Adoption of CPC 47 (IFRS 15)

As of January 1, 2018, the adoption of IFRS 9 (CPC 48) or IFRS 15 (CPC 47)  became mandatory, in effect as of the disclosure of the Annual Financial Statements for 2018. The Company opted to adopt IFRS 15, whose principles are based on the business model that identifies the contract with the client (goods or services) and its respective contractual performance obligations, defining the price of the transaction and recognition of income as of the realization of these obligations (recognition of the Contractual Assets).

The Contractual Assets are calculated on monthly basis as of the future flow of income brought to present value at the Project Rate, which refers to the cost of capital of the asset valued at the time of its acquisition.

Project Cash Flow

Under the accounting method (CPC 47 – Contractual Asset), the efficiencies/inefficiencies generated in the project under construction are recorded as implementation of infrastructure margin. That is, the implementation of infrastructure revenues comprised the implementation margin, calculated by the difference between the Present
Value of the RAP and the Future Value of Implementation Cost in the start-up of operations (see picture above). In other words, the implementation revenues is calculated, over the pre-operational period, as the implementation cost plus the implementation margin, which also includes the interest on the remuneration of the asset in the period, calculated by the Project Rate over the balance of the contractual asset. Therefore, as it relates to the Contractual Asset, the implementation margin impacts the Income Statement of the project.

The revenues from the remuneration are calculated based on the Project Rate levied on the balance of the contractual asset and is recorded solely after the start-up of operations of the project. During the construction period, the interest on the remuneration is included in the Implementation of Infrastructure Revenues and the calculation is performed as described above.

Following the entry into operation, the Contractual Asset is adjusted monthly by inflation (IGP-M or IPCA, according to each concession), calculated by the monetary restatement of future receipts brought to present value by the Project Rate. O&M revenues is a portion of the RAP intended to remunerate the operation and maintenance of the concession’s assets.
