Charlie Munger – The Architect of Berkshire Hathaway  
Charlie Munger died on November 28, just 33 days before his 100th birthday. 
Though  born  and  raised  in  Omaha,  he  spent  80%  of  his  life  domiciled 
elsewhere. Consequently, it was not until 1959 when he was 35 that I first met him. 
In 1962, he decided that he should take up money management. 
Three years later he told me – correctly! – that I had made a dumb decision in 
buying control of Berkshire. But, he assured me, since I had already made the move, 
he would tell me how to correct my mistake. 
In  what  I  next  relate,  bear  in  mind  that  Charlie  and  his  family  did  not  have  a 
dime invested in the small investing partnership that I was then managing and whose 
money I had used for the Berkshire purchase. Moreover, neither of us expected that 
Charlie would ever own a share of Berkshire stock. 
Nevertheless,  Charlie,  in  1965,  promptly  advised  me:  “Warren,  forget  about 
ever buying another company like Berkshire. But now that you control Berkshire, add 
to it wonderful businesses purchased at fair prices and give up buying fair businesses 
at wonderful prices. In other words, abandon everything you learned from your hero, 
Ben Graham. It works but only when practiced at small scale.” With much back-sliding 
I subsequently followed his instructions. 
Many  years  later,  Charlie  became  my  partner  in  running  Berkshire  and, 
repeatedly, jerked me back to sanity when my old habits surfaced. Until his death, he 
continued  in  this  role  and  together  we,  along  with  those  who  early  on  invested  with 
us, ended up far better off than Charlie and I had ever dreamed possible. 
In  reality,  Charlie  was  the  “architect”  of  the  present  Berkshire,  and  I  acted  as 
the “general contractor” to carry out the day-by-day construction of his vision. 
Charlie  never  sought  to  take  credit  for  his  role  as  creator  but  instead  let  me 
take the bows and receive the accolades. In a way his relationship with me was part 
older  brother,  part  loving  father.  Even  when  he  knew  he  was  right,  he  gave  me  the 
reins, and when I blundered he never – never –reminded me of my mistake. 
In  the  physical  world,  great  buildings  are  linked  to  their  architect  while  those 
who had poured the concrete or installed the windows are soon forgotten. Berkshire 
has become a great company. Though I have long been in charge of the construction 
crew; Charlie should forever be credited with being the architect.

BERKSHIRE HATHAWAY INC. 
To the Shareholders of Berkshire Hathaway Inc.: 
Berkshire  has  more  than  three  million  shareholder  accounts.  I  am  charged  with  writing  a 
letter  every  year  that  will  be  useful  to  this  diverse  and  ever-changing  group  of  owners,  many  of 
whom wish to learn more about their investment. 
Charlie  Munger,  for  decades  my  partner  in  managing  Berkshire,  viewed  this  obligation 
identically and would expect me to communicate with you this year in the regular manner. He and 
I were of one mind regarding our responsibilities to Berkshire shareholders. 
* * * * * * * * * * * * 
Writers find it useful to picture the reader they seek, and often they are hoping to attract a 
mass  audience.  At  Berkshire,  we  have  a  more  limited  target:  investors  who  trust  Berkshire  with 
their savings without any expectation of resale (resembling in attitude people who save in order to 
buy a farm or rental property rather than people who prefer using their excess funds to purchase 
lottery tickets or “hot” stocks). 
Over the years, Berkshire has attracted an unusual number of such “lifetime” shareholders 
and their heirs. We cherish their presence and believe they are entitled to hear every year both the 
good and bad news, delivered  directly  from their CEO and not from an investor-relations  officer 
or communications consultant forever serving up optimism and syrupy mush. 
In visualizing the owners that Berkshire seeks, I am lucky to have the perfect mental model, 
my sister, Bertie. Let me introduce her. 
For  openers,  Bertie  is  smart,  wise  and  likes  to  challenge  my  thinking.  We  have  never, 
however, had a shouting match or anything close to a ruptured relationship. We never will. 
Furthermore, Bertie, and her three daughters as well, have a large portion of their savings 
in Berkshire shares. Their ownership spans decades, and every year Bertie will read what I have 
to say. My job is to anticipate her questions and give her honest answers. 
3 
Bertie,  like  most  of  you,  understands  many  accounting  terms,  but  she  is  not  ready  for  a 
CPA  exam.  She  follows  business  news  –  reading  four  newspapers  daily  –  but  doesn’t  consider 
herself  an  economic  expert.  She  is  sensible  –  very  sensible  –  instinctively  knowing  that  pundits 
should always  be  ignored.  After  all,  if  she could  reliably  predict  tomorrow’s winners, would she 
freely  share  her  valuable  insights  and  thereby  increase  competitive  buying?  That  would  be  like 
finding gold and then handing a map to the neighbors showing its location. 
Bertie understands the power – for good or bad – of incentives, the weaknesses of humans, 
the  “tells”  that  can  be  recognized  when  observing  human  behavior.  She  knows  who  is  “selling” 
and who can be trusted. In short, she is nobody’s fool. 
So, what would interest Bertie this year? 
Operating Results, Fact and Fiction 
Let’s begin with the numbers. The official annual report begins on K-1 and extends for 124 
pages. It is filled with a vast amount of information – some important, some trivial. 
Among  its  disclosures  many  owners,  along  with  financial  reporters,  will  focus  on  page 
K-72.  There,  they  will  find  the  proverbial  “bottom  line”  labeled  “Net  earnings  (loss).”  The 
numbers read $90 billion for 2021, ($23 billion) for 2022 and $96 billion for 2023. 
What in the world is going on? 
You  seek  guidance  and  are  told  that  the  procedures  for  calculating  these  “earnings”  are 
promulgated  by  a  sober  and  credentialed  Financial  Accounting  Standards  Board  (“FASB”), 
mandated  by  a  dedicated  and  hard-working  Securities  and  Exchange  Commission  (“SEC”)  and 
audited by the world-class professionals at Deloitte & Touche (“D&T”). On page K-67, D&T pulls 
no punches: “In our opinion, the financial statements . . . . . present fairly, in all material respects 
(italics mine), the financial position of the Company . . . . . and the results of its operations . . . . . 
for each of the three years in the period ended December 31, 2023 . . . . .” 
So  sanctified,  this  worse-than-useless  “net  income”  figure  quickly  gets  transmitted 
throughout the world via the internet and media. All parties believe they have done their job – and, 
legally, they have. 
We, however, are left uncomfortable. At Berkshire, our view is that “earnings” should be a 
sensible  concept  that  Bertie  will  find  somewhat  useful  –  but  only  as  a  starting  point  –  in 
evaluating  a  business.  Accordingly,  Berkshire  also  reports  to  Bertie  and  you  what  we  call 
“operating earnings.” Here is the story they tell: $27.6 billion for 2021; $30.9 billion for 2022 and 
$37.4 billion for 2023. 
4 
The primary difference between the mandated figures and the ones Berkshire prefers is that 
we exclude unrealized capital gains or losses that at times can exceed $5 billion a day. Ironically, 
our  preference  was  pretty  much  the  rule  until  2018,  when  the  “improvement”  was  mandated. 
Galileo’s experience, several centuries ago, should have taught us not to mess with mandates from 
on high. But, at Berkshire, we can be stubborn. 
* * * * * * * * * * * * 
Make  no  mistake  about  the  significance  of  capital  gains:  I  expect  them  to  be  a  very 
important  component  of  Berkshire’s  value  accretion  during  the  decades  ahead.  Why  else  would 
we commit huge dollar amounts of your money (and Bertie’s) to marketable equities just as I have 
been doing with my own funds throughout my investing lifetime? 
I can’t remember a period since March 11, 1942 – the date of my first stock purchase – that 
I  have  not  had  a  majority  of  my  net  worth  in  equities,  U.S.-based  equities.  And  so  far,  so  good. 
The Dow Jones Industrial Average fell below 100 on that fateful day in 1942 when I “pulled the 
trigger.” I was down about $5 by the time school was out. Soon, things turned around and now that 
index  hovers  around  38,000.  America  has  been  a  terrific  country  for  investors.  All  they  have 
needed to do is sit quietly, listening to no one. 
It is more than silly, however, to make judgments about Berkshire’s investment value based 
on  “earnings”  that  incorporate  the  capricious  day-by-day and, yes, even year-by-year  movements 
of  the  stock  market.  As  Ben  Graham  taught  me,  “In  the  short  run  the  market  acts  as  a  voting 
machine; in the long run it becomes a weighing machine.” 
What We Do 
Our goal at Berkshire is simple: We want to own either all or a portion of businesses that 
enjoy good economics that are fundamental and enduring. Within capitalism, some businesses will 
flourish for a very long time while others will prove to be sinkholes. It’s harder than you would 
think to predict which will be the winners and losers. And those who tell you they know the answer 
are usually either self-delusional or snake-oil salesmen. 
At Berkshire, we particularly favor the rare enterprise that can deploy additional capital at 
high  returns  in  the  future.  Owning  only  one  of  these  companies  –  and  simply  sitting  tight  –  can 
deliver wealth almost beyond measure. Even heirs to such a holding can – ugh! – sometimes live 
a lifetime of leisure. 
We also hope these favored businesses are run by able and trustworthy managers, though 
that  is  a  more  difficult  judgment  to  make,  however,  and  Berkshire  has  had  its  share 
of disappointments.

In  1863,  Hugh  McCulloch,  the  first  Comptroller  of  the  United  States,  sent  a  letter  to  all 
national  banks.  His  instructions  included  this  warning:  “Never  deal  with  a  rascal  under  the 
expectation that you can prevent him from cheating you.” Many bankers who thought they could 
“manage” the rascal problem have learned the wisdom of Mr. McCulloch’s advice – and I have as 
well. People are not that easy to read. Sincerity and empathy can easily be faked. That is as true 
now as it was in 1863. 
This  combination  of  the  two  necessities  I’ve  described  for  acquiring  businesses  has  for 
long been our goal in purchases and, for a while, we had an abundance of candidates to evaluate. 
If I missed one – and I missed plenty – another always came along. 
Those days are long behind us; size did us in, though increased competition for purchases 
was also a factor. 
Berkshire  now  has  –  by  far  –  the  largest  GAAP  net  worth  recorded  by  any  American 
business.  Record  operating  income  and  a  strong  stock  market  led  to  a  yearend  figure  of  $561 
billion. The total GAAP net worth for the other 499 S&P companies – a who’s who of American 
business – was $8.9 trillion in 2022. (The 2023 number for the S&P has not yet been tallied but is 
unlikely to materially exceed $9.5 trillion.) 
By  this  measure,  Berkshire  now  occupies  nearly  6%  of  the  universe  in  which  it  operates. 
Doubling our huge base is simply not possible within, say, a five-year period, particularly because 
we are highly averse to issuing shares (an act that immediately juices net worth). 
There  remain  only  a  handful  of  companies  in  this  country  capable  of  truly  moving  the 
needle at Berkshire, and they have been endlessly picked over by us and by others. Some we can 
value; some we can’t. And, if we can, they have to be attractively priced. Outside the U.S., there 
are essentially no candidates that are meaningful options for capital deployment at Berkshire. All 
in all, we have no possibility of eye-popping performance. 
Nevertheless,  managing  Berkshire  is  mostly  fun  and  always  interesting.  On  the  positive 
side,  after  59  years  of  assemblage,  the  company  now  owns  either  a  portion  or  100%  of  various 
businesses  that,  on  a  weighted  basis,  have  somewhat  better  prospects  than  exist  at  most  large 
American  companies.  By  both  luck  and  pluck,  a  few  huge  winners  have  emerged  from  a  great 
many dozens of decisions. And we now have a small cadre of long-time managers who never muse 
about going elsewhere and who regard 65 as just another birthday. 
* * * * * * * * * * * * 
Berkshire benefits from an unusual constancy and clarity of purpose. While we emphasize 
treating  our  employees,  communities  and  suppliers  well  –  who  wouldn’t  wish  to  do  so?  –  our 
allegiance will always be to our country and our shareholders. We never forget that, though your 
money is comingled with ours, it does not belong to us. 
