Revenue Recognition [Abstract]
Revenue Recognition	Revenue Recognition We recognize rental income from operating leases that contain fixed contractual rent changes on a straight line basis over the term of the lease agreements. Certain of our leases with government tenants provide the tenant the right to terminate before the lease expiration date if the legislature or other funding authority does not appropriate the funding necessary for the government tenant to meet its lease obligations; we have determined the fixed non-cancelable lease term of these leases to be the fully executed term of the lease because we believe the occurrence of early terminations to be remote contingencies based on both our historical experience and our assessments of the likelihood of lease cancellation on a separate lease basis. We increased rental income to record revenue on a straight line basis by $1,300 and $149 for the three months ended March 31, 2017 and 2016, respectively. Rents receivable include $22,986 and $21,686 of straight line rent receivables, net of allowance for doubtful accounts of $156 and $155, at March 31, 2017 and December 31, 2016, respectively.

Revenue Recognition

We recognize rental income from operating leases that contain fixed contractual rent changes on a straight line basis over the term of the lease agreements. Certain of our leases with government tenants provide the tenant the right to terminate before the lease expiration date if the legislature or other funding authority does not appropriate the funding necessary for the government tenant to meet its lease obligations; we have determined the fixed non-cancelable lease term of these leases to be the fully executed term of the lease because we believe the occurrence of early terminations to be remote contingencies based on both our historical experience and our assessments of the likelihood of lease cancellation on a separate lease basis.

We increased rental income to record revenue on a straight line basis by $1,300 and $149 for the three months ended March 31, 2017 and 2016, respectively. Rents receivable include $22,986 and $21,686 of straight line rent receivables, net of allowance for doubtful accounts of $156 and $155, at March 31, 2017 and December 31, 2016, respectively.
