acquisition added approximately 1,700 water customers and nearly 2,000 wastewater customers.
The Tex as assets served approximately 4,200 water and 1,100 wastewater customers in the greater Houston metropolitan area.
As noted above, as a result of these sales, these regulated subsidiaries are presented as discontinued operations for all periods presented.
Therefore, the amounts, statistics and tables presented in this section refer only to on-going operations, unless otherwise noted.
The following table sets forth our Regulated Businesses operating revenue for 2013 and number of customers from continuing operations as well as an estimate of population served as of December 31, 2013:
## Table 0 ##
(a) Includes Illinois-American Water Company, which we refer to as ILAWC and American Lake Water Company, also a regulated subsidiary in Illinois.
(b) West Virginia-American Water Company, which we refer to as WVAWC, and its subsidiary Bluefield Valley Water Works Company.
(c) Includes data from our operating subsidiaries in the following states: Georgia, Hawaii, Iowa, Kentucky, Maryland, Michigan, New York, Tennessee, and Virginia.
Approximately 87.5 % of operating revenue from our Regulated Businesses in 2013 was generated from approximately 2.7 million customers in our seven largest states, as measured by operating revenues.
In fiscal year 2013, no single customer accounted for more than 10% of our annual operating revenue.
Overview of Networks, Facilities and Water Supply Our Regulated Businesses operate in approximately 1,500 communities in 16 states in the United States.
Our primary operating assets include 87 dams along with approximately 80 surface water treatment plants, 500 groundwater treatment plants, 1,000 groundwater wells, 100 wastewater treatment facilities, 1,200 treated water storage facilities, 1,300 pumping stations, and 47,000 miles of mains and collection pipes.
Our regulated utilities own substantially all of the assets used by our Regulated Businesses.
We generally own the land and physical assets used to store, extract and treat source water.
Typically, we do not own the water itself, which is held in public trust and is allocated to us through contracts and allocation rights granted by federal and state agencies or through the ownership of water rights pursuant to local law.
Maintaining the reliability of our networks is a key activity of our Regulated Businesses.
We have ongoing infrastructure renewal programs in all states in which our Regulated Businesses operate.
These programs consist of both rehabilitation of existing mains and replacement of mains that have reached the end of their useful service lives.
Our ability to meet the existing and future water demands of our customers depends on an adequate supply of water.
Drought, governmental restrictions, overuse of sources of water, the protection of threatened species or
The following table summarizes the changes in the Company’s valuation allowance:
## Table 1 ##
Included in 2013 is a discrete tax benefit totaling $2,979 associated with an entity re-organization within the Company’s Market-Based segment that allowed for the utilization of state net operating loss carryforwards and the release of an associated valuation allowance.
Note 14: Employee Benefits Pension and Other Postretirement Benefits The Company maintains noncontributory defined benefit pension plans covering eligible employees of its regulated utility and shared services operations.
Benefits under the plans are based on the employee’s years of service and compensation.
The pension plans have been closed for all employees.
The pension plans were closed for most employees hired on or after January 1, 2006.
Union employees hired on or after January 1, 2001 had their accrued benefit frozen and will be able to receive this benefit as a lump sum upon termination or retirement.
Union employees hired on or after January 1, 2001 and non-union employees hired on or after January 1, 2006 are provided with a 5.25% of base pay defined contribution plan.
The Company does not participate in a multiemployer plan.
The Company’s pension funding practice is to contribute at least the greater of the minimum amount required by the Employee Retirement Income Security Act of 1974 or the normal cost.
Further, the Company will consider additional contributions if needed to avoid “at risk” status and benefit restrictions under the Pension Protection Act of 2006.
The Company may also consider increased contributions, based on other financial requirements and the plans’ funded position.
Pension plan assets are invested in a number of actively managed and indexed investments including equity and bond mutual funds, fixed income securities, guaranteed interest contracts with insurance companies and real estate investment trusts (“REITs”).
Pension expense in excess of the amount contributed to the pension plans is deferred by certain regulated subsidiaries pending future recovery in rates charged for utility services as contributions are made to the plans.
(See Note 6) The Company also has unfunded noncontributory supplemental non-qualified pension plans that provide additional retirement benefits to certain employees.
The Company maintains other postretirement benefit plans providing varying levels of medical and life insurance to eligible retirees.
