The setting for this paper is 1955, an early date in terms of the pooling concept. Since ARB 48 was not issued until 1957, the conditions that surround the data selected for this paper must rest on ARB 40 for the most part. ARB 40 was issued in 1950. I recall the period well because I became interested in the problem about that time. The state of the art of pooling was, in my judgment, limited to a few sophisticates in reasonably large companies. As a matter of fact, many in academic circles did not have an appreciation of the pooling concept in 1955, nor did industry, in general, either. This is an important matter in trying to assess the significance of this paper. If, as I contend, widespread knowledge of the pooling concept was not the case, then the number of applications of the approach in mergers does not rest on a choice between purchase and pooling but rather purchase alone. Another matter which deserves attention is the pressure of taxation. The allowance of a tax-free reorganization placed a burden on accountants to adopt a method to handle the increasing traffic in this area. The substance of the problem was simply that assets in a tax-free reorganization would, if acquired, carry forward their book values to the acquirer. Because whole businesses were being transferred rather than discrete assets, the decision to use a procedure that conformed to the tax seems to have been made. The pooling concept was born to accommodate this problem. Some argue that financial accounting need not, in fact should not, conform to tax methods. Other accountants do not feel so rigid and are willing to adapt financial accounting to tax accounting, at least in important matters. Few would argue that a business combination is unimportant, because assets, personnel, and business status are all a part
