NEW YORK, Sept 5 (Reuters) - BNY has agreed to

buy Archer, a technology and operations provider that will help

the U.S. bank expand its services to asset and wealth managers,

the companies said on Thursday.

BNY and Archer did not disclose the deal value. The

transaction is expected close in the fourth quarter if approved

by regulators.

The combination will enable BNY to offer more managed

account services using Archer's cloud-based platform.

"Managed accounts are one of the fastest-growing investment

vehicles in the asset management industry, enabling investment

advisors and asset managers to offer customized portfolios to

retail investors," said Emily Portney, global head of asset

servicing at BNY.
