(1)     Basis of Presentation

The condensed consolidated financial statements included herein have been prepared by Giga-tronics Incorporated (the “Company”), pursuant to the rules and regulations of the Securities and Exchange Commission. The consolidated results of operations for the interim periods shown in this report are not necessarily indicative of results to be expected for the fiscal year. In the opinion of management, the information contained herein reflects all adjustments (consisting of normal recurring entries) necessary to make the consolidated results of operations for the interim periods a fair statement of such operations. For further information, refer to the consolidated financial statements and footnotes thereto, included in the Annual Report on Form 10-K, filed with the Securities and Exchange Commission for the year ended March 28, 2015.

Principles of Consolidation The consolidated financial statements include the accounts of Giga-tronics and its wholly-owned subsidiary. All significant intercompany balances and transactions have been eliminated in consolidation.

Derivatives The Company’s derivatives are valued in accordance with US Generally Accepted Accounting Principles in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standard Codification (“ASC”) Topic 820, Fair Value Measurements and Disclosures. Changes in fair values are reported in earnings as gain or loss on adjustment of derivative liability to fair value. 

New Accounting Standards In July 2015, the FASB issued ASU No, 2015-11,Inventory (Topic 330):“Simplifying the Measurement of Inventory”Inventory”. Topic 330,Inventory, currently requires an entity to measure inventory at the lower of cost or market. Market could be replacement cost, net realizable value, or net realizable value less an approximately normal profit margin. The amendments do not apply to inventory that is measured using last-in, first-out (LIFO) or the retail inventory method. The amendments apply to all other inventory, which includes inventory that is measured using first-in, first-out (FIFO) or average cost. An entity should measure in scope 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 more closely align the measurement of inventory in GAAP with the measurement of inventory in International Financial Reporting Standards. For public business entities, the amendments are effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2016, and interim periods within fiscal years beginning after December 15, 2017. The amendments should be applied prospectively with earlier application permitted as of the beginning of an interim or annual reporting period. The Company is currently evaluating the impact this accounting standard update may have on its financial statements.

(2)     Going Concern and Management’s Plan

The Company incurred net losses of $1.3 million$602,000 for the secondthird quarter of fiscal 2016 and $1.9$2.5 million for the first halfnine months of fiscal 2016, which have contributed to an accumulated deficit of $21.9$22.5 million as of SeptemberDecember 26, 2015.

In the second quarter of fiscal 2016 theThe Company has experienced delays in shipmentsthe development of its legacy Giga-tronics Division testfeatures, orders, and measurement equipment and Microsource radar filter components due to late arriving materials from suppliers. The Company also experienced a delay in shipments for the Giga-tronics Division’s new Advanced Signal Generator product due to technical issues encountered prior to shipment.Generator. These delays in shipments have significantly contributed to a decrease in working capital offrom $3.0 million fromat March 28, 2015, to $1.2 million$443,000 at SeptemberDecember 26, 2015.

Many of the planned second quarter of fiscal 2016 shipments that were delayed, shipped early in the third quarter of fiscal 2016, including three units of the new Advanced Signal Generator product. The new Advanced Signal Generator product has now shipped to several customers, but potential delays in shipping volume quantities, orthe development of features, longer than anticipated sales cycles, or the ability to continue shipments in volume quantities, could significantly contribute to additional future losses. The losses in the first nine months of fiscal 2016 caused working capital restraints, resulting in delayed payments to suppliers. Many suppliers have since halted the shipment of raw materials to the Company until payments for past shipments are received.

The Company has lost, and is seeking to regain its AS9100C Certification that is commonly required in the aircraft manufacturing industry. The Company’s Microsource division sells components used on military aircrafts to two major customers that have the expectation the Company will have a Supplier Quality Management System certified to be AS9100C compliant. The Company has worked with one of the major customers to allow continued shipping and orders during the lapse in certification by allowing the customer to do its own quality inspections prior to the shipment of the Company’s products. The Company is working with the second customer for a similar solution during the lapse in certification. The Company’s Giga-tronics division receives orders from time to time that require a Supplier Quality Management System certified to be AS9100C. If the Company was unable to regain AS9100C certification, the lack of certifications could result in a loss of revenue and have a material adverse effect on results of operations and working capital.

These matters raise substantial doubt as to the ability of the Company to continue as a going concern.

To address this matter,these matters, the Company’s management has taken several actions to provide additional liquidity and reduce costs and expenses going forward. These actions are described in the following paragraphs.

