9. Financial Instruments

The Partnership follows the accounting guidance for financial instruments that establishes a framework for measuring fair value under generally accepted accounting principles and expands disclosure about fair value measurements. This guidance enables the reader of the financial statements to assess the inputs used to develop those measurements by establishing a hierarchy for ranking the quality and reliability of the information used to determine fair values. The statement requires that assets and liabilities carried at fair value be classified and disclosed in one of the following three categories:

Level 1: Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date;

Level 2: Inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly;

Level 3: Inputs are unobservable inputs for the asset or liability.

(a) Fair value of financial instruments

The carrying value of cash and cash equivalents and restricted cash, which are considered Level 1 items as they represent liquid assets with short-term maturities, trade receivables, due to related parties, trade accounts payable and accrued liabilities, approximates their fair value. The fair value of long-term variable rate bank loan approximates the recorded value, due to its variable interest being the LIBOR and due to the fact the lenders have the ability to pass on their funding cost to the Partnership under certain circumstances, which reflects its current assessed risk. The Partnership believes that the terms of its loan are similar to those that could be procured as of June 30, 2019. LIBOR rates are observable at commonly quoted intervals for the full term of the loan and accordingly the bank loan is considered Level 2 item in accordance with the fair value hierarchy.

(b) Concentration of credit risk

Financial instruments which potentially subject the Partnership to significant concentrations of credit risk consist principally of cash and cash equivalents and trade accounts receivable. The Partnership places its cash and cash equivalents, consisting mostly of deposits with a limited number of creditworthy financial institutions rated by qualified rating agencies. Most of the Partnership’s revenues were derived from a few charterers. For the six-month periods ended June 30, 2019 and 2018 there were two customers that each accounted for more than 10% of the Partnership’s revenues from continuing operations for each period. The Partnership does not obtain rights of collateral from its charterers to reduce its credit risk.
