Lucerne Capital Management has leased 4,733 s/f for its headquarters at W&M Properties' 500 Mamaroneck Ave., according to Jeffrey Newman, executive VP of W&M Properties, the marketing and managing agent for the building. Stephen Banker, managing principal at Newmark Knight Frank, represented the new tenant.

HCL Jones was looking to shed a portion of its underutilized 12,000 s/f office, and the space fit Lucerne Capital's needs. In order to accommodate Lucerne, W&M allowed HCL Jones to "buy out" a portion of its remaining lease obligation.
