International.
In general, our international markets are less advanced with respect to the current technologies deployed for wireless services.
As a result, demand for our communications sites is driven by continued voice network investments, new market entrants and initial 3G data network deployments.
For example, in India, nationwide voice networks continue to be deployed as wireless service providers are beginning their initial investments in 3G data networks, as a result of recent spectrum auctions.
In Mexico and Brazil, where nationwide voice networks have been deployed, some incumbent wireless service providers continue to invest in their 3G data networks, and recent spectrum auctions have enabled other incumbent wireless service providers and new market entrants to begin their initial investments in 3G data networks.
In markets such as Chile and Peru, recent spectrum auctions have attracted new market entrants, who are expected to begin their investment in deploying nationwide voice and 3G data networks.
We believe demand for our tower sites will continue in our international markets as wireless service providers seek to remain competitive by increasing the coverage of their networks while also investing in next generation data networks.
Rental and Management Operations New Site Revenue Growth.
During the year ended December 31, 2010, we grew our portfolio of communications sites through acquisitions and construction activities, including the acquisition and construction of approximately 7,800 sites.
We continue to evaluate opportunities to acquire larger communications site portfolios, both domestically and internationally, that we believe we can effectively integrate into our existing portfolio.
## Table 0 ##
(1) The majority of sites acquired or constructed internationally during 2010 and 2009 were in India and our newly launched operations in Chile, Colombia and Peru.
Network Development Services Segment Revenue Growth.
As we continue to focus on growing our rental and management operations, we anticipate that our network development services revenue will continue to represent a small percentage of our total revenues.
Through our network development services segment, we offer tower-related services, including site acquisition, zoning and permitting services and structural analysis services, which primarily support our site leasing business and the addition of new tenants and equipment on our sites.
Rental and Management Operations Expenses.
Our rental and management operations expenses include our direct site level expenses and consist primarily of ground rent, property taxes, repairs and maintenance and utilities.
These segment level expenses exclude all segment and corporate level selling, general, administrative and development expenses, which are aggregated into one line item entitled selling, general, administrative and development expense.
In general, our rental and management segment level selling, general and administrative expenses do not significantly increase as a result of adding incremental tenants to our legacy sites and typically increase only modestly year-over-year.
As a result, leasing additional space to new tenants on our legacy sites provides significant incremental cash flow.
In geographic areas where we have recently launched operations or are focused on materially expanding our site footprint, we may incur additional segment level selling, general and administrative expenses as we increase our presence in these areas.
Our profit margin growth is therefore positively impacted by the addition of new tenants to our legacy sites and can be temporarily diluted by our development activities.
REIT Election.
As we review our tax strategy and assess the utilization of our federal and state NOLs, we are actively considering an election to a REIT for U. S.  federal and, where applicable, state income tax purposes.
We may make the determination to elect REIT status for the taxable year beginning January 1, 2012, as early as the second half of 2011, subject to the approval of our board of directors, although there is no certainty as to the timing of a REIT election or whether we will make a REIT election at all.

Derivative Instruments Effective Jan.  1, 2009, Xcel Energy adopted new guidance on disclosures about derivative instruments and hedging activities contained in ASC 815 Derivatives and Hedging, which requires additional disclosures regarding why an entity uses derivative instruments, the volume of an entity’s derivative activities, the fair value amounts recorded to the consolidated balance sheet for derivatives, the gains and losses on derivative instruments included in the consolidated statement of income or deferred, and information regarding certain credit-risk-related contingent features in derivative contracts.
Xcel Energy and its utility subsidiaries enter into derivative instruments, including forward contracts, futures, swaps and options, for trading purposes and to reduce risk in connection with changes in interest rates, utility commodity prices and vehicle fuel prices, as well as variances in forecasted weather.
See additional information pertaining to the valuation of derivative instruments in Note 15 to the consolidated financial statements.
Interest Rate Derivatives — Xcel Energy and its utility subsidiaries enter into various instruments that effectively fix the interest payments on certain floating rate debt obligations or effectively fix the yield or price on a specified benchmark interest rate for a specific period.
