The plaintiff, an employee of Crimmins & Peirce Co., a Massachusetts corporation hereinafter called *228the corporation, purchased of the defendants 160 shares of the capital stock of the corporation. It was agreed in writing by the plaintiff and defendants that on the plaintiff ceasing to be employed by the corporation he would transfer his shares to the defendants, who were to pay him therefor “in cash, the value of said shares of stock as it shall appear upon the books of said corporation at the end of the last preceding fiscal year.” On December 31, 1921, the plaintiff ceased to be employed by the corporation and forthwith transferred to the defendants his shares. The end of the last preceding fiscal year it was agreed was December 31, 1920. The defendants paid the plaintiff the sum of $64,044.80. The books of the corporation were closed as of the close of business on June 30 and December 31 of each year, when credit and debit balances of various ledger accounts were transferred to a profit and loss account. On December 31,1920, the books showed a balance to the credit of profit and loss of $3,002,875.32. The valuation of the plaintiff’s stock was arrived at by adding this $3,002,875.32 to the par value of the outstanding common stock and dividing the sum obtained by the number of shares of common stock already issued and outstanding.
In 1924 it was found that the corporation was entitled to a reduction in taxes paid the Federal government for the year 1918, because of an error in its tax return for the year 1918. The error came about in this way: it was the practice of the corporation to take the inventory of merchandise at the close of each year at cost or market value, whichever was lower, and to make an arbitrary deduction covering possible losses due to shrinkage in value. The inventory thus made up showed a value of merchandise on hand December 31, 1917, and Jaíiuary 1, 1918, of $9,063,843.82. In 1918 the corporation was informed by the internal revenue officials that this arbitrary deduction could not be allowed; consequently, the corporation entered on its books as an additional valuation of merchandise an item of $1,449,673.58 as of December 31,1917. The accountants who made up the tax return for the year ending December 31, 1918, started the computation of net income with the inven*229tory of merchandise at $9,063,843.82, ignoring the additional item óf $1,449,673.58 which appeared on the books. This resulted in an overstatement of taxable net income to the extent of $1,449,673.58. In 1924 the error in the return was discovered. The computation of the tax was then revised by starting with an inventory of $10,513,517.40, that being the total of the depreciated inventory of $9,063,843.82 plus the additional merchandise item of $1,449,673.58, which the accountant who prepared the return had ignored. Making the new computation of the tax for 1918 on this basis, the United States agent reported, in 1924, that there had been an overassessment for 1918 of $681,718.94, which amount, less $59,545.62, an additional tax assessed for the year 1919, with interest to May 7,1925, was received by the corporation on October 5, 1925, by government check for $825,008.37.
The contention of the plaintiff is that he has not been paid the value of his stock “as it shall appear upon the books of said corporation”; that he is entitled to recover an additional sum equal to the proportional share of his stock in the $681,718.94 and interest thereon paid by the government. In the Superior Court, the judge ruled that the plaintiff was entitled to have included, as an asset in determining the value of his shares, the overpayment of taxes for the year 1918, less the additional tax for 1919, and found for the plaintiff in the sum of $13,113.88.
The written contracts of the parties stipulated that when the plaintiff ceased to be employed by the corporation he would forthwith transfer bis shares of stock therein to the defendants, who were thereupon to pay the plaintiff in cash “the value of said shares of stock as it shall appear upon the books of said corporation at the end of the last preceding fiscal year.” The amount which the plaintiff was to be paid was the value of his stock as shown by the books of the corporation for the preceding fiscal year. This fiscal year was the year ending December 31, 1920. It is not questioned that the books of the corporation made up for that year showed a profit and loss account of $3,002,875.32; that this computation was accurate. There was no error or mistake in ascertaining the value of the plaintiff’s stock *230according to the corporation books as they were kept for the preceding fiscal year. If the value determined by the corporation books showing the condition of the corporation in the year 1920 is to govern, then the plaintiff has been paid in full for the value of his stock.
The plaintiff’s contention is that he is entitled to share in the payment made to the corporation in 1925, by the United States, for the excess taxes for 1918. The defendants believed that the tax return for that year was correct. The error in this return was not discovered until 1924, after the plaintiff had transferred his stock and had been paid therefor. It is not contended that there was any deceit or unfair dealing by the defendants, and there was no error in the books. The error was in the tax return for the year 1918 which was not a part of the books. Whatever right the corporation might have to recover this overpayment of taxes, it did not appear on the books, and it was not to be expected that it would appear, as the defendants themselves and the officers of the corporation were in ignorance that this right existed. The additional valuation of $1,449,673.58 did, however, appear on the books, but the tax accountant ignored it in making up the tax return.
■ The books were correctly kept. Even if all the books of the corporation could be examined in order to determine the value of the stock, there was nothing in the accounts for the years preceding the fiscal year 1920, to show that the value of the stock was greater than that placed upon it as shown by the books for that year. Whether the method of making an arbitrary deduction in the inventory was followed or the additional sum of $1,449,673.58 for valuation of merchandise, as ordered by the internal revenue officials, was entered on the books, it made no difference in ascertaining the value of the stock at the close of the fiscal year 1920. Whichever method was pursued, so far as the real value of the corporation assets was concerned, it was correctly accounted for and fairly determined.
If an account receivable, honestly supposed to be of no value, was carried on the books for the year 1918 as worthless, and in 1925 the account was collected, it would probably *231not be contended that the plaintiff would be entitled to share in this payment. An inventory in 1920 might show an asset to be of no value; in 1925 this asset might be valuable, but under the plaintiff’s contract he agreed to be governed by the books, the value of his stock to be determined by what they disclosed. He was not to be called on to pay for losses or recover profits because it was subsequently discovered that the inventory was too high or too low.
The rights of the parties are to be determined in deciding on the value of this stock by the books of the corporation; and “as it shall appear upon the books of said corporation at the end of the last preceding fiscal year.” The plaintiff is bound by this agreement. It was agreed that the statement of profit and loss was “a correct computation”; that the claim against the United States to recover taxes for the year 1918 was not carried as an asset on the books, nor was the sum of $59,545.62 additional taxes for the year 1919, which was assessed after December 31, 1920, carried as a liability at any time during the year 1920. In these circumstances we are unable to see how the plaintiff can rightfully contend under his contract that he has not been fully paid the value of his stock.
The books did show the correct amount of assets for the year 1918, and it could be discovered what was the accurate amount of taxes for 1918; but this fact does not give the plaintiff a right to recover. One familiar with the Federal tax law who examined the tax return in the year 1918 and compared it with the corporation books for 1917 might have discovered the overpayment of taxes. But no examination of the books alone would show the excess payment and no examination of the books showing the condition of the corporation in the fiscal year preceding the settlement would make known the overpayment in the year 1918. The possibility of a return of taxes was not looked upon as an asset. The parties decided upon a definite and fixed method of arriving at the value of the stock which was to settle the value according to a standard agreed on, without delay or uncertainty, and unaffected by future contingencies. This method was the value of the stock as it appeared on the books at a certain *232time, that is, at the end of the last preceding fiscal year. It was not intended that the profits or losses were to remain in doubt; they were fixed by the statement honestly entered in the books.
The plaintiff relies on Early v. Moor, 249 Mass. 223, 225. That was a suit in equity between the executrix of one who, with the plaintiff, equally owned or controlled the stock of a corporation. Their agreement provided that the survivor was to purchase the stock of the deceased and to pay the fair book value, “the same to be ascertained by the regular and usual methods employed in the business of said corporation to ascertain the net worth of said corporation.” In the course of the opinion it was said at page 227: “The words 'fair book value’ are clear when construed in connection with the entire agreement. That value is 'to be ascertained by the regular and usual methods employed in the business of said corporation to ascertain the net worth of said corporation and the fair value of its said stock ’ . . . the value of the capital stock was not to be determined from the cost of the merchandise as charged on the books, nor by the full amount of the accounts receivable charged regardless of their actual value.” In the case at bar the books were to control, and there was no provision in the contract that the value of the shares was to be ascertained from any other sources except the books. It was the value appearing on the books for the preceding fiscal year without resort to other methods which was to “control; and it was the value as there shown upon which the parties acted in making the settlement. As the contract which must govern the rights of the parties shows the intention to take the books as they were, without going into other evidence in arriving at the value of the stock, the plaintiff could not be called on to aid in the payment of additional taxes for the time preceding his transfer of stock nor to participate in the repayment of taxes for such time.
It follows that the defendants’ exceptions are sustained, and judgment is to be entered for the defendants.
So ordered.
