Municipalities may find themselves in a situation when they do not have sufficient financial resources to cover their investment expenses and expenses for the routine maintenance or the development of their territory. They must look for foreign resources, either in the form of refundable or non-refundable funds, which can lead to the indebtedness of municipalities. Whether or not this debt is incurred, can be ascertained through the burden on the total assets of the municipality by external sources, i.e. the level of the coverage of commitments. This paper analyses the above-mentioned issue of all 300 municipalities of the Moravian-Silesian Region in the period 2010-2016. For this purpose, two indicators were selected and analysed - the share of foreign resources in total assets, including subsidy advances, and the share of foreign resources in total assets without subsidy advances. It was assumed that subsidy advances play an important role in the covering of commitments and have a significant impact on how municipalities are assessed in this respect. Based on the analysis, it was found that the coverage of commitments is not a problem for the municipalities of the Moravian-Silesian Region, both with or without the subsidies.
