~ii containing post-consumer waste <<, 2016SMUD

FROM THE CEO J BY THE USUAL MEASURING STICKS, SMUD enjoyed a banner year in 2015.

We continued to provide the region's residences and businesses with depend-able and safe electricity. We kept our cost for electricity among the lowest in the state while adding more renewable resources to our power mix and reducing our carbon footprint. No other electric utility in the country had a higher customer satisfaction score in J.D. Power's annual survey of business customers.

The financial statements in this report show an organization on strong footing. SMUD's net income in 2015 was $56 million higher than planned, and our credit ratings are the strongest they've been in the last 30 years.

In other words, SMUD did what our customers and community expected us to do. But that's no longer enough . Customer expectations are changing rapidly, as are industry trends toward cleaner energy resources such as community solar, rooftop solar and storage . Just as they have come to expect convenient choices from their cell-phone providers and online retailers, the same SMUD customers who previously cared on ly about affordable and reliable electricity now want more choices and options in how they use and pay for their power.

Shortly after being appointed CEO and general manager by the SMUD Board in 2014, I laid out a vision called SMUD 3.0. The objective was to reshape SMUD into an organization capable of responding to new technologies, rising customer expectations, third -party entrants into the energy marketplace, data analytics, and post-2020 No other electric utility in the country carbon goals. These challenges to our historic way of had a higher customer satisfaction doing business arrived even faster than we expected .

score in J.D. Power's annual survey continued of business customers.

CEO CONTINUED In 2015, to make these objectives more understandable to our workforce, we created a North Star to focus our resources and investments over the next few years. The objective of the North Star is to identify a set of guiding principles that coalesce with SMUD's key priorities through 2020 . More than simply establishing a set of aspirational values, the six points identify clear metrics and desired outcomes to gauge our progress .

The six points are:

• Be safe. Always.

• Treasure our employees.

• Operational excellence.

• Value our customers and community.

• Financially fit.

• Sustainable future.

The North Star is centered inside the organization to create alignment and common purpose . It's not intended to be a marketing campaign or advertising slogan. This report presents some examples of how these principles are creating value for our customers and community.

SMUD will celebrate its 70th anniversary on the final day of 2016 . I'm confident that we'll be able to look back on steps we took in 2015 as being instrumental in providing customers with the tools and services they need to take greater control of their energy use while ensuring that SMUD embraces the new energy future in a progressive fashion.

Sincerely, Arle n O rchar d I CEO & Genera l Manager, SMUD

developed a set of guiding principles to help employees keep their eyes fixed on the future. The six points of the North Star are listed at right.

The following pages illustrate the varied ways in which these principles are being put into practice ... the ways in which SMUD is moving forward.

(Spoiler alert: In one example, beasts of burden were enlisted to help.)

SUSTAINABLE FUTURE Keeping the dams and powerhouses in SMUD's Upper American River Project in working order is essential to meeting the heavy summer demand for electricity.

Given the remote location of some of these hydroelectric facilities, a pioneer spirit sometimes comes in handy.

Consider the project SMUD undertook last year to install a new weir and dam valve in the far reaches of the Sierra Nevada wilderness.

The weir and valve projects didn't present any singular engineering or technical challenges for the 30 SMUD employees and contractors involved in the work. But extended stays in the remote backcountry did require some creative planning - such as enlisting the services of 20 mules and four mule handlers.

A valve weighing 2,300 pounds, along with two genera-tors weighing about the same, needed to be transported to SUSTAINABLE FUTURE I The Upper the 6,3so-foot elevation of Rubicon Reservoir.

SMUD's Upper American Rive r Project (UARP) is a 688-m egawatt hydroelectric system in the Eldorado National Forest. The UA RP's 11 dams and eight powerhouses produce enough clean, economical power to meet up to 15 percent of SMUD's power needs Extended stays in the remote backcountry did in a typical water year. require some creative planning - such as enlisting the services of 20 mules and four mule handlers.

THE YEAR ENDED with an above-average snowpack in the Sierra Nevada, raising spirits after four years of drought. December precipi-tation at Fresh Pond, headquarters of SMUD's hydroelectric operations, was 15.7 inches, well above the historical average of 9.1 inches.

The turnaround was cause for much relief.

A study of tree-ring data indicated that the 2014-15 winter snowpack in the Sierra was the thinnest in the last 500 years. The Upper American River Project is SMUD's most economical energy source, capable of satisfying roughly conditions. Dry years such as the previous four force SMUD to 15 percent of its annual power needs, given average water replace lost hydroelectric generation with more expensive power.

New online offerings Building stronger business ties SMUD GREATLY ENHANCED its online offerings for TO BETTER SERVE its commercial and industrial customers, customers in 2015 by adding a "My Energy Tools" feature SMUD implemented several changes making it easier to do to the "My Account" portal of smud.org.

VALUE OUR CUSTOMERS AND COMMUNITY The Sacramento Kings wanted their new downtown arena to be one of the greenest in the world.

SMUD was happy to help.

The Kings agreed to a 20-year SolarShares* partnership in which 85 percent of Golden 1 Center's electricity will be generated by SMUD at a new 10.9-megawatt photovoltaic plant at Rancho Seco in southeastern Sacramento County.

The SolarShares agreement with the Kings will keep nearly 2,000 tons of greenhouse gas out of the atmosphere.

The remaining 15 percent of the Golden 1 Center's power supply will come from solar panels installed on the roof of the arena.

The building was placed on the National Register of Historic Places in 2010 as an example of the Modern International Style of architecture.

The renovation will maintain the historic register standing and protect "Water City," the iconic mural by Sacramento artist Wayne Thiebaud that graces the front of the building.

Construction is scheduled to begin in the summer of 2016. The approximately 600 SMUD employees who worked in the Headquarters were relocated until the project is completed.

The renovation project will commit at least 25 percent of its contracting work to local fi.rms through SMUD's small business supplier program.

SMUD tops in business customer survey SMUD TIED for the highest score in the country among 86 electric utilities in the latest J.D. Power and Associates survey of business customers.

damaged equipment.

SMUD security officers attend numerous community events to educate the public about public safety. SMUD also offers a variety of safety resources for K- 12 teachers and students, including printed materials, workshops, virtual field trips and online games and activities for kids.

One of SMUD's biggest events in 2015 had a strong safety component. The American Public Power Association's Lineworkers Rodeo that SMUD hosted in May at Gibson Ranch showcased the high-wire work that utility workers carry out every day.

Performing their tasks safely counted just as much as doing it quickly for the Rodeo's 300 apprentices and journeymen from 16 states. The hurtman rescue simulated the rescue of an injured co-worker. In the apprentice category, one lineworker climbs a 40-foot pole and safely lowers a mannequin to the ground. In the journeyman classification, three team members coordinate the tasks of climbing, opening the switch and safely guiding the mannequin onto a tarp on the ground.

SMUD lineworkers swept the hurtman rescue events at the 2015 APPA Rodeo. Bryan Herda! won the apprentice division, and top journeyman honors went to the team of Cayleb Bowman, Matthew Wilson and Todd Prangley.

'

Nature,of Operations Under provisions of California's Mµnicipal Utility District Act, the citizens of Sacramento voted in 1923 to

.form their own electric utility - SMUD. The independently run community-owned utility began operations on

• December 31, 1946 and is n_ot subject to regulation or oversi~ht by the California Public Utilities Commission.

It is now the sixth largest.community-owned electric utility in the nation.

Governed by an elect~d board of directors (Board), SMUD has the rights and powers to fix rates and charges for commodities and services it furnishes, incur indebtedness, and issue bonds or other obligations. SMUD is responsible for the acquisition, generation, transmission and distribution of electric power to its service area with a

• population of approximately 1.4 million - most of Sacramento County and small, adjoining portions of-Placer and Yolo counties. Its purpose is to provide solutions for meeting customers' electrical energy needs with a vision of empowering customers with solutions and options that increase energy efficiency, protect the environment, reduce global warming, and lower the cost to serve the region.

The Board has independent authority to set SMUD's rates and charges. Changes in rates require a public hearing and formal action by the Board. In August 2013, the Board approved a 2.5 percent rate increase effective January 1, 2014, and an additio~al 2.5 percent rate increase effective January 1, 2015. The rate increases were designed to achieve a fixed charge ratio of at least 1.5. In July 2015, the Board approved another 2.5 percent rate increase for

.both 2016 and 2017 to allow for additional investments in technology and infrastructrire. The Board also approved an optional residential Time of Use (TOU) rate that would be made available in 2016 and 2017 and declared its.

Sacramento Municipal Utility District I 2015 Annu~I Report '

MANAGEMENT'S DISCUSSION AND ANALYSIS (Unaudited) intent to make TOU rates the standard for residential customers in lOl 8. The TOU rate structure puts SMDP at the industry forefront by setting the stage to better align rates with the actual cost of electricity.' Even with these increases, SMUD's rates continue to remain amongst the lowest in the state. In 2015, the average system rate was 25.7 percent below the ne~rest investor owned utility's average rate.

SMUD's ".ision is to be the trusted partner with its customers and the community, providing innovative solutions to ens_ure energy affordability and reliability, improve the environment, red.uce our region's carbon footprint, and enhance the vitality of our community. SMUD's business strategy focuses on serving its customers in a progressive, forward looking manner, addressing current regulatory and legislative*issues and potential competitive forces. This includes 'ensuring financial stability' by establishing rates that provide acceptable cash coverage of all fixed charges on a consolidated basis, taking into con~ideration the impact'of capital expenditures and other factors on cash flow.

Financial & Operational Highlights

. - .

In 2015, SMUD continued working toward realizing the vision of meeting increased customer_expectations and improving operation~! efficiencies. In April 2015, SMUD's bonds were upgraded by Moody's.from Al to Aa3 and as a result, SMUD is now experiencing the strongest bond ratings in almost 30 years by all three major rating agencies. SMUD was recognized by its residential customers as the top California utility for the fourteenth consecutive year by J.D. Power !ind was ranked first among midsize utilities in the West and No. 1 in California for the tenth consecutive year for business customer satisfaction. Negotiations were completed for the development and power purchase of 10.88 MW solar project at the decommissioned Rancho Seco nuclear plant site whiCh will

• supply renewable ~nergyfor the commercial SolarShares program. The first commercial SolarShares offering was launched as a result of complet~ng a 20-year agreement with the Sacramento Kings and the California Department of General Services. This agreement will help cre~te one of the lightest environmental footprints of any arena in the*u.s. by meeting LEED Gold st~ndards. SMUD was awarded the Diamond Member_ Reliable Public Power Provider designation (Diamond RP3), the highest possible designation from the American Public Power Association (APPA) for delivering reliable and safe electric services and also hosted the 2015 APPA Lineworkers Rodeo.

Other accomplishments include celebrating 25 years of a partnership that has resulted in providing more than a ha~fmillion free shade trees to residences and businesses since 1990, the development of the SMUD Power.

Academy with state certification for seven apprentice training programs, and relocating all employees from the

, headquarters building in preparation for its renovation. Through its economic development program, SMUD played a key role in. the attraction, retention and expansion of several companies in its service territory which led

• to the creation of over 1,800 jobs.

In July 2014, FERC issued a new fifty year license for the Upper American River Project (UARP), which included authority to build the Iowa Hill pumped-storage project. The UARP consists of three relatively large storage*

r~servoirs and eig~t powerhouses containing eleven turbines. The UARP is one of SMUD's lowest cost power sources. In addition to providing clean hydroelectric power and operational flexibility, it provides habitat for fisl).

and wildlife ap.d a variety of recreational opportunities, including camping, fishing, boating, hiking, horseback riding, mountain biking, and cross-country skiing. The combined capacity of the UARP is approximately 673 megawatts (MW) and represents about 15 percent _of SMUD's average annual retail energy requirements. The Iowa Hill pumped-storage project was a proposed 3 unit, 400 MW variable speed powerhouse. The first phase of the

'ge"otechnical exploration plan and most of the required permitting was completed in 2014. In Dec~mber 2015, -

after much analysis, SMUD made the decision to terminate the Iowa Hill pumped-storage project as it was determined to no longer be financially feasible (Board approved February 2016). SMUD's other power generation facilities include 3 MW of solar photovoltaic installations, *the 102 MW Solano Wind Project, a~d five local gas-ffred power plants with total capacity of approximately 1,012 MW In addition, SMUD has several power purchase agreements to help meet its remaining power requir.ements.

