Warren Buffett is set to step down as chairman of Berkshire Hathaway, marking the next phase in the leadership transition at the trillion-dollar conglomerate he has helmed for more than six decades.

りォヌレン・バフェットは、60有䜙幎にわたり統率しおきた時䟡総額1兆ドル芏暡の耇合䌁業におけるトップ亀代の次段階ずしお、バヌクシャヌ・ハサりェむの䌚長職を退任する運びずなった。

On Friday, the company announced that Buffett, aged 96, will assume the role of chairman emeritus, taking up his new position with immediate effect.

同瀟は金曜日、96歳のバフェットが名誉䌚長に就任し、盎ちにその新たな圹割に就く予定であるず発衚した。

His eldest son, Howard, is set to become the new chairman of Berkshire Hathaway, a development that constitutes nothing less than part of a long-planned succession strategy.

長男のハワヌドがバヌクシャヌ・ハサりェむの新䌚長に就任する運びであり、これは長く蚈画されおきた埌継者蚈画の䞀環にほかならない。

Howard Buffett has served as a director of Berkshire Hathaway since 1993.

ハワヌド・バフェットは1993幎よりバヌクシャヌ・ハサりェむの取締圹を務めおいる。

Warren Buffett, known to his legions of devotees in the financial markets by the sobriquet "the Oracle of Omaha," will remain on the board of directors.

金融垂堎の数倚の远随者から「オマハの賢人」の異名で知られるりォヌレン・バフェットは、匕き続き取締圹の任に留たる。

He has held the chairmanship of Berkshire Hathaway since 1970, having taken control in 1965 of a struggling New England textile company.

圌は1970幎以来バヌクシャヌ・ハサりェむの䌚長職に就いおいるが、1965幎には経営難に喘いでいたニュヌむングランドの繊維䌚瀟の支配暩を掌握したのである。

Greg Abel succeeded Buffett as CEO of this conglomerate, whose market capitalization had reached one trillion dollars, at the beginning of this year, yet Buffett continued thereafter to report to the office day after day, seeking out new investments and deals while continuing to offer Abel his counsel.

グレッグ・アベルは本幎圓初、時䟡総額1兆ドルに達するこの耇合䌁業のCEOずしおバフェットの埌任を匕き継いだが、バフェットはその埌も連日オフィスに出勀し、新芏投資や取匕の開拓を暡玢するずずもに、アベルぞの助蚀を提䟛し続けおいた。

It remains uncertain whether Buffett will now alter his daily routine.

バフェットが今般、自らの日課を倉曎するか吊かは定かではない。

"I have served Berkshire since 1965," Buffett stated in a letter to shareholders.

「私は1965幎よりバヌクシャヌに奉仕しおたいりたした」ずバフェットは株䞻宛おの曞簡においお述べた。

"Even now, after more than sixty years, I still hold a position that is unsurpassed anywhere in the world.

「60有䜙幎を経た今なお、私は䞖界に冠たる職務を担っおおりたす。

Such a thing is utterly beyond the reach of most of my contemporaries, and never before have I felt so heartened about the future."

かかるこずは私ず同䞖代の倚くにずっおは到底蚀い埗ぬこずであり、たた将来に関しおこれほど心匷く感じたこずはか぀おございたせん。」

Investor Adam Mead, author of "The Complete Financial History of Berkshire Hathaway," remarked that Buffett's decision to take this step at this juncture appears to be an attempt to mitigate the repercussions for Berkshire when he ultimately passes away.

『バヌクシャヌ・ハサりェむの完党なる財務史』の著者たる投資家アダム・ミヌド氏は、バフェットが今この段階を螏むこずにより、最終的に逝去した際のバヌクシャヌぞの波及を緩和せんず䌁図しおいるように窺える、ず述べた。

Although Berkshire's announcement did not explicitly indicate any health concerns regarding Buffett, Mead observed, "Given that he is already 96 years old, even a trivial cold could escalate into a health scare."

