             Report of Independent Registered Public Accounting Firm

To the Participants, Administrator and Compensation Committee of
Albany International Corp. Prosperity Plus Savings Plan

In our opinion, the accompanying statements of net assets available for benefits
and the related statements of changes in net assets available for benefits
present fairly, in all material respects, the net assets available for benefits
of Albany International Corp. Prosperity Plus Savings Plan (the "Plan") at
December 31, 2006 and 2005, and the changes in net assets available for benefits
for the years then ended in conformity with accounting principles generally
accepted in the United States of America. These financial statements are the
responsibility of the Plan's management. Our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these statements in accordance with the standards of the Public
Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule of assets (held
at end of year) is presented for the purpose of additional analysis and is not a
required part of the basic financial statements but is supplementary information
required by the Department of Labor's Rules and Regulations for Reporting and
Disclosure under the Employee Retirement Income Security Act of 1974. This
supplemental schedule is the responsibility of the Plan's management. The
supplemental schedule has been subjected to the auditing procedures applied in
the audit of the basic financial statements and, in our opinion, is fairly
stated in all material respects in relation to the basic financial statements
taken as a whole.

Prosperity Plus Savings Plan

1.    Description of Plan

      The following description of the Albany International Corp. (the
      "Company") Prosperity Plus Savings Plan (the "Plan") provides only general
      information. Participants should refer to the Plan agreement for a more
      complete description of the Plan's provisions.

      General
      The Plan is a defined contribution plan and is subject to the provisions
      of the Employee Retirement Income Security Act of 1974 (ERISA). The Plan
      covers all full time domestic employees of the Company and its
      subsidiaries who are 21 years of age or older.

      Contributions
      Employees may make voluntary contributions to the Plan of 1% to 15% of
      eligible compensation, subject to certain limitations, on a before-and/or
      after-tax basis as defined in the Plan. Participants may also contribute
      amounts representing distributions from other qualified defined benefit or
      defined contribution plans. Participants direct the investment of their
      contributions into various investment options offered by the Plan. The
      Plan currently offers thirteen registered investment companies, a
      common/collective trust, a brokerage option and Albany International Class
      A common stock. The Company makes a matching contribution to the Plan in
      varying percentages up to 5% of the participant's eligible compensation
      (which may be in a combination of both shares of Company Class A stock and
      cash). Employees may convert any of the Albany International Class A
      common stock in their match and profit sharing accounts into the other
      available investment fund options.

      During 2006 and 2005, the Company's matching contributions of $4,381,961
      and $4,260,993 included $4,100,583 (114,206 shares) and $3,985,319
      (116,711 shares) of Albany International Class A common stock,
      respectively.

      Profit-Sharing Contribution
      The Plan provides for a profit-sharing contribution. Profit-sharing
      contributions are based upon a minimum 1% employee participation in the
      Plan and are in addition to, and separate from, Company matching
      contributions. In order to receive a profit-sharing contribution, an
      employee must be an active contributing participant in the Plan during the
      final quarter of the year for which the profit-sharing contribution is
      made, unless the employee has been suspended from participation because of
      a hardship withdrawal. If an employee is eligible, yet chooses to
      participate for less than a full year, the profit-sharing contribution
      will be pro-rated. An employee who retires during the year is also
      eligible to receive a profit sharing contribution on a pro-rata basis. The
      amount of the profit sharing contribution is based on a formula stated at
      the beginning of the year. The Company's contribution for profit-sharing
      may be made in either cash or Albany International Class A common stock
      (or both) following the end of the year.

      The profit sharing contributions were $940,391 and $2,256,903 for the
      years ended December 31, 2006 and 2005, respectively. Profit sharing
      contributions paid during the years ended December 31, 2006 and 2005
      included $2,114,301 (61,641 shares) and $1,371,376 (40,087 shares),
      respectively, of Albany International Class A common stock.

      Participant Accounts
      Each participant's account is credited with the participant's contribution
      and allocations of (a) the Company's contributions and (b) Plan earnings.
      Allocations are based on participant earnings or account balances, as
      defined. The benefit to which a participant is entitled is the benefit
      that can be provided from the participant's vested account.

      Vesting
      Participants are vested immediately in their and the Company's
      contributions plus actual earnings thereon.

      Pension Purchase
      The Plan allows retiring plan participants to purchase additional pension
      benefits by transferring existing Plan account balances to the Company's
      Pension Plus Plan. The decision to make a pension purchase must be made 60
      days prior to retirement. Once the pension purchase option is elected, the
      election is irrevocable after retirement.

      Payment of Benefits
      Upon termination of service, total disability, death or retirement,
      participants have the option to receive an amount equal to the value of
      their accounts in a lump sum payment or, in the case of total disability
      or retirement, monthly installments over a period not to exceed 15 years.
      Participants may also elect prior to retirement to withdraw up to 100% of
      their after-tax contributions and up to 100% of before-tax contributions
      if the Internal Revenue Service's criteria for "financial hardship" are
      met.

      Plan Termination
      The Company intends to continue the Plan indefinitely but reserves the
      right to modify, amend, suspend or terminate the Plan. In the event of
      plan termination, distributions would be allocated based on the value of
      the participant accounts.

      Administrative Costs
      The Plan stipulates that all costs incurred in administering the Plan
      shall be borne by the Company or, if the Compensation Committee so
      determines, by the Plan. The Company paid Plan administrative expenses of
      $75,466 and $69,288 during 2006 and 2005, respectively.

2.    Summary of Significant Accounting Policies

      Estimates
      The preparation of the financial statements in conformity with accounting
      principles generally accepted in the United States of America requires
      Plan management to make estimates and assumptions that affect the reported
      amounts of assets and liabilities and disclosure of contingent assets and
      liabilities at the date of the financial statements and the reported
      amounts of changes in net assets during the reporting period. Actual
      results could differ from those estimates.

