Forward-looking statements should not be read as a guarantee of future performance or results, and will not necessarily be accurate indications of the times at, or by, which such performance or results will be achieved, if at all. Forward-looking statements are subject to risks and uncertainties that could cause actual performance or results to differ materially from those expressed in or suggested by the forward-looking statements. As of the date hereof, we have bookings and financing for only a small percentage of the orders needed to achieve our 2014 megawatt projections and therefore expect the megawatts deployed in 2014 to be sourced almost exclusively from new deployments of solar systems not currently under contract. In order to meet our projections, we will need to substantially expand our workforce, increase our installation efficiency and exceed our existing bookings rate relative to what we have achieved to date. Additional key risks and uncertainties include the level of demand for our solar energy systems, the availability of a sufficient, timely, and cost-effective supply of solar panels and balance of system components, the effects of future tariffs and other trade barriers, changes in federal tax treatment, the effect of electric utility industry regulations, net metering and related policies, the availability and amount of rebates, tax credits and other financial incentives, the availability and amount of financing from fund investors, the retail price of utility-generated electricity or the availability of alternative energy sources, risks associated with SolarCity's rapid growth, risks that consumers who have executed energy contracts included in reported nominal contracted payments remaining and backlog may seek to cancel those contracts, assumptions as to retained value under energy contracts and contract renewal rates and terms, including applicable net present values, performance-based incentives, and other rebates, credits and expenses, SolarCity's limited operating history, particularly as a new public company, changes in strategic planning decisions by management or reallocation of internal resources, completion of preparation of financial statements and general market, political, economic and business conditions. You should read the section entitled "Risk Factors" in our most recent Quarterly Report on Form 10-Q, which has been filed with the Securities and Exchange Commission, which identifies certain of these and additional risks and uncertainties. We do not undertake any obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future developments or otherwise, except as otherwise required by law.

"MW" or "megawatts" represents the DC nameplate megawatt production capacity.
 
"Backlog" represents the aggregate megawatt capacity of solar energy systems not yet deployed as of the date specified pursuant to Energy Contracts and contracts for solar energy system direct sales executed as of such date.
"Customers" includes all residential, commercial and government buildings where we have installed or contracted to install a solar energy system, or performed or contracted to perform an energy efficiency evaluation or other energy efficiency services.
"Energy Contracts" includes all residential, commercial and government leases and power purchase agreements pursuant to which consumers use or will use energy generated by a solar energy system that we have installed or contracted to install. For landlord-tenant structures in which we contract with the landlord or development company, we include each residence as an individual contract. For commercial customers with multiple locations, each location is deemed a contract if we maintain a separate contract for that location.
"MW Booked" represents the aggregate megawatt production capacity of solar energy systems pursuant to customer contracts signed during the applicable period net of cancellations during the applicable period. This metric includes solar energy systems booked under Energy Contracts as well as solar energy system direct sales.
"MW Deployed" represents the megawatt production capacity of solar energy systems that have had all required building department inspections completed during the applicable period. This metric includes solar energy systems deployed under Energy Contracts as well as solar energy system direct sales.
"Nominal Contracted Payments Remaining" equals the sum of cash payments obligated to be paid to us under our Energy Contracts over the remaining term of such contracts. This metric includes Energy Contracts for solar energy systems already deployed and in Backlog. As an example, if a customer is 2 years into her 20 year contract, then 18 years of contract payments remain. As an additional example, if a customer chose to pre-pay her Energy Contract, then it is included in Nominal Contracted Payments Remaining only while it is in Backlog as the pre-payment has not been received. Payments for direct sales are not included. 
"Retained Value" forecast represents the sum of both "Retained Value under Energy Contract" and "Retained Value Renewal." Retained Value Under Energy Contract represents the forecasted net present value of Nominal Contracted Payments Remaining and estimated performance-based incentives allocated to us, net of amounts we are obligated to distribute to our fund investors, upfront rebates, depreciation, renewable energy certificates, solar renewable energy certificates and estimated operations and maintenance, insurance, administrative and inverter replacement costs. This metric includes Energy Contracts for solar energy systems deployed and in Backlog. Retained Value of Renewal represents the forecasted net present value of the payments SolarCity would receive upon Energy Contract renewal through a total term of 30 years, assuming all Energy Contracts are renewed at a rate equal to 90% of the contractual rate in effect at expiration of the initial term. This metric is net of estimated operations and maintenance, insurance, administrative and inverter replacement costs and includes Energy Contracts for solar energy systems deployed and in Backlog. Our calculation of retained value assumes a discount rate of 6%.
"Retained Value per Watt" is computed by dividing cumulative retained value as of such date by the sum of total MWs deployed under Energy Contracts as of such date plus MWs booked under Energy Contracts as of such date but not yet deployed.
"Undeployed Tax Equity Financing Capacity" represents a forecast of the amount of MW that can be deployed based on committed available tax equity financing for Energy Contracts.
