THE ESSENCE: It was a disappoint-ing year for Kirshenbaum Bond & Partners. Liberty Mutual left with its $50 million creative. Also gone are Timex and Equal. One of two finalists for BMW's ad account, it lost to GSD&M for lead status, but did win CRM responsibilities. On the bright side, it turned out some smart programs for clients, and won creative duties for CIBA Vision, restaurant chain Carrabba's and media duties for Limited Brands. However, a major blow came for the agency in Decem-ber, when one of its top executives, media chief Paul Woolmington, left for a London import's New York outpost.
