initially consist of all of Equitas’ assets less 100 million Pounds 
Sterling. 

Berkshire Hathaway Primary Group

Berkshire’s primary insurance group consists of a wide variety of smaller insurance businesses that principally write 
liability coverages for commercial accounts.  These businesses include:  National Indemnity Company’s primary group operation 
(“NICO  Primary  Group”),  a  writer  of  motor  vehicle  and  general  liability  coverages;  U.S.  Investment  Corporation  (“USIC”), 
whose  subsidiaries  underwrite  specialty  insurance  coverages;  a  group  of  companies  referred  to  internally  as  “Homestate” 
operations,  providers  of  standard  multi-line  insurance;  Central  States  Indemnity  Company  (“CSI”),  a  provider  of  credit  and 
disability  insurance  to  individuals  nationwide  through  financial  institutions;  and  MedPro  and  Applied  Underwriters,  which  as 
previously noted were acquired in June 2005 and May 2006, respectively. 

Collectively, Berkshire’s primary insurance businesses produced earned premiums of $1,858 million in 2006, $1,498 
million in 2005 and $1,211 million in 2004.  The increase in premiums earned in 2006 was primarily attributable to the impact of 
the  MedPro  and  Applied  Underwriters  acquisitions  partially  offset  by  a  decline  in  volume  of  the  NICO  Primary  Group.  
Premiums earned in the last half of 2005 by MedPro accounted for most of the increase in total premiums earned by the primary 
group in 2005 compared with 2004.  Pre-tax underwriting gains as percentages of premiums earned were approximately 18% in 
2006, 16% in 2005 and 13% in 2004.  Underwriting gains in 2006 were achieved in all of the businesses.  The underwriting gain 
in 2005 reflected a decrease in loss reserve estimates for pre-2005 loss events in the NICO Primary Group business, improved 
results of Homestate, USIC and CSI operations partially offset by losses incurred from increases in medical malpractice reserves. 

Insurance — Investment Income 

Following  is  a  summary  of  the  net  investment  income  of  Berkshire’s  insurance  operations  for  the  past  three  years.

Investment  income  consists  of  interest  and  dividends  earned  on  cash  equivalents  and  fixed  maturity  and  equity 
investments of Berkshire’s insurance businesses.  Pre-tax investment income earned in 2006 by Berkshire’s insurance businesses 
increased $836 million (24%) over 2005, which increased $656 million (23%) over 2004.  The increase in 2006 reflects higher 
short-term interest rates in the United States and increased dividends as compared to 2005.  The increase in investment income in 
2005 primarily reflects higher short-term interest rates in the United States as compared to 2004.

Insurance — Investment Income (Continued) 

All  U.S.  government  obligations  are  rated  AAA  by  the  major  rating  agencies  and  96%  of  all  state,  municipal  and 
political subdivisions, foreign government obligations and mortgage-backed securities were rated AA or higher.  Non-investment 
grade securities represent securities that are rated below BBB- or Baa3. 

Invested  assets  derive  from  shareholder  capital  and  reinvested  earnings  as  well  as  net  liabilities  assumed  under 
insurance  contracts  or  “float.”    The  major  components  of  float  are  unpaid  losses,  unearned  premiums  and  other  liabilities  to 
policyholders less premiums and reinsurance receivables, deferred charges assumed under retroactive reinsurance contracts and 
deferred policy acquisition costs.  Float approximated $50.9 billion at December 31, 2006, $49.3 billion at December 31, 2005 
and $46.1 billion at December 31, 2004.  The cost of float, as represented by the ratio of pre-tax underwriting gain or loss to 
average float, was negative for the last three years, as Berkshire’s insurance businesses generated pre-tax underwriting gains in 
each year.

*  Net of minority interests and includes interest earned by Berkshire (net of related income taxes).  Also includes additional 
income  tax  charges  of  $49  million  and  $15  million  in  2005  and  2004,  respectively,  related  to  Berkshire’s  accounting  for 
MidAmerican under the equity method. 

Berkshire’s 2005 and 2004 Consolidated Financial Statements reflect Berkshire’s share of MidAmerican’s net earnings 
as  determined  under  the  equity  method.    In  2006,  MidAmerican’s  revenues  and  expenses  are  consolidated  in  Berkshire’s 
financial statements.  For comparative purposes, revenues and earnings of MidAmerican for 2005 and 2004 are provided in the 
table above.  Revenues and earnings of the utilities and energy businesses are, to some extent, seasonal depending on weather-
induced demand.  Revenues from U.S. electricity sales are generally higher in the summer when air conditioning use is greatest 
and  revenues  from  gas  sales  and  pipelines  are  generally  higher  in  the  winter  when  heating  needs  are  higher.    Real  estate 
brokerage revenues tend to be highest in the second and third quarters. 

MidAmerican’s  revenues  of  $10,644  million  in  2006  increased  $3,364  million  (46%)  and  earnings  before  corporate 
interest  and  taxes  (“EBIT”)  of  $1,718  million  in  2006  increased  $550  million  (47%)  as  compared  to  2005.    The  increases  in 
revenues  and  EBIT  were  largely  attributable  to  the  acquisition  of  PacifiCorp  on  March  21,  2006.    Revenues  of  MidAmerican 
Energy Company (“MEC”) of $3,519 million increased $319 million (10%) as compared to 2005.  Major factors giving rise to 
MEC’s revenue increase were a change in strategy related to certain end use natural gas contracts that resulted in revenues and 
costs  being  recorded  on  a  gross  rather  than  net  basis  and  higher  wholesale  electricity  sales  due  to  both  price  and  volume 
increases.  Somewhat offsetting these increases were lower natural gas sales due to mild temperatures in 2006.  EBIT of MEC 
increased  $60  million  (21%)  as  compared  to  2005.    About  ⅔  of  the  increase  was  due  to  improved  margins  on  regulated 
electricity sales. 

Revenues from natural gas pipelines of $972 million in 2006 increased $63 million (7%) and EBIT of $376 million in 
2006 increased $67 million (22%) as compared to 2005.  The comparative improvement in revenues and EBIT was primarily due 
to  favorable  market  conditions  resulting  in  higher  demand  and  rates  as  well  as  additional  transportation  and  storage  services. 
EBIT of the U.K. utilities business of $338 million in 2006 increased $30 million (10%) as compared to 2005.  The increase was 
due to an increase in regulated revenues as well as a favorable impact from the strengthening of the Pound Sterling versus the 
U.S. dollar. 

Revenues from the real estate brokerage business of $1,724 million in 2006 decreased $170 million (9%) and EBIT of 
$74 million in 2006 decreased $74 million (50%) as compared to 2005.  The declines were due to a significant reduction in the 
number of closed transactions due to the significant slowdown in U.S. residential real estate activity. 

EBIT from other activities of $226 million in 2006 increased $111 million as compared to 2005.  Most of this increase 
arose from a gain on the sale of a security that was received in connection with a bankruptcy claim award as well as from sales of 
other investments.  In 2004, EBIT includes an impairment charge of $579 million related to the discontinuance of the operations 
of MidAmerican’s mineral extraction facility.

*  In  2004,  Berkshire  adopted  the  provisions  of  EITF  00-21  (“Accounting  for  Revenue  Arrangements  with  Multiple 
Deliverables”).    As  a  result,  for  consolidated  reporting  purposes,  the  method  of  recognizing  revenue  related  to  NetJets’ 
fractional  aircraft  sales  was  changed.    Management  continues  to  evaluate  the  results  of  NetJets  under  the  prior  revenue 
recognition criteria and thus has shown revenues and pre-tax earnings for the other services businesses using the prior revenue 
recognition method.  Revenues shown in this table are greater than the amounts reported in Berkshire’s consolidated financial 
statements by $781 million in 2006, $704 million in 2005 and $902 million in 2004.  Pre-tax earnings included in this table for 
2006, 2005 and 2004 exceed the amounts included in the consolidated financial statements by $79 million, $63 million and $74 
million, respectively. 

McLane Company 

McLane Company, Inc., (“McLane”) is a distributor of grocery and food products to retailers, convenience stores and 
restaurants.    McLane’s  business  is  marked  by  high  sales  volume  and  very  low  profit  margins.    McLane’s  revenues  in  2006 
increased $1,619 million (7%) as compared to 2005, which increased $701 million (3%) as compared to 2004.  The comparative 
revenue increases in both 2006 and 2005 were due to increased grocery business partially offset by comparative reductions in 
restaurant food service revenues primarily due to the loss of a large customer in mid-2005. 

Pre-tax earnings in 2006 increased $12 million over 2005 which reflects the increase in sales volume.  Pre-tax earnings 
in 2006 were negatively affected by a comparative 0.13% reduction in gross margin percentage which was primarily attributable 
to  increased  competition  in  the  grocery  business.    The  impact  from  the  decline  in  gross  margin  in  2006  was  largely  offset  by 
comparatively lower operating expenses that were primarily attributable to lower insurance costs.  About ⅓ of McLane’s annual 
revenues  are  to  Wal-Mart.    A  curtailment  of  purchasing  by  Wal-Mart  could  have  a  material  adverse  impact  on  revenues  and 
earnings of McLane. 

Shaw Industries 

Shaw Industries (“Shaw”) is the world’s largest manufacturer of tufted broadloom carpets and is a full-service flooring 
company.  Shaw’s revenues of $5,834 million in 2006 increased $111 million (2%) and pre-tax earnings of $594 million in 2006 
increased $109 million (22%) as compared to 2005.  The increase in revenues reflected a 7% increase in average selling price for 
carpet, partially offset by a 6% reduction in square yards sold.  The comparative decline in 2006 square yards sold versus 2005 
accelerated during the third and fourth quarters, which is attributed to a slowing of single-family housing construction and the 
acceleration of customer purchases during the second half of 2005 in anticipation of price increases.  The increase in earnings 
was primarily generated in the first six months of the year and was mainly attributable to a reduction in manufacturing cost per 
unit  deriving  from  the  integration  of  carpet  backing  and  nylon-fiber  manufacturing  operations  acquired  by  Shaw  in  the  fourth 
quarter of 2005.  These two acquisitions allow Shaw to internally produce most of its carpet backing needs and to secure a more 
stable  raw  material  source.    As  a  result  of  the  continued  slowdown  in  housing  construction  activity,  the  decline  in  volume  is 
expected to continue at least during the first half of 2007. 

Revenues  of  $5,723  million  in  2005  increased  $549  million  (11%)  and  pre-tax  earnings  of  $485  million  in  2005 
increased $19 million (4%) as compared to 2004.  Despite increases in selling prices, operating margins in 2005 were adversely 
affected  by  repeated  increases  in  petroleum-based  raw  material  costs.    Consequently,  increases  in  production  costs  outpaced 
increases  in  selling  prices.    In  addition,  product  sample  costs  pertaining  to  the  introduction  of  new  products  increased 
approximately $29 million in 2005 as compared to 2004. 

Other manufacturing 

Berkshire’s  other  manufacturing  businesses  include  a  wide  array  of  businesses.    Included  in  this  group  are  several 
manufacturers of building products (Acme Building Brands, Benjamin Moore, Johns Manville and MiTek) and apparel (Fruit of 
the  Loom,  Garan,  Russell  Corporation,  Fechheimers,  Justin  Brands  and  the  H.H.  Brown  Shoe  Group).    Also  included  in  this 
group  are  Forest  River,  a  leading  manufacturer  of  leisure  vehicles  that  was  acquired  on  August  31,  2005  and  the  Iscar 
Metalworking  Companies  (“IMC”),  an  industry  leader  in  the  metal  cutting  tools  business  with  operations  worldwide  that  was 
acquired on July 5, 2006.  Additionally, there are numerous other manufacturers of consumer and commercial products in this 
diverse group.

Manufacturing, Service and Retailing (Continued) 
Other manufacturing (Continued) 

Revenues from this group of manufacturing businesses of $11,988 million in 2006 increased $2,728 million (29%) and 
pre-tax earnings of $1,756 million in 2006 increased $421 million (32%) as compared to 2005.  The acquisitions of Forest River 
in August 2005, IMC in July 2006 and Russell Corporation in August 2006 account for a substantial portion of these increases. 
Revenues from other manufacturing businesses of $9,260 million in 2005 increased $1,108 million (14%) and pre-tax earnings 
increased $175 million (15%) as compared to 2004.  The aforementioned acquisition of Forest River accounted for a significant 
portion of the increase.  Additionally, the building products group of businesses reported significant increases in revenues and 
pre-tax  earnings  in  both  2006  and  2005  as  compared  to  the  prior  year.    However,  due  to  the  continued  slowdown  in  housing 
construction activity in the United States, earnings of the building products businesses are expected to be negatively impacted in 
2007 as compared to 2006. 