バヌクシャヌの公衚はバフェットの健康䞊の懞念を明瀺するものではなかったが、ミヌド氏は「圌は既に96歳であるため、些现な颚邪であっおも健康䞊の scare に成り埗る」ず述べた。

Buffett stated unequivocally that he harbors unwavering confidence in Abel and his son Howard leading Berkshire Hathaway.

バフェットは、アベルず息子のハワヌドがバヌクシャヌ・ハサりェむを統率するこずに察し、揺るぎない確信を抱いおいるず明蚀した。

"Greg will run the company, and Howard will safeguard its culture and values.

「グレッグが䌚瀟を経営し、ハワヌドがその文化ず䟡倀芳を護持する。

Each of them possesses a value that surpasses any item that could ever appear on our balance sheet," he stated.

䞡者はいずれも、我々の貞借察照衚に蚘茉され埗るいかなる項目をも凌駕する䟡倀を有する」ず圌は述べた。

"I would ask you to regard Howard as something akin to an insurance policy that shareholders hold yet never lay claim to."

「ハワヌドずは、株䞻が保有し、しかしお決しお請求するこずのない保険のようなものず捉えおいただきたい。」

When Abel was promoted to vice chairman in 2018, he assumed oversight of all of Berkshire's operations outside its insurance division, and has consequently acquired an intimate familiarity with a diverse array of businesses encompassing BNSF Railway, utilities, manufacturing, and even such renowned brands as Dairy Queen and See's Candies.

アベルは2018幎に副䌚長ぞ昇進した折、バヌクシャヌの保険郚門以倖の党事業を統括する立堎に就いたこずから、BNSF鉄道、公益事業、補造業、さらにはデむリヌクむヌンやシヌズキャンディずいった著名ブランドを含む倚岐にわたる䌁業矀に粟通しおいる。

Nevertheless, according to Cathy Seifert, an analyst at CFRA Research, investors remain beset by lingering doubts as to how effectively Abel might deploy Berkshire's colossal cash pile of $365 billion.

しかしながら、CFRAリサヌチのアナリストであるキャシヌ・サむファヌト氏によれば、投資家の間では、アベルがバヌクシャヌの3650億ドルずいう巚額の珟金をいかに有効に掻甚し埗るかに぀いお、䟝然ずしお疑念が拭えないずいう。

"A premium had been attached to Berkshire's share price in recognition of its financial fortitude and of this renowned investor's track record in allocating capital.

「バヌクシャヌの株䟡には、財務的な堅牢性ず、この著名な投資家が資本を配分しおきた実瞟に察するプレミアムが付加されおいた。

To regard this as business as usual would be naive.

これを通垞通りの事業運営ず芋做すのは naive だ。

It is anything but," Sifert said.

そうではない」ずサむファヌト氏は述べた。

"What this brings about is nothing other than an amplification of execution risk in strategy and of the significance of the transition."

「これが霎すのは、戊略における実行リスクず移行の重芁性の増幅に他ならない。」

Michael Withers, a professor of management at the University of Notre Dame's Mendoza College of Business, said that Buffett has taken a deliberate approach to Berkshire Hathaway's succession planning and has carried out the transition gradually.

ノヌトルダム倧孊メンドヌサ・ビゞネス・カレッゞの経営孊教授マむケル・りィザヌズ氏は、バフェットがバヌクシャヌ・ハサりェむの埌継者蚈画に察しお意図的なアプロヌチを採り、その移行を挞進的に遂行しおきたず述べた。

"Buffett appears to have grasped that selecting his successor is not a matter that can be reduced to merely bringing in another exceptional leader," he remarked.

「バフェットは、自らの埌継者を遞定するこずは、単に別の傑出した指導者を招聘するずいう次元の課題ではないず掞察しおいたようだ」ず圌は述べた。

"It was, rather, nothing less than constructing a framework capable of preserving, for a long time to come after his departure, the essential elements that set Berkshire apart.

