“We had another strong year, and have achieved our 12th consecutive quarter of year over year same-store revenue and net operating income growth.” commented H.

Self Administration and Investment Management Transaction:

On September 4, 2014, we entered into a series of transactions, agreements, and amendments to our existing agreements and arrangements (such agreements and amendments hereinafter referred to collectively as the “Self Administration and Investment Management Transaction”), with Strategic Storage Holdings, LLC and our former advisor, Strategic Storage Advisor, LLC (the “Former Advisor”), pursuant to which, effective as of August 31, 2014, we acquired the self storage advisory, asset management, property management and investment management businesses of SSH. The Former Advisor had been responsible for, among other things, managing our affairs on a day-to-day basis and identifying and making acquisitions and investments on our behalf. As a result of the Self Administration and Investment Management Transaction, we are now self-managed, succeed to the advisory, asset management and property management arrangements with two additional REITs, Strategic Storage Trust II, Inc. (“SST II”) and Strategic Storage Growth Trust, Inc. (“SSGT”) (collectively “the Managed REITs”).

NON-GAAP MEASURE – COMPUTATION OF FUNDS FROM OPERATIONS

ADDITIONAL INFORMATION REGARDING NOI, AND FFO

Net Operating Income (“NOI”)

NOI is a non-GAAP measure that we define as net income (loss), computed in accordance with GAAP, generated from properties before corporate general and administrative expenses, asset management fees, interest expense, depreciation, amortization, acquisition expenses, self administration and investment management transaction expenses and other non-property related expenses. We believe that net operating income is useful for investors as it provides a measure of the operating performance of our operating assets because net operating income excludes certain items that are not associated with the operation of the properties. Additionally, we believe that NOI is a widely accepted measure of comparative operating performance in the real estate community. However, our use of the term NOI may not be comparable to that of other real estate companies as they may have different methodologies for computing this amount.

Funds from Operations (“FFO”)

Due to certain unique operating characteristics of real estate companies, the National Association of Real Estate Investment Trusts, or NAREIT, an industry trade group, has promulgated a measure known as funds from operations, or FFO, which we believe to be an appropriate supplemental measure to reflect the operating performance of a REIT. The use of FFO is recommended by the REIT industry as a supplemental performance measure.

We define FFO, a non-GAAP measure, consistent with the standards established by the White Paper on FFO approved by the Board of Governors of NAREIT, as revised in February 2004, or the White Paper. The White Paper defines FFO as net income (loss) computed in accordance with GAAP, excluding gains or losses from sales of property and asset impairment write downs, plus depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures. Adjustments for unconsolidated partnerships and joint ventures are calculated to reflect FFO on the same basis. Our FFO calculation complies with NAREIT’s policy described above.

Presentation of FFO is intended to provide useful information to investors as they review our operating performance and as they compare our operating performance to different REITs, although it should be noted that not all REITs calculate FFO the same way, so comparisons with other REITs may not be meaningful. Furthermore, FFO is not necessarily indicative of cash flow available to fund cash needs and should not be considered as an alternative to net income (loss) or income (loss) from operations as an indication of our performance, as an alternative to cash flows from operations, which is an indication of our liquidity, or indicative of funds available to fund our cash needs including our ability to make distributions to our stockholders. FFO should be reviewed in conjunction with other measurements as an indication of our performance.

For informational purposes, we provide FFO, as adjusted for the exclusion of self administration and investment management transaction expenses, acquisition related costs, amortization of deferred financing costs, realized and unrealized losses on foreign exchange holdings, amortization of fair value adjustments of secured debt and stock based compensation expenses. Although our calculation of FFO, as adjusted differs from NAREIT’s definition of FFO and may not be comparable to that of other REITs and real estate companies, we believe it provides a meaningful supplemental measure of operating performance. We believe that by excluding the noted items, stockholders are presented with an indicator of our operating performance that more closely achieves the objectives of the real estate industry in presenting FFO. FFO, as adjusted should not be considered a replacement of the NAREIT definition of FFO.
