This excerpt taken from the SPH DEF 14A filed May 26, 2009.
Section 16(a) Beneficial Ownership Reporting Compliance
Section 16(a) of the Securities Exchange Act of 1934, as amended, requires our Supervisors, executive officers and holders of 10 percent or more of our Common Units to file initial reports of ownership and reports of changes in ownership of our Common Units with the Securities and Exchange Commission. Supervisors, executive officers and 10 percent Unitholders are required to furnish Suburban with copies of all Section 16(a) forms that they file. Based on a review of these filings, we believe that all such filings were timely made during fiscal 2008.
