Subsidiaries

We conduct substantially all of our operations through a subsidiary, Gladstone Commercial Limited Partnership, a Delaware limited partnership, or the Operating Partnership. As we currently own all of the general and limited partnership interests of the Operating Partnership through two of our subsidiaries, GCLP Business Trust I and II, the financial position and results of operations of the Operating Partnership are consolidated with those of the Company.

Gladstone Commercial Lending, LLC, a Delaware limited liability company, or Gladstone Commercial Lending, a subsidiary of ours, was created to conduct all operations related to real estate mortgage loans of the Company. As the Operating Partnership currently owns all of the membership interests of Gladstone Commercial Lending, the financial position and results of operations of Gladstone Commercial Lending are consolidated with those of the Company.

Gladstone Commercial Advisers, Inc., a Delaware corporation, or Commercial Advisers, and a subsidiary of the Company, is a taxable REIT subsidiary, or TRS, which was created to collect any non-qualifying income related to our real estate portfolio. There has been no such income earned to date. Since the Company owns 100% of the voting securities of Commercial Advisers, the financial position and results of operations of Commercial Advisers are consolidated with those of the Company.

GCLP Business Trust I and GCLP Business Trust II, each a subsidiary and business trust of the Company, were formed under the laws of the Commonwealth of Massachusetts on December 28, 2005. We transferred our 99% limited partnership interest in the Operating Partnership to GCLP Business Trust I in exchange for 100 shares of the trust. Gladstone Commercial Partners, LLC transferred its 1% general partnership interest in the Operating Partnership to GCLP Business Trust II in exchange for 100 trust shares.

All further references herein to “we,” “our,” “us” and the “Company” mean Gladstone Commercial Corporation and its consolidated subsidiaries, except where it is made clear that the term means only Gladstone Commercial Corporation.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could materially differ from those estimates.

Real Estate and Lease Intangibles

We record investments in real estate at cost and capitalize improvements and replacements when they extend the useful life or improve the efficiency of the asset. We expense costs of repairs and maintenance as such costs are incurred. We compute depreciation using the straight-line method over the estimated useful life or 39 years for buildings and improvements, 5 to 7 years for equipment and fixtures, and the shorter of the useful life or the remaining lease term for tenant improvements and leasehold interests.

Certain of our acquisitions involve sale-leaseback transactions with newly-originated leases, which we account for as asset acquisitions under Accounting Standards Codification, or ASC, 805, “Business Combinations.” In the case of an asset acquisition, we will capitalize the transaction costs incurred in connection with the acquisition. Other of our acquisitions involve the acquisition of properties that are already being operated as rental property, which we will generally consider to be a business combination under ASC 805. Business combination guidance is generally applicable to us when properties are acquired with leases in place at the time of acquisition. When an acquisition is considered a business combination, ASC 805 requires that the purchase price of real estate be allocated to the acquired tangible assets and liabilities, consisting of land, building, tenant improvements, long-term debt and identified intangible assets and liabilities, typically the value of above-market and below-market leases, the value of in-place leases, the value of unamortized lease origination costs and the value of tenant relationships, based in each case on their fair values. ASC 805 also requires that all expenses related to the acquisition be expensed as incurred, rather than capitalized into the cost of the acquisition.

Management’s estimates of fair value are made using methods similar to those used by independent appraisers (e.g. discounted cash flow analysis). Factors considered by management in its analysis include an estimate of carrying costs during hypothetical expected lease-up periods considering current market conditions and costs to execute similar leases. We also consider information obtained about each property as a result of our pre-acquisition due diligence, marketing and leasing activities in estimating the fair value of the tangible and intangible assets and liabilities acquired. In estimating carrying costs, management also includes real estate taxes, insurance and other operating expenses and estimates of lost rentals at market rates during the hypothetical expected lease-up periods, which primarily range from 9 to 18 months, depending on specific local market conditions. Management also estimates costs to execute similar leases, including leasing commissions, legal and other related expenses to the extent that such costs are not already incurred in connection with a new lease origination as part of the transaction.

We allocate purchase price to the fair value of the tangible assets of an acquired property by valuing the property as if it were vacant. The “as-if-vacant” value is allocated to land, building and tenant improvements based on management’s determination of the relative fair values of these assets. Real estate depreciation expense on these tangible assets was $3.6 million and $7.0 million for the three and six months ended June 30, 2013, respectively, and $2.9 million and $5.6 million for the three and six months ended June 30, 2012, respectively.