      As described in Financial Accounting Standards Board Staff Position, FSP
      AAG INV-1 and SOP 94-4-1, Reporting of Fully Benefit-Responsive Investment
      Contracts Held by Certain Investment Companies Subject to the AICPA
      Investment Company Guide and Defined-Contribution Health and Welfare and
      Pension Plans (the FSP), investment contracts held by a
      defined-contribution plan are required to be reported at fair value.
      However, contract value is the relevant measurement attribute

      for that portion of the net assets available for benefits of a
      defined-contribution plan attributable to fully benefit-responsive
      investment contracts because contract value is the amount participants
      would receive if they were to initiate permitted transactions under the
      terms of the plan. The Plan invests in investment contracts through a
      collective trust. As required by the FSP, the statements of net assets
      available for benefits presents the fair value of the investment in the
      collective trust as well as the adjustment of the investment in the
      collective trust from fair value to contract value relating to the
      investment contracts. The statement of changes in net assets available for
      benefits is prepared on a contract value basis. The FSP has been applied
      retroactively and accordingly, the statement of net assets available for
      benefits at December 31, 2005 has been updated to reflect the requirements
      of the FSP.

      Risks and Uncertainties
      The Plan provides for various investment options in any combination of
      stocks, bonds, mutual funds and other investment securities. Investment
      securities are exposed to various risks, such as interest rate, market and
      credit. Due to the level of risk associated with certain investment
      securities and the level of uncertainty related to changes in the value of
      investment securities, it is at least reasonably possible that changes in
      risks in the near term would materially affect participants' account
      balances and the amounts reported in the statements of net assets
      available for benefits and the statement of changes in net assets
      available for benefits.

      Investment Valuation and Income Recognition

      The Plan's investments are stated at fair value.
      Investments in registered investment companies are valued at the latest
      quoted sales price on the last business day of the year, which represents
      the net asset value of shares held by the Plan at year end.

      The investment in the common/collective trust is recorded at fair value
      (prior to adjustment to contract value) based on the Plan's share of the
      fund's net asset value.

      The common stock of Albany International Corp. is valued at the latest
      quoted price on the last business day of the year.

      Participant loans are valued at cost which approximates fair value.

      Security transactions are recorded on a trade-date basis. Gains or losses
      on sales of securities are based on average cost.

      Dividend income is recorded on the ex-dividend date. Dividends declared by
      the Board of Directors of the Company on Albany International Corp. Class
      A common stock may be reinvested in the Plan or received as a cash
      distribution as elected by the participant. Total cash dividends received
      by participants included in payment of benefits are $348,418 and $311,145
      for the years ended December 31, 2006 and 2005, respectively. Interest
      income is recorded as earned.

      The Plan presents in the statement of changes in net assets available for
      benefits the net appreciation in the fair value of its investments, which
      consists of realized gains and losses and unrealized
      appreciation/depreciation on those investments.

      Payment of Benefits
      Benefit payments are recorded when paid.

      Reclassifications
      Certain amounts in the December 31, 2005 financial statements have been
      reclassified to conform to the 2006 presentation.

      New Accounting Pronouncement
      In September 2006, the FASB issued FAS No. 157, "Fair Value Measurements"
      (FAS No. 157). FAS No. 157 clarifies the principle that fair value should
      be based on the assumptions market participants would use when pricing an
      asset or liability and establishes a fair value hierarchy that prioritizes
      the information used to develop those assumptions. Under the Standard,
      fair value measurements would be separately disclosed by level within the
      fair value hierarchy. FAS No. 157 is effective for financial statements
      issued for fiscal years beginning after November 15 2007, and interim
      periods within those fiscal years, with early adoption permitted.
      Management does not expect the adoption of FAS No. 157 to have a material
      effect on the financial statements.

5.    Participant Loans

      Participants may borrow from their fund accounts a minimum of $1,000 and
      additional amounts in multiples of $500 up to a maximum equal to the
      lesser of $50,000 or 50% of their account balance. Interest rates on loans
      are determined by the Compensation Committee from time to time with the
      rate remaining constant throughout the life of the loan (rates range
      between 4.94% and 10.25% at December 31, 2006). Loans are to be repaid
      through payroll deductions, although they may be repaid in a lump sum
      amount, generally over a period from 1 to 5 years except for loans for the
      purchase of a primary residence. Home purchase loan repayments range from
      5 to 20 years.

6.    Related Party Transactions

      The Plan invests in shares of mutual funds managed by an affiliate of
      Vanguard Fiduciary Trust Company ("VFTC"). VFTC acts as trustee for the
      investments held by the Plan. The Plan also invests in shares of the Plan
      Sponsor's Albany International Class A common stock. The Plan purchased
      $8,485,240 and $7,837,853 and sold $7,485,296 and $10,005,497 of Albany
      International Class A common stock during the years ended December 31,
      2006 and 2005, respectively. Transactions in such investments qualify as
      party-in-interest transactions which are exempt from the prohibited
      transaction rules.

7.    Tax Status

      The Internal Revenue Service has determined and informed the Company by a
      letter dated January 31, 2004, that the Plan is qualified and the trust
      established under the Plan is tax-exempt, under the appropriate sections
      of the Code. The Plan has been amended since receiving the determination
      letter. However, the Plan administrator believes that the Plan is
      currently designed and being operated in compliance with the applicable
      requirements of the Code. Therefore, the Plan administrator believes that
      the Plan was qualified and the related trust was tax-exempt as of the
      financial statement date.