\

Sacramento Municipal Utility District I 2015 Annual Report MANAGEMENT'S DISCUSSION AND ANALYSIS (Unaudited)

As part of_the hydro relicensing process, SMUD ent~red into iong-term contracts to provide certain services to four different government agencies - U.S. Department of Interior Bureau of Land Management, U.S. Department of Agriculture Forest Service, El Dorado County, and the California Department of Parks and Recreation. The aggregate present value of all contract payments of $56.1 million was recorded as a Noncurrent Liability at Dece~ber 31, 2014. The balance oft~e Liability at December 31, 2015 was $55.0 million.

The impact of the drought continued to plague California in 2015. SMUD experienced a-fourth year of below average precipitation, which reduced its hydroelectric generation from the UARP by more than 50 percent.

A Hydro Rate Stabilization Fund (HRSF) was established to help absorb higher energy costs when hydroelectric production is down and to serve as a-buffer against unexpected financial developments. In April 2015, the

$3.l million remaining balance was transferred from the HRSF as a result of the lower precipitation. In 2014, *

$24.3 million was also transferred from the HRSF due to lower precipitation. The zero balance in the HRSF at December 31, 2015 is an indicator of the significant cumulative effect of the drou,ght over the last few years-.

Although SMUD's.mitigation efforts have protected its rate payers from rate volatility due to higher operating costs, it was determined that the reserves were not adequate to cover all costs. Accordingly, in Ap_ril 2015, SMUD applied an automatic 12-month Hydro Generation Adjustment (HGA) surcharge of 1.3 percent to its customers' electric bills.

SMUD also has a long-term agreement with the Western Area Power Administration (WAPA) to purchase power generated by the Central Valley Project, a series of federal hydroelectric facilities operated by the U.S. Bureau of Reclamation. .SMUD uses a Rate Stabilization Fund (RSF) to offset

, .

any excess or deficits

. -in WAPA energy deliveries. As a result of the drought, WAPA's deliveries fell short by about 54 percent and in December 2015,

$12.0 million \\'.as transferred from the RSF due to the lower energy deliveries. In December 2014, $11.8 million was transferred from the RSF d~e to energy deliveries falling short in that year as well. At December 31, 2015 and 2014, the balance of the RSF \\'as $30.3 million and $42.3 m~llion, respectively.

Decommissioning During 2014, SMUD made significant progress toward completing the Decominissioning Plan for its Rancho Seco nuclear facility, which was shut down in 1989. The plan consists of two phases that allow SMUD to terminate its possession-only license. Ph~se I of the decommissioning was completed at the end of 2008. P~ase II consists of a storage period for the Class B and Class C radioactive waste overseen by the existing facility staff,_ followed by shipment of the waste for disposal, and then complete termination of the possession-only licel)se. SMDD also established. and funded an external decommissioning trust fund as part of its assurance to the Nuclear Reg1:11a~ory

~ommission (NRC) to pay for the cost of decommissiqning. In September-2013, SMUD entered into a contract with the operator ofa low-level radioactive waste facility located in Andrews, Texas. Shipme1;1t of the previously stored Class Band Class C radioactive waste was completed in November 2014. The disposal and shipment costs totaling over $22.0 million were funded from the decommissioning trust fund. The remaining Phase II decommis~ioning activities that will lead to termination of the possession-only license began during 2015 and license termination activiti~s are e_xpected to be completed by the el)d of2016. No funds were withdrawn from the decommissioning trust fund during 2015; therefore the balance remained at $_8.3 million as of December 31, 2015 and 2014. The Accrued Decommissioning balance in the Consolidated Statements of Net Position includes

$150.4 and $152.1 million for costs related to Rancho Seco as of December 31, 2015 and 2014, respectively.

As part of the Decommissioning Plan, the nuclear fuel and Greater Than Class C (GTCC) radioactive waste is being stored in a dry storage facility constructed by SMUD and licensed separately by the NRC. The U.S. Department of Energy (DOE), under the Nuclear Waste Policy Act of 1982, was responsible f9r permanent disposal of used nuclear fuel and GTCC radioactive waste and SMUD contracted with the DOE for removal.and disposal of that

Sacramento Municipal Utility District I 2015 Annual Report MANAGEMENT'S DISCUSSION AND ANALYSIS (Unaudited) waste. In 1998, SMUD filed suit against the DOE for breach-of-contract because the DOE never provided a permanent waste disposal site. In September 2014 aud February 2015, $MUD received awards for $53.1 million I

and $22.5 million, respeqtively, from the U. S. Court of ClailIJ.S which was recorded as Other ln<<_ome - Net in the Consolidated Statements ofReve~ues, Expenses and Changes in "Net Position. In-June 2015, SMUD filed a suit against DOE which covered the costs*incurred from 2010 through at least June 2015.

Employee Relations and Benefits

• Effective January 1, 2013, SMUD began operating under a new five year mem9randum of understanding (MOU) with both of its collective bargaining units, the International Brotherho9d of Electrical Workers Local Union 1245 and the Organization of SMUD Employees.

SMUD participates in the California Public Employees' Retirement System (PE~lS), an agent multiple-employer public employee defined benefit pension plan. In 2015, SMUD implemented Governmental Accounting Standards Board (GASH) Statement of Governmental Accounting Standards (SGAS) No. 68 Accounting and Financial Reporting for Pensions-AnAmendment:ofGASB State!nent No. 27" (GASB No. 68). The primary objective of GASB No. 68 is to improve accounting and financial reporting by state and local governments for pensions.

Under GASB No. ,68, SMUD is required to report the net pension liability (i.e., the difference between the total pension liability and the pension plan's net position or market value of assets) in its Statement of Net Position.

This standard requires shorter amortization periods for recognition of non-investment gains and losses and actuanal assumption changes, as well as for recognition of investment gains and losses. GASB No. 68 also separates financial reporting from funding requirements for pension p*lans. Prior to this new guidanctf', a liability was recognized only to the extent that contr-ibutions made to the plan were less than the actuarially calculated contributions. At December 31, 2015 and 2014, the Net Pension Liability was $381.3 million and $326.7 million, respectively.

MANAGEMENT'S DISCUSSION AND ANALYSIS (Unaudited)

ASSETS AND DEFERRED OUTFLOWS OF RESOURCES Electric Utility Plant - net 2015 compared to 2014 As of December 31, 2015 SMUD has invested approximately $3,324.0 million in electric utility plant assets and construction work in progress (CWIP) after accumulated depreciation. Electric Utility Plant - net makes up about 56 percent of SMUD's Total Assets and Deferred Outflow of Resources, which is about four percent less than 2014. In 2015, SMUD capitalized approximately $123.0 million of additions to electric utility plant in the Consolidated Statements of Net Position. The additions were primarily due to distribution line work and purchases related to the replacement of bulk substations. These additions were offset

_by the retirement of a portion of SMUD's headquarters building in preparation for a major renovation, some fleet assets, and some hardware equipment.

2014 compared to -2013 As of December 31, 2014 SMUD has invested approximately $3,332.0 million in electric utility plant assets and CWIP after accumulated depreciation. Net Electric Utility Plant makes up about 60 percent of SMUD's Total Assets and Deferred Outflow of Resources, which is about one percent less than 2013. In 2014, SMUD capitalized approximately $199.0 million of additions to electric utility plant in the Consolidated Statements of Net Position. The additions were primarily due to distribution line work, hardware and software upgrades, and purchase of land for additional wind capacity and replacement of bulk substations.

These additions were offset by the retirement of the UARP recreational facilities and some photovoltaic assets.

The following charts show the breakdown of Electric Utility Plant - net by major plant category - Generation (Gen), Transmission (Trans), Distribution (Distr), and Other:

0 Other Restricted and Designated Assets 2015 compared to 2014 SMUD's restricted and designated assets are comprised of debt service reserves, nuclear decommissioning trust funds , rate stabilization reserves, and other third party agreements or Board actions. These assets decreased by $92.7 million during 2015 . The decrease was due to a transfer of$15.l million from the RSF (including the HRSF) as a result of lower precipitation and lower energy deliveries from WAPA, and a $16.1 million reduction in revenue bond and debt service reserves. In addition, there was a decrease of

$60.7 million in the other funds due to the release of various restricted funds of the component units, Sacramento Municipal Utility District Financing Authority (SFA) and Sacramento Power Authority (SPA), as a result of SFA's bond refunding and SPA's bond redemptions.

2014 compared to 2013 SMUD 's restricted and designated assets decreased by $37.4 million during 2014.

The decrease was partially due to a transfer of $36.2 million from the RSF (including the HRSF) as a result of lower precipitation and lower energy deliveries from WAPA. In addition, there was a decrease of $22.9 million in the nuclear decommissioning fund mainly due to payments made for the shipment of the low level radioactive waste to a permanent waste disposal facility. These decreases were offset by $11.0 million increase in the component units' overhaul and maintenance reserve and $13.7 million in the current portion of these assets.

LIABILITIES AND DEFERRED INFLOWS OF RESOURCES Long-Term Debt - net 2015 compared to 2014 SMUD's long-term debt includes the component units' debt and consists ofa variety of financial instruments, including interest rate swap agreements, subordinated electric revenue bonds and variable rate bonds. Proceeds from the bonds provide financing for various capital improvement projects, component unit capital projects, and the prepayment of a 20 year supply of natural gas.

In June 2015, SFA issued $193.3-million of2015 Series Cosumnes Project Revenue Refunding Bonds. Proceeds from the 2015 Series Bonds and $24.8 million of available funds wereused to refund $233 .2 million of the outstanding 2006 Series Bonds through a legal defeasance, and accordingly, the liability for the defeased bonds was removed from Long-Term Debt in the Statements of Net Position. The refunding resulted in the recognition of a deferred accounting loss of $4.4 million, which is being amortized over the life of the refunding issue, and a current period loss of $0.03 million which is included in Interest on Debt in the Statement of Revenues, Expenses, and Changes in Net Assets. As a result of the refunding, future aggregate debt service payments are reduced by $46.7 million and there is a total economic gain of $35 .5 million.

In January and July 2015, SPA redeemed $29 .9 million and the remaining $41.4 million, respectively, of the 2005 Series Bonds maturing July 2015 through July 2022, along with the accrued interest. The redemptions resulted in a current accounting loss of $0.2 million, which is included in Interest on Debt in the Statements of Revenues, Expenses, and Changes in Net Position.

2014 compared to 2013 In December 2014, SMUD redeemed $8.7 million of2004 Series T Bonds.

Sacramento Municipal Utility Distri<:t I 2015 Annual Report NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

/.

N'oTE 1. ORGANIZATION The Sacramento Municipal Utility District (SMUD) was formed and operates under the State of California Municipal Utility District Act (Act). The Act gives SMUD' the rights and powers to fix rates and charges for commodities or services it furnishes, and to incur indebtedness and issue bonds or other obligations.

As a community-owned utility, SMUD is not subject to regulation or oversight by the California Public Utilities Commission.

SMUD is responsible for the acquisition, generation, *transmission, and distribution of electric pm_ver to its service area, which includes most of Sacramento County and small adjoining portions of Placer and Yolo Counties.

The Board of Directors (Board) determines SMUD's rates.

SMUD is exempt from payment of federal and state income taxes and, under most circumstances, real and personal p~operty taxes. SMUD is not*exempt from real and personal property taxes on assets i~ holds outside of California.

In additiop, SMUD is responsible for the payment of a portion of the property taxes associated with its real property

.in California that lies outside of its service area.

-NOTE 2.

SUMMARY

OF SIGNIFICANT ACCOUNTiNG POLICIES Method of Accounting. SMUD's accounting records are maintained in accordance with Generally Accepted Accounting Principles for proprietary funds as prescribed by the Governmental Accounting Standards Board (GASB). SMUD's accounting records generally follow the Uniform System of Accounts for Public Utilities and Licensees prescribed by the Federnl Energy Regulatory Commission (FERC), except as it relates to the accounting for contributions of utility property in aid of construction. SMUD's *consolidated Financial Statements are reported using the economic resources 'measurement focus and the accrual basis of accounting.

Revenues are recorded when earned and expenses ar:e recorded when a liability is incurred, regardless of the timing of the related cash *flows. Electric revenues and costs that are directly related to the acquisition, generation, transmission, and distribution of electricity are reported a; operating revenues and expenses. All other revenues

. '

and expenses are reported as non-operating r:evenues and expenses.

-

Use of Estimates. The preparation of financial statements in con~ormity_ with accounting principles generally.

accepted in the Un~ted States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclo_sures of confingent*assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Actual results

• could differ from those estimates.

The Financial Reporting Entity. These Consolidated Financial Statements include SMUD and its component units. Although the component units are legally separate from SMUD, they are blended into and reported as part of SMUD because of the extent of their operational and financial relationships with SMUD. All significant inter-component transactions have been eliminated in consolidation.

I Component Units. The component units include the Central Valley Financing Authority (CVFA), tl).e Sacramento Cogeneration Authority (SCA), the Sacramento Municipal Utility District Financing Authority (SFA), the Sacramento power Authority (SPA), and the Northern California Gas Authority No. 1 (NCGA). The primary .

purpose of CVFA, SCA, SFA and SPA is to own and operate electric utility plants that supply power to SMUD.

The primary purpos'e ofN~GA is to_ prepay for natural_ gas and to sell the natural gas to SMUD. SMUD's Board comprises the Commissions that govern these entities (see Note 6).

Sacramento Municipal Utility District l,2Q15 Annual Report NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Plant in Service. Capital assets are generally defined by SMUD as tangible assets with an initial, individual cost of more than three thousand dollars and an estimated useful life in excess of two years. The cost of additions to Plant in Service and replacement property units is capitalized. Repair and m_aintenance costs are charged to expense when incurred. When SMUD retires portions of its Utility Plant, retirements are recorded against Accumulated Depreciation and the retired portion of Utility Plant is removed from Plant in Service. The costs of removal and the related salvage value, if any, are charged or credited as appropriate to Accumulated Depreciation. SMUD generally computes ~epreciation on Plant in Service on a straight-line, service-life basis. The consolidated average annual composite depreciation rates for 2015 and 2014 were 3.5 percent.'Depreciation is calculated using the following

. estimated liv.es: * . . .

/

Generation 4 to 80 years Transmission and Distribution .5 to 50 years Gas Pipeline *5 to 90 years General 5 to 60 years

. Investments . in Joint Power Agency. (JPA).. SMUD;s in~estment in the Transmission Agency of .Northern California (TANC) is accounted for under the equity mt<thod of accounting *and is reported as a component of Plant in Service. SMUD's share of the TANC debt service costs and operations and maintenance expense, inclusive of

• depreciation, is included in Transmission and Distribution expense in the ~onsolidated*Statements of Revenues, Expenses and Changes in Net Position.

SMUD's investment in Balancing AuthoritY of Northern California (BANC) is accounted for under the equity method of accounting. SMUD's share of the BANC operations and maintenance expense is included in Transmission and Distribution expen,se in the Consolidated Statements of Revenues, Expenses and Changes in Net Position.

Investment in Gas Properties. SMUD has an approximate 21 percent non-operating ownership interest in the Rosa Unit gas properties in New Mexico of which, SMUD's portion of the extracted gas is tran.sported for use in its component unit natural gas-fired pO\yer plants (see Note 6). SMUD uses -the successful efforts method of accounting for its investment in gas producing properties. Costs to acquire mineral interests in gas properties, to drill and equip exploratory wells that find proved reserv~s, and to drill anci equip development wells are capit!llized as a component of Plant in Service on the Consolidated Statements of Net Position. Costs to drill exploratory wells that do not find proved reserves, geological and geophysical costs, and costs of carrying and retaining unproved properties are expensed. SMUD has purchased proven reserves and has not participated iri exploratory drilling. .

Capitalized costs of producing gas pr~perties; after considering estimated residual_ salvage values, are depleted by the unit-of-production method based on the estimated fufure production of the proved developed producing wells.

SMUD's investment in gas properties is reported as a component of Plant ii: Service Restricted and Designated Assets. Cash, cash equivalents, and investments, which are restricted under terms of certain agreements for payments to third parties or Board actions limiting the use of such funds, are included as restricted assets. When SMUD restricts funds for a specific purpose, and both restricted and umestricted resources are available for use, it is SMUD's policy to use restricted resources first, then umestricted resources as they are needed.

Restricted Bond Funds. SMUD's Indenture Agreements (Indenture) requires the maintenance of minimum levels ofreserves for debt service on the 1997 Series K Bonds and the 2003 Series R Bonds. In 201\ the 2003 Series R Bonds were paid off and only the res.erve for debt *service for the 1997 Series K Bonds existed at December 31, 2015:

Sacramento Municipal Utility District I 2015 Annual Report "NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Nuclear Decommissioning ~ust Fund. SMUD made annual contril:lutio~s to its Nuclear Decommissioning Trust Fund (Trust Fund) through 2008 to _cover the cost of its primary decommissioning activities associated with the Rancho Seco facility. Primary decommissioning excludes activities associated with the spent fuel storage facility after 2008 and most non-radiologi'cal decommissioning tasks. SMUD determined early in 2008 that there were

'enough funds in th_e trust to complete the radiological decommissioning of the Rancho Seco nuclear plant site, and stopped contributing to the Trust Fund*(see Note 12). Interest earnings on the Trust Fund assets are recorded as Interest Income and are accumulated in the Trust Fund.

Accrued Decommissioning. SMUD accrues decommissioning costs related to Utility Plant when an obligation to decommission facilities is legally required. Adjustments are made to such liabilities based on estimates by SMUD staff in accordance with FASB ASC 410, Assei Retirement and Environmental Obligations_ (FASB ASC 410). For active plants, such costs are included in the Utility Plant's cost and included as a component of Operating Expense over the Utility Plant's life. Expenditures for decommissioning activities are recorded as reductions to Accrued Decommissioning liability. Changes in the Rancho Seco decommissioning liability estimates arising from inflation, annual accretion,. and other ~hanges to the cost assumptions *are recorded to Accrued Decommissioning with a corresponding adjustment to the related regulatory deferral. The current portion of the Accrued Decommissioning liability represents SMUD's estimate of actual _expenditures in the next year, as set forth in the annual budget.

SMUD has identified potential retirement obligations related to certain generation, distribution and transmission

- .

facilities. SMUD's non-perpetual leased land rights generally are renewed continuously because SMUD i_ntends to utilize these facilities indefinitely. Since the timing and extent of any potential asset retirements are unknown, the fair value of any obligations associated with these facilities cannot be reasonably estimated. Accordingly, a liability .

has not been recorded.

• At December 31, 2015 and 2014, SMUD's Accrued Decommissiop.ing balance in the Consolidated Statements of Net Position relating to Rancho Seco.was $150.4 million and $152.1 million, respectively (see N~te 12). The Accrued Decommissioning balanc_e in the Consolidated Statements of Net Position relating to other electricity generation and gas production facilities totaled $10.8 million and $10.1 million as of December 31, 2015 and*

2014, respectively.

Cash and Cash Equivalents. Cash and cash equivalents *include all debt instruments purcha_sed with an original maturity of 90 days or less, ap investments in the Local Agency Investment Fund (LAIF), and money market mutual funds. LAIF has an equity interest in the State of California (State) Pooled Money Investment Account (PMIA). PMIA funds are on depositwith the State's Centralized Treasury System and are manage.cl in compliance with the California Government Code accord!ng to a statement of investment policy which sets forth permitted investment vehicles, liquidity parameters, and maximum maturity of investments. SMUD's deposits with LAIF comprise cash representing demand deposits up to $50.0'million maximum.and c.ash equivalents representing amounts which may be withdrawn once per month after a thirty-day period. The debt instruments and money market mutual funds are reported a~ amortized cost, which approximates.fair value, and the_ LAIF is reported at the value of its pool shares.

Investments. SMUD's investments held for more than one year are reported at fair value. Realized and unrealized

. gains and losses ar~ included in Other Income - Net in the Consolidated Statements of Revenues, Expenses and Changes in Net Position. Premiums and discounts on zero coupon bonds are amortized using the effective interest method. Premiums *and discounts on other securities are amortized using the straight-line method, which approximates the effective interest method.

SMUD ANNUAL REPORT 201s I Forward

Sacramento Municipal Utility District I 2015 Annual Report NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Electric Operating Revenues. Electric revenues are billed on the basis of monthly cycle bills and are r~corded as

. ~

revenue when the electricity is delivered. SMUD record~ an estimate for unbilled revenues earned from the dates _its

' retail *customers were last billed to the end of the month. At December 31, 2015 and 2014, unbilled revenues were

$72.5 million and $69.1 million, respectively.

Purchased Power Expenses. A portion of SMUD's power needs are provided through power purchase agreements .

. Expenses from such agreements, along with associated transmission costs paid to other utilities, are. charged to Purchased Power expense on the Consolidated Statements of Revenues,- Expenses and Changes in Net Position in the period the power is receiv~d. The costs, 6r credits, associated with enerzy s_wap agreements (gas and electricity) or other arrangements that affect the *net cost of Purchased Power are recognized in the period in which 'the underlying power delivery occurs. Contract termination payments and adjustments to prior billings are included in Purchased Power expense once the payments or adjustmen~s can be reasonably estimated.

Advanced Capacity Payments. Some lon_g-term agreements to purchase energy or cap~city from other providers call for up-front payment. Such costs are generally recorded as an asset and amortized over the length

_ of the contract.

Credi_t and Market Risk. SMUD enters into forward purchase* and sales commitments for physical delivery,of gas and electricity with utilities and power marketers. SMUD is exposed to credit risk related to nonperformance by its wholesale ~ounterparties under the terms of these contractual agreements. In order to_ limjt the risk of counterparty default, SMUD has a wholesale counterparty risk policy which includes using the credit agency.

ratings of SMUJ?'s counterparties and other credit services, credit enhancements for counterparties that do not meet an acceptable risk level, and the use of standardized agreements that allo>y for the nettil).g of positive and negative exposure~ associated with a single counterparty. SMUD is also subject to similar requirements for many of its gas and power purchase agreements. SMUD uses a combination of cash and securities to satisfy its collateral requirements to counterparties. SMUD.'s component unit, NCGA, entered into a-guaranteed investment contract and is exposed to credit risk related to nonperformance by its. investment provider. The investment provider provides collateral iftheir credit ratings fall below agreed upon levels. At Dec~mber 31, 2015 and 2014, respectiyely, SMUD held-$4.4 million and $0.2 million on deposit by counterparties and ari investment provider. The amo:unt issecorded as unrestricted cash and current restricted cash with an associated ~urrent liability. At December 31, 2015 and 2014" SMUD posted cash collateral of $48.7 million and $4.0 million, respectively, with counterparties.

Accounts Receivable and Allowance for Doubtful Accounts. Accounts Receivable is recorded at the invoiced amount and does not bear* interest, except for accounts related to energy efficiency loans. SMUD reco~nizes an estimate of uncollectible accounts for its receivables related to electric service, energy efficiency loans, and other non-electric billings, based upon its historical experience with collections and current energy market conditions.

For large wholesale receivable balances, SMUD determines its bad debt reserves based on the specific credit issues for each account. SMUD records bad debts for its estimated uncollectible accounts related to electric service as a ..

reduction to the related operating revenues in ~he Consolidated .Statements of Revenues, Expenses and Changes in Net Position. SMUD records bad debts for its estimated uricollectible accounts related to .energy efficiency loans and other non-electrjc billings in Administrative, General and Customer expense in the Consolidated Statements of Revenues, Expenses and Changes in Net Position._

As a regulated entity, SMUD's financial statements are prepared in accordance with GASB Statement No. 62 (GASB No. 62), "Codification ofAccounting and financial Reporting Guidance, Contained in Pre-November 30, 1989 FASB and A/CPA I;'ronouncements," which requires that the effects of the rate-making process be recorded in the financial statements. Accordingly, certain expenses and credits, normally reflected in Change in Net Position *

~as incurred, are recognized when included in rates and recovered from, or refunded to, customers. SMUD records *

• various regulatory assets and credits to reflect rate-making actions of the Board (see Note_ 8).

Materials and Supplies. Materials and supplies are stated at average cost, which approximates the first-in, first-oi.{t method. /

Compensated Absences. SMUD accrues vacation leave and compensatory time when employees earn the rights to the benefits. SMUD does_ not record sick leave as a liability until it is taken by the employee, since there are no cash payments for sick leave made "'.Nhen employees terminate or retire. At December 31, 2015 and 2014, the total estimated liability for vacation and other compensated absences was $23.9 million and $23.0 million, respectively.

. Public Good. Public Good expenses consist of non-capital _expenditures for energy efficiency programs, low income subsidies, renewable energy resources and technologies, and research and *development.

Gains/Losses on Bond Refundings. Gains and losses resulting from bond refundings are included as a component of Deferred Inflows of Resources or Deferred Outflows of.Resources on the Consolidated Statements of Net Position and amortized .as a component of Interest on Debt in the Consolidated Statements of Revenues, Expenses and Changes in Net Position over the shorter of the life of the refunded debt or the new debt using the effective interest method.

Gains/Losses on Bond D.efeasances or Extinguishments. Gains and losses resulting from bond defeasances or extinguishments that were not financed with the issuance of new debt are included as a component of Interest on Debt in the Consolidated Statements of Revenues, Expenses and Changes in Net Position.

Sacramento Municipal Uttlity District I 2015 Annual Report NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Allowance*for*Funds Used During Construction (AFUDC). SMUD capitalizes, 'as.an additional cost of Constru~tion Work In Progress (CWIP), AFUDC, which represents _the cost of borrowed funds used for such purposes. The amount capitalized is determined by a formula prescribed by FERC. The AFUDC rate for 2015 and 2014 was 2.8 percent and 3.3 percent, of eligible CWIP,.respectively.

Derivative Financial Instruments. SMUD records 'derivative financial instruments (interest rate swap and gas price swap agreements, certai~ wholesale sales agreements, certain power purchase agreements anti option agreements) at fair value on its Consolidated Statements of Net Position. SMUD does not enter into agreements for speculative purposes. Fair market value is estimated by comparing contract prices to forward market prices quoted by third party market I?articipants and/or provided in relevant industry publications. SMUD is exposed to risk of nonperformance if the couriterparties default or if the swap agreements are terminated. SMUD reports.

deriyative financial instruments with remaining'_maturities of one year or less and the portion of long-term con~acts with scheduled transactions over the next twelve months as current on the Consolidated Statements of Net .Position (see Note 9).

Interest Rate Swap Agr~ements . .SMUD enters into interest rate swap agreements to modify the effective interest rates on outstanding debt (see Notes 9 and 10).

Gas and Electricity Price Swap and Option Agreements. SMUD uses forward contracts to hedge the impact of market.volatility on gas commodity prices for it~ gas-fueled power plants and for energy prices on purchased power for SMUD's retail load (see Note 9).

• Solano Wind Sale. SMUD entered 1nto an agreement to sell the Solano Wind Phase 3 plant in December 2011 with a corresponding Power Purchase Agreement for all the output of the plant. In April 2012, under the terms of the Construction Management. Agreement, SMUD, on behalf of the purchaser, completed construction of the plant, with.the revenue recognition from the transaction, which was accounted for as a financing agreement, to occur over the life of the contracts. Pursuanfto the Facil~ty Administration Agreement, SMUD will perform services at the facility under the direction and for the benefit of the purchaser. Pursuant to the ground and property lease, SMUD is leasing the site to the purchaser for a term of twenty years with an option to extend for five additional years.

The sale proceeds have been recorded as Deferred Inflows of Resources on the Consolidated Statements of Net Position and will be amortized as Purchased Power Expense' on the Consolidated Statement of Revenues, Expenses, and Changes in Net Position over the life of the agreement. Sale proceeds in the amount of $63 .1 million were received in 2013. The prtjpayment for purchased power over the life of the contract has been recorded as Prepaid P_ower and Capacity on the Consolidated Statements of Net Position and will be amortized as Purchased Power Expense on the Consolidated Statement of Revenues, Expenses, and Changes in Net Position .over the life of the agreement (see Note 16 for language about the Power Purchase Agreement).

• Precipitation Hedge Agreements. SMUD enters into non-exchange traded precipitation hedge agreements to hedge the cost of replacement power caused by low precipitation years (Precipitation Agreements). SMUD records the intrinsic value oqhe Precipitation Agreements on the Co.nsolidated Stat~ments ofNet Position. Settlement of the Precipitation Agreements is not performed until the end of the period covered (water year ended September 30). '

The intrinsic .value of a Precipitation Agreement is the difference between the expected results from a monthly allocation of.the cumulative rainfall amounts, in an average rainfall year, and the actual rainfall during the same period.

_Sacramento Municipal Utility District I 2015 Annual Report

• ) NQTES TO CONSOLIDATED FINANCIAL STATEMENTS Insurance-Programs. SMUD records liabilities for unpaid claims at their present value when they are probable in occurrence and the amount can be reasonably estimated. SMUD records a liability for up.paid claims associated

/ .

with general, auto, workers' compensation, and short-term and long-term disability based upon es1imates derived by SMUD's claims administrator or SMUD staff. The liability comprises the present value of the claims outstanding, and j.ncludes an amount for claim events incurred but not reported based _upon SMUD's experience* (see Note 15).

Pollution Remediation. St~tem~nt of Governmental Accounting Standards (SGAS) No. 49, "Acco~nting and

• Financial Reporting for Po{lution Remediation Obligations," requires that a liability be recognized for expected outlays.for remediating existing pollution when certain triggering events occur. In.2009, SMUD*identified a pollution remediation qhligation at its North City Substatl.on. This substation was built on a former landfill, and the sitt: requires remediation. In 2015, SMUD identified and recorded a pollution remediation obligation at its Headquarters building that it will be renovating. In addition, SMUD recor~ed a pollution remedil:}tion obligation at the Former Community Linen Rental Services (see Note 17). At December 31; 2015 and 2014, the total pollution remediation liability is $19.7 million and $12.2 'million, respectively. Costs were estimated using the expected cash fl9w technique prescribed under GASB.

Hydro License. SMUD,owns and operates the Upper American River Hydroelectric Project (UARP). The original Iice'nse to construct and operate the UARP was issued in '19S7 by FERC. In 2014, SMUD received a new hydro license for a term of 50 years, effective July), 2014. A; part of the hydro licensing process, SMUD entered into four contracts with government agencies whereby SMUD makes annual payments to them for various services for th~ t\!rm of the license. At December 31, 2015 and 2014, tlle liabili_ty for these contract payments is $55.0 million and $56.1 million, respectively (see Note 16).

Assembly Bill 32. California Assembly Bill 32 (AB-32) is an effort by the State of California to set a 2020 greenhouse gas emissions reduction goal into law. The goal is to reach a sta~ewide emission limit of 427 million metric tons of carboffdioxide equivalent of greenhouse gases (GHG). Central to this initiative is the implementation of a cap and trade program, which covers major sources of GHG emissions in the State including power plants.

The cap and trade program includes an enforceable emissions cap that will decline over time. The State will distribute allowances, which are lradable permits, equal to the emissions allowed under the cap. Sources under the cap will need to surrender allowances and offsets equal to their emissions at the end of each compliance petiod.

r SMUD is subject to AB-32. SMUD participated in the program auctions ill 2014 and 20~5. In a normal water year, SMUD expects its free allocation ofallowances from the Air Resources Board will cover its compliance costs associated with electricity delivered to its retail customers*. SMUD expects to recover compliance costs associated with wholesale power sales costs through its wholesale power sales revenues. SMUD is monitoring legislation and

• proposed programs that would impactAB-32 (see Note 8).

Net Pension Liability (NPL). SMUD implemented SGAS No. 68 Accounting and Financial Reporting for Pensions -An Amendment ofGASB Statement No. 27" (GASB No. 68) in-2015 (see Note 3). Und.er GASB N-0. 68, the net pension liability is the difference between the actuarial present value of projected pension benefit payments attributable to employees' past service and the Plan's fiduciary net position. At December 31, 2015 and

.2014, the NPL was $381.3 million and $326.7 million, respectively.

Sacramento Municipal Utility District I 2015 Annual Report NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Net Position. SMUD class}fies its net position into three components as follows:

• Net investment in capital assets - This component* of net position consists of capital assets, net qf Accumulated Depreciation, reduced by the outstanding debt balances, net 6f unl:!mortized debt expenses. Deferrt?d inflows and outflows of resources that are attributable to the acquisition, construction or improvement of those assets or related

• debt are also included.

• Restricted - This component of net position consists of assets with constraints placed on their use, either externally or ~ternally. constraints include those imposed by debt indentures cexcluding amounts considered in n_et capital, above), grants or laws and regulations of other governments, or by law through constitutional provisions or enabling legislation or by the Board. These restricted assets are reduced by liabilities and deferred inflows of resources related to those assets.

• Unrestricted -,This component of net position consists of net amount ~f the assets, deferred outflows of resources, liabilities, and deferred inflows of resources that do not meet the definition of"Net investment in capital assets" or "Restricted."

Contributions in Aid of Construction (CIAC). SMUD records CIAC from customer contributions, primarily relating to expansions to SMUD's distribution facilities, as Other Income - Net in the Consolidated Statements of Revenues, Expenses and Changes l.n Net.Position. Contributions of capital are valued at estimated market cost.

-For rate-making purposes, the Board does not recognize such revenues when-received; rather, CIAC is included J.n revenues as such costs ~re ainortized over the estimated useful lives of the related distribution facilities.

• Revenues -and Expenses. SMUD distinguishes operating revenues and expenses from non-operatiag items.

Ope~ating revenues and expenses generally result from pro\'.iding seryices and producing and delivering goods in connection with SMUD's principal ongoing operations. The principal operating revenues of SMUD a.re charges to customers for sales a,nd services. Operating expenses include the cost of sales and services, administrative

, expenses, and depreciation on cap_ital assets. All revenues and expenses ~ot meeting this definition are reported as non-operating revenues and expenses.

Grants. SMUD receives grant proceeds from fed~ral an.d state assisted programs for its advanced and renewable technologies, electric vehicle, and em<rgy efficiency programs. SMUD *also periqdically receives grant proceeds*

from federal or state* assistance programs as pai:tial reimbursements for costs it has incurred as a result of storm damages. When applicable, these programs may be subject to financial and compliance audits pursuant to regulatory requirements. SMUD considers the possibility of any matedal disallowances to be remote. During 2015, SMUD recorded $3 .0 million of grant proceeds and recognized $2.5 mill1on as a compon_ent of Other 1ncome - Net, in the Consolidated Statements of Revenues, Expe-;;_ses and Changes in Net .Rosi~ion, and

$0.5 million as a Regulatory Credit (see Note 8). During 2014, SMUD recorded $3.2 million of grant proceeds and recognized $4.8 million as a c_g.rnponent of Other Income - Net, in the Consolidated Statements of Revenues, Expenses and Changes in Net Position, $1.6 milllon as a Regulatory Credit (see Note 8), and a $3.2 million decrease in unearned revenue as a component of Customer Deposits and Other on the Consolidated Statements

)

of Net Position.

Sacramento Municipal Utility District I 2015 Annual Report NOTES TO CONSOLIDATED FINANCIAL STATEMENTS In 2010, SMUD issued taxable Build America Bonds. SMUD receives an interest subsidy from the federal govertnfient equal-to 35 percent of the interest paid (see Note 10). SMUD received reduced subsidy payments in 2015 and 2014 due to budget sequestration by the federal government. SMUD recognized $9.'l million in revenues in 2015 and also in 2014 for its Build America Bonds,- as a component- of Other Income - Net, in the .

Consqlidated Statements of Revenues, Expenses and Changes in Net Position.

Customer Sales and Excise Taxes. SMUD is required by various governmental authorities, including states and municipalities, to collect and remit taxes on certain customer sales. Such taxes are p:esented on a net basis and excluded from revenues and expenses in the Consolidated Statements of Revenues, Expenses and Changes in Net Position.

• Rancho* Seco Litigation. In June 1983, SMUD and the U.S. Depifrtment of Energy (DOE) entered into a contract whereby the DOE would build a repository for the acceptance and disposal of SMUD's spent nuclear fuel (SNF) and/or high-level radioactive waste (HLW). SMUD paid the DOE a total of approximately $40.0 million in fees under the contract, thus satisfying its obligation of performance under the contract. DOE did not build a repository and therefore breached . its obligation under the contract to commence acceptance of SNF and. HLW by January 31, 1998. As a result, SMU:D incurred costs to design, license, and fabricate its own: on-site storage facility for the long term dry storage of its spent fuel at Rancho Seco. SMUD filed a suit against the DOE in 1998-which covered costs incurred from 1992 through 2003 and filed another suit in 2009 which covered costs incurred from 2004 through 2009. In September 2014 and February-2015, SMUD received awards for $53.l million and $22.5 million from the U. S. Court of Claims, respectively, which were recorded as Other Income - Net in the ConsO"lidated.Statements of Revenues, Expenses and Chang~s in Net Position. In June 2015, SMUD filed a s.uit against DOE which covered the costs incurred from 2010 through at least June 2015.

Subsequent Events. Subsequent events for SMUD have been evaluated through February 19, 2016, which is the date that the financial statements were available to be issued.

Reclassificl!tions. Certain amounts in the _20 i 4 Consolidated Financial Statements have been reclassified in order

/

to conform to the 2015 presentation.

