The former CFO of American Realty Capital Properties was sentenced to 18 months in prison on Wednesday after he was found guilty of deceiving investors. Brian Block was sentenced by U.S. Prosecutors had sought a sentence of seven years, after calculating that non-binding federal sentencing guidelines would call for 105 years. In imposing the sentence, Oetken said he believed Block had deliberately falsified American Realty’s accounts, and had lied about it at trial, warranting a “significant sentence.”
