Public institutions implement programs, as set out in laws, with various income sources, such as consignment programs, monopolistic programs, and non-subsidized revenues, in addition to government funds. However, the National Assembly's evaluation of public institutions' final accounts is conducted primarily on programs funded by the government. This naturally limits the effectiveness of the evaluation of final accounts for all programs carried out by public institutions.    

In response, the National Assembly Budget Office (NABO) published the FY 2015 Final Accounts Evaluation for Public Institutions. It includes analyses on overall evaluation on major programs conducted by public institutions and their financial stability, in order to support the National Assembly's final accounts evaluation and inspection of government offices.  

It was found as of June 2016 that debts of 323 public institutions totaled KRW 505 trillion at the end of 2015, which was down KRW 15 trillion from KRW 520 trillion at the end of 2014. The debt ratio declined from 201% to 183%, indicating that financial soundness of public institutions had improved overall. However, the financial soundness of the Korea Development Bank and the Export-Import Bank of Korea has recently deteriorated, as shown in the decline in their BIS ratios and the rise in their non-performing loan ratios. The evaluation showed that some of their functions require systematic improvement. Problems discovered included a lack of objective evaluation criteria for debt servicing capacity of borrowers.

In the report, NABO pointed out that public institutions need to take measures to improve their salary peak system, such as rendering support for job competency improvement, because they have not rigorously implemented job competency improvement programs for those eligible for the system and appropriately managed supernumerary employees. For public firms in the electric power industry, settlement unit prices were much higher than unit costs of power generation. NABO suggested that they disclose electric power charges relating to settlement and enforce the vesting contract early to induce competition among power generators through standard unit costs for power generation. The report also pointed out that K-Water needs to offer more feasible measures to address its debts because its current measures, such as implementing projects for waterfront space development, power generation, and special district development, are not specific enough. NABO suggested that the Korea Tourism Organization accelerate the process of sale of tourist resorts that have made little progress, according to its plan to reestablish its main function of promoting tourism. After evaluation of major programs of public institutions, NABO proposed 25 cases requiring legal, institutional, and policy improvement: 22 cases requiring policy improvement and three cases requiring revision of laws. For instance, the report indicated excessive accumulation of reserves by the National Health Insurance Service and need for improvement of the operational efficiency of SR Co., Ltd, which is an operator of the Suseo high-speed railway.