Recent Accounting Pr~nouncements. In February 2015, GASB issued ~GAS.No. 72, "Fair Value Measurement andApplication"_ (GASB No. 72). GASB No. 72 addresses *accounting and financial reporting iss~es related to fair value measurements. This statement requires investments to be measured at fair value, which is described as an exit price. This statement requires valuation techniques that are appropriate in the circumstances and for which

-sufficient data are available to be us~d. to measure fair value. The valuation techniques should be consistent with one or more of the following approaches: the market approach, the cost approach, or the income approach. This statement establishes a hierarchy of inputs to the valuation techniques used to measure fair value. The hierarchy has th_ree levels. Level 1 inputs are quoted prices (unadjusted) in, active markets for identical assets or liabilities:

Level 2 inputs are inputs, other than quoted prices, include~ within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 inputs. are unobservable inputs, such as management ass~mptions.

A fair value takes into account the highest and best use for a nonfinancial asset. This stateme.nt requires disclosures to be made a~out fair value measurements,' the level of fair value hierarchy, and valuation te~hniques. GASB No. 72 is effective for SMUD in 2016. SMUD is currently assessing the financial statement impact _of adopting th~s statement,' but does not believe that its impact will be material.

SMUD ANNUAL REPORT 2015 I Forward I

Sacramento Municipal Utility District I 2015 Annual Report NOTES TO CONSOLIDATED- FINANCIAL STATEMENTS In June 2015, GASB issued SGAS No. 75, "Accounting and Finandal Reporting for Postemployment Benefits Other Than Pensions" (GASB No. 75). The primary objective of GASB No. 75 is to improve accounting and financial reporting by state and local go:vernments for postemployment benefits other than pensions (other postemployment benefits or OPEB). 'Fhis statement replaces the requirements of SGAS No.' 45 "Accounting and Financial Reporting by Employers for Post Employment,Be,nefits Other Than Pensions," as amended, and SGAS No. 57 "OPEB Measurements by Agent Employers aJ:ld Agent Multiple-Employer Plans." This statement establishes standards for measuring and recognizing liabilities, deferred outflows and deferred inflows of resources, and exp~nses. For defined benefit OPEB, GASB No. 75 identifies the methods-and assumptions that are required_

to be used to 'project benefit payments, discount projected benefit paym~nts to their actuarial present value, and attribute that present value to periods of employee service. Note disclosure and required supplementary information requirements about defined bei:iefit OPEB also are addressed. In addition, this statement details the recognition and disclosure requirements for employers with payables to defined- benefit OPEB plans that are administered

. through trusts that meet the specified criteria. This statement is effective for SMUD in 2018. SMUD is currently -

assessing the financial statement impact of adopting this statement.

In June 2015, GASB issued SGAS No. 76, "The Hierarchy ofGenetallyAcceptedAccounting Principlesfdr State and Local Governments" (GASB No. 76). GASB No. 76 established_ the hierarchy of GAAP for state and local governments. This statement supersedes SGAS No. 55, "The Hierarchy of Generally Accepted Accounting Principles for State and Local Governments." The GAAP hierarchy sets forth what constitutes GAAP for all state and local governmental entities. It establishes the order of priority of pronouncements and other sources of accounting and financial reporting guidance that a governmental entity should apply. Category A is comprised of GASB statem,e~ts. Category B includes GASB Technical Bulletins, G~SB Implementation Guides, and literature of the AICPA cleared by the GASB. GASB No. 76 is effective for SMUD in 2016. SMUD is ClJrrently assessing the financial statement impact of adopting this statement, but does not believe that its impact will be material.

NOTE'3.-ACCOUNTING CHANGE In.June 2012, GASE.issued GASB No. 68. The primary objective ofGASB No. 68 is to improve accounting and financial reporting by state and local governments for pensions. This statement establishes standards for measuring and recognizing liabilities, deferred outflows and deferred inflows of res9urces, and expenses. For defined benefit pensions, this statement identifies the methods and assumptions that' should be used to project benefit P.ayments, discount projeded benefit payments to their actuarial present valUe, and attribute that present value to periods of employee service. Note disclosure and required supplementary information requirements*

about pensions also are addressed.

This statement is effective for SMUD in 2015. The implementation impacted the Consolidated Statements of Net Position when the net pension liability, the corresponding deferred outflows.and deferred inflows of resources,

,and a reduction in prepaid pension were recorded. SMUD elected to follow accounting for regulated operatio!ls tinder GASB No. 62 and recorded a regulatory asset as of December 31, 2014, in the _amount of $425.7 million to account for the net effect of required prior period adjustments to recognize the net pension liability. Amortization

• of the regulat9ry asset will begin in 2018. The implementation also imp~cted the Consolidated Statements of Revenues, Expenses and Changes in Net Position as a reduction in pension expense was also recorded. SMUD restated the December 31; 2014 Consolidated Statement of Net Position and Consolidated Statement of Revenues, Expenses and Changes in Net Position to reflect the changes for comparative purposes. SMUD has updated Note 13 Pension Plans to include the requirements of GASB No. 68.

Sacramento Municipal Utility District. I 2015 Annual Report NOTES TO CONSOLIDATED FINANCIAL STATEMENTS In November 2013, GASB issued SGAS N_o. 71, "Pensi_on Transition for Contributions Made Subsequent to the Measurement Date, an amendment ofGASB Statement No. 68" (GASB No:71). GASB No. 71 addresses an issue regarding application of the transition provisions o:i' GASB No. 68. The issue relates to amounts associated with contributions, if f!.ny, made by .a state or local. government employer or nonemployer contributing entity to a defined. benefit pension plan after the measurement date of the government's beginning net pension liability.

GASB No. 71 amends paragraph 137 of GASB No. 68 to require that, at trap.sition, a government recognize a

_beginning deferred outflow of resources for its pension contributions, if any, made subsequent to the measurement

• date of the beginning net pension liability. This statement is effective for SMUD in 2015 and SMUD has applied it simultaneous!y with the implementation of GASJ3 No. 68.

SMUD has restated amounts of the affected balances within the financial statements for the period ended December 31,-2014, as follows:

' '

Cash Equivalents and Investments. SMUD's investment policy is governed by the California State and Municipal Codes and its Indenture, which allow SMUD's investments to include: obligations which are unconditionally guaranteed by the United States (U.S.) Government or its agencies or instrumentalitie~; direct and general obligations of the State.or any local agency within the State; bankers' acceptances; commercial paper; certificates of deposit; r~purchase agreements; corporate notes; and taxable government and tax-exempt ~oney market .

portfolios. SMUD's investment policy includes restrictions for.investments relating to maximum amounts invested as a percentage of total portfolio and with a single issuer, maximum maturities, and minimum credit ratings.

1 Credit Risk. This is the risk that an issuer 'of an investment will not fulfill its obligation to the holder of the investment. To mitigate this risk, SMUD limits investments to those.rated, at a minimum, "A-I-" or equivalent for commercial paper arid "A" or equivalent for medium-terin corporate notes by a nationally recognized rating agency.

Custodial, Credit Risk. This is the risk that, in the event of the failure of a depository financial institution or counterparty to a transaction, SMUD's deposits may not be returned or SMUD will not be able to recover, the value of its deposits, investments or collateral securities that are in the po~session of another party. SMUD does not have a deposit policy for custodial credit risk.

As of December 31, 2015 and 2014, $23 .2 million and $9. 7 million in *deposits were uninsured, respectively.

The bank balance is also, per a depository pledge agreement between SMUD and SMUD's bank, collateralized at

. 117 percent a'nd 132 percent of the coll{\ctive funds on deposit (increased by the amount of accrued but uncredited interest, reduced by deposits covered by FDIC) at December 31, 2015 and 2014, respectively. At December 31, 2015 and 2014, SMUD had money market deposit accounts and .mutual funds of $1 O? .3 million ~nd $161.1 million which were uninsured, respectively. SMUD's investments and money market mutual funds are held*in SMUI?'s name.

Concentration of Credit Risk. This is the risk of loss attributed to the magnitude of an entity's investment in a single issuer. SMUD places no limit on the amounts invested in any one issuer for repurchase agreements and federal agency securities. The following are the concentrations of risk greater than five percent in either year:

Sacramento Municipal Utility District I 2015 Annual Report NOTES TO CONSOLIDATED FINANCIAL STATEMENTS NOTE s. REGULATORY DEFERRALS .

The Board has taken various regulatory actions that result in differences between the recognition of revenues and expenses for rate-making purposes and their treatment under generally accepte~ acyounting principles for non-regulated entities. These actions result in regulatory assets and li~bilities, which.are summarized in the tables below.

Changes to these balances, and their inclusion in rates, occur only at the direction of the Board.

Regulatory Assets (Costs)

'*

Decommissioning. SMUD's regulatory-asset relating to the ~funded portion of its decommissioning liability is being collected through interest earnings .on the Trust Fund. Nuclear fuel storage costs and non-radiological decommissioning costs have been collected in rates since 2009.

Derivative Financial Instruments. SMUD's regulatory costs and/or credits relating to Investment Derivative Instruments are intended to .defer the net difference between the fair value of derivative instruments* ~.d their cost basis, if an)'.: Investment Derivative Instruments are reflected in rates at contract cost and as such, the balance is charged or credited into rates as the related asset or liability is util~zed (see Note 9).

Senate Bill 1. SMUD implemented a per kilowatt hour solar surcharge, effective January 1, 2008 in order to fund investments in solar required by Senate Bill 1 (SB-i). The diffyrence between ~he surcharge revenues received and the funds spent on solar initiatives will be recognized or deferred into future years. SMUD has spent more than it has collected in SB-1 revenues and has recorded a regulatory asset.

Debt Issuance Costs. SMUD established a regulatory asset for costs incurred in connection with the issuance of*

debt obligations, principally underwriter fees. and legal cost~. The regulatory asset will be collected in rates over the life of the bonds. Debt issuance costs after December 31, 2013 are expensed. -

Pension. SMUD establl.shed a regulatory asset for pension costs related to the implementation of GASE No. 68 which requires SMUD to record a net pension liability. Amortization of the regulatory asset will begin in 2018 as part of the next rate case.*

SMUD's total* regulatory costs for future recovery are presented b_elow:

Sacramento.MuniCipal Utility District I 2015 A.nnual Report NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

~egulatory Credits CIAC. In 2015 and 2014 SMUD added CIAC totaling $16.9 million and $20.2 million, respectively, to Regulatory Credits in the Consolidated Statements ofNet Position and,recorded $10.9 million and $10.4 million of amortization, respectively, to Other Income - Net in the Consolidated Statements of Revenues, Expenses and Changes in Net Position. SMUD's regulatory credit relating to CIAC is intended to offset the revenue and expense associated with this accounting treatment. Thus, this regulatory credit is being amortized into rates over the depreciable lives of the related assets in order to offset the earnings effect of these non-exchange transactions.

Rate Stabilization. SMUD's regulatory credit relating to Rate Stabilization _is intended to defer the need for future rate inci:eases when costs exceed existing rates. At the difection of the Board, amounts*may be either transferred into this fund (which reduces revenues), or amounts are transferred out of this fund (which increases revenues).

The Board authorizes Rate Stabilization Fund (RSF) transfers on an event driven basis. In 2015, $12.0 million was transferred from the RSF to revenue as a result of lower than budgeted energy deliveries from Western Area Power Administration (Western). -

Hydro Rate Stabilization. The Hydro Rate Stabilization Fund (HRSE) was established through the Hydro

'Generation Adjustment (HGA) mechanism, which helps manage volatility in energy costs. The HGA mechanism applies a formula based on precipitation and wholesale electricity prices to calculate needed withdrawals from or

/deposits to the HRSF. The maxim~m balance of the HRSF is 5 percent of the budgeted retail revenue and the

,maximum annual transfer in or out of the HRSF is 4'percent of budgeted retail revenue. If the HRSF is depleted SMUD will apply a hydro rate surcharg~ to customers' bills ~p to 4 percent. When the HRSF is fully replenished, a wet year can trigger a hydro rebate or credit on the customers' bills. In 2015, $3.l million was transferred from the HRSF to revenue as a result of below. average precipitation. In April 2015, the HRSF was depleted and a hydro rate surcharge was implemented.

Assembly Bill 32. SMUD participated in the carbon allowance auctions under AB-32, the Global Warming_

.Solutions Act (see Note 2). In 2012, the Board authorized the deferral of AB-32 auction proceeds to match the revenue recognition with. the related expenses. The differenc'e between the auction proceeds received and the funds spent on AB-32 programs are deferred into future years. At December 31, 2015, all proceeds have been spent.

