The Exchange, which also commenced business in 1925, is a Pennsylvania-domiciled reciprocal insurer that writes property and casualty insurance. </span></div><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"> </span></div><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Our primary function as attorney-in-fact is to perform policy issuance and renewal services on behalf of the subscribers at the Exchange. We also act as attorney-in-fact on behalf of the Exchange with respect to all claims handling and investment management services, as well as the service provider for all claims handling, life insurance, and investment management services for its insurance subsidiaries, collectively referred to as "administrative services". Acting as attorney-in-fact in these </span><span style="font-family:inherit;font-size:10pt;"><span>two</span></span><span style="font-family:inherit;font-size:10pt;"> capacities is done in accordance with a subscriber's agreement (a limited power of attorney) executed individually by each subscriber (policyholder), which appoints us as their common attorney-in-fact to transact certain business on their behalf. Pursuant to the subscriber's agreement for acting as attorney-in-fact in these </span><span style="font-family:inherit;font-size:10pt;"><span>two</span></span><span style="font-family:inherit;font-size:10pt;"> capacities, we earn a management fee calculated as a percentage of the direct and affiliated assumed premiums written by the Exchange.</span></div><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The policy issuance and renewal services we provide to the Exchange are related to the sales, underwriting and issuance of policies. The sales related services we provide include agent compensation and certain sales and advertising support services. Agent compensation includes scheduled commissions to agents based upon premiums written as well as additional commissions and bonuses to agents, which are earned by achieving targeted measures. Agent compensation comprised approximately </span><span style="font-family:inherit;font-size:10pt;"><span>67%</span></span><span style="font-family:inherit;font-size:10pt;"> of our </span><span style="font-family:inherit;font-size:10pt;">2019</span><span style="font-family:inherit;font-size:10pt;"> policy issuance and renewal expenses. The underwriting services we provide include underwriting and policy processing and comprised approximately </span><span style="font-family:inherit;font-size:10pt;"><span>10%</span></span><span style="font-family:inherit;font-size:10pt;"> of our </span><span style="font-family:inherit;font-size:10pt;">2019</span><span style="font-family:inherit;font-size:10pt;"> policy issuance and renewal expenses. The remaining services we provide include customer service and administrative support. We also provide information technology services that support all the functions listed above that comprised approximately </span><span style="font-family:inherit;font-size:10pt;"><span>11%</span></span><span style="font-family:inherit;font-size:10pt;"> of our </span><span style="font-family:inherit;font-size:10pt;">2019</span><span style="font-family:inherit;font-size:10pt;"> policy issuance and renewal expenses. Included in these expenses are allocations of costs for departments that support these policy issuance and renewal functions.</span></div><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">By virtue of its legal structure as a reciprocal insurer, the Exchange does not have any employees or officers. Therefore, it enters into contractual relationships by and through an attorney-in-fact. Indemnity serves as the attorney-in-fact on behalf of the Exchange with respect to its administrative services. The Exchange's insurance subsidiaries also utilize Indemnity for these services in accordance with the service agreements between each of the subsidiaries and Indemnity. Claims handling services include costs incurred in the claims process, including the adjustment, investigation, defense, recording and payment functions. Life insurance management services include costs incurred in the management and processing of life insurance business. Investment management services are related to investment trading activity, accounting and all other functions attributable to the investment of funds. Included in these expenses are allocations of costs for departments that support these administrative functions. The amounts incurred for these services are reimbursed to Indemnity at cost in accordance with the subscriber's agreement and the service agreements. State insurance regulations require that intercompany service agreements and any material amendments be approved in advance by the state insurance department. </span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div>Our results of operations are tied to the growth and financial condition of the Exchange. If any events occurred that impaired the Exchange’s ability to grow or sustain its financial condition, including but not limited to reduced financial strength ratings, disruption in the independent agency relationships, significant catastrophe losses, or products not meeting customer demands, the Exchange could find it more difficult to retain its existing business and attract new business. A decline in the business of the Exchange almost certainly would have as a consequence a decline in the total premiums paid and a correspondingly adverse effect on the amount of the management fees we receive. We also have an exposure to a concentration of credit risk related to the unsecured receivables due from the Exchange for its management fee and cost reimbursements. See Note 16, "Concentrations of Credit Risk".
