The Software Products Group was acquired by SCO in December 1986; it became a wholly owned subsidiary, the Santa Cruz Operation Limited, and the basis for SCO's UK operation, with its office subsequently being relocated first to Soho and then to Watford outside London. Initially supplemented by some engineers who transferred from SCO's headquarters operation in Santa Cruz, California, the ex-Logica group now in Watford became one of the major development sites for SCO and over the next few years did the operating system kernel development work behind the subsequent SCO OpenDesktop and SCO OpenServer product releases, as well as later working in networking, security, escalations, and other areas, in addition to being the sales, marketing, and customer engineering hub for SCO's (and later Caldera International's) EMEA region (although most development work in Watford was shut down in 2000).
