BALANCING AND MEMORANDUM ACCOUNT RECOVERY PROCEDURES | Balancing and Memorandum Account Recovery Procedures San Jose Water Company established balancing accounts for the purpose of tracking the under-collection or over-collection associated with expense changes and the revenue authorized by the CPUC to offset those expense changes. San Jose Water Company also maintains memorandum accounts to track revenue impacts due to catastrophic events, certain unforeseen water quality expenses related to new federal and state water quality standards, energy efficiency, WCMA, drought surcharges, Monterey Water Revenue Adjustment Mechanism, and other approved activities or as directed by the CPUC. Balancing and memorandum accounts are recognized by San Jose Water Company when it is probable that future recovery of previously incurred costs or future refunds that are to be credited to customers will occur through the ratemaking process. In addition, in the case of special revenue programs such as the WCMA, San Jose Water Company follows the requirements of ASC Topic 980-605-25—“Alternative Revenue Programs” in determining revenue recognition, including the requirement that such revenues will be collected within 24 months of the year-end in which the revenue is recorded. A reserve is recorded for amounts SJW Corp. estimates will not be collected within the 24-month period. This reserve is based on the difference between authorized usage in the last general rate case decision and an estimate of actual usage over the recovery period, offset by applicable drought surcharges. In assessing the probability criteria for balancing and memorandum accounts between general rate cases, San Jose Water Company considers evidence that may exist prior to CPUC authorization that would satisfy ASC Topic 980 subtopic 340-25 recognition criteria. Such evidence may include regulatory rules and decisions, past practices, and other facts and circumstances that would indicate that recovery or refund is probable. When such evidence provides sufficient support, the balances are recorded in SJW Corp.'s financial statements. Based on ASC Topic 980-605-25, San Jose Water Company recognized regulatory assets of $5,863 and $12,624 due to lost revenues accumulated in the 2016 WCMA account for three and nine months ended September 30, 2016, respectively. These regulatory assets were offset by a regulatory liability in the amount of $5,863 and $12,624 for three and nine months ended September 30, 2016, respectively, created by Tariff Rule 14.1 drought surcharges collected during the same period as allowed for in Advice Letter 473A which was approved by the CPUC and became effective June 15, 2015. These amounts have been recorded in the 2016 WCMA row shown in the tables below. On June 28, 2016, San Jose Water Company filed Advice Letter 492 for a surcharge of $8,767 to true-up the difference between interim rates and 2015 General Rate Case authorized rates, which is expected to be collected during a 12-month recovery period once approved. The $8,767 of revenue was recorded in the 2015 General Rate Case true-up row for the nine months ended September 30, 2016 table below. This amount includes $185 related to water supply accounts that have previously been recorded and have been deducted from the appropriate row in the nine months ended September 30, 2016 table below.
