The $9.09 trillion New York-based asset manager began providing executive protection services to Mr. Fink in 2022, including security guards and upgraded home security systems at his private residences. The price tag was $376,360 in 2022, according to the firm's May 24 proxy statement.
Similar services for Mr. Kapito began in early 2023, the proxy said.
The new, boosted residential protection for both executives comes on top of existing travel safety benefits, including ground transportation services and a $295,000 annual allowance for private jets.
According to BlackRock's proxy statement, the company's board of directors made the decision to tighten security for Messrs. Fink and Kapito last year, to "address potential threats to their safety that have originated in connection with their roles."
A spokesman for BlackRock declined to comment on what security concerns led to the decision to upgrade Messrs. Fink and Kapito's home security, saying only that "BlackRock has a robust security program in place aimed at protecting our employees and offices."
The criticism of BlackRock comes from across the political spectrum. Last fall, a small group of climate activists protested BlackRock's investment in fossil fuels at the company's New York headquarters, blocking escalators and reportedly strewing coal across the floors. Earlier this year, climate activists heckled Mr. Kapito at a financial conference in New York.
The company has also drawn the ire of Republicans, who claim BlackRock's ESG investing is an overreach that unfairly discriminates against the energy industries in red states.
And in France earlier this year, anti-pension reform protesters stormed BlackRock's Paris headquarters with smoke bombs and flares.
