In determining the appropriate amount of revenue to be recognized under FASB Accounting Standards Codification Topic 606, Revenues, (Topic 606) the Company performed the following steps: (i) identified the promised goods or services in the contract; (ii) determined whether the promised goods or services are performance obligations including whether they are distinct in the context of the contract; (iii) measured the transaction price, including the constraint on variable consideration; (iv) allocated the transaction price to the performance obligations; and (v) recognized revenue when (or as) the Company satisfies each performance obligation.

The Company sells durable medical equipment, replacement parts and supplies to customers and recognizes revenue at the point control is transferred through delivery to the customer. Each piece of equipment, part or supply is distinct and separately priced thus they each represent a single performance obligation. The revenue is allocated amongst the performance obligations based upon the relative standalone selling price method, however, items are typically all delivered or supplied together. The customer and, if applicable, the Payors are generally charged at the time that the product is sold, although separate layers of insurance coverage may need to be invoiced before final billings may occur.

The Company also provides sleep study services to customers and recognizes revenue when the results of the sleep study are complete as that is when the performance obligation is met.

The transaction price on both equipment sales and sleep studies is the amount that the Company expects to receive in exchange for the goods and services provided. Due to the nature of the durable medical equipment business, billing adjustments customarily occur during the collections process when explanations of benefits are received by Payors, and as amounts are deferred to secondary Payors or to patient responsibility. As such, we constrain the transaction price for the difference between the gross charge and what we believe we will collect from Payors and from patients. The transaction price therefore is predominantly based on contractual payment rates determined by the Payors. The Company does not generally contract with uninsured customers. We determine our estimates of billing adjustments based upon contractual agreements, our policies and historical experience. While the rates are fixed for the product or service with the customer and the Payors, such amounts typically include co-payments, co-insurance and deductibles, which vary in amounts, from the patient customer. The Company includes in the transaction price only the amount that the Company expects to be entitled, which is substantially all of the Payor billings at contractual rates. The transaction price is initially constrained by the amount of customer co-payments we estimate will not be collected.

Due to the nature of the industry and the reimbursement environment in which the Company operates, certain estimates are required to record net revenue and accounts receivable. Inherent in these estimates is the risk that they will have to be revised or updated as additional information becomes available. Specifically, the complexity of many third-party billing arrangements and the uncertainty of reimbursement amounts for certain services from certain Payors may result in adjustments to amounts originally recorded. Such adjustments are typically identified and recorded at the point of cash application or claim denial. The Company constrains revenue for these estimated adjustments. There were no material changes in estimates recorded in the six months ended December 31, 2020, relating to prior periods.

The payment terms and conditions of customer contracts vary by customer type and the products and services offered.

The Company may provide shipping services prior to the point of delivery and has concluded that the services represent a fulfilment activity and not a performance obligation. Returns and refunds are not accepted on either equipment sales or sleep study services. The Company does not offer warranties to customers in excess of the manufacturer’s warranty. Any taxes due upon sale of the products or services are not recognized as revenue. The Company does not incur contract acquisition costs. The Company does not have any partially or unfilled performance obligations related to contracts with customers. However, during the quarter ended June 30, 2020, the Company applied for and received $4.4 million in advanced payments from the Centers for Medicare and Medicaid Services (CMS) under their Accelerated and Advance Payment Program, which was expanded to increase cash flow to providers of services and suppliers impacted by the COVID-19 pandemic. These advance payments will begin to be recouped against the Company’s future Medicare and Medicaid claims beginning in the fourth quarter of our fiscal year 2021. These amounts are included within deferred revenue on the condensed consolidated balance sheet. The Company has no other contract liabilities as of December 31, 2020 or September 30, 2020.

Included in sales and services revenue are unbilled amounts for which the revenue recognition criteria had been met as of period end but were not yet billed to the Payor. The estimate of net unbilled rental revenue recognized is based on historical trends and estimates of future collectability. As of December 31, 2020 and June 30, 2020, net unbilled sales and services revenue is approximately $0.8 million and $1.2 million, respectively, and is included in accounts receivable.

The Company recognizes revenue from its investment management business at amounts that reflect the consideration to which it expects to be entitled in exchange for providing services to its customer. Investment management revenue primarily consists of fees based on a percentage of assets under management; fees based on the performance of managed assets; and administrative fees. Fees are based on agreements with each investment product and may be terminated at any time by either party subject to the specific terms of each respective agreement.

The Company earns management fees based on the investment management agreement GECM has with GECC. The performance obligation is satisfied over time as the services are rendered, since GECC simultaneously receives and consumes the benefits provided as GECM performs services. Under GECC’s investment management agreement with GECM, the base management fee from GECC is calculated at an annual rate of 1.50% of GECC’s average adjusted gross assets. The base management fee is calculated based on the average value of GECC’s gross assets, excluding cash and cash equivalents, at the end of the two most recently completed calendar quarters, and is recognized over time as the services are provided. Management fees are billed quarterly in arrears.

The Company earns incentive fees based on the investment management agreements GECM has with GECC and separately managed accounts. Where an investment management agreement includes both management fees and incentive fees, the performance obligation is considered to be a single obligation for both fees. Incentive fees are variable consideration associated with the GECC investment management agreement. Incentive fees are recognized based on investment performance during the period, subject to the achievement of minimum return levels or high-water marks, in accordance with the terms of the respective investment management agreements. Incentive fees range from 5.0% to 20.0% of the performance-based metric specified within each agreement. Because of the uncertainty of when incentive fees will be collected due to market conditions and investment performance, incentive fees are fully constrained and not recorded until received and the probability of significant reversal of the fees is eliminated in accordance with the respective investment management agreements. As of December 31, 2020, there is $9.2 million in incentive fees which have been earned per the terms of the investment management agreements but not recognized as they are still subject to the constraints described above.

The Company earns administration fees based on the administration agreement GECM has with GECC whereby GECC reimburses GECM for costs incurred in performing administrative functions for GECC. This revenue is recognized over time as the services are performed. Administrative fees are billed quarterly in arrears, which is consistent with the timing of the delivery of services and reflect agreed upon rates for the services provided. The services are accounted for as a single performance obligation that is a series of distinct services with substantially the same pattern of transfer as the services are provided on a daily basis.

Under FASB Accounting Standards Codification Topic 842, Leases, (Topic 842) rental income from operating leases is recognized on a straight-line basis, based on contractual lease terms with fixed and determinable increases over the non-cancellable term of the related lease when collectability is reasonably assured. The Company leases durable medical equipment to customers for a fixed monthly amount on a month-to-month basis. The contractual length of the lease term varies based on the type of equipment that is rented to the customer, but generally is from 10 to 36-months. In the case of capped rental agreements, title to the equipment transfers to the customer at the end of the contractual rental period. The customer has the right to cancel the lease at any time during the rental period for a subsequent month’s rental and payments are generally billed in advance on a month-to-month basis. Under Topic 842, rental income from operating leases is recognized on a month-to-month basis, based on contractual lease terms when collectability is reasonably assured. Certain customer co-payments are included in revenue when considered probable of payment.

The lease term begins on the date products are delivered to patients and are recorded at amounts estimated to be received under reimbursement arrangements with third-party payors, including Medicare, private payors, and Medicaid. Due to the nature of the industry and the reimbursement environment in which the Company operates, certain estimates are required to record net revenue and accounts receivable at their net realizable values. Inherent in these estimates is the risk that they will have to be revised or updated as additional information becomes available. Specifically, the complexity of many third-party billing arrangements and the uncertainty of reimbursement amounts for certain services from certain Payors may result in adjustments to amounts originally recorded. Such adjustments are typically identified and recorded at the point of cash application or claim denial. There were no material changes in estimates recorded in the six months ended December 31, 2020, relating to prior periods.

Although invoicing typically occurs at the beginning of the monthly rental period, we recognize revenue from rentals on a daily basis. Since rental agreements can commence at any time during a given month, we defer revenue related to the remaining monthly rental period as of period end. Deferred revenue related to rentals was $1.0 million and $1.3 million as of December 31, 2020 and June 30, 2020, respectively.

Included in rental revenue are unbilled amounts for which the revenue recognition criteria had been met as of period end but were not yet billed to the Payor. Net unbilled rental revenue is recognized to the extent payment is probable. As of December 31, 2020 and June 30, 2020, net unbilled rental revenue is approximately $0.5 million and $0.7 million, respectively, and is included in accounts receivable.

Consistent with the leases of durable medical equipment, the Company recognizes rental revenue on a straight-line basis over the non-cancelable term of the lease. Under the terms of the lease, the Company may recover from the tenant certain expenses, including: real estate taxes, insurance and other operating expenses. The recovery of these expenses is recognized in rental income in the accompanying condensed consolidated statements of operations, in the same periods as the expenses are incurred. These expenses recognized in both revenue and expense may fluctuate from period to period based on actual expense amounts.
