2. Summary of Significant Accounting Policies

New Accounting Pronouncements Not Yet Adopted

Revenue Recognition

In May 2014, the FASB issued guidance codified in ASC 606, “Revenue Recognition - Revenue from Contracts with Customers” (“ASC 606”), which amends the guidance in the former ASC 605, “Revenue Recognition”. ASC 606 is effective for annual periods beginning after December 15, 2016, and interim periods within that reporting period for a public company. The Company may elect either a full retrospective transition method, which requires the restatement of all periods presented, or a modified retrospective transition method, which requires a cumulative effect recognized as of the date of initial application to be used in transition. In August 2015, the FASB delayed the effective date by one year to annual periods beginning after December 15, 2017, and interim periods within that reporting period for a public company. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. Accordingly, the updated standard is effective for the Company as of April 1, 2018 and the Company does not plan to early adopt. The Company is currently in the process of determining whether it will utilize the full or modified retrospective method of adoption allowed by the new standard.

Due to the impact the new standard may have on the Company’s business processes, systems, and controls, a project team has been formed to evaluate and guide the implementation process. To date, the Company has performed a preliminary assessment of key customer contracts and is in the process of comparing historical accounting policies and practices to the new standard, including (i) assessing the current net-of-core value revenue recognition policy, and whether the performance obligation(s) related to the sale of its products will include both the core and unit value; (ii) the assessment of potential variable consideration including the accounting for return rights, the core exchange program, warranty and various allowances provided to its customers; (iii) the classification of assets and liabilities related to core assets and liabilities and customer allowances, and (iv) principal versus agent considerations as amended through Accounting Standards Update (“ASU”) 2016-08, “Principal Versus Agent Considerations (Reporting Revenue Gross Versus Net)”. The Company continues to evaluate the impact ASC 606, related amendments and interpretive guidance will have on its consolidated financial statements.

Financial Instruments

In January 2016, the FASB issued guidance that addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. A reporting entity should apply the new guidance by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The Company is currently evaluating the impact of the provisions of this guidance to its consolidated financial statements.

Leases

In February 2016, the FASB issued new guidance that requires balance sheet recognition of a right-of-use asset and lease liability by lessees for operating leases. The new guidance also requires new disclosures providing additional qualitative and quantitative information about the amounts recorded in the financial statements. The new guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The new guidance requires a modified retrospective approach with optional practical expedients. The Company will adopt this guidance in the first quarter of fiscal 2020. The Company is currently evaluating the impact the provisions of this guidance will have on its consolidated financial statements, but expects that it will result in a significant increase to its long-term assets and liabilities on the consolidated balance sheets.

Business Combinations

In January 2017, the FASB issued guidance which clarifies the definition of a business to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The new guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. A reporting entity should apply the amendment prospectively. The Company is currently evaluating the impact the provisions of this guidance will have on its consolidated financial statements.

Goodwill Impairment

In January 2017, the FASB issued guidance which simplifies the test for goodwill impairment. This standard eliminates Step 2 from the goodwill impairment test, instead requiring an entity to recognize a goodwill impairment charge for the amount by which the goodwill carrying amount exceeds the reporting unit’s fair value. This guidance is effective for interim and annual goodwill impairment tests in fiscal years beginning after December 15, 2019 with early adoption permitted. This guidance must be applied on a prospective basis. The Company is currently evaluating the impact the provisions of this guidance will have on its consolidated financial statements.

Modifications to Share-Based Payment Awards

In May 2017, the FASB issued guidance to provide clarity and reduce (i) the diversity in practice and (ii) the cost and complexity when applying the accounting guidance for equity-based compensation to a change to the terms or conditions of a share-based payment award. This update provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. This guidance is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017 with early adoption permitted. This guidance should be applied prospectively to an award modified on or after that adoption date. The Company is currently evaluating the impact the provisions of this guidance will have on its consolidated financial statements.

New Accounting Pronouncements Recently Adopted

Share-based Compensation

In March 2016, the FASB issued guidance that simplifies several aspects of the accounting for share-based payment transactions and states that, among other things, all excess tax benefits and tax deficiencies should be recognized as income tax expense or benefit in the income statement and an entity can make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures when they occur. The new guidance is effective for interim and annual reporting periods beginning after December 15, 2016 with early adoption permitted. The Company early adopted this guidance effective April 1, 2016 which resulted in a cumulative-effect adjustment of $892,000 through retained earnings and current deferred tax assets to record excess tax benefits not previously recognized. The Company has also elected to account for forfeitures as they occur using the modified retrospective approach which did not have any material impact on its consolidated balance sheets. In addition, the Company is now required to present excess tax benefits as an operating activity (combined with other income tax cash flows) on the statements of cash flows rather than as a financing activity and has elected to adopt this change prospectively.

