The Ministry of Finance issued a Circular regulating the depreciation of maritime infrastructure assets.

According to the Circular, maritime infrastructure assets are determined with original price, remaining value, depreciation according to the provisions of this Circular, including: 1. Ports, buoy terminals; 2. Headquarters, service facilities, warehouses, yards, factories and other auxiliary works in the port area; 3. Traffic information system, communication system and electricity and water system in the port area; 4. Maritime traffic monitoring and coordination system (VTS); 5. Breakwaters, sand protection dykes, diversion embankments, shore protection embankments; 6. Maritime channels, pilot boarding and disembarkation areas, quarantine areas; 7. Transshipment areas, anchorage areas, storm shelters in seaport waters; 8. Other maritime infrastructure assets.

The determination of maritime infrastructure assets is regulated as follows: Assets used independently are determined as one asset. A system consisting of many separate asset components linked together to perform one or several specific functions, if any of them is missing, the whole system cannot operate, then that system is determined as one asset. In case a system is assigned to many asset management agencies, the asset portion assigned to each management agency is one asset.

The above-mentioned maritime infrastructure assets are determined to be fixed assets when they simultaneously satisfy the following two criteria: 1- Have a usage period of 1 (one) year or more; 2- Have an original price of 30 million VND or more.

Maritime infrastructure assets must have asset records established to strictly manage physical objects and values in accordance with the provisions of the law on management and use of public assets and relevant laws. Indicators on original price, depreciation, and residual value of maritime infrastructure assets identified as fixed assets are integers; in case the results of determining these indicators are decimals, they shall be rounded in accordance with the provisions of the law on accounting.

Each maritime infrastructure asset is an accounting entry. Accounting for maritime infrastructure assets must reflect and record complete information on the original cost, depreciation, and residual value of the asset.

The Circular clearly states the List of assets, depreciation time and depreciation rate of maritime infrastructure assets as follows:
