Rate and Regulatory Matters	Note 2 – Rate and Regulatory Matters Middlesex – In March 2020, the NJBPU approved Middlesex’s petition to reset its Purchased Water Adjustment Clause (PWAC) tariff rate to recover additional costs of $0.6 million for the purchase of treated water from a non-affiliated water utility regulated by the NJBPU. The new PWAC rate became effective on April 4, 2020. A PWAC is a rate mechanism that allows for recovery of increased purchased water costs between base rate case filings. It is reset to zero once those increased costs are included in base rates. Tidewater - Effective July 1, 2020, Tidewater increased its DEPSC-approved Distribution System Improvement Charge (DSIC) rate, which is expected to generate revenue of approximately $0.5 million annually. A DSIC is a rate-mechanism that allows water utilities to recover investments in, and generate a return on, qualifying capital improvements made between base rate proceedings. Southern Shores - Effective January 1, 2020, the DEPSC approved the renewal of a multi-year agreement for water service to a 2,200 unit condominium community in Sussex County, Delaware. Under the agreement, current rates will remain in effect until December 31, 2024, but should there be unanticipated capital expenditures or regulatory related changes in operating expenses exceeding certain thresholds during this time period, rates are permitted to be adjusted to reflect such cost changes. Thereafter, rate increases, if any, cannot exceed the lesser of the regional Consumer Price Index or 3%. The new agreement expires on December 31, 2029. Twin Lakes - In March 2020, the Pennsylvania Public Utilities Commission (PAPUC) approved a $0.1 million increase in annualized base rates for Twin Lakes. In July 2019, Twin Lakes had filed a petition with the PAPUC seeking permission to increase annualized base rates by approximately $0.2 million, necessitated by capital infrastructure investments and increased operations and maintenance costs. The new rates became effective April 19, 2020. COVID-19 - The NJBPU and the DEPSC have allowed for potential future recovery in customer rates of additional costs related to COVID-19 (for further discussion of the impact of COVID-19 on the Company, see Note 1- Basis of Presentation and Recent Developments, Recent Developments).
