It is impossible, within the limits of a single chapter, to discuss each kind of company separately. The investment value of street-railway bonds will be here considered, and it is felt that the general principles advanced, with slight modifications of detail, will be found equally applicable to a judgment of other forms of public-service securities.
I. Safety of Principal and Interest. In order to determine the safety of a street-railway company's bonds, the company must be subjected to a threefold examination, physical, financial, and political.
An examination must be made into the extent and condition of the physical property in order to ascertain whether the bonded debt is secured by property having a real market value in excess of the face amount of bonds issued. The first point to be determined is the extent and valuation of the company's real estate. If the appraised value of the land upon which power-houses and car-barns have been erected is alone greater than the amount of bonds outstanding, the investigation need go no further, for the bonds, in such a case, would be practically a real-estate mortgage. In most instances, however, this is very far from being the case; and after careful appraisal of the real estate it is then necessary to make a careful valuation of the other physical property; namely, power-plants, depots, car-sheds, roadway, and equipment.
It is usually impossible for the average investor to make such an examination himself, nor is it likely that he would possess sufficient technical knowledge to render his investigation of much value. For an accurate estimate of the value of a street-railway's physical property, it is usually necessary to depend upon the expert opinion of a trained engineer. It is a matter of regret that the average street-railway report can not be relied upon to furnish an accurate valuation of the physical property; and it is accordingly customary for careful bond-dealers, when they contemplate taking an issue of street-railway bonds for distribution among their clients, to have the property examined by a competent engineer, whose report then determines for them the question of taking the issue.
Disregarding the figures which show the cost of property and equipment upon the company's books, the engineer proceeds to make a careful estimate of the replacement value of the property, including real estate. If the result of the examination shows that the property could not be duplicated for the amount of the bond issue, the company occupies an unusually strong position—altho even in such a case some part of the value of the bonds comes from the strength of the company as a going concern.
In most cases, however, it is probably found that the bond issue is in excess of the value of real estate and the replacement value of the physical property, the balance representing a capitalization of the franchise.
To determine the real value of the franchise or franchises is a difficult matter and involves the whole question of the company's relations with the community which it serves and with the local lawmaking bodies.
The first question which arises is whether the franchise is perpetual or for a definite time, and the second whether it is partial or exclusive. Franchises vary greatly in these respects. Sometimes a franchise, apparently partial, is practically exclusive, owing to the fact that all the available space in the streets is already occupied by the company's own tracks. If the franchises of a company are limited as to time, it is expedient, if not imperative, that the bonds should mature before the expiration of the franchises.
If the company whose bonds are under examination satisfactorily passes this physical test—if it possesses real estate of considerable value, if the replacement value of the property is as great or nearly as great as the amount of the bonds, and if the franchises, while perhaps not perpetual or exclusive, are yet of longer duration than the bonds and render successful competition unlikely—the next step may then be taken; that is to say, an examination of the company's financial condition and earning capacity may be made.
The amount of its gross earnings should be examined and the figures scrutinized for a number of years back to discover whether its earnings are increasing or decreasing. The position in which the company stands for obtaining new traffic must be noted, and some estimate must be made of the stability of its earning power. In this connection the relations of the company to the public are of great importance. It must be learned whether the company follows the policy of conciliating or ignoring public sentiment.
