Under fire for its role in handling the data breach, Target's board defended itself to shareholders on Monday in a bid to hold on to its seats in voting at next week's annual meeting.
In a letter sent to its largest investors, Roxanne Austin, the board's interim chairwoman, outlined the actions the Minneapolis retailer took before and after the data breach to protect customer data and asked them to re-elect the entire board.
"We want to assure you that the board takes its oversight responsibilities seriously and we recognize the importance of Target addressing these information security issues in the most effective manner possible," she said.
Target would not comment beyond the letter.
The letter came several days after a report by Institutional Shareholder Services (ISS), a prominent proxy adviser, urged investors to oust seven of the retailer's 10 board members, including Austin. It argued that the board failed to protect the company against last year's breach in which tens of millions of customers' personal and financial information was compromised.
Austin countered that data breaches have affected a "wide range of victims" including the U.S. government, technology companies and retailers.
"Cybercrime is a real and persistent threat as sophisticated criminals are constantly seeking to breach information networks and steal data," she wrote in the letter, which also was filed with the Securities and Exchange Commission.
Under the board's leadership, she said, Target took significant actions before the breach to address cybertheft risks. For example, she said Target invested hundreds of millions of dollars in network security personnel and technology, doubled the number of information security employees over five years, and staffed a security operations center around the clock to review suspicious network activity.
