A disability insurer is giving investors more time to sell its debt securities.

Unum, Chattanooga, Tenn., originally announced a plan to make up to $400 million in cash tender offers for the securities Oct. 31.

Debt securities eligible for the program include notes, bonds and debentures with interest rates ranging from 4.5% to 9.125%.

Securities holders who offer debt securities before an “early tender date” are supposed to get an extra $30 per $1,000 of principal amount or liquidation amount.

Unum now pushed the early tender date back to 5 p.m. Nov. 19, from the original date of 5 p.m. Nov. 14.

Unum is not saying why it has postponed the early tender date.
