The Company mitigates the concentration of credit risk as it relates to financing arrangements by entering into loan syndications with multiple, reputable financial institutions and diversifying its debt counterparties. The Company also reduces exposure by diversifying its derivatives across multiple counterparties who meet established credit and capital guidelines. </span></div>Concentrations of credit risk may also arise when the Company enters into leases with multiple tenants concentrated in the same industry, or into a significant lease or multiple leases with a single tenant, or tenants are located in the same geographic region, or have similar economic features that would cause their inability to meet contractual obligations, including those to the Company, to be similarly affected. The Company regularly monitors its tenant base to assess potential concentrations of credit risk through financial statement review, tenant management calls, and press releases. Management believes the current credit risk portfolio is reasonably well diversified and does not contain any unusual concentration of credit risk.
