IBM's Acquisition of Lotus Development Corp.1 On July 5, 1995, International Business Machines (IBM) announced its acquisition of Lotus Development Corporation for a price of $3.2 billion ($2.9 billion in net cash). Lotus was a Cambridge, MA-based company that developed, marketed and supported software products and services for individuals and organizations. It had gained success with the release of its first product, Lotus 1-2-3, a financial spreadsheet program. Also successful were such subsequent products as Open Messaging Interface (a program that allowed users to send mail without leaving the program in which they were currently working) and Notes (a "groupware" product designed to allow groups of remote users to collaborate simultaneously). At the time it was acquired by IBM, Lotus had numerous software technologies in various stages of production and development. Current software products included those being produced and marketed as of the acquisition date as well as products in development that had reached technological feasibility. In-process research and development (R&D) included products in development that had not attained technological feasibility as well as future follow-on products which did not exist at the acquisition date, but were conceptual in nature and were expected to evolve into future product lines. As shown in Exhibit 1, Lotus had less than $1 billion of identifiable tangible and intangible net assets in 1995. Since IBM's acquisition was accounted for as a purchase, the difference between the acquisition price and the market value of net assets gave rise to goodwill. However, IBM recognized substantially less goodwill than one might have expected: it assigned $1.84 billion of the acquisition price to the value of in-process R&D. Then, in accordance with generally accepted (but somewhat controversial) accounting practices, IBM wrote off (expensed) this value immediately. Why is this practice controversial? Exhibit 2 explains the rationale and requirements for writing off in-process R&D. Exhibit 3 provides contrasting views on following this practice. Exhibit 4 illustrates the methodology IBM used to value current products and in-process R&D acquired from Lotus (the methodology is further described in Exhibit 2). IBM's financial statements and notes for 1995 appear in Exhibit 5. 1 This case has been adapted from "Valuation of and Accounting for Purchased Research and Development Technology: IBM's Acquisition of Lotus" by Prof. Jennifer Francis (Duke University). The source case was prepared as the basis for class discussion and not to illustrate either effective or ineffective handling of an administrative situation. 1 Exhibit 1 (Excerpt from IBM 10-K report for 1995) Lotus Development Corporation On July 5, 1995, the company acquired all outstanding shares of Lotus for approximately $3.2 billion ($2.9 billion in net cash). The company engaged a nationally recognized, independent appraisal firm to express an opinion on the fair market value of the assets acquired to serve as a basis for allocation of the purchase price to the various classes of assets. The appraisal included both tangible and identifiable intangible assets, as well as software technology. The company allocated the total purchase price as follows: (DOLLARS IN MILLIONS) Tangible net assets Identifiable intangible assets Current software products Purchased in-process research and development Goodwill Deferred tax liabilities related to identifiable intangible assets Total $ 325 542 290 1,840 540 (291) -------$ 3,246 The tangible net assets consisted primarily of cash, accounts receivable, land, buildings, leasehold improvements and other personal property. The identifiable intangible assets consisted of trademarks ($369 million) and other items (including employee agreements and leasehold interests) totaling $173 million. The identifiable intangible assets and goodwill will be amortized on a straight-line basis over a five-year period. The software technology valuation was accomplished through the application of an income approach. Projected debt-free income (revenue net of provision for operating expenses, income taxes and returns on requisite assets) were discounted to a present value. This approach was used for each of the Lotus product lines. Software technology was divided into two categories: current software products and in-process research and development. The fair market value of the purchased current software products was determined to be $290 million. This amount was recorded as an asset and is being amortized on a straight-line basis over two years. Purchased in-process research and development included the value of software products still in the development stage and not considered to have reached the technological feasibility stage. As a result of the valuation, the fair market value of the purchased in-process research and development was determined to be $1,840 million. In accordance with applicable accounting rules, this amount was expensed upon acquisition in the third quarter of 1995. 2 Exhibit 2 Accounting for Research and Development FAS No. 2, “Accounting for Research and Development Costs,” requires that all R&D costs be expensed in the period when they are incurred. This accounting treatment focuses on the degree of uncertainty associated with the future benefits of individual R&D projects. This uncertainty causes R&D expenses to fail the measurability test: it is not possible to recognize as an asset a resource whose future economic benefits are neither identifiable nor objectively measurable. FAS No. 86, “Accounting for the Costs of Computer Software…” provides a partial exception to the rule of expensing all R&D costs as incurred. It permits the capitalization of costs incurred subsequent to technological feasibility, but continues to require expensing of costs that precede technological feasibility. FASB Interpretation No. 4 (FIN-4) provides additional guidance on R&D when accounting for acquisitions. It specifies that costs of purchasing another firm should be assigned to all identifiable tangible and intangible assets, including any that result from R&D activities of the acquired firm or are to be used in the R&D activities of the combined enterprise. FIN-4 further states that costs of acquired R&D should be charged to expense unless the test of alternative future use is met. The disclosure in Exhibit 1 reveals that IBM used the Discounted Future Benefit approach to valuing the in-process R&D acquired from Lotus. The method involves estimating the future monetary benefits associated with an asset, and discounting those benefits to a present value using a discount rate that reflects the riskiness of the stream of benefits. This approach is typically used to value income producing real estate and many intangible assets. In these situations, future benefits are often measured in terms of net-of-tax earnings, after allowing for a pre-determined return on the assets employed. As illustrated in Exhibit 4,2 IBM computed for each acquired Lotus product the discounted value of the projected future stream of revenue net of operating expenses, income taxes, and returns on related assets. The company used a forecast horizon of ten years, with a terminal calculation for the perpetuity value of the after-tax earnings of future follow-up products. Factors used to estimate product life expectancy included the historical experience of prior versions of the software, plans with respect to releasing future versions of the software, and industry norms. Lotus’ historical and projected experience of issuing new product versions indicated that the typical product had an average life of two (2) to five (5) years. 2 All data in Exhibit 4 and the product descriptions associated with them are illustrative only. They neither reflect actual technologies acquired by IBM from Lotus, nor represent actual data used. However, for the purposes of this case, you should treat them as “real data” that are used internally and not publicly disclosed. Exhibit 4 shows the valuation of WordSpeak, a technology to convert oral communications into editable (typed) documents. This technology was in the preliminary development state when IBM acquired Lotus, and was not expected to be marketable until the year 2000. Introduction of WordSpeak was expected to revolutionize word processing technology. 3 Exhibit 3 Comments on Writing-Off Acquired R&D In the Sept. 97 Mergers & Acquisitions, Bryan Browning of Valuation Research Corp. wrote: [I]t appears that some acquirers have been going to great lengths to maximize the cost allocated to R&D and to minimize that ascribed to goodwill. The FASB and the SEC are concerned because excessive R&D write-offs would result in low book values for companies' assets and in overstated returns on equity. ... So, for companies planning an acquisition in the near future, beware: A large allocation to R&D will have to be supported by an expert, well-documented valuation. In May, 1997, Elizabeth MacDonald of the Wall Street Journal wrote: Jack Ciesielski, editor of the Analyst's Accounting Observer, a Baltimore publication for stock analysts, warns, "Investors should be careful of subsequent earnings posted by acquirers using this rule, because they are a bit jazzed." Gabrielle Napolitano, a securities analyst who follows accounting issues at Goldman Sachs, holds a similar opinion: "Acquiring companies may be assigning too high a value to this in-process R&D, distorting subsequent earnings." … Ciesielski says the sheer size of some of the R&D write-downs indicates that some acquiring companies are abusing the rules by including too much goodwill. But most companies don't release the details of the calculations they use to arrive at the write-down amounts. … Corporate Growth Report (Weekly) in July, 1995 quoted other “experts” as saying: "It's like manna from heaven for a company's stock." (Robert Willens, accounting analyst at Lehman Brothers). This is the reason [FIN-4] has been a boon for high-tech acquirers this year. IBM is a prime example. At least $ 900 million of the $ 2.6 million in goodwill BM is generating in buying Lotus will be assigned by IBM to R&D, and thus instantly deducted from profits instead of being amortized for years. "Investors always like to get such big charges out of the way as soon as possible," says Douglas Robinson, a senior vice president of Computer Associates. In prior years ('93 & '94), Novell expensed a whopping 80% of its purchase price for Unix System Laboratories and 75% of its payment for the Quattro Pro software line.