Extraordinary Items

In January 2015, the FASB issued guidance that simplifies income statement presentation by eliminating the concept of extraordinary items. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. A reporting entity may apply the amendments prospectively or retrospectively to all prior periods presented in the financial statements. Early adoption is permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. There was no impact on the Company’s consolidated financial statements from the adoption of this guidance.

Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern

In August 2014, the FASB issued guidance which requires an entity to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued (or available to be issued). If conditions or events raise substantial doubt that is not alleviated, an entity should disclose that there is substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued (or available to be issued), along with the principal conditions or events that raise substantial doubt, management’s evaluation of the significance of those conditions or events in relation to the entity’s ability to meet its obligations and management’s plans that are intended to mitigate those conditions. The new guidance is effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. There was no impact on the Company’s consolidated financial statements from the adoption of this guidance.

Inventory

In July 2015, the FASB issued guidance that requires an entity to measure inventory at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. Subsequent measurement is unchanged for inventory measured using LIFO or the retail inventory method. The amendments in this update are effective for financial statements issued for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The amendments in this update should be applied prospectively with earlier application permitted as of the beginning of an interim or annual reporting period. The Company early adopted this guidance as of the beginning of the fourth quarter of fiscal 2017. There was no material impact on the Company’s consolidated financial statements as a result of the adoption of this guidance.

Statement of Cash Flows

In August 2016, the FASB issued guidance which adds and/or clarifies guidance on the classification of certain cash receipts and payments in the statement of cash flows. The new guidance is intended to reduce diversity in practice in how certain transactions are presented and classified in the statement of cash flows. The new guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years; early adoption is permitted. The Company early adopted this guidance during fiscal 2017. There was no impact on the Company’s consolidated statements of cash flows as a result of the adoption of this guidance.

Income Taxes

In November 2015, the FASB issued guidance that requires deferred tax liabilities and assets to be classified as noncurrent in the consolidated balance sheet. The guidance is effective for fiscal years beginning after December 15, 2016 including interim periods within those fiscal years with early adoption permitted. A reporting entity should apply the amendment prospectively or retrospectively. The Company early adopted this guidance effective March 31, 2017, which resulted in the classification of all deferred tax assets and deferred tax liabilities as noncurrent in its consolidated balance sheets. As the Company elected to apply this guidance retrospectively, prior periods were reclassified as discussed below under the caption “Reclassification of Prior Period Balances”.

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of Motorcar Parts of America, Inc. and its wholly owned subsidiaries. All significant inter-company accounts and transactions have been eliminated.

Reclassification of Prior Period Balances

The Company retrospectively adopted the newly issued accounting guidance that required deferred tax assets and liabilities to be classified as noncurrent in the consolidated balance sheets, and resulted in the reclassification of (i) $33,247,000 of current deferred income tax assets to long-term deferred income tax assets, (ii) $14,315,000 of long-term deferred income tax liabilities to long-term deferred income tax assets, and (iii) $196,000 of current deferred income tax liabilities from other current liabilities to long-term deferred income tax liabilities in the previously reported consolidated balance sheet at March 31, 2016.

Cash and Cash Equivalents

Cash primarily consists of cash on hand and bank deposits. Cash equivalents consist of money market funds. The Company considers all highly liquid investments purchased with an original or remaining maturity of less than three months at the date of purchase to be cash equivalents. Cash and cash equivalents are maintained with various financial institutions.

Accounts Receivable

The allowance for doubtful accounts is developed based upon several factors including customer credit quality, historical write-off experience and any known specific issues or disputes which exist as of the balance sheet date. Accounts receivable are written off only when all collection attempts have failed. The Company does not require collateral for accounts receivable.

The Company has receivable discount programs that have been established with certain major customers and their respective banks. Under these programs, the Company has the option to sell those customers’ receivables to those banks at a discount to be agreed upon at the time the receivables are sold. Once the customer chooses which outstanding invoices are going to be made available for discounting, the Company can accept or decline the bundle of invoices provided. The receivable discount programs are non-recourse, and funds cannot be reclaimed by the customer or its bank after the related invoices have been discounted.