Other service 

Berkshire’s other service businesses include NetJets, the world’s leading provider of fractional ownership programs for 
general aviation aircraft and FlightSafety, a provider of high technology training to operators of aircraft and ships.  Among other 
businesses included in this group are Pampered Chef, a direct seller of high quality kitchen tools; International Dairy Queen, a 
licensor and service provider to about 6,000 stores that offer prepared dairy treats and food; the Buffalo News, a publisher of a 
daily and Sunday newspaper; and Business Wire, a leading distributor of corporate news, multimedia and regulatory filings. 

Revenues from the service businesses of $5,811 million in 2006 increased $1,083 million (23%) and pre-tax earnings 
of $658 million in 2006 increased $329 million (100%) as compared to 2005.  The largest portion of these increases arose from 
greatly improved comparative operating results at NetJets where revenues increased $759 million over 2005. NetJets generated 
pre-tax earnings of $143 million in 2006 as compared to a pre-tax loss of $80 million in 2005 reflecting a 23% increase in flight 
operations  and  management  service  revenues  and  increased  fractional  aircraft  sales.    In  2006,  occupied  flight  hours  increased 
19%  and  average  hourly  rates  increased  as  well.    The  number  of  aircraft  managed  within  the  NetJets  program  over  the  past 
twelve  months  increased  13%.    The  improvement  in  operating  results  at  NetJets  also  reflected  a  substantial  decline  in 
subcontracted flights that are necessary to meet peak customer demand, which resulted in a $77 million improvement in pre-tax 
earnings.  Comparative results in 2006 also benefited from the inclusion of Business Wire which was acquired in February 2006 
as well as comparative increases in revenues and earnings for FlightSafety. 

Revenues from other service businesses of $4,728 million in 2005 increased $221 million (5%) and pre-tax earnings of 
$329 million in 2005 declined $83 million (20%) as compared to 2004.  NetJets incurred a pre-tax loss of about $80 million in 
2005 compared to pre-tax earnings of about $10 million in 2004.  Several factors contributed to the loss in 2005.  Throughout 
2005, NetJets experienced unusually high shortages of available aircraft due to increases in owner demand outpacing increases in 
capacity.  Consequently, NetJets subcontracted additional aircraft capacity through charter services.  The costs associated with 
subcontracted  flights  were  not  fully  recoverable  from  clients  and  caused  an  incremental  cost  of  approximately  $85  million  in 
2005.  NetJets has added aircraft to the core fleet and has developed strategies to address capacity issues and restore profitability 
as the results in 2006 reflect. NetJets also recorded a special charge of $20 million in the fourth quarter of 2005 for prior periods’ 
compensation related to a new labor contract with its pilots and flight attendants. 

Retailing 

Berkshire’s  retailing  operations  consist  of  several  home  furnishings  (Nebraska  Furniture  Mart,  R.C.  Willey,  Star 
Furniture  and  Jordan’s)  and  jewelry  (Borsheim’s,  Helzbergs  and  Ben  Bridge)  retailers.    Also  included  in  this  group  is  See’s 
Candies.  Revenues from this group of businesses of $3,334 million in 2006 increased $223 million (7%) and pre-tax earnings of 
$289  million  increased  $32  million  (12%)  as  compared  to  2005.    Revenues  of  the  home  furnishings  businesses  were  $2,144 
million in 2006 and $1,958 million in 2005 and jewelry revenues were $815 million in 2006 and $801 million in 2005.  Home 
furnishings  revenues  in  2006  included  sales  from  two  new  R.C.  Willey  stores  of  $77  million.    In  addition,  same  store  home 
furnishings  sales  in  2006  increased  approximately  6%  compared  to  2005.    A  significant  portion  of  the  increase  in  pre-tax 
earnings was due to See’s Candies which reported an increase of approximately $27 million. 

Revenues from the retailing group of $3,111 million in 2005 increased $175 million (6%) and pre-tax earnings of $257 
million in 2005 increased $42 million (20%) in 2005 as compared to 2004.  Same store sales as well as new stores opened at R.C. 
Willey and Jordan’s and increased earnings at See’s contributed to these favorable comparative results.

Revenues and pre-tax earnings from manufactured housing and finance activities (Clayton Homes) increased 12% and 
23%, respectively, as compared to 2005.  In 2006, manufactured home sales increased $302 million as compared to 2005 which

was  primarily  due  to  slightly  increased  sales  of  higher  priced  homes  and  an  increase  in  total  units  sold.    However,  unit  sales 
during the second half of 2006 declined as compared to the second half of 2005.  Interest income from installment loans in 2006 
increased  $104  million  as  compared  to  2005  due  to  higher  average  installment  loan  balances  primarily  from  loan  portfolio 
acquisitions  during  2005.    The  balance  of  installment  loans  has  stabilized  after  significant  increases  in  recent  years.    Absent 
major  new  loan  portfolio  acquisitions  or  significant  increases  in  loan  originations,  installment  loan  balances  are  expected  to 
gradually decline as loan portfolios acquired in 2004 and 2005 are repaid.  Consequently, the rate of growth in interest income 
may decline over the next year and amounts may eventually decline in comparison with amounts earned in 2006. 

The  increase  in  revenues  in  2005  as  compared  to  2004  from  Clayton  Homes  was  primarily  attributable  to  increased 
sales  of  manufactured  homes  of  $491  million  and  increased  interest  income  of  $583  million  from  higher  installment  loan 
balances.    Installment  loan  balances  at  the  end  of  2005  increased  approximately  $8.5  billion  since  Berkshire’s  acquisition  of 
Clayton Homes in 2003, reflecting the impact of several loan portfolio acquisitions as well as loan originations.  Pre-tax earnings 
from Clayton Homes of $416 million in 2005, increased $224 million (117%) as compared to 2004.  The significant increase in 
pre-tax earnings was primarily due to higher interest income from the loan portfolios acquired during 2004 and 2005, partially 
offset by higher interest expenses. 

Pre-tax  earnings  from  other  finance  activities  of  $462  million,  increased  $229  million  as  compared  to  2005.    Other 
finance  activities  include  the  General  Re  derivatives  business,  which  has  completed  a  major  portion  of  its  run-off,  and 
Berkshire’s  earnings  from  its  investment  in  Value Capital, a partnership that was substantially liquidated as of June 30, 2006.  
These  two  activities  generated  breakeven  results  in  2006  compared  to  pre-tax  losses  of  $137  million  in  2005.    Other  pre-tax 
earnings for 2006 also include a fee of $67 million in connection with an Equity Commitment Agreement that Berkshire entered 
into with USG Corporation (“USG”).  Under the Equity Commitment Agreement, Berkshire agreed to purchase no less than 6.5 
million and up to 44.9 million additional shares of USG common stock to facilitate an equity rights offering.

Investment gains or losses are recognized upon the sales of investments or as otherwise required under GAAP.  The 
timing  of  realized  gains  or  losses  from  sales  can  have  a  material  effect  on  periodic  earnings.    However,  such  gains  or  losses 
usually have little, if any, impact on total shareholders’ equity because most equity and fixed maturity investments are carried at 
fair  value,  with  the  unrealized  gain  or  loss  included  as  a  component  of  other  comprehensive  income.    Other-than-temporary 
impairment  losses  represent  the  adjustment  of  cost  to  fair  value  when,  as  required  by  GAAP,  management  concludes  that  an 
investment’s decline in value below cost is other than temporary.  The impairment loss represents a non-cash charge to earnings. 

For  many  years,  Berkshire  held  an  investment  in  common  stock  of  The  Gillette  Company  (“Gillette”).    On  
October  1,  2005,  The  Procter  &  Gamble  Company  (“PG”)  completed  its  acquisition  of  Gillette  and  issued  0.975  shares  of  its 
common stock for each outstanding share of Gillette common stock.  Berkshire recognized a non-cash pre-tax investment gain of 
approximately $5 billion upon the exchange of the Gillette shares for PG shares.  Berkshire’s management does not regard the 
gain  that  was  recorded,  as  required  by  GAAP,  as  meaningful.  Berkshire  intends  to  hold  the  shares  of  PG  just  as  it  held  the 
Gillette  shares.    The  gain  recognized  for  financial  reporting  purposes  is  deferred  for  income  tax  purposes.    The  transaction 
essentially  had  no  effect  on  Berkshire’s  consolidated  shareholders’  equity  because  the  gain  included  in  earnings  in  the  fourth 
quarter  of  2005  was  accompanied  by  a  corresponding  reduction  of  unrealized  investment  gains  included in accumulated other 
comprehensive income. 

In  2004  and  2005,  life  settlement  investments  were  carried  at  the  cash  surrender  value  pursuant  to  FASB  Technical 
Bulletin (“FTB”) 85-4 “Accounting for Purchases of Life Insurance.”  The excess of the cash paid to purchase these contracts 
over the cash surrender value at the date of purchase was recognized as a loss immediately and periodic maintenance costs, such 
as premiums necessary to keep the underlying policies in force, were charged to earnings.  Effective January 1, 2006, Berkshire 
adopted the new accounting pronouncement FTB 85-4-1 and elected to use the investment method, whereby the aforementioned 
costs  were  capitalized.    The  cumulative  effect  of  the  accounting  change  which  increased  the  carrying  value  of  the  contracts

Investment and Derivative Gains/Losses (Continued) 

owned as of the adoption date was recorded, net of applicable income tax, as an increase to retained earnings of $180 million.  In 
2006,  Berkshire  disposed  of  most  of  the  life  settlement  contracts.    The  excess  of  the  proceeds  over  the  carrying  value  of  the 
contracts disposed of  represents most of the gain from these contracts in 2006. 

Derivative  gains  and  losses  from  foreign  currency  forward  contracts  arise  as  the  value  of  the  U.S.  dollar  changes 
against certain foreign currencies.  Small changes in certain foreign currency exchange rates produce material changes in the fair 
value  of  these  contracts  and  consequently  can  produce  volatility  in  reported  earnings.    The  notional  values  of  open  foreign 
currency  forward  contracts  were  approximately  $1  billion  and  $14  billion  as  of  December  31,  2006  and  2005,  respectively.  
During  2005,  the  value  of  most  foreign  currencies  decreased  relative  to  the  U.S.  dollar  and  these  contracts  produced  losses.  
Conversely,  the  value  of  many  foreign  currencies  rose  relative  to  the  U.S.  dollar  in  2004,  and  Berkshire’s  contract  positions 
produced significant gains. 

Over the past three years, Berkshire has also entered into several other derivative contracts pertaining to credit default 
risks of other entities as well as equity price risk associated with major equity indices.  Such contracts are carried at estimated 
fair value and the change in estimated fair value is included in earnings in the period of the change.  Other derivative contract 
gains  in  2006  derived  primarily  from  credit  default  contracts.    Management  attributes  the  gains  to  tightening  of  interest  rate 
spreads and market perceptions that the creditworthiness of many of the underlying credit issuers has improved. 

Financial Condition 

Berkshire’s  balance  sheet  continues  to  reflect  significant  liquidity  and  a  strong  capital  base.    Consolidated 
shareholders’  equity  at  December  31,  2006  was  $108.4  billion.    Consolidated  cash  and  invested  assets,  excluding  assets  of 
finance  and  financial  products  businesses,  was  approximately  $126.1  billion  at  December  31,  2006  (including  cash  and  cash 
equivalents  of  $38.3  billion)  and  $115.6  billion  at  December  31,  2005  (including  cash  and  cash  equivalents  of  $40.5  billion). 
Berkshire’s  invested  assets  are  held  predominantly  in  its  insurance  businesses.    Berkshire  believes  that  it  currently  maintains 
sufficient liquidity to cover its contractual obligations and provide for contingent liquidity. 

During  2006,  Berkshire  made  several  business  acquisitions  for  aggregate  cash  consideration  of  $10.1  billion.    See  
Note 3 to the Consolidated Financial Statements for more information concerning these acquisitions.  Berkshire maintains a large 
amount of capital in its insurance subsidiaries for strategic purposes and in support of reserves for unpaid losses.  In the United 
States, in particular, dividend payments by insurance companies are subject to prior approval by state regulators.  For the year 
ending December 31, 2006, Berkshire’s insurance subsidiaries paid dividends of $7.1 billion. 