' . ,

Grant Revenues. In- 2009, SMUD was awarded several large gr.ants under the ARRA, which provided large amounts of reim,)Jurs~ments for capital expenditures. IJ.?. 2010, the Board authorized the deferral of grant income for capital expenditures as regulatory liabilities. Thus, this regulatory credit will be deferred to match the depreciable, lives of the related capit~l assets in order to offset the earnings* effect of these non-exchange transactions.

TANC Operations Costs. SMUD's regulatory asset relating to deferred TANC costs comprises tlie difference between its cash payments made to TANC and its share ofTANC's accrual-based costs of operations. This regulatory asset is being collected in rates over the life ofTANC's assets during the-period that cash payments to TANC exceed TANC's accrual-based costs. SMUD's cash payments to TANC exceeded TANC's accrual-based costs and has recorded a regulatory credit.

DERIVATIVE FINAN.CIAL INSTRUMENTS To help provide stable electric rates an~, to meet the forecasted power needs of its retail .customers reliably, SMUD enters into various physical and financial fixed price purchase contracts for electricity and natural. gas.

The.se fixed price contracts and swap agree~ents ai:e intended to hedge the exposure due to highly volatile

. commodity prices. SMUD also enters into interest rate swap agreements to reduce interest rate risk, or to enhance

' .

the relationship between the risk and return regarding SMUD's assets or debt obligations. SMUD utilizes these derivative financial instruments to mitigate its exposure to certain market risks associated with ongoing operations.

SMUD has established policies* set by an executive committee for the.use of derivative fin_ancial instruments for trading purposes. These contracts are evaluated pfu-suant to SGAS No_. 53 "Accounting and Financial Reporting for Derivative Instruments" (GASB No: 53) to determine whether they meet the definition of derivative instruments, and if so, whether they effectively hedge the expected cash flows associated with interesf rate and commodity p~ice risk exposures .

. SMUD applies.hedge accounting for derivatives that are deemed effective hedges. Under hedge accounting, the increase or (decrease) in the fair value 0f a hedge is reported as a Deferred Inflow or Deferred Outflow on the Consolidated Statements of Net Positfon. Derivatives that do not meet the effectiveness tests are deferred for rate-making purposes as regulatory assets or liabilities on the Consolidated Statements of Net Position (see Note 8).

During 2015 and 2014, SMUD executed numerous new gas and power related purchase agreements, some of which are recorded as hedging or investment derivatives and are therefore included in the following table. All hedging or investment derivatives are recorded at fair value on the Consolidated Statements of Net Po~ition.

For electricity and gas derivati~es, fair values are es.timated by comparing contract prices to forward market prices

_quoted by an independe!lt external pricing service. When external quoted market prices are not available for .

derivative contracts, SMUD uses an internally developed valuation model utilizing short term observable inputs.

For interest rate derivatives, SMUD subscribes to a financial information service that it uses to verify fair value estimates obtained from its counterparties.

SMUD hedges its interest costs. The interest rate swaps are designed to synthetically fix the cash flows associated with variable rate bonds (see Note 10).

SMUD hedges its power and natural gas costs so that it can offer predictable rates to its retail ele_ctric customers and support its credit rating. SMUD maintains a risk management program to control the price, credit, and operational risks arising from its_ power and natural gas market activities . .Under the program, authorized SMUD emplo_yees assemble a portfolio of swaps, futures, and 'forward contracts overtime with the. goal of making SMUD's purchased power and fuel budget more predictable.

These hedged risks include those related to interest rate and commodity price fluctuations associated with certain forecasted transactions, including interest rate risk on long-term debt, and forward purchases of gas and electricity to meet load.

Derivatives Not Designated as Hedging Instruments Gas and Electric Contracts. SMUD utilizes certain gas swap and electric swap agreements under GASB No. 53 not designated as hedging derivative instruments to mitigate exposure 'to changes in the market price of natural gas and electricity. The fair value of each agreement, excluding the actual settlements to be paid or received as of the end of the period, is recorded in either Current or Noncurrent Assets, Investment Derivative Instruments on the Consolidated Statements of Net Position if in an asset position or Current or N oncurrent Liabilities, Investment Derivative Instruments on the Consolidated Statements of Net Position if in a liability position. An offsetting amount is inciuded in Current or N oncurrent Regulatory Costs or *Regulatory Credit~ for future recovery in the Consolidated Statements of Net Position. The actual settlement payable is recorded in Accounts Payable on the Consolidated Statements of Net Position, and the actual settlement receivab_le is recorded in Receivabies - Net: Other on the Consolidated Statements of Net Position. The payments and receipts. of the actual settlement are recorded as Investment Expense in the Consolidated Statements-ofRevenues;Exp~nses and Changes in Net Position.

Sacramento -Municipal Utility District I 2015 Annual Report NOTES.TO CONSOLIDATED FINANCIAL STATEMENTS Interest Rate Contracts. SMUD utilizes certain interest rate swap agreements not designated as hedging derivative instruments under GASB No. 53 to mitigate exposure to changes in the fair value of variable rate debt resulting from fluctuations in interest ,rates. The fair value of each agreement, excluding the balance of in!erest to be *paid or received as of the end of the period, is recorded in either Current or Ncm~urrent Assets, Investment*

Derivative Instruments on the Consolidated Statements of Net Position if in an asset position or Cuirent"or Noncurrent Liabilities, Investment Derivative Instruments on the Consolidated Statements of Net Position if in a liabilify position.

An offsetting amo_unt is included in Current or Noncurrent Regulatory Costs or Deferred Outflows or Inflows of Resources in the Consolidated Statements of Net Position. The interest receivable is recorded in Receivables -

• Net: Other on the Con~olidated Statements of Net Position, and the accrued interest is recorded in Interest Payable on the Consolidated Statements of Net Position. The payments.or receipts of the actual settlement are recorded as Investment Expense in the Consolidated Statements of Revenues, Expenses and Changes in Net Position.

The Board has deferred recognition of the effects of reporting the fair value of Investment Derivative Instruments for rate-making purposes, and maint~ins regulatory accounts to defer the accounting impact of these accounting adjustme~ts (see "Note 8). Market values may have Qhanged significantly since December 31, 2015.

Interest Rate Risk. This is the risk that changes in interest rates will adversely affect the fair values of SMUD's interest rate swaps. SMUD is exposed to interest rate risk on its interest rate swaps.

- - . '

Basis Risk. This is the risk that arises when a hedged item and a derivative that is attempting to hedge that item are based on different indices. SMUD is exposed to basis risk ~hen it hedges its natural gas_ purchases, which are priced at various locations, with NYMEX futures contracts, which settle based on the price in Henry Hub, Louisiana.

SMUD enters into basis swaps to hedge against this risk.

Termination Risk. This is _the risk that a derivative will terminate prior to its scheduled maturity due tq a contractual event. Contractual events include bankruptcy, illegality, default, cfedit events upon merg<:;r, and other events. One aspect of termination risk is that SMUD would lose the hedging benefit of a derivative that becomes subject to a termination event: Another aspect of termination risk is_ that, if _at the time of termination the mark to market value of the derivative was a liability to SMUD, SMUD could be required to pay that amount to the counterparty.

Termination risk is associated with all of SMUD's derivatives up to the fair value amounts.

Credit Risk. This is the risk of loss resulting when the counterparty is unable or unwilling to fulfill its present and future financial obligations. SMUD can be exposed to significant counterparty credit risk on all derivative instruments~

SMUD seeks to minimize credit risk by transacting with creditworthy counterparties. SMUD has established and maintained strict counterparty credit guidelines. SMUD continuously monitors counterparty credit risk and utilizes numerous counterparties to diversify the exposure to potential defaults. Under certain conditions as outlined in SMUD's credit risk management policy, SMUD may require additional credit support under its tra~ing agreements.

Some of SMUD's derivative master agreements contain credit contingent provisions that enable SMUD to maintain unsecured credit as a result of positive investment quality credit ratings from each of the.major credit rating agencies.

If SMUD's credit rating were to be downgraded, there could be a step-down in SMUD's unsecured credit thresholds, and SMUD's counterparties would require additional collateral. If SMUD's credit rating were to decrease below investment grade, SMUD's unsecured credit thresholds would be reduced to zero, and counterparties to the derivative ins~ruments would demand ongoing full collateralization on derivative instruments in net out of the money positions (see Note 2).

. .

SMUD has a fixed-to-variable interest rate swap agreement with a notional amount of $131.0 million, which is equivalent to the principal amount of SMUD's 1997 Series K Electric Revenue Bonds. Under this swap agreement, SMUD pays a variable rate equivalent to the SIFMA Index (0.01 percent at December 31, 2015) and receives fixed rate payments of 5 .154 percent. In connection with the swap agr~ement, SMUD has a put option agreement, also with a notional amount of $131.0 million, which g!ves the counterparty the right to sell to SMUD, at par, either the a

1997 Series K Bonds, or portfolio of securities svfficient to defease the 1997 Series K Bonds. The exercise of the option terminates the swap at no cost to SMUD. The term of both the swap and the put is equal to the maturity of the 1997 Series K Bonds.

• Additional!y, S~ has two variable-to-fixed interest rate swap agreements with a combined notional amount of

.$192.4 million originally entered into for the purpose of fixing the effectiv~ interest rate associated with certain of its subordinated bonds that were refunded during 2008~ The notional values of the two swaps are *amortized over the

. life of the respective swap agreements. SMUD can terminate all swap agreements at any time, with payment or receipt of the fair market value of the swaps as of the date of termination. The obligations of SMUD under the swap agreements are not secured by a pledge of revenu~s of SMUD 's electric system or any other property of SMUD.

Component Unit Interest Rate s*wap Agreements. NCGA has three interest rate swap agreements, which are summarized as follows. The credit ratings listed are from S&P:

Credit Support Notional Provider Amount NCGA Fixed Floating Termination Credit (thousands) Pays Rate Rate Date , Rating

$ 54,320 Fixed 4.062% 67% of LIB OR +.60% 07/01117 BBB+

198,610 Fixed 4.304% 67% of.LIBOR +.72% 07/01/27 - BBB+

At December 31, 2015 NCGA has three variable-to-fixed interest rate swap agreements with a counterparty for the purpose of fixing the effective interest rate associated with the 2007 Series B Bonds. NCGA pays the counterparty a fixed rate on the notional amount and receives a floating rate equal to 67 percent of th~ three month LIBOR (0.61 percent at December 31, 2015) plus an interest rate spread, as specified in each swap agreement*. The total notional amount of the three swaps at December 31, 2015 was $318.8 millipn and was equivalent to the outstanding principal balance,on the NCGA Bonds. The swaps are amortized over the life of their respective swap agreements in a manner corresponding_ to the prinCipal repayment schedule of the NCGA Bonds. Early termination of the swaps would occur upon termination of the prepaid _agreement for any reason.

Upon early termination, the swaps would have no value to either party.

. Subordinated Electric Revenue Bonds. Payment of and interest on the Subordinated Electric Revenue Bonds is subordinate to the payment of the principal and interest on SMUD's Electric Revenue Bonds.

I Forward I SMUD ANNUAL REPORT 2015

Sacramento Municipal Utility District I 2015 Annual Repo*rt NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Variable Rate Bonds. SMUD's Variable *Rate Bonds bear interest at weekly rates, .01 percent at December 31, 2015. SMUD can elect to change the inter~st rate period or fix the interest rate, with certain. lirpitations. SMUD's Variable Rate Bonds can be put to SMUD's Trustee by the bondholders; however, ifthe bonds 9an't be: remarketed, SMUD has in place reimbursement agreements with Bank of America, State Street, and US Bank to enable'SMUD to pay off the bonds over five years. Accordingly, SMUD has recorded such bonds as Long-Term Debt, less

• amounts scheduled for redemption within one year.

Component Unit Bonds. The component units of SMUD have each issued bonds to finance their respective projects. The revenue stream to pay CVFA, SCA, and SFA bonds' debt service is provided by "take-or-pay" power purchase agreements, and is therefore not dependent. on the successful _operation of the proje<;:ts. SMUD guarantees to inake payments sufficient to pay princip~l and interest and all other payments required to be.made under the CVFA, SCA, and SFA's indenture of trust. CVFA, SCA, and SFA are not required to repay SMUD for any amounts paid under thjs guarantee. The revenue stream to pay NCGA bonds' debt service is provided by a ~'take-and-pay"

• purchase agreement Therefore, principal and interest associated with these bond~ are paid solely from the revenues and receipts collected in connection with the operation of the project. Most operating revenues earned by NCGA are collected from SMUD in connection with the sale of gas to SMUD. The ability for NCGA to service debt is dependent_ on various parties (partfoularly MSCG, as gas supplier) meeting their contractual obligations.

