PART I

Item 1. Business.

The Company was incorporated in the State of New York on July 22, 1955 and is engaged in the design, development, manufacture and marketing of shock absorption, rate control, and energy storage devices for use in various types of machinery, equipment and structures. In addition to manufacturing and selling existing product lines, the Company continues to develop new and advanced technology products.

Principal Products

The Company manufactures and sells a single group of very similar products that have many different applications for customers. These similar products are included in one of six categories; namely, Seismic Dampers, Fluidicshoks®, Crane and Industrial Buffers, Self-Adjusting Shock Absorbers, Liquid Die Springs, and Vibration Dampers. Management does not track or otherwise account for sales broken down by these categories. The following is a summary of the capabilities and applications for these products.

Seismic Dampers are designed to ameliorate the effects of earthquake tremors on structures, and represent a substantial part of the business of the Company. Fluidicshoks® are small, extremely compact shock absorbers with up to 19,200 inch-pound capacities, produced in 15 standard sizes for primary use in the defense, aerospace and commercial industry. Crane and industrial buffers are larger versions of the Fluidicshoks® with up to 60,000,000 inch-pound capacities, produced in more than 60 standard sizes for industrial application on cranes, ships, container ships, railroad cars, truck docks, ladle and ingot cars, ore trolleys and car stops. Self-adjusting shock absorbers, which include versions of Fluidicshoks® and crane and industrial buffers, automatically adjust to different impact conditions, and are designed for high cycle application primarily in heavy industry. Liquid die springs are used as component parts of machinery and equipment used in the manufacture of tools and dies. Vibration dampers are used primarily by the aerospace and defense industries to control the response of electronics and optical systems subjected to air, ship, or spacecraft vibration.

Distribution

The Company uses the services of more than 50 sales representatives and distributors in the United States and Canada. Specialized technical sales in aerospace and custom marketing activities are serviced by three sales agents, under the direction and with the assistance of Douglas P. Taylor, the Company's President. Sales representatives typically have non-exclusive, yearly agreements with the Company, which, in most instances, provide for payment of commissions on sales at 10% of the product's net aggregate selling price. Distributors also have non-exclusive, yearly agreements with the Company to purchase the Company's products for resale purposes.

Competition

The Company faces competition on mature aerospace and defense programs which may use more conventional products manufactured under less stringent government specifications. Two foreign companies are the Company's competitors in the production of crane buffers.

The Company's principal competitor for the manufacture of products in the aerospace and commercial aerospace industries field is UTC Aerospace Systems Division of United Technologies in Ft. Worth, Texas. While the Company is competitive with this company in the areas of pricing, warranty and product performance, due to limited financing and manufacturing facilities, the Company cannot compete in the area of volume production.

The Company competes directly against two other firms supplying seismic damping devices, as well as numerous other firms which supply alternative seismic protection technologies.

Raw Materials and Supplies

The principal raw materials and supplies used by the Company in the manufacture of its products are provided by numerous U.S. and foreign suppliers. The loss of any one of these would not materially affect the Company's operations.

Dependence Upon Major Customers

Sales to one customer, Sinodynamics Enterprise Co., Ltd., approximated 29% of net sales for 2013. The loss of this customer, unless the business is replaced by the Company, could result in an adverse effect on the results for the Company.

Patents, Trademarks and Licenses

The Company holds approximately 13 patents expiring at different times until the year 2031.

Terms of Sale

The Company does not carry significant inventory for rapid delivery to customers, and goods are not normally sold with return rights such as are available for consignment sales. The Company has no inventory out on consignment and no consignment sales for the years ended May 31, 2013 and 2012. No extended payment terms are offered. During the year ended May 31, 2013, delivery time after receipt of orders averaged 8 to 10 weeks for the Company's standard products. Due to the volatility of construction and aerospace/defense programs, progress payments are usually required for larger projects using custom designed components of the Company.

Need for any Government Approval of Principal Products or Services

Contracts between the Company and the federal government or its independent contractors are subject to termination at the election of the federal government. Contracts are generally entered into on a fixed price basis. If the federal government should limit defense spending, these contracts could be reduced or terminated, which management believes would have a materially adverse effect on the Company.

Research and Development

The Company does not generally engage in major product research and development activities in connection with the design of its products, except when funded by aerospace customers or the federal government. The Company, however, engages in research testing of its products. For the fiscal years ended May 31, 2013 and 2012, the Company expended $300,000 and $422,000, respectively, on manufacturing research. For the years ended May 31, 2013 and 2012, defense sponsored research and development totaled $163,000 and $119,000, respectively.

Government Regulation

Compliance with federal, state and local laws and regulations which have been enacted or adopted regulating the discharge of materials into the environment has had no material effect on the Company, and the Company believes that it is in substantial compliance with such provisions.

The Company is subject to the Occupational Safety and Health Act ("OSHA") and the rules and regulations promulgated thereunder, which establish strict standards for the protection of employees, and impose fines for violations of such standards. The Company believes that it is in substantial compliance with OSHA provisions and does not anticipate any material corrective expenditures in the near future. The Company is currently incurring only moderate costs with respect to disposal of hazardous waste and compliance with OSHA regulations.

The Company is also subject to regulations relating to production of products for the federal government. These regulations allow for frequent governmental audits of the Company's operations and fairly extensive testing of Company products. The Company believes that it is in substantial compliance with these regulations and does not anticipate corrective expenditures in the future.

Employees

Exclusive of Company sales representatives and distributors, as of May 31, 2013, the Company had 102 employees, including three executive officers, and four part time employees. The Company has good relations with its employees.

Item 1A. Risk Factors.

Smaller reporting companies are not required to provide the information required by this item.

Item 1B. Unresolved Staff Comments.

Not applicable.

Item 2. Properties

The Company's production facilities occupy approximately six acres on Tonawanda Island in North Tonawanda, New York and are comprised of four interconnected buildings and two adjacent buildings. The production facilities consist of a small parts plant (approximately 4,400 square feet), a large parts plant (approximately 13,500 square feet), and include a facility of approximately 7,000 square feet comprised of a test facility, storage area, pump area and the Company's general offices. One adjacent building is a 17,000 square foot seismic assembly test facility. Another adjacent building (approximately 2,000 square feet) is used as a training facility. These facilities total more than 45,000 square feet. Adjacent to these facilities, the Company has a remote test facility used for shock testing. This state-of-the-art test facility is 1,200 square feet. The small parts plant consists of a complete small machine shop and tool room that produces all of the Company's product items which are less than two inches in diameter. The large parts plant consists of a complete large machine shop and tool room. Both plants contain custom-built machinery for boring, deep-hole drilling and turning of parts.

The Company's real properties are subject to a negative pledge agreement with its lender, First Niagara Bank. The Company has agreed with the lender that, for so long as the credit facilities with the lender are outstanding, the Company will not sell, lease or mortgage any of its real properties. Additional information regarding the Company's agreement with First Niagara Bank is contained in Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations, at "Capital Resources, Line of Credit and Long-Term Debt."

The Company leases a separate warehouse for storage from an unrelated third party, consisting of approximately 3,600 square feet at $975 per month. The warehouse is located approximately one-quarter mile from the above-referenced production facilities and office space. The total rental expense incurred by the Company for this facility in fiscal 2013 was $11,700. The Company also leases a separate facility for painting, packaging and shipping from an unrelated third party, consisting of approximately 12,600 square feet at $5,292 per month. The facility is located in the Town of Tonawanda, New York, approximately four miles from the above-referenced production facilities and office space. The total rental expense incurred by the Company for this facility in fiscal 2013 was $63,504. The Company terminated the lease on this facility in June 2013 as all operations which were performed at this leased facility were moved to the recently renovated facilities, noted below.

The Company owns three additional industrial buildings on nine acres of land in the City of North Tonawanda located 1.4 miles from the Company’s headquarters on Tonawanda Island. Total area of the three buildings is 46,000 square feet. Two of the three buildings are now occupied and the Company’s painting operations have been relocated to the facility. Work continues on the third building, which is expected to be completed in the summer of 2013. When the remaining building is fully renovated, the Company’s production machinery will be relocated from the Company’s Tonawanda Island site, and large overhead cranes will be installed to move large parts from machine to machine. The Company plans to move all machining and metalworking operations to the new site in the autumn of 2013. This will allow the former machining areas at the existing Tonawanda Island site to house greatly expanded assembly and product testing areas. All corporate and engineering offices will be unaffected by the change and will remain on Tonawanda Island.

The renovations and modifications to the buildings are extensive, with a total construction cost of $2.9 million. The Company anticipates that its current cash and bank line of credit resources will be sufficient for that purpose.

The Company believes it is carrying adequate insurance coverage on its facilities and their contents.

Item 3. Legal Proceedings.

There are no legal proceedings except for routine litigation incidental to the business.

Item 4. Mine Safety Disclosures.

Not applicable.

PART II

Item 5. Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases Of Equity Securities.

Market Information

The Company's Common Stock trades on the NASDAQ Capital Market of the National Association of Securities Dealers Automated Quotation ("NASDAQ") stock market under the symbol TAYD. The high and low sales information noted below for the quarters of fiscal year 2013 and fiscal year 2012 were obtained from NASDAQ.

	Fiscal 2013		Fiscal 2012
	High	Low	High	Low
First Quarter	9.58	7.81	6.75	5.00
Second Quarter	9.10	7.24	9.00	6.17
Third Quarter	9.73	7.69	11.50	6.53
Fourth Quarter	9.00	7.58	12.18	8.51

Holders

As of August 13, 2013, the number of issued and outstanding shares of Common Stock was 3,341,385 and the approximate number of record holders of the Company's Common Stock was 732. Due to a substantial number of shares of the Company's Common Stock held in street name, the Company believes that the total number of beneficial owners of its Common Stock exceeds 2,000.

Dividends

No cash or stock dividends have been declared during the last two fiscal years. The Company plans to retain cash in the foreseeable future to fund working capital needs.

As of September 15, 2008, the Company's Board of Directors adopted a shareholder rights plan designed to deter coercive or unfair takeover tactics and prevent an acquirer from gaining control of the Company without offering a fair price to shareholders. Under the plan, certain rights ("Rights") were distributed as a dividend on each share of Common Stock (one Right for each share of Common Stock) held as of the close of business on October 3, 2008. Each whole Right entitles the holder, under certain defined conditions, to buy one two-thousandths (1/2000) of a newly issued share of the Company's Series 2008 Junior Participating Preferred Stock ("Series 2008 Preferred Stock") at a purchase price of $5.00 per unit of one two-thousandths of a share. Rights attach to and trade with the shares of Common Stock, without being evidenced by a separate certificate. No separate Rights certificates will be issued unless and until the Rights detach from Common Stock and become exercisable for shares of the Series 2008 Preferred Stock.

The Rights become exercisable to purchase shares of Preferred Stock (or, in certain circumstances, Common Stock) only if (i) a person acquired 15% or more of the Company's Common Stock, or (ii) a person commenced a tender or exchange offer for 10% or more of the Company's Common Stock, or (iii) the Board of Directors determined that the beneficial owner of at least 10% of the Company's Common Stock intended to cause the Company to take certain actions adverse to it and its shareholders or that such ownership would have a material adverse effect on the Company. The Rights Plan will expire on October 5, 2018.

Issuer Purchases of Equity Securities

The Company did not repurchase any shares of its common stock during the year ended May 31, 2013. On November 2, 2012, the Board of Directors of the Registrant voted unanimously to continue the share repurchase agreement, authorized by the Board in 2010, with Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S") under which the Company repurchases shares of its common stock. The Company has designated $419,815 of cash on hand as available for open-market purchases. Since Board authorization in 2010, a total of 15,600 shares have been purchased at an average price per share of $5.14. Repurchases are made by MLPF&S for the benefit of the Registrant.

Item 6. Selected Financial Data

The Company qualifies as a smaller reporting company, as defined by 17 CFR §229.10(f)(1), and is not required to provide the information required by this Item.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations.

Cautionary Statement

The Private Securities Litigation Reform Act of 1995 provides a "safe harbor" for forward-looking statements. Information in this Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations" and elsewhere in this 10-K that does not consist of historical facts are "forward-looking statements." Statements accompanied or qualified by, or containing, words such as "may," "will," "should," "believes," "expects," "intends," "plans," "projects," "estimates," "predicts," "potential," "outlook," "forecast," "anticipates," "presume," "assume" and "optimistic" constitute forward-looking statements and, as such, are not a guarantee of future performance. The statements involve factors, risks and uncertainties, the impact or occurrence of which can cause actual results to differ materially from the expected results described in such statements. Risks and uncertainties can include, among others, fluctuations in general business cycles and changing economic conditions; changing product demand and industry capacity; increased competition and pricing pressures; advances in technology that can reduce the demand for the Company's products, as well as other factors, many or all of which may be beyond the Company's control. Consequently, investors should not place undue reliance on forward-looking statements as predictive of future results. The Company disclaims any obligation to release publicly any updates or revisions to the forward-looking statements herein to reflect any change in the Company's expectations with regard thereto, or any changes in events, conditions or circumstances on which any such statement is based.

Application of Critical Accounting Policies and Estimates

The Company's consolidated financial statements and accompanying notes are prepared in accordance with U.S. generally accepted accounting principles. The preparation of the Company's financial statements requires management to make estimates, assumptions and judgments that affect the amounts reported. These estimates, assumptions and judgments are affected by management's application of accounting policies, which are discussed in Note 1. "Summary of Significant Accounting Policies" and elsewhere in the accompanying consolidated financial statements. As discussed below, our financial position or results of operations may be materially affected when reported under different conditions or when using different assumptions in the application of such policies. In the event estimates or assumptions prove to be different from actual amounts, adjustments are made in subsequent periods to reflect more current information. Management believes the following critical accounting policies affect the more significant judgments and estimates used in the preparation of the Company's financial statements.

Accounts Receivable

Our ability to collect outstanding receivables from our customers is critical to our operating performance and cash flows. Accounts receivable are stated at an amount management expects to collect from outstanding balances. Management provides for probable uncollectible accounts through a charge to earnings and a credit to a valuation allowance based on its assessment of the current status of individual accounts after considering the age of each receivable and communications with the customers involved. Balances that are collected, for which a credit to a valuation allowance had previously been recorded, result in a current-period reversal of the earlier transaction charging earnings and crediting a valuation allowance. Balances that are still outstanding after management has used reasonable collection efforts are written off through a charge to the valuation allowance and a credit to accounts receivable in the current period. The actual amount of accounts written off over the five year period ended May 31, 2013 equaled less than 0.1% of sales for that period. The balance of the valuation allowance remained constant since May 31, 2009 at the current level of $42,000. Management does not expect the valuation allowance to materially change in the next twelve months for the current accounts receivable balance.

Inventory

Inventory is stated at the lower of average cost or market. Average cost approximates first-in, first-out cost.

Maintenance and other inventory represent stock that is estimated to have a product life-cycle in excess of twelve-months. This stock represents certain items the Company is required to maintain for service of products sold, and items that are generally subject to spontaneous ordering.

This inventory is particularly sensitive to technical obsolescence in the near term due to its use in industries characterized by the continuous introduction of new product lines, rapid technological advances and product obsolescence. Therefore, management of the Company has recorded an allowance for potential inventory obsolescence. Based on certain assumptions and judgments made from the information available at that time, we determine the amount in the inventory allowance. If these estimates and related assumptions or the market changes, we may be required to record additional reserves. Historically, actual results have not varied materially from the Company's estimates.

The provision for potential inventory obsolescence was $180,000 for each of the years ended May 31, 2013 and 2012.

Revenue Recognition

Sales are recognized when units are delivered or services are performed. Sales under fixed-price contracts are recorded as deliveries are made at the contract sales price of the units delivered. Sales under certain fixed-price contracts requiring substantial performance over several periods prior to commencement of deliveries, are accounted for under the percentage-of-completion method of accounting whereby revenues are recognized based on estimates of completion prepared on a ratio of cost to total estimated cost basis. Costs include all material and direct and indirect charges related to specific contracts. Other expenses are charged to operations, as incurred. Total estimated costs for each of the contracts are estimated based on a combination of historical costs of manufacturing similar products and estimates or quotes from vendors for supplying parts or services towards the completion of the manufacturing process. Adjustments to cost and profit estimates are made periodically due to changes in job performance, job conditions and estimated profitability, including those arising from final contract settlements. These changes may result in revisions to costs and income and are recognized in the period in which the revisions are determined. Any losses expected to be incurred on contracts in progress are charged to operations in the period such losses are determined. If total costs calculated upon completion of the manufacturing process in the current period for a contract are more than the estimated total costs at completion used to calculate revenue in a prior period, then the revenue and profits in the current period will be lower than if the estimated costs used in the prior period calculation were equal to the actual total costs upon completion. Historically, actual results have not varied materially from the Company's estimates. In the fiscal year ended May 31, 2013, 58% of total revenue recognized was accounted for using the percentage-of-completion method of accounting while the remaining 42% of revenue was recorded as deliveries were made to our customers. In the fiscal year ended May 31, 2012, 77% of total revenue recognized was accounted for using the percentage-of-completion method of accounting while the remaining 23% of revenue was recorded as deliveries were made to our customers.

For financial statement presentation purposes, the Company nets progress billings against the total costs incurred on uncompleted contracts. The asset, "costs and estimated earnings in excess of billings," represents revenues recognized in excess of amounts billed. The liability, "billings in excess of costs and estimated earnings," represents billings in excess of revenues recognized.

Income Taxes

The provision for income taxes provides for the tax effects of transactions reported in the financial statements regardless of when such taxes are payable. Deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the tax and financial statement basis of assets and liabilities. The deferred tax assets relate principally to asset valuation allowances such as inventory obsolescence reserves and bad debt reserves and also to liabilities including warranty reserves, accrued vacation, accrued commissions and others. The deferred tax liabilities relate primarily to differences between financial statement and tax depreciation. Deferred taxes are based on tax laws currently enacted with tax rates expected to be in effect when the taxes are actually paid or recovered.

Realization of the deferred tax assets is dependent on generating sufficient taxable income at the time temporary differences become deductible. The Company provides a valuation allowance to the extent that deferred tax assets may not be realized. A valuation allowance has not been recorded against the deferred tax assets since management believes it is more likely than not that the deferred tax assets are recoverable. The Company considers future taxable income and potential tax planning strategies in assessing the need for a potential valuation allowance. In future years the Company will need to generate approximately $3.1 million of taxable income in order to realize our deferred tax assets recorded as of May 31, 2013 of $1,063,000. This deferred tax asset balance is 12% ($112,000) higher than at the end of the prior year. The amount of the deferred tax assets considered realizable however, could be reduced in the near term if estimates of future taxable income are reduced. If actual results differ from estimated results or if the Company adjusts these assumptions, the Company may need to adjust its deferred tax assets or liabilities, which could impact its effective tax rate. Historically, actual results have not varied materially from the Company's estimates.

The Company's practice is to recognize interest related to income tax matters in interest income / expense and to recognize penalties in selling, general and administrative expenses.

The Company and its subsidiary file consolidated Federal and State income tax returns. As of May 31, 2013, the Company had State investment tax credit carryforwards of approximately $142,000 expiring through May 2019.

Results of Operations

A summary of the period to period changes in the principal items included in the consolidated statements of income is shown below:

Summary comparison of the years ended May 31, 2013 and 2012
	Increase /
	(Decrease)
Sales, net	$  (4,277,000)
Cost of goods sold	$  (4,175,000)
Selling, general and administrative expenses	$     (682,000)
Income before provision for income taxes	$      511,000
Provision for income taxes	$      162,000
Net income	$      349,000

For the year ended May 31, 2013 (All figures being discussed are for the year ended May 31, 2013 as compared to the year ended May 31, 2012.)

	Year ended May 31		Change
	2013	2012	Amount		Percent
Net Revenue	$24,730,000	$29,007,000	$(4,277,000	)	-15%
Cost of sales	15,966,000	20,141,000	(4,175,000	)	-21%
Gross profit	$  8,764,000	$  8,866,000	$   (102,000	)	-1%
… as a percentage of net revenues	35%	31%

The Company's consolidated results of operations showed a 15% decrease in net revenues and an increase in net income of 16%. Gross profit decreased by 1%. Revenue in the prior year was bolstered by record high shipments of Taylor Devices’ Seismic Dampers, largely to Asia. Last year’s increase in demand for these products had been influenced by major earthquakes in Asia over the past several years. In the current period, revenues accounted for under the percentage-of-completion method of accounting decreased by 35% from the level recorded in the prior year. This decrease is primarily due to less projects in process in the current year (59 in fiscal 2013; 75 in fiscal 2012). Of the 59 projects in process during this year, 16 were still in process at 5/31/13 compared with the prior year when 28 of the 75 projects worked on were still in process at 5/31/12. The average value of these projects in-process at the end of the current fiscal year ($415,000) decreased by 42% from the projects in-process at the end of the prior fiscal year ($715,000). The projects in the current year are 52% complete in the aggregate as compared with 61% for those in process at 5/31/12. Revenues recorded for all other product sales increased by 55% from last year. This fluctuation is attributable primarily to an increase in sales to customers in aerospace and defense from the prior year. The gross profit as a percentage of net revenues for the current and prior year periods was 35% and 31%, respectively.

