According to this file Westinghouse is essentially trading or exchanging two stations for krdc and klsx Los Angeles.
It states this.
The transactions proposed in the above-captioned applications represent a like-kind exchange of
assets between Westinghouse and its subsidiary Infinity WOAZ-FM, Inc., and GLAR. Westinghouse
proposes to exchange WOAZ(FM), WBOS(FM), and WMMR(FM) for KRLA(AM) and KLSX(FM), which
are owned by GLAR. This exchange will enable Westinghouse to complete the divestiture of stations in
Boston and Philadelphia related to its earlier acquisition of Infinity Broadcasting Corporation that is required
by the terms of a consent decree between Westinghouse and the Department of Justice settling a civil
antitrust case related to the merger of Infinity and Westinghouse.
