EAGLES, Chief Judge.
The North Carolina Rate Bureau (“Bureau”) appeals from an order entered by the North Carolina Commissioner of Insurance (“Commissioner”) that denied the Bureau’s request for an adjustment in automobile insurance rates. The Bureau asserts four arguments on appeal: (1) the Commissioner improperly considered investment income on capital and surplus funds while deriving his underwriting profit provisions; (2) the Commissioner did not give due consideration to dividends and deviations; (3) the Commissioner overstated the amount of investment income generated from policyholder-supplied funds; and (4) the Commissioner improperly substituted his own ratemaking procedure. After careful review of the record, briefs and arguments of counsel, we discern no error and affirm the Commissioner’s order.
The Bureau is a statutorily created entity. The Bureau was created by the General Assembly to replace and assume the duties of the North Carolina Automobile Rate Administrative Office, the North Carolina Fire Insurance Rating Bureau, and the Compensation Rating and Inspection Bureau of North Carolina. G.S. § 58-36-1(1) (2001). The Bureau is not an agency of the State. See Allstate Ins. Co. v. Lanier, 242 F. Supp. 73 (E.D.N.C. 1965), aff'd, 361 F.2d 870 (4th Cir.), cert. denied, 385 U.S. 930, 17 L. Ed. 2d 212 (1966). It represents the companies that sell automobile insurance in North Carolina, along with other types of insurers. See G.S. § 58-36-1(1).
The Commissioner of Insurance is an elected official of the State of North Carolina. G.S. § 58-2-5 (2001). The Commissioner’s duties as chief officer of the Department of Insurance are broadly described as “the execution of laws relating to insurance.” G.S. § 58-2-1 (2001). The North Carolina Supreme Court has listed the Commissioner’s duties as follows:
[F]aithfully executing all laws governing insurance companies and the authority to adopt rules to enforce that law; preventing practices injurious to the public; furnishing the necessary forms for statements required by companies, associations, orders, or bureaus; reporting to the Attorney General any violations of law relating to insurance companies; instituting civil actions or criminal prosecutions for violations of the insurance statutes; giving a statement or synopsis of any insurance contract upon proper application by any citizen; administering all oaths required in the discharge of his official duty; compiling and making available to *419the public the lists of rates charged, including explanations of coverages provided by insurers; and adopting rules governing what constitutes an uninsurable facility.
State ex rel. Comm’r of Ins. v. N.C. Rate Bureau, 350 N.C. 539, 541, 516 S.E.2d 150, 151 (“1996 Auto”) (citing G.S. § 58-2-40), reh’g denied, 350 N.C. 852, 539 S.E.2d 11 (1999).
An insurance company may write insurance in North Carolina only after it has become a member of the Bureau. G.S. § 58-36-5 (2001). The Bureau files a rate change proposal with the Commissioner on behalf of its member companies. G.S. § 58-36-1(3) (2001). Any rate change must be approved by the Commissioner. G.S. § 58-36-70(a) (2001). If the Commissioner does not approve the Bureau’s proposed rates, the Commissioner may set the insurance rates according to statute. G.S. § 58-36-70(d) (2001); see G.S. § 58-36-10 (2001).
After the Commissioner enters an order that rejects the Bureau’s ratemaking structure, the Bureau may appeal to this Court. G.S. §§ 58-2-80, 58-36-25 (2001). The two most recent filings by the Bureau have resulted in appeals to this Court and the Supreme Court. The disagreement between the Bureau and the Commissioner regarding the legal significance of the two previous appeals forms the basis for the current appeal.
The Bureau filed a rate adjustment request for automobile insurance on 1 February 1994. The Commissioner entered an order on 28 September 1994 rejecting .the Bureau’s rates and substituting a different schedule of rates. The Bureau appealed to this Court. In an opinion dated 17 December 1996, this Court remanded the case to the Commissioner with instructions to modify his order. The Commissioner issued a new, modified order on 10 September 1997. The 10 September 1997 order was reversed on appeal to this Court on 29 December 1998.