The mix of customers buying our products changed from last year. Sales of the Company's products are made to three general groups of customers: industrial, construction and aerospace / defense. A 32% decrease in sales to construction customers who were seeking seismic / wind protection for either building new buildings and bridges or retrofitting existing buildings and bridges from last year’s level was offset, somewhat, by a 24% increase in sales to aerospace / defense customers and a 33% increase in sales to customers using our products in industrial applications. A breakdown of sales to these three general groups of customers is as follows:

	Year ended May 31
	2013	2012
Industrial	10%	6%
Construction	57%	71%
Aerospace / Defense	33%	23%

At May 31, 2012, we had 151 open sales orders in our backlog with a total sales value of $17.5 million. At May 31, 2013, we had 108 open sales orders in our backlog and the total sales value is $13.1 million. $3.2 million of the current backlog is on projects already in progress. $8.0 million of the $17.5 million sales order backlog at May 31, 2012 was in progress at that date. 59% of the sales value in the backlog is for aerospace / defense customers compared to 38% at the end of fiscal 2012. As a percentage of the total sales order backlog, orders from customers in construction accounted for 38% at May 31, 2013 and 67% at May 31, 2012.

The Company's backlog, revenues, commission expense, gross margins, gross profits, and net income fluctuate from period to period. The changes in the current period, compared to the prior period, are not necessarily representative of future results.

Net revenue by geographic region, as a percentage of total net revenue for fiscal years ended May 31, 2013 and 2012 is as follows:

	Year ended May 31
	2013	2012
North America	55%	40%
Asia	41%	54%
Other	4%	6%

Selling, General and Administrative Expenses

	Year ended May 31		Change
	2013	2012	Amount		Percent
Outside Commissions	$   858,000	$1,228,000	$   (370,000	)	-30%
Other SG&A	4,439,000	4,751,000	(312,000	)	-7%
Total SG&A	$5,297,000	$5,979,000	$  (682,000	)	-11%
… as a percentage of net revenues	21%	21%

Selling, general and administrative expenses decreased by 11% from the prior year. Outside commission expense decreased 30% from last year's level. This fluctuation was primarily due to the decrease in the level of sales from last year to this. Other selling, general and administrative expenses decreased by 7% from last year. This decrease is primarily attributable to a decrease in estimated employee incentive compensation expense in the current period related to the lower level of sales.

The above factors resulted in operating income of $3,467,000 for the year ended May 31, 2013, up 20% from the $2,887,000 in the prior year.

The Company's effective tax rate (ETR) is calculated based upon current assumptions relating to the year's operating results and various tax related items. The ETR for the fiscal year ended May 31, 2013 is 26.4%, slightly more than the ETR for the prior year of 25.4%. A reconciliation of provision for income taxes at the statutory rate to income tax provision at the Company's effective rate is as follows:

	2013		2012
Computed tax provision at the expected statutory rate	$1,176,000			$1,003,000
State income tax - net of Federal tax benefit	(3,000	)		2,000
Tax effect of permanent differences:
Research tax credits	(213,000	)		(207,000	)
Other permanent differences	(30,000	)		(27,000	)
Other	(18,000	)		(21,000	)
	$   912,000			$   750,000

Stock Options

The Company has stock option plans which provides for the granting of nonqualified or incentive stock options to officers, key employees and non-employee directors. Options granted under the plans are exercisable over a ten year term. Options not exercised by the end of the term expire.

The Company measures compensation cost arising from the grant of share-based payments to employees at fair value and recognizes such cost in income over the period during which the employee is required to provide service in exchange for the award. The Company recognized $110,000 and $117,000 of compensation cost for the years ended May 31, 2013 and 2012.

The fair value of each stock option grant has been determined using the Black-Scholes model. The model considers assumptions related to exercise price, expected volatility, risk-free interest rate, and the weighted average expected term of the stock option grants. The Company used a weighted average expected term. Expected volatility assumptions utilized in the model were based on volatility of the Company's stock price for the thirty month period immediately preceding the granting of the options. The Company issued stock options in August 2012 and April 2013. The risk-free interest rate is derived from the U.S. treasury yield.

The following assumptions were used in the Black-Scholes model in estimating the fair market value of the Company's stock option grants:

	August 2012	April 2013
Risk-free interest rate:	1.875%	2.375%
Expected life of the options:	2.9 years	2.9 years
Expected share price volatility:	43%	44%
Expected dividends:	zero	zero
These assumptions resulted in estimated fair-market value per stock option:	$2.46	$2.47

The ultimate value of the options will depend on the future price of the Company's common stock, which cannot be forecast with reasonable accuracy. A summary of changes in the stock options outstanding during the year ended May 31, 2013 is presented below.

		Weighted-
	Number of	Average
	Options	Exercise Price
Options outstanding and exercisable at May 31, 2012:	163,750	$6.30
Options granted:	44,500	$7.84

Capital Resources, Line of Credit and Long-Term Debt

The Company's primary liquidity is dependent upon its working capital needs. These are primarily inventory, accounts receivable, costs and estimated earnings in excess of billings, accounts payable, accrued commissions, billings in excess of costs and estimated earnings, and debt service. The Company's primary sources of liquidity have been operations and bank financing.

Capital expenditures for the year ended May 31, 2013 were $3,293,000 compared to $1,550,000 in the prior year. The Company has commitments to make capital expenditures of $496,000 as of May 31, 2013. These purchases are related to the substantial renovation of the new buildings acquired in the fiscal year ended May 31, 2012, as discussed in item 2, above.

The Company has a $6,000,000 demand line of credit from a bank, with interest payable at the Company's option of 30, 60, 90 or 180 day LIBOR rate plus 2.5% or the bank's prime rate less .25%. There is no outstanding balance at May 31, 2013. There was a $258,000 principal balance outstanding as of May 31, 2012. The outstanding balance on the line of credit fluctuates as the Company's various long-term projects progress. The line is secured by accounts receivable, equipment, inventory, and general intangibles, and a negative pledge of the Company's real property. This line of credit is subject to the usual terms and conditions applied by the bank and is subject to renewal annually. In conjunction with this line of credit, the Company agreed to the following covenants:

Covenant	Minimum per Covenant	Current Actual	When Measured
Minimum level of working capital	$3 million	$13.8 million	Quarterly
Minimum debt service coverage ratio	1.5:1	64:1	Fiscal Year-end

The bank is not committed to make loans under this line of credit and no commitment fee is charged.

The level of cash and cash equivalents has increased significantly from May 31, 2012 ($74,000) to May 31, 2013 ($1,998,000). This increase was due to a record high net income along with the changes in the assets and liabilities as itemized in the consolidated statements of cash flow. The assets that decreased the most from last year to this were accounts receivable and costs and estimated earnings in excess of billings. These changes are discussed below. The Company believes that cash on hand combined with the line of credit should be sufficient to fund its expansion plans described in Item 2 of this Report.

Inventory and Maintenance Inventory

	May 31, 2013		May 31, 2012		Increase /(Decrease)
Raw materials	$   583,000		$   622,000		($     39,000	)	-6%
Work in process	7,876,000		7,112,000		764,000		11%
Finished goods	665,000		638,000		27,000		4%
Inventory	9,124,000	91%	8,372,000	91%	752,000		9%
Maintenance and other inventory	904,000	9%	845,000	9%	59,000		7%
Total	$10,028,000	100%	$9,217,000	100%	$   811,000		9%
Inventory turnover	1.7		2.7

Inventory, at $9,124,000 as of May 31, 2013, is 9% higher than the prior year-end. Of this, approximately 86% is work in process, 7% is finished goods, and 7% is raw materials. All of the current inventory is expected to be consumed or sold within twelve months. The level of inventory will fluctuate from time to time due to the stage of completion of the non-project sales orders in progress at the time.

The Company continues to rework slow-moving inventory, where applicable, to convert it to product to be used on customer orders. There was approximately $149,000 of slow-moving inventory used during the year ended May 31, 2013. The Company disposed of approximately $268,000 and $26,000 of obsolete inventory during the years ended May 31, 2013 and 2012, respectively.

Accounts Receivable, Costs and Estimated Earnings in Excess of Billings (“CIEB) and Billings in Excess of Costs and Estimated Earnings (BIEC”)

	May 31, 2013	May 31, 2012	Increase /(Decrease)
Accounts receivable	$ 2,245,000	$5,610,000	$(3,365,000	)	-60%
CIEB	2,458,000	5,492,000	(3,034,000	)	-55%
Less: BIEC	172,000	669,000	(497,000	)	-74%
Net	$ 4,531,000	$10,433,000	$(5,902,000	)	-57%
Number of an average day’s sales outstanding in accounts receivable (DSO)	39	52

The Company combines the totals of accounts receivable, the asset CIEB, and the liability BIEC, to determine how much cash the Company will eventually realize from revenue recorded to date. As the accounts receivable figure rises in relation to the other two figures, the Company can anticipate increased cash receipts within the ensuing 30-60 days.

Accounts receivable of $2,245,000 as of May 31, 2013 includes approximately $355,000 of amounts retained by customers on long-term construction projects. This retained amount is almost 25% of the amount retained as May 31, 2012. The decrease is simply due to contractual requirements of certain open projects at the year ends. The Company expects to collect all of these amounts, including the retained amounts, during the next twelve months. The number of an average day's sales outstanding in accounts receivable (DSO) decreased from 52 days at May 31, 2012 to 39 days at May 31, 2013. The DSO is a function of 1.) the level of sales for an average day (for example, total sales for the past three months divided by 90 days) and 2.) the level of accounts receivable at the balance sheet date. The level of sales for an average day in the fourth quarter of the current year is just over half of the level in the fourth quarter of the prior year. This is consistent with the overall decrease in revenue for the quarter from the historic high of $9,643,000 last year to $5,152,000 this year. The level of accounts receivable at the end of the current year is 60% less than at the end of the prior year. The combination of these two factors caused the DSO to decrease from last year end to this. The decrease in the level of accounts receivable was due to: a.) the decrease in retained amounts on projects, as discussed above and b.) a significant decrease (92%) in the amount of billings to customers on projects in May 2013 over May 2012.

The status of the projects in-progress at the end of the current and prior fiscal years have changed in the factors affecting the year-end balances in the asset CIEB, and the liability BIEC:

	2013	2012
Number of projects in progress at year-end	16	28
Aggregate percent complete at year-end	52%	61%
Average total value of projects in progress at year-end	$415,000	$715,000
Percentage of total value invoiced to customer	18%	36%

There are 43% fewer projects in-process at the end of the current fiscal year as compared with the prior year end and the average value of those projects has decreased by 42% between those two dates.

As noted above, CIEB represents revenues recognized in excess of amounts billed. Whenever possible, the Company negotiates a provision in sales contracts to allow the Company to bill, and collect from the customer, payments in advance of shipments. Unfortunately, provisions such as this are often not possible. The $2,458,000 balance in this account at May 31, 2013 is a 55% decrease from the prior year-end. Generally, if progress billings are permitted under the terms of a project sales agreement, then the more complete the project is, the more progress billings will be permitted. The Company expects to bill the entire amount during the next twelve months. 37% of the CIEB balance as of the end of the last fiscal quarter, February 28, 2013, was billed to those customers in the current fiscal quarter ended May 31, 2013. The remainder will be billed as the projects progress, in accordance with the terms specified in the various contracts.

As of May 31, 2013, there are sales orders for nine projects that are not yet in progress. These projects average $253,000 each in value upon completion. This compares to thirteen such projects as of the prior year end with an average value of $279,000.

The year-end balances in the CIEB account are comprised of the following components:

	May 31, 2013	May 31, 2012
Costs	$  2,752,000	$  9,342,000
Estimated earnings	640,000	2,251,000
Less: Billings to customers	934,000	6,101,000
CIEB	$  2,458,000	$  5,492,000
Number of projects in progress	13	20

As noted above, BIEC represents billings to customers in excess of revenues recognized. The $172,000 balance in this account at May 31, 2013 is in comparison to a $669,000 balance at the end of the prior year. The balance in this account fluctuates in the same manner and for the same reasons as the account "costs and estimated earnings in excess of billings", discussed above. Final delivery of product under these contracts is expected to occur during the next twelve months.

The year-end balances in this account are comprised of the following components:

	May 31, 2013	May 31, 2012
Billings to customers	$   256,000	$   1,107,000
Less:  Costs	71,000	328,000
Less: Estimated earnings	13,000	110,000
BIEC	$   172,000	$      669,000
Number of projects in progress	3	8

The Company's backlog of sales orders at May 31, 2013 is $13.1 million, down 25% from the backlog at the end of the prior year of $17.5 million. $3.2 million of the current backlog is on projects already in progress.

Accounts payable, at $1,210,000 as of May 31, 2013, is $2,152,000 less than the prior year-end. There is no specific reason for this fluctuation other than the normal payment cycle of vendor invoices combined with the decreased level of sales orders, resulting in decreased level of purchase orders from the Company to vendors for materials and services to produce our product.

Commission expense on applicable sales orders is recognized at the time revenue is recognized. The commission is paid following receipt of payment from the customers. Accrued commissions as of May 31, 2013 are $437,000. This is 31% less than the $631,000 accrued at the prior year-end. Commission expense related to long-term construction projects is recorded at the same time as revenue on the projects is recorded. This liability has decreased as the progress billings on the projects have been issued by the Company and paid by our customers. Considering that the net change in the balances of accounts receivable and CIEB is a decrease of $6,400,000 or 58% over the prior year end, it would be reasonable to expect that the balance in the accrued commissions would likewise be lower than the prior year. The Company expects the current accrued amount to be paid during the next twelve months.

Other accrued expenses of $1,736,000 decreased by 18% from the prior year of $2,117,000. This decrease is primarily due to a decrease in expenses related to contractual obligations on certain export sales.

Management believes that the Company's cash on hand, cash flows from operations and borrowing capacity under the bank line of credit will be sufficient to fund ongoing operations, capital improvements and share repurchases (if any) for the next twelve months.

CONSOLIDATED FINANCIAL STATEMENTS

May 31, 2013

[Lumsden & McCormick, LLP Letterhead]

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders

Taylor Devices, Inc.

We have audited the accompanying consolidated balance sheets of Taylor Devices, Inc. and Subsidiary as of May 31, 2013 and 2012, and the related consolidated statements of income, stockholders' equity, and cash flows for the years then ended. The Company's management is responsible for these financial statements. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Taylor Devices, Inc. and Subsidiary as of May 31, 2013 and 2012, and the results of its operations and its cash flows for the years then ended in conformity with accounting principles generally accepted in the United States of America.

TAYLOR DEVICES, INC. AND SUBSIDIARY

Notes to Consolidated Financial Statements

1. Summary of Significant Accounting Policies:

Nature of Operations:

Taylor Devices, Inc. (the Company) manufactures and sells a single group of very similar products that have many different applications for customers. These similar products are included in one of six categories; namely, Seismic Dampers, Fluidicshoks®, Crane and Industrial Buffers, Self-Adjusting Shock Absorbers, Liquid Die Springs, and Vibration Dampers for use in various types of machinery, equipment and structures, primarily to customers which are located throughout the United States and several foreign countries. The products are manufactured at the Company's sole operating facility in the United States where all of the Company's long-lived assets reside. Management does not track or otherwise account for sales broken down by these categories.

54% of the Company's 2013 revenue was generated from sales to customers in the United States and 41% was from sales to customers in Asia. Remaining sales were to customers in other countries in North America, Europe, South America and Australia.

39% of the Company's 2012 revenue was generated from sales to customers in the United States and 54% was from sales to customers in Asia. Remaining sales were to customers in other countries in North America, Europe, and South America.

Principles of Consolidation:

The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiary, Tayco Realty Corporation (Realty). All inter-company transactions and balances have been eliminated in consolidation.

Subsequent Events:

The Company has evaluated events and transactions for potential recognition or disclosure in the financial statements through the date the financial statements were issued.

Use of Estimates:

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Cash and Cash Equivalents:

The Company includes all highly liquid investments in money market funds in cash and cash equivalents on the accompanying balance sheets.

Cash and cash equivalents in financial institutions may exceed insured limits at various times during the year and subject the Company to concentrations of credit risk.

Accounts Receivable:

Accounts receivable are stated at an amount management expects to collect from outstanding balances. Management provides for probable uncollectible accounts through a charge to earnings and a credit to a valuation allowance based on its assessment of the current status of individual accounts. Balances that are still outstanding after management has used reasonable collection efforts are written off through a charge to the valuation allowance and a credit to accounts receivable.

Inventory:

Inventory is stated at the lower of average cost or market. Average cost approximates first-in, first-out cost.

Property and Equipment:

Property and equipment is stated at cost net of accumulated depreciation. Deprecation is provided primarily using the straight-line method for financial reporting purposes, and accelerated methods for income tax reporting purposes. Maintenance and repairs are charged to operations as incurred; significant improvements are capitalized.

Cash Value of Life Insurance:

Cash value of life insurance is stated at the surrender value of the contracts.

Revenue Recognition:

Sales are recognized when units are delivered or services are performed. Sales under fixed-price contracts are recorded as deliveries are made at the contract sales price of the units delivered. Sales under certain fixed-price contracts requiring substantial performance over several periods prior to commencement of deliveries, are accounted for under the percentage-of-completion method of accounting whereby revenues are recognized based on estimates of completion prepared on a ratio of cost to total estimated cost basis. Costs include all material and direct and indirect charges related to specific contracts. Other expenses are charged to operations as incurred. Total estimated costs for each of the contracts are estimated based on a combination of historical costs of manufacturing similar products and estimates or quotes from vendors for supplying parts or services towards the completion of the manufacturing process. Adjustments to cost estimates are made periodically, and losses expected to be incurred on contracts in progress are charged to operations in the period such losses are determined. If total costs calculated upon completion of the manufacturing process in the current period for a contract are more than the estimated total costs at completion used to calculate revenue in a prior period, then the revenue and profits in the current period will be lower than if the estimated costs used in the prior period calculation were equal to the actual total costs upon completion. In the fiscal year ended May 31, 2013, 58% of total revenue recognized was accounted for using the percentage-of-completion method of accounting while the remaining 42% of revenue was recorded as deliveries were made to our customers. In the fiscal year ended May 31, 2012, 77% of total revenue recognized was accounted for using the percentage-of-completion method of accounting while the remaining 23% of revenue was recorded as deliveries were made to our customers.

For financial statement presentation purposes, the Company nets progress billings against the total costs incurred on uncompleted contracts. The asset, "costs and estimated earnings in excess of billings," represents revenues recognized in excess of amounts billed. The liability, "billings in excess of costs and estimated earnings," represents billings in excess of revenues recognized.

Shipping and Handling Costs:

Shipping and handling costs are classified as a component of selling, general and administrative expenses. These costs for the fiscal year ended May 31, 2012 have been reclassified from cost of goods sold to selling, general and administrative expenses to conform with the presentation for 2013. The amount of these costs were $715,031 and $802,147 for the fiscal years ended May 31, 2013 and 2012, respectively.

Income Taxes:

The provision for income taxes provides for the tax effects of transactions reported in the financial statements regardless of when such taxes are payable. Deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the tax and financial statement basis of assets and liabilities. Deferred taxes are based on tax laws currently enacted with tax rates expected to be in effect when the taxes are actually paid or recovered.

The Company's practice is to recognize interest related to income tax matters in interest income / expense and to recognize penalties in selling, general and administrative expenses. The Company did not have any accrued interest or penalties included in its consolidated balance sheets at May 31, 2013 or 2012. The Company recorded no interest expense or penalties in its consolidated statements of income during the years ended May 31, 2013 and 2012.

The Company's tax returns for the fiscal tax years ended May 31, 2013 and 2012 will be subject to examination by federal and state tax authorities. During 2011, the Company’s tax returns for the years ended May 31, 2007 through 2010 were examined by Federal taxing authorities. The examinations resulted in no changes to the originally filed returns. Accordingly, no further examination of those tax returns is permitted. Additionally, the Company believes it is no longer subject to examination by state taxing authorities for fiscal years prior to May 31, 2010.

Sales Taxes:

Certain jurisdictions impose a sales tax on Company sales to nonexempt customers. The Company collects these taxes from customers and remits the entire amount as required by the applicable law. The Company excludes from revenues and expenses the tax collected and remitted.

Stock-Based Compensation:

The Company measures compensation cost arising from the grant of share-based payments to employees at fair value and recognizes such cost in income over the period during which the employee is required to provide service in exchange for the award. The stock-based compensation expense for the years ended May 31, 2013 and 2012 was $109,586 and $116,762.

New Accounting Standards:

In May 2011, the Financial Accounting Standards Board (FASB) issued an amendment to Accounting Standards Updates (ASU) Topic 820, Fair Value Measurement. This amendment improves the comparability of fair value measurements presented and disclosed in financial statements prepared in accordance with U.S. Generally Accepted Accounting Principals (GAAP) and International Financial Reporting Standards. Implementation of the amendment was required during interim and annual periods beginning after December 15, 2011. The adoption of this standard in 2012 did not have a significant effect on our results.

Other recently issued Accounting Standards Codification (ASC) guidance has either been implemented or are not significant to the Company.

Less allowance for obsolescence	1,264,849	1,353,208
	$    904,299	$    844,834

Maintenance and other inventory represent stock that is estimated to have a product life-cycle in excess of twelve-months. This stock represents certain items the Company is required to maintain for service of products sold, and items that are generally subject to spontaneous ordering.

This inventory is particularly sensitive to technical obsolescence in the near term due to its use in industries characterized by the continuous introduction of new product lines, rapid technological advances and product obsolescence. Therefore, management of the Company has recorded an allowance for potential inventory obsolescence.

The provision for potential inventory obsolescence was $180,000 for each of the years ended May 31, 2013 and 2012.

7. Short-Term Borrowings:

The Company has a credit facility with a $6,000,000 demand line of credit from a bank, with interest payable at the Company's option of 30, 60, 90 or 180 day LIBOR rate plus 2.5% or the bank's prime rate less .25%. The line is secured by accounts receivable, equipment, inventory, general intangibles, and a negative pledge of the Company's real property. This line of credit is subject to the usual terms and conditions applied by the bank and subject to renewal annually.

There is no amount outstanding under the line of credit at May 31, 2013. The total amount outstanding on the line of credit at May 31, 2012 was $258,000.

The Company uses a cash management facility under which the bank draws against the available line of credit to cover checks presented for payment on a daily basis. Outstanding checks under this arrangement totaled $113,095 and $226,413 as of May 31, 2013 and 2012. These amounts are included in accounts payable.

A breakdown of sales to these three general groups of customers is as follows:

	2013	2012
Construction	$14,105,072	$20,597,534
Aerospace / Defense	8,132,008	6,537,566
Industrial	2,492,505	1,871,712
	$24,729,585	$29,006,812

Sales to five customers approximated 52% (29%, 7%, 6%, 5% and 5%, respectively) of net sales for 2013. Sales to three customers approximated 49% (41%, 4% and 4%, respectively) of net sales for 2012.

10. Income Taxes:

	2013		2012
Current tax provision (benefit):
Federal	$  911,000		$  872,500
State	(1,000	)	3,500
	910,000		876,000
Deferred tax provision (benefit):
Federal	2,000		(125,700	)
State	-		(300	)
	2,000		(126,000	)
	$  912,000		$  750,000

A reconciliation of provision for income taxes at the statutory rate to income tax provision at the Company's effective rate is as follows:

	2013		2012
Computed tax provision at the expected statutory rate	$1,176,400		$1,002,700
State income tax - net of Federal tax benefit	(2,900	)	2,300
Tax effect of permanent differences:
Research tax credits	(213,000	)	(207,000	)
Other permanent differences	(29,800	)	(27,200	)
Other	(18,700	)	(20,800	)
	$   912,000		$   750,000
Effective income tax rate	26.4%		25.4%

Significant components of the Company's deferred tax assets and liabilities consist of the following:

	2013		2012
Deferred tax assets:
Allowance for doubtful receivables	$    14,400		$    14,400
Tax inventory adjustment	209,500		99,200
Allowance for obsolete inventory	465,400		495,200
Accrued vacation	60,200		64,500
Accrued commissions	4,000		9,300
Warranty reserve	126,300		101,000
Stock options issued for services	182,800		166,800
	1,062,600		950,400
Deferred tax liabilities:
Excess tax depreciation	(398,185	)	(283,985	)
Net deferred tax assets	$  664,415		$  666,415

Realization of the deferred tax assets is dependent on generating sufficient taxable income at the time temporary differences become deductible. The Company provides a valuation allowance to the extent that deferred tax assets may not be realized. A valuation allowance has not been recorded against the deferred tax assets since management believes it is more likely than not that the deferred tax assets are recoverable. The Company considers future taxable income and potential tax planning strategies in assessing the need for a potential valuation allowance. The amount of the deferred tax assets considered realizable however, could be reduced in the near term if estimates of future taxable income are reduced. The Company will need to generate approximately $3.1 million in taxable income in future years in order to realize the deferred tax assets recorded as of May 31, 2013 of $1,062,600.

The Company and its subsidiary file consolidated Federal and State income tax returns. As of May 31, 2013, the Company had State investment tax credit carryforwards of approximately $142,000 expiring through May 2019.

11. Earnings Per Common Share:

Basic earnings per common share is computed by dividing income available to common stockholders by the weighted-average common shares outstanding for the period. Diluted earnings per common share reflects the weighted-average common shares outstanding and dilutive potential common shares, such as stock options.

A reconciliation of weighted-average common shares outstanding to weighted-average common shares outstanding assuming dilution is as follows:

	2013	2012
Average common shares outstanding	3,310,514	3,269,252
Common shares issuable under stock option plans	46,778	34,363
Average common shares outstanding assuming dilution	3,357,292	3,303,615

12. Related Party Transactions:

The Company had no related party transactions for the years ended May 31, 2013 and 2012.

13. Employee Stock Purchase Plan:

In March 2004, the Company reserved 295,000 shares of common stock for issuance pursuant to a non-qualified employee stock purchase plan. Participation in the employee stock purchase plan is voluntary for all eligible employees of the Company. Purchase of common shares can be made by employee contributions through payroll deductions. At the end of each calendar quarter, the employee contributions will be applied to the purchase of common shares using a share value equal to the mean between the closing bid and ask prices of the stock on that date. These shares are distributed to the employees at the end of each calendar quarter or upon withdrawal from the plan. During the years ended May 31, 2013 and 2012, 1,359 ($8.39 to $8.98 price per share) and 1,477 ($5.625 to $10.19 price per share) common shares, respectively, were issued to employees. As of May 31, 2013, 231,380 shares were reserved for further issue.

14. Stock Option Plans:

In 2012, the Company adopted a stock option plan which permits the Company to grant both incentive stock options and non-qualified stock options. The incentive stock options qualify for preferential treatment under the Internal Revenue Code. Under this plan, 160,000 shares of common stock have been reserved for grant to key employees and directors of the Company and 16,750 shares have been granted as of May 31, 2013. Under the plan, the option price may not be less than the fair market value of the stock at the time the options are granted. Options vest immediately and expire ten years from the date of grant.

Using the Black-Scholes option pricing model, the weighted average estimated fair value of each option granted under the plan was $2.46 during 2013 and $2.90 during 2012. The pricing model uses the assumptions noted in the following table. Expected volatility is based on the historical volatility of the Company's stock. The risk-free interest rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of the grant. The expected life of options granted is derived from previous history of stock exercises from the grant date and represents the period of time that options granted are expected to be outstanding. The Company uses historical data to estimate option exercise and employee termination assumptions under the valuation model. The Company has never paid dividends on its common stock and does not anticipate doing so in the foreseeable future.

	2013	2012
Risk-free interest rate	2.21%	2.26%
Expected life in years	2.9	2.8
Expected volatility	75%	78%
Expected dividend yield	0%	0%

The following is a summary of stock option activity:

	Shares	Weighted Average Exercise Price	Intrinsic Value
Outstanding - May 31, 2011	229,000	$ 5.21	$ 173,570
Options granted	40,250	$ 8.99
Less: options exercised	105,500	$ 4.97
Outstanding - May 31, 2012	163,750	$ 6.30	$ 336,604
Options granted	44,500	$ 7.84
Less: options expired	1,500	-
Outstanding - May 31, 2013	206,750	$ 6.63	$ 377,891

We calculated intrinsic value for those options that had an exercise price lower than the market price of our common shares as of the balance sheet dates. The aggregate intrinsic value of outstanding options as of the end of each fiscal year is calculated as the difference between the exercise price of the underlying options and the market price of our common shares for the options that were in-the money at that date (181,750 at May 31, 2013 and 138,750 at May 31, 2012.) The Company's closing stock price was $8.07 and $9.55 as of May 31, 2013 and 2012. As of May 31, 2013, there are 143,250 options available for future grants under the 2012 stock option plan. $524,118 was received from the exercise of share options during the fiscal year ended May 31, 2012.

The following table summarizes information about stock options outstanding at May 31, 2013:

Outstanding and Exercisable

Exhibit 13

Taylor Devices, Inc. 2013 Annual Report

President's Letter

Dear Shareholder,

Fiscal year 2013 marked yet another successful year for Taylor Devices. Company sales totaled $24,729,585, second highest in our corporate history, as compared to $29,006,812 in 2012 and $20,906,306 in 2011. Operating income for 2013 was a record $3,466,662 as compared to $2,887,081 in 2012 and $1,482,491 in 2011. Net income also set a record at $2,547,794, compared to $2,198,931 in 2012 and $1,416,509 in 2011.

The lower sales volume in 2013 is due to a reduction in seismic and wind damper dollar volume. This was largely due to a surge in orders for these products in 2012, in the aftermath of major earthquakes in Asia. In comparison to the seismic damper sales reduction, aerospace product sales increased substantially for 2013, representing 33% of all sales compared to 23% in 2012. Industrial product sales also increased substantially to 10% of all sales vs. 6% in 2012. Order backlog at year’s end was $13.1 million, compared to $17.5 million in 2012, and $15 million in 2011. This reflects generally shorter lead times for aerospace and industrial products as compared to seismic and wind dampers.

Taylor Devices has always sought to stay on the leading edge of our markets by periodically introducing new and unique technology. In 2013, the Company developed and began testing on full-scale structures a modular wall panel with integral dampers in a patented configuration. This allows wood frame structures to be simply and easily upgraded with enhanced seismic protection. Similarly, the Company has filed for patents on a new concept to allow installation of seismic dampers into open storefronts, parking garages, and related structures that must retain open building bays and entrances. This new “Open Spaces Damping System” is unique in that the dampers and attachments are hidden along the top and sides of the bay, leaving the bay and the floor area entirely open. In addition to these new products being developed for the construction industry, the Company continues work on multiple applications for NASA’s next generation launch vehicle for manned space exploration. Hopefully there will also be “spin-offs” from the NASA programs to commercial applications.

This year’s Annual Report features a major wind damping project in New York City, the 40-story 250 West 55th Street Tower. This mixed-use building has nearly one million square feet of space and utilizes a unique control system, by the engineering firm ARUP, known as a “damped outrigger system.” This arrangement of dampers (patent pending, ARUP) works extremely well with Taylor Devices’ patented Metal Bellows Hermetically Sealed Dampers, which offer tens of millions of maintenance-free cycles of operation. With the damped outrigger system, the dampers are in continuous motion even under relatively low winds, and the Company’s metal bellows dampers offer superior performance under these long-term cyclic conditions.

Also featured in this report are Taylor Devices’ Precise Positioning Isolators that are used on numerous naval shipboard electronics and weapons systems. This product line has been in continuous production since 1963, with tens of thousands of these isolators used on the warships of many nations. Although the product concept is a half-century old, the isolator design has progressed through four generations technically, with patents obtained on each generation of the isolator.

As this Annual Report goes to print, renovation and upgrade work has been completed at the last and largest of the three buildings purchased by the Company in 2011 for expansion of our manufacturing operations. These buildings allow the Company to immediately gain operating efficiency due to the improved material flow and processing, plus they will accommodate for substantial increases in shipment volume in future years.

Sincerely,

TAYLOR DEVICES, INC.

Status Report from the Vice President

Richard G. Hill

This past year has been a challenging and satisfying time at Taylor Devices. Profits increased to record levels with the demand for both the Company's seismic products as well as orders for many non-standard products. The challenge was, would we be able to meet our customer's demands, and the satisfaction was seeing that we did.

At the same time, the Company was developing additional manufacturing space at a site close to the main plant that we now consider our North Campus located on Buffalo Bolt Way in North Tonawanda, New York. Two of three facilities at the North Campus have been brought on line and were in full production as of the end of the fiscal year. This additional capacity has freed us to move one of our finishing operations from a rented space, approximately five miles away, to the closer facilities at the North Campus. The third building, and perhaps the most exciting, will be the machining facility that we will be moving into this coming fall. The Company worked with the School of Engineering at the University at Buffalo in designing the internal layout of this building, giving us what we believe will be a state-of-the-art manufacturing facility. New equipment purchased during this past year, as well as the existing machining machines located at the South Campus plant on Tonawanda Island, will be moved into the facility. This move should be approximately a six week operation. The layout and space will improve the through-flow and efficiency of the Company. We look forward to the move and the capabilities this new space will give us.

The company made several purchases the past year of precision, state-of-the-art turning equipment and processing equipment that allows for a greater capacity at a reduced cost. It has allowed us to modify certain manufacturing processes, thus reducing cost and making the Company more competitive. We have also expanded our large unit test capacity to allow for a wider range of test parameters with minimal changes to the machine setup. This was done in response to requests we received from our customers and therefore, we can now offer these customers test capabilities that cannot be found anywhere else. It also reduces the time required in testing multiple units, which improves the Company's competitiveness. These changes, critical to the Company's ability to produce, are central to the Company remaining competitive in today's market.

The demand for individuals to work in manufacturing continues to grow as the available work force ages. In order to attract individuals to the Company we must remain competitive, offering an interesting, challenging career. We believe the changes to our facilities and the desire to work with and train Taylor employees can offer an individual that career. The Company will continue to offer these opportunities and expand its workforce, bringing additional employees in at all levels.

The upcoming year will offer challenges, and we believe we are well situated to meet those challenges. The past year was a great success and we look forward to the coming year.

Status Report from the Chief Financial Officer

Mark V. McDonough

In fiscal 2013, Taylor Devices, Inc. enjoyed our second highest sales level ever. Although the top line came in 15% under last year’s record sales level, at the bottom line we surpassed last year’s record high profits by 16%. A decrease in sales of seismic protection units in Asia was buffered by increases in sales to customers in the USA involved in the construction or retro-fitting of buildings and bridges as well as a 24% increase over last year in sales to customers in aerospace / defense. Sales to customers with industrial applications increased by 33% over last year’s level. Improvements in the gross margin absorbed most of the sales decrease and savings in selling expenses helped push operating income 20% higher than last year’s level. The record high net income translated to earnings per share of 76 cents for fiscal 2013 compared to 67 cents for the prior year.

The Company’s backlog of sales orders at May 31, 2013 is $13.1 million, down 25% from the backlog at the end of the prior year. 59% is for customers with aerospace / defense applications and 38% will go to customers with construction applications. 58% is for domestic customers while 37% will be shipped to Asia. We are encouraged by new sales order activity in the early stages of the new fiscal year.

We are now fully into XBRL reporting as required by the SEC. This new tool for investors allows them to more thoroughly and efficiently analyze Taylor Devices, Inc. and other entities to assist with their investment decisions. We will continue to work with our advisors to keep abreast of changes in the regulations and to remain in compliance with them in order to ensure that accurate, reliable financial and business information is provided to investors and other users of this annual report and our interim reports.

Aerospace / Defense Products Report

Paul L. Tuttobene

Sales in 2013 exceeded expectation with a 24% increase over 2012, more than making-up for last year’s 10% decline. In spite of the so called “sequester,” Taylor Devices is still generating new business in the U.S. and in foreign military markets.

Though many U.S. military programs have slowed in 2013 due to budget cuts, Taylor Devices has been fortunate to have existing programs, like the Spade Damper for the M777 Light Weight Howitzer and our continued support of the Virginia Class Submarine program adding to our backlog of orders. Also, Taylor Devices has been able to secure orders on foreign missile defense programs, insulating Taylor Devices from U.S. budget cuts. Several of our Middle-Eastern and Asian allies are working to develop and procure these advanced missile defense systems which, in turn, will result in orders for Taylor Devices in the near future.

Two other orders have far reaching and long term promise for Taylor Devices’ Military/Aerospace sales - one being the development contract for the next generation manned spacecraft. Taylor Devices has always been seen as a valued partner in NASA’s Hi-Tech supply-chain. Our involvement in the manned space program dates back to the Apolloprogram of the early 1960s and we’re looking forward to continuing this special partnership. The second is the refueling boom deceleration system on the new KC-46 air-tanker program for the U.S. Air Force. Taylor Devices has been supplying this type of equipment for the Air Force since the late 1970s. With this new contract, Taylor Devices will supply boom deceleration systems for the first (18) KC-46 Air-Tankers through 2017, with a planned total of 179 aircraft to be produced.

Other highlights this year include the 50 Caliber Machine Gun Mount Recoil Buffer for NATO, C-17 Transport aircraft engine trailer suspension struts, and smart bomb control fin dampers to name a few.

Though Taylor Devices is anticipating cuts in the U.S. military budget, we are confident that the combination of product mix, technological advantage, and program selection will keep our military sales robust for years to come.

Industrial Products Report

Craig W. Winters

Robert H. Schneider

While the U.S. economy progresses along in another recession and the world economies continue their uncertain progress, the overall sales of Taylor Devices’ Industrial Product Lines for FY13 have performed very well, even despite the phenomenal year we had in FY12, and the probability that we would not match that year in sales volume during FY13. While FY12 was an incredible year, it had a profound effect on our future outlook for sales because the surge in work (that year) resulted in our lead-times extending beyond normal and expected levels of our seismic dampers for upcoming projects. This caused many engineers and owners to choose traditional strengthening or low-technology alternatives to our products, to suit their desired schedules on new construction projects or retrofits. To improve our lead-time and get back-on track, we implemented a dual strategy to effectively regain future projects and clients. One was to expand our factory, doubling the size of our previously streamlined facility to allow more space for assembly and finishing of products, while the other, more important improvement was to appropriately bolster our inventory of materials and parts to better support sales and delivery of our seismic dampers. This combination has lead to a substantial improvement in our delivery time capability, which has translated into more engineers designing our products into their bridge and building structures and other applications, allowing us to quickly realize the fruits of our labor. Without this inventory of readily available materials and parts allowing faster delivery times, our sales would not have been as solid during FY13. Our plan is to continue this trend to further improve our ability to meet the ever-faster turnaround times desired by clients in the niche market of seismic dampers, where customized products are necessary to suit the characteristics of the structure, the local earthquake, or wind content, and the soil/foundation systems present.

We continue to obtain new orders domestically and throughout the world for our Fluid Viscous Dampers and specialized devices used for structural protection against earthquakes, wind vibration, and pedestrian movements, while our Crane Buffer sales and other industrial product sales have remained solid, but relatively flat.

During FY13, Taylor Devices was awarded contracts to supply Fluid Viscous Dampers for the following significant projects: The new Haramain High Speed Railway in Saudi Arabia – connecting Mecca and Jeddah, a Boeing Airplane Hanger Facility in Everett, Washington, a residential home in California, the Haneda Airport (Tokyo International Airport) in Japan, the Bnei Zion Hospital in Haifa, Israel, a BART station building retrofit in Pleasant Hill, California, an Apple store, in the Stonestown Galleria Mall, San Francisco, California, and an athletic club in Pismo Beach, California. Many other seismic damper projects were also received in FY13 from multiple locations in North America, Europe, Asia, and South America for retrofit and new construction of numerous commercial, residential, and micro-chip fabrication facility projects, along with a number of new and retrofit bridge projects in these areas.

Our backlog of seismic damper work for FY14 appears appropriate, based on the faster turn-around times desired by clients and our ability to meet these demands. A number of projects are currently in the works and we are ready to support these needs. This gives us cautious optimism for the Industrial Product Lines maintaining resilient sales through FY14. We continue to monitor the domestic and global economies and strive to maintain our flexibility to meet the various needs of our clients.

He has been employed by Taylor Devices, Inc. since 1971, and was appointed President in April 1991. Mr. Taylor previously was President of Tayco Developments, Inc., an affiliate of Taylor Devices, Inc. that was subsequently acquired by merger in 2008, where he had been employed since 1966, and was appointed President in 1991. He is inventor or co-inventor on 32 patents in the fields of energy management, hydraulics and shock isolation.

Mr. Taylor is widely published within the shock and vibration community. His technical papers have been published by the American Society of Civil Engineers, the Applied Technology Council, the Association of Iron and Steel Engineers, the Journal of Shock and Vibration, the National Fluid Power Foundation, the National Science Foundation, the New York State Science and Technology Foundation, the Shock and Vibration Symposium, the Society of Automotive Engineers, the U.S. Air Force and the U.S. Marine Corps. Since 1988, Mr. Taylor has hosted internship programs for engineering students, affiliated as an industrial sponsor with the State University of New York at Buffalo, the Erie County State of New York Board of Co-operative Educational Services, and the North Tonawanda, New York Public School System.

Since 1991, Mr. Taylor has participated in research projects in the field of earthquake protection, in association with the University at Buffalo’s Civil, Structural and Environmental Engineering Department and the Multidisciplinary Center for Extreme Events Research. As a result of this research, military technology from the Cold War era is now being used worldwide for seismic and high wind protection of commercial building and bridge structures.

NEWS FROM TAYLOR DEVICES, INC.

SHAREHOLDER LETTER, SUMMER 2013

THIS NEWSLETTER IS DIRECTED TO ALL SHAREHOLDERS OF TAYLOR DEVICES. WE HOPE THAT IT WILL GENERATE INTEREST IN THE COMPANY, PLUS PROVIDE CURRENT FINANCIAL AND PROJECT INFORMATION. COPIES OF THIS NEWSLETTER WILL ALSO BE CIRCULATED TO SHAREHOLDERS WHO HAVE SHARES IN BROKERAGE ACCOUNTS.

