Boston Man Sentenced to Prison for Scheme to Defraud Brokerage Firms

For Immediate Release
U.S. Attorney's Office, District of Massachusetts

BOSTON – A Boston man was sentenced today in U.S. District Court in Boston in connection with a three-year, multi-million-dollar fraud scheme.


Nathanial Ponn, 28, was sentenced by U.S. District Court Judge Allison D. Burroughs to 15 months in prison and ordered to pay restitution of $20,738, after pleading guilty in December 2016 to three counts of wire fraud.


From 2012 to April 2015, Ponn opened more than 400 brokerage accounts at nine investment firms throughout the United States, using false names, Social Security numbers, assets and income. These firms allowed customers to transfer funds from one financial institution into the customer’s brokerage account through an Automated Clearing House (ACH) transfer, by providing the account number and financial institution where the account was held and the amount to be transferred. Between February 2014 to April 2015, Ponn provided ACH transfer information to brokerage firms for accounts he opened on more than 350 occasions, totaling more than $8.5 million in attempted transfers. In each instance, the bank account Ponn provided did not have the amount of funds requested or, in some circumstances, did not even exist. Although the ACH transfers were rejected, the fraudulent transfers created the false appearance that the brokerage accounts had cash available to purchase securities.


Through this scheme, Ponn was able to purchase securities totaling more than $2.7 million in accounts at eight investment firms. When the firms discovered that the ACH transfers were rejected, they liquidated the securities in Ponn’s accounts. As part of the scheme, Ponn also attempted, unsuccessfully, to get the brokerage firms to send him checks totaling about $250,000, based on the same false ACH information.


The U.S. Attorney’s Office received valuable assistance from the Securities and Exchange Commission, which filed a civil action against Ponn in March 2016 arising out of the scheme to defraud investment firms.


Acting United States Attorney William D. Weinreb and Harold H. Shaw, Special Agent in Charge of the Federal Bureau of Investigation, Boston Field Division, made the announcement today. Assistant U.S. Attorney Mark J. Balthazard of Weinreb’s Economic Crimes Unit prosecuted the case.
