Honeywell adopted an anti-takeover plan.

The Minneapolis-based computer company said the measure was designed to protect shareholders’ interests in the event of a hostile bid. Shareholders will be issued stock-purchase rights as a dividend. Under certain conditions, if an unfriendly suitor should buy 20% or more of Honeywell’s stock, those rights can be used to purchase a new preferred stock. The plan would make a takeover more difficult and more expensive.