While the 1994 filing proceeded on appeal, the Bureau filed for another rate change on 1 May 1995. The Bureau amended its filing on 1 April 1996. After hearings in July and August 1996, the Commissioner disapproved the Bureau’s rate proposal. By orders issued on 4 October 1996 and 31 October 1996 the Commissioner lowered rates for car insurance by 8.3% and raised the motorcycle insurance rates by 3.2%. In an opinion filed on 16 June 1998, this Court reversed the Commissioner’s orders in part and affirmed in part. The *420Supreme Court affirmed the Court of Appeals’ opinion on 25 June 1999. Both the 1994 and 1996 rate filing disputes were eventually settled by the parties.
The Bureau filed the requested rate change at issue here on 1 May 2001. The filing requested an increase of 10.6% for private passenger automobile rates and a decrease of 2.4% for motorcycle rates. The Commissioner held a hearing on the matter from 25 September 2001 until 31 October 2001. The Bureau’s filing was over 1,000 pages in length. The evidence included nearly seventy exhibits, testimony from nine expert witnesses and four additional witnesses. The Commissioner rejected the Bureau’s requested rates in his order dated 14 December 2001. Instead, the Commissioner ordered a rate reduction of 13.0% for automobile rates and a reduction of 15.9% for motorcycles. The Bureau appeals from this order.
When reviewing an order by the Commission, this Court “must examine the whole record and determine whether the Commissioner’s conclusions of law are supported by material and substantial evidence.” State ex rel. Comm’r of Ins. v. N.C. Rate Bureau, 129 N.C. App. 662, 664, 501 S.E.2d 681, 684 (1998) (“1996 Auto-COA”), aff’d, 350 N.C. 539, 516 S.E.2d 150 (1999). "The whole record test requires the reviewing court to consider the record evidence supporting the Commissioner’s order, to also consider the record evidence contradicting the Commissioner’s findings, and to determine if the Commissioner’s decision had a rational basis in the material and substantial evidence offered.” State ex rel. Comr. of Ins. v. Rate Bureau, 124 N.C. App. 674, 678, 478 S.E.2d 794, 797 (1996) (“1994 Auto”) (quoting State ex rel. Comr. of Insurance v. N.C. Rate Bureau, 75 N.C. App. 201, 208, 331 S.E.2d 124, 131, disc. rev. denied, 314 N.C. 547, 335 S.E.2d 319 (1985) (“1983 Farm”)), disc. rev. denied, 346 N.C. App. 184, 486 S.E.2d 217 (1997). “Substantial evidence is ‘such relevant evidence as a reasonable mind might accept as adequate to support a conclusion.’ It is ‘more than a scintilla or a permissible inference.’ ” 1994 Auto, 124 N.C. App. at 678, 478 S.E.2d at 797 (citations omitted) (quoting Comr. of Insurance v. Automobile Rate Office, 287 N.C. 192, 205, 214 S.E.2d 98, 106 (1975)).
The Commissioner determines the weight and sufficiency of the evidence presented during the hearing, including the credibility of any witnesses. See State ex rel. Comr. of Insurance v. N. C. Rate Bureau, 96 N.C. App. 220, 221, 385 S.E.2d 510, 511 (1989) ("1987 Workers’ Compensation”). “[I]t is not our function to substitute our judgment for that of the Commissioner when the evidence is con*421flicting.” 1987 Workers’ Compensation, 96 N.C. App. at 221, 385 S.E.2d at 511. Instead, the Commissioner’s order is presumed correct if it is supported by substantial evidence. G.S. §§ 58-2-80 and 58-2-90(e) (2001). The order must conform to the guidelines set out in G.S. § 58-36-10:
(1) Rates or loss costs shall not be excessive, inadequate or unfairly discriminatory.
(2) Due consideration shall be given to actual loss and expense experience within this State for the most recent three-year period for which that information is available; to prospective loss and expense experience within this State; to the hazards of conflagration and catastrophe; to a reasonable margin for underwriting profit and to contingencies; to dividends, savings, or unabsorbed premium deposits allowed or returned by insurers to their policyholders, members, or subscribers; to investment income earned or realized by insurers from their unearned premium, loss, and loss expense reserve funds generated from business within this State; and to all other relevant factors within this State: Provided, however, that countrywide expense and loss experience and other countrywide data may be considered only where credible North Carolina experience or data is not available.
G.S. § 58-36-10. As long as the Commissioner’s order meets the criteria of G.S. § 58-36-10 and is supported by material and substantial evidence, the order should be upheld.
I.
The Bureau first argues that the Commissioner improperly considered investment income from capital and surplus funds while calculating the ordered insurance rates. In order to analyze the Bureau’s argument, we must first look at the structure of the insurance industry and the holdings of the 1994 Auto and 1996 Auto cases. See 1996 Auto, 350 N.C. 539, 516 S.E.2d 150 (1999); 1994 Auto, 124 N.C. App. 674, 478 S.E.2d 794 (1996).
An insurance company’s total profit is derived from two distinct parts of the insurance business — (1) profit earned by the insurance operations and (2) profits earned by investing capital and surplus funds. The profit from insurance operations includes both the underwriting profit and investment income from policyholder-supplied funds. The underwriting profit can be defined as the difference *422between insurance premiums collected and the amount the company pays out for losses and expenses. Policyholder-supplied funds are the amount of premiums paid to the insurance company. Policyholder-supplied funds are usually invested during the insurance coverage period.
The investment income produced by policyholder-supplied funds should be given due consideration during the ratemaking process. See G.S. § 58-36-10(2). The underwriting profit portion has been the traditional focus of the dispute between the Commissioner and the Bureau. In past orders, the Commissioner improperly considered investment income from capital and surplus funds. See 1996 Auto, 350 N.C. 539, 516 S.E.2d 150 (1999); 1994 Auto, 124 N.C. App. 674, 478 S.E.2d 794 (1996).
In addition to the statutory structure, this Court and the Supreme Court have placed additional requirements upon the ratemaking process:
Three basic principles of law pertain to the setting of insurance rates: (1) the Commissioner must set rates that will produce a fair and reasonable profit and no more; (2) what constitutes a fair and reasonable profit ‘involves consideration of profits accepted by the investment market as reasonable in business ventures of comparable risk’; and (3) the underwriting business, which includes the collection and investment of premiums, is the only basis for calculating the profit provisions.
1996 Auto, 350 N.C. at 541, 516 S.E.2d at 151 (citations omitted) (quoting In re N.C. Fire Ins. Rating Bureau, 275 N.C. 15, 39, 165 S.E.2d 207, 224 (1965)). In the orders that gave rise to the 1994 Auto and 1996 Auto appeals, the Commissioner defined “business ventures of comparable risk” as the total profit of the insurance industry. In order to set a rate equal to comparable businesses in those orders, the Commissioner subtracted capital investment income and investment income from policyholder-supplied funds from total returns to reach the underwriting profit:
Total profits of the industry
- capital/surplus investment income
= profits from insurance operations.
*423Profits from insurance operations
- income from policyholder-supplied funds
= underwriting profit.
Both orders (1994 and 1996) were reversed because the Commissioner improperly considered the investment income on capital and surplus funds. See 1996 Auto, 350 N.C. at 545, 516 S.E. 2d at 153-54 (“This Court has made it clear that unless the legislature changes the law, investment income from capital and surplus cannot be considered when setting insurance rates.”) and 1994 Auto, 124 N.C. App. at 686, 478 S.E.2d at 802 (“The formula used must exclude investment income earned on capital and surplus.”). The Supreme Court prohibited the Commissioner from including capital and surplus income in the ratemaking formula because “[i]n determining whether an insurer has made a reasonable profit, the amount of business done rather than its capital should be considered . . . .” Comr. of Insurance v. Rate Bureau, 300 N.C. 381, 444, 269 S.E.2d 547, 586 (1980) (“1977 Auto”) (quoting 2 Ronald A. Anderson, Couch Cyclopedia of Insurance Law § 21:38 (2d ed. 1959)). Here, the Bureau argues that the Commissioner has committed the same error in his 2001 order as he did in the 1994 and 1996 orders. We disagree.
In the 2001 order, the Commissioner altered his ratemaking formula in one significant way. Rather than attempting to find a total return, the Commissioner set the return on insurance operations as his target. The Commissioner made the following pertinent findings of fact:
150. The Bureau proposes a return on operations equivalent to a target total return. A target total return is an appropriate return for the whole of an insurance company taking into account investment income from capital and surplus.
151. The Bureau’s target total return is a range of 13.1% to 15.3% and is based upon the cost of capital with the addition of a .49% market to book conversion factor. [Expert witness] Appel indicates that the law in North Carolina allows for a return on operations in this range.
152. The Bureau uses a cost of capital as a measure of the returns that other businesses of comparable risk can earn in the market. However, the returns that the cost of capital measures are the returns those other businesses earn from all sources of *424income. Thus, the cost of capital is a total return, which in the insurance industry includes consideration of income from capital and surplus.
153. Department witnesses Cohn, Schwartz and D’Arcy testify that the Bureau’s total return includes investment income on capital and surplus by virtue of the cost of capital calculation, described more fully below.
156. In other jurisdictions, setting the cost of capital as the target return is appropriate; however, other jurisdictions may consider all sources of income in calculating profit. In North Carolina, only one source of income, the insurance operations, may be considered, while the investment income from capital and surplus may not.
159. Miller indicates that the law in North Carolina is unique in that insurers are allowed a return on operations which, in other States, would be equivalent to the return on operations plus the return on capital and surplus. Miller’s statement, thus, substantiates the Department’s claims that the Bureau’s return includes consideration of investment income on capital and surplus.
161. In addition to the Bureau’s consideration of investment income from capital and surplus in setting the target return, the Bureau’s target return is excessive. In calculating the total return as the target, the Bureau is setting the return for the insurance operations alone (which is a partial return) commensurate with the total returns of other businesses, including the insurance business. This is simply not “comparable” as required by law.
162. The lack of “comparability” is evidenced by the Bureau’s prospective range of returns of 13.1% to 15.3% compared to the average pre-tax historical returns on insurance operations during an eighteen year period of the countrywide property/ casualty industry of approximately 3.7% and the ten year average pre-tax returns in competitive rating states of 4.3% liability and 6.4% physical damage. This lack of “comparability” is further evidenced by the resulting profit provisions of 9.5% and 14.0%, *425which are higher than several of the witnesses have ever encountered in any jurisdiction and certainly higher than the profit provisions recently utilized by the top ten writers in three neighboring states.
163. In contrast to the Bureau, the Department witnesses calculate a return on operations taking into consideration only the income generated by the insurance activity.
164. The Department witnesses’ recommended returns are compared to the risk or operational returns (partial returns) of businesses of comparable risk.
165. The returns which the Department witnesses propose range from pre-tax returns of 4.3% to 4.5% for liability and 3.5% to 6.4% for physical damage to post tax returns of 3.7% to 6.8% for liability and 4.3% to 6.8% for physical damage.
166. The Department witnesses recommend a return on operations that is not a total return because North Carolina law requires that profit be set on the insurance operations only and that profit from the investment business not be considered. Furthermore, a return on operations that is not a total return provides the proper comparison to businesses of comparable risk.
167. Unlike the Bureau, the Department witnesses did not recommend a target total return because: (1) a total return includes consideration of investment income from capital and surplus; (2) calculating a return for only one source of insurance industry income based upon the returns generated by all sources of income of other businesses does not constitute “comparable risk,” as required by the law of this State.
168. The evidence in this case is overwhelming that it is impossible to calculate a target total return without considering investment income on capital and surplus.
169. In an attempt to circumvent the illegality of including investment income from capital and surplus in the calculation of the target rate of return, Bureau witness Appel states that the prohibition against considering investment income from capital and surplus applies only to the calculation of the profit provisions, not to the establishment of a target rate of return. However, there is absolutely no legal foundation for this con*426tention and the recent North Carolina Supreme Court decision in the 1996 case states otherwise.
170. Based upon the material and substantial evidence in this case, the Commissioner finds that the appropriate target rate of return in this case is a return on operations which is not equivalent to a total return. A total return requires consideration of investment income from capital and surplus which violates the ratemaking laws of this State. Furthermore, a total return makes an inappropriate comparison to businesses that are not of comparable risk, which leads to excessive returns. For those reasons, the Bureau’s target range of returns is herein rejected.
(Internal citations omitted.) In this order, the Commissioner focused on the return on insurance operations as the appropriate target for his calculations. In order to compare the insurance operations return to an industry of comparable risk, the Commissioner relied upon an expert opinion by Department witness Allan I. Schwartz. Schwartz testified that the eighteen year average return on insurance operations for the property and casualty insurance industry was 3.7%. Schwartz adjusted his estimate of the return on operations in order to account for the slight difference in risk between the property and casualty industry and the private passenger automobile insurance industry. The Bureau has not argued that this property and casualty industry information is not indicative of an industry of comparable risk. Indeed, we note that the Bureau’s own expert, Dr. James H. Vander Weide, used property and casualty industry information when formulating his expert opinion. G.S. § 58-36-10(2) does not require the Commissioner or any expert witness to use only three years of North Carolina data when calculating the reasonable margin of underwriting profit. Those geographical and temporal restrictions only apply to the consideration of the loss and expense experience, which is not in dispute here. As a result, we hold that the evidence regarding the eighteen year average return on insurance operations is “more than a scintilla or a permissible inference” that sufficiently supports the Commissioner’s setting of rates.
In addition, we find the Bureau’s argument that the Commissioner must set his target as the total rate of return to be unpersuasive. No statute or any case has required the Commissioner to focus on the total rate of return for the insurance industry. Instead, previous appellate court opinions have declared that the return on operations is the only portion of income the Commissioner can consider during the ratemaking process. If the Commissioner had compared *427total returns here, as he did in previous ratemaking orders, the Commissioner would have been required to add capital and surplus funds somehow. By using insurance operations as the comparable industry, the Commissioner did not need to consider investment income on capital and surplus funds. Accordingly, the investment income bn capital and surplus funds has not been used in the 2001 ratemaking calculation. The Commissioner’s underwriting profit provision comports with the requirements of G.S. § 58-36-10 as well as the holdings of 1994 Auto and 1996 Auto. We conclude there is substantial evidence to support the Commissioner’s findings of fact and conclusions of law on this issue. Therefore this assignment of error is denied.
II.
The Bureau next argues that the Commissioner failed to give due consideration to the impact of policyholder dividends and rate deviations in his ratemaking calculations. We disagree.
Policyholder dividends are a return of premiums to insurance purchasers, much like a rebate. Policyholders pay premiums at the manual rate, then receive a rebate or “dividend” at the end of the policy term. See G.S. § 58-36-60 (2001). The manual rate is set by the Commissioner through the ratemaking process and is the rate insurance companies must charge customers unless a deviation is allowed. Rate deviations occur when a company receives permission to charge certain policyholders more or less than the manual rate. See G.S. § 58-36-30 (2001). If a policyholder is given a rate deviation, the policyholder pays less than the manual rate from the beginning of the policy period.
The Bureau contends that dividends and deviations are a necessary tool for competition among insurance companies. Without deviations or dividends, the Bureau argues that insurance companies could not attract “good risk” policyholders. According to its argument, dividends and deviations are not profits. The Bureau believes that an adjustment of 5.0% should be included as a separate term in the ratemaking calculation in order to counteract the effect of dividends and deviations. Without this provision, the Bureau argues that a premium shortfall will occur. This argument is unpersuasive.
Due consideration of policyholder dividends and rate deviations is required by statute. See G.S. § 58-36-10(2) (“Due consideration shall be given ... to dividends, savings or unabsorbed premium deposits *428allowed or returned by insurers to their policyholders, members, or subscribers.”). The 1994 Auto, 1996 Auto-COA, and 1996 Auto cases are also instructive on this issue because the treatment of dividends and deviations was considered in those appeals.
The ratemaking formula is not required to contain an explicit adjustment for dividends and deviations in order to prove due consideration was given to them. See 1996 Auto, 350 N.C. at 547, 516 S.E.2d at 154-55 (“ ‘[D]ue consideration’ does not require that a numerical adjustment of the rates be made in order to reflect the effects of dividends and deviations.”); 1996 Auto-COA, 129 N.C. App. at 667, 501 S.E.2d at 686; 1994 Auto, 124 N.C. App. at 681, 478 S.E.2d at 799. It has also been held that dividends and deviations can be treated as profits rather than as expenses. 1996 Auto-COA, 129 N.C. App. at 668, 501 S.E.2d at 686 (citing 1994 Auto, 124 N.C. App. at 682, 478 S.E.2d at 800). The Bureau’s arguments contradict these established guidelines and are therefore overruled.
The Commissioner made the following pertinent findings of fact regarding dividends and deviations:
406. The Commissioner finds and concludes that any margin for the payment of dividends and deviations in excess of the margin provided for in the average manual premium is unreasonable and produces rates that are excessive and unfairly discriminatory.
407. Based on the foregoing, the Commissioner finds that an average manual rate with profit provisions of -2.8% for liability and +1.0% for physical damage will provide approximately 4.5% to 5.0% of manual premiums, or approximately $120-135 million, as savings that may be used to pay dividends and to grant deviations to insureds, assuming the same book of business.
408. The approximately 4.5% to 5.0% of premium or approximately $120-135 million provided in the manual rate for policyholder dividends and deviations by the Bureau member companies is reasonable, adequate and is provided in the rates, which are adopted and approved herein by this Order and which are not inadequate, excessive, or unfairly discriminatory.
409. Dividends and deviations in excess of the approximately 4.5% to 5.0% of premium or approximately $120-135 million may occur, as in the past. If so, the excess may come from companies which are prepared to accept, on an individual basis, *429less than the average profit provided in the manual rate, from accumulated surplus, from lower expenses, from an excessive rate level implemented by the Bureau or from sources which are not within the jurisdiction of the Commissioner.
410. This approximately 4.5% to 5.0% of premium will become retained earnings, i.e., profit, if it is not distributed as dividends and deviations. Including more than the 4.5% to 5.0% of premium that comes from savings for dividends and deviations in the rate calculation will cause rates to spiral and become excessive and unfairly discriminatory.
The Commissioner also found that dividends and deviations are transfer payments or profit. The Commissioner found that including a specific provision for dividends and deviations was unnecessary because the use of an average rate implicitly included consideration of dividends and deviations. After careful review, we conclude that there is sufficient record evidence to support the Commissioner’s findings.
The Commissioner’s reasons for refusing to adjust the ratemak-ing formula by adding a provision for dividends and deviations are twofold. First he states that dividends and deviations should not be added to the rate because they are already included within the computation of the average rate. The average rate takes into account the companies that deviate as well as those that do not deviate.. Similarly, the average is already reduced by those companies that provide dividends. Any explicit provision would double-count dividends and deviations, which would lead to “spiraling” — a rise in insurance rates. In addition, the Commissioner finds that dividends and deviations are part of profit, instead of an expense for insurance companies. Since a provision for profit already exists, adding an additional provision in the ratemaking formula for these types of profit is redundant.
We hold that the Commissioner’s findings of fact are based upon substantial and competent evidence. The Commissioner’s findings of fact indicate that the insurance industry will have approximately 4.5% to 5.0% profit to use for dividends and deviations if they choose to do so. The Commissioner’s finding that dividends and deviations are profit is based upon the opinion that these are monies voluntarily surrendered by the insurance companies. Treatment of dividends and deviations as profit has been approved by this Court before. See 1996 Auto-COA, 129 N.C. App. at 668, 501 S.E.2d at 686 (citing 1994 Auto, 124 N.C. App. at 682, 478 S.E.2d at 800). In addition, designating divi*430dends and deviations as “profit” and failure to adjust the ratemaking formula with a specific provision for them does not mean that the due consideration required by statute has been denied. Here, the Commissioner listed each expert witness’s treatment of dividends and deviations in his findings of fact. The Commissioner then stated why he found one expert’s opinion more persuasive than the others, and why he chose to treat dividends and deviations as he did. We note again that the Commissioner is not required to numerically adjust the rates to show that he has provided due consideration of any of the factors in G.S. § 58-36-10. See 1996 Auto, 350 N.C. at 547, 516 S.E.2d at 154-55. Here, this technique of analysis indicates that the Commissioner provided due consideration to dividends and deviations as required by G.S. § 58-36-10.
The Bureau’s arguments regarding competition and premium shortfalls are essentially arguments that dividends and deviations should not be treated as profit. We reject these arguments for the reasons stated above.
The Bureau also argues that the Commissioner’s order should focus on the aggregate industry rather than the average company. The Bureau cites the following:
The statute contemplates that the rates shall be fixed with a view of the aggregate earnings and profits for the insurance business in the State. Each company may make as much money as it can. Some may make enormous profits, some may do a losing business, but the average profit, that is, the average profit on the aggregate business, must be reasonable.
1977 Auto, 300 N.C. 381, 444-45, 269 S.E.2d 547, 586 (1980) (quoting Aetna Ins. Co. v. Hyde, 285 S.W. 65 (Mo. 1926), cert. dismissed, 275 U.S. 440, 72 L.Ed. 357 (1928)). Here, the Commissioner chose to analyze the issue of dividends and deviations from the standpoint of an “average” insurance company. However, his conclusions and findings also discussed the effect of the average rate on the industry and the overall aggregate profit of the industry. Therefore, assuming that the 1977 Auto case requires the Commissioner to consider the effect of the average rate on the industry and the overall aggregate profit of the industry, he has done so according to the order.
After careful review of the record, we hold that the Commissioner’s findings and conclusions were adequately supported by the evidence and do not produce an excessive, inadequate or *431unfairly discriminatory rate. Accordingly, this assignment of error is overruled.
III.
The Bureau also contends that the Commissioner improperly calculated the investment income available from policyholder-supplied funds. The Commissioner found that rate deviations should not be included in the calculation of the investment of policyholder-supplied funds. The Commissioner also found that no reduction in investment income should be included to account for agents’ balances and prepaid expenses. We conclude that sufficient evidence supports the Commissioner’s findings and conclusions.
As the Commissioner stated in his findings, investment income is dependent upon three factors: (1) the amount of money invested, (2) the length of time the funds are invested, and (3) the rate of return. Here, the Bureau disputes the Commissioner’s decision regarding the first two factors — the amount invested and the duration of the investment. The Bureau argues that rate deviations reduce the amount of premiums that insurance companies are able to invest. The Commissioner calculated the amount of money available for investment without reducing that amount to account for rate deviations. The Commissioner based his calculation upon the testimony of Department of Insurance’s expert witness Schwartz. Also, the Commissioner considered deviations within his calculation of the underwriting profit provision. If rate deviations were also considered within the investment income from policyholder-supplied funds portion of the equation, deviations would be counted twice. This double-counting would produce an excessively high rate of return on insurance operations according to the Commissioner’s ratemak-ing formula. Therefore we hold that the Commissioner’s refusal to reduce investment income from policyholder-supplied funds in order to consider rate deviations is supported by material and substantial evidence.
The Bureau also faults the Commissioner’s refusal to reduce the estimated investment income projection as a result of agents’ balances and prepaid expenses. Agents’ balances occur when insurance policyholders pay for their coverage in installment payments throughout the policy term. “Prepaid expenses” refers to the insurance companies’ practice of paying expenses from their reserve funds before the policy premiums are paid by consumers. The Bureau argues that agents’ balances and prepaid expenses negatively affect *432overall investment income. Both agents’ balances and prepaid expenses reduce the amount of time policyholder-supplied funds are invested. The Commissioner based his calculations on the assumption that the insurance company would have the full manual rate premium over the entire coverage period. The Commissioner found that his treatment of agents’ balances and prepaid expenses was consistent with the testimony of expert witnesses Cohn and Schwartz. In addition, the Commissioner stated that his calculations were consistent with the calculations used to set rates that were examined in the 1994 and 1996 Auto opinions.
In 1994 Auto, this Court wrote:
Section F of the Commissioner’s order examined the issue of investment income from unearned premium, loss, and loss expense reserve funds [or “policyholder-supplied funds”]. In this section, the Commissioner clearly defined the factors involved in considering investment income; selected a reasonable rate of return (7%) on investments; and carefully explained why he concluded the Bureau’s amount of reserves subject to investment was incorrect.