Management will continue to review all aspects of the business in an effort to improve cash flow and reduce costs and expenses, while continuing to invest, to the extent possible, in new product development for future revenue streams.

Management will also continue to seek additional working capital through debt, equity financing or possible product line sales, however there are no assurances that such financings or sales will be available at all, or on terms acceptable to the Company.

The current year loss has had a significant negative impact on the financial condition of the Company and raiseraises substantial doubt about the Company’s ability to continue as a going concern. The Consolidated Financial Statements have been prepared assuming the Company will continue as a going concern and do not include any adjustments that might result if the Company were unable to do so.    

(3)     Revenue Recognition

The Company records revenue when there is persuasive evidence of an arrangement, delivery has occurred, the price is fixed and determinable, and collectability is reasonably assured. This occurs when products are shipped or the customer accepts title transfer. If the arrangement involves acceptance terms, the Company defers revenue until product acceptance is received. The Company limits the amount of revenue recognition for delivered elements to the amount that is not contingent on the future delivery of products or services, future performance obligations or subject to customer-specified return or refund privileges. The Company evaluates each deliverable in an arrangement to determine whether they represent separate units of accounting. On certain large development contracts, revenue is recognized upon achievement of substantive milestones. Determining whether a milestone is substantive is a matter of judgment and that assessment is performed only at the inception of the arrangement. The consideration earned from the achievement of a milestone must meet all of the following for the milestone to be considered substantive:

a. It is commensurate with either of the following:

1. The Company’s performance to achieve the milestone.

2. The enhancement of the value of the delivered item or items as a result of a specific outcome resulting from the Company's performance to achieve the milestone.

b. It relates solely to past performance.

c. It is reasonable relative to all of the deliverables and payment terms (including other potential milestone consideration) within the arrangement.

Milestones are agreed upon with the customer prior to the start of the contract and some milestones will be tied to product shipping while others will be tied to design review. In fiscal 2015 the Company’s Microsource business unit received a $6.5 million order from a major aerospace company for non-recurring engineering services to develop a variant of its high performance fast tuning YIG filters for an aircraft platform and to deliver a limited number of flight-qualified prototype hardware units (the “NRE Order”) which is being accounted for on a milestone basis. The Company considered factors such as estimated completion dates and product acceptance of the order prior to accounting for the NRE Order as milestone revenue. During the three and sixnine month periods ended SeptemberDecember 26, 2015 and September 26,December 27, 2014, revenue recognized on a milestone basis were $18,000$6,000 and $710,000,$716,000, and $1.3$1.6 million and $2.9$4.5 million, respectively.

On certain contracts with several of the Company’s significant customers, the Company receives payments in advance of manufacturing. Advanced payments are recorded as deferred revenue until the revenue recognition criteria described above has been met.

Accounts receivable are stated at their net realizable value. The Company has estimated an allowance for uncollectable accounts based on analysis of specifically identified accounts, outstanding receivables, consideration of the age of those receivables, the Company’s historical collection experience, and adjustments for other factors management believes are necessary based on perceived credit risk.

The Company provides for estimated costs that may be incurred for product warranties at the time of shipment. The Company’s warranty policy generally provides twelve to eighteen months depending on the customer. The estimated cost of warranty coverage is based on the Company’s actual historical experience with its current products or similar products. For new products, the required reserve is based on historical experience of similar products until such time as sufficient historical data has been collected on the new product. Adjustments are made as new information becomes available.

(4)            Inventories

Inventories consisted of the following:

(5)(5)           Earnings/Loss Per Share

Basic earnings (loss) per share (EPS) is calculated by dividing net income or loss allocated to common shareholders by the weighted average common shares outstanding during the period. Net income allocated to common shareholders excludes earnings allocated to certain non-vested restricted stock awards that have non forfeitable dividend rights and therefore are considered participating securities. Diluted EPS reflects the net incremental shares that would be issued if unvested restricted shares became vested and dilutive outstanding stock options were exercised, using the treasury stock method. In the case of a net loss, it is assumed that no incremental shares would be issued because they would be antidilutive.anti-dilutive. In addition, certain options are considered antidilutive because assumed proceeds from exercise price, related tax benefits and average future compensation were greater than the weighted average number of options outstanding multiplied by the average market price during the period. The shares used in per share computations are as follows:

(6)     Share Based Compensation

The Company has established the 2005 Equity Incentive Plan, which provide for the granting of options and restricted stock for up to 2,850,000 shares of common stock at 100% of fair market value at the date of grant, with each grant requiring approval by the Board of Directors of the Company. Options granted generally vest in one or more installments in a four or five year period and must be exercised while the grantee is employed by the Company or within a certain period after termination of employment. Options granted to employees shall not have terms in excess of 10 years from the grant date. Holders of options may be granted stock appreciation rights (SARs), which entitle them to surrender outstanding awards for a cash distribution under certain changes in ownership of the Company, as defined in the stock option plan. As of SeptemberDecember 26, 2015, no SARs have been granted under the option plan. As of SeptemberDecember 26, 2015, the total number of shares of common stock available for issuance is 947,702.958,827. All outstanding options have either a five year or a ten year life. The Company records compensation cost associated with share-based compensation equivalent to the estimated fair value of the awards over the requisite service period. There were no25,000 options granted in the secondthird quarter of fiscal 2016 and for the first halfnine months of fiscal 2016.2016 with weighted average grant day fair value of $1.07. There were 229,50035,000 options granted in the secondthird quarter of fiscal 2015 and for264,500 options were granted in the first halfnine months of fiscal 2015 with weighted average grant date fair values of $1.75$1.23 and $1.68 per share.share, respectively.

In calculating compensation related to stock option grants, the fair value of each stock option is estimated on the date of grant using the Black-Scholes-Merton option-pricing model and the following weighted average assumptions:

(7)(7)     Significant Customer andIndustry Segment Information

The Company has two reportable segments: Giga-tronics Division and Microsource.

Giga-tronics Division produces a broad line of test and measurement equipment used in the development, test and maintenance of wireless communications products and systems, flight navigational equipment, electronic defense systems and automatic testing systems and designs, manufactures, and markets a line of switching devices that link together many specific purpose instruments that comprise automatic test systems. These products are used primarily in the design, production, repair and maintenance of commercial telecommunications, radar, and electronic warfare equipment. Microsource develops and manufactures a broad line of YIG (Yttrium, Iron, Garnet) tuned oscillators, filters and microwave synthesizers, which are used by its customers in operational applications and in manufacturing a wide variety of microwave instruments and devices.

The tables below present information for the three and sixnine month periods ended SeptemberDecember 26, 2015 and SeptemberDecember 27, 2014.

(8) ��     Income Taxes

 
The Company accounts for income taxes using the asset and liability method as codified in Topic 740. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry-forwards.

The Company recorded $2,000did not incur tax expense for the three months ended December 26, 2015 and six months ended September 26, 2015.December 27, 2014. The Company’s tax expense for the three and sixnine months ended SeptemberDecember 26, 2015 and December 27, 2014 was $47,000.$2,000 and $47,000, respectively. The effective tax rate for the three months and six months ended SeptemberDecember 26, 2015 and SeptemberDecember 27, 2014 was 0% primarily due to a valuation allowance recorded against the net deferred tax asset balance. The effective tax rate for the nine months ended December 26, 2015 and December 27, 2014 was 0% and 12%20% primarily due to a valuation allowance recorded against the net deferred tax asset balance. 

As of SeptemberDecember 26, 2015 and March 28, 2015, the Company had recorded $93,000 for unrecognized tax benefits related to uncertain tax positions. The unrecognized tax benefit is netted against the non-current deferred tax asset on the Consolidated Balance Sheet. The Company does not expect the liability for unrecognized tax benefits to change materially within the next 12 months. The Company does have a California Franchise Tax Board audit that is currently in process. The Company is working with the California Franchise Tax Board to resolve all audit issues and does not believe any material taxes, penalties and fees are due. However, as a result of the ongoing examination, the Company recorded an estimated associated tax liability of $45,000 in the first quarter of fiscal 20152015.

(9)        Warranty Obligations

The Company records a provision in cost of sales for estimated warranty obligations at the date products are sold. Adjustments are made as new information becomes available. The following provides a reconciliation of changes in the Company’s warranty reserve. The Company provides no other guarantees.

(10)     Fair Value

Fair ValuePursuant to the accounting guidance for fair value measurement and its subsequent updates, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., the “exit price”) in an orderly transaction between market participants at the measurement date. The accounting guidance establishes a hierarchy for inputs used in measuring fair value that minimizes the use of unobservable inputs by requiring the use of observable market data when available. Observable inputs are inputs that market participants would use in pricing the asset or liability based on active market data. Unobservable inputs are inputs that reflect the assumptions market participants would use in pricing the asset or liability based on the best information available in the circumstances.  

The fair value hierarchy is broken down into the three input levels summarized below:

The carrying amounts of the Company’s cash and cash-equivalents and line of credit approximate their fair values at each balance sheet date due to the short-term maturity of these financial instruments. The fair values of term debt are based on the present value of expected future cash flows and assumptions about current interest rates and the creditworthiness of the Company (Level 3). At SeptemberDecember 26, 2015 and March 28, 2015, the carrying amounts of the Company’s term debt totaled $730,000$575,000 and $1.1 million respectively and the estimated fair value totaled $725,000$590,000 and $1.2 million respectively. The fair value was calculated using a discounted cash flow model and utilized ana 20% and 18% discount rate which isrespectively. The rates are commensurate with market rates given the remaining term, principal repayment schedule, the Company’s creditworthiness and outstanding loan balance.

The Company’s derivative warrant liability is measured at fair value on a recurring basis and is categorized as Level 3 in the fair value hierarchy. The derivative warrant liability is valued using the Monte Carlo simulation model, using the following assumptions as of SeptemberDecember 26, 2015: (i) the remaining expected life of 3.53.3 years, (ii) the Company’s historical volatility rate of 105.7%116.1%, (iii) risk-free interest rate of 1.18%1.38%, and (iv) a discount rate of eighteentwenty percent.

The Company’s assets and liabilities that are recognized and measured at fair value on a recurring basis are as follows:

(1(11)1)   Accounts Receivable Line of Credit

On June 1, 2015 the Company entered into a $2.5 million Revolving Accounts Receivable Line of Credit agreement with Bridge Bank. The credit facility agreement replaced the line of credit with SVB which expired April 15, 2015. The agreement provides for a maximum borrowing capacity of $2.5 million of which $2.0 million is subject to a borrowing base calculation and $500,000 is non-formula based.

The loan is secured by all assets of the Company including intellectual property and general intangibles and provides for a borrowing capacity equal to 80% of eligible accounts receivable. The loan matures on May 6, 2017 and bears an interest rate, equal to 1.5% over the bank’s prime rate of interest (which was 3.25% at the date of closing resulting in an interest rate of 4.75%). Interest is payable monthly with principal due upon maturity. The Company paid a commitment fee of $12,500, and an additional $12,500 is due on the first anniversary of the loan closing. The loan agreement contains financial and non-financial covenants that are customary for this type of lending and includes a covenant to maintain an asset coverage ratio of at least 135% (defined as unrestricted cash and cash equivalents maintained with Bridge Bank, plus eligible accounts receivable aged less than 90 days from the invoice date, divided by the total amount of outstanding principal of all obligations under the loan agreement). As of SeptemberDecember 26, 2015, the Company was in compliance with all the financial covenants under the agreement. The line of credit requires a lockbox arrangement, which provides for receipts to be swept daily to reduce borrowings outstanding at the discretion of Bridge Bank. This arrangement, combined with the existence of the subjective acceleration clause in the line of credit agreement, necessitates the line of credit be classified as a current liability on the balance sheet. The acceleration clause allows for amounts due under the facility to become immediately due in the event of a material adverse change in the Company’s business condition (financial or otherwise), operations, properties or prospects, or ability to repay the credit based on the lender's judgment. As of SeptemberDecember 26, 2015, the Company’s total outstanding borrowings and remaining borrowing capacity under the Bridge Bank line of credit were $950,000$1.2 million and $1.0 million,$895,000, respectively.

(12)     Term Loan, Revolving Line of Credit and Warrants

On March 13, 2014 the Company entered into a three year, $2.0 million term loan agreement with PFG under which the Company received $1.0 million on March 14, 2014. Pursuant to the agreement, the Company had the ability to borrow an additional $1.0 million following the Company’s achievement of certain performance milestones which included achieving $7.5 million in net sales during the first half of fiscal 2015 and two consecutive quarters of net income greater than zero during fiscal 2015.

On June 16, 2014, the Company amended its loan agreement with PFG (the “Amendment”). Under the terms of the Amendment, PFG made a revolving credit line available to Giga-tronics in the amount of $500,000, and the Company borrowed the entire amount on June 17, 2014. The revolving line had a 33 month term. The Amendment also reduced the Company’s potential future borrowing availability under the PFG Loan agreement from $1.0 million to $500,000.The interest on the PFG revolving credit line was fixed, calculated on a daily basis at a rate of 12.50% per annum. The Company was allowed to prepay the loan at any time prior to its March 13, 2017 maturity date without a penalty. Beginning in October 2014, PFG had the right to convert the $500,000 revolving loan into a term loan and require principal payments to be amortized over the remaining loan term. On April 25, 2015, PFG exercised this right, and fully amortizing principal and interest payments began in May 2015.

On June 3, 2015, and following the Company’s new line of credit agreement with Bridge Bank (see Note 11, Accounts Receivable Line of Credit), the Company’s loan agreement with PFG was further amended (the “Second Amendment”). The Second Amendment cancelled the Company’s $500,000 of borrowing availability under the June 2014 Amendment and required the Company to pay PFG $150,000 towards its existing $500,000 outstanding balance under the revolving line of credit, in which the Company paid in July 2015. The Company also agreed to pay PFG an additional $10,000 per month towards its remaining credit line balance until repaid, followed by like payments towards its term loan balance until repaid. The Company expects to pay off the credit line by April 1, 2016. As of December 26, 2015, the Company’s total outstanding principal balance under the revolving credit line loan was $120,000.

Interest on the initial $1.0 million term loan is fixed at 9.75% and required monthly interest only payments during the first sixnine months of the agreement followed by monthly principal and interest payments over the remaining 30 months. The Company may prepay the loan at any time prior to maturity by paying all future scheduled principal and interest payments. As of SeptemberDecember 26, 2015, the Company’s total outstanding principal balance under the PFG term loan was $600,000.

As of September 26, 2015, the Company’s total outstanding principal balance under the revolving credit line loan was $208,000.$500,000.

The PFG loan is secured by all of the assets of the Company under a lien that is junior to the Bridge Bank debt agreement described in Note 11, and limits borrowing under the Bridge Bank credit line to $2.5 million. The Company paid a loan fee of $30,000 upon the initial draw (“First Draw”), $15,000 for the June 2014 Amendment and $5,000 for the Second Amendment. The loan fees paid are recorded as prepaid expenses and amortized to interest expense over the remaining term of the PFG amended loan agreement.  

The PFG loan agreement contains financial covenants associated with the Company achieving minimum quarterly net sales and maintaining a minimum monthly shareholders’ equity. In the event of default by the Company, all or any part of the Company’s obligations to PFG could become immediately due. As of the quarter ended SeptemberDecember 26, 2015, the Company was not in compliance with the revenue financial covenant under the agreement. As a result, the Company notified PFG of the non-compliance and PFG provided the Company a waiver on October 8, 2015 related to the non-compliance which required a $10,000 cash payment by the Company. The Company paid this amount on October 13, 2015.

The loan agreement also provided for the issuance of warrants convertible into 300,000 shares of the Company’s common stock, of which 180,000 were exercisable upon receipt of the initial $1.0 million from the First Draw, and 80,000 became exercisable with the Amendment. The Second Amendment terminated the additional 40,000 warrants that would have become exercisable as part of cancelling the remaining $500,000 that was available under the Amendment. Each warrant issued under the loan agreement has a term of five years from the First Draw and an exercise price of $1.42 which was equal to the average NASDAQ closing price of the Company’s common stock for the ten trading days prior to the First Draw.

If the warrants are not exercised before expiration on March 13, 2019, the Company would be required to pay PFG $150,000 and $67,000 as settlement for warrants associated with the First Draw and the Amendment, respectively. The warrants could be settled for cash at an earlier date in the event of any acquisition or other change in control of the Company, future public issuance of Company securities or liquidation (or substantially similar event) of the Company. The Company currently has no plans for any of the aforementioned events, and as a result, the cash payment date is estimated to be the expiration date unless warrants are exercised before then. The warrants have the characteristics of both debt and equity and are accounted for as a derivative liability measured at fair value each reporting period with the change in fair value recorded in earnings. The initial fair value of the warrants associated with the First Draw and Amendment were $128,000 and $123,000, respectively.

As of SeptemberDecember 26, 2015, the estimated fair values of the derivative liabilities associated with the warrants issued in connection with the First Draw and Amendment were $176,000$235,000 and $118,000,$157,000, respectively, for a combined value of $294,000.$392,000. The change in the fair value of the warrant liability totaled $110,000$98,000 for the three month period ended SeptemberDecember 26, 2015 and is reported in the accompanying statement of operations as a gainloss on adjustment of derivative liability to fair value.

The initial $1.0 million in proceeds under the term loan agreement were allocated between the PFG Loan and the warrants based on their relative fair values on the date of issuance which resulted in initial carrying values of $822,000 and $178,000, respectively. The resulting discount of $178,000 on the PFG Loan is being accreted to interest expense under the effective interest method over the three-year term of the PFG Loan.

