- Definition

This element represents the noncurrent portion of a long-term real estate loan to finance building costs. The funds are disbursed as needed or in accordance with a prearranged plan; generally, a portion of the funds is disbursed at inception and the remainder as construction progresses. The money is repaid on completion of the project (generally one to seven years), usually from the proceeds of a mortgage loan. The rate is normally higher than the prime rate, and there is usually an origination fee. The effective yield on these loans tends to be high, and the lender has a security interest in the real property.

Bryant Street and MRP
Loan guarantee amount	$ 26,000						$ 26,000
Loan guarantee term							48 months
Loan guarantee description							The Company and MRP guaranteed $26 million of the loan in exchange for a 1% lower interest rate. The Company and MRP have a side agreement limiting the Company’s guarantee to its proportionate ownership. The value of the guarantee was calculated at $1.9 million based on the present value of the 1% interest savings over the anticipated 48 month term. This amount is included as part of the Company’s investment basis and is amortized to expense over the 48 months. The Company will evaluate the guarantee liability based upon the success of the project and assuming no payments are made under the guarantee the Company will have a gain for $1.9 million when the loan is paid in full.