These derivative instruments are generally designated as cash flow hedges for accounting purposes.
At Dec.  31, 2009, accumulated OCI related to interest rate derivatives included $1.1 million of net gains expected to be reclassified into earnings during the next 12 months as the related hedged interest rate transactions impact earnings.
During the fourth quarter of 2009, Xcel Energy settled a $25 million notional value interest rate swap at SPS.
This interest rate swap was not designated as a hedging instrument, as such, gains and losses from changes in the fair value of the interest rate swap were recorded to earnings.
Commodity Derivatives — Xcel Energy’s utility subsidiaries enter into derivative instruments to manage variability of future cash flows from changes in commodity prices in their electric and natural gas operations, as well as for trading purposes.
This could include the purchase or sale of energy or energy-related products, natural gas to generate electric energy, gas for resale and vehicle fuel.
At Dec.  31, 2009, Xcel Energy had various vehicle fuel contracts designated as cash flow hedges extending through December 2012.
Xcel Energy’s utility subsidiaries also enter into derivative instruments that mitigate commodity price risk on behalf of electric and natural gas customers but are not designated as qualifying hedging transactions.
Changes in the fair value of non-trading commodity derivative instruments are recorded in OCI or deferred as a regulatory asset or liability.
The classification as a regulatory asset or liability is based on commission approved regulatory recovery mechanisms.
Xcel Energy recorded immaterial amounts to income related to the ineffectiveness of cash flow hedges for the years ended Dec.  31, 2009 and 2008.
At Dec.  31, 2009, accumulated OCI related to vehicle fuel cash flow hedges included $3.0 million of net losses expected to be reclassified into earnings during the next 12 months as the hedged transactions occur.
Additionally, Xcel Energy’s utility subsidiaries enter into commodity derivative instruments for trading purposes not directly related to commodity price risks associated with serving their electric and natural gas customers.
Changes in the fair value of these commodity derivatives are recorded in income, subject to applicable customer margin-sharing mechanisms.
Xcel Energy had no derivative instruments designated as fair value hedges during the period ended Dec.  31, 2009.
Therefore, no gains or losses from fair value hedges or related hedged transactions were recognized for the period.

Fair Value Measurements Effective Jan.  1, 2008, Xcel Energy adopted new guidance for recurring fair value measurements contained in ASC 820 Fair Value Measurements and Disclosures which provides a single definition of fair value and requires enhanced disclosures about assets and liabilities measured at fair value.
A hierarchal framework for disclosing the observability of the inputs utilized in measuring assets and liabilities at fair value was established by this guidance.
The three levels in the hierarchy and examples of each level are as follows: Level 1 — Quoted prices are available in active markets for identical assets or liabilities as of the reported date.
The types of assets and liabilities included in Level 1 are highly liquid and actively traded instruments with quoted prices, such as common stocks listed by the New York Stock Exchange and commodity derivative contracts listed on the New York Mercantile Exchange.
Level 2 — Pricing inputs are other than quoted prices in active markets, but are either directly or indirectly observable as of the reported date.
The types of assets and liabilities included in Level 2 are typically either comparable to actively traded securities or contracts, such as treasury securities with pricing interpolated from recent trades of similar securities, or priced with models using highly observable inputs, such as commodity options priced using observable forward prices and volatilities.
Level 3 — Significant inputs to pricing have little or no observability as of the reporting date.
The types of assets and liabilities included in Level 3 are those with inputs requiring significant management judgment or estimation, such as the complex and subjective models and forecasts used to determine the fair value of FTRs.
Xcel Energy continuously monitors the creditworthiness of the counterparties to its commodity derivative contracts and assesses each counterparty’s ability to perform on the transactions set forth in the contracts.
Given this assessment, as well as an assessment of the impact of Xcel Energy’s own credit risk when determining the fair value of commodity derivative liabilities, the impact of considering credit risk was immaterial to the fair value of commodity derivative assets and liabilities presented in the consolidated balance sheets.
The following tables present, for each of these hierarchy levels, Xcel Energy’s assets and liabilities that are measured at fair value on a recurring basis:
