BEIJING - China's top audit office on Monday revealed its own problems, reporting about 24.04 million yuan ($3.89 million) of "flawed funds" in 2012.

An audit on the office showed its 2012 budget, as well as other financial revenues and expenditures, were well run, but certain problems existed, according to the National Audit Office (NAO).

For example, about 3.61 million yuan of spending on computer maintenance and equipment updating was not listed in the budget. Also, a purchasing plan to spend 216,000 yuan to renovate security and fire service systems in office buildings was not carried out.

The audit was carried out from March to April.

The NAO on Monday also published audit results on 57 departments under the central government over how they implemented their 2012 budgets.