ITEM: FINANCIAL RESULTS

Taylor Devices completed its 2012-2013 fiscal year on May 31, 2013, setting an all-time record for net income. Sales for 2013 were $24,729,585, down from a record level of $29,006,812 in 2012. Record net income was $2,547,794 for 2013, up 16% from the previous record net income of $2,198,931 in 2012.

Sales and income reflect increased shipments of aerospace and defense products for the year, as compared to a reduction in sales of seismic products. However, the higher seismic products sales in the 2012 fiscal year reflected a surge in demand from Asia as a result of heavy damage from the March 2011 Tonoku earthquake in Japan.

Taylor Devices= firm order backlog at year-end was $13.1 million, compared to $17.5 million at the end of 2012.

ITEM: NEW ORDERS -- AEROSPACE / DEFENSE

n Machined Springs for Military Aircraft -- Follow-on orders were received for custom modular machined spring assemblies used in the cargo loading systems of military transport aircraft. The initial buy for this program was announced in the Spring 2013 Newsletter. Additional follow-on orders are expected.

n Shipboard Navigation System Isolators -- Orders were received from multiple customers for these products, to be used on a total of 56 naval navigation systems, each of which uses six Taylor Devices' Tension-Compression Shock Isolators.

n Military Aircraft Seating Shock Absorbers -- This is a new product which has gone from a limited number of prototypes to low-rate production. Contract restrictions prevent additional information from being presented here.

n Military Vehicle Blast Resistant Seat Shock Absorbers -- This is a new product which has rapidly transitioned from demonstration and test units to low-rate production. However, the basic research and development effort by the Company to fully develop this product has been on-going for more than ten years. In many cases, the vehicles involved required major design changes to prevent the vehicle body from rupturing due to the under-vehicle detonation of a land mine or improvised explosive device (IED). Once these changes were accomplished, the next step in reducing combat deaths and injury to the vehicle occupants involved adding an energy absorbing occupant seat that can limit decelerations to the occupants, under both the initial violent high-velocity blast, plus several subsequent and equally violent cycles of vehicle motion just after detonation. The Company's research effort borrowed heavily on previous human factors knowledge gained in engineering, designing, and producing the shock absorbers for the STIDD-Taylor Energy Absorbing Seat used by the U.S. Navy on their high-speed Mark-V Seal delivery boats. The STIDD-Taylor seats have been in service for several years, with substantial reduction in injury to naval and special forces personnel.

The challenge for the new project involved producing a shock absorber for land vehicle seats that would respond very quickly to a mine or IED detonation. The shock absorber is required to begin limiting decelerations to the occupant within less than one ten-thousandth of a second. After the instant of detonation, the shock absorber's output must follow a complex path function-based on shock absorber stroke, instantaneous velocity, and occupant accelerations/decelerations. This propriety path function, developed by the Company after several years of research, is critical. The occupant's head and neck must experience a deceleration profile which will initially compress the head and neck into the shoulders and upper body muscles prior to the shock absorber providing maximum deceleration forces to the hips and torso. This is necessary to reduce chances of fatalities from brain damage or spinal fracture from whiplash loadings.

Extensive lab testing on the new shock absorbers was followed by full-scale live-fire testing this year at Government facilities. These tests were extremely successful, with the end result being a low-rate production order for 500 of the new shock absorbers. If the new seating system proves successful in actual combat operations, then additional orders are expected to be forthcoming.

ITEM: UPDATE RESEARCH FOR SOFT STORY BUILDINGS

In the Spring 2013 Newsletter, the Company announced that it is participating in a research program developing seismic protection systems for both commercial buildings and residences having a so-called "soft story." In this type of building, the first story walls are cut away to allow for storefront windows or vehicle parking. In the event of a major earthquake, this type of structure is prone to major damage or collapse at the soft story area. Thus far, the research has generated a new series of products specifically designed to protect soft story buildings where it is not possible to place dampers across the open bays without blocking the view or limiting ingress/egress to the building. The Company believes these new products have a large potential market. As a result, Taylor Devices has elected to file for a patent(s) on the new technology before any public disclosure is made via university laboratory testing.

ITEM: NEXT SHAREHOLDER MAILING

Our next Shareholder mailing will be the Notice of Annual Meeting of Shareholders. You should be receiving your mailing in September.

ITEM: SPECIAL NOTICE

On July 10, 2013, the Northrop-Grumman X47-B Drone Aircraft made aviation history with the first landing of an unmanned aircraft on an aircraft carrier. Taylor Devices designed and manufactured the arresting hook energy absorbers and centering spring-dampers inside the aircraft used to absorb the shock loadings when the X47-B's tail hook engages the arresting cable on the aircraft carrier. Although the X47-B is an experimental aircraft, the U.S. Navy is most interested in a production carrier aircraft with similar capabilities for future combat and air support missions. The X47-B has a 62 foot wing span and a maximum take-off weight of more than 20 tons.

54% of the Company's 2013 revenue was generated from sales to customers in the United States and 41% was from sales to customers in Asia. Remaining sales were to customers in other countries in North America, Europe, South America and Australia.

39% of the Company's 2012 revenue was generated from sales to customers in the United States and 54% was from sales to customers in Asia. Remaining sales were to customers in other countries in North America, Europe, and South America.

Principles of Consolidation:

Principles of Consolidation:

The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiary, Tayco Realty Corporation (Realty). All inter-company transactions and balances have been eliminated in consolidation.

Subsequent Events:

Subsequent Events:

The Company has evaluated events and transactions for potential recognition or disclosure in the financial statements through the date the financial statements were issued.

Use of Estimates:

Use of Estimates:

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Cash and Cash Equivalents:

Cash and Cash Equivalents:

The Company includes all highly liquid investments in money market funds in cash and cash equivalents on the accompanying balance sheets.

Cash and cash equivalents in financial institutions may exceed insured limits at various times during the year and subject the Company to concentrations of credit risk.

Accounts Receivable:

Accounts Receivable:

Accounts receivable are stated at an amount management expects to collect from outstanding balances. Management provides for probable uncollectible accounts through a charge to earnings and a credit to a valuation allowance based on its assessment of the current status of individual accounts. Balances that are still outstanding after management has used reasonable collection efforts are written off through a charge to the valuation allowance and a credit to accounts receivable.

Inventory:

Inventory:

Inventory is stated at the lower of average cost or market. Average cost approximates first-in, first-out cost.

Property and Equipment:

Property and Equipment:

Property and equipment is stated at cost net of accumulated depreciation. Deprecation is provided primarily using the straight-line method for financial reporting purposes, and accelerated methods for income tax reporting purposes. Maintenance and repairs are charged to operations as incurred; significant improvements are capitalized.

Cash Value of Life Insurance:

Cash Value of Life Insurance:

Cash value of life insurance is stated at the surrender value of the contracts.

Revenue Recognition:

Revenue Recognition:

Sales are recognized when units are delivered or services are performed. Sales under fixed-price contracts are recorded as deliveries are made at the contract sales price of the units delivered. Sales under certain fixed-price contracts requiring substantial performance over several periods prior to commencement of deliveries, are accounted for under the percentage-of-completion method of accounting whereby revenues are recognized based on estimates of completion prepared on a ratio of cost to total estimated cost basis. Costs include all material and direct and indirect charges related to specific contracts. Other expenses are charged to operations as incurred. Total estimated costs for each of the contracts are estimated based on a combination of historical costs of manufacturing similar products and estimates or quotes from vendors for supplying parts or services towards the completion of the manufacturing process. Adjustments to cost estimates are made periodically, and losses expected to be incurred on contracts in progress are charged to operations in the period such losses are determined. If total costs calculated upon completion of the manufacturing process in the current period for a contract are more than the estimated total costs at completion used to calculate revenue in a prior period, then the revenue and profits in the current period will be lower than if the estimated costs used in the prior period calculation were equal to the actual total costs upon completion. In the fiscal year ended May 31, 2013, 58% of total revenue recognized was accounted for using the percentage-of-completion method of accounting while the remaining 42% of revenue was recorded as deliveries were made to our customers. In the fiscal year ended May 31, 2012, 77% of total revenue recognized was accounted for using the percentage-of-completion method of accounting while the remaining 23% of revenue was recorded as deliveries were made to our customers.

For financial statement presentation purposes, the Company nets progress billings against the total costs incurred on uncompleted contracts. The asset, "costs and estimated earnings in excess of billings," represents revenues recognized in excess of amounts billed. The liability, "billings in excess of costs and estimated earnings," represents billings in excess of revenues recognized.

Shipping and Handling Costs:

Shipping and Handling Costs:

Shipping and handling costs are classified as a component of selling, general and administrative expenses. These costs for the fiscal year ended May 31, 2012 have been reclassified from cost of goods sold to selling, general and administrative expenses to conform with the presentation for 2013. The amount of these costs were $715,031 and $802,147 for the fiscal years ended May 31, 2013 and 2012, respectively.

Income Taxes:

Income Taxes:

The provision for income taxes provides for the tax effects of transactions reported in the financial statements regardless of when such taxes are payable. Deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the tax and financial statement basis of assets and liabilities. Deferred taxes are based on tax laws currently enacted with tax rates expected to be in effect when the taxes are actually paid or recovered.

The Company's practice is to recognize interest related to income tax matters in interest income / expense and to recognize penalties in selling, general and administrative expenses. The Company did not have any accrued interest or penalties included in its consolidated balance sheets at May 31, 2013 or 2012. The Company recorded no interest expense or penalties in its consolidated statements of income during the years ended May 31, 2013 and 2012.

The Company's tax returns for the fiscal tax years ended May 31, 2013 and 2012 will be subject to examination by federal and state tax authorities. During 2011, the Company’s tax returns for the years ended May 31, 2007 through 2010 were examined by Federal taxing authorities. The examinations resulted in no changes to the originally filed returns. Accordingly, no further examination of those tax returns is permitted. Additionally, the Company believes it is no longer subject to examination by state taxing authorities for fiscal years prior to May 31, 2010.

Sales Taxes:

Sales Taxes:

Certain jurisdictions impose a sales tax on Company sales to nonexempt customers. The Company collects these taxes from customers and remits the entire amount as required by the applicable law. The Company excludes from revenues and expenses the tax collected and remitted.

Stock-Based Compensation:

Stock-Based Compensation:

The Company measures compensation cost arising from the grant of share-based payments to employees at fair value and recognizes such cost in income over the period during which the employee is required to provide service in exchange for the award. The stock-based compensation expense for the years ended May 31, 2013 and 2012 was $109,586 and $116,762.

