Warren Buffett is stepping down as chairman of Berkshire Hathaway, marking the next stage in the leadership transition at the trillion-dollar conglomerate he has led for more than 60 years.

ウォーレン・バフェットは、60年以上にわたって率いてきた時価総額1兆ドルの複合企業のトップ交代の次の段階として、バークシャー・ハサウェイの会長職を退任する。

On Friday, the company announced that Buffett, aged 96, will become chairman emeritus and take on his new role immediately.

同社は金曜日96歳のバフェットが名誉会長に就任し直ちに新たな役割に就く予定であると発表した

His eldest son, Howard, is set to become Berkshire Hathaway's new chairman, as part of a long-planned succession strategy.

長男のハワードがバークシャー・ハサウェイの新会長に就任する運びでありこれは長く計画されてきた後継者計画の一環である

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

ハワード・バフェットは1993年からバークシャー・ハサウェイの取締役を務めている

Warren Buffett, known to many followers of the financial markets as the "Sage of Omaha," will continue to serve as a director.

金融市場の多くのフォロワーから「オマハの賢人」として知られるウォーレン・バフェットは引き続き取締役を務める

He had served as chairman of Berkshire Hathaway since 1970, having taken control in 1965 of a New England textile company that had fallen into financial difficulties.

彼は1970年からバークシャー・ハサウェイの会長を務めてきたが、1965年に経営難に陥っていたニューイングランドの繊維会社の支配権を握った

Earlier this year, Greg Abel succeeded Buffett as CEO of this conglomerate, which has a market capitalization of one trillion dollars.

グレッグ・アベルは今年初め時価総額1兆ドルのこの複合企業のCEOとしてバフェットの後を引き継いだ

However, Buffett continued to go to the office every day after that, offering advice to Abel while exploring new investments and deals.

しかしバフェットはその後も毎日オフィスに出勤し新たな投資や取引を模索しながらアベルに助言を提供し続けていた

It is not clear whether Buffett will now change his daily routine.

バフェットが自身の日課を変えるかどうかは明らかではない

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

私は1965年からバークシャーに奉仕してきたとバフェットは株主への書簡で述べた

"Even now, more than 60 years later, I hold the best job in the world.

60年以上経った今でも私は世界で最高の仕事を持っている

This is not something many people my age can say, and I have never felt so positive about what lies ahead."

これは私の年齢の多くの人が言えることではなく、今後のことについてこれほど前向きに感じたことはない。」

Investor Adam Mead, author of "The Complete Financial History of Berkshire Hathaway," said that by taking this step now, Buffett appears to be aiming to soften the impact on Berkshire when he eventually passes away.

『バークシャー・ハサウェイの完全な財務史』の著者である投資家アダム・ミード氏はバフェットが今この段階を踏むことにより最終的に逝去した際のバークシャーへの影響を緩和しようと企図しているように見受けられると述べた

Although Berkshire's announcement did not reveal any health concerns about Buffett, Mead remarked, "Since he is now 96, even a cold can become a health scare."

バークシャーの公表はバフェットの健康上の懸念を明らかにするものではなかったがミード氏は「彼は現在96歳であるため風邪であっても健康上の scare となり得る」と述べた

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

バフェットは、アベルと息子のハワードがバークシャー・ハサウェイを率いることに対し、揺るぎない自信を抱いていると述べた。

"Greg runs the company, while Howard safeguards its culture and values.

グレッグが会社を経営しハワードがその文化と価値観を守っている

Both are worth more than any single item on our balance sheet," he stated.

どちらも我々の貸借対照表上のあらゆる項目よりも価値があると彼は述べた

"I would like you to think of Howard as something akin to an insurance policy that shareholders hold and hope never to claim on."

ハワードは株主が保有し決して請求しないことを願う保険のようなものだと考えていただきたい。」

When Abel was promoted to vice chairman in 2018, he took charge of all of Berkshire's non-insurance operations, and as a result he is thoroughly familiar with a diverse array of businesses, including the BNSF railroad, utilities, manufacturing, and well-known brands such as Dairy Queen and See's Candies.

アベルは2018年に副会長に昇進した際バークシャーの保険以外の全事業を統括する立場となったためBNSF鉄道公益事業製造業そしてデイリークイーンやシーズキャンディといった著名ブランドを含む多様な企業群に精通している

However, Cathy Seifert, an analyst at CFRA Research, said that investors still harbor doubts about Abel's ability to manage Berkshire's enormous cash pile of $365 billion.

