Below is a summary of the carrying value of our secured loans as of March 31, 2020 and June 30, 2019:

Secured Loans - Originated: Secured loans include short-term loans, which include a combination of on-demand lines and short-term facilities, and long-term loans that are made to our customers. These loans are fully secured by the customers' assets that include bullion, numismatic, and semi-numismatic material, which are typically held in safekeeping by the Company.  (See Note 13 for further information regarding our secured loans made to related parties.)

Secured Loans - Acquired: Secured loans also include short-term loans, which include a combination of on-demand lines and short term facilities that are purchased from our customers.  The Company acquires a portfolio of their loan receivables at a price that approximates the outstanding balance of each loan in the portfolio, as determined on the effective transaction date.  Each loan in the portfolio is fully secured by the borrowers' assets, which include bullion, numismatic, and semi-numismatic material that are held in safekeeping by the Company. Typically, the seller of the loan portfolio retains the responsibility for the servicing and administration of the loans.

As of March 31, 2020 and June 30, 2019, our secured loans carried weighted-average effective interest rates of 8.2% and 10.2%, respectively, and mature in periods ranging typically from on-demand to one year.

The secured loans that the Company generates with active customers of A-Mark are reflected as an operating activity on the condensed consolidated statements of cash flows. The secured loans that the Company generates with borrowers who are not active customers of A-Mark are reflected as an investing activity on the condensed consolidated statements of cash flows as secured loans receivables, net. For the secured loans that (i) are reflected as an investing activity and have terms that allow the borrowers to increase their loan balance (at the discretion of the Company) based on the excess value of their collateral compared to their aggregate principal balance of loan, and (ii) are repayable on demand or in the short-term, the borrowings and repayments are netted on the condensed consolidated statements of cash flows.

Credit Quality of Secured Loans Receivables and Allowance for Credit Losses

General

The Company's secured loan receivables portfolio comprises loans with similar credit risk profiles, which enables the Company to apply a standard methodology to determine the credit quality for each loan and the allowance for credit losses, if any.

The credit quality of each loan is generally determined by the collateral value assessment, loan-to-value ratio (that is, the principal amount of the loan divided by the estimated value of the collateral) and the type (or class) of secured material.  All loans are fully secured by precious metal bullion or numismatic collateral, which remains in the physical custody of the Company for the duration of the loan.  The term of the loans is generally 180 days. Interest earned on a loan is billed monthly and is typically due and payable within 20 days and, if not paid after all applicable grace periods, is added to the outstanding principal balance, and late fees and default interest rates are assessed.

When an account is in default or if a margin call has not been met on a timely basis, the Company has the right to liquidate the borrower's collateral in order to satisfy the unpaid balance of the outstanding loans, including accrued and unpaid interest.

Class and Credit Quality of Loans

The two classes of secured loan receivables are defined by collateral type: 1) bullion items, and 2) numismatic and semi-numismatic coins.  The loan-to-value ratio varies with the class of loans. Typically, the Company requires a loan-to-value ratio of approximately 75% for bullion and 65% for numismatic collateral.  The reason for the lower loan-to-value ratio for numismatic loans is that, on a percentage basis, more of the value of the numismatic coin relates to its premium value rather than its underlying commodity value.

The Company's secured loans by portfolio class, which align with internal management reporting, are as follows:

Due to the nature of market fluctuations of precious metal commodity prices, the Company monitors the bullion collateral value of each loan on a daily basis, based on spot price of precious metals.  Numismatic collateral values are updated by numismatic specialists when loan term is renewed (typically in 180 days).

Generally, we initiate the margin call process when the outstanding loan balance is in excess of 85% of the current value of the underlying collateral.  In the event that a borrower fails to meet a margin call to reestablish the required loan-to-value ratio, the loan is considered in default.  The collateral material (either bullion or numismatic) underlying such loans is then sold by the Company to satisfy all amounts due under the loan.

Loans with loan-to-value ratios of less than 75% are generally considered to be higher quality loans. Below is summary of aggregate outstanding secured loan balances bifurcated into 1) loans with a loan-to-value ratio of 75% or more and 2) loans with a loan-to-value ratio of less than 75%:

The Company had no loans with a loan-to-value ratio in excess of 100% as of March 31, 2020 or June 30, 2019.

Non-Performing Loans/Impaired Loans

Historically, the Company has not established an allowance for any credit losses because the Company has liquidated the collateral to satisfy the amount due before any loan becomes non-performing or impaired.

Non-performing loans have the highest probability for credit loss. The allowance for credit losses attributable to non-performing loans is based on the most probable source of repayment, which is normally the liquidation of collateral.  Due to the accelerated liquidation terms of the Company's loan portfolio, past due loans are generally liquidated within 90 days of default before a loan becomes non-performing.  In the event a loan were to become non-performing, the Company would determine a reserve to reduce the carrying balance to its estimated net realizable value.  As of March 31, 2020 or June 30, 2019, the Company had no allowance for secured loan losses.

A loan is considered impaired if it is probable, based on current information and events, that the Company will be unable to collect all amounts due according to the contractual terms of the loan. Customer loans are reviewed for impairment and include loans that are past due, non-performing, or in bankruptcy. In the event of an impairment, recognition of interest income would be suspended and the loan would be placed on non-accrual status at the time. Accrual would be resumed, and previously suspended interest income would be recognized, when the loan becomes contractually current and/or collection doubts are removed. Cash receipts on impaired loans are recorded first against the receivable and then to any unrecognized interest income. For the three and nine months ended March 31, 2020 and 2019, the Company incurred no loan impairment costs.