Callable Bonds~ SMUD has $794.9 million of Electri~ Revenue Bonds that are currently callabl~, $450.0 million

• of which are fixed rate Build America Bonds debt and $344,9 million of subordinate Variable Rate Demand Notes.

SMUD also has $860.8 million of bonds that bec9me callable from 2018 through 2024, and the~e bonds can be called until maturity.

Collateral. The principal and intere-st on SMUD's bonds are payable exclusively from, and are collateralized by a pledge of, the net revenues of SMUD's electric system. Neither the credit nor. the taxing power of SMUD is pledged.

to the paymellt of the bonds and the general fund of SMuD is not liable for the payment thereof.

Covenants. SMUD's bond resolutfons contain various covenants that)nclude requirements to .11_?.aintain minimum debt service coverage ratios, certain other financial ratios, stipulated.minimum funding of~evenue bond reserves, .

and various other requirements including a rate covenant to raise rates to maintain minimum debt service coverage.

,,

SMUD has pledged future net electric revenues, component unit net project revenues, and net gas supply prepayment revenues to repay, in electric revenue, componeti.t unit project revenue, and gas supply prepayment revenue*bonds issued from 1997 through 2015. Proce~ds from the bonds provided financing for various capital improvement projects, component unit capital projects, and the prepayment of a twenty-year supply of natur~l gas.

The bonds are payable solely from the net revenues generated by SMUD's electrical sales, compon~nt unit projec~

revenues, arid gas supply prepayment revenues and are payable through 2041 at December 31, 2015 ..

The Rancho Seco decommissioning liability relates to the nuclear decommissioning of the former 913 MW nuclear power plant, which tefllJ.inated commercial operations in 1989 and the separately licensed Independent Spent Fuel Storage Facility (ISFSI). Nuclear decommissioning is the process of safely removing nuclear facilities from service and reducing res.idual radioactivity to a level that pe~mits termination of the Nuclear

. Regulatory Commission (NRC) license, and release of the property for unrestricted use. The NRC has ~pproved SMUD's decommissioning plan for the nuclear power plant, whicJ;i. delineates a phased process, and the first phase of physical work was completed in 2008. Decommissioning ofthe'-ISFSI will occur after the DOE removes the spent nuclear fuel and high level waste from the site.

In 2009, the NRC released all of the land formerly under the Part 50 li?ense for unrestricted u~e with the excepti9n of the 1 acre fenced area around the Interim Onsite Storage Building that was previously used to store low-level radioactive waste produced during the decommissioning Gf the nuclear reactor facility. This waste was disposed of in 2014. The decommissioning of that remaining facility began in 2015 and when ~ompleted, will result in termination of the former operating license issued under Part 50.

The DO~, under the Nuclear Waste Policy Act of 1?82, is respo~sible for permanent disposal of spent nuclear fuel and high-level radioactive waste which are currently in storage at the ISFSI..SMUD has a contract w_ith the DOE.

for the removal and disposal of spent nuclear fuel and high-level (~reater than class "C": GTCC) radioactive waste.

All of SMUD's spent fuel and GTCC waste are currently stored in sealed canisters in the ISFSI. However, the date when fuel and GTCC waste removal will be complete is uncertain. In 2010, the DOE formally withdrew the application for licensing ofYucca Mountain as a high-level waste repository, essentially rempving y-ucca Mountain as an option for disposal ofSMUD's used nuclear fuel. The DOE also announced in January 2010 the creation of a Blue Ribbon Commission to study alternatives for developing a repository for the nation's used nuclear fuel. The Co~ission provided a final report on alternatives in January 2012. The DOE e~aluated the recommendations and published the report "Strategy-for the Management and Disposal of Used _Nuclear Fuel and High-Level Radioactive Waste'" in January 2013. The next phase of the process will be for Congress and the President of the United States to consider the recommendations and enact legislation to implement the recommendations. At this time, there is no credible information available to determine when the DOE would remove the used* nuclear fuel from the Rancho Seco facility. The ISFSI will remain under the regulation of the NRC until the nuclear fuel and GTCC radioactive_

waste are removed and the site is decommissioned.

Sacramento Municipal Utility District I 2015 Annual Report NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Asset Retirement Obligations (ARO). These financial statements reflect SMUD's current estimate of its obligation for the cost of deconup.issi~ning (including the cost of managing the Storage Facility until it can be decomillissioned) under the ~equirements ofFASB ASC 410, based on studies completed each year. Each year, SMUD evaluates the estimate of costs. of decommissioning and there was a decrease in costs in the 2015 study. The ARO estimate assumes all spent nuclear fuel will be remo_ved from the site by 2035.

The employer is required to contribute the difference between the actuarially determined rate and the contribution rate of employees. For the PERS fiscal year ended June 30, ~015 and 2014, the average active emplgyee contribution rate is 6.9 percent of annual pay, and the employer's contribution rate is 12.0 percent and 10.9 percent of annual payroll, respectively. Employer contribution rates may change if plari contracts are amended.

For the year ended December 31, 2015 and 2014, SMUD made contributions recognized by the pension plan in the amount of $30.5 million and $31.4 ~illion, which includes $8.0 ~illim1 and $9.9 million of employer paid employee contributions,-respectively.

'

Net Pension Liability. SMUD's NPL at December 31, 2015 and 2014 was measured at June 30, 2015 and 2014,

• respectively. The total pension liability used to. calculate the NP& was determined by actuarial valuations as of June 30, 2014 and 2013 rolled forward using generally accepted actuarial procedures to the June 30, 2ol5 and 2014 measurement dates.

Sacramento Municipal Utility District I 2015 Annual Report

• NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Actuarial Methods and Assumptions. The act.uarial methods and assumptions used *for the December 31, 2015 and December 31, 2014 total pension liabilities are as follows:

'

Actuarial Cost Method Entry age.normal Discount rate 'Z.65% (2015), 7.5% (2014)

Inflation 2.75%

Salary increases Varies by entry age and service Investment rate of return 7.65%, net of pension plan investment; includes inflation (2015) 7.5%, net of pension plan investment and administrative expenses; includes infla!ion (2014)

Mortality Rate Table The mortalify table used W!lS developed based on PERS' specific data. The table includes 20 years of mortaiity improvements using Sodety of Actuaries Scale BB.

Post Retirement Benefit Increase Contract COLA up to 2.75% until Purchase Power Protection Allowance Floor on Purchasing Power applies, 2.75% thereafter . '

All other actuari~I assumptions used for both years were based on the results of an actuarial experience study for the_period from 1997 to 2011, including updates to salary increase, mortality and retirement rates.

Discount Rates. The discount rates used to measure the total pension liability for the year ended December 31, 2015 apd 2014 was 7.65 percent and 7.5 percent, respectively. To determine whether the municipal bond rate should be used in the calculation ~fa discount rate for each plan, PERS stress tested plans that would most likely result in a discount rate that wo~ld be different from the actuarially assumed discount rate. Based on the testing, none of the tested p~ans run out of assets. Therefore, the 7.65 percent and 7.5 percent discount rates used for the respective valuations are adequate and the use of the municipal bond rate calculation is not necessary. The long-term expected discount rates of 7 .65 percent and 7.5 percent for the respective valuations are appli~d to all plans in the Public Employees Retirement Fund.

J['he long-term-expected rate ofreturn on pension plan investments was determined using a building-block method in which best-estimate ranges of expected future, real rates of return (expected returns, net of pension plan investment, expense and inflation) are developed for*each major asset class. Using historical returns of all the funds' asset

.classes, expected compound (geometric) returns were calculated over the short-term (first 10 years) and the long-term (11- 60 years) using a building-block approach.

The table below reflects long-term expected real rate of return by asset class. The rate of return was calculated using the .capital market assumptions applied to* determine the discount rate ~nd asset allocation. The target allocation shown below was adopted by the PERS' Board effecti\re on July 1, 2014.

Current Target Real Return

• Real Return Asset Class. Allocation Years 1-10 Years 11+

. Other Plans. SMUD provides its employees with two cash deferred compensation plans: one pursuant to Internal Revenue Code (IRC) S~ction 40l(k) [401(k) Plan] and one pursuant to IRC Sectjon 457 (457 Plan) (collectively, the-Plans). The Plans are contributory plans in which SMUD's employees contribute the funds. Each of SMUD's eligible full-time or permanent part-time employees may participate in either or both Plans, and amounts contributed

ire ve~ted immediately. Such funds are held by a Trustee in trust for the employees upon retirement from SMUD service and, accordingly, are not ,subject to the general claims of SMUD's creditors. SMUD is responsible for ensuring compliance with IRC requirements concerning the Plans and has the fiduciary duty of reasonable care in the selection of investment alternatives, but neither SMUD, nor its Board or officers have any liability for market variations in th~ Plans' asset values. SMUD employees are responsible for determining how th,eir funds are to be

' . .

invested and pay all ongoing fees related to the Plans. The Plans are currently not subject to discrimination testi_?g, nor the requirements of the Employee Retirement Income Security Act of 1974. SMUD employees participating in the Plans are allowed to contribute a pqrtion of their gross tncome not to exceed the annual dollar limits prescribed by the IRC.

SMUD makes annual contributions to the 401 (k) Plan on behalf of certain employees pursuant to a memorandum of unde~standing with both of its ~ollective bargaining units. SMUD also matches non-represented employee contributions to the 401(k) Plan up to a set amount. SMUD made contributions into the 401(k) Plan of$3.5 rnillio~

in 2015 and $2.9 million in 2014. SMUD does not match employee contributions, nor make contributions on behalf of its employees to the 457 Plan. Participating employees made contributions into both Plans t9taling $185 million in 2015 and $16.8 million in 2014.

NOTE 14. OTHER POSTEMPLOYMENT BENEFITS SMUD .

provides postemployment healthcare benefits, in accordance with SMUD'policy

. .

and negotiated agreements with employee representation groups in a single employer defined benefit plan, to _all emp~oyees who retire from SMUD, and their dependent~. SMuD also provides postemployment healthcare benefits to covered employees.who are eligible for disability retirement. SMUD contributes the full cost of coverage for retirees hired before Jan\lary 1, 1991, and a portion of the cost based on credited years of service for retirees hired after Janu_ary 1, 1991. SMUD also contributes a portion of the costs of coverage for these retirees' dependents. Retirees are required to contribute the portion that is not paid by S_MUD. The benefits, benefit levels, retiree contributions and employer contributions are governed by SMUD and can be amended by SMUD through its personnel manual_ and union contracts. At June 30, 2015, 4,962 posteinployment participants, including retirees, spouses ofretirees, surviving sp~tises, and eligible dependents, were eligible to participate in SMUP's healthcare benefits program~

OPEB arises from an exchange of salaries- and benefits for employee services rendered, and refers to

• postemployment benefits other than pension benefits such as postemployment healthcare benefit~. SMUD

• considers the following benefits to-be OPEB: Medical, Dental and Long-Term Disability.

Plan Description. SMUD is a member of the California Employers Retiree Benefit Trust (CERBT) for prefunding of OPEB obligations. The CERBT Fund is. an IRC Section 115 Trust set up for the purpose of receiving employer contributions to prefund health and other.postemployment benefits for retirees and their beneficiaries. The plan _is an agent multiple employer plan administered by PERS, which provides medical, dental and long-term disability benefits for retirees and thefr beneficiaries. Any changes to these benefits would be approved by SMUD's Board and union c~mtracts. To obtain a CERBT report, please contact PERS at 888-CALPERS .

Sacramento Municipal Utility District I 2015 Annual Report NOTES To- CONSOLIDATED FINANCIAL STATEMENTS '

'

The funding; of a plan occurs when the following events take place: the employer makes payments of.benefits directly to or on pehalf of a retiree or beneficiary; the employer makes premium payments to an insurer; or the_

employer irrevocably transfers assets to a trust or other third party acting in the role of trustee, where the plan assets

• are dedicated to the sole purpose of the payments *of the plan benefits, and creditors of the government ao not have access to those assets.

Funding Policy. SMUD has elected to net fund to PERS, so the contributions are the Annual Required Contribution (ARC) less the estimated cash flow for retiree benefit costs for each year. SMUD ca_n elect to put in additional contributions into the trust, and in 2015 and 2014 funded an additional $22.0 million and $40.0 million to the_ .

