These results represent an all time high for second quarter earnings. Operating revenue increased $6,035,000 from 1996 to $55,083,000. Weather, rate increases and new customers each contributed to the revenue increase. Consumption levels, as measured by average sales per metered customer, increased 11% during the quarter due to drier and warmer weather throughout the period. Revenue benefited from the general rate increase, which was effective June 11, 1996, and covered five districts and 47% of the Company's customers. A breakdown of the increase in operating revenue is accounted for in the following table: General rate increases $1,960,000 Step rate increases 409,000 Offset rate increases 158,000 Total rate increases 2,527,000 Increased consumption 3,096,000 Usage by 3,108 new customers 412,000 Net revenue increase $6,035,000 Total operating expenses increased 7% this year. Water production for the quarter was 9% above last year's level. Well production provided 54% of the supply with 46% purchased from wholesale suppliers. Water production costs, which includes purchased water, purchased power and pump taxes, decreased $670,000 despite the increase in water production. Purchased water refunds totaling $2,524,000 were received from two wholesale suppliers and credited to purchased water costs during the quarter, offsetting the additional production costs, and wholesale water suppliers' rate increases that became effective in five districts since last year. The components of water production expense and the changes from last year are shown in the table below: Second Quarter Dollar	 1997 Cost Change		 Purchased water $13,004,000 ($1,041,000) Purchased power 3,637,000 118,000	 Pump taxes 1,495,000 253,000	 Total $18,136,000 ($670,000) Other operations expense increased $1,276,000, primarily due to the impact of the 3.0% general wage increase which was effective at the start of the year and increases in related employee benefits. Customer accounting expense increased due to the timing of certain purchases. The California Public Utilities Commission reimbursement fee, which is based on 1-1/2% of billings, was greater due to additional customer billings. Depreciation and amortization expense increased $249,000 due primarily to increased depreciation expense authorized by the Commission in the rate case decision received in June 1996 affecting five districts. The additional expense is reflected in customer rates. Federal and state income taxes increased $1,708,000 because of greater taxable income. The California tax rate decreased from last year's 9.3% to 8.84% this year. REGULATORY MATTERS In July 1997, the Company filed its 1997 rate case applications with the California Public Utilities Commission (Commission) for rate increases in four districts representing 7% of total customers. The applications request additional annual revenue of about $650,000. In early February 1997, hearings before the Commission regarding the 1996 rate case filings were completed and a decision regarding the application was received from the full Commission in April. The Commission's decision authorized a 10.35% return on common equity. The decision is expected to increase 1997 revenue by about $2.5 million. LIQUIDITY Interest expense on long-term debt decreased by $62,000 as a result of the retirement of Series K first mortgage bonds and sinking fund payments made in the fourth quarter of 1996. Short-term interest expense increased $73,000 due to additional borrowings under the Company's bank line of credit during the current quarter. At June 30, 1997, $3.5 million was borrowed under the bank line of credit at an effective interest rate of 6.9%. During the quarter, the bank line of credit was renewed for a two year period with the maximum amount available to the Company under the arrangement increased to $50 million from $30 million. The second quarter common dividend was paid on May 15, 1997, at $0.5275 per share. The $0.5275 represents a $0.0075 increase in the quarterly dividend rate from last year as approved by the Board of Directors at their January meeting. Annualized, the dividend rate is $2.11 per common share. Based on the 12 month earnings per share at June 30, 1997, the dividend payout ratio is 56%. About 11% of the outstanding shares participate in the Company's Dividend Reinvestment Plan (Plan). No new common shares were issued under the Plan during the second quarter. Shares required for the Plan were purchased on the open market and redistributed to Plan participants. Book value per common share was $25.25 at June 30, 1997, compared to $23.58 a year earlier. During the quarter, utility plant expenditures totaled $7,046,000 for additions to and replacements of utility plant. Of that amount, $3,718,000 was funded through the Company's construction budget with the balance consisting of funds received from developers as contributions in aid of construction and refundable advances for construction. The 1997 Company construction budget is $23,200,000.	 The Indian Springs Mutual Utility Company's 187 customer water system was acquired during the quarter. The system is operated as part of the Salinas district. The Company had been operating the system for several months prior to completing the acquisition. HOLDING COMPANY FORMATION Progress continues to be made on formation of the holding company structure as authorized by the shareholders at their annual meeting. In conjunction with formation of the holding company, the Company's common stock will be split on a two-for-one basis and the Series C preferred stock's voting rights adjusted proportionately. Regulatory approval for adoption of the holding company is anticipated to be received in this year's fourth quarter. WATER SUPPLY The Company believes that its various sources of water supply are sufficient to meet customer demand for the remainder of the year. Historically, approximately half of the water source is purchased from wholesale suppliers with the other half pumped from wells. Storage in state reservoirs was 116% of historic average as of May 31, 1997, and groundwater levels remain adequate. PART II OTHER INFORMATION Item 4.
