Melinda, the answer to your question is really state specific. You should find a criminal defense attorney in your state (see this web site) and consult with him or her. If the law of your state provides that after the expiration of the statute of limitations (say 5 years) has elapsed, then the charges are automatically dropped, you have nothing to worry about. But I do not know what your state's laws are about this matter. Next, you have to realize that even though you could theoretically pay back the company, that does not necessarily make the arrest warrant and charges dissappear. Your state may require that the defrauded company apply to the prosecutor for the charges to be dropped. Or the state law may give discretion to the prosecutor whether to drop the charges, assuming he could prove his case without the help of the defrauded party. Best luck to you.