Capital expenditures of the utilities and energy businesses were $2.4 billion in 2006. Capital expenditures, construction 
and  other  development  costs  for  the  year  ending  December  31,  2007  are  forecasted  to  be  approximately  $3.0  billion. 
MidAmerican  expects  to  fund  these  capital  expenditures  with  cash  flows  from  operations  and  the  issuance  of  debt.  
MidAmerican  utilizes  debt  to  finance  the  construction  of  long-lived  regulated  electric  and  gas  utility  assets,  including  power 
plants,  transmission  and  distribution  assets  and  natural  gas  pipelines  and  may  also  issue  debt  to  finance  operations.    Certain 
borrowings  of  its  regulated  utility  subsidiaries  are  secured  by  the  assets  of  those  subsidiaries.    As  of  December  31,  2006, 
outstanding debt of MidAmerican maturing in 2007 and 2008 was $3.6 billion, with an additional $1.7 billion due before 2012.  
During  2006,  Berkshire  made  a  five  year  commitment  to  provide  up  to  $3.5  billion  of  additional  capital  to  MidAmerican  to 
permit the repayment of its debt obligations or to fund its regulated utility subsidiaries.  Berkshire has not and does not intend to 
guarantee the repayment of debt by MidAmerican or any of its subsidiaries. 

Berkshire’s  consolidated  notes  payable  and  other  borrowings  of  insurance  and  other  businesses,  was  $3.7  billion  at 
December 31, 2006 and $3.6 billion at December 31, 2005.  As of December 31, 2006, outstanding borrowings include parent 
company  borrowings  of  $612  million  that  mature  in  2007,  including  senior  notes  issued  as  part  of  the  SQUARZ  securities  in 
2002.  The outstanding SQUARZ securities consist of $334 million principal amount of senior notes due in November 2007 and 
outstanding  warrants  that  expire  in  May  2007  to  purchase  3,716  Class  A  equivalent  shares  of  Berkshire  common  stock.    A 
warrant premium is payable to Berkshire at an annual rate of 3.75% and interest is payable to note holders at a rate of 3.00%. 
Each  warrant  provides  the  holder  the  right  to  purchase  either  0.1116  shares  of  Class  A  or  3.348  shares  of  Class  B  stock  for 
$10,000.  Short-term borrowings consist primarily of commercial paper and bank loans of NetJets, which are used in the ordinary 
course of business.  The full and timely payment of such borrowings is guaranteed by Berkshire. 

Assets of the finance and financial products businesses were $24.6 billion as of December 31, 2006 and $24.5 billion 
as  of  December  31,  2005,  consisting  primarily  of  loans  and  finance  receivables,  fixed  maturity  securities  and  cash  and  cash 
equivalents.  Liabilities were $19.4 billion as of December 31, 2006 and $20.3 billion as of December 31, 2005 and include notes 
and  other  borrowings  of  $12.0  billion  at  December  31,  2006  and  $10.9  billion  at  December  31,  2005.    Notes payable include 
$8.85  billion  par  amount  of  medium-term  notes  issued  by  Berkshire  Hathaway  Finance  Corporation  (“BHFC”).    The  notes 
mature  at  various  dates  beginning  in  2007  ($700  million)  through  2015.    The  proceeds  from these notes were used to finance 
originated and acquired loans of Clayton Homes.  Full and timely payment of principal and interest on the notes issued by BHFC 
is  guaranteed  by  Berkshire.    In  addition,  during  the  fourth  quarter  of  2006,  Clayton  Homes  borrowed  $1.3  billion  under  non-
public pass-through arrangements having an expected weighted average life of approximately eight years.  Such borrowings are 
secured by portfolios of manufactured housing loans and are not guaranteed by Berkshire.  The proceeds from these borrowings 
will be used to repay certain debt of BHFC.

Management’s Discussion (Continued) 

Contractual Obligations 

Berkshire and its subsidiaries are parties to contracts associated with ongoing business and financing activities, which 
will  result  in  cash  payments  to  counterparties  in  future  periods.    Notes  payable  are  reflected  in  the  Consolidated  Financial 
Statements along with accrued but unpaid interest as of the balance sheet date.  In addition, Berkshire is obligated to pay interest 
under debt obligations for periods subsequent to the balance sheet date.  Although certain principal balances may be prepaid in 
advance of the maturity date, thus reducing future interest obligations, it is assumed that no principal prepayments will occur for 
purposes  of  this  disclosure.    Further,  while  short-term  borrowings  and  repurchase  agreements  are  currently  expected  to  be 
renewed as they mature, such amounts are not assumed to renew for purposes of this disclosure. 

Berkshire and subsidiaries are also parties to long-term contracts to acquire goods or services in the future, which are 
not currently reflected in the financial statements.  Such obligations, including future minimum rentals under operating leases, 
will be reflected in future periods as the goods are delivered or services provided.  Amounts due as of the balance sheet date for 
purchases  where  the  goods  and  services  have  been  received  and  a  liability  incurred  are  not  included  to  the  extent  that  such 
amounts are due within one year of the balance sheet date. 

Contractual obligations for unpaid losses and loss adjustment expenses arising under property and casualty insurance 
contracts are estimates.  The timing and amount of such payments are contingent upon the ultimate outcome of claim settlements 
that  will  occur  over  many  years.    The  amounts  presented  in  the  following  table  have  been  estimated  based  upon  past  claim 
settlement activities. The timing and amount of such payments are subject to significant estimation error.  The factors affecting 
the  ultimate  amount  of  claims  are  discussed  in  the  following  section  regarding  Berkshire’s  critical  accounting  policies. 
Accordingly, the actual timing and amount of payments may differ materially from the amounts shown in the table. 

A  summary  of  long-term  contractual  obligations  as  of  December  31,  2006  follows.    Amounts  represent  estimates  of 
gross  undiscounted  amounts  payable  over  time.    In  addition,  certain  losses  and  loss  adjustment  expenses  for  property  and 
casualty loss reserves are ceded to others under reinsurance contracts and therefore are recoverable.  Such recoverables are not 
reflected in the table.  Amounts are in millions.

Critical Accounting Policies 

Certain accounting policies require management to make estimates and judgments concerning transactions that will be 
settled several years in the future.  Amounts recognized in the financial statements from such estimates are necessarily based on 
numerous  assumptions  involving  varying  and  potentially  significant  degrees  of  judgment  and  uncertainty.    Accordingly,  the 
amounts  currently  reflected  in  the  financial  statements  will  likely  increase  or  decrease  in  the  future  as  additional  information 
becomes available. 

Property and casualty losses 

A  summary  of  Berkshire’s  consolidated  liabilities  for  unpaid  property  and  casualty  losses  is  presented  in  the  table 
below.  Except for certain workers’ compensation reserves, liabilities for unpaid property and casualty losses (referred to in this 
section as “gross unpaid losses”) are reflected in the Consolidated Balance Sheets without discounting for time value, regardless

Property and casualty losses (Continued) 

Berkshire records liabilities for unpaid losses and loss adjustment expenses under property and casualty insurance and 
reinsurance contracts based upon estimates of the ultimate amounts payable under the contracts with respect to losses occurring 
on or before the balance sheet date.  Depending on the type of loss being estimated, the timing and amount of loss payments are 
subject  to  a  great  degree  of  variability  and  are  contingent,  among  other  things,  upon  the  timing  of  the  claim  reporting  from 
insureds  and  cedants  and  the  determination  and  payment  of  the  ultimate  loss  amount  through  the  loss  adjustment  process.    A 
variety  of  techniques  are  used  to  establish  and  review  the  liabilities  for  unpaid  losses  recorded  as  of  the  balance  sheet  date.  
While techniques may vary, significant judgments and assumptions are necessary in projecting the ultimate amount payable in 
the future with respect to loss events that have occurred.  As a result, uncertainties are imbedded in and permeate the actuarial 
loss reserving techniques and processes for all of Berkshire’s property and casualty insurance and reinsurance businesses. 

As of any balance sheet date, claims that have occurred have not all been reported, and if reported may not have been 
settled.  Loss  and  loss  adjustment  expense  reserves  include  provisions  for  those  claims  that  have  been  reported  (referred  to  as 
“case reserves”) and for those claims that have not been reported, referred to as incurred but not yet reported (“IBNR”) reserves.  
The  time  period  between  the  occurrence  date  and  payment  date  of  a  loss  is  referred  to  as  the  “claim-tail.”    Property  claims 
usually  have  fairly  short  claim-tails  and,  absent  litigation,  are  reported  and  settled  within  no  more  than  a  few  years  after 
occurrence.  Casualty losses usually have very long claim-tails, occasionally extending for decades.  Casualty claims are more 
susceptible to litigation and can be significantly affected by changing contract interpretations and the legal environment which 
contributes to the extended claim-tails. 

Receivables  recorded  with  respect  to  insurance  losses  ceded  to  other  reinsurers  under  reinsurance  contracts  are 
estimated in a manner similar to liabilities for insurance losses and, therefore, are also subject to estimation error.  In addition to 
the factors cited above, reinsurance recoverables may ultimately prove to be uncollectible if the reinsurer is unable to perform 
under  the  contract.  Reinsurance  contracts  do  not  relieve  the  ceding  company  of  its  obligations  to  indemnify  its  own 
policyholders. 

Each  of  Berkshire’s  insurance  businesses  utilize  loss  reserving  techniques  that  are  believed  to  best  fit  the  business.  
Additional  information  regarding  reserves  established  by  each  of  the  significant  businesses  (GEICO,  General  Re  and  BHRG) 
follows. 

GEICO 

GEICO’s gross unpaid losses and loss adjustment expense reserves as of December 31, 2006 were $6,095 million and 
net  of  reinsurance  recoverables  were  $5,814  million.    As  of  December  31,  2006,  gross  reserves  included  $4,315  million  of 
reported average, case and case development reserves and $1,780 million of IBNR reserves. 

GEICO  predominantly  writes  private  passenger  auto  insurance  which  has  a  relatively  short  claim-tail.   Accordingly, 
the  risk  of  estimation  error  is  thought  to  be  much  less  at  GEICO  than  for  either  General Re or BHRG.  The key assumptions 
affecting GEICO’s reserves include projections of ultimate claim counts (“frequency”) and average loss per claim (“severity”), 
which includes loss adjustment expenses. 

GEICO’s  reserving  methodologies  produce  reserve  estimates  based  upon  the  individual  claims  (or  a  “ground-up” 
approach), which in the aggregate yields a point estimate of the ultimate losses and loss adjustment expenses.  Ranges of loss 
estimates  are  not  determined  in  the  aggregate.    A  detailed  discussion  of  the  process  and  significant  factors  considered  in 
establishing reserves follows. 

Actuaries establish and evaluate unpaid loss reserves using recognized standard statistical loss development methods 
and techniques.  The significant reserve components (and percentage of gross reserves) are: (1) average reserves (20%), (2) case 
and  case  development  reserves  (50%),  and  (3)  IBNR  reserves  (30%).    Each  component  of  loss  reserves  is  affected  by  the 
expected frequency and average severity of claims.  Such amounts are analyzed using statistical techniques on historical claims 
data  and  adjusted  when  appropriate  to  reflect  perceived  changes  in  loss  patterns.    Data  is  analyzed  by  policy  coverage,  rated 
state, reporting date and occurrence date, among other factors.  A brief discussion of each component follows. 

Average  reserve  amounts  are  established  for  reported  auto  damage  claims  and  new  liability  claims  prior  to  the 
development of an individual case reserve.  The average reserves are established as a reasonable estimate for incurred claims for 
which claims adjusters have insufficient time and information to make a specific claim estimate.  It also includes a large number 
of minor physical damage claims that are paid within a reasonably short time after being reported.  Average reserve amounts are 
driven  by  the  estimated  average  severity  per  claim  and  the  number  of  new  claims  opened.    The  average  severity  per  claim 
amount is developed by projecting the ultimate severity for each accident quarter and weighting with both reported claims and 
estimated unreported claims. 

Claims adjusters generally establish individual liability claim case loss and loss adjustment expense reserve estimates 
as soon as the specific facts and merits of each claim can be evaluated.  Case reserves represent the amounts that in the judgment 
of the adjusters are reasonably expected to be paid in the future to completely settle the claim, including expenses.  Individual 
case reserves are revised as more information becomes known. 

For  most  liability  coverages,  case  reserves  alone  are  an  insufficient  measure  of  the  ultimate  cost  due  in  part  to  the 
longer claim-tail, the greater chance of protracted litigation and the incompleteness of facts available at the time the case reserve 
is  established.    Therefore,  additional  case  development  reserve  estimates  are  established,  usually  as  a  percentage  of  the  case 
reserve.  As of December 31, 2006, case development reserves averaged approximately 20% of total established case reserves.  
In general, case development factors are selected by a retrospective analysis of the overall adequacy of historical case reserves.  
Case development factors are reviewed and revised periodically.