The retiree welfare plans are closed for union employees hired on or after January 1, 2006.
The plans had previously closed for non-union employees hired on or after January 1, 2002.
The Company’s policy is to fund other postretirement benefit costs for rate-making purposes.
Assets of the plans are invested in equity mutual funds, bond mutual funds and fixed income securities.
The following table sets forth the amounts and percentages of Regulated Businesses’ revenues and billed water sales volume by customer class:
## Table 2 ##
Water Services—Consistent with the above discussion, water service operating revenues for the year ended December 31, 2013 totaled $2,465.0 million, a $21.3 million increase, or 0.9%, over the same period of 2012.
However, the mix between billed revenues/billed volumes to unbilled revenues/unbilled volumes have changed significantly principally as a result of our CIS implementation.
Unbilled revenue has increased $25.7 million compared to the same period in the prior year mainly as a result of delayed invoicing to customers.
With the implementation, we made a decision to increase the level of scrutiny and verification around bills being generated by the new system, in particular larger and/or more complex bills.
As such bills that exceed certain tolerance levels are being held until verification can be performed.
As such, the timing of issuance of bills has caused a decrease in billed volumes in 2013 when compared to 2012, with a corresponding increase in unbilled usage.
For our residential and commercial customers, we believe that the majority of the decline in billed volumes is attributable to the weather abnormalities between 2012 and 2013 as well as the implementation of our new CIS system by our regulated subsidiaries.
For the remaining customer classes, we believe the decline in billed volumes is mainly due to the delay in invoicing the customer as a result of our CIS implementation.
Wastewater services—Our subsidiaries provide wastewater services in 10 states.
Revenues from these services increased by $4.7 million, or 6.0%, to $82.8 million for the year ended December 31, 2013, from the same period of 2012.
The increase was primarily attributable to rate increases in our Pennsylvania subsidiary as well as the Dale acquisition in November, 2013.
Other revenues—Other revenues, which includes such items as reconnection charges, initial application service fees, certain rental revenues, revenue collection services for others and similar items, increased $3.5 million, or 8.2%, compared to the year ended December 31, 2012.
The increase in revenues for the year ended December 31, 2013 as compared to the same period in the prior year was mainly due to the additional surcharge revenues offset by decreases in revenues related to billings for others, reconnection and late fees.
units with performance conditions vest ratably over the three-year performance period beginning January 1 of the year of grant (the “Performance Period”).
Distribution of the performance shares is contingent upon the achievement of internal performance measures and, separately, certain market thresholds over the Performance Period.
During 2014, 2013 and 2012, the Company granted restricted stock units to non-employee directors under the Plan.
The restricted stock units vested on the date of grant; however, distribution of the shares will be made within 30 days of the earlier of (a) 15 months after grant date or (b) the participant’s separation from service.
Because these restricted stock units vested on grant date, the total grant date fair value was recorded in operation and maintenance expense included in the expense table above on the grant date.
Restricted stock units generally vest over periods ranging from one to three years.
Restricted stock units granted with service-only conditions and those with internal performance measures are valued at the market value of the Company’s common stock on the date of grant.
Restricted stock units granted with market conditions are valued using a Monte Carlo model.
Expected volatility is based on historical volatilities of traded common stock of the Company and comparative companies using daily stock prices over the past three years.
The expected term is three years and the risk-free interest rate is based on the three-year U. S.  Treasury rate in effect as of the measurement date.
The following table presents the weighted-average assumptions used in the Monte Carlo simulation and the weighted-average grant date fair values of restricted stock units granted during the years ended December 31, 2014, 2013 and 2012:
## Table 3 ##
The grant date fair value of restricted stock awards that vest ratably and have market and/or performance and service conditions is amortized through expense over the requisite service period using the graded-vesting method.
Restricted stock units that have no performance conditions are amortized through expense over the requisite service period using the straight-line method.
As of December 31, 2014, $4,634 of total unrecognized compensation cost related to the nonvested restricted stock units is expected to be recognized over the weightedaverage remaining life of 1.4 years.
The total grant date fair value of restricted stock units vested during the years ended December 31, 2014, 2013 and 2012 was $10,829, $8,891 and $4,191, respectively.
The table below summarizes restricted stock unit activity for the year ended December 31, 2014:

The following table summarizes additional information regarding restricted stock units distributed during the years ended December 31, 2014, 2013 and 2012:
