NOTE 9 • MORTGAGES PAYABLE AND LINE OF CREDIT

Most of the properties we own serve as collateral for separate mortgage loans on single properties or groups of properties. The majority of these mortgages payable are non-recourse to us, other than for standard carve-out obligations such as fraud, waste, failure to insure, environmental conditions and failure to pay real estate taxes. Interest rates on mortgages payable range from 2.47% to 7.94%, and the mortgages have varying maturity dates from the current fiscal year through July 1, 2036. As of July 31, 2016, our management believes there are no material defaults or material compliance issues in regard to any mortgages payable.

Of the mortgages payable, including mortgages on properties held for sale, the balances of fixed rate mortgages totalled $635.1 million at July 31, 2016 and $689.3 million at April 30, 2016. The balances of variable rate mortgages totalled $249.2 million and $196.8 million as of July 31, 2016 and April 30, 2016, respectively. We do not utilize derivative financial instruments to mitigate our exposure to changes in market interest rates. Most of the fixed rate mortgages have substantial pre-payment penalties. As of July 31, 2016, the weighted average rate of interest on our mortgage debt was 4.54%, compared to 4.54% on April 30, 2016. The aggregate amount of required future principal payments on mortgages payable as of July 31, 2016, is as follows:

In addition to the individual mortgage loans comprising our $884.4 million of mortgage indebtedness, we also have a revolving, multi-bank line of credit with First International Bank and Trust, Watford City, North Dakota, as lead bank, which had, as of July 31, 2016, lending commitments of $100.0 million. This line of credit is not included in our mortgage indebtedness total. As of July 31, 2016, the line of credit was secured by mortgages on 17 properties. Under the terms of the line of credit, properties may be added and removed from the collateral pool with the agreement of the lenders. Participants in this credit facility as of July 31, 2016 included, in addition to First International Bank, the following financial institutions: The Bank of North Dakota, First Western Bank and Trust, Dacotah Bank, Highland Bank, American State Bank & Trust Company, Town & Country Credit Union, WoodTrust Bank, United Community Bank and United Bankers’ Bank. As of July 31, 2016, the line of credit had an interest rate of 4.75% and a minimum outstanding principal balance requirement of $17.5 million. As of July 31, 2016 and April 30, 2016, we had borrowed $17.5 million, respectively. The line of credit includes covenants and restrictions requiring us to achieve on a fiscal and calendar quarter basis a debt service coverage ratio on borrowing base collateral of 1.25x in the aggregate and 1.00x on individual assets in the collateral pool. We are also required to maintain minimum depository account(s) totaling $6.0 million with First International Bank, of which $1.5 million is to be held in a non-interest bearing account. As of July 31, 2016, we believe we were in compliance with the line of credit’s covenants.