Property and casualty losses (Continued) 

GEICO (Continued) 

For  unreported  claims,  IBNR  reserve  estimates  are  calculated  by  first  projecting  the  ultimate  number  of  claims 
expected  (reported  and  unreported)  for  each  significant  coverage  by  using  historical  quarterly  and  monthly  claim  counts,  to 
develop  age-to-age  projections  of  the  ultimate  counts  by  accident  quarter.    Reported  claims  are  subtracted  from  the  ultimate 
claim projections to produce an estimate of the number of unreported claims.  The number of unreported claims is multiplied by 
an estimate of the average cost per unreported claim to produce the IBNR reserve amount.  Actuarial techniques are difficult to 
apply  reliably  in  certain  situations,  such  as  to  new  legal  precedents,  class  action  suits  or  recent  catastrophes.    Consequently, 
supplemental IBNR reserves for these types of events may be established through the collaborative effort of actuarial, claims and 
other management. 

For  each  of  its  major  coverages,  GEICO  tests  the  adequacy  of  the  total  loss  reserves  using  one  or  more  actuarial 
projections based on claim closure models, paid loss triangles and incurred loss triangles.  Each type of projection analyzes loss 
occurrence data for claims occurring in a given period and projects the ultimate cost. 

In 2006, claim frequencies were  generally lower than expected and severity increases were generally not as great as 
originally projected.  Loss reserve estimates recorded at the end of 2005 developed downward by approximately $410 million 
when  reevaluated  at  December  31,  2006  producing  a  corresponding  increase  to  pre-tax  earnings  in  2006.    These  downward 
reserve developments represented approximately 4% of earned premiums in 2006 and approximately 7% of the prior year-end 
reserve amount.  Reserving assumptions at December 31, 2006 were modified appropriately to reflect the most recent frequency 
and severity results.  Future reserve development will depend on whether frequency and severity turn out to be more or less than 
anticipated.  Within the automobile line of business the reserves with the most uncertainty are for automobile liability, due to the 
longer  claim-tails  for  most  of  these  coverages.    Approximately  90%  of  GEICO’s  reserves  as  of  December  31,  2006  were  for 
automobile  liability,  of  which  bodily  injury  (“BI”)  coverage  accounted  for  nearly  60%  of  the  automobile  liability  reserves. 
Management believes it is reasonably possible that the average BI severity will change by at least one percentage point from the 
severity used.  If actual BI severity changes one percentage point from what was used in establishing the reserves, the reserves 
would develop up or down by approximately $90 million resulting in a corresponding decrease or increase in pre-tax earnings. 
Many  of  the  same  economic  forces  that  would  likely  cause  BI  severity  to  be  different  from  expected  would  likely  also  cause 
severities for other injury coverages to differ in the same direction. 

GEICO’s exposure to highly uncertain losses is believed to be limited to certain commercial excess umbrella policies 
written  during  a  period  from  1981  to  1984.    Remaining  reserves  associated  with  such  exposure  are  currently  a  relatively 
insignificant component of GEICO’s total reserves (less than 3%) and there is little, if any, apparent asbestos or environmental 
liability exposure.  Related claim activity over the past year was insignificant. 

General Re and BHRG 

General Re’s and BHRG’s property and casualty loss reserves derive primarily from assumed reinsurance.  Additional 
uncertainties unique to loss reserving processes for reinsurance are described below.  The nature, extent, timing and perceived 
reliability  of  information  received  from  ceding  companies  varies  widely  depending  on  the  type  of  coverage,  the  contractual 
reporting terms (which are affected by market conditions and practices) and other factors.  Due to the lack of standardization of 
the terms and conditions of reinsurance contracts, the wide variability of coverage needs of individual clients and the tendency 
for those needs to change rapidly in response to market conditions, the ongoing economic impact of such uncertainties, in and of 
themselves, cannot be reliably measured. 

The  nature  and  extent  of  loss  information  provided  under  many  facultative,  per  occurrence  excess  contracts  or 
retroactive  contracts  where  company  personnel  work  closely  with  the  ceding  company  in  settling  individual  claims  may  not 
differ significantly from the information received under a primary insurance contract.  Loss information from aggregate excess of 
loss  contracts,  including  catastrophe  losses  and  quota-share  treaties,  is  often  less  detailed.    Occasionally  such  information  is 
reported in summary format rather than on an individual claim basis.  Loss data is provided through periodic reports and may 
include  the  amount  of  ceded  losses  paid  where  reimbursement  is  sought  as  well  as  case  loss  reserve  estimates.    Ceding 
companies infrequently provide IBNR estimates to reinsurers. 

Each  of  Berkshire’s  reinsurance  businesses  has  established  practices  to  identify  and  gather  needed  information  from 
clients.    These  practices  include,  for  example,  comparison  of  expected  premiums  to  reported  premiums  to  help  identify 
delinquent  client  periodic  reports,  and  claim  reviews  to  facilitate  loss  reporting  and  identify  inaccurate  or  incomplete  claim 
reporting.    These  practices  are  periodically  evaluated  and  changed  as  conditions,  risk  factors,  and  unanticipated  areas  of 
exposures are identified. 

The timing of claim reporting to reinsurers is delayed in comparison with primary insurance.  In some instances there 
are  multiple  reinsurers  assuming  and  ceding  parts  of  an  underlying  risk  causing  multiple  contractual  intermediaries  between 
General  Re  or  BHRG  and  the  primary  insured.    In  these  instances,  the  delays  in  reporting  can  be  compounded.    The  relative 
impact  of  reporting  delays  on  the  reinsurer  varies  depending  on  the  type  of  coverage,  contractual  reporting  terms  and  other 
factors.  Contracts covering casualty losses on a per occurrence excess basis may experience longer delays in reporting due to the 
length of the claim-tail as regards to the underlying claim.  In addition, ceding companies may not report claims to the reinsurer 
until  it  becomes  reasonably  possible  that the reinsurer will be affected, usually determined as a function of its estimate of the 
claim  amount  as  a  percentage  of  the  reinsurance  contract  retention.    On  the  other  hand,  the  timing  of  reporting  large  per 
occurrence excess property losses or property catastrophe losses may not vary significantly from primary insurance.

Property and casualty losses (Continued) 

General Re and BHRG (Continued) 

Under  contracts  where  periodic  premium  and  claims  reports  are  required  from  ceding  companies,  such  reports  are 
generally required at quarterly intervals which in the U.S. range from 30 to 90 days after the end of the accounting period.  In 
continental Europe, reinsurance reporting practices vary.  Fewer clients report premiums, losses, and case reserves on a quarterly 
basis.  In certain countries, clients report on an annual basis and generally not until 90 to 180 days after the end of the annual 
period.  Estimates of premiums and losses are accrued based on expected results supplemented when necessary for estimates of 
significant  known  events  occurring  in  the  interim.    To  monitor  the  timing  and  receipt  of  information  due,  client  reporting 
requirements are tracked.  When clients miss reporting deadlines, the clients are contacted. 

Premium and loss data is provided through at least one intermediary (the primary insurer), so there is a greater risk that 
the  loss  data  provided  is  incomplete,  inaccurate  or  outside  the  coverage  terms.  Information  provided  by  ceding  companies  is 
reviewed  for  completeness  and  compliance  with  the  contract  terms.    Reinsurance  contracts  generally  allow  for  Berkshire’s 
reinsurance subsidiaries to have access to the cedant’s books and records as regards to the subject business and provide them the 
ability  to  conduct  audits  to  determine  the  accuracy  and  completeness  of  information.    Such  audits  are  conducted  when 
management deems it appropriate. 

In the regular course of business, disputes with clients may arise concerning whether certain claims are covered under 
the  reinsurance  policies.    Most  disputes  are  resolved  by  the  claims  departments  by  discussing  coverage  aspects  with  the 
appropriate client personnel or independent outside counsel review and determination. If disputes cannot be resolved, contracts 
generally specify whether arbitration, litigation, or alternative dispute resolution will be invoked.  There are no coverage disputes 
at this time for which an adverse resolution would likely have a material impact on Berkshire’s results of operations or financial 
condition. 

In  summary,  the  scope,  number  and  potential  variability  of  assumptions  required  in  estimating  ultimate  losses  from 
reinsurance contracts of General Re and BHRG are more uncertain than primary property and casualty insurers due to the factors 
previously discussed.  Additional information concerning General Re and BHRG follows.

General Re’s process of establishing loss reserve estimates is based upon a ground-up approach, beginning with case 
estimates and supplemented by additional case reserves (“ACRs”) and IBNR reserves.  Critical judgments in the establishment of 
these  loss  reserves  may  involve  the  establishment  of  ACRs  by  claim  examiners,  the  expectation  of  ultimate  loss  ratios  which 
drive IBNR reserve amounts and the case reserve reporting trends compared to the expected loss reporting patterns.  Recorded 
reserve amounts are subject to “tail risk” where reported losses develop beyond the maximum expected loss emergence pattern 
time period. 

The company does not routinely determine loss reserve ranges because it believes that the techniques necessary have 
not  sufficiently  developed  and  the  myriad  of  assumptions  required  render  such  resulting  ranges  to  be  unreliable.    In  addition, 
counts  of  claims  or  average  amounts  per  claim  are  not  utilized  because  clients  do  not  consistently  provide  reliable  data  in 
sufficient detail. 

Upon  notification  of  a  reinsurance claim from a ceding company, claim examiners make  independent evaluations of 
loss  amounts.    In  some  cases,  examiners’  estimates  differ  from  amounts  reported  by  ceding  companies.    If  the  examiners’ 
estimates  are  significantly  greater  than  the  ceding  company’s  estimates,  the  claims  are  further  investigated.    If  deemed 
appropriate,  ACRs  are  established  above  the  amount  reported  by  the  ceding  company.    As  of  December  31,  2006,  ACRs  of  
$3.4 billion before discounts were concentrated in workers’ compensation and to a lesser extent in professional liability reserves.  
Examiners also periodically conduct claim reviews at client companies and case reserves are often increased as a result.  In 2006, 
claim examiners conducted about 450 claim reviews. 

Actuaries  classify  all loss and premium  data into segments (“reserve cells”) primarily based on product (e.g., treaty, 
facultative, and program) and line of business (e.g., auto liability, property, etc.).  For each reserve cell, losses are aggregated by 
accident  year  and  analyzed  over  time.    Depending  on  client  reporting  practices,  some  losses  and  premiums  are  aggregated  by 
policy  year.    These  loss  aggregations  are  internally  called  loss  triangles,  which  serve  as  the  primary  basis  for  IBNR  reserve 
calculations.  Over 300 reserve cells are reviewed for North American business and approximately 900 reserve cells are reviewed 
with respect to international business.

Management’s Discussion (Continued) 

Property and casualty losses (Continued) 

General Re (Continued) 

Loss triangles are used to determine the expected case loss emergence patterns for most coverages and, in conjunction 
with expected loss ratios by accident year, are further used to determine IBNR reserves.  Additional calculations form the basis 
for estimating the expected loss emergence pattern.  The determination of the expected loss emergence pattern is not strictly a 
mechanical process.  In instances where the historical loss data is insufficient, estimation formulas are used along with reliance 
on other loss triangles and judgment.  Factors affecting loss development triangles include but are not limited to the following: 
changing client claims practices, changes in claim examiners’ use of ACRs or the frequency of client company claim reviews, 
changes in policy terms and coverage (such as client loss retention levels and occurrence and aggregate policy limits), changes in 
loss trends and changes in legal trends that result in unanticipated losses, as well as other sources of statistical variability.  These 
items influence the selection of the expected loss emergence patterns. 

Expected  loss  ratios  are  selected  by  reserve  cell,  by  accident  year,  based  upon  reviewing  forecasted  losses  and 
indicated ultimate loss ratios predicted from aggregated pricing statistics.  Indicated ultimate loss ratios are calculated using the 
selected loss emergence pattern, reported losses and earned premium.  If the selected emergence pattern is not accurate, then the 
indicated ultimate loss ratios will not be accurate and this can affect the selected loss ratios and hence the IBNR reserve.  As with 
selected loss emergence patterns, selecting expected loss ratios is not a strictly mechanical process and judgment is used in the 
analysis of indicated ultimate loss ratios and department pricing loss ratios. 

IBNR  reserves  are  estimated  by  reserve  cell,  by  accident  year,  using  the  expected  loss  emergence  patterns  and  the 
expected loss ratios.  The expected loss emergence patterns and expected loss ratios are the critical IBNR reserving assumptions 
and are updated annually.  Once the annual IBNR reserves are determined, actuaries calculate expected case loss emergence for 
the  upcoming  calendar  year.    This  calculation  does  not  involve  new  assumptions  and  uses  the  prior  year-end  expected  loss 
emergence patterns and expected loss ratios.  The expected losses are then allocated into interim estimates that are compared to 
actual reported losses in the subsequent year.  This comparison provides a test of the adequacy of prior year-end IBNR reserves 
and forms the basis for possibly changing IBNR reserve assumptions during the course of the year. 