6 
With  that  focus,  and  with  our  present  mix  of  businesses,  Berkshire  should do  a bit better 
than  the  average  American  corporation  and,  more  important,  should  also  operate  with  materially 
less  risk  of  permanent  loss  of  capital.  Anything  beyond  “slightly  better,”  though,  is  wishful 
thinking.  This  modest  aspiration  wasn’t  the  case  when  Bertie  went  all-in  on  Berkshire  –  but  it 
is now. 
Our Not-So-Secret Weapon 
Occasionally, markets and/or the economy will cause stocks and bonds of some large and 
fundamentally  good  businesses  to  be  strikingly  mispriced.  Indeed,  markets  can  –  and 
will – unpredictably seize up or even vanish as they did for four months in 1914 and for a few days 
in 2001. If you believe that American investors are now more stable than in the past, think back to 
September  2008.  Speed  of  communication  and  the  wonders  of  technology  facilitate  instant 
worldwide paralysis, and we have come a long way since smoke signals. Such instant panics won’t 
happen often – but they will happen. 
Berkshire’s  ability  to  immediately  respond  to  market  seizures  with  both  huge  sums  and 
certainty  of  performance  may  offer  us  an  occasional  large-scale  opportunity.  Though  the  stock 
market  is  massively  larger  than  it  was  in  our  early  years,  today’s  active  participants  are  neither 
more emotionally stable nor better taught than when I was in school. For whatever reasons, markets 
now exhibit far more casino-like behavior than they did when I was young. The casino now resides 
in many homes and daily tempts the occupants. 
One  fact  of  financial  life  should  never  be  forgotten.  Wall  Street  –  to  use  the  term  in  its 
figurative  sense  –  would  like  its  customers  to  make  money,  but  what  truly  causes  its  denizens’ 
juices  to  flow  is  feverish  activity.  At  such  times,  whatever  foolishness  can  be  marketed  will  be 
vigorously marketed – not by everyone but always by someone. 
Occasionally, the scene turns ugly. The politicians then become enraged; the most flagrant 
perpetrators  of  misdeeds  slip  away,  rich  and  unpunished;  and  your  friend  next  door  becomes 
bewildered, poorer and sometimes vengeful. Money, he learns, has trumped morality. 
One  investment  rule  at  Berkshire  has  not  and  will  not  change:  Never  risk  permanent  loss 
of capital. Thanks to the American tailwind and the power of compound interest, the arena in which 
we operate  has been – and will be – rewarding if you make a couple of good decisions during a 
lifetime and avoid serious mistakes. 
* * * * * * * * * * * * 
I  believe  Berkshire  can  handle  financial  disasters  of  a  magnitude  beyond  any  heretofore 
experienced. This ability is one we will not relinquish. When economic upsets occur, as they will, 
Berkshire’s goal will be to function as an asset to the country – just as it was in a very minor way 
in 2008-9 – and to help extinguish the financial fire rather than to be among the many companies 
that, inadvertently or otherwise, ignited the conflagration. 
7 
Our  goal  is  realistic.  Berkshire’s  strength  comes  from  its  Niagara  of  diverse  earnings 
delivered  after  interest  costs,  taxes  and  substantial  charges  for  depreciation  and  amortization 
(“EBITDA”  is a banned measurement  at Berkshire). We also operate with minimal requirements 
for cash, even if the country encounters a prolonged period of global economic weakness, fear and 
near-paralysis. 
Berkshire  does  not  currently  pay  dividends,  and  its  share  repurchases  are  100% 
discretionary. Annual debt maturities are never material. 
Your  company  also  holds  a  cash  and  U.S.  Treasury  bill  position  far  in  excess  of  what 
conventional  wisdom  deems  necessary.  During  the  2008  panic,  Berkshire  generated  cash  from 
operations and did not rely in any manner on commercial  paper, bank lines or debt markets. We 
did not predict the time of an economic paralysis but we were always prepared for one. 
Extreme fiscal conservatism is a corporate pledge we make to those who have joined us in 
ownership of Berkshire. In most years – indeed in most decades – our caution will likely prove to 
be  unneeded  behavior  –  akin  to  an  insurance  policy  on  a  fortress-like  building  thought  to  be 
fireproof.  But  Berkshire  does  not  want  to  inflict  permanent  financial  damage  –  quotational 
shrinkage  for  extended  periods  can’t  be  avoided  –  on  Bertie  or  any  of  the  individuals  who  have 
trusted us with their savings. 
Berkshire is built to last. 
Non-controlled Businesses That Leave Us Comfortable 
Last  year 
I  mentioned 
long-duration  partial-ownership 
positions  –  Coca-Cola  and  American  Express.  These  are  not  huge  commitments  like  our  Apple 
position.  Each  only accounts  for 4-5% of Berkshire’s GAAP net worth. But they are meaningful 
assets and also illustrate our thought processes. 
two  of  Berkshire’s 
American  Express  began  operations  in  1850,  and  Coca-Cola  was  launched  in  an  Atlanta 
drug  store  in  1886.  (Berkshire  is  not  big  on  newcomers.)  Both  companies  tried  expanding  into 
unrelated  areas  over  the  years  and  both  found  little  success  in  these  attempts.  In  the  past  –  but 
definitely not now – both were even mismanaged. 
But each was hugely successful in its base business, reshaped here and there as conditions 
called for. And, crucially, their products “traveled.” Both Coke and AMEX became recognizable 
names  worldwide  as  did  their  core  products,  and  the  consumption  of  liquids  and  the  need  for 
unquestioned financial trust are timeless essentials of our world. 
8 
During 2023, we did not buy or sell a share of either AMEX or Coke – extending our own 
Rip  Van  Winkle  slumber  that  has  now  lasted  well  over  two  decades.  Both  companies  again 
rewarded  our  inaction  last  year  by  increasing  their  earnings  and  dividends.  Indeed,  our  share  of 
AMEX earnings in 2023 considerably exceeded the $1.3 billion cost of our long-ago purchase. 
Both AMEX and Coke will almost certainly increase their dividends in 2024 – about 16% 
in  the  case  of  AMEX – and  we  will  most  certainly  leave  our  holdings  untouched  throughout  the 
year.  Could  I  create  a  better  worldwide  business  than  these  two  enjoy?  As  Bertie  will  tell 
you: “No way.” 
Though  Berkshire  did  not  purchase  shares  of  either  company  in  2023,  your  indirect 
ownership of both Coke and AMEX increased a bit last year because of share repurchases we made 
at  Berkshire.  Such  repurchases  work  to  increase  your  participation  in  every  asset  that  Berkshire 
owns.  To  this  obvious  but  often  overlooked  truth,  I  add  my  usual  caveat:  All  stock  repurchases 
should be price-dependent. What is sensible at a discount to business-value becomes stupid if done 
at a premium. 
The lesson from Coke and AMEX? When you find a truly wonderful business, stick with 
it.  Patience  pays,  and  one  wonderful  business  can  offset  the  many  mediocre  decisions  that 
are inevitable. 
* * * * * * * * * * * * 
This  year,  I  would  like  to  describe  two  other  investments  that  we  expect  to  maintain 
indefinitely.  Like  Coke  and  AMEX,  these  commitments  are  not  huge  relative  to  our  resources. 
They are worthwhile, however, and we were able to increase both positions during 2023. 
At  yearend,  Berkshire  owned  27.8%  of  Occidental  Petroleum’s  common  shares  and  also 
owned  warrants  that,  for  more  than  five  years,  give  us  the  option  to  materially  increase  our 
ownership  at  a  fixed  price.  Though  we  very  much  like  our  ownership,  as  well  as  the  option, 
Berkshire  has  no  interest  in  purchasing  or  managing  Occidental.  We  particularly  like  its  vast  oil 
and gas holdings in the United States, as well as its leadership in carbon-capture initiatives, though 
the  economic  feasibility  of  this  technique  has  yet  to  be  proven.  Both  of  these  activities  are  very 
much in our country’s interest. 
Not so long ago, the U.S. was woefully dependent on foreign oil, and carbon capture had 
no  meaningful  constituency.  Indeed,  in  1975,  U.S.  production  was  eight  million  barrels  of 
oil-equivalent  per  day  (“BOEPD”),  a  level  far  short  of  the  country’s  needs.  From  the  favorable 
energy position that facilitated the U.S. mobilization in World War II, the country had retreated to 
become  heavily  dependent  on  foreign  –  potentially  unstable  –  suppliers.  Further  declines  in  oil 
production were predicted along with future increases in usage.