しかしCFRAリサーチのアナリストキャシー・サイファート氏は投資家がアベルによるバークシャーの3650億ドルという巨額の現金の運用能力について依然として疑問を抱いていると述べた

"Berkshire's stock carried a premium for its financial strength and for the presence of this renowned investor who has been allocating its capital.

バークシャーの株式には財務的な強さと資本を配分してきたこの著名な投資家の存在に対するプレミアムが付いていた

It would be naive to assume that this is business as usual.

これを通常通りの事業運営だと仮定するのは naive だ

It is not," Seifert said.

そうではないとサイファート氏は述べた

"What this does is amplify the execution risk in the strategy and the importance of the transition."

これが行うことは戦略における実行リスクと移行の重要性を増幅させることだ。」

Michael Withers, a professor of management at the University of Notre Dame's Mendoza College of Business, said that Buffett has deliberately worked on a succession plan for Berkshire Hathaway and has carried out the transition in stages.

ノートルダム大学メンドーサ・ビジネス・カレッジの経営学教授マイケル・ウィザーズ氏はバフェットがバークシャー・ハサウェイの後継者計画に意図的に取り組み、その移行を段階的に進めてきた述べた

"It seems Buffett understood that choosing his successor was not simply a matter of finding another outstanding leader," he said.

バフェットは自身の後継を選ぶことは単に別の卓越したリーダーを見つけるだけでは済まないと理解していたようだと彼は述べた

"It was about building a structure capable of preserving what makes Berkshire special long after he is gone.

それは彼が去った後も長くバークシャーを特別たらしめるものを維持できる仕組みを築くことだった

The challenge ahead is whether Abel and Howard can honor that legacy while allowing Berkshire the room to adapt to markets vastly different from the ones Buffett mastered."

今後の試練はアベルとハワードがバフェットが習得したものとは大きく異なる市場にバークシャーが適応する余地を与えつつその遺産を尊重できるかどうかだ。」

Buffett's fortune was accumulated through shares in Berkshire Hathaway.

バフェットの財産はバークシャー・ハサウェイの株式を通じて蓄積された

By acquiring insurance companies and reinvesting the funds from insurance premiums into stocks and other businesses, Buffett built the company into an investment conglomerate and a symbol of Wall Street.

バフェットは保険会社を買収し保険料からの資金を株式や他の企業に再投資することにより、同社を投資複合企業およびウォール街の象徴へと育て上げた

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

2024年バークシャー・ハサウェイは時価総額1兆ドルを超えた最初の非テクノロジー企業となった

Buffett, a longtime philanthropist, has donated shares worth roughly $66 billion since 2006, with the bulk of that going to the foundation of his friend Bill Gates.

長年の慈善家であるバフェットは2006年以来約660億ドル相当の株式を寄付しておりその大部分は友人のビル・ゲイツの財団に寄せられている

This summer, however, he announced that his three children would take over all future philanthropic decisions and distribute the remainder of his fortune by the end of 2034.

しかしこの夏彼は3人の子供たちが今後すべての慈善活動の決定を引き継ぎ2034年末までに残りの財産を分配する発表した

Buffett's views on finance generate a gravitational pull of their own.

バフェットの金融に対する見解はそれ自体が引力を生み出している

When Berkshire Hathaway discloses in public filings which stocks it has bought or sold, it can shake the markets.

バークシャー・ハサウェイが公開開示で同社が取得または売却した株式を明らかにすると市場を揺るがすことがある

During his tenure as CEO of Berkshire Hathaway, the company nearly doubled the returns of the S&P 500, recording an average annual growth rate of 19.9%, while the index's growth amounted to only 10.4%.

バークシャー・ハサウェイのCEO在任中、同社はS&P 500のリターンをほぼ2倍にし、年平均成長率19.9%を記録した一方で、同指数の伸びは10.4%にとどまった。

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

アベルは準備された声明で、「ウォーレンのバークシャーとその所有者への影響はアメリカのビジネス史において並ぶものがない」と述べた

"The culture Warren built and the values he championed will remain at the heart of Berkshire, and Howard will be their guardian."

ウォーレンが築いた文化と彼が擁護した価値観はバークシャーの中心に残り続けハワードがその守護者となるだろう。」

Berkshire Hathaway's share price was set to edge lower in Friday morning trading.

バークシャー・ハサウェイの株価は、金曜日の朝の取引において、わずかながら下落する運びとなった。