In 2006, reported losses for North American workers’ compensation risks (primarily pre-2002 occurrences) exceeded 
expectations.  Claims data continued to show increased costs of long-term medical care and prescription drug costs and increased 
medical care utilization by claimants.  These developments produced changes in expectations for future development of reported 
claims  and  resulted  in  increases  in  nominal  ACRs.    For  prior  years’  workers’  compensation  losses,  reported  claims  exceeded 
expected claims in 2006 by $19 million.  These developments further precipitated a $132 million net increase in nominal IBNR 
reserve  estimates  for  unreported  occurrences.    After  deducting  $33  million  for  the  change  in  net  reserve  discounts  during  the 
year,  workers’  compensation  losses  from  prior  years’  reduced  pre-tax  earnings  in  2006  by  $118  million.    To  illustrate  the 
sensitivity of changes in expected loss emergence patterns and expected loss ratios for General Re’s significant excess of loss 
workers’ compensation reserve cells, an increase of ten points in the tail of the expected emergence pattern and an increase of ten 
percent in the expected loss ratios would produce a net increase in nominal IBNR reserves of approximately $548 million and 
$278  million  on  a  discounted  basis  as  of  December  31,  2006.    The  increase  in  discounted  reserves  would  produce  a 
corresponding  decrease  in  pre-tax  earnings.    Management  believes  it  is  reasonably  possible  for  the  tail  of  the  expected  loss 
emergence patterns and expected loss ratios to increase at these rates. 

Other  casualty  and  general  liability  reported  losses  (excluding  mass  tort  losses)  were  favorable  in  2006  relative  to 
expectations  after  several  years  of  relatively  higher  reported  losses.    Casualty  losses  tend  to  be  long-tail  and  it  should  not  be 
assumed  that  favorable  loss  experience  in  a  single  year  (2006)  means  that  loss  reserve  amounts  currently  established  will 
continue to develop favorably.  For General Re’s significant other casualty and general liability reserve cells (including medical 
malpractice, umbrella, auto and general liability), an increase of five points in the tails of the expected emergence patterns and an 
increase  of  five  percent  in  expected  loss  ratios  would  produce  a  net  increase  in  nominal  IBNR  reserves  and  a  corresponding 
reduction in pre-tax earnings of approximately $550 million.  Management believes it is reasonably possible for the tail of the 
expected loss emergence patterns and expected loss ratios to increase at these rates in any of the aforementioned reserve cells. 
However, given the diversification in worldwide business, more likely outcomes are believed to be less than $550 million. 

Property  losses  were  lower  than  expected  (including  losses  related  to  the  World  Trade  Center)  but  the  nature  of 
property loss experience tends to be more volatile because of the effect of catastrophes and large individual property losses.  In 
response to favorable claim developments and another year of information, estimated remaining World Trade Center losses were 
reduced by $62 million in 2006, producing a corresponding increase in pre-tax earnings. 

In  certain  reserve  cells  within  excess  directors  and  officers  and  errors  and  omissions  (“D&O  and  E&O”)  coverages, 
IBNR reserves are based on estimated ultimate losses without consideration of expected emergence patterns.  These cells often 
involve a spike in loss activity arising from recent industry developments making it difficult to select an expected loss emergence 
pattern.  For example, the recent wave of corporate scandals has caused an increase in reported losses.  For General Re’s large 
D&O  and  E&O  reserve  cells  an  increase  of  ten  points  in  the  tail  of  the  expected  emergence  pattern  (for  those  cells  where 
emergence  patterns  are  considered)  and  an  increase  of  ten  percent  in  the  expected  loss  ratios would  produce  a  net  increase  in 
nominal IBNR reserves and a corresponding reduction in pre-tax earnings of approximately $133 million.  Management believes 
it is reasonably possible for the tail of the expected loss emergence patterns and expected loss ratios to increase at these rates. 

Overall  industry-wide  loss  experience  data  and  informed  judgment  are  used  when  internal  loss  data  is  of  limited 
reliability, such as in setting the estimates for mass tort, asbestos and hazardous waste (collectively, “mass tort”) claims.  Unpaid 
mass  tort  reserves  at  December  31,  2006  were  approximately  $1.9  billion  gross  and  $1.2  billion  net  of  reinsurance.    Such  

68 

 
 
Property and casualty losses (Continued) 
General Re (Continued) 

reserves  were  approximately  $1.8  billion  gross  and  $1.3  billion  net  of  reinsurance  as  of  December  31,  2005.    Claims  paid 
attributable to such losses were about $97 million in 2006.  In 2006, reserves for mass tort claims were increased in response to 
continued reports of losses and the increased uncertainty of how, when and how much these types of losses will develop over 
time.  In 2006, IBNR reserve estimates for asbestos and environmental claims were increased by $58 million, which decreased 
pre-tax earnings by $58 million.  In addition to the previously described methodologies, General Re considers “survival ratios” 
based on net claim payments in recent years versus net unpaid losses as a rough guide to reserve adequacy.  The survival ratio 
was  approximately  13  years  as  of  December  31,  2006.    The  insurance  industry’s  comparable  survival  ratio  for  asbestos  and 
pollution  reserves  was  approximately  nine  years.    Estimating  mass  tort  losses  is  very  difficult  due  to  the  changing  legal 
environment.  Although such reserves are believed to be adequate, significant reserve increases may be required in the future if 
new exposures or claimants are identified, new claims are reported or new theories of liability emerge.

In  general,  the  methodologies  used  to  establish  loss  reserves  vary  widely  and  encompass  many  of  the  common 
methodologies  employed  in  the  actuarial  field  today.  Certain  traditional  methodologies  such  as  paid  and  incurred  loss 
development  techniques,  incurred  and  paid  loss  Bornhuetter-Ferguson  techniques  and  frequency  and  severity  techniques  are 
utilized.  Additional  judgments  must  also  be  employed  to  consider  changes  in  contract  conditions  and  terms  as  well  as  the 
incidence of litigation or legal and regulatory change. 

As  of  December  31,  2006,  BHRG’s  gross  loss  reserves  related  to  retroactive  reinsurance  policies  were  attributed  to 
casualty losses.  Retroactive policies include excess-of-loss contracts, in which losses (relating to loss events occurring before a 
specified date on or before the contract date) above a contractual retention are indemnified or contracts that indemnify all losses 
paid  by  the  counterparty  after  the  policy  effective  date.    Retroactive  losses  paid  in  2006  were  $858  million,  essentially  all  of 
which pertained to pre-2006 contracts.  The classification “reported case reserves” has no practical analytical value with respect 
to retroactive policies since the amount is often derived from reports in bulk from ceding companies, who may have inconsistent 
definitions of “case reserves.”  Reserves are reviewed and established in the aggregate by contract including provisions for IBNR 
reserves. 

In establishing retroactive reinsurance reserves, historical aggregate loss payment patterns are analyzed and projected 
into  the  future  under  various  scenarios.    The  claim-tail  is  expected  to  be  very  long  for  many  policies  and  may  last  several 
decades.    Management  assigns  judgmental  probability  factors  to  these  aggregate  loss  payment  scenarios  and  an  expectancy 
outcome is determined.  Management monitors claim payment activity and reviews ceding company reports or other information 
concerning  the  underlying  losses.    Since  the  claim-tail  is  expected  to  be  very  long  for  such  contracts,  management  reassesses 
expected ultimate losses as significant events related to the underlying losses are reported or revealed during the monitoring and 
review  process.    During  2006,  retroactive  reserves  developed  downward  by  approximately  $235  million,  due  primarily  to 
commutations of contracts where final loss payments were less than the recorded reserves. 

BHRG’s  liabilities  for  environmental,  asbestos,  and  latent  injury  losses  and  loss  adjustment  expenses  are  presently 
concentrated within retroactive reinsurance contracts.  Reserves for such losses were approximately $3.8 billion at December 31, 
2006 and $4.0 billion at December 31, 2005.  Losses paid in 2006 were approximately $300 million.  BHRG, as a reinsurer, does 
not  regularly  receive  reliable  information  regarding  numbers  of  asbestos,  environmental  and  latent  injury  claims  from  ceding 
companies on a consistent basis, particularly with respect to multi-line treaty or aggregate excess of loss policies.  Periodically, a 
ground-up  analysis  of  the  underlying  loss  data  of  the  reinsured  is  conducted to make an estimate of ultimate reinsured losses.  
When  detailed  loss  information  is  unavailable,  estimates  can  only  be  developed  by  applying  recent  industry  trends  and 
projections  to  aggregate  client  data.    Judgments  in  these  areas  necessarily  include  the  stability  of  the  legal  and  regulatory 
environment  under  which  these  claims will be adjudicated.  The increasing number of bankruptcies of asbestos manufacturers 
has  adversely  impacted  trends  in  recent  years.    Potential  legal  reform  and  legislation  could  also  have  a  significant  impact  on 
establishing loss reserves for mass tort claims in the future. 

The  maximum  losses  payable  by  BHRG  under  retroactive  policies  are  not  expected  to  exceed  approximately  $10.8 
billion as of December 31, 2006.  Absent significant judicial or legislative changes affecting asbestos, environmental or latent 
injury exposures, management believes it unlikely that unpaid losses as of December 31, 2006 ($8.1 billion) will develop upward 
to the maximum loss payable or downward by more than 15%. 

A  significant  number  of  recent  reinsurance  contracts  are  expected  to  have  a  low  frequency  of  claim  occurrence 
combined with a potential for high severity of claims.  These include losses from catastrophes, terrorism, and aviation risks under 
catastrophe  and  individual  risk  contracts.    Loss  reserves  related  to  catastrophe  and  individual  risk  contracts  decreased  from 
approximately $3.5 billion at year end 2005 to approximately $2.2 billion at year end 2006.  The decrease in reserves reflected 
loss payments in 2006 of approximately $1.7 billion that were primarily attributable to the major hurricanes that occurred in 2005.

Management’s Discussion (Continued) 

Property and casualty losses (Continued) 
BHRG (Continued) 

Partially  offsetting  the  effect  of  the  loss  payments  were  increases  in  loss  reserves  on  pre-2006  events  of  approximately  $200 
million that produced a corresponding charge to pre-tax earnings in 2006.  The reserve increases were primarily due to higher 
than  expected  reported  losses  on  Hurricane  Wilma  which  occurred  in  the  fourth  quarter  of  2005.    Reserving  techniques  for 
catastrophe and individual risk contracts generally rely more on a per-policy assessment of the ultimate cost associated with the 
individual loss event rather than with an analysis of the historical development patterns of past losses.  Catastrophe loss reserves 
are provided when it is probable that an insured loss has occurred and the amount can be reasonably estimated.  Absent litigation 
affecting the interpretation of coverage terms, the expected claim-tail is relatively short and thus the estimation error in the initial 
reserve estimates usually emerges within 24 months after the loss event. 

Other reinsurance reserve amounts are generally based upon loss estimates reported by ceding companies and IBNR 
reserves  that  are  primarily  a  function  of  reported  losses  from  ceding  companies  and  anticipated  loss  ratios  established  on  an 
individual contract basis, supplemented by management’s judgment of the impact on each contract of major catastrophe events 
as  they  become  known.    Anticipated  loss  ratios  are  based  upon  management’s  judgment  considering  the  type  of  business 
covered, analysis of each ceding company’s loss history and evaluation of that portion of the underlying contracts underwritten 
by each ceding company, which are in turn ceded to BHRG.  A range of reserve amounts as a result of changes in underlying 
assumptions is not prepared. 

Other Critical Accounting Policies 
Berkshire records as assets deferred charges with respect to liabilities assumed under retroactive reinsurance contracts. 
At  the  inception  of  these  contracts,  the  deferred  charges  represent  the  difference  between  the  consideration  received  and  the 
estimated ultimate liability for unpaid losses.  Deferred charges are amortized using the interest method over an estimate of the 
ultimate claim payment period and are reflected in earnings as a component of losses and loss expenses.  The deferred charge 
balances are adjusted periodically to reflect new projections of the amount and timing of loss payments.  Adjustments to these 
assumptions are applied retrospectively from the inception of the contract.  Unamortized deferred charges were $2.0 billion at 
December 31, 2006.  Significant changes in the amount and payment timing of estimated unpaid losses may have a significant 
effect on unamortized deferred charges and the amount of periodic amortization. 