Inventory

Non-core Inventory

Non-core inventory is comprised of (i) non-core raw materials, (ii) the non-core value of work in process, (iii) the non-core value of remanufactured finished goods, and (iv) purchased finished goods. Used Cores, the Used Core value of work in process and the Remanufactured Core portion of finished goods are classified as long-term core inventory as described below under the caption “Long-term Core Inventory.” Used Cores are a source of raw materials used in the manufacturing of the Company’s products.

Non-core inventory is stated at the lower of cost or net realizable value. The cost of non-core remanufactured inventory approximates average historical purchase prices paid for raw materials, and is based upon the direct costs of material and an allocation of labor and variable and fixed overhead costs. The cost of purchased finished goods inventory approximates average historical purchase prices paid, and an allocation of fixed overhead costs. The cost of non-core inventory is evaluated at least quarterly during the fiscal year and adjusted as necessary to reflect current lower of cost or net realizable value levels. These adjustments are determined for individual items of inventory within each of the following classifications of non-core inventory as follows:

•

Non-core raw materials are recorded at average cost, which is based on the actual purchase price of raw materials on hand. The average cost is updated quarterly. This average cost is used in the inventory costing process and is the basis for allocation of materials to finished goods during the production process.

•

Non-core work in process is in various stages of production and is valued at the average cost of materials issued to open work orders. Historically, non-core work in process inventory has not been material compared to the total non-core inventory balance.

•

The cost of remanufactured finished goods includes the average cost of non-core raw materials and allocations of labor and variable and fixed overhead costs. The allocations of labor and variable and fixed overhead costs are determined based on the average actual use of the production facilities over the prior twelve months which approximates normal capacity. This method prevents the distortion in allocated labor and overhead costs that would occur during short periods of abnormally low or high production. In addition, the Company excludes certain unallocated overhead such as severance costs, duplicative facility overhead costs, start-up costs, training, and spoilage from the calculation and expenses these unallocated overhead as period costs.

The Company records an allowance for potentially excess and obsolete inventory based upon recent sales history, the quantity of inventory on-hand, and a forecast of potential use of the inventory. The Company periodically reviews inventory to identify excess quantities and part numbers that are experiencing a reduction in demand. Any part numbers with quantities identified during this process are reserved for at rates based upon management’s judgment, historical rates, and consideration of possible scrap and liquidation values which may be as high as 100% of cost if no liquidation market exists for the part.

The quantity thresholds and reserve rates are subjective and are based on management’s judgment and knowledge of current and projected industry demand. The reserve estimates may, therefore, be revised if there are changes in the overall market for the Company’s products or market changes that in management’s judgment, impact its ability to sell or liquidate potentially excess or obsolete inventory. The Company had recorded reserves of $4,125,000 and $3,626,000 for excess and obsolete inventory at March 31, 2017 and 2016, respectively. This increase in excess and obsolete inventory was due to higher inventory levels to support the Company’s growth.

The Company records vendor discounts as a reduction of inventories that are recognized as a reduction to cost of sales as the inventories are sold.

Inventory Unreturned

Inventory unreturned represents the Company’s estimate, based on historical data and prospective information provided directly by the customer, of finished goods shipped to customers that the Company expects to be returned, under its general right of return policy, after the balance sheet date. Because all cores are classified separately as long-term assets, the inventory unreturned balance includes only the added unit value of a finished good. The return rate is calculated based on expected returns within the normal operating cycle of one year. As such, the related amounts are classified in current assets.

Inventory unreturned is valued in the same manner as the Company’s finished goods inventory.

Long-term Core Inventory

Long-term core inventory consists of:

•

Used Cores purchased from core brokers and held in inventory at the Company’s facilities,

•

Used Cores returned by the Company’s customers and held in inventory at the Company’s facilities,

•

Used Cores returned by end-users to customers but not yet returned to the Company are classified as Remanufactured Cores until they are physically received by the Company,

•

Remanufactured Cores held in finished goods inventory at the Company’s facilities; and

•

Remanufactured Cores held at customer locations as a part of the finished goods sold to the customer. For these Remanufactured Cores, the Company expects the finished good containing the Remanufactured Core to be returned under the Company’s general right of return policy or a similar Used Core to be returned to the Company by the customer, in each case, for credit.

