Borders Group Inc., which has stopped writing checks to key suppliers, is expected to ask publishers on Wednesday to push back the due dates on bills as it works out a refinancing plan, according to people familiar with the situation.

Such a move would allow Borders to conserve cash. It's unclear whether publishers will agree to the request.

At one publishing company, Borders halted payment on a check that covered books shipped in October, according to an executive.

The executive also expressed concern about expected payments due at the end of January for books shipped in November and February payment for books shipped in December.

One supplier said that he is eager to hear what Borders has to say.

Borders declined to comment.

Meanwhile, changes are being made in the management ranks. Thomas Carney, general counsel, voluntarily resigned Jan. 2. The chief information officer departed Jan. 3, according to a regulatory filing.

On top of those executive changes, several other senior managers have departed Borders as part of a Jan. 3 reorganization, including Tony Grant, vice president of real estate; Bill Dandy, senior vice president, marketing; and Larry Norton, senior vice president for business development.

"We think the playing field should be even. We expect publishers to offer the same terms to all other booksellers including Barnes & Noble and independent booksellers," Barnes & Noble said in a statement.

Barnes & Noble also added that it expects book publishers "will require Borders to pay their bills on the same basis upon which all other booksellers pay theirs. Any changes in publishers' terms should be made available to all."