Berkshire’s  Consolidated  Balance  Sheet  as  of  December  31,  2006  includes  goodwill  of  acquired  businesses  of 
approximately $32.2 billion.  A significant amount of judgment is required in performing goodwill impairment tests.  Such tests 
include periodically determining or reviewing the estimated fair value of Berkshire’s reporting units.  There are several methods 
of  estimating  a  reporting  unit’s  fair  value,  including  market  quotations,  asset  and  liability  fair  values  and  other  valuation 
techniques,  such  as  discounted  projected  future  net  earnings  and  multiples  of  earnings.    If  the  carrying  amount  of  a  reporting 
unit,  including  goodwill,  exceeds  the  estimated  fair  value,  then  individual  assets,  including  identifiable  intangible  assets,  and 
liabilities of the reporting unit are estimated at fair value.  The excess of the estimated fair value of the reporting unit over the 
estimated fair value of net assets would establish the implied value of goodwill.  The excess of the recorded amount of goodwill 
over the implied value is then charged to earnings as an impairment loss. 

Berkshire’s consolidated financial position reflects very significant amounts of invested assets.  A substantial portion 
of  these  assets  are  carried  at  fair  values  based  upon  current  market  quotations  and,  when  not  available,  based  upon  fair  value 
pricing  models.    Certain  of  Berkshire’s  fixed  maturity  securities  are  not  actively  traded  in  the  financial  markets.    Further, 
Berkshire’s  finance  businesses  maintain  significant  balances  of  finance  receivables,  which  are  carried  at  amortized  cost.  
Considerable judgment is required in determining the assumptions used in certain valuation models, including interest rate, loan 
prepayment  speed,  credit  risk  and  liquidity  risk  assumptions.    Significant  changes  in  these  assumptions  can  have  a  significant 
effect on carrying values. 

Information concerning recently issued accounting pronouncements which are not yet effective is included in Note 1(r) 
to the Consolidated Financial Statements.  Berkshire does not expect that the adoption of any of the recently issued accounting 
pronouncements will have a material effect on its financial condition. 

Market Risk Disclosures 

Berkshire’s  Consolidated  Balance  Sheets  include  a  substantial  amount  of  assets  and  liabilities  whose  fair  values  are 
subject  to  market  risks.   Berkshire’s significant market risks are primarily associated with interest rates, equity prices, foreign 
currency  exchange  rates  and  commodity  prices.    The  following  sections  address  the  significant  market  risks  associated  with 
Berkshire’s business activities. 

Interest Rate Risk 
Berkshire’s management prefers to invest in equity securities or to acquire entire businesses based upon the principles 
discussed in the following section on equity price risk.  When unable to do so, management may alternatively invest in bonds, 
loans  or  other  interest  rate  sensitive  instruments.    Berkshire’s  strategy  is  to  acquire  securities  that  are  attractively  priced  in 
relation to the perceived credit risk.  Management recognizes and accepts that losses may occur.  Further, Berkshire strives to 
maintain the highest credit ratings so that the cost of debt is minimized.  Berkshire utilizes derivative products, such as interest 
rate swaps, to manage interest rate risks on a limited basis. 

The  fair  values  of  Berkshire’s  fixed  maturity  investments  and  notes  payable  and  other  borrowings  will  fluctuate  in 
response to changes in market interest rates.  Increases and decreases in prevailing interest rates generally translate into decreases 
and increases in fair values of those instruments.  Additionally, fair values of interest rate sensitive instruments may be affected 
by  the  creditworthiness  of  the  issuer,  prepayment  options,  relative  values  of  alternative  investments,  the  liquidity  of  the 
instrument and other general market conditions.  Fixed interest rate investments may be more sensitive to interest rate changes 
than variable rate investments.

Interest Rate Risk (Continued) 

The following table summarizes the estimated effects of hypothetical increases and decreases in interest rates on assets 
and  liabilities  that  are  subject  to  interest  rate  risk.    It  is  assumed  that  the  changes  occur  immediately  and  uniformly  to  each 
category of instrument containing interest rate risk.  The hypothetical changes in market interest rates do not reflect what could 
be deemed best or worst case scenarios.  Variations in market interest rates could produce significant changes in the timing of 
repayments due to prepayment options available.  For these reasons, actual results might differ from those reflected in the table.

Equity Price Risk 

Strategically,  Berkshire  strives  to  invest  in  businesses  that  possess  excellent  economics,  with  able  and  honest 
management  and  at  sensible  prices.    Berkshire’s  management  prefers  to  invest  a  meaningful  amount  in  each  investee. 
Accordingly, Berkshire’s equity investments are generally concentrated in relatively few investees.  At December 31, 2006, 54% 
of the total fair value of equity investments was concentrated in four investees. 

Berkshire’s  preferred  strategy  is  to  hold  equity  investments  for  very  long  periods  of  time.  Thus,  Berkshire’s 
management  is  not  troubled  by  short-term  equity  price  volatility  with  respect  to  its  investments  provided  that  the  underlying 
business,  economic  and  management  characteristics  of  the  investees  remain  favorable.    Berkshire  strives  to  maintain  above 
average levels of shareholder capital to provide a margin of safety against short-term equity price volatility. 

The  carrying  values  of  investments  subject  to  equity  price  risk  are,  in  almost  all  instances,  based  on  quoted  market 
prices  as  of  the  balance  sheet  dates.    Market  prices  are  subject  to  fluctuation  and,  consequently,  the  amount  realized  in  the 
subsequent sale of an investment may significantly differ from the reported market value.  Fluctuation in the market price of a 
security  may  result  from  perceived  changes  in  the  underlying  economic  characteristics  of  the  investee,  the  relative  price  of 
alternative investments and general market conditions.  Furthermore, amounts realized in the sale of a particular security may be 
affected by the relative quantity of the security being sold. 

The table which follows summarizes Berkshire’s equity price risk as of December 31, 2006 and 2005 and shows the 
effects of a hypothetical 30% increase and a 30% decrease in market prices as of those dates.  The selected hypothetical change 
does not reflect what could be considered the best or worst case scenarios.  Indeed, results could be far worse due both to the 
nature of equity markets and the aforementioned concentrations existing in Berkshire’s equity investment portfolio.  Dollars are

Management’s Discussion (Continued) 

Equity Price Risk (Continued) 

Berkshire  is  also  subject  to  equity  price  risk  with  respect  to  certain  long  duration  equity  index  option  contracts. 
Berkshire’s  maximum  exposure  with  respect  to  such  contracts  was  approximately  $21  billion  and  $14  billion  at  
December 31, 2006 and 2005, respectively.  These contracts generally expire 15 to 20 years from inception and they may not be 
settled before their respective expiration dates.  The contracts have been written on four major equity indexes including three that 
are foreign. While Berkshire’s ultimate potential loss with respect to these contracts is directly correlated to the movement of the 
underlying  stock  index  between  contract  inception  date  and  expiration,  the  change  in  fair  value  from  current  changes  in  the 
indices do not produce a proportional change in the estimated fair value of the contracts.  Other factors (such as expected future 
interest  rates,  dividend  rates  and  the  remaining  duration  of  the  contract  as  well  as  the  general  market  assumptions)  affect  the 
estimates  of  fair  value  reflected  in  the  financial  statements.    Thus,  if  the  underlying  indices  declined  30%  immediately,  and 
absent changes in other factors, Berkshire estimates that it could incur a non-cash pre-tax loss of approximately $2 billion from 
the change in the estimated fair value of open contracts as of December 31, 2006. 

Foreign Currency Risk 

Market  risks  associated  with  changes  in  foreign  currency  exchange  rates  are  currently  concentrated  in  a  portfolio  of 
long  duration  equity  index  option  contracts  on  foreign  equity  indexes.    In  2005,  Berkshire  also  had  significant  exposure  to 
foreign currency risk from a portfolio of short duration forward contracts.  The aggregate notional value of forward contracts was 
approximately $1 billion as of December 31, 2006 compared to approximately $13.8 billion as of December 31, 2005. 

The following table summarizes the outstanding derivatives contracts as of December 31, 2006 and 2005 with foreign 
currency  risk  and  shows  the  estimated  changes  in  values  of  the  contracts  assuming  changes  in  the  underlying  exchange  rates 
applied immediately and uniformly across all currencies.  The changes in value do not necessarily reflect the best or worst case 
scenarios and actual results may differ.  Dollars are in millions.

Berkshire, through its ownership of MidAmerican, is subject to commodity risk.  Exposures include variations in the 
price of wholesale electricity that is purchased and sold, fuel costs to generate electricity, and natural gas supply for regulated 
retail  gas  customers.    Electricity  and  natural  gas  prices  are  subject  to  wide  price swings as demand responds to, among many 
other items, changing weather, limited storage, transmission and transportation constraints, and lack of alternative supplies from 
other  areas.    To  mitigate  a  portion  of  the  risk,  MidAmerican  uses  derivative  instruments, including forwards, futures, options, 
swaps and other over-the-counter agreements, to effectively secure future supply or sell future production at fixed prices.  The 
settled cost of these contracts is generally recovered from customers in regulated rates.  Accordingly, the net unrealized gains 
and losses associated with interim price movements on such contracts are recorded as regulatory assets or liabilities.  Financial 
results may be negatively impacted if the costs of wholesale electricity, fuel and or natural gas are higher than what is permitted 
to be recovered in rates.  MidAmerican also uses futures, options and swap agreements to economically hedge gas and electric 
commodity  prices  for  physical  delivery  to  non-regulated  customers.    MidAmerican  does  not  engage  in  a  material  amount  of 
proprietary trading activities. 

The table that follows summarizes Berkshire’s commodity risk on energy derivative contracts as of December 31, 2006 
and shows the effects of a hypothetical 10% increase and a 10% decrease in forward market prices by the expected volumes for 
these contracts as of that date.  The selected hypothetical change does not reflect what could be considered the best or worst case

Management’s Report on Internal Control Over Financial Reporting 

Management of Berkshire Hathaway Inc. is responsible for establishing and maintaining adequate internal control over financial reporting, 
as such term is defined in the Securities Exchange Act of 1934 Rule 13a-15(f).  Under the supervision and with the participation of our 
management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of 
the Company’s internal control over financial reporting as of December 31, 2006 as required by the Securities Exchange Act of 1934 Rule 
13a-15(c).  In making this assessment, we used the criteria set forth in the framework in Internal Control – Integrated Framework issued 
by the Committee of Sponsoring Organizations of the Treadway Commission.  Based on our evaluation under the framework in Internal 
Control  –  Integrated  Framework,  our  management  concluded  that  our  internal  control  over  financial  reporting  was  effective  as  of 
December 31, 2006. 

Our  management’s  assessment  of  the  effectiveness  of  our  internal  control  over  financial  reporting  as  of  December  31,  2006  has  been 
audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their report which appears below. 

Berkshire Hathaway Inc. 
February 26, 2007 

Report of Independent Registered Public Accounting Firm 

To the Board of Directors and Shareholders of 
Berkshire Hathaway Inc. 

We  have  audited  management’s  assessment,  included  in  the  accompanying,  Management’s  Reports  on  Internal  Control  Over  Financial 
Reporting, that Berkshire Hathaway Inc. and subsidiaries (the “Company”) maintained effective internal control over financial reporting as 
of  December  31,  2006,  based  on  criteria  established  in  Internal  Control-Integrated  Framework  issued  by  the  Committee  of  Sponsoring 
Organizations  of  the  Treadway  Commission.  The  Company’s  management  is  responsible  for  maintaining  effective  internal  control  over 
financial reporting and for its assessment of the effectiveness of internal control over financial reporting.  Our responsibility is to express an 
opinion on management’s assessment and an opinion on the effectiveness of the Company’s internal control over financial reporting based 
on our audit. 

We  conducted  our  audit  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board  (United  States).    Those 
standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial 
reporting  was  maintained  in  all  material  respects.    Our  audit  included  obtaining  an  understanding  of  internal  control  over  financial 
reporting,  evaluating  management’s  assessment,  testing  and  evaluating  the  design  and  operating  effectiveness  of  internal  control,  and 
performing such other procedures as we considered necessary in the circumstances.  We believe that our audit provides a reasonable basis 
for our opinions. 

A  company’s  internal  control  over  financial  reporting  is  a  process  designed  by,  or  under  the  supervision  of,  the  company’s  principal 
executive  and  principal  financial  officers,  or  persons  performing  similar  functions,  and  effected  by  the  company’s  board  of  directors, 
management,  and  other  personnel  to  provide  reasonable  assurance  regarding  the  reliability  of  financial  reporting  and  the  preparation  of 
financial statements for external purposes in accordance with generally accepted accounting principles.  A company’s internal control over 
financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately 
and  fairly  reflect  the  transactions  and  dispositions  of  the  assets  of  the  company;  (2)  provide  reasonable  assurance  that  transactions  are 
recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that 
receipts  and  expenditures  of  the  company  are  being  made  only  in  accordance  with  authorizations  of  management  and  directors  of  the 
company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of 
the company’s assets that could have a material effect on the financial statements. 

Because  of  the  inherent  limitations  of  internal  control  over  financial  reporting,  including  the  possibility  of  collusion  or  improper 
management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis.  Also, 
projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that 
the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may 
deteriorate.  