Long-term core inventory is recorded at average historical purchase prices determined based on actual purchases of inventory on hand. The cost and net realizable value of Used Cores for which sufficient recent purchases have occurred are deemed the same as the purchase price for purchases that are made in arm’s length transactions.

Long-term core inventory recorded at average historical purchase prices is primarily made up of Used Cores for newer products related to more recent automobile models or products for which there is a less liquid market. The Company purchases these Used Cores from core brokers to supplement the yield from returned cores and the under return by consumers.

Used Cores obtained in core broker transactions are valued based on average purchase price. The average purchase price of Used Cores for more recent automobile models is retained as the cost for these Used Cores in subsequent periods even as the source of these Used Cores shifts to the core exchange program.

Long-term core inventory is recorded at the lower of cost or net realizable value. In the absence of sufficient recent purchases the Company uses the net selling price its customers have agreed to pay for Used Cores that are not returned to the Company under the Company’s core exchange program to assess whether Used Core cost exceeds Used Core net realizable value on a customer by customer basis.

The Company classifies all of its core inventories as long-term assets. The determination of the long-term classification is based on its view that the value of the cores is not consumed or realized in cash during the Company’s normal operating cycle, which is one year for most of the cores recorded in inventory. According to guidance provided under the FASB ASC, current assets are defined as “assets or resources commonly identified as those which are reasonably expected to be realized in cash or sold or consumed during the normal operating cycle of the business.” The Company does not believe that the economic value of core inventories, which the Company classifies as long-term, is consumed because the credits issued upon the return of Used Cores offset the amounts invoiced when the Remanufactured Cores included in finished goods were sold. The Company does not expect the economic value of core inventories to be consumed, and thus the Company does not expect to realize cash, until its relationship with a customer ends, a possibility that the Company considers remote based on existing long-term customer agreements and historical experience.

However, historically for certain finished goods sold, the Company’s customer will not send the Company a Used Core to obtain the credit the Company offers under its core exchange program. Therefore, based on the Company’s historical estimate, the Company derecognizes the core value for these finished goods as the Company believes the economic value has been consumed and the Company has realized cash.

For these reasons, the Company concluded that it is more appropriate to classify core inventory as long-term assets.

Long-term Core Inventory Deposit

The long-term core inventory deposit represents the cost of Remanufactured Cores the Company has purchased from customers, which are held by the customers and remain on the customers’ premises. The costs of these Remanufactured Cores were established at the time of the transaction based on the then current cost, determined as noted under the caption “Long-term Core Inventory”. The selling value of these Remanufactured Cores was established based on agreed upon amounts with these customers. The Company expects to realize the selling value and the related cost of these Remanufactured Cores when its relationship with a customer ends, a possibility that the Company considers remote based on existing long-term customer agreements and historical experience.

Customer Finished Goods Returns Accrual

The customer finished goods returns accrual represents the Company’s estimate of its exposure to customer returns, including warranty returns, under its general right of return policy to allow customers to return items that their end user customers have returned to them and from time to time, stock adjustment returns when the customers’ inventory of certain product lines exceeds the anticipated sales to end-user customers. The customer finished goods returns accrual represents the non-core sales value of the estimated returns and is classified as a current liability due to the expectation that these returns will occur within the normal operating cycle of one year.

Accrued Core Payment

The accrued core payment represents the full Remanufactured Core sales price of Remanufactured Cores the Company has purchased from its customers, which are held by these customers and remain on their premises. At the same time, the Company records the long-term core inventory for the Remanufactured Cores purchased at its cost, determined as noted under the caption “Long-term Core Inventory”. The difference between the full Remanufactured Core sales price of Remanufactured Cores and its related cost is treated as sales allowance reducing revenue when the purchases are made.

The repayments for these Remanufactured Core inventory purchases are made through the issuance of credits against that customer’s receivables either on a one time basis or over an agreed-upon period. The accrued core payment is recorded as a current and noncurrent liability in the consolidated balance sheets based on whether repayments will occur within the normal operating cycle of one year.

Income Taxes

The Company accounts for income taxes using the liability method, which measures deferred income taxes by applying enacted statutory rates in effect at the balance sheet date to the differences between the tax basis of assets and liabilities and their reported amounts in the financial statements. The resulting asset or liability is adjusted to reflect changes in the tax laws as they occur. A valuation allowance is provided to reduce deferred tax assets when it is more likely than not that a portion of the deferred tax asset will not be realized.

