Revenue from contracts with customers The Company principally generates operating revenue from contracts with customers by providing regulated water and wastewater services at tariff-rates authorized by the Commissions in the states in which they operate and non-regulated water and wastewater services at rates authorized by contracts with government agencies. Revenue from contracts with customers reflects amounts billed for the volume of consumption at authorized per unit rates, for a service charge, and for other authorized charges. The Company satisfies its performance obligation to provide water and wastewater services over time as services are rendered. The Company applies the invoice practical expedient and recognizes revenue from contracts with customers in the amount for which the Company has a right to invoice. The Company has a right to invoice for the volume of consumption, for the service charge, and for other authorized charges. The measurement of sales to customers is generally based on the reading of their meters, which occurs on a systematic basis throughout the month. At the end of each month, the Company estimates consumption since the date of the last meter reading and a corresponding unbilled revenue is recognized. The estimate is based upon the number of unbilled days that month and the average daily customer billing rate from the previous month (which fluctuates based upon customer usage). Contract terms are generally short-term and at will by customers and, as a result, no separate financing component is recognized for the Company's collections from customers, which generally require payment within 30 days of billing. The Company applies judgment, based principally on historical payment experience, in estimating its customers’ ability to pay. Certain customers are not billed for volumetric consumption, but are instead billed a flat rate at the beginning of each monthly service period. The amount billed is initially deferred and subsequently recognized over the monthly service period, as the performance obligation is satisfied. The deferred revenue balance or contract liability, which is included in "accrued expenses and other liabilities" on the consolidated balance sheets, is inconsequential. In the following tables, revenue from contracts with customers is disaggregated by class of customers for the three and six months ended June 30, 2019 and 2018:
| Three Months Ended June 30
| 2019 |  | 2018
Residential | $ | 107,349 |  |  | $ | 109,849 |
Business | 31,706 |  |  | 32,125 |
Industrial | 7,524 |  |  | 7,941 |
Public authorities | 7,613 |  |  | 8,251 |
Other (a) | 13,275 |  |  | 13,606 |
Total revenue from contracts with customers | $ | 167,467 |  |  | $ | 171,772 |

Total revenue from contracts with customers | $ | 284,877 |  |  | $ | 306,026 |
(a) Other includes the accrued unbilled revenue. Regulatory balancing account revenue The Company’s ability to recover revenue requirements authorized by the California Public Utilities Commission (CPUC) in its triennial General Rate Case (GRC), is decoupled from the volume of the sales. Regulatory balancing account revenue is revenue related to rate mechanisms authorized in California by the CPUC, which allow the Company to recover the authorized revenue and are not considered contracts with customers. The Water Revenue Adjustment Mechanism (WRAM) allows the Company to recognize the adopted level of volumetric revenues. The variance between adopted volumetric revenues and actual billed volumetric revenues for metered accounts is recorded as regulatory balancing account revenue. Cost-recovery rates, such as the Modified Cost Balancing Account (MCBA), provide for recovery of the adopted levels of expenses for purchased water, purchased power, pump taxes, water conservation program costs, pension, and health care. Variances between adopted and actual costs are recorded as regulatory balancing account revenue. Each district's WRAM and MCBA regulatory assets and liabilities are allowed to be netted against one another. The Company recognizes regulatory balancing account revenues that have been authorized for rate recovery, are objectively determinable and probable of recovery, and are expected to be collected within 24 months. To the extent that regulatory balancing account revenue is estimated to be collectible beyond 24 months, recognition is deferred. Non-regulated Revenue The following tables disaggregate the Company’s non-regulated revenue by source for the three and six months ended June 30, 2019 and 2018:
| Three Months Ended June 30
| 2019 |  | 2018
Operating and maintenance revenue | $ | 3,273 |  |  | $ | 2,297 |
Other non-regulated revenue | 1,267 |  |  | 1,981 |
Non-regulated revenue from contracts with customers | $ | 4,540 |  |  | $ | 4,278 |
Lease revenue | $ | 590 |  |  | $ | 567 |
Total non-regulated revenue | $ | 5,130 |  |  | $ | 4,845 |
| Six Months Ended June 30
| 2019 |  | 2018
Operating and maintenance revenue | $ | 6,319 |  |  | $ | 5,462 |
