Revenue from Contract with Customer [Abstract] |
Revenue Recognition on Construction Contract and Other Service Revenues | Revenue Recognition on Construction Contract and Other Service Revenues We enter into construction contracts to complete various design and construction services primarily for our United States Government tenants. The revenues and expenses from these services consist primarily of subcontracted costs that are reimbursed to us by our customers along with a fee. These services are an ancillary component of our overall operations, with small operating margins relative to the revenue. We review each contract to determine the performance obligations and allocate the transaction price. We recognize revenue under these contracts as services are performed in an amount that reflects the consideration we expect to receive in exchange for those services. Our performance obligations are satisfied over time as work progresses. Revenue recognition is determined using the input method based on costs incurred as of point in time relative to the total estimated costs at completion to measure progress toward satisfying our performance obligations. We believe incurred costs of work performed best depicts the transfer of control of the services being transferred to the customer. In determining whether the performance obligations of each construction contract should be accounted for separately versus together, we consider numerous factors that may require significant judgment, including: whether the components contracted are substantially the same with the same pattern of transfer; whether the customer could contract with another party to perform construction based on our design project; and whether the customer can elect not to move forward after the design phase of the contract. Most of our contracts have a single performance obligation as the promise to transfer the services is not separately identifiable from other obligations in the contracts and, therefore, are not distinct. Some contracts have multiple performance obligations, most commonly due to having distinct project phases for design and construction for which our customer is making decisions and managing separately. In these cases, we allocate the transaction price between these performance obligations based on the amounts separately set forth in the contracts for such obligations. Contract modifications, such as change orders, are routine for our construction contracts and are generally determined to be additions to the existing performance obligations because they would have been part of the initial performance obligations if they were identified at the initial contract date. We have three main types of compensation arrangements for our construction contracts: guaranteed maximum price (“GMP”); firm fixed price (“FFP”); and cost-plus fee.
• | GMP contracts provide for revenue equal to costs incurred plus a fee equal to a percentage of such costs, up to a maximum contract amount. We generally enter into GMP contracts for projects that are significant in nature based on the size of the project and total fees, and for which the full scope of the project has not been determined as of the contract date. GMP contracts are lower risk to us than FFP contracts since the costs and revenue move proportionately to one another;
• | FFP contracts provide for revenue equal to a fixed fee. These contracts are typically lower in value and scope relative to GMP contracts, and are generally entered into when the scope of the project is well defined. Typically, we assume more risk with FFP contracts than GMP contracts since the revenue is fixed and we could realize losses or less than expected profits if we incur more costs than originally estimated. However, these types of contracts offer the opportunity for additional profits when we complete the work for less than originally estimated. Determining the estimated total costs for contracts under an FFP compensation arrangement may require significant judgment and has a direct effect on our revenue recognition pattern;
• | Cost-plus fee contracts provide for revenue equal to costs incurred plus a fee equal to a percentage of such costs but, unlike GMP contracts, do not have a maximum contract amount. We do not frequently enter into cost-plus fee contracts. Similar to GMP contracts, cost-plus fee contracts are low risk to us since the costs and revenue move proportionately to one another.
Construction contract cost estimates are based on various assumptions, such as performance of subcontractors and cost and availability of materials, to project the outcome of future events over the course of the project. We review and update these estimates regularly as a significant change could affect the profitability of our construction contracts. We recognize adjustments in estimated profit on contracts under the cumulative catch-up method as the modification does not create a new performance obligation. Under this method, the impact of the adjustment on profit recorded to date on a contract is recognized in the period the adjustment is identified. Revenue and profit in future periods are recognized using the adjusted estimate. If at any time the estimate of contract profitability indicates an anticipated loss on the contract, we recognize the total loss in the quarter it is identified. We disaggregate our construction contract and other service revenues by compensation arrangement and by service type as we believe it best depicts the nature, timing and uncertainty of our revenue. The table below reports construction contract and other service revenues by compensation arrangement (in thousands):
| For the Three Months Ended March 31,
| 2018 |  | 2017
Construction contract revenues: |  |  |
GMP | $ | 20,486 |  |  | $ | 6,589 |
FFP | 6,435 |  |  | 6,198 |
Cost-plus fee | 58 |  |  | 17 |
Other | 219 |  |  | 230 |
| $ | 27,198 |  |  | $ | 13,034 |
The table below reports construction contract and other service revenues by service type (in thousands):
| For the Three Months Ended March 31,
| 2018 |  | 2017
Construction contract revenues: |  |  |
Construction | $ | 25,915 |  |  | $ | 10,091 |
Design | 1,064 |  |  | 2,713 |
Other | 219 |  |  | 230 |
| $ | 27,198 |  |  | $ | 13,034 |
We recognized revenue from performance obligations satisfied (or partially satisfied) in previous periods of $309,000 and $146,000 in three months ended March 31, 2018 and 2017, respectively. Our timing of revenue recognition for construction contracts generally differs from the timing of invoicing to customers. We recognize such revenue as we satisfy our performance obligations. Payment terms and conditions vary by contract type. Under most of our contracts, we bill customers monthly, as work progresses, in accordance with the contract terms, with payment due in 30 days, although customers occasionally pay in advance of services being provided. We have determined that our contracts generally do not include a significant financing component. The primary purpose of the timing of our invoicing is for convenience, not to receive financing from our customers or to provide customers with financing. Additionally, the timing of transfer of the services is often at the discretion of the customer. We recognized no impairment losses on construction contracts receivable or unbilled construction revenue in the periods set forth herein. Accounts receivable related to our construction contract services is included in accounts receivable, net on our consolidated balance sheets. The beginning and ending balances of accounts receivable related to our construction contracts were as follows (in thousands):
| For the Three Months Ended March 31,
| 2018 |  | 2017
Beginning balance | $ | 4,577 |  |  | $ | 4,131 |
Ending balance | $ | 4,021 |  |  | $ | 7,376 |
Under most of our contracts, we bill customers one month subsequent to revenue recognition, resulting in contract assets representing unbilled construction revenue. Contract assets, which we refer to herein as construction costs in excess of billings, are included in prepaid expenses and other assets, net reported on our consolidated balance sheets. The beginning and ending balances of our contract assets were as follows (in thousands):
| For the Three Months Ended March 31,
| 2018 |  | 2017
Beginning balance | $ | 4,884 |  |  | $ | 10,350 |
Ending balance | $ | 4,250 |  |  | $ | 4,451 |
Our contract liabilities consist of advance payments from our customers or billings in excess of construction contract revenue recognized. Contract liabilities are included in other liabilities reported on our consolidated balance sheets. Changes in contract liabilities were as follows (in thousands):
| For the Three Months Ended March 31,
| 2018 |  | 2017
Beginning balance | $ | 27,402 |  |  | $ | 32,650 |
Ending balance | $ | 8,279 |  |  | $ | 40,485 |
Revenue recognized included in beginning balance | $ | 19,297 |  |  | $ | 4,199 |
The change in the contract liabilities balance reported above for the three months ended March 31, 2018 was due primarily to our satisfaction of performance obligations during the period on a contract on which we previously received advance payments from a customer. Revenue allocated to the remaining performance obligations under existing contracts as of March 31, 2018 that will be recognized as revenue in future periods was $23.5 million, all of which we expect to recognize during the remainder of 2018. We have no deferred incremental costs incurred to obtain or fulfill our construction contracts or other service revenues.