The primary components of the Company’s income tax provision are (i) the current liability or refund due for federal, state and foreign income taxes and (ii) the change in the amount of the net deferred income tax asset, including the effect of any change in the valuation allowance.

Realization of deferred tax assets is dependent upon the Company’s ability to generate sufficient future taxable income. The Company reviews its deferred tax assets on a jurisdiction by jurisdiction basis to determine whether it is more likely than not that the deferred tax assets will be realized. The Company believes that it is more likely than not that future taxable income will be sufficient to realize the recorded deferred tax assets. In evaluating this ability, the Company considers long-term agreements with each of its major customers and the Company periodically compares its forecasts to actual results. Although there can be no assurance that the forecasted results will be achieved, the history of income in all jurisdictions provides sufficient positive evidence that no valuation allowance is needed.

Plant and Equipment

Plant and equipment are stated at cost, less accumulated depreciation. The cost of additions and improvements are capitalized, while maintenance and repairs are charged to expense when incurred. Depreciation is provided on a straight-line basis in amounts sufficient to relate the cost of depreciable assets to operations over their estimated service lives. Machinery and equipment are depreciated over a range from five to ten years. Office equipment and fixtures are depreciated over a range from three to ten years. Leasehold improvements are depreciated over the lives of the respective leases or the service lives of the leasehold improvements, whichever is shorter. Depreciation of assets recorded under capital leases is included in depreciation expense.

Intangible Assets

The Company’s intangible assets other than goodwill are finite–lived and amortized on a straight-line basis over their respective useful lives. Finite-lived intangible assets are analyzed for impairment when and if indicators of impairment exist. As of March 31, 2017, the Company’s intangible assets, net of amortization, were $3,993,000 and there were no indicators of impairment.

Goodwill

The Company evaluates goodwill for impairment at least annually during the fourth quarter of each fiscal year or more frequently when an event occurs or circumstances change that indicate the carrying value may not be recoverable. The Company has concluded that there is one reporting unit and therefore, tests goodwill for impairment at the entity level. In testing for goodwill impairment, the Company may elect to utilize a qualitative assessment to evaluate whether it is more likely than not that the fair value of the reporting unit is less than its carrying amount. If the Company’s qualitative assessment indicates that goodwill impairment is more likely than not, a two-step impairment test is performed. The Company tests goodwill for impairment under the two-step impairment test by first comparing the carrying value of net assets to the fair value of the reporting unit. If the fair value of the reporting unit exceeds the carrying value, goodwill is not considered impaired and no further testing is required. If the carrying value of the reporting unit exceeds the fair value, goodwill is potentially impaired and the second step of the impairment test must be performed. In the second step, the Company would compare the implied fair value of the goodwill to its carrying value to determine the amount of the impairment loss, if any. The Company completed the required annual testing of goodwill for impairment during the fourth quarter of the year ended March 31, 2017, and determined through the qualitative assessment that its goodwill of $2,551,000 is not impaired.

Debt Issuance Costs

Debt issuance costs include fees and costs incurred to obtain financing. Debt issuance costs related to the Company’s term loans are presented in the balance sheet as a direct deduction from the carrying amount of the term loans. Debt issuance costs related to the Company’s revolving loan are presented in prepaid expenses and other current assets in the accompanying consolidated balance sheets, regardless of whether or not there are any outstanding borrowings under the revolving loan. These fees and costs are amortized using the straight-line method, which approximates the effective interest rate method, over the terms of the related loans and are included in interest expense in the Company’s consolidated statements of income.

Foreign Currency Translation

For financial reporting purposes, the functional currency of the foreign subsidiaries is the local currency. The assets and liabilities of foreign operations for which the local currency is the functional currency are translated into the U.S. dollar at the exchange rate in effect at the balance sheet date, while revenues and expenses are translated at average exchange rates during the year. The accumulated foreign currency translation adjustment is presented as a component of comprehensive income or loss in the consolidated statements of shareholders’ equity.

Revenue Recognition

The Company recognizes revenue when performance by the Company is complete and all of the following criteria have been met:

•

Persuasive evidence of an arrangement exists,

•

Delivery has occurred or services have been rendered,

•

The seller’s price to the buyer is fixed or determinable, and

•

Collectability is reasonably assured.

For products shipped free-on-board (“FOB”) shipping point, revenue is recognized on the date of shipment. For products shipped FOB destination, revenues are recognized on the estimated or actual date of delivery. The Company includes shipping and handling charges in its gross invoice price to customers and classifies the total amount as revenue. Shipping and handling costs are recorded as cost of sales.

