In accordance with ASC 980, rates charged to utility customers are intended to recover the costs of the provision of service plus a reasonable return in the same period. Changes to the rates are made through formal rate applications with the ACC, which we have done for all of our operating utilities and which are described below.

On July 9, 2012, we filed formal rate applications with the ACC to adjust the revenue requirements for seven utilities representing a collective rate increase of approximately 28% over 2011 revenue levels. In August 2013, the Company entered into a settlement agreement with ACC Staff, the Residential Utility Consumers Office, the City of Maricopa, and other parties to the rate case. The settlement required approval by the ACC’s Commissioners before it could take effect. In February 2014, the rate case proceedings were completed and the ACC issued Rate Decision No. 74364, effectively approving the settlement agreement. The rulings of the decision include, but are not limited to, the following:

•For the Company’s utilities, adjusting for the condemnation of the operations and assets of Valencia and sale of Willow Valley Water Co., Inc. ("Willow Valley"), which occurred in 2015 and 2016, respectively, a collective revenue requirement increase of $3.6 million based on 2011 test year service connections, phased-in over time, with the first increase in January 2015 as follows (in thousands, not updated for the TCJA, refer to Note 1 — "Basis of Presentation, Corporate Transactions, Significant Accounting Policies, and Recent Accounting Pronouncements — Corporate Transactions — ACC Tax Docket" for further details):

Whereas this phase-in of additional revenues was determined using a 2011 test year, to the extent that the number of active service connections increases from 2011 levels, the additional revenues may be greater than the amounts set forth above. On the other hand, if active connections decrease or we experience declining usage per customer, we may not realize all of the anticipated revenues.

•Full reversal of the imputation of CIAC balances associated with funds previously received under ICFAs, as required in the Company’s last rate case. The reversal restored rate base or future rate base and had a significant impact of restoring shareholder equity on the balance sheet.

•The Company has agreed to not enter into any new ICFAs. Existing ICFAs will remain in place, but a portion of future payments to be received under the ICFAs will be considered as hook-up fees, which are accounted for as CIAC once expended on plant.

On September 20, 2018, the ACC issued Rate Decision No. 76901, which set forth the reductions in revenue for our Santa Cruz, Palo Verde, Greater Tonopah, and Northern Scottsdale utilities due to the TCJA. Rate Decision No. 76901 adopted a phase-in approach for the reductions to match the phase-in of our revenue requirements under Rate Decision No. 74364. Refer to Note 1 — "Basis of Presentation, Corporate Transactions, Significant Accounting Policies, and Recent Accounting Pronouncements — Corporate Transactions — ACC Tax Docket" for details regarding Rate Decision No. 76901.

On March 20, 2019, we filed a motion with the ACC to request an order for certain of our utilities to file a rate case. Thereafter, on April 26, 2019, the ACC issued Decision No. 77168, which requires all of our utilities to file a rate case no later than June 30, 2020, using the twelve months ending December 31, 2019 as the test year for the rate case. Refer to Note 1 — “Basis of Presentation, Corporate Transactions, Significant Accounting Policies, and Recent Accounting Pronouncements — Corporate Transactions — ACC Rate Case” for additional information.

Infrastructure Coordination and Financing Agreements – ICFAs are agreements with developers and homebuilders whereby GWRI, the indirect parent of the operating utilities, provides services to plan, coordinate, and finance the water and wastewater infrastructure that would otherwise be required to be performed or subcontracted by the developer or homebuilder.

Under the ICFAs, GWRI has a contractual obligation to ensure physical capacity exists through its regulated utilities for water and wastewater to the landowner/developer when needed. This obligation persists regardless of connection growth. Fees for these services are typically a negotiated amount per equivalent dwelling unit for the specified development or portion of land. Payments are generally due in installments, with a portion due upon signing of the agreement, a portion due upon completion of certain milestones, and the final payment due upon final plat approval or sale of the subdivision. The payments are non-refundable. The agreements are generally recorded against the land and must be assumed in the event of a sale or transfer of the land. The regional planning and coordination of the infrastructure in the various service areas has been an important part of GWRI’s business model.

deemed CIAC for rate making purposes. ICFA funds already received or which had become due prior to the date of Rate Decision No. 74364 were recognized as revenue once the obligations specified in the ICFA were met. Rate Decision No. 74364

prescribes that of the ICFA funds which come due and are paid subsequent to December 31, 2013, 70% of the ICFA funds will be recorded in the associated utility subsidiary as a hook-up fee (“HUF”) liability, with the remaining 30% to be recorded as deferred revenue, which the Company accounts for in accordance with the Company's ICFA revenue recognition policy. A HUF tariff, specifying the dollar value of a HUF for each utility, was approved by the ACC as part of Rate Decision No. 74364. The Company is responsible for assuring the full HUF value is paid from ICFA proceeds, and recorded in its full amount, even if it results in recording less than 30% of the ICFA fee as deferred revenue.

The Company will account for the portion allocated to the HUF as a CIAC contribution. However, in accordance with the ACC directives the CIAC is not deducted from rate base until the HUF funds are expended for utility plant. Such funds will be segregated in a separate bank account and used for plant. A HUF liability will be established and will be amortized as a reduction of depreciation expense over the useful life of the related plant once the HUF funds are utilized for the construction of plant. For facilities required under a HUF or ICFA, the utilities must first use the HUF moneys received, after which, it may use debt or equity financing for the remainder of construction. The Company will record 30% of the funds received, up until the HUF liability is fully funded, as deferred revenue, which is to be recognized as revenue once the obligations specified within the ICFA are met, including construction of sufficient operating capacity to serve the customers for which revenue was deferred.

As of both December 31, 2019 and December 31, 2018, ICFA deferred revenue recorded on the consolidated balance sheet totaled $17.4 million, which represents deferred revenue recorded for ICFA funds received on contracts that had become due prior to Rate Decision No. 74364.

Intangible assets / Regulatory liability – Pursuant to Rate Decision No. 74364, approximately 70% of ICFA funds to be received in the future will be recorded as a HUF, until the HUF is fully funded at the Company’s applicable utility subsidiary. The remaining approximate 30% of future ICFA funds will be recorded at the parent company level and will be subject to the Company’s ICFA revenue recognition accounting policy. As the Company now expects to experience an economic benefit from the approximately 30% portion of future ICFA funds, 30% of the regulatory liability, or $3.4 million, was reversed in 2014. The remaining 70% of the regulatory liability, or $7.9 million, will continue to be recorded on the balance sheet.

The intangible assets amortize when the corresponding ICFA funds are received in proportion to the amount of total cash expected to be received under the underlying agreements. The recognition of amortization expense will be partially offset by a corresponding reduction of the regulatory liability.

As of December 31, 2019, regulatory liability recorded on the consolidated balance sheet totaled $8.8 million, of which $7.6 million relates to the offset of intangible assets related to ICFA contracts obtained in connection with our Santa Cruz, Palo Verde, and Sonoran acquisitions, and the remaining $1.2 million relates to the TCJA rate reduction mandated by the ACC pursuant to Rate Decision No. 76901.