Investments in business entities in which IBM does not have control, but has the ability to exercise significant influence over operating and financial policies (generally 20 - 50 percent ownership), are accounted for by the equity method. Other investments are accounted for by the cost method. Revenue Revenue from hardware sales or sales-type leases is recognized when the product is shipped. Revenue from one-time-charge licensed software is recognized when the program is shipped with an appropriate deferral for postcontract customer support. This deferral is earned over the support period. Revenue from monthly software licenses is recognized as license fees accrue; from maintenance and services over the contractual period or as the services are performed; from rentals and operating leases, monthly as the fees accrue; and from financing at level rates of return over the term of the lease or receivable. Revenue is reduced for estimated customer returns and allowances. Selling Expenses Selling expenses are charged against income as incurred. Income Taxes Income tax expense is based on reported earnings before income taxes. Deferred income taxes reflect the impact of temporary differences between assets and liabilities recognized for financial reporting purposes and such amounts recognized for tax purposes. In accordance with Statement of Financial Accounting Standards (SFAS) 109, "Accounting for Income Taxes," these deferred taxes are measured by applying currently enacted tax laws. Cash Equivalents All highly liquid investments with a maturity of three months or less at date of purchase are carried at fair value and considered to be cash equivalents. Inventories Raw materials, work in process, and finished goods are stated at the lower of average cost or market. Depreciation Plant, rental machines and other property are carried at cost, and depreciated over their estimated useful lives using the straight-line method. 8 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS International Business Machines Corporation and Subsidiary Companies Software Costs related to the conceptual formulation and design of licensed programs are expensed as research and development. Costs incurred subsequent to establishment of technological feasibility to produce the finished product are capitalized. The annual amortization of the capitalized amounts is the greater of the amount computed based on the estimated revenue distribution over the products' revenue-producing lives, or the straight-line method, and is applied over periods ranging up to four years. Periodic reviews are performed to ensure that unamortized program costs remain recoverable from future revenues. Costs to support or service licensed programs are charged against income as incurred, or when related revenue is recognized, whichever occurs first. Retirement Plans and Nonpension Postretirement Benefits Current service costs of retirement plans and postretirement healthcare and life insurance benefits are accrued for in the period. Prior service costs resulting from amendments to the plans are amortized over the average remaining service period of employees expected to receive benefits. Goodwill Goodwill is charged to earnings on a straight-line basis over the periods estimated to be benefited, currently not exceeding five years. Common Stock Common stock refers to the $1.25 par value capital stock, as designated in the company's Certificate of Incorporation. Earnings (loss) per common share amounts are computed by dividing earnings (loss) after deduction of preferred stock dividends and transaction costs by the average number of common shares outstanding in the period. B ACCOUNTING CHANGES The company implemented new accounting standards in 1995, 1994 and 1993. None of these standards had a material effect on the financial position or results of operations of the company. Management uses estimates in preparing the consolidated financial statements, in conformity with generally accepted accounting principles. Significant estimates include collectibility of accounts receivable, warranty costs, profitability on long-term contracts, as well as recoverability of capitalized software costs, long-term fixed assets and residual values. The company regularly assesses these estimates and, while actual results may differ from these estimates, management believes that material changes will not occur in the near term.

The net change in the total valuation allowance for the year ended December 31, 1995, was a decrease of $683 million, of which approximately $600 million was due to the realization of previously unrecognized benefits in the current year. It is reasonably possible that the deferred tax asset valuation allowance could decrease significantly in the near term, depending on the company's ability to generate sufficient taxable income in multiple tax jurisdictions. 12 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS International Business Machines Corporation and Subsidiary Companies The consolidated effective income tax rate was 47 percent in 1995, 41 percent in 1994 and (9) percent in 1993.