The price of a finished remanufactured product sold to customers is generally comprised of separately invoiced amounts for the Remanufactured Core included in the product (“Remanufactured Core value”) and for the value added by remanufacturing (“unit value”). Unit value revenue is recorded based on the Company’s price list, net of applicable discounts and allowances. The Company allows customers to return slow moving and other inventory. The Company provides for such returns of inventory by reducing revenue and cost of sales for the unit value of goods sold that are expected to be returned based on a historical return analysis and information obtained from customers about current stock levels as further described under the captions “Customer Finished Goods Returns Accrual” and “Inventory Unreturned”.

The Company accounts for revenues and cost of sales on a net-of-core-value basis. The Company has determined that its business practices and contractual arrangements result in a significant portion of the Remanufactured Cores sold being replaced by similar Used Cores sent back for credit by customers under the Company’s core exchange program. Accordingly, the Company excludes the value of Remanufactured Cores from revenue.

When the Company ships a product, it recognizes an obligation to accept a similar Used Core sent back under the core exchange program by recording a contra receivable account based upon the Remanufactured Core price agreed upon by the Company and its customer. Upon receipt of a Used Core, the Company grants the customer a credit based on the Remanufactured Core price billed and restores the Used Core to on-hand inventory.

When the Company ships a product, it invoices certain customers for the Remanufactured Core portion of the product at full Remanufactured Core sales price. For these Remanufactured Cores, the Company recognizes core revenue based upon an estimate of the rate at which the Company’s customers will pay cash for Remanufactured Cores in lieu of sending back similar Used Cores for credits under the Company’s core exchange program.

In addition, the Company recognizes revenue related to Remanufactured Cores originally sold at a nominal price and not expected to be replaced by a similar Used Core under the core exchange program. Unlike the full price Remanufactured Cores, the Company only recognizes revenue from nominally priced Remanufactured Cores not expected to be replaced by a similar Used Core sent back under the core exchange program when the Company believes it has met all of the following criteria:

•

The Company has a signed agreement with the customer covering the nominally priced Remanufactured Cores not expected to be replaced by a similar Used Core sent back under the core exchange program. This agreement must specify the number of Remanufactured Cores its customer will pay cash for in lieu of sending back a similar Used Core and the basis on which the nominally priced Remanufactured Cores are to be valued (normally the average price per Remanufactured Core stipulated in the agreement).

•

The contractual date for reconciling the Company’s records and customer’s records of the number of nominally priced Remanufactured Cores not expected to be replaced by a similar Used Core sent back under the core exchange program must be in the current or a prior period.

•

The reconciliation of the nominally priced Remanufactured Cores must be completed and agreed to by the customer.

•

The amount must be billed to the customer.

Marketing Allowances

The Company records the cost of all marketing allowances provided to its customers. Such allowances include sales incentives and concessions. Voluntary marketing allowances related to a single exchange of product are recorded as a reduction of revenues at the time the related revenues are recorded or when such incentives are offered. Other marketing allowances, which may only be applied against future purchases, are recorded as a reduction to revenues in accordance with a schedule set forth in the relevant contract. Sales incentive amounts are recorded based on the value of the incentive provided. See Note 14 for a description of all marketing allowances.

Advertising Costs

The Company expenses all advertising costs as incurred. Advertising expenses for the years ended March 31, 2017, 2016 and 2015 were $525,000, $474,000 and $224,000, respectively.

Net Income Per Share

Basic net income per share is computed by dividing net income by the weighted average number of shares of common stock outstanding during the period. Diluted net income per share includes the effect, if any, from the potential exercise or conversion of securities, such as stock options and warrants, which would result in the issuance of incremental shares of common stock.

The following presents a reconciliation of basic and diluted net income per share.

	Years Ended March 31,
	2017		2016		2015
Net income	$	37,573,000	$	10,563,000	$	11,453,000
Basic shares		18,608,812		18,233,163		16,734,539
Effect of dilutive stock options and warrants		809,894		832,930		871,401
Diluted shares		19,418,706		19,066,093		17,605,940
Net income per share:
Basic net income per share	$	2.02	$	0.58	$	0.68

Diluted net income per share	$	1.93	$	0.55	$	0.65

The effect of dilutive options and warrants excludes (i) 293,239 shares subject to options with exercise prices ranging from $28.68 to $34.17 per share for the year ended March 31, 2017 and (ii) 1,100 shares subject to options with an exercise price of $34.17 per share for the year ended March 31, 2016, which were anti-dilutive. There were no anti-dilutive options or warrants for the year ended March 31, 2015.