Above-market and below-market in-place lease fair values for owned properties are recorded based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases and (ii) management’s estimate of fair market lease rates for the corresponding in-place leases, measured over a period equal to the remaining non-cancelable term of the lease. When determining the non-cancelable term of the lease, we evaluate if fixed-rate renewal options, if any, should be included. The capitalized above-market lease values, included in the accompanying condensed consolidated balance sheets as part of deferred rent receivable, are amortized as a reduction of rental income over the remaining non-cancelable terms of the respective leases. Total amortization related to above-market lease values was $0.1 million for both the three and six months ended June 30, 2013, respectively. Total amortization related to above-market lease values was $0.1 million and $0.2 million for the three and six months ended June 30, 2012, respectively. The capitalized below-market lease values, included in the accompanying condensed consolidated balance sheets as part of deferred rent liability, are amortized as an increase to rental income over the remaining non-cancelable terms of the respective leases. Total amortization related to below-market lease values was $0.1 million and $0.3 million for the three and six months ended June 30, 2013, respectively, and $0.2 million and $0.5 million for the three and six months ended June 30, 2012, respectively.

The total amount of the remaining intangible assets acquired, which consists of in-place lease values, unamortized lease origination costs, and customer relationship intangible values, are allocated based on management’s evaluation of the specific characteristics of each tenant’s lease and our overall relationship with that respective tenant. Characteristics to be considered by management in determining these values include the nature and extent of our existing business relationships with the tenant, growth prospects for developing new business with the tenant, the tenant’s credit quality and our expectations of lease renewals (including those existing under the terms of the lease agreement), among other factors.

The value of in-place leases and lease origination costs are amortized to expense over the remaining term of the respective leases, which generally range from 10 to 15 years. The value of customer relationship intangibles, which is the benefit to us resulting from the likelihood of an existing tenant renewing its lease, are amortized to expense over the remaining term and any anticipated renewal periods in the respective leases, but in no event does the amortization period for intangible assets exceed the remaining depreciable life of the building. Should a tenant terminate its lease, the unamortized portion of the above-market and below-market lease values, in-place lease values, lease origination costs and customer relationship intangibles will be immediately charged to the related income or expense. Total amortization expense related to these intangible assets was $1.6 million and $3.1 million for the three and six months ended June 30, 2013, respectively, and $1.1 million and $2.2 million for the three and six months ended June 30, 2012, respectively.

Impairment

We account for the impairment of real estate, including intangible assets, in accordance with ASC 360-10-35, “Property, Plant, and Equipment,” which requires us to periodically review the carrying value of each property to determine if circumstances indicate impairment of the carrying value of the investment exists or that depreciation periods should be modified. If circumstances indicate the possibility of impairment, we prepare a projection of the undiscounted future cash flows, without interest charges, of the specific property and determine if the carrying value of the investment in such property is recoverable. In performing the analysis, we consider such factors as the tenants’ payment history and financial condition, the likelihood of lease renewal, business conditions in the industry in which the tenants operate and whether there are indications that the fair value of the real estate has decreased. If the carrying amount is more than the aggregate undiscounted future cash flows, we would recognize an impairment loss to the extent the carrying amount exceeds the estimated fair value of the property.

We evaluate our entire portfolio of properties each quarter for any impairment indicators and perform an impairment analysis on those select properties that have an indication of impairment. We performed this evaluation and analysis and concluded that none of our properties were impaired as of June 30, 2013; however, we determined that our property located in South Hadley, Massachusetts may become impaired in the future. The lease on this property expires in January 2014 and we are currently negotiating a potential lease extension with the existing tenant. There is a possibility we would have to impair the property later in 2013 if we do not negotiate a lease extension on this building or find a replacement tenant.

We will continue to monitor our portfolio for any indicators of impairment and there have been no impairments recognized on our real estate assets since inception.

Revenue Recognition

Rental revenue includes rents that each tenant pays in accordance with the terms of its respective lease reported evenly over the non-cancelable term of the lease. Most of our leases contain rental increases at specified intervals. We recognize such revenues on a straight-line basis. Deferred rent receivable in the accompanying condensed consolidated balance sheet includes the cumulative difference between rental revenue, as recorded on a straight-line basis, and rents received from the tenants in accordance with the lease terms, along with the capitalized above-market in-place lease values of certain acquired properties. Accordingly, we determine, in our judgment, to what extent the deferred rent receivable applicable to each specific tenant is collectable. We review deferred rent receivable, as it relates to straight line rents, on a quarterly basis and take into consideration the tenant’s payment history, the financial condition of the tenant, business conditions in the industry in which the tenant operates and economic conditions in the geographic area in which the property is located. In the event that the collectability of deferred rent with respect to any given tenant is in doubt, we record an allowance for uncollectable accounts or record a direct write-off of the specific rent receivable. No such reserves or direct write-offs have been recorded to date.

Tenant recovery revenue includes payments from tenants as reimbursements for franchise taxes, management fees, insurance, and ground lease payments. We recognize tenant recovery revenue in the same periods that we incur the related expenses.

Comprehensive Income

For the three and six months ended June 30, 2013 and 2012, comprehensive income equaled net income; therefore, a separate statement of comprehensive income is not included in the accompanying condensed consolidated financial statements.

The Term Preferred Stock is recorded as liability in accordance with ASC 480, “Distinguishing Liabilities from Equity,” which states that mandatorily redeemable financial instruments should be classified as liabilities and therefore the related dividend payments are treated as a component of interest expense in the statement of operations.