The proceeds from the $500,000 credit line issued in connection with the Amendment were allocated between the PFG Loan and the warrants based on their relative fair values on the date of issuance which resulted in initial carrying values of $365,000 and $135,000, respectively. The resulting discounts of $135,000 on the PFG Loan is being accreted to interest expense under the effective interest method over the remaining term of the PFG Loan.

For the three month periods ended SeptemberDecember 26, 2015 and SeptemberDecember 27, 2014, the Company recorded accretion of discount expense associated with the PFG Loan of $63,000$34,000 and $45,000 respectively. For the sixnine month period ended SeptemberDecember 26, 2015 and SeptemberDecember 27, 2014, the Company recorded accretion of discount expense associated with the PFG Loan of $105,000$140,000 and $69,000$115,000 respectively. 

(13)      Series B, C, D Convertible Voting Perpetual Preferred Stock and Warrants

On November 10, 2011, the Company received $2,199,000 in cash proceeds from Alara Capital AVI II, LLC, a Delaware limited liability company (the “Investor”), an investment vehicle sponsored by Active Value Investors, LLC, under a Securities Purchase Agreement entered into on October 31, 2011. Under the terms of the Securities Purchase Agreement, the Company issued 9,997 shares of its Series B Convertible Voting Perpetual Preferred Stock (“Series B Preferred Stock”) to the Investor at a price of $220 per share. The Company has recorded $2.0 million as Series B Preferred Stock on the consolidated balance sheet which is net of stock offering costs of approximately $202,000 and represents the value attributable to both the convertible preferred stock and warrants issued to the Investor. After considering the value of the warrants, the effective conversion price of the preferred stock was greater than the common stock price on date of issue and therefore no beneficial conversion feature was present. 

On February 19, 2013, the Company entered into a Securities Purchase Agreement pursuant to which it agreed to sell 3,424.65 shares of its Series C Convertible Voting Perpetual Preferred Stock (“Series C Preferred Stock”) to the Investor, for aggregate consideration of $500,000, which is approximately $146.00 per share. The Company has recorded $457,000 as Series C Preferred Stock on the consolidated balance sheet, which is net of stock offering costs of approximately $43,000.After considering the reduction in the value of the warrant, the effective conversion price of the preferred stock was greater than the common stock price on the date of issue and therefore no beneficial conversion feature was present.

On July 8, 2013 the Company received $817,000 in net cash proceeds from the Investor under a Securities Purchase Agreement. The Company sold to the Investor 5,111.86 shares of its Series D Convertible Voting Perpetual Preferred Stock (Series D Preferred Stock) and a warrant to purchase up to 511,186 additional shares of common stock at the price of $1.43 per share. The allocation of the $858,000 in gross proceeds from issuance of Series D Preferred Stock based on the relative fair values resulted in an allocation of $498,000 (which was recorded net of $41,000 of issuance costs) to Series D Preferred Stock and $360,000 to Common Stock. In addition, because the effective conversion rate based on the $498,000 allocated to Series D Preferred Stock was $0.97 per common share which was less than the Company’s stock price on the date of issuance, a beneficial conversion feature was present at the issuance date. The beneficial conversion feature totaled$238,000 and was recorded as an increase of common stock and an increase to accumulated deficit.

Each share of Series B, Series C and Series D Preferred Stock is convertible into one hundred shares of the Company’s common stock. The investor also held warrants to purchase 1,017,405 shares at an exercise price of $1.43 per share which were exercised in February and May 2015 as discussed in Note 14, Exercise of Series C and Series D Warrants.

The table below presents information as of SeptemberDecember 26, 2015 and March 28, 2015.

(14)(14) Exercise of Series C and Series D Warrants

On February 16, 2015, the Company entered into a Securities Purchase Agreement and Warrant Agreement with Alara Capital AVI II, LLC in which the Company received total gross cash proceeds of approximately $1.5 million. Funds were received from Alara in separate closings dated February 16, 2015 and February 23, 2015 in which Alara exercised a total of 1,002,818 of its existing Series C and Series D warrants to purchase common shares, all of which had an exercise price of $1.43 per share for total cash proceeds of $1,434,000, which was recorded net of $42,000 of stock issuance costs. As part of the consideration for this exercise, the Company sold to Alara two new warrants (“new Warrants”) to purchase an additional 898,634 and 194,437 common shares at an exercise price of $1.78 and $1.76 per share, respectively, for a total purchase price of $137,000 or $0.125 per share,share.