Use of Estimates

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. On an on-going basis, the Company evaluates its estimates, including those related to the carrying amount of plant and equipment; valuation of acquisition-related intangible assets including goodwill, impairment of long-lived assets, valuation and return allowances for receivables, inventories, and deferred income taxes; accrued liabilities, warrant liability, share-based compensation, and litigation and disputes.

The Company uses significant estimates in the calculation of sales returns. These estimates are based on the Company’s historical return rates and an evaluation of estimated sales returns from specific customers.

The Company uses significant estimates in the calculation of the lower of cost or net realizable value of long-term core inventory.

The Company’s calculation of inventory reserves involves significant estimates. The basis for the inventory reserve is a comparison of inventory on hand to historical production usage or sales volumes.

The Company uses significant estimates in the calculation of its income tax provision or benefit by using forecasts to estimate whether it will have sufficient future taxable income to realize its deferred tax assets. There can be no assurances that the Company’s taxable income will be sufficient to realize such deferred tax assets.

The Company uses significant estimates in the ongoing calculation of potential liabilities from uncertain tax positions that are more likely than not to occur.

A change in the assumptions used in the estimates for sales returns, inventory reserves and income taxes could result in a difference in the related amounts recorded in the Company’s consolidated financial statements.

The carrying amounts of cash, short-term investments, accounts receivable, accounts payable and accrued liabilities approximate their fair value due to the short-term nature of these instruments. The carrying amounts of the revolving loan, term loan and other long-term liabilities approximate their fair value based on current rates for instruments with similar characteristics.

Share-Based Payments

In accounting for share-based compensation awards, the Company follows the accounting guidance for equity-based compensation, which requires that the Company measure the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. The cost associated with stock options is estimated using the Black-Scholes option-pricing model. The cost associated with restricted stock units is measured based on the number of shares granted and the closing price of the Company’s common stock on the grant date, subject to continued employment. The cost of equity instruments is recognized in the consolidated statements of income on a straight-line basis over the period during which an employee is required to provide service in exchange for the award.

The Black-Scholes option-pricing model requires the input of subjective assumptions including the expected volatility of the underlying stock and the expected holding period of the option. These subjective assumptions are based on both historical and other information. Changes in the values assumed and used in the model can materially affect the estimate of fair value.

The following summarizes the Black-Scholes option-pricing model assumptions used to derive the weighted average fair value of the stock options granted during the periods noted.

Credit Risk

The majority of the Company’s sales are to leading automotive aftermarket parts suppliers. Management believes the credit risk with respect to trade accounts receivable is limited due to the Company’s credit evaluation process and the nature of its customers. However, should the Company’s customers experience significant cash flow problems, the Company’s financial position and results of operations could be materially and adversely affected, and the maximum amount of loss that would be incurred would be the outstanding receivable balance, Used Cores expected to be returned by customer, and the value of the Remanufactured Cores held at customers’ locations at March 31, 2017.

Deferred Compensation Plan

The Company has a deferred compensation plan for certain members of management. The plan allows participants to defer salary and bonuses. The assets of the plan are held in a trust and are subject to the claims of the Company’s general creditors under federal and state laws in the event of insolvency. Consequently, the trust qualifies as a Rabbi trust for income tax purposes. The plan’s assets consist primarily of mutual funds and are classified as available for sale. The investments are recorded at market value, with any unrealized gain or loss recorded as other comprehensive income or loss in shareholders’ equity. Adjustments to the deferred compensation liability are recorded in operating expenses. The Company did not redeem any of its short-term investments for the payment of deferred compensation liabilities during the years ended March 31, 2017 and 2016. The carrying value of plan assets was $2,140,000 and $1,813,000, and deferred compensation liability was $2,140,000 and $1,813,000 at March 31, 2017 and 2016, respectively. During the years ended March 31, 2017, 2016, and 2015, an expense of $(14,000), $409,000 and $17,000, respectively, was recorded for each year related to the deferred compensation plan.

Comprehensive Income or Loss

The Company’s total comprehensive income or loss consists of net unrealized income or loss from foreign currency translation adjustments and unrealized gains or losses on short-term investments.