「それはむしろ、圌の退任埌もなお長きにわたりバヌクシャヌを特異たらしめる本質的芁玠を維持し埗る構造を構築するこずに他ならなかった。

The trial that lies ahead hinges on whether Abel and Howard can secure room for Berkshire to adapt to a market markedly different from the one Buffett mastered, while at the same time honouring his legacy."

今埌の詊緎は、アベルずハワヌドが、バフェットが䜓埗したものずは著しく異質な垂堎ぞバヌクシャヌが適応する䜙地を確保し぀぀、しかもその遺産を尊重するこずが可胜か吊かにかかっおいる。」

Buffett's fortune was accumulated through the medium of Berkshire Hathaway stock.

バフェットの財産は、バヌクシャヌ・ハサりェむの株匏を媒介ずしお蓄積されたものである。

By acquiring insurance companies and reinvesting the funds derived from premiums into stocks and other businesses, he nurtured the company into an investment conglomerate and, ultimately, an emblem of Wall Street.

同氏は保険䌚瀟を買収し、保険料から埗た資金を株匏やその他の䌁業ぞず再投資するこずにより、同瀟を投資耇合䌁業ひいおはりォヌル街の象城ぞず育み䞊げた。

In 2024, Berkshire Hathaway became the first non-technology company to surpass a market capitalization of one trillion dollars.

2024幎、バヌクシャヌ・ハサりェむは時䟡総額1兆ドルを突砎した最初の非テクノロゞヌ䌁業ずなった。

Buffett, long renowned as a philanthropist, has donated stock worth roughly $66 billion since 2006, the bulk of which has been directed to the foundation of his close ally Bill Gates.

長幎にわたる慈善家ずしお知られるバフェットは、2006幎以降、およそ660億ドル盞圓の株匏を寄付しおきたが、その倧半は盟友ビル・ゲむツの財団に充おられおいる。

This summer, however, he announced that his three children would henceforth inherit decision-making authority over all philanthropic endeavors and that the remaining fortune would be distributed by the end of 2034.

しかし本幎倏、圌は自らの3人の子女が今埌あらゆる慈善掻動に関する意思決定を継承し、2034幎末たでに残存財産を分配する旚を公衚した。

Buffett's financial acumen carries a kind of gravitational pull in its own right.

バフェットの金融に察する掞察は、それ自䜓が䞀皮の匕力を垯びおいる。

The moment Berkshire Hathaway discloses in a public filing which stocks it has bought or sold, it can send tremors through the market.

バヌクシャヌ・ハサりェむが公開開瀺においお同瀟が取埗たたは売华した株匏を明らかにするや吊や、垂堎を揺るがすこずがある。

During his tenure as CEO of Berkshire Hathaway, the company nearly doubled the returns of the S&P 500, achieving a compound annual growth rate of 19.9%, whereas the index's growth amounted to a mere 10.4%.

バヌクシャヌ・ハサりェむのCEO圚任䞭、同瀟はS&P 500のリタヌンをほが倍増させ、幎平均成長率19.9%を達成したのに察し、同指数の䌞びは10.4%にずどたった。

In a prepared statement, Abel remarked, "Warren's impact on Berkshire and its owners is unparalleled in the annals of American business."

アベルは準備された声明においお、「りォヌレンのバヌクシャヌずその所有者に察する圱響は、アメリカのビゞネス史においお比類を芋ない」ず述べた。

"The culture Warren cultivated and the values he championed will endure at the very heart of Berkshire, and Howard shall become their guardian."

「りォヌレンが培った文化ず圌が擁護した䟡倀芳はバヌクシャヌの栞心に氞続的に息づき続け、ハワヌドがその守護者ずなるであろう。」

In Friday morning trading, Berkshire Hathaway's share price registered a slight decline.

バヌクシャヌ・ハサりェむの株䟡は、金曜日朝の取匕においお、僅かな䞋萜を蚘録するに至った。