In our opinion, management’s assessment that the Company maintained effective internal control over financial reporting as of December 
31, 2006, is fairly stated, in all material respects, based on the criteria established in Internal Control—Integrated Framework issued by the 
Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission.    Also  in  our  opinion,  the  Company  maintained,  in  all  material 
respects, effective internal control over financial reporting as of December 31, 2006, based on the criteria established in Internal Control—
Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. 

We  have  also  audited,  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board  (United  States),  the 
consolidated financial statements as of and for the year ended December 31, 2006 of the Company and our report dated February 28, 2007 
expressed  an  unqualified  opinion  on  those  financial  statements  with  an  explanatory  paragraph  relating  to  the  change  in  the  Company’s 
accounting for pension and other postretirement benefits to conform to Statement of Financial Accounting Standards No. 158, Employers’ 
Accounting for Defined Benefit Pension and Other Postretirement Plans, an amendment of FASB Statements No. 87, 88, 106, and 132(R).

In  June  1996,  Berkshire’s  Chairman,  Warren  E.  Buffett,  issued  a  booklet  entitled  “An  Owner’s  Manual”  to 
Berkshire’s Class A and Class B shareholders.  The purpose of the manual was to explain Berkshire’s broad economic principles 
of operation.  An updated version is reproduced on this and the following four pages. 

____________________________________________________________________ 

OWNER-RELATED BUSINESS PRINCIPLES 

At the time of the Blue Chip merger in 1983, I set down 13 owner-related business principles that I thought would help 
new shareholders understand our managerial approach.  As is appropriate for “principles,” all 13 remain alive and well today, 
and they are stated here in italics. 

1. 

Although our form is corporate, our attitude is partnership. Charlie Munger and I think of our shareholders as owner-
partners, and of ourselves as managing partners. (Because of the size of our shareholdings we are also, for better or 
worse,  controlling  partners.)    We  do  not  view  the  company  itself  as  the  ultimate  owner  of  our  business  assets  but 
instead view the company as a conduit through which our shareholders own the assets. 

Charlie and I hope that you do not think of yourself as merely owning a piece of paper whose price wiggles around 
daily and that is a candidate for sale when some economic or political event makes you nervous. We hope you instead 
visualize  yourself  as  a  part  owner  of  a  business  that  you  expect  to  stay  with  indefinitely,  much as you might if you 
owned a farm or apartment house in partnership with members of your family.  For our part, we do not view Berkshire 
shareholders as faceless members of an ever-shifting crowd, but rather as co-venturers who have entrusted their funds 
to us for what may well turn out to be the remainder of their lives. 

The  evidence  suggests  that  most  Berkshire  shareholders  have  indeed  embraced  this  long-term  partnership  concept.  
The annual percentage turnover in Berkshire’s shares is a small fraction of that occurring in the stocks of other major 
American corporations, even when the shares I own are excluded from the calculation. 

In  effect,  our  shareholders  behave  in  respect  to  their  Berkshire  stock  much  as  Berkshire  itself  behaves  in  respect  to 
companies  in  which  it  has  an  investment.    As  owners  of,  say,  Coca-Cola  or  American  Express  shares,  we  think  of 
Berkshire as being a non-managing partner in two extraordinary businesses, in which we measure our success by the 
long-term progress of the companies rather than by the month-to-month movements of their stocks.  In fact, we would 
not care in the least if several years went by in which there was no trading, or quotation of prices, in the stocks of those 
companies.  If  we  have  good  long-term  expectations,  short-term  price  changes  are  meaningless  for  us  except  to  the 
extent they offer us an opportunity to increase our ownership at an attractive price. 

2. 

In line with Berkshire’s owner-orientation, most of our directors have a major portion of their net worth invested in the 
company.  We eat our own cooking. 

Charlie’s  family  has  90%  or  more  of  its  net  worth  in  Berkshire  shares;  I  have  about  99%.  In  addition,  many  of  my 
relatives — my sisters and cousins, for example — keep a huge portion of their net worth in Berkshire stock. 

Charlie  and  I  feel  totally  comfortable  with  this  eggs-in-one-basket  situation  because  Berkshire  itself  owns  a  wide 
variety of truly extraordinary businesses. Indeed, we believe that Berkshire is close to being unique in the quality and 
diversity of the businesses in which it owns either a controlling interest or a minority interest of significance. 

Charlie and I cannot promise you results.  But we can guarantee that your financial fortunes will move in lockstep with 
ours for whatever period of time you elect to be our partner.  We have no interest in large salaries or options or other 
means of gaining an “edge” over you.  We want to make money only when our partners do and in exactly the same 
proportion.  Moreover, when I do something dumb, I want you to be able to derive some solace from the fact that my 
financial suffering is proportional to yours.

4. 

Our  long-term  economic  goal  (subject  to  some  qualifications  mentioned  later)  is  to  maximize  Berkshire’s  average 
annual rate of gain in intrinsic business value on a per-share basis. We do not measure the economic significance or 
performance  of  Berkshire  by  its  size;  we  measure  by  per-share  progress.    We  are  certain  that  the  rate  of  per-share 
progress will diminish in the future — a greatly enlarged capital base will see to that.  But we will be disappointed if 
our rate does not exceed that of the average large American corporation. 

Our preference would be to reach our goal by directly owning a diversified group of businesses that generate cash and 
consistently earn above-average returns on capital.  Our second choice is to own parts of similar businesses, attained 
primarily through purchases of marketable common stocks by our insurance subsidiaries.  The price and availability of 
businesses and the need for insurance capital determine any given year’s capital allocation.

In recent years we have made a number of acquisitions.  Though there will be dry years, we expect to make many more 
in the decades to come, and our hope is that they will be large.  If these purchases approach the quality of those we 
have made in the past, Berkshire will be well served. 

The challenge for us is to generate ideas as rapidly as we generate cash. In this respect, a depressed stock market is 
likely to present us with significant advantages.  For one thing, it tends to reduce the prices at which entire companies 
become available for purchase.  Second, a depressed market makes it easier for our insurance companies to buy small 
pieces  of  wonderful  businesses  —  including  additional  pieces  of  businesses  we  already  own  —  at  attractive  prices.  
And  third,  some  of  those  same  wonderful  businesses,  such  as  Coca-Cola,  are  consistent  buyers  of  their  own  shares, 
which means that they, and we, gain from the cheaper prices at which they can buy. 

Overall, Berkshire and its long-term shareholders benefit from a sinking stock market much as a regular purchaser of 
food  benefits  from  declining  food  prices.    So  when  the  market  plummets  —  as  it  will  from  time  to  time  —  neither 
panic nor mourn.  It’s good news for Berkshire. 

Because  of  our  two-pronged  approach  to  business  ownership  and  because  of  the  limitations  of  conventional 
accounting, consolidated reported earnings may reveal relatively little about our true economic performance.  Charlie 
and I, both as owners and managers, virtually ignore such consolidated numbers.  However, we will also report to you 
the earnings of each major business we control, numbers we consider of great importance. These figures, along with 
other information we will supply about the individual businesses, should generally aid you in making judgments about 
them. 

To state things simply, we try to give you in the annual report the numbers and other information that really matter.  
Charlie and I pay a great deal of attention to how well our businesses are doing, and we also work to understand the 
environment in which each business is operating. For example, is one of our businesses enjoying an industry tailwind 
or is it facing a headwind?  Charlie and I need to know exactly which situation prevails and to adjust our expectations 
accordingly. We will also pass along our conclusions to you. 

Over  time,  the  large  majority  of  our  businesses  have  exceeded  our  expectations.  But  sometimes  we  have 
disappointments,  and  we  will  try  to  be  as  candid  in  informing  you  about  those  as  we  are  in  describing  the  happier 
experiences. When we use unconventional measures to chart our progress — for instance, you will be reading in our 
annual reports about insurance “float” — we will try to explain these concepts and why we regard them as important. 
In other words, we believe in telling you how we think so that you can evaluate not only Berkshire’s businesses but 
also assess our approach to management and capital allocation. 

Accounting consequences do not influence our operating or capital-allocation decisions.  When acquisition costs are 
similar, we much prefer to purchase $2 of earnings that is not reportable by us under standard accounting principles 
than  to  purchase  $1  of  earnings  that  is  reportable.    This  is  precisely  the  choice  that  often  faces  us  since  entire 
businesses  (whose  earnings  will  be  fully  reportable)  frequently  sell  for  double  the  pro-rata  price  of  small  portions 
(whose earnings will be largely unreportable).  In aggregate and over time, we expect the unreported earnings to be 
fully reflected in our intrinsic business value through capital gains. 

We have found over time that the undistributed earnings of our investees, in aggregate, have been fully as beneficial to 
Berkshire as if they had been distributed to us (and therefore had been included in the earnings we officially report).  
This pleasant result has occurred because most of our investees are engaged in truly outstanding businesses that can 
often employ incremental capital to great advantage, either by putting it to work in their businesses or by repurchasing 
their shares.  Obviously, every capital decision that our investees have made has not benefitted us as shareholders, but 
overall we have garnered far more than a dollar of value for each dollar they have retained.  We consequently regard 
look-through earnings as realistically portraying our yearly gain from operations. 

We use debt sparingly and, when we do borrow, we attempt to structure our loans on a long-term fixed-rate basis. We 
will reject interesting opportunities rather than over-leverage our balance sheet. This conservatism has penalized our 
results but it is the only behavior that leaves us comfortable, considering our fiduciary obligations to policyholders, 
lenders and the many equity holders who have committed unusually large portions of their net worth to our care. (As 
one of the Indianapolis “500” winners said:  “To finish first, you must first finish.”) 

The financial calculus that Charlie and I employ would never permit our trading a good night’s sleep for a shot at a few 
extra percentage points of return.  I’ve never believed in risking what my family and friends have and need in order to 
pursue what they don’t have and don’t need. 

Besides, Berkshire has access to two low-cost, non-perilous sources of leverage that allow us to safely own far more 
assets  than  our  equity capital alone would permit:  deferred taxes and “float,” the funds of others that our insurance 
business  holds  because  it  receives  premiums  before  needing  to  pay  out  losses.    Both  of  these  funding  sources  have 
grown rapidly and now total about $69 billion.

Better yet, this funding to date has often been cost-free.  Deferred tax liabilities bear no interest.  And as long as we 
can break even in our insurance underwriting the cost of the float developed from that operation is zero.  Neither item, 
of course, is equity; these are real liabilities. But they are liabilities without covenants or due dates attached to them.  
In effect, they give us the benefit of debt — an ability to have more assets working for us — but saddle us with none of 
its drawbacks. 

Of  course,  there  is  no  guarantee  that  we  can  obtain  our  float  in  the  future  at  no  cost.  But  we  feel  our  chances  of 
attaining that goal are as good as those of anyone in the insurance business.  Not only have we reached the goal in the 
past (despite a number of important mistakes by your Chairman), our 1996 acquisition of GEICO, materially improved 
our prospects for getting there in the future. 

A  managerial  “wish  list”  will  not  be  filled  at  shareholder  expense.    We  will  not  diversify  by  purchasing  entire 
businesses at control prices that ignore long-term economic consequences to our shareholders.  We will only do with 
your  money  what  we  would  do  with  our  own,  weighing  fully  the  values  you  can  obtain  by  diversifying  your  own 
portfolios through direct purchases in the stock market. 

Charlie and I are interested only in acquisitions that we believe will raise the per-share intrinsic value of Berkshire’s 
stock.  The size of our paychecks or our offices will never be related to the size of Berkshire’s balance sheet. 

We feel noble intentions should be checked periodically against results.  We test the wisdom of retaining earnings by 
assessing whether retention, over time, delivers shareholders at least $1 of market value for each $1 retained.  To date, 
this  test  has  been  met.   We will continue to apply it on a five-year rolling basis. As our net worth grows, it is more 
difficult to use retained earnings wisely. 

We continue to pass the test, but the challenges of doing so have grown more difficult.  If we reach the point that we 
can’t create extra value by retaining earnings, we will pay them out and let our shareholders deploy the funds. 

We will issue common stock only when we receive as much in business value as we give.  This rule applies to all forms 
of  issuance  —  not  only  mergers  or  public  stock  offerings,  but  stock-for-debt  swaps,  stock  options,  and  convertible 
securities as well. We will not sell small portions of your company — and that is what the issuance of shares amounts 
to — on a basis inconsistent with the value of the entire enterprise. 

