Syniverse Holdings Inc., which provides services to telecommunications companies, is eliminating the "poison pill" element of its share structure.

The company added the amendment in 2008 because of its depressed share price — which was trading below $9 at the time. It's a step generally adopted by companies to avert hostile takeovers, although Syniverse said it had no information about any pending buyout offer at the time.

The company said that portion of the rights plan expires as of Friday, rather than in 2011 as planned.

Shares of Syniverse fell 23 cents to close at $22.33.
