Salem Communications Inc. announced a 5 percent increase in its quarterly dividend on Friday. The Christian broadcaster and publisher, based in Camarillo, said the dividend will increase from 5 cents a share to 5.25 cents. The first distribution of the new dividend will occur Oct. 4 for shareholders of record on Sept. 26. “This increase in our cash distribution is in response to our growing free cash-flow stemming from both our refinancing that was completed in March and from our operations, particularly the growth in our Internet division,” said Chief Executive Edward Atsinger III, in a statement. Salem owns nearly 100 radio stations, in addition to a radio network and a group of Christian websites. Shares lost 1 cent, or a fraction of 1 percent, to close at $8.16 on the Nasdaq.