When  we  sold  the  Class  B  shares  in  1996,  we  stated  that  Berkshire  stock  was  not  undervalued  —  and  some  people 
found that shocking.  That reaction was not well-founded. Shock should have registered instead had we issued shares 
when  our  stock  was  undervalued.  Managements  that  say  or  imply  during  a  public  offering  that  their  stock  is 
undervalued  are  usually  being  economical  with  the  truth  or  uneconomical  with  their  existing  shareholders’  money:  
Owners unfairly lose if their managers deliberately sell assets for 80¢ that in fact are worth $1. We didn’t commit that 
kind of crime in our offering of Class B shares and we never will.  (We did not, however, say at the time of the sale 
that our stock was overvalued, though many media have reported that we did.) 

You  should  be  fully  aware  of  one  attitude  Charlie  and  I  share  that  hurts  our  financial  performance:    Regardless  of 
price, we have no interest at all in selling any good businesses that Berkshire owns. We are also very reluctant to sell 
sub-par businesses as long as we expect them to generate at least some cash and as long as we feel good about their 
managers  and  labor  relations.  We  hope  not  to  repeat  the  capital-allocation  mistakes  that  led  us  into  such  sub-par 
businesses.  And  we  react  with  great  caution  to  suggestions  that  our  poor  businesses  can  be  restored  to  satisfactory 
profitability by major capital expenditures. (The projections will be dazzling and the advocates sincere, but, in the end, 
major  additional  investment  in  a  terrible  industry  usually  is  about  as  rewarding  as  struggling  in  quicksand.)  
Nevertheless, gin rummy managerial behavior (discard your least promising business at each turn) is not our style. We 
would rather have our overall results penalized a bit than engage in that kind of behavior. 

We continue to avoid gin rummy behavior.  True, we closed our textile business in the mid-1980’s after 20 years of 
struggling with it, but only because we felt it was doomed to run never-ending operating losses. We have not, however, 
given thought to selling operations that would command very fancy prices nor have we dumped our laggards, though 
we focus hard on curing the problems that cause them to lag. 

We will be candid in our reporting to you, emphasizing the pluses and minuses important in appraising business value. 
Our guideline is to tell you the business facts that we would want to know if our positions were reversed. We owe you 
no less. Moreover, as a company with a major communications business, it would be inexcusable for us to apply lesser 
standards of accuracy, balance and incisiveness when reporting on ourselves than we would expect our news people to 
apply when reporting on others. We also believe candor benefits us as managers:  The CEO who misleads others in 
public may eventually mislead himself in private. 

At Berkshire you will find no “big bath” accounting maneuvers or restructurings nor any “smoothing” of quarterly or 
annual results. We will always tell you how many strokes we have taken on each hole and never play around with the 
scorecard. When the numbers are a very rough “guesstimate,” as they necessarily must be in insurance reserving, we 
will try to be both consistent and conservative in our approach. 

76 

 
 
 
 
 
 
 
 
 
We will be communicating with you in several ways. Through the annual report, I try to give all shareholders as much 
value-defining information as can be conveyed in a document kept to reasonable length. We also try to convey a liberal 
quantity of condensed but important information in the quarterly reports we post on the internet, though I don’t write 
those  (one  recital  a  year  is  enough).  Still  another  important  occasion  for  communication  is  our  Annual  Meeting,  at 
which Charlie and I are delighted to spend five hours or more answering questions about Berkshire. But there is one 
way we can’t communicate:  on a one-on-one basis. That isn’t feasible given Berkshire’s many thousands of owners. 

In all of our communications, we try to make sure that no single shareholder gets an edge:  We do not follow the usual 
practice of giving earnings “guidance” or other information of value to analysts or large shareholders. Our goal is to 
have all of our owners updated at the same time. 

13. 

Despite our policy of candor, we will discuss our activities in marketable securities only to the extent legally required. 
Good investment ideas are rare, valuable and subject to competitive appropriation just as good product or business 
acquisition  ideas  are.  Therefore  we  normally  will  not  talk  about  our  investment  ideas.  This  ban  extends  even  to 
securities we have sold (because we may purchase them again) and to stocks we are incorrectly rumored to be buying. 
If we deny those reports but say “no comment” on other occasions, the no-comments become confirmation. 

Though  we  continue  to  be  unwilling  to  talk  about  specific  stocks,  we  freely  discuss  our  business  and  investment 
philosophy. I benefitted enormously from the intellectual generosity of Ben Graham, the greatest teacher in the history 
of  finance,  and  I  believe  it  appropriate  to  pass  along  what  I  learned  from  him,  even  if  that  creates  new  and  able 
investment competitors for Berkshire just as Ben’s teachings did for him. 

TWO ADDED PRINCIPLES 

14.  To the extent possible, we would like each Berkshire shareholder to record a gain or loss in market value during his period 
of  ownership  that  is  proportional  to  the  gain  or  loss  in  per-share  intrinsic  value  recorded  by  the  company  during  that 
holding  period.  For  this  to  come  about,  the  relationship  between  the  intrinsic  value  and  the  market  price  of  a  Berkshire 
share would need to remain constant, and by our preferences at 1-to-1. As that implies, we would rather see Berkshire’s 
stock price at a fair level than a high level. Obviously, Charlie and I can’t control Berkshire’s price. But by our policies 
and communications, we can encourage informed, rational behavior by owners that, in turn, will tend to produce a stock 
price  that  is  also  rational.  Our  it’s-as-bad-to-be-overvalued-as-to-be-undervalued  approach  may  disappoint  some 
shareholders. We believe, however, that it affords Berkshire the best prospect of attracting long-term investors who seek to 
profit from the progress of the company rather than from the investment mistakes of their partners. 

15.  We regularly compare the gain in Berkshire’s per-share book value to the performance of the S&P 500.  Over time, we hope 
to outpace this yardstick.  Otherwise, why do our investors need us?  The measurement, however, has certain shortcomings 
that are described in the next section.  Moreover, it now is less meaningful on a year-to-year basis than was formerly the 
case.  That is because our equity holdings, whose value tends to move with the S&P 500, are a far smaller portion of our net 
worth than they were in earlier years.  Additionally, gains in the S&P stocks are counted in full in calculating that index, 
whereas gains in Berkshire’s equity holdings are counted at 65% because of the federal tax we incur.  We, therefore, expect 
to outperform the S&P in lackluster years for the stock market and underperform when the market has a strong year. 

INTRINSIC VALUE 

Now let’s focus on a term that I mentioned earlier and that you will encounter in future annual reports. 

Intrinsic  value  is  an  all-important  concept  that  offers  the  only  logical  approach  to  evaluating  the  relative  attractiveness  of 
investments and businesses. Intrinsic value can be defined simply:  It is the discounted value of the cash that can be taken out of a business 
during its remaining life. 

The calculation of intrinsic value, though, is not so simple. As our definition suggests, intrinsic value is an estimate rather than a 
precise figure, and it is additionally an estimate that must be changed if interest rates move or forecasts of future cash flows are revised. 
Two people looking at the same set of facts, moreover — and this would apply even to Charlie and me — will almost inevitably come up 
with  at  least  slightly  different  intrinsic  value  figures.  That  is  one  reason  we  never  give  you  our  estimates  of  intrinsic  value.  What  our 
annual reports do supply, though, are the facts that we ourselves use to calculate this value. 

Meanwhile,  we  regularly  report  our  per-share  book  value,  an  easily  calculable  number,  though  one  of  limited  use.  The 
limitations  do  not  arise  from  our  holdings  of  marketable  securities,  which  are  carried  on  our  books  at  their  current  prices.  Rather  the 
inadequacies of book value have to do with the companies we control, whose values as stated on our books may be far different from their 
intrinsic values. 

The disparity can go in either direction. For example, in 1964 we could state with certitude that Berkshire’s per-share book value 
was $19.46. However, that figure considerably overstated the company’s intrinsic value, since all of the company’s resources were tied up 
in  a  sub-profitable  textile  business.  Our  textile  assets  had  neither  going-concern  nor  liquidation  values  equal  to  their  carrying  values. 
Today, however, Berkshire’s situation is reversed:  Now, our book value far understates Berkshire’s intrinsic value, a point true because 
many of the businesses we control are worth much more than their carrying value. 

77 

 
 
 
 
 
 
 
 
 
 
Inadequate though they are in telling the story, we give you Berkshire’s book-value figures because they today serve as a rough, 
albeit significantly understated, tracking measure for Berkshire’s intrinsic value. In other words, the percentage change in book value in 
any given year is likely to be reasonably close to that year’s change in intrinsic value. 

You can gain some insight into the differences between book value and intrinsic value by looking at one form of investment, a 
college education. Think of the education’s cost as its “book value.”  If this cost is to be accurate, it should include the earnings that were 
foregone by the student because he chose college rather than a job. 

For this exercise, we will ignore the important non-economic benefits of an education and focus strictly on its economic value. 
First, we must estimate the earnings that the graduate will receive over his lifetime and subtract from that figure an estimate of what he 
would have earned had he lacked his education. That gives us an excess earnings figure, which must then be discounted, at an appropriate 
interest rate, back to graduation day. The dollar result equals the intrinsic economic value of the education. 

Some graduates will find that the book value of their education exceeds its intrinsic value, which means that whoever paid for the 
education  didn’t  get  his  money’s  worth.  In  other  cases,  the  intrinsic  value  of  an  education  will  far  exceed  its  book  value,  a  result  that 
proves capital was wisely deployed. In all cases, what is clear is that book value is meaningless as an indicator of intrinsic value. 

THE MANAGING OF BERKSHIRE 

I think it’s appropriate that I conclude with a discussion of Berkshire’s management, today and in the future. As our first owner-
related principle tells you, Charlie and I are the managing partners of Berkshire. But we subcontract all of the heavy lifting in this business 
to the managers of our subsidiaries. In fact, we delegate almost to the point of abdication: Though Berkshire has about 217,000 employees, 
only 19 of these are at headquarters. 

Charlie  and  I  mainly  attend  to  capital  allocation  and  the  care  and  feeding  of  our  key  managers.  Most  of  these  managers  are 
happiest when they are left alone to run their businesses, and that is customarily just how we leave them. That puts them in charge of all 
operating decisions and of dispatching the excess cash they generate to headquarters. By sending it to us, they don’t get diverted by the 
various  enticements  that  would  come  their  way  were  they  responsible  for  deploying  the  cash  their  businesses  throw  off.  Furthermore, 
Charlie and I are exposed to a much wider range of possibilities for investing these funds than any of our managers could find in his or her 
own industry. 

Most of our managers are independently wealthy, and it’s therefore up to us to create a climate that encourages them to choose 
working with Berkshire over golfing or fishing. This leaves us needing to treat them fairly and in the manner that we would wish to be 
treated if our positions were reversed. 

As  for  the  allocation  of  capital,  that’s  an  activity  both  Charlie  and  I  enjoy  and  in  which  we  have  acquired  some  useful 
experience.  In  a  general  sense,  grey  hair  doesn’t  hurt  on  this  playing  field:    You  don’t  need  good  hand-eye  coordination  or  well-toned 
muscles to push money around (thank heavens). As long as our minds continue to function effectively, Charlie and I can keep on doing our 
jobs pretty much as we have in the past. 

On my death, Berkshire’s ownership picture will change but not in a disruptive way:  None of my stock will have to be sold to 
take care of the cash bequests I have made or for taxes.  Other assets of mine will take care of these requirements.  All Berkshire shares 
will be left to foundations that will likely receive the stock in roughly equal installments over a dozen or so years. 

At my death, the Buffett family will not be involved in managing the business but, as very substantial shareholders, will help in 
picking  and  overseeing  the  managers  who  do.  Just  who  those  managers  will  be,  of  course,  depends  on  the  date  of  my  death.  But  I  can 
anticipate what the management structure will be:  Essentially my job will be split into two parts, with one executive becoming responsible 
for investments and another, who will be CEO, for operations. If the acquisition of new businesses is in prospect, the two will cooperate in 
making the decisions needed, subject, of course, to board approval. We will continue to have an extraordinarily shareholder-minded board, 
one whose interests are solidly aligned with yours. 

Were  we  to  need  the  management  structure  I  have  just  described  on  an  immediate  basis,  our  directors  know  who  I  would 

recommend for both posts.  All candidates currently work for Berkshire and are people in whom I have total confidence. 

I will continue to keep the directors posted on the succession issue.  Since Berkshire stock will make up virtually my entire estate 
and will account for a similar portion of the assets of various foundations for a considerable period after my death, you can be sure that the 
directors  and  I  have  thought  through  the  succession  question  carefully  and  that  we  are  well  prepared.  You  can  be  equally  sure  that  the 
principles  we  have  employed  to  date  in  running  Berkshire  will  continue  to  guide  the  managers  who  succeed  me  and that our unusually 
strong and well-defined culture will remain intact. 

Lest we end on a morbid note, I also want to assure you that I have never felt better. I love running Berkshire, and if enjoying 

life promotes longevity, Methuselah’s record is in jeopardy.
