Note 4—Balance Sheet Information

Cash and Cash Equivalents

Cash and cash equivalents include cash and certain highly liquid investments. Highly liquid investments with maturities of three months or less when purchased may be classified as cash equivalents. Such items may include liquid money market accounts, U.S. treasuries, government agency securities and corporate debt. The investments that are classified as cash equivalents are carried at cost, which approximates fair value.

During the three months ended March 31, 2014 and 2013, available-for-sale securities were liquidated for total proceeds of $32.0 million and $101.2 million, respectively. For the three months ended March 31, 2014 there were no realized gains on these liquidations, which were all maturities of investments. For the three months ended March 31, 2013 the gross realized gains on these sales were $0.1 million. The cost of securities sold is based on specific identification.

The table below shows the fair value of short-term investments that have been in an unrealized loss position for less than 12 months (in thousands):

	March 31, 2014
	Less than 12 months					Total
	Estimated Fair Value		Gross Unrealized Losses			Estimated Fair Value		Gross Unrealized Losses
Corporate debt	$	25,916	$	(13	)	$	25,916	$	(13	)
Total	$	25,916	$	(13	)	$	25,916	$	(13	)

	December 31, 2013
	Less than 12 months					Total
	Estimated Fair Value		Gross Unrealized Losses			Estimated Fair Value		Gross Unrealized Losses
Corporate debt	$	37,654	$	(36	)	$	37,654	$	(36	)
U. S. treasuries	29,068		(1		)	29,068		(1		)
Total	$	66,722	$	(37	)	$	66,722	$	(37	)

We did not hold any short-term investments that have been in an unrealized loss position for 12 months or longer for the periods noted in the tables above.

The Company regularly reviews its investment portfolio to identify and evaluate investments that have indications of possible impairment. Factors considered in determining whether an unrealized loss was considered to be temporary or other-than-temporary and therefore impaired include: the length of time and extent to which fair value has been lower than the cost basis; the financial condition and near-term prospects of the investee; and whether it is more likely than not that the Company will be required to sell the security prior to recovery. The Company believes the gross unrealized losses on the Company’s short-term investments as of March 31, 2014 and December 31, 2013 were temporary in nature and therefore did not recognize any impairment.

Contractual maturities of available-for-sale debt securities are as follows (in thousands):

	March 31, 2014
	Estimated Fair Value
Due in one year or less	$	207,913
Due in 1–2 years	47,621
Due in 2–3 years	11,868
Total available-for-sale securities	$	267,402

Actual maturities may differ from contractual maturities because some borrowers have the right to call or prepay obligations with or without call or prepayment penalties.

Restricted Cash

As of March 31, 2014 and December 31, 2013, restricted cash was $0.8 million and $2.7 million, respectively, which serves as collateral for bank guarantees that provide financial assurance that the Company will fulfill certain customer obligations. This cash is held in custody by the issuing bank and is restricted as to withdrawal or use while the related bank guarantees are outstanding.

Accounts Receivable, Net

Accounts receivable are presented net of allowance for doubtful accounts of $2.7 million and $2.4 million as of March 31, 2014 and December 31, 2013, respectively. We evaluate the collectability of accounts receivable based on a combination of factors. In cases where we become aware of circumstances that may impair a customer’s ability to meet its financial obligations subsequent to the original sale, we will record an allowance against amounts due, and thereby reduce the net recognized receivable to the amount the we reasonably believes will be collected. For all other customers, we recognize an allowance for doubtful accounts based on the length of time the receivables are past due and consideration of other factors such as industry conditions, the current business environment and its historical experience.

Inventories

Inventories are stated at the lower of cost (principally first-in, first-out) or market. Inventories consist of (in thousands):

Property, Plant and Equipment, Net

As of March 31, 2014, we are holding $5.8 million of tools, that were previously used in our laboratories, for sale. These tools are carried in machinery and equipment, as a component of property, plant and equipment, net in our Condensed Consolidated Balance Sheets. These tools are the same type of tools we sell to our customers in the ordinary course of our business. During the three months ended March 31, 2014, we converted and sold $1.4 million of tools that we had previously used in our laboratories as Veeco Certified Equipment at an aggregate selling price of $2.3 million which is included in revenue in our Condensed Consolidated Statements of Operations.

Cost Method Investment

On September 28, 2010, we completed a $3.0 million investment in a rapidly developing organic light emitting diode (also known as OLED) equipment company (the “Investment”). We invested an additional $10.3 million and $1.2 million in the Investment during 2012 and 2011, respectively. In 2013, we invested an additional $2.4 million in the Investment in the form of bridge notes bearing 4% interest. The bridge notes are payable in equity at the time of a liquidity event or a qualifying equity investment round, otherwise they are payable in cash one year from the date of issuance. During the three months ended March 31, 2014, we invested an additional $0.2 million in the Investment in the form of additional bridge notes. Subsequent to quarter end, we invested an additional $0.6 million in the bridge notes. As of March 31, 2014 and December 31, 2013, we have a 15.4% ownership of the preferred shares, and effectively hold a 11.0% ownership interest of the total company. Since we do not exert significant influence on the Investment, this investment is treated under the cost method in accordance with applicable accounting guidance. This investment is recorded in other assets in our Condensed Consolidated Balance Sheets as of March 31, 2014 and December 31, 2013.

Customer Deposits and Deferred Revenue

As of March 31, 2014 and December 31, 2013, we had customer deposits of $31.3 million and $27.5 million, respectively recorded as a component of customer deposits and deferred revenue.

Accrued Warranty

We estimate the costs that may be incurred under the warranties we provide and record a liability in the amount of such costs at the time the related revenue is recognized. Factors that affect our warranty liability include product failure rates, material usage and labor costs incurred in correcting product failures during the warranty period. This accrual is recorded in accrued expenses and other current liabilities in our Condensed Consolidated Balance Sheets. We periodically assess the adequacy of our recognized warranty liability and adjust the amount as necessary. Changes in our warranty liability during the period are as follows (in thousands):

	March 31,
	2014			2013
Balance as of the beginning of period	$	5,662		$	4,942
Warranties issued during the period	643			478
Settlements made during the period	(1,195		)	(1,341		)

The mortgage accrues interest at an annual rate of 7.91%, and the final payment is due on January 1, 2020. We estimate the fair value of the mortgage as of March 31, 2014 and December 31, 2013 was approximately $2.2 million and $2.3 million, respectively.