CERBT, respectively. In 2015 and 2014, the net ARC contribution to the CERBT was $6.6 million and $6.8 million, respectiyely. During 2015 -and 201{ SMUD made healthcare benefit contributions by paying 'actual medical costs of $17.4 million and $23. 6 million, respecti~ely.

Funding Status and Funding Progress. At June 30, 2015 and 2014, SMUD estimates that the actuarially determined accumulated postemplbyment benefit obligation was approx}mately $319 .4 million and $505. i'million, .

respectively. At June 30, 2015 and 2014, the pfan was 55.2 and 25.6 percent funded, respectively. The covered payroll (annual payroll of active employees covered by the plan) at June 30, 2015 and 2014, was $191.4 million and $187.2 million, respectively.The ratio of the UAAL to covered payroll was 74.8 percent at June 30, 2015.

Annual OPEB Cost. The annual OPEB cost (expense) is calculated l;>ased on the ARC of the employer, an amount

. actuarially determined in accordance with the p~rameters of SGAS No." 45, Accounting and Financial Reporting by Employers for Postemployment Benefits Other Than Pensions." The ARC -represents ~ level of funding that,

. . I if paid on an ongoing basis, is projected to cover the normal cost each year and amortize any .unfunded actuarial liabilities (or funding excess) over a period not to exceed 30 years. For 2015, SMUD's annual OPEB Cost (expense) was $27.7 million. -

. .

Actuarial Methods anq Assumptions. Projections of benefits for financial reporting purposes are based on the substantive plan (the plan as understood by the employer and plan members)and include the types of benefits provided at the tin;ie of each valuation and the historical pattern of sharing the benefit costs between the employer and plan members to that point. The actuarial methods and assumptions used include techniques that are designed

_to reduce the effects of short-term volatility in actuarial accrued liabilities and the actuarial value of assets, consistent with the long-term perspective of the calculations.

. .

The entry.age normal was u~ed in the June 30, 2015 and 2014 actuarial valuation. The actuarial assumptions used for the June 30, 2015 and 2014 valuations were 7.25 percent an4 7.36 investnlent rate, ofreturn (net ofadrnini_strative a

expenses), respectively, and 3.0 percent inflation assumption for both years. The actuarial assumptions for an -

annual healthc~re cost trend growth rate for 2015 and 2016 was based on actual premiums and ranged from 7 .0 to 7.2 percent for 2017. The UAAL will be amorti~ed as a percentage of payroll over: a closed 30-year period. At June 30, 2015 and.2014 the actuarial value,of the assefs was $176.2 and $129.5 million, respectively.

Ac~arial valuations of an ongoing plan involve estimates of the value of reported amounts and assumptions about the propability of occurrei;ice of events far into tlie future. Examples include assumpti,:ms about future employment, mortality and the healthcare cost trends. Amounts determined regarding the funded stattis of the plan and the ARC of the employer.are subject to continual revision as actual results are compared with past ef(.pectations and new estimates are made about the future. The schedule of funding progress, presented as RSI following the notes to the financial statements, presents mul'tiyear trend information that shows whether the actuarial va!ue of plan assets is increasing or decreasing over time relative to the actuarial accrued Jiabilities for benefits.

Solano Wind. In December 2011, SMUD e~tered into an agreement to sell the Solano Wind Phase 3 project (see Note 2). SMUD will buy all output from the plant under the terms of the Power Purchase Agreement. The

• plant.began commercial operation in April 2012 and SMUD receives all output generated. Under the terms of the various agreements, SMUD lias the option to- buy _the plant back upon the sixth, ei~hth, or fifteenth anniversary of the commercial operation date or the end of the delivery term.

Gas Price _Swap Ag~eements. SMDD has entered into numerous variable to fixed rate swaps with notional amounts totaling 127,727,500 Dths for the purpose of fixing-the rate ori SMUD's natural gas purchases for its gas-fueled power plants and gas indexed electric contracts. These gas price swap agreements result _in SMDD p~ying fixed rates ranging from $2.82 to $7*.l 7 per Dth. The swap agreements expire periodically from January

, 2016 through December 2022.

Gas Transport Capacity Agreements. SMUD has numerous long-term natural gas transport capacity agreements

. with Canadian.and U.S. companies to transport natural gas to SMUD's natural gas-fired power plants from the supply basins in Alberta to the California-Oregon border arid from supply basins in the southwest and Rocky Mountains to the Southern California border. These gas transpmt capacity agreements provide Tor the delivery of gas into SMUD-owned pipeline capacity within California. The gas transport capacity agreements provide SMUD with 56,600 Dth per day (Dth/d) of natural gas pipeline capacity from the North, including the Canadian Basins through 2023 and 54,000 Dth/d from the Southwest or Rocky Mountain Basins through at least 2018 ..

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS NOTE 17. CLAIMS AND CONTINGENClE'S F~RC Administrative Proceedings. SMUD is involved in a number of EERC administrative proceedings related to .

the operation ofwholes!ile energy markets,-regional transmission planning, gas transportation, and the development ofNERC reliability standards. While these proceedings are complex and numerous, they generally fall into the following categories: (i) filings initiated by the California Independent System Operator Corporation (CAISO) (or other market participants) to adopt/modify the CAISO Tariff and/or establish market design and behavior rules; (ii) filings initiated by existing transmission owners (i.e. PG&E !ind the other Investor Owned Utilities) to pass-through costs to their *existing wholesale transmission customers; (iii) filings initiated by FERC or market participants to establish market design and behavior rules or_ to complain about or investigate market behavior by certain market participants; (iv)° filings initiated by transmission owners under their transmission owner tariffs for the purpose of establishing a regional transmission planning process; (v) filings initiated by providers of finp. gas transportation service under the Natural Gas Act; and (vi) filings initiated l?y NERC tp develop reliability standards applicable to owners, users, and operators of the bulk electric system. SMUD's m~nagement believes that the ultimate resolution of these matters will not have a material adverse effect on SMUD's financial position, liquidity or results of operations.

Construction Matters. SMUD contracts with various firms to design and construct facilities for SMUP. Currently, SMUD is party.to various claims, legal actions and,eomplaints ~elating to such construction projects. SMUD's -

management believes that the ultimate resolution of these matters will not have a material adverse effect on SMUD's financial position, liquid_ity or results of operations.

Environmental Matters. SMUD was one of many potentially responsible parties that had been named in a number of actions relating to environmental claims and/or complaints. SMUD has resolved these environmental claims ancl/or complaints and entered into settlement agreements and/or consent orders. These settlement agreements and consent orders have statutory reopener provisions. which allow regulatory agencies to seek additional funds for environmental remediation under certain limited circumstances. While SMUD believes it is unlikely that any of the prior settlement agreements or consent ord~rs will be reopened, th~ possibility exists. ~f any of the settlement agreements or consent *orders is reopened, SMUD management does not believe that the outcome will have a material adverse impact on SMUD's financ~al position, liquidity or results of operations.

North City Remediation. In 1950, SMUD purchased..property (North City Site) from the City of Sacra~ento and the Western Railroad Company. Portions of the North City Site prior to the sale had been operated as a municipa~

landfill by the City of Sacramento. SMUD currently operates a bulk substation on the North City Site~ SMUD intends to assure compliance with State standards at closed lanafill sites and is in the process of determining the appropriate remediation for the North City Site. In 2009, SMUD recorded a liability related to the investigation, design and remediation necessary for the North City Site in the amount of $12.0 million estimated for the entire project. As the owner of the North City Site, SMUD will have a role in the remediation selection and activities, as may those who operated or used the North City Site for landfill purposes. SMUD has estimated its exposure to such costs based on its proportionate share of the remedy. However, should others become unable to participate due to insolvency or otherwise unable to pay their share of the costs, SMUD's share ofremediation costs wou_ld increas~. SMUD's management does not believe this will occur. Even if SMUD were to ultimately be responsible for all remediation costs associated with the North City Site, SMUD management believes that the outcome of these remediation costs will not have a material adverse impact on SMUD's financial position, liquidity or

. results of operations.

s.acramento Municipal Utility District I 2015 Annual Report NOTES TO CONSOLIOATED FINANCIAL STATEMENTS Former Community Linen Rental Services. (Community) Property. In 1981, SMUD purchased property from Community located at 1824 and.1826 61st Street (Site). That same year, Community sold its linen business and equipment to Mission Laundry (Mission). SMUD continued to lease portions of the property to Mission until 1985. SMUD settled with these businesses and waived a potential future legal claim for cleanup funding. The property to the north of the Site was owned by f<ramer Carton Company (Kramer) and used for 60 years as a carton manufacturing facility. In 2009, Kramer filed for bankruptcy protection from its creditors. The Kramer property was encumbered by a first and second deed of trust, where the second deed of trust was held by Willamette Capital Management, Ltd. (Willamette). Willamette purchased the note on the first deed of trust. In 2011, Willamette foreclosed on the Kramer property and now holds title to the Kramer property. Based on environmental investi.gations, it has been determined that there is contamination at the Kramer property, ~t the Site, and at areas south of the Kramer property. The contamination appears to emanate primarily from the Site, with some, albeit minor, contribution from the Kramer property. Preliminary environmental investigations of the Kramer property, the Site and areas south of the Kramer property indicate that total remediation costs will likely e~ceed $2.0 million. SMUD has recorded a liability for the estimated costs of the remediation. Although SMUD does not believe that it is the source of the contamination, it appears that one or more of its predecessors in.interest may be the cause of most of the contamination. Moreover, since Kramer is bankrupt and Willamette contends it is exempt from liability under*

a secured creditor exemption, it is unclear whether it would be beneficial for SMUD to take legal action for contribution. SMUD has made an offer to purchase the Kramer property at a.cost reflecting the proportionate share of the parties' predecessors' respective contributions to the contamination, giving SMUD an asset with value that will materialize after the cleanup. Even if SMUD were to ultjmately be responsible for all remediation costs associated with the Site, SMUD's management believes that the remediation of the Site will not have a material adverse impact on SMUD's financial position, liquidity or results of operations.

Buena Vista Biomass Power LLC. On_ October 2, 2015, SMUD informed Buena Vista Biomass Power, LLC (Buena Vista) of its intent to terminate its existing power purchase agreement (PPA) in accordance with the terms of the PPA, due to Buena Vista-'s failure to meet its contractual obligations. On December 4, Buena Vista informed SMUD ihat it disputed SMUD's right to terminate, and threate_ned to pursue arbitration if it were forced to shut d<:Jwn the Project. On December 21, SMUD issued Buena Vista a termination notice, effective December 31, 2015.

At the same time, the parties entered into a short t~rm power purchase agreeme~t effective January 1,'2016, while the parties attempted to negotiate a longer term arrangement on commercial terms acceptable to both parties. The short term agreement will expire on February 29, 2016. SMUD is unable to predict at this time whether Buena Vista will bring a claim under the terminated PPA, to the extent that the parties are not successful in negotiating a replacement PPA. However, SMUD management does not believe that the *outcome will have a materi~l adverse impact on SMUD's f~nancial position, liquidity or results of operations.

Sacramento Municipal Utility District I 2015 Annual Report NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Patua Project LLC. In 2010, SMUD entered into a power purchase agreement. with Patua Project LLC, a subsidiary at the time of Vulcan Power Company, to deliver 116 MW of geothermal power in three phases* from.

a geothermal resource area east of Reno, Nevada. The project was soon sold to Gradient Resources (Gradient).

The project subsequently exp.erienced technical difficulties stemming from poor permeabillty of the subterranean resource that led to repeated delays and eventual downsizing of the project to no more than 38.67 MW in two phases. Gradient finally achieved commercial operation of Phase 1 more than a year behind schedule and well below the intended capacity, which led to insolvency. Consequently, the project was sold to Cyrq Energy (Cyrq) in November 2015. Soon after closing, SMUD discovered that Gradient delivered a portion of non-renewable power to SMUD in breach of the PPA, and has made claims upon Cyrq damages. In response, Cyrq has pressed several of its own financial claims that potentially exceed SMUD's. The parties are now engaged in settlement

, discussions, which if unsuccessful, could lead to arbitration. Even if Cyrq is successful in arbitration, SMUD management does not believe that the outcome will .have a mat~rial adverse impact on SMUD's financial position, liquidity or results of operations.

,Other Matters. Currently, SMUD is party to various claims, legal -actions and complaints relating to its operations, ipcluding but not limited to: property damage and personal injury, contract disputes, torts, and employment matters.

SMUD's management believes that the ultimate resolution of these matters will not have a material adverse effect on SMUD's financial position, liquidity or results of operations.