New Accounting Standards:

New Accounting Standards:

In May 2011, the Financial Accounting Standards Board (FASB) issued an amendment to Accounting Standards Updates (ASU) Topic 820, Fair Value Measurement. This amendment improves the comparability of fair value measurements presented and disclosed in financial statements prepared in accordance with U.S. Generally Accepted Accounting Principals (GAAP) and International Financial Reporting Standards. Implementation of the amendment was required during interim and annual periods beginning after December 15, 2011. The adoption of this standard in 2012 did not have a significant effect on our results.

Other recently issued Accounting Standards Codification (ASC) guidance has either been implemented or are not significant to the Company.

Less allowance for obsolescence	1,264,849	1,353,208
Maintenance and other inventory, net	904,299	844,834

Maintenance and other inventory represent stock that is estimated to have a product life-cycle in excess of twelve-months. This stock represents certain items the Company is required to maintain for service of products sold, and items that are generally subject to spontaneous ordering.

This inventory is particularly sensitive to technical obsolescence in the near term due to its use in industries characterized by the continuous introduction of new product lines, rapid technological advances and product obsolescence. Therefore, management of the Company has recorded an allowance for potential inventory obsolescence.

The provision for potential inventory obsolescence was $180,000 for the year ended May 31, 2013 and $180,000 for the year ended 2012.

Net deferred tax assets	664,415		666,415

Realization of the deferred tax assets is dependent on generating sufficient taxable income at the time temporary differences become deductible. The Company provides a valuation allowance to the extent that deferred tax assets may not be realized. A valuation allowance has not been recorded against the deferred tax assets since management believes it is more likely than not that the deferred tax assets are recoverable. The Company considers future taxable income and potential tax planning strategies in assessing the need for a potential valuation allowance. The amount of the deferred tax assets considered realizable however, could be reduced in the near term if estimates of future taxable income are reduced. The Company will need to generate approximately $3,100,000 in taxable income in future years in order to realize the deferred tax assets recorded as of May 31, 2013 of $1,062,600.

The Company and its subsidiary file consolidated Federal and State income tax returns. As of May 31, 2013, the Company had State investment tax credit carryforwards of approximately $142,000 expiring through May 2019.

Accounting Policies [Abstract]

Significant Accounting Policies Note

1. Summary of Significant Accounting Policies:

Nature of Operations:

Taylor Devices, Inc. (the Company) manufactures and sells a single group of very similar products that have many different applications for customers. These similar products are included in one of six categories; namely, Seismic Dampers, Fluidicshoks®, Crane and Industrial Buffers, Self-Adjusting Shock Absorbers, Liquid Die Springs, and Vibration Dampers for use in various types of machinery, equipment and structures, primarily to customers which are located throughout the United States and several foreign countries. The products are manufactured at the Company's sole operating facility in the United States where all of the Company's long-lived assets reside. Management does not track or otherwise account for sales broken down by these categories.

54% of the Company's 2013 revenue was generated from sales to customers in the United States and 41% was from sales to customers in Asia. Remaining sales were to customers in other countries in North America, Europe, South America and Australia.

39% of the Company's 2012 revenue was generated from sales to customers in the United States and 54% was from sales to customers in Asia. Remaining sales were to customers in other countries in North America, Europe, and South America.

Principles of Consolidation:

The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiary, Tayco Realty Corporation (Realty). All inter-company transactions and balances have been eliminated in consolidation.

Subsequent Events:

The Company has evaluated events and transactions for potential recognition or disclosure in the financial statements through the date the financial statements were issued.

Use of Estimates:

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Cash and Cash Equivalents:

The Company includes all highly liquid investments in money market funds in cash and cash equivalents on the accompanying balance sheets.

Cash and cash equivalents in financial institutions may exceed insured limits at various times during the year and subject the Company to concentrations of credit risk.

Accounts Receivable:

Accounts receivable are stated at an amount management expects to collect from outstanding balances. Management provides for probable uncollectible accounts through a charge to earnings and a credit to a valuation allowance based on its assessment of the current status of individual accounts. Balances that are still outstanding after management has used reasonable collection efforts are written off through a charge to the valuation allowance and a credit to accounts receivable.

Inventory:

Inventory is stated at the lower of average cost or market. Average cost approximates first-in, first-out cost.

Property and Equipment:

Property and equipment is stated at cost net of accumulated depreciation. Deprecation is provided primarily using the straight-line method for financial reporting purposes, and accelerated methods for income tax reporting purposes. Maintenance and repairs are charged to operations as incurred; significant improvements are capitalized.

Cash Value of Life Insurance:

Cash value of life insurance is stated at the surrender value of the contracts.

Revenue Recognition:

Sales are recognized when units are delivered or services are performed. Sales under fixed-price contracts are recorded as deliveries are made at the contract sales price of the units delivered. Sales under certain fixed-price contracts requiring substantial performance over several periods prior to commencement of deliveries, are accounted for under the percentage-of-completion method of accounting whereby revenues are recognized based on estimates of completion prepared on a ratio of cost to total estimated cost basis. Costs include all material and direct and indirect charges related to specific contracts. Other expenses are charged to operations as incurred. Total estimated costs for each of the contracts are estimated based on a combination of historical costs of manufacturing similar products and estimates or quotes from vendors for supplying parts or services towards the completion of the manufacturing process. Adjustments to cost estimates are made periodically, and losses expected to be incurred on contracts in progress are charged to operations in the period such losses are determined. If total costs calculated upon completion of the manufacturing process in the current period for a contract are more than the estimated total costs at completion used to calculate revenue in a prior period, then the revenue and profits in the current period will be lower than if the estimated costs used in the prior period calculation were equal to the actual total costs upon completion. In the fiscal year ended May 31, 2013, 58% of total revenue recognized was accounted for using the percentage-of-completion method of accounting while the remaining 42% of revenue was recorded as deliveries were made to our customers. In the fiscal year ended May 31, 2012, 77% of total revenue recognized was accounted for using the percentage-of-completion method of accounting while the remaining 23% of revenue was recorded as deliveries were made to our customers.

For financial statement presentation purposes, the Company nets progress billings against the total costs incurred on uncompleted contracts. The asset, "costs and estimated earnings in excess of billings," represents revenues recognized in excess of amounts billed. The liability, "billings in excess of costs and estimated earnings," represents billings in excess of revenues recognized.

Shipping and Handling Costs:

Shipping and handling costs are classified as a component of selling, general and administrative expenses. These costs for the fiscal year ended May 31, 2012 have been reclassified from cost of goods sold to selling, general and administrative expenses to conform with the presentation for 2013. The amount of these costs were $715,031and $802,147 for the fiscal years ended May 31, 2013 and 2012, respectively.

Income Taxes:

The provision for income taxes provides for the tax effects of transactions reported in the financial statements regardless of when such taxes are payable. Deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the tax and financial statement basis of assets and liabilities. Deferred taxes are based on tax laws currently enacted with tax rates expected to be in effect when the taxes are actually paid or recovered.

The Company's practice is to recognize interest related to income tax matters in interest income / expense and to recognize penalties in selling, general and administrative expenses. The Company did not have any accrued interest or penalties included in its consolidated balance sheets at May 31, 2013 or 2012. The Company recorded no interest expense or penalties in its consolidated statements of income during the years ended May 31, 2013 and 2012.

The Company's tax returns for the fiscal tax years ended May 31, 2013 and 2012 will be subject to examination by federal and state tax authorities. During 2011, the Company’s tax returns for the years ended May 31, 2007 through 2010 were examined by Federal taxing authorities. The examinations resulted in no changes to the originally filed returns. Accordingly, no further examination of those tax returns is permitted. Additionally, the Company believes it is no longer subject to examination by state taxing authorities for fiscal years prior to May 31, 2010.

Sales Taxes:

Certain jurisdictions impose a sales tax on Company sales to nonexempt customers. The Company collects these taxes from customers and remits the entire amount as required by the applicable law. The Company excludes from revenues and expenses the tax collected and remitted.

Stock-Based Compensation:

The Company measures compensation cost arising from the grant of share-based payments to employees at fair value and recognizes such cost in income over the period during which the employee is required to provide service in exchange for the award. The stock-based compensation expense for the years ended May 31, 2013 and 2012 was $109,586 and $116,762.

New Accounting Standards:

In May 2011, the Financial Accounting Standards Board (FASB) issued an amendment to Accounting Standards Updates (ASU) Topic 820, Fair Value Measurement. This amendment improves the comparability of fair value measurements presented and disclosed in financial statements prepared in accordance with U.S. Generally Accepted Accounting Principals (GAAP) and International Financial Reporting Standards. Implementation of the amendment was required during interim and annual periods beginning after December 15, 2011. The adoption of this standard in 2012 did not have a significant effect on our results.

Other recently issued Accounting Standards Codification (ASC) guidance has either been implemented or are not significant to the Company.

Stock option plans

14. Stock Option Plans:

In 2012, the Company adopted a stock option plan which permits the Company to grant both incentive stock options and non-qualified stock options. The incentive stock options qualify for preferential treatment under the Internal Revenue Code. Under this plan, 160,000 shares of common stock have been reserved for grant to key employees and directors of the Company and 16,750 shares have been granted as of May 31, 2013. Under the plan, the option price may not be less than the fair market value of the stock at the time the options are granted. Options vest immediately and expire ten years from the date of grant.

Using the Black-Scholes option pricing model, the weighted average estimated fair value of each option granted under the plan was $2.46 during 2013 and $2.90 during 2012. The pricing model uses the assumptions noted in the following table. Expected volatility is based on the historical volatility of the Company's stock. The risk-free interest rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of the grant. The expected life of options granted is derived from previous history of stock exercises from the grant date and represents the period of time that options granted are expected to be outstanding. The Company uses historical data to estimate option exercise and employee termination assumptions under the valuation model. The Company has never paid dividends on its common stock and does not anticipate doing so in the foreseeable future.

	2013	2012
Risk-free interest rate	2.21%	2.26%
Expected life in years	2.9	2.8
Expected volatility	75%	78%
Expected dividend yield	0%	0%

We calculated intrinsic value for those options that had an exercise price lower than the market price of our common shares as of the balance sheet dates. The aggregate intrinsic value of outstanding options as of the end of each fiscal year is calculated as the difference between the exercise price of the underlying options and the market price of our common shares for the options that were in-the money at that date (181,750 at May 31, 2013 and 138,750 at May 31, 2012.) The Company's closing stock price was $8.07 and $9.55 as of May 31, 2013 and 2012. As of May 31, 2013, there are 143,250 options available for future grants under the 2012 stock option plan. $524,118 was received from the exercise of share options during the fiscal year ended May 31, 2012.