1994 Auto, 124 N.C. App. at 691, 478 S.E.2d at 805. Here, the Commissioner summarized the evidence given by the expert witnesses on both sides of the dispute. The Commissioner noted that two expert witnesses had adopted his treatment of agents’ balances and prepaid expenses from the 1994 and 1996 Auto cases. Then the Commissioner summarized his method of calculating investment income on policyholder-supplied funds in the previous orders. After finding that the Bureau had not offered new evidence on this matter, the Commissioner found that his calculation in the 2001 order was identical to the one approved by this Court in the earlier filing. Adopting the reasoning of this Court in 1994 Auto, the Commissioner found that:
433. The policy reason for disallowing deductions for agents’ balances and prepaid expenses is that, unlike the customary consumer transactions, in an insurance transaction the policyholder must pay for the insurance benefit in advance of the service provided. This pre-payment of premiums allows the insurance companies to invest this unearned revenue for profit. For this reason, policyholders, should, in the ratemaking process, receive the full benefit of income that results from investing policyholder funds.
*433Also see 1994 Auto, 124 N.C. App. at 691, 478 S.E.2d at 805. The Commissioner also repeated this Court’s finding that agents’ balances and prepaid expenses were within the control of the individual insurance companies and should not impact the ratemaking process in a way that disadvantages consumers. We conclude that there is substantial evidence in the record to support the Commissioner’s calculation of investment income from policyholder-supplied funds.
IV.
The Bureau’s final argument on appeal is that the Commissioner erred by substituting his ratemaking procedure without first finding that the Bureau’s procedure would produce excessive, inadequate or unfairly discriminatory rates. We disagree.
The Bureau takes exception to the Commissioner’s rejection of its data set. The Bureau’s calculations were based upon one year of data that met certain reliability standards. The Bureau had used the one year data set in previous filings without objection from the Commissioner. However, here the Commissioner chose to use a three-year average data set instead. The Commissioner found that “[t]he use of three years of data will produce rates that are neither inadequate, excessive or unfairly discriminatory.” The Commissioner did not find that the Bureau’s data would produce excessive, inadequate or unfairly discriminatory rates. The Bureau contends that without this specific finding regarding its data, the Commissioner could not substitute his own data set. This argument is not persuasive.
G.S. § 58-36-10(1) states that “[r]ates or loss costs shall not be excessive, inadequate or unfairly discriminatory.” “If the Commissioner after the hearing finds that the filing does not comply with the provisions of this Article, he may issue an order disapproving the filing, determining in what respect the filing is improper, and specifying the appropriate rate level or levels that may be used . . . .” G.S. § 58-36-70(d). These two statutes focus upon the propriety of the entire filing instead of specific parts of the filing. As a result, we hold that the Commissioner is not required to find each portion of the Bureau’s filing improper before he can substitute his own ratemaking structure. Instead, the plain language of G.S. § 58-36-70(d) indicates that the Commissioner must analyze the entire rate filing to determine whether the overall calculation will result in excessive, inadequate or unfairly discriminatory insurance rates. Therefore, it was not necessary for the Commissioner to find that the data set used by *434the Bureau would produce a calculation that created rates that were excessive, inadequate or unfairly discriminatory. The Commisioner, in order to use his own data or calculations, or to set rates, must only conclude that the Bureau’s filing as a whole would result in excessive, inadequate or unfairly discriminatory rates. Here, the Commissioner concluded:
II. Inasmuch as the Bureau has failed to give due consideration to the factors set forth in Conclusions of Law, Part I, the Bureau’s proposed rate level increase for private passenger cars of ten and six tenths percent (+10.6%) is excessive and unfairly discriminatory for the reasons set forth in Findings Part I through Part VI and elsewhere in this Order, which are incorporated herein by reference. Accordingly, the Bureau’s request for a rate increase of ten and six tenths percent (+10.6%) is denied and the filing is disapproved.
Because the Commissioner’s conclusion was adequately supported by material and substantial evidence, this assignment of error is overruled.
V.
After careful review of the record, we hold that the Commissioner’s order establishes a rate level that is not inadequate, excessive or unfairly discriminatory. The Commissioner appropriately considered the factors outlined in G.S. § 58-36-10 and applied his discretion according to the limits of the 1994 Auto and 1996 Auto opinions. The Commissioner’s findings of fact are supported by material and substantial evidence. For the foregoing reasons, the Commissioner’s order setting automobile and motorcycle liability insurance rates is affirmed.
Affirmed.
