Parties to the proceeding filed open briefs on July 20, 2012 and reply briefs on August 7, 2012. On September 26, 2012, San Jose Water Company filed a motion for interim rate relief so that if a decision was not reached by the end of 2012, San Jose Water Company would be allowed to adopt interim rates, effective January 1, 2013, until a decision is adopted. To date, a final decision has not been adopted and interim rates are currently in effect. Interim rates were set equal to fiscal year-end 2012 rates. Differences between interim rates and approved rates are tracked in a memorandum account and will be submitted for recovery or refund. On July 11, 2014, the CPUC issued a proposed decision in this application. The proposed decision recommends rate increases of $22,063, or 9.79% in 2013, $11,579, or 4.72% in 2014 and $15,356, or 6.02% in 2015. A proposed decision is only a recommendation from the assigned Administrative Law Judge and is not necessarily indicative of what will be adopted in the final decision. San Jose Water Company is currently reviewing the proposed decision and comments were due July 31, 2014. The earliest the proposed decision can be voted on by the CPUC is August 14, 2014. A final decision on this application is expected in the third quarter of 2014. On February 28, 2014, San Jose Water Company submitted Advice Letter No. 456. In this advice letter, San Jose Water Company notified the CPUC that San Jose Water Company was implementing conservation Tariff Rule 14.1. The CPUC's Rule 14.1 provides voluntary conservation measures for customers, focusing primarily on outdoor water use which accounts for 50% of a typical customer's water usage. In addition, San Jose Water Company requested the implementation of a MCMA to track all operational and administrative costs associated with the implementation of Rule 14.1 and implementation of a MCRAMA to track any revenue shortfall associated with the implementation of the 20% conservation goal. The advice letter was approved on March 21, 2014 and the Rule 14.1 voluntary conservation measures, the MCMA, and MCRAMA all went into effect on March 31, 2014. San Jose Water Company will record the impact of the MCRAMA and MCMA regulatory accounts once probability of recovery can be determined and collection can be assured within 24 months of the year-end the revenue is recorded. On May 23, 2014, San Jose Water Company filed Advice Letter No. 461 seeking authorization to increase revenue by $9,400, or approximately 3.6% to offset increases to SCVWD groundwater production charges and treated water charges. The CPUC authorized this increase, and the increase became effective on July 1, 2014. On October 3, 2013, CLWSC filed a rate case with the TCEQ. The filing contained a request for an average system-wide rate increase of 23.1%, or $2,400. With the exception of customers served within the City of Bulverde, the new rates became effective on December 2, 2013. Subsequently, effective March 1, 2014, a rate settlement agreement was reached with the City of Bulverde with rate increases being phased-in over a 28-month period. Prior to approval by the TCEQ, the new rates are subject to adjustment and refund for customers outside the City of Bulverde. A preliminary hearing in the matter for customers outside the City of Bulverde was completed on July 22, 2014, at which time an Administrative Law Judge allowed additional time until September 12, 2014 for the involved parties to attempt to reach a settlement. CLWSC has recognized the average 23.1% increase in accordance with ASC Topic 980 which provides guidance when a regulated entity is permitted to bill requested rate increases before the regulator has ruled on the request. If information becomes available that indicates it is probable that any of the average 23.1% rate increase will need to be refunded and the amount of refund can be reasonably estimated, a loss contingency shall be accrued. CLWSC has determined at this time that it is not probable that any of the rate increase will need to be refunded. Management does not anticipate that the final TCEQ decision will materially affect SJW Corp.'s financial position, results of operations or cash flows.
