Regulated Operations [Abstract]
Rate and Regulatory Matters	Note 2 – Rate and Regulatory Matters Middlesex – In June 2014, Middlesex’s application with the New Jersey Board of Public Utilities (NJBPU) seeking permission to increase base water rates was partially approved, granting an increase in annual operating revenues of $4.2 million. The originally-filed base water rate increase request of $10.6 million (subsequently revised to $8.1 million, primarily resulting from lower employee benefit plan costs), filed in November 2013, was necessitated by capital investments Middlesex had made, or committed to make, increased operations and maintenance costs and lost revenues resulting from the ending of a wholesale water sales contract with the Borough of Sayreville, New Jersey in August 2013 and Middlesex’s largest retail water customer, Hess Corporation, ceasing its oil refining operations at its Port Reading, New Jersey facility in February 2013. The new base water rates are designed to recover the increased costs, lost revenues, as well as a return on invested capital in rate base of $208.6 million based on a return on equity of 9.75%. The rate increase became effective on July 20, 2014. In May 2014, Middlesex filed a petition with the NJBPU seeking approval of foundational capital project information (Foundational Filing) that would allow for the implementation of a Distribution System Improvement Charge (DSIC). A DSIC is a rate-mechanism that allows water utilities to recover investment in capital improvements to their water distribution system made between base rate proceedings. If approved, the DSIC would increase annual revenues in increments occurring at approximate six-month intervals over a period of thirty-six months. The maximum annual revenues to be recovered under the Foundational Filing are $3.6 million. A decision by the NJBPU is expected in August 2014. We cannot predict whether the NJBPU will ultimately approve, deny, or reduce the capital projects submitted for consideration. Tidewater - In November 2013, Tidewater filed an application with the Delaware Public Service Commission (DEPSC) seeking permission to increase its base water rates by approximately $3.9 million per year. The request was necessitated by capital investments Tidewater has made, or has committed to make, as well as increased operations and maintenance costs. On July 2, 2014, Tidewater filed additional information that resulted in reducing its original request to $2.5 million, primarily from lower employee benefit plan costs. We cannot predict whether the DEPSC will ultimately approve, deny, or reduce the amount of the revised request. A decision by the DEPSC is expected in the third quarter of 2014. In connection with the rate increase application, Tidewater implemented a DEPSC approved 6.5% interim rate increase, subject to refund, on February 6, 2014. As of June 30, 2014, Tidewater has deferred $0.5 million of the interim rate increase in the event that the final approved rate increase is less than the approved interim rate increase. Concurrent with Tidewater’s interim rate increase, Tidewater’s DEPSC approved $0.1 million annual DSIC rate reset to $0. In April 2014, the DEPSC approved Tidewater’s agreement with the United States Department of Defense for the privatization of the water system of Dover Air Force Base (DAFB) in Dover, Delaware. Under the agreement, Tidewater will provide DAFB with potable water service and integrate the DAFB water system into its regulated utility operations. Tidewater expects to begin providing water service to DAFB in October 2014. Service to DAFB is expected to initially generate approximately $0.6 million of revenue annually. TESI - The DEPSC approved an April 2014 request by TESI to relinquish its Certificate of Public Necessity and Convenience (“CPCN”) for a real estate parcel in Sussex County, Delaware. This approval allowed for a companion transaction to be completed, whereby TESI was reimbursed with a combination of cash and a future receivable by a real estate developer for $1.9 million of Preliminary Survey and Investigation Costs incurred in connection with the CPCN. TESI recognized a gain of less the $0.1 million from this transaction.
