Acquirers include hedge funds , private equity firms, management-led investor groups, and other companies. As the closing date nears and issues are resolved, the spread typically narrows. Tender offers provide several advantages to investors. For example, investors are not obligated to buy shares until a set number are tendered, which eliminates large upfront cash outlays and prevents investors from liquidating stock positions if offers fail.

Acquirers can also include escape clauses, releasing liability for buying shares. For example, if the government rejects a proposed acquisition citing anti-trust violations, the acquirer can refuse to buy tendered shares. In many instances, investors gain control of target companies in less than one month if shareholders accept their offers; they also generally earn more than normal investments in the stock market.

Although tender offers provide many benefits, there are some noted disadvantages. A tender offer is an expensive way to complete a hostile takeover as investors pay SEC filing fees, attorney costs, and other fees for specialized services. It can be a time-consuming process as depository banks verify tendered shares and issue payments on behalf of the investor. Also, if other investors become involved in a hostile takeover, the offer price increases, and because there are no guarantees, the investor may lose money on the deal.

What is 'Tender Offer' A tender offer is an offer to purchase some or all of shareholders' shares in a corporation. Learn about the potential benefits that the debt tender offer by Cliffs Natural Resources had for the company's balance sheet and income statement.

A stock buyback, or repurchase, occurs when a company buys its own shares off the market and therefore reduces the amount of stock outstanding. It was first announced at the Rump session of Eurocrypt The new attack allows to recover the secret key of any sector of MIFARE Classic card via wireless interaction, within about queries to the card.

It can then be combined with the nested authentication attack in the Nijmegen Oakland paper to recover subsequent keys almost instantly. Both attacks combined and with the right hardware equipment such as Proxmark3, one should be able to clone any MIFARE Classic card in not more than 10 seconds.

This is much faster than previously thought. In , a new card-only attack was discovered that is also able to recover the secret keys from such hardened variants.

Furthermore, the paper's authors included hardware schematics for their original cloning device, and have since made corresponding software, firmware and improved hardware schematics publicly available on GitHub.

Power Analysis and Templates in the Real World", [52] they stated that system integrators should be aware of the new security risks that arise from the presented attacks and can no longer rely on the mathematical security of the used 3DES cipher. Hence, in order to avoid, e. NXP also stated "Also, the impact of a successful attack depends on the end-to-end system security design of each individual infrastructure and whether diversified keys — recommended by NXP — are being used.

If this is the case, a stolen or lost card can be disabled simply by the operator detecting the fraud and blacklisting the card, however this operation assumes that the operator has those mechanisms implemented.

This will make it even harder to replicate the attack with a commercial purpose. This can be overcome by having a copy of the register online so that values can be analysed and suspect cards hot-listed.

For systems based on contactless smartcards e. Typically, to minimize costs, systems integrators will choose a relatively cheap card such as a MIFARE Classic and concentrate security efforts in the back office.

Additional encryption on the card, transaction counters, and other methods known in cryptography are then employed to make cloned cards useless, or at least to enable the back office to detect a fraudulent card, and put it on a blacklist. Systems that work with online readers only i. Another aspect of fraud prevention and compatibility guarantee is to obtain certification called to life in ensuring the compatibility of several certified MIFARE product-based cards with multiple readers.

With this certification , the main focus was placed on the contactless communication of the wireless interface, as well as to ensure proper implementation of all the commands of MIFARE product-based cards.

The certification process was developed and carried out by the Austrian laboratory called Arsenal Research. From Wikipedia, the free encyclopedia.
