Below is the Pennsylvania statute language for Theft by Failure to Make Required Dispositions of Funds Received.

§ 3927.  Theft by failure to make required disposition of funds
                received.
        (a)  Offense defined.--A person who obtains property upon
     agreement, or subject to a known legal obligation, to make
     specified payments or other disposition, whether from such
     property or its proceeds or from his own property to be reserved
     in equivalent amount, is guilty of theft if he intentionally
     deals with the property obtained as his own and fails to make
     the required payment or disposition. The foregoing applies
     notwithstanding that it may be impossible to identify particular
     property as belonging to the victim at the time of the failure
     of the actor to make the required payment or disposition.
        (b)  Presumptions.--An officer or employee of the government
     or of a financial institution is presumed:
            (1)  to know any legal obligation relevant to his
        criminal liability under this section; and
            (2)  to have dealt with the property as his own if he
        fails to pay or account upon lawful demand, or if an audit
        reveals a shortage or falsification of accounts.