Other non-regulated revenue | 2,563 |  |  | 2,724 |
Non-regulated revenue from contracts with customers | $ | 8,882 |  |  | $ | 8,186 |
Lease revenue | $ | 1,149 |  |  | $ | 1,078 |
Total non-regulated revenue | $ | 10,031 |  |  | $ | 9,264 |
Operating and maintenance services are provided for non-regulated water and wastewater systems owned by private companies and municipalities. The Company negotiates formal agreements with the customers, under which they provide operating, maintenance and customer billing services related to the customers’ water system. The formal agreements outline the fee schedule for the services provided. The agreements typically call for a fee-per-service or a flat-rate amount per month. The Company satisfies its performance obligation of providing operating and maintenance services over time as services are rendered; as a result, the Company employs the invoice practical expedient and recognizes revenue in the amount that it has the right to invoice. Contract terms are generally short-term and, as a result, no separate financing component is recognized for its collections from customers, which generally require payment within 30 days of billing. Other non-regulated revenue primarily relates to services for the design and installation of water mains and other water infrastructure for customers outside the regulated service areas and insurance program administration. Lease revenue is not considered revenue from contracts with customers and is recognized following operating lease standards. The Company is the lessor in operating lease agreements with telecommunications companies under which cellular phone antennas are placed on the Company's property. The company provides the lessee the right to ingress and egress across lessor property to access the antennas. The minimum rents are recognized on a straight-line basis over the terms of the leases, which may span multiple years. The excess rents are recognized over amounts contractually due pursuant to the underlying leases and is included in a deferred receivable account in the accompanying balance sheet. The leases generally have terms of 5 to 10 years, with lessee options to extend the lease for up to 15 years. The exercise of lease renewal options is at the lessee’s sole discretion. Most of the Company’s lease agreements contain mutual termination options that require prior written notice by either lessee or lessor. A subset of the Company’s leases contains variable lease payments that depend on changes in the consumer price index (CPI). The Company determines if an arrangement is a lease at inception. Generally, a lease agreement exists if the Company determines that the arrangement gives the lessee control over the use of an identified asset and obtains substantially all of the benefits from the identified asset. Maturities of lease payments to be received are as follows:
Year Ending December 31, | Operating Leases
2019 | $ | 3,095 |
2020 | 2,499 |
2021 | 1,827 |
2022 | 1,031 |
2023 | 554 |
Thereafter | 872 |

Cash and cash equivalents | 54,560 |  |  | 47,176 |
Restricted cash (included in "taxes, prepaid expenses and other assets") | 520 |  |  | 539 |
Total cash, cash equivalents, and restricted cash shown in the statements of cash flows | $ | 55,080 |  |  | $ | 47,715 |
Adoption of New Accounting Standards In February of 2016, the Financial Accounting Standards Board (FASB) issued guidance on leases, with amendments in 2018. The guidance requires lessees to recognize an asset and liability on the balance sheet for all of their lease obligations. Operating leases were previously not recognized on the balance sheet. The Company adopted the standard using the modified retrospective method for its existing leases and did not restate its comparative periods in the period of adoption. The Company completed its review of its lease portfolio including significant leases and the Company designed and implemented new controls as part of the adoption of the new standard. The implementation increased lease assets and lease liabilities on the Consolidated Balance Sheets by $13.8 million as of January 1, 2019. The Company elected certain practical expedients and carried forward historical conclusions related to (1) contracts that contain leases, (2) existing lease classification for any expired or existing leases, and (3) initial direct costs for any existing leases. The Company also applied the practical expedient that allows the Company to elect, as an accounting policy, by asset class, to include both lease and nonlease components as a single component and account for it as a lease. The Company applied the short-term lease exception which allowed the Company to not have to apply the recognition requirements of the new leasing guidance for short-term leases and to recognize lease payments in net income on a straight line basis over the lease term. Otherwise, the new standard did not have a material impact on the remaining consolidated financial statements.
