Before BUTTLER, P.J., and WARREN and ROSSMAN, JJ.
BUTTLER, Presiding Judge.
Plaintiffs are three of 18 limited partners in Mt. Hood Meadows, Oreg., Ltd., a limited partnership established to carry on the business of constructing and operating a winter sports development in the Hood River Meadows area of the Mt. Hood National Forest. They brought this action against the general partner, Mt. Hood Meadows Development Corp., and the partnership for money had and received and conversion. The conversion claim was dismissed on the pleadings; after a trial on the merits, the *927 court awarded judgment to plaintiffs on their claim for money had and received. Defendants appeal, assigning as error the trial court's denial of their motion for judgment on the pleadings on the money had and received claim. ORCP 21B. We reverse.
The question is whether plaintiffs, as limited partners, have a right to compel the general partner to distribute to them all of the profits allocated to them under the provisions of the partnership agreement. For the years in which profits were earned after 1974, the general partner's board of directors voted to distribute only 50 percent of the limited partners' taxable profits. The remaining profits were retained and reinvested in the business. The trial court held that the general partner had no authority to retain profits and ordered that it distribute annually to all limited partners cash equal to the profits allocated to them.
Article X of the limited partnership agreement provides:
"POWERS AND RESPONSIBILITIES, COMPENSATION
"Management and control of the partnership business shall be vested exclusively in the general partner, who, except as otherwise herein provided, shall have all the rights and powers and be subject to all the restrictions and liabilities of a general partner. The general partner shall have the power to borrow funds for the partnership's business and to pledge, mortgage, assign or otherwise hypothecate any or all properties of the partnership to secure such borrowings.
"None of the limited partners shall have any voice or take any part in the control or management of the business of the partnership nor shall any limited partner have any power or authority to act for or on behalf of the partnership in any respect whatever; provided that nothing herein contained shall in any way affect the rights of the limited partners to dissolve the partnership as provided in Article XI hereof."
That section directs that all management decisions of the partnership be the responsibility of the general partner and that the limited partners have no right to take part in the control of the business. That provision protects the limited partners from becoming liable as general partners. Former ORS 69.280.[1] Management of the business necessarily includes decisions regarding the management of profits, unless the parties have specified otherwise in the limited partnership agreement.
*928 Article VII[2] of the agreement defines the partners' interest in the capital of the partnership:
"The partners' interest in the capital of the partnership shall be in the proportions in which the agreed capital contributions of each, increased by his share of profits, gains, credits, and additional capital contributions and decreased by his share of losses, expenses, deductions and withdrawals bears to the aggregate capital contributions of all partners so increased or decreased, as the case may be."
Article VI of the agreement describes each limited partner's interest in the profits.
"Each limited partner shall be entitled to a portion of the remainder of the profits after payment to the general partner as specified above, which bears the same ratio to such remainder as such limited partner's capital contribution bears to the total capital contribution of the limited partners."
A partner's interest in the capital of the partnership is made up of the partner's capital contributions and, in part, his share of undistributed profits. That is what, in accounting terms, constitutes a partner's capital account. Although Article VI, the only section of the agreement that addresses the partners' right to profits, describes the percentage of profits to which each partner is "entitled," it does not address the distribution of profits; it merely provides the method of calculating and allocating profits. We conclude that the agreement contains no provision expressly directing the general partner to distribute profits to the limited partners.
Plaintiffs argue that the authority to retain profits is one that must be granted expressly to the general partner and that, in the absence of a grant, is presumed to have been withheld. That proposition is too broad. With certain exceptions and unless otherwise agreed, a broad grant of authority to manage a business, such as that applicable here, includes the authority to conduct all affairs reasonably necessary or incidental to the expressly authorized business. Beeson et al. v. Hegstad et al., 199 Or. 325, 330, 261 P.2d 381 (1953); see Restatement (Second) Agency 189, § 73 (1958). Decisions regarding the management, including the distribution, of profits fall within that broad authority.
Profit is an accounting concept; its allocation takes place in the partnership books, and it may bear little or no relationship to cash on hand. Each partner is taxed on his distributable share of the profits, regardless of whether cash is actually distributed or whether it is available for distribution. For that reason, the partnership agreement must specify how the profits are to be allocated. The availability of cash for distribution, however, depends strictly on management's operation of the business. The business' future cash needs are also determined by management. That is why the decision as to how much, if any, of a limited partner's share of the profits is to be distributed is a management decision. If a limited partner were to take part in that aspect of the control of the business, the partner would risk the loss of his limited liability. Former ORS 69.280.
Plaintiffs assert that the general partner's decision to retain profits effectively forces the limited partners to make additional capital contributions to the partnership against their will, contrary to Article *929 VII of the agreement. See n. 2, supra. We do not agree that that is the result. A capital contribution is cash or property contributed by a partner; a capital contribution is, by definition, infused into the business from the outside and is not generated by the business. Black's Law Dictionary 189 (5th ed. 1979). If the partnership agreement had required that all profits be distributed, then perhaps the retention of profits could be viewed as an involuntary capital contribution by the partners. When, however, partnership profits are not required to be distributed, undistributed profits do not constitute a "capital contribution" under Article VII of the agreement. That article distinguishes a "capital contribution" from an increase in a partner's interest in the capital of the partnership because of his share of the profits, among other things, all of which comprise a partner's interest in the capital of the partnership.
Plaintiffs' final assertion meriting discussion is that the accumulation of profits in their capital accounts increased their liability. Plaintiffs' liability was not increased beyond that provided in Article VIII of the limited partnership agreement, under which their liability is limited to their "interest in the capital of the partnership."[3] It is not limited to their "capital contribution." Although it is true that their interest in the capital of the partnership increased with the increase in undistributed profits, they agreed in Article VII that undistributed profits be a component of their interest in the capital of the partnership and agreed in Article VIII that their liability be limited to that amount.
A limited partner's position is analogous to that of a corporate shareholder, whose role is that of an investor with limited liability, former ORS 69.280(1), and with no voice in the operation of the enterprise. See Lichtyger v. Franchard Corp., 18 N.Y.2d 528, 277 N.Y.S.2d 377, 223 N.E.2d 869 (1966). With limited exceptions, which do not include control over the distribution of profits, a limited partner who takes part in the control of the business may be held liable as a general partner. Former ORS 69.280. A general partner's relationship to the limited partners is analogous to the relationship of a corporate board of directors to the corporate shareholders; the general partner functions as a fiduciary with a duty of good faith and fair dealing. Bassan v. Investment Exchange Corp., 83 Wash.2d 922, 524 P.2d 233 (1974); see Iwasaki v. Iwasaki Bros., Inc., 58 Or. App. 543, 547, 649 P.2d 598 (1982). Like the corporate director's fiduciary responsibility to the shareholders for the declaration of dividends, the general partner's duty to the limited partners in the distribution of profit is discharged by decisions made in good faith that reflect legitimate business concerns. See Iwasaki v. Iwasaki Bros., Inc., supra. There is no contention here that the general partner acted in bad faith in failing to distribute all of the profits. The limited partners' right to a share of the profits of the partnership under former ORS 69.240(2)[4] is unrestricted; however, in the absence of a provision to the contrary in the partnership agreement, the right to a distribution of that share is subject to the good faith judgment of the general partner. The agreement is not ambiguous and contains no provision that would give plaintiffs the right to demand payment for undistributed profits. Accordingly, the trial court erred in denying defendants' motion for judgment on the pleadings. Given that conclusion, we need *930 not address defendants' other assignments of error.
Reversed and remanded for entry of judgment for defendants.
